3. Osmanthus fragrans has low requirements on soil and water. The soil should not be too wet, especially to avoid water accumulation.
4. It is suitable for being born in sandy loam with deep soil layer and rich humus, and can also grow normally in cohesive soil. It is suitable for growth in slightly acidic soil with PH 5.5~6.5, and alkaline soil will lead to physiological iron deficiency in osmanthus fragrans.
5. Water once in the morning and once in the evening.
Question 2: How to plant potted osmanthus trees? Planting techniques of potted osmanthus trees
The cultivation of potted osmanthus fragrans should pay attention to the following points: first, provide a suitable growth environment; Second, proper watering and timely drainage; The third is rational fertilization.
Suitable light and soil
Osmanthus fragrans likes temperature and is suitable for growing in acidic sandy loam with good drainage and rich humus. Osmanthus fragrans grows slowly in poor soil, and often does not bloom or spends less. Osmanthus fragrans likes light, but it can also be in the shade for a short time. At the same time, we should pay attention to the harm of smoke and dust. Osmanthus fragrans growing in an environment with poor air quality often cannot blossom.
Water moderately to prevent waterlogging.
Osmanthus fragrans is mainly watered within one month after new planting and in the summer of the same year. The newly planted osmanthus must be watered, but no water can be accumulated in the basin. After the rainy day, the accumulated water in the basin should be poured out in time to prevent the roots from rotting.
rational application of fertilizer
Osmanthus fragrans likes fertilization, and it is applied once every April and May. Fertilize every 7~ 10 day from June to July; Last time in early August. In this way, sweet-scented osmanthus not only grows luxuriantly, but also blooms much and smells fragrant.
Pruning of potted osmanthus fragrans
Potted osmanthus can't grow freely, so pruning osmanthus is the most important thing. If you don't prune it often, first, the tree is deformed and ugly; Second, the original flowerpot may not hold longer and bigger osmanthus trees.
Osmanthus fragrans potted plants are mostly pruned into single stem type: starting from seedlings, choose a trunk. When the trunk reaches a predetermined height, the top is cut off and 3-5 lateral branches germinate to form a crown.
After that, it is pruned once a year before germination. Pruning work is mainly to cut off dead branches, too dense branches and weak branches. If the tree shape is not good, the branches can be shortened appropriately to sprout new buds and form new branches. Remember not to prune too much, otherwise it is easy to grow branches in vain. For osmanthus fragrans with improper management and abnormal plants, the following pruning methods can be adopted:
1, a plant that grows very tall and lacks leaves at the lower part. Cut off the higher part of the trunk (the specific height should be according to personal preference) to promote the germination of the lower trunk and grow into new branches. In the second year, cut off the miscellaneous branches according to the desired tree shape.
2. After pruning and shaping, osmanthus trees should strengthen water and fertilizer management to ensure ventilation. After shaping, it is found that the buds at the base or middle of the trunk may affect the tree shape, so they should be pulled out in time.
Question 3: Osmanthus fragrans, as a unique ornamental and economic tree species in China, how to plant it? There are four common cultivars of osmanthus fragrans: Jingui, Yin Gui, Dangui and Sijigui. Among them, Jingui has the highest economic value, and their reproduction generally adopts cutting, layering and grafting. However, if cutting propagation is carried out by general methods, the survival rate is very low; Air pressure and ground pressure are commonly used in layering. Although the survival rate is high, the reproductive coefficient is very low. Through grafting, the survival rate of grafting is not high, and the development of osmanthus fragrans is limited to some extent due to the difficulty of reproduction and the limitation of the source of seed strips.
2
Cultivated varieties can be propagated by sowing, grafting, cutting or layering; Seeds have a post-ripening period and need to be stored in sand for about half a year before sowing. Cutting before germination in spring, selecting annual branches as cuttings, inserting them into plain sandy soil or peat soil, covering with plastic film, keeping cool, and rooting after beginning of autumn. When a large number of seedlings are propagated, Ligustrum lucidum grows rapidly. Mostly used in the north, biennial Ligustrum lucidum seedlings. Used as rootstock in the south. Before germination in spring, cuttage grafting should be carried out at 5 cm above the ground. Potted osmanthus fragrans in the north is propagated by docking from solstice to dawn in summer. In early spring, Ligustrum microphyllum was planted in a pot, and then butted with branches with similar thickness on the osmanthus tree. Before and after exposure, the scion is cut from the mother, and the branches above the rootstock interface are also cut.
three
Osmanthus fragrans is cultivated in the open field and potted. Potted plants are used in the north.
