From the name, it is easy to mistake the lotus for being planted in the water like a lotus. In fact, lotus is a potted plant, which is often used as a green plant in front of windowsills, balconies and lobbies. Let's take a look at the cultivation method of lotus.
Lotus is an evergreen plant that has been growing for many years. The base of the old stem is often lignified/the leaflike branches are lanceolate, the edges are sparsely sawn, and there are short thorns between the teeth. Single peanut is on both sides of the stem tip, with bell-shaped flowers, uncoiled perianth, twisted filaments and styles, and the colors are purple, red, pink, yellow and white. Flowering period: spring, summer, daytime, single flower 1~2 days. Mexico is the most earthy place, and China is dominated by potted plants. It is a close relative of Epiphyllum, so its flowering period is short. However, Lingjianlian has many varieties, rich colors and bright colors, which are more beautiful than Epiphyllum, so it is more beautiful. People love it. It blooms in midsummer and is a good ornament for windows, balconies and foyers.
Cultivation methods of Lanzhou lily;
1. Soil: Lingjianlian does not have particularly high requirements for soil, so loose and fertile sandy loam with good drainage can be used.
2. Watering: During the growth and development of Allium chinense, watering should be both wet and dry, and no water should be accumulated in the basin, otherwise the roots will rot easily. Don't water the buds too much when they are in full bloom, otherwise it will easily lead to falling flowers and buds. In dry and windy spring and hot summer, it is often necessary to spray abnormal stems with clear water and sprinkle water on the ground around the flowerpot to maintain high air humidity, which is conducive to growth and flowering.
3, sunshine: Ling Jianlian likes a warm and humid environment, but avoid direct sunlight. In summer, the weather is hot and the sun is strong. Should be placed under a shade shed, avoid direct sunlight, and often spray water around the basin to improve air humidity. The winter weather is cold, and the lotus is not cold-resistant, so it should be placed in a sunny place after entering the room.
4. Temperature: Lingjianlian is not cold-resistant. The northern area should enter the room around the cold dew festival and put it in a sunny place after entering the room. From June 1 1 to March of the following year, the temperature shall be kept at 10- 15℃. If the temperature is too high, the deformed stem will grow white and affect the symmetry of plant shape. The temperature should be kept at 13- 18℃ from March to June. Too low temperature will affect pregnancy.
5. Pruning: Because the abnormal stem of Lingjianlian is soft, it is necessary to use thin bamboo poles as pillars, and it is best to tie them into oval brackets. The deformed stems are evenly distributed on the bracket and bound, which can not only prevent them from breaking, but also facilitate ventilation and light transmission, making the plant shape symmetrical and beautiful.
6. Fertilization: Ling Jianlian likes fertilization. In the growing season, apply 1 time decomposed pancake fertilizer every 15-20 days. After the Spring Festival, liquid fertilizer should be applied every 10 day to wipe off excessive lateral buds and branch buds sprouting at the base in time, reduce nutrient consumption and keep the plant shape neat and beautiful. Apply 1-2 times of available phosphorus fertilizer in bud stage to promote large flowers and bright colors.
7. Insect pests: Lily in Lanzhou often suffers from stem rot, brown spot and root-knot nematodiasis. The root-knot nematodiasis can be prevented by spraying 50% carbendazim wettable powder 1000 times and irrigating 80% dibromochloropropane EC 1000 times. Poor ventilation, vulnerable to aphids, scale insects and red spiders, and can be sprayed with 1000 times 50% chlorpyrifos EC.
Lingjianlian is a common potted plant, which is used for home decoration. It has many varieties of colors, rich and bright colors, but short flowering period. However, as long as it is carefully matched, the spirit sword lotus can also add a lot of color to the family.
Matters needing attention in aquaculture:
spring
In the growing season of lotus, we should pay attention to adequate illumination and timely fertilization, and apply nitrogen and phosphorus fertilizer every 10- 15 days to promote the robust growth of flowers and leaves. Avoid water accumulation in the basin and prevent root rot. From April, buds appeared on the edge of fleshy upper leaves, and gradually expanded and blossomed after half a month. If plants are malnourished and weak at this time, they will not bloom or bloom less. In order to prevent this phenomenon, 1-2 quick-acting phosphate fertilizer can be applied in advance. At the same time, too many lateral buds and branch buds at the base should also be wiped off.
summer
In the vigorous growth period, nitrogen fertilizer should be applied 1-2 times in time. This will not only promote it to grow new branches and leaves, but also help it to grow more buds and flowers next spring. If you want to increase the number of stems, you must seize this favorable period to leave buds. When it is hot in midsummer, the lotus enters the semi-dormancy period and should be placed in a ventilated and cool semi-shady place. Stop fertilizing, water too much, keep the pot soil slightly dry, to prevent too much shade, so as not to affect flowering in vain.
autumn
It is the second vigorous growth period in a year, and the new leaves gradually age and mature. The method of management and maintenance is basically the same as that in May and June in spring and early summer, and topdressing is enough for 2-3 times, mainly phosphorus and potassium fertilizers. And the illumination time is increased.
winter
The weather turns cold after the first frost, so it needs to be moved indoors to keep warm. It can be placed in a sunny place indoors, and the room temperature can be kept at 8℃. Stop fertilizing and save water. The soil in the basin had better be dry. Too much humidity will cause the leaves to wither and rot. From mid-March to early April after beginning of spring, with the increase of temperature, the time of window opening and ventilation can be gradually extended, laying a foundation for outdoor maintenance in the future.
Extension: When will the lotus blossom?
The lotus period of Lingjian usually blooms in spring, summer and daytime, with single flower 1~2 days.
Lingjianlian likes warm and humid environment, avoids direct sunlight, is drought-resistant, semi-cloudy and rainproof, and requires fertile, loose and well-drained neutral or slightly acidic sandy loam. The optimum temperature for growth period is 20-25℃, the optimum temperature for flower bud differentiation is between 10- 15℃, the temperature in winter should not be lower than 5℃, and the flowering period is April.
In summer, the weather is hot and the sun is strong, so it should be placed under a shade shed to avoid direct sunlight, and water should be sprayed frequently around the basin to improve the air humidity. It should be moved indoors before the first frost in winter. When the temperature is above 5℃, it is safe to overwinter. In March, the plants should be moved to the sun, and the temperature should be kept at 10- 15℃ to promote flower bud differentiation. When flower buds are formed, if they are too dense, they should be properly thinned.
Lingjianlian is drought-resistant, so the pot soil should not be too wet. During the bud formation period from March to April, it is necessary to water and fertilize more. Phosphate fertilizer can be applied once to make it accumulate nutrients, with more buds and flowers, but the pot soil should not be too wet. May to July is the flowering season. At this time, we should water less and not fertilize. Usually it can be watered once a week. After the flowers wither, it is advisable to dry the soil slightly. After entering the room in winter, water it according to the principle of "dry thoroughly and thoroughly", otherwise it will easily lead to rot.
Water lilies are changed once a year or two, usually every other year in spring and autumn. Sandy soil containing organic matter is suitable for basin soil. When changing pots, remove some old soil and rotten roots, supplement new culture soil (humus soil 4 points, garden soil 3 points, compost soil 2 points, sand soil 1 point), and add bone meal as base fertilizer. After changing pots, the flowers should be shaded and maintained, and then grown in the sun. Shading should be done in midsummer to avoid damage caused by excessive light intensity, and leaves should be moved indoors in rainy days. After beginning of autumn, you can fully see the light, otherwise the light is insufficient and it is not easy to bloom.
