After several years of planting, the ornamental value of the Brazilian iron pillar is reduced because the plant is too large or the leaves at the lower part of the stem fall off.
The stem can be cut about 10 cm above the pot surface, and then cut into a section of 5~ 10 cm as a cutting.
Wooden barrels or large flowerpots can be filled with coarse sand or vermiculite to make a simple bed insertion.
Insert the cuttings of 1/3~ 1/2 vertically into the sand;
Or lie all cuttings in coarse sand in a semi-recumbent way, and expose them to the sand surface for about 1~2 cm. You can also soak about 1/3 of the lower part of the cuttings in water.
Spray water frequently to keep the high humidity of the trough bed;
The temperature of 2 1~24℃ is favorable for cuttings to take root and germinate. The top with leaves takes root quickly and can take root in potted plants in 3~4 weeks.
Stem segments take root slowly, sometimes it takes 2~3 months.
The mother plant with its stem cut off can have several hidden buds to grow new branches under the incision.
When the bud is higher than 15cm, cut off the cuttings and take root in potted plants in 2-3 weeks.
Inserting leaves is to take complete leaves and insert them into sterilized matrix. The same management can take root in about two months. After transplanting, about 40 days later, new buds will sprout at the junction of roots and leaves and grow into independent plants. As long as the temperature and other conditions are suitable, Brazilian wood can grow all year round.
Proper shading is needed when it is hot in summer, and the room temperature should not be lower than 5℃ in winter.
But it is best to hibernate in winter, and the dormancy temperature is 65438 03℃. If the temperature is too low, chloasma will appear on the tips and edges of leaves.
Basswood should be placed in a well-lit place indoors.
If the light money is too weak, the markings on the leaves will turn green and the basal leaves will turn yellow, losing their ornamental value.
During cultivation, the water quality should be kept clean, and it should be watered 1 ~ 2 times a week, so as to prevent the trunk from rotting.
When it is hot in summer, you can improve the air humidity by spraying, and spray water on the leaves to keep it moist.
Brazilian wood likes high temperature, humidity and plenty of sunshine, but if it is too dark, the leaves will fade.
Semi-shading is needed in summer to avoid alkaline soil.
Potted soil should be humus soil or peat soil, about 1/4 river sand or perlite, and a small amount of decomposed organic fertilizer.
The soil is loose, well drained and rich in organic matter, which is beneficial to its growth.
During the growing period, dilute fertilizer solution mainly containing phosphorus and potassium should be applied once every half month to prevent plants from growing white and leaves from turning green.
Change pots and soil in early spring every year, and apply sufficient base fertilizer.
Brazilian iron column has strong adaptability and drought resistance, and it will not die if it is not watered for a few days.
But in order to grow well, there must be sufficient water supply.
Especially in the summer when the growth is vigorous, we can't lack water. Flower pots can grow all year round if they are placed in a room with suitable temperature, sufficient water and fertilizer and sufficient sunshine.
Only when the temperature is lower than 13℃, plants will sleep and stop growing. At this time, watering should be reduced, and topdressing should be stopped when dry and wet alternate.
Low temperature is the main cause of defoliation in winter.
Irregular watering, insufficient nutrient supply, dry indoor air, or large amount of fertilization are all physiological diseases that lead to leaf tip scorching. Dead leaves appear and should be treated separately.
If the supply of water and fertilizer is insufficient, water can be sprayed 2-3 times a day, once a week 1 time, and 0. 1% ammonium sulfate or potassium dihydrogen phosphate solution is used, and sometimes it is removed to irradiate the morning sun.
When the weather is warm, use big pots, change new soil and replant them, so that Dozza Baigen can continue to grow sturdily in the future.
If it is excessive fertilization, it should be replaced with new soil immediately, and the roots should be washed with water with similar temperature, and then replanted.
Brazilian iron columns are resistant to pruning. As long as the top or upper stem is cut off, the hidden buds under the incision will grow new branches and leaves. 1~5 buds can sprout at the same time and then grow into one plant. Temperature and light
The optimum growth temperature is 20 ~ 28℃, dormancy temperature is 65438 03℃, and overwintering temperature is 5℃.
If the temperature is too low, chloasma will appear at the tip and edge of the leaves, and in severe cases, the shoots or the whole plant will be frozen. Therefore, it is necessary to move into a greenhouse for maintenance in the northern winter.
If it is placed indoors, it should be placed in a sunny place, and the room temperature should be kept above 6℃ to 8℃.
When the temperature is low at night, you can put on a plastic bag to keep warm. When the sun comes out during the day and the room temperature rises, it is necessary to take down the plastic bag in time to cool down and prevent suffocation.
If there is heating equipment indoors, put the basin far away to prevent drying or drying the branches and leaves. Also pay attention to the indoor air flow, but when opening the doors and windows, don't let the cold wind blow directly on the branches and leaves, and don't move outdoors to bask in the sun at will to prevent freezing.
Brazilian wood has a wide range of adaptability to light, but it is not resistant to strong light. Especially from May to 10, the leaves turn yellow or the tip is scorched due to strong light notes. Pay attention to shading and give bright scattered light. Although it is tolerant to shade, too much shading will make the leaf color dim, especially for variegated varieties, and the markings on the leaves are easy to disappear, which reduces the ornamental value.
Moisture and humidity
Brazilian wood needs less water, but requires high humidity.
After the basin is lifted, water the foot root and place it in a bright room or a cool shed for maintenance.
The basin soil should be kept moist, and the leaves should be sprayed with water frequently to improve the air humidity of the surrounding environment, but the basin soil should not accumulate water to avoid root rot caused by poor ventilation.