There are more osmanthus flowers planted in the open field than in early spring. The planting site should be sunny, well drained and deep in soil. Dig a big pit before planting, apply more organic fertilizer and plant ash at the same time. Seedlings need to be transplanted with soil ropes in order to survive. Fully irrigate after planting. Apply liquid fertilizer once after survival. Apply 1 ~ 2 times water and fertilizer in July and August. Before winter, compost is now used. In the future, the available nitrogen fertilizer was applied once in late March, the available phosphorus and potassium fertilizer was applied once in July, and the organic fertilizer was applied once again in June at 5438+ 10. After each fertilization, irrigation and intertillage weeding should be done in time, and attention should be paid to timely prevention and control of pests and diseases, which can accelerate growth and make flowers flourish and smell fragrant every year.
In order to make Osmanthus fragrans bloom more and more fragrant in potted plants, we need to grasp five main links, such as selecting pot soil, watering in time, applying topdressing skillfully, pruning properly and controlling pests and diseases.
four
Matters needing attention in how to plant osmanthus trees;
1. Osmanthus fragrans likes slightly acidic soil. Potted plants can be mixed with 5 parts of mountain mud or humus, 3 parts of garden soil and 2 parts of sandy soil, or mixed with half of humus and sandy loam as culture soil.
2. Water in time. Watering should master "two less and one more", that is, water less before new buds appear, water less in rainy days and water more in dry weather in summer and autumn. It is advisable to keep the water content of basin soil at about 50% at ordinary times. Especially when flowering in autumn, if the pot soil is too wet, it is easy to cause falling flowers. Pay attention to inspection in rainy days. If there is water in the basin, pour water from the side basin in time to avoid root rot after a long time.

3. Skillfully apply topdressing. After osmanthus fragrans germinated in spring, fully decomposed pancake fertilizer was applied every 10 day to promote germination and branching. After July, apply diluted decomposed chicken and duck manure or fish into the water, or add 0.5% calcium superphosphate to the fertilizer solution.
Promote germination and differentiation. At the beginning of September, when the liquid fertilizer based on phosphate fertilizer was applied for the last time, osmanthus fragrans flourished and the flowers were delicious. Insufficient fertilization, especially phosphate fertilizer, will result in fewer branches, fewer flowers and no fragrance.
six
4, appropriate pruning. Osmanthus fragrans has developed root system and strong germination. Mature osmanthus trees branch twice a year, in spring and autumn respectively. Therefore, in order to make Osmanthus fragrans flourish, it is necessary to prune it properly to maintain the physiological balance between reproductive growth and vegetative growth. Therefore, it needs pruning once after flowering in autumn. According to the growth potential of the plant, in addition to thinning the dense branches, the long branches in summer and autumn should also be cut off, so that thick and short branches are evenly left on each side branch. The second pruning is carried out before germination in early spring, and orange branches, twigs and insect branches are cut off to facilitate ventilation and light transmission, and promote osmanthus fragrans to breed more and fuller flower buds. During the growth period, the budding branches should be cut frequently to facilitate the concentration of flower cultivation, and then the flowers will flourish. In addition, potted osmanthus plants should be short and strong, with compact branches and thick trunks. Change pots in early spring every 1 ~ 2 years. In late autumn in the north, osmanthus fragrans should be moved to a cold room above 0℃ for wintering, so as to keep the soil slightly wet and make it fully dormant, which is conducive to flowering in the next year. In the next year, Tomb-Sweeping Day will move it to a sunny place for maintenance.
seven
5, pest control. Osmanthus fragrans is prone to anthracnose, brown spot disease, plaster disease, Fusarium wilt, algae spot disease, soot disease, whitefly, scale insect, moth, thorn moth, grasshopper, osmanthus leafhopper and other pests, which need to be sprayed in time for control. ...& gt& gt
Question 4: How to plant osmanthus trees, it is best to be comprehensive. Grown-up individuals think that plants have strong vitality, as long as they are fertilized and watered regularly. To urge flowers, it is necessary to let osmanthus blossom ahead of time. Theoretically speaking, because osmanthus fragrans is a plant with long sunshine, long sunshine means short night. In the flower bud differentiation stage, you can make up a period of light in the middle of the night, and you can bloom ahead of time after a while. The following information is for your search to see if it is helpful to you. Osmanthus fragrans is a long-day plant, which likes to grow in places with abundant sunshine, deep soil layer and good drainage. The soil is slightly acidic with a pH value of 5.5 ~ 6.5. Avoid alkaline earth, be afraid of stagnant water and oil fume.
(1) There are more osmanthus flowers planted in the open field than in early spring. The planting site should be sunny, well drained and deep in soil. plant
Dig a big pit first, apply more organic fertilizer and add some plant ash at the same time. Seedlings need to be transplanted with soil ropes in order to survive. Fully irrigate after planting. success
Apply liquid fertilizer once after living. Apply 1-2 times water and fertilizer in July and August. Before winter, compost is now used. After that, it will be applied once a year in late March.
Nitrogen fertilizer, topdressing available phosphorus and potassium fertilizer in July, and applying organic fertilizer in June at 5438+ 10. Irrigation and intertillage weeding should be carried out in time after each fertilization, and injections should be given at ordinary times.
It is necessary to prevent and control pests and diseases in time, so as to speed up the production of ingots, which bloom luxuriantly every year and are full of flowers.
(2) In order to make Osmanthus fragrans blossom more and smell better in potted plants, we need to grasp five main links, such as selecting pot soil, watering in time, applying topdressing skillfully, pruning properly and controlling pests and diseases. Potted soil can be made of mountain mud, humus and sandy soil with a ratio of 5: 3: 2, or half humus and sandy loam. Osmanthus fragrans should master the principle of "two less and one more", that is, water less before new buds appear, water less in rainy days and water more in dry weather in summer and autumn. It is advisable to keep the basin soil half dry and half wet when watering at ordinary times. Take shelter from the rain in rainy days and drain in time to prevent the water in the basin from rotting roots. Don't water too much in winter, otherwise it will easily cause leaves to fall or even die of waterlogging. Generally, it is "completely watered if you don't do it." After fertilization and spring germination, apply 1 times of fully decomposed cake fertilizer and water every 10 day to promote its branching. After July, liquid fertilizer, mainly phosphate fertilizer, was applied to promote flower bud differentiation. If fertilization, especially phosphate fertilizer, is insufficient, there will be fewer branches, fewer flowers and less fragrance. Before entering the house in winter, you can sprinkle bean cake powder or pour thick fertilizer on the surface of the pot soil for the winter. Pruning osmanthus fragrans has developed root system and strong germination. Therefore, in order to make Osmanthus fragrans flourish, it is necessary to prune it properly to keep the balance between reproductive growth and vegetative growth. Generally, it is necessary to cut off long branches, weak branches, pests and diseases to facilitate ventilation and nutrient concentration, and promote osmanthus to breed more and fuller flower buds.
Cultivated varieties can be propagated by sowing, grafting, cutting or layering; Seeds have a post-ripening period and need to be stored in sand for about half a year before sowing. Spring cuttings
Before seasonal germination, select annual branches as cuttings, insert them into plain sandy soil or peat soil, cover them with plastic film, maintain them in the shade, and take root after autumn. When a large number of seedlings are propagated, Ligustrum lucidum grows rapidly. Mostly used in the north, biennial Ligustrum lucidum seedlings. Used as rootstock in the south. Before germination in spring, cuttage grafting should be carried out at 5 cm above the ground. Potted osmanthus in the north is propagated from the solstice to dawn in summer. In early spring, Ligustrum microphyllum was planted in a pot, and then butted with branches with similar thickness on the osmanthus tree. Before and after exposure, the scion is cut from the mother, and the branches above the rootstock interface are also cut.