Wood in northern Brazil should be maintained in spring, summer and autumn during its growth. Water 1 time every 2 ~ 3 days in sunny days, and water 1 ~ 2 times per day is appropriate for the leaves.
After the end of autumn, it is advisable to control the amount of watering and keep the basin soil slightly wet. Water should be controlled in winter, and the basin soil should be kept half dry and half wet. If it is drenched too much, the roots and leaves will rot.
Soil and fertilizer
Brazilian wood is suitable for loose, well-drained and humus-rich fertile river sand loam.
Potted Brazilian wood can be mixed with garden soil, humus soil, peat soil and river sand in the ratio of 3:2:2:3, or the fertile pond mud can be dried in the sun and finely ground by 2/3, and the coarse river sand 1/3.
If thick stems are selected for planting, the culture soil can be made of vermiculite, peat soil or garden soil mixed with river sand. Brazilian potted wood in the market is mostly fine sand, which is used by producers to make plants take root fully. Long-term use will be harmful to plant growth. In order for plants to thrive, peat soil must be replaced in stages. In addition, Brazilian wood should be changed once a year. When changing pots, replace the old soil with 1/3, and then replace it with new silt soil, and trim the aged scorched leaves on the leaf stems and the lower parts of the stems.
Brazil wood needs to consume some of its own nutrients during its growth. If it is not fertilized in time, it will cause insufficient stamina and gradually degenerate.
During the growth period, organic fertilizer should be buried at the base or edge first, and then liquid fertilizer or compound fertilizer should be applied12 times every 15 ~ 20 days to ensure the flourishing growth of branches and leaves.
Thin fertilizer should be applied instead of thick fertilizer, and the fertilization period is from May to 10 every year. Stop fertilizing in winter and move indoors for the winter. For striped varieties, attention should be paid to reducing the proportion of nitrogen fertilizer when fertilizing, so as not to cause the white leaves to grow, leading to the darkening or even disappearance of stripes. The propagation of Brazilian wood is mainly cutting. The specific method is to coat paraffin or paint on the upper end of the cut stem segment to prevent water evaporation and water rot.
The lower end is inserted into the water for 2.3 cm, and the water and container are always kept clean; Or insert the lower end into the washed coarse sand, keep moisture and shade at a temperature above 25℃, and take root in about one month. ..
Brazilian wood is usually planted in flowerpots, and one or two roots are scattered in high places for decorative purposes.
As long as the temperature and other conditions are suitable, it can grow all year round.
But it is best to let it sleep in winter; The dormancy temperature is 65438 0 3℃; When the temperature is too low, chloasma will appear at the tip and edge of the leaf, which should not be lower than 5℃ in winter. Brazilian wood should stay away from direct bright light and wind, especially in summer, otherwise its leaves will be burnt.
But too cool environment will cause the leaves to turn yellow and fade.
Potted soil should maintain a certain humidity, and excessive humidity will affect plant growth. In the dry north, we should often spray water on leaves and surrounding environment to improve air humidity and create a humid climate. Brazilian wood has a large proportion of sand, especially for newly purchased plants. The basin soil is mostly coarse sand at the bottom, and the nutrient supply is insufficient. During the growing period, urea or potassium dihydrogen phosphate solution can be sprayed once a week. Fertilization should be stopped when the room temperature is lower than 65438 03℃.
Brazilian woody plants are generally clean and not easy to attract pests. However, if the environment is not suitable, there will be scale insects, thrips and red spiders, so we should always keep the leaves clean, properly ventilate and improve the small environment. Once pests occur, they should be removed in time and sprayed with tobacco leaf extract several times. Brazilian wood leaves sometimes suffer from edge scorching and tip withering, which are mostly physiological diseases caused by drought, low temperature, improper watering and fertilization or excessive ventilation. As long as the suitable growth environment is created according to the growth characteristics of Brazilian wood, Brazilian wood can take root deeply and grow healthily. Brazilian wood sometimes has dead leaves and dead shoots, which are mostly physiological diseases caused by drought, low temperature and improper watering and fertilization. The control methods are: strengthening cultivation management, controlling temperature and humidity, rational fertilization and proper ventilation.
Brazilian wood should always keep its leaves clean, and remove the insect body in time when it encounters pests. The sugarcane borer is harmful to Brazilian wood, so it can be moved to the outdoor shade and sprayed with 40% omethoate EC 1000 times or 90% trichlorfon/kloc-0 times a week, three times in a row.
70% thiophanate-methyl wettable powder 1000 times solution can spray common leaf spot and anthracnose. Insects are harmful to scale insects and aphids, and 40% omethoate EC 1000 times can be sprayed.
Feng Shui Function of Brazilian Wood
1, basmu has a positive effect on family feng shui with south gate. The gate in the south belongs to fire, so we should plant plants belonging to fire and plant dragon blood tree to increase the positive energy of fire. At this time, the dragon blood tree can be placed at the entrance of the living room, the corner of the hall or next to the stairs, which is conducive to regulating the health of people's heart and stomach, and also has a regulating effect on some people's negative personalities such as introversion, timidity, lack of courage and lack of confidence in life.
2. From the perspective of geomantic omen, it is beneficial to the development of family members. The geomantic omen in the living room is related to the harmony of the family, to the cultivation of interpersonal context, and will eventually affect the fortune and prospects of the family. Small and medium-sized potted plants or flower arrangements are usually the main methods to avoid large potted plants, so as not to attract mosquitoes and feel oppressive. Special festivals can be arranged simply. Families who are busy at work on weekdays can choose green foliage plants to relieve stress, and holidays can be decorated with colorful flowers and leaves. It's just right to put two dragon blood trees here.