Osmanthus fragrans likes warm, dry and sunny environment and fertile and well-drained slightly acidic soil. Potted osmanthus buds every spring.
Change the soil 1 time, and trim the densely aged fibrous roots properly. From April to September, it should be cultivated in a ventilated and sunny place, and the water should be dry and wet. Avoid watering too much or accumulating water in the basin after rain. During flowering, you should not water too much. Otherwise, it is easy to cause bud drop.
Osmanthus fragrans likes fertilizer, and dilute liquid fertilizer 1 time is applied every 7 ~ 10 days in the growing season. Apply dry fertilizer 1 time before and after flowering (about 50 grams of sauce residue per pot).
Before flowering, it can promote flowering; Application after flowering will promote the growth of new branches in the coming year. Osmanthus fragrans is an aromatic flower, and it likes fertilizers containing phosphorus and potassium. Therefore, during the whole growth period, more fertilizers containing phosphorus and potassium should be applied appropriately. In late autumn, it is necessary to move to a cold room above 0℃ for wintering, so as to keep the basin soil slightly moist and make it fully dormant, which is conducive to flowering in the coming year.
Osmanthus fragrans is sunny, dry and evergreen in all seasons. Proper management can make osmanthus bonsai flourish, bloom year after year, and the flowers are overflowing.
First, change the pot. When the average plant is 50 cm high, use a 24 cm flowerpot; When the plant grows to 80 cm, use a 32 cm flowerpot. When you change it into a big flowerpot, you can change it into three ... >>
Question 5: What should we pay attention to when planting osmanthus in the courtyard? Which plants can't be planted? After long-term planting, natural hybridization and artificial breeding, osmanthus fragrans has produced many cultivated varieties. Through further investigation and arrangement, 32 osmanthus fragrans varieties were preliminarily identified. As far as color is concerned, there are Jingui, Yin Gui and Dangui. From the leaf type, there are willow leaf laurel, golden leaf laurel, dripping yellow, sunflower leaf and firewood handle yellow; As far as the flowering period is concerned, there are eight laurels, four seasons of laurel and beautiful months. At present, there is no unified variety classification in China. It is customary to divide osmanthus fragrans into the following four varieties: Jingui, Yin Gui, Dangui and Sijigui. Four Osmanthus fragrans varieties groups were formed: Sijigui varieties group: shorter plants, more buds, less fragrant flowers than Yin Gui, Jingui and Dangui, with lemon yellow or light yellow flowers. There are four varieties of Cinnamomum cassia and Cinnamomum cassia. Flowering in all seasons, there are varieties such as "Gui Yue", "Nissin Osmanthus fragrans", "Big-leaf Buddha Dingzhu" and "Four-season Osmanthus fragrans". Yin Gui Variety Group: It blooms in autumn, and its color is pure white, milky white, yellow white or light yellow. The varieties are broad-leaved seed Yin Gui, willow Yin Gui, hard leaf Yin Gui, seed Yin Gui, Jiulong Yin Gui, early Yin Gui, late Yin Gui, Baijie Yin Gui and Qingshan Yingui. Jingui Variety Group: Flowering in autumn, with lemon yellow to golden yellow flowers. The varieties are Dahua Jingui, Dayehuang, Huangchuan Jingui, Late Jingui, Round Leaf Jingui, Xianning Late Jingui, Qiugui, Bianyuan Jingui, Willow Sugui, Jinshigui, and Boye Jingui. Osmanthus fragrans variety group: it blooms in autumn, and its color is dark, orange yellow, orange yellow, orange red to vermilion. The varieties are cinnabar osmanthus, big leaf osmanthus, small leaf osmanthus and tooth osmanthus.
Question 6: What should I pay attention to when transplanting osmanthus trees? Transplanting season and selection of osmanthus trees
In the transplanting season, the transplanting time of osmanthus fragrans is too early, the temperature is high, the transpiration is large, the root system is easily damaged, and the water absorption capacity is weakened, which often leads to defoliation and even death. Because most osmanthus trees are transplanted from the south, it is too late, there is no transition stage, it can not adapt to the northern climate, and it is easy to freeze to death. Even if it survives, it is only a few backbone branches with sparse branches and leaves, which can not meet the engineering requirements. Through exploration, the best time for osmanthus fragrans in Zhengzhou is165438+1mid-October. At this time, the temperature began to drop, the transpiration was small, the ground temperature was high, and the injured root wound healed quickly. At the same time, some capillary roots can grow on the roots, which can alleviate the lack of nutrient absorption capacity and ensure the osmanthus tree to survive the winter smoothly.
Osmanthus fragrans should be selected with full tree shape, lush foliage, no pests and diseases, and easy to dig and lift.
Preparation before transplanting
Dig a tree pit about a week before transplanting, and dig the tree pit in the newly planted land. The diameter of the pre-dug tree pit is about 1 m larger than the packaging diameter of the transplanted tree (convenient for workers to operate in the pit), and the height should be equal to the packaging height of the transplanted tree. The excavated topsoil and subsoil are placed separately, the soil is spread out to dry, and impurities such as bricks and tiles in the soil are cleaned up. Then ferrous sulfate is added according to the ratio of 10:1(soil is10 parts) to increase soil acidity, disinfect soil and enhance fertility.
Pruning osmanthus fragrans is one of the keys to transplant survival. Because osmanthus fragrans is not strong in sprouting, it is not suitable to cut off the stems and branches. Only the leaves of osmanthus fragrans can be trimmed, and the leaves are cut off with scissors, leaving the petiole to protect the axillary buds and retaining one third of the original leaves. This can not only reduce the evaporation of water, but also retain the beauty of the original crown.
Seedling raising and transportation
It is best to transplant osmanthus in hard packaging. The big osmanthus tree to be transplanted should be watered once a week in advance so that its roots can absorb enough water. This makes it easy to dig into balls, and the soil balls will not be scattered because the soil is too dry. The diameter of the soil ball should be 6 ~ 8 times the diameter of the plant crown above the ground 1 m, and the height should be 70% of the diameter of the soil ball. You'd better dig it out if you can. When digging, the topsoil at the base of the trunk should be removed, and a quadrangular trapezoid should be dug according to the required diameter. The diameter of the lower opening is 1/3 of that of the upper opening, and the diameter of the dug ball is 5 ~ 10cm larger than that of the formwork (to fasten the soil ball with the formwork). While digging the earth ball, prepare the template, threading wire (made of steel wire) and iron wire, and get ready for packing the earth ball in time after digging. The big roots that need to be cut off when digging the ball should be sawed off with a hand saw, not with other tools. The cross section of the root should be made into paste with sulfur powder and ABT rooting agent according to the ratio of 3: 2 for treatment. After digging the soil ball, quickly fasten the formwork, tighten it with threads, wrap the trunk with straw rope and lift it.
When transporting osmanthus to the vehicle, it should be placed upright. The original soil (the old soil for digging the ball) should be wrapped around the soil ball with woven bags, and the crown should be tightly wrapped with plastic film to prevent it from moving and shaking during transportation.
Planting and post-management
Before planting, the pre-dug tree pit should be backfilled with the original soil brought back from 10 ~ 15cm. Because osmanthus trees are not flood-resistant, the planting depth of osmanthus trees is 10 to15cm higher than the original ground. First, hang the osmanthus tree and put it in the original growth direction, then put a plastic pipe at each corner of the tree pit to increase the permeability of the root after filling the tree pit. Then dismantle the formwork in turn, backfill the soil to 1/3 of the height of the soil factory, and fill the original soil near the soil ball, and fill a layer to prevent the soil ball from being broken. All tree pits are filled, cofferdam, supported and watered for the first time.
The first management in the later period is to water again 3 ~ 4 days before the first watering. Second, after the water is completely dried in the shade, the residual soil around the original tree pit is surrounded by roots, forming a mound with high middle and low sides, so that the osmanthus tree will not be drowned due to accumulated water. Third, the spring water must be watered once next spring. Fourth, spray the leaves and branches with the mixed solution of potassium dihydrogen phosphate and bactericide (carbendazim, etc.). Once every half month, the average temperature is about 20℃. It not only topdressing the leaves of osmanthus trees, but also plays a role in sterilization. ...& gt& gt
Question 7: What should I pay attention to when planting osmanthus fragrans and huanggulan? Osmanthus fragrans likes warm and humid climate. It is a subtropical tree species with high temperature resistance but not very cold. The requirements for soil are not too strict. Except alkaline soil and low-lying land or soil that is too sticky and poorly drained, it can generally grow, but the slightly acidic sandy loam with deep soil layer, loose fertility and good drainage is the most suitable. To plant osmanthus fragrans, we should take the trunk as the center, with a diameter of 1 m, and focus on loosening soil and weeding. After irrigation or rainfall, intertillage and loosen the soil to prevent soil hardening; Osmanthus fragrans is mainly watered within one month after new planting and in the summer of the same year. Newly planted osmanthus fragrans must be watered and permeable, and the canopy of the plant should be sprayed with water conditionally to maintain a certain air humidity. Osmanthus fragrans is not tolerant to waterlogging, so timely drainage or transplanting waterlogged plants with a certain amount of sand planting can promote the growth of new roots; Fertilization should be based on the principle of thin fertilizer and diligent application, with quick-acting nitrogen fertilizer as the main fertilizer, and medium and large seedlings should be fertilized three or four times a year. In early spring, apply organic fertilizer to the tree tray to promote the growth of spring shoots. Inorganic fertilizer or garbage miscellaneous fertilizer should be applied in early winter. In the meantime, fertilization can be applied once or twice according to the growth of osmanthus fragrans. Newly transplanted osmanthus fragrans should not be topdressed too early. The base fertilizer of the transplanting pit should be mixed with soil before covering it. Stripping useless buds from the lower part of the trunk when osmanthus fragrans germinates; Maintain a certain branch height and cut off useless branches. The branch height of osmanthus fragrans after general timber is about1.5m; Cut off the overgrown branches of the Ministry of Industry to keep the height of osmanthus fragrans at about 3.5 meters and the crown width at 2.5 to 3 meters. Precautions for planting chamomile: white orchid. The scientific name is Xiaoxiao, Magnoliaceae. Description: Evergreen trees, namely deciduous trees, chamomile: also known as white orchids, potted plants are usually 3-4 meters high, and there are also small plants, with gray bark, alternate leaves, turquoise luster, oblong flowers, white or yellowish petals, thick petals, long lanceolate and fragrant. If the temperature is right in winter, there will be flowers blooming continuously, but the fragrance is not as strong as that of summer flowers. Decorative application: white orchids stand upright and have branches, which are graceful and luxurious. It can be cultivated in the open-air courtyard in the south and potted in the north, and can be arranged in the courtyard, hall and conference center. Small and medium-sized plants can be placed in the living room and study. Because you are afraid of smoke, you should put it in a place with good ventilation. Water: because of fleshy roots, I am afraid of water accumulation and it is not dry. Summer is morning and evening 1 time. If it is too dry, you must spray foliar water. 2-3 days in autumn 1 time; Do not water in winter, as long as the pot soil is slightly wet; Drain the accumulated water in time after the rain. Fertilizer: Apply thin fertilizer frequently, preferably cake fertilizer, and don't apply fertilizer in winter. From germination to June, water 1 time every 3-4 days, and water 1 time every 5-6 days from July to September. After applying fertilizer several times, stop applying 1 time. Temperature: not cold-resistant. Except for South China, other areas should be maintained in winter, and the lowest room temperature should be kept above 5℃. It is suitable to leave the house from Qingming to Grain Rain, and the breeding is mainly grafting.
Question 8: How to plant osmanthus fragrans in the open field (1)? Osmanthus fragrans is planted in the field, mostly in spring. The planting site should be well drained, sunny and deep in soil. Dig a big pit before planting osmanthus trees, apply organic fertilizer regularly, and apply more plant ash at the same time. Osmanthus fragrans seedlings need to be transplanted with soil ropes, which will improve the survival rate. Osmanthus fragrans seedlings should be watered frequently and kept moist after planting. Apply liquid fertilizer once after osmanthus seedlings survive. From July to August, we should now apply 1-2 times of water and fertilizer. Winter is coming.
Previously, it was applied in the form of decomposed compost. After that, apply available nitrogen fertilizer once in March, available phosphorus and potassium fertilizer once in July and organic fertilizer once in 10. at certain intervals
After the second fertilization, remember to fully irrigate and weed the osmanthus trees so that they can absorb nutrients in time. If you want to plant osmanthus trees well, you need osmanthus trees very much.
Planting techniques, usually pay attention to timely prevention and control of pests and diseases, so as to accelerate growth, flowers blooming year after year, flowers overflowing.
(2) flowerpot planting. If you want osmanthus fragrance, you need to find a pot of soil, water it in time, apply topdressing skillfully, trim it properly, and prepare for disease prevention.
Insects and other five main links. Mountain mud, humus soil and sandy soil can be selected for planting soil, and the principle of "two less and one more" should be mastered for watering osmanthus fragrans, that is to say, water less before new buds appear.
Water, less water in rainy days, more water in dry weather in summer and autumn. In daily life, it is advisable to water the soil in the basin to keep it semi-dry and semi-wet. In rainy days, pay attention to shelter from rain and drainage to prevent excessive accumulation in the basin.
Too much water leads to rotten roots. It is not advisable to water too much in winter, otherwise it will easily lead to defoliation or even waterlogging. The watering rule is generally "if you don't do it, you must water it thoroughly". exist
Fertilization in spring is to apply 1 time fully decomposed cake every 10 day when osmanthus trees germinate to promote their branches. After July, it was changed to liquid fertilizer based on phosphate fertilizer.
Promote flower bud differentiation of osmanthus fragrans. If fertilization is not enough, especially phosphorus fertilizer is not enough, it will lead to less branches, less flowers and less fragrance. You can use the soil in the basin before entering the house in winter.
Sprinkle bean cake powder on the surface or pour thick fertilizer for the winter. Osmanthus fragrans has a well-developed root system and needs pruning, so it will germinate vigorously. Therefore, it takes time to make osmanthus trees flourish every once in a while.
Prune properly to keep the balance between reproductive growth and nutritional growth. Generally speaking, long branches, twigs and branches of diseases and pests should be cut off, which is beneficial to ventilation, nutrient concentration and growth of osmanthus trees.
Osmanthus trees grow more and fuller buds, and the flowers are more fragrant.
Question 9: Is it good to transplant osmanthus trees? What should I pay attention to when planting? When is the best time to transplant osmanthus trees? The best planting season of osmanthus fragrans is around the sprouting of new branches every year and after flowering in autumn, that is,1-May and1-65438+February every year. The best transplanting time of big trees is1from mid-October to early February. At this time, the trees are dormant, and soon after transplantation, their activity becomes stronger and they are easy to survive. Avoid transplanting in summer. If you really want to transplant in the hot and dry season, you must increase the corresponding shading facilities after transplanting and increase the number of times you spray water on the branches and leaves every day. The key to the survival of osmanthus fragrans transplantation is water. Therefore, everything in Osmanthus fragrans transplantation should be carried out around the required conditions. The planting hole is 0.4m× 0.4m× 0.4m, and 2-3kg of farm manure (pig manure and cow dung) and 0.5kg of phosphate fertilizer are applied to each hole as base fertilizer.

Question 10: What should I pay attention to when buying osmanthus trees? Now the osmanthus seedling market has the following performances: the number of large seedlings is small and the price is high; Small seedlings flood the market and the price is low; It is difficult to find high-quality seedlings with good shape and guaranteed survival rate; Inferior seedlings with unsatisfactory shape and poor stability abound. After years of investigation, the author thinks that the price composition of osmanthus fragrans seedlings should depend on three factors: size, propagation mode and variety brand effect.
First, variety selection:
Osmanthus fragrans varieties are divided into Jingui (yellow), Yin Gui (white), Dangui (red) and Sijigui (yellow). Choosing a good osmanthus variety is the primary task of purchasing seedlings. Many landscape engineers buy some low-priced inferior seedlings (including no flowering or few flowers, low survival rate, invalid crown when seedlings grow up, and easy to cause pests and diseases) to do projects. I hate it very much. However, the public did not appreciate the report on the flowering of osmanthus fragrans, saying that it was caused by fresh cultivation or lack of nutrition and climate. In some places, this may be true, but in some places, the report is really incredible. Here is a reminder: when buying seedlings, please pay attention to seed seedlings and cutting seedlings. Seed seedlings are generally beautiful, with straight trunk diameter, but few capillary roots, which are easy to die after transplanting. It is suggested to buy transplanted seed seedlings, which generally bloom for more than 10 years (about 10 cm). The fragrance of flowers is not as good as that of cuttings, and the price is only half of that of cuttings. Please don't blindly pursue the price and tree shape of engineering seedlings, but pay attention to the quality of seedling varieties.
I would like to remind you that the weather in the north is generally cold, which is suitable for the growth of osmanthus fragrans, but the growth rate is relatively slow. Basically, any variety can be planted in the south. If you want to grow faster, it is recommended to buy fast-growing osmanthus, generally buy Xianning Liusugui modeling and flower picking.
Second, the price mystery:
Price can be said to be the first measure for most people to buy seedlings. Everyone sells at a different price in every place. There is no uniform standard. The price gap between cutting seedlings and seed seedlings is relatively large. Many people have cheaper seedlings, which may be seed seedlings. The stage of seed seedling is generally half that of cutting seedling. Generally speaking, the prices of Jingui and Yin Gui are similar. Yin Gui over 12cm is slightly higher than Jingui, and the seedlings of Sijigui below 6 cm are cheaper than Jingui and Yin Gui. The price of osmanthus fragrans over 18cm is higher than Jingui and Yin Gui. The price of Osmanthus fragrans is generally about three times that of Jingui, Yin Gui and Sijigui (Osmanthus fragrans grows slowly, usually only one centimeter in three years). Many people get big osmanthus by grafting. Please be sure to note that the grafted seedlings are not tall and have a faint fragrance!
Reminder: Many quotations are false. How to identify them?
For example: 15cm Jingui, the quotation can be 2400 or 5000 or 6000 or 7500, which is very different.
When buying a tree, you should know the starting position of the tree, whether it is the ground diameter, the meter diameter or the breast diameter. In most areas, the size of trees is measured according to the diameter of meters above 65,438+00 cm. If the ground diameter is 15cm, then the meter longitude is about 12cm, which is naturally 2400 according to the current market price. Also refer to the branch height and crown size of the tree, such as 15 cm, and the crown size is generally above 3 m and below 4.5. The price of trees with 3 m crown is around 5000, and the price of trees with 4.5 crown is around 6000. If it branches above 1.5, the current price is around 7000-75000. (The above prices are for digging, getting on the bus and going through formalities. Many people quote the land price, please consult clearly. )
Many customers called to inquire about the price and found that the price was very different, but after they went, they found it was completely different. Therefore, we must be clear about the following points: the position of the oversized tree, the size of the crown, the height of the branch point, and whether it includes the price of digging, getting on the bus and getting a permit.
Third, the transaction process:
When buying seedlings, don't listen to one person's one-sided words. You should look around more. Generally, the prices of seedlings in the five major producing areas of osmanthus fragrans are relatively cheap. Check the nursery before buying (please don't look at the photos to set up trees, many people have been cheated). If you are looking for a local agent to buy, you can only put a small deposit first, and then pay after all the seedlings get on the bus and go through the formalities.
The process is generally as follows: (1) Investigate the seedlings in the base-> Pay a small deposit in advance-> Do a good job in loading procedures (generally including seedling pre-inspection certificate and seedling transportation certificate)-pay the balance.
If you are not at ease, you can ask the other party to escort the transport vehicle to the expressway or follow the vehicle to the destination. > & gt
