Cultivation methods and matters needing attention of Guanyin lotus
Guanyin lotus has peculiar leaf shape, clear and unique veins, more shade-tolerant, and more suitable for indoor layout. Can be arranged in windowsill, corner flower stand, coffee table, dining table, desk and other places with scattered light. Here is a detailed introduction to how to raise Guanyin lotus:
1. Soil selection for Guanyin lotus cultivation
Guanyin lotus has low requirements for soil, and fertile and loose sandy loam is suitable. Humus soil, coarse sand and vermiculite are mixed according to the ratio of 2: 1: 1, and a small amount of plant ash and bone meal are added as base fertilizer.
Second, the fertilization method of Guanyin lotus culture
In the spring and autumn growing season of Guanyin Lotus, apply 1 time decomposed dilute liquid fertilizer or low nitrogen, high phosphorus and potassium compound fertilizer every 10 day. Fat water should be light but not thick, too much will easily cause fat damage. The content of nitrogen fertilizer in compound fertilizer should not be too much, too much is easy to make plants grow white.
In the vigorous growth period of Guanyin lotus, according to the growth situation of Guanyin lotus, 1 ~ 2 times of dilute liquid fertilizer should be applied every month, and phosphorus and potassium fertilizer should be added to make the stems of Guanyin lotus stand upright and grow healthily, which is also beneficial to the growth and enrichment of underground tubers of Guanyin lotus and cold resistance in winter. Spraying foliar fertilizer once every half month, adding organic fertilizer or compound fertilizer containing nitrogen, phosphorus and potassium once every 1 ~ 2 months, and applying more nitrogen fertilizer can promote the beauty of leaf color. When fertilizing Guanyin lotus, use a small nozzle watering can to slowly irrigate along the mouth of the basin, and don't splash the fertilizer solution on the leaves, otherwise it will easily burn the leaves.
Third, the temperature requirements of Guanyin lotus culture
Guanyin lotus likes cold and can resist cold. Spring and autumn are the main growth periods, and summer and winter are the main dormancy periods. When the temperature is high in summer, it is easy to cause Guanyin lotus plants to rot due to sultry humidity. Therefore, proper shading, improved ventilation conditions and cooling measures should be taken to make the basin soil moderately dry. In winter, when the daytime temperature is above 15℃ and the nighttime temperature is above 5℃, Guanyin lotus can still grow and maintain normally. When the temperature is low, if watering can be controlled, it can also withstand the low temperature of 2℃.
The temperature below 20℃ is dormancy, and the overwintering temperature is generally above 65438 05℃. Below 10℃, the leaves will freeze and wither, so it is suitable to plant indoors in winter.
Fourth, the light requirements of Guanyin lotus culture
It should be sunny. It is best to put it outdoors in the sun, which needs plenty of sunshine during the growing period. If sunshine can be guaranteed, the plant shape will be compact, the leaves will be thick and full, and the leaves will be beautiful. Although it can grow normally in semi-shade, its ornamental value is greatly affected, and many varieties are prone to loose and not compact plant types. In summer, to avoid exposure to the hot sun, it is necessary to shade properly.
Guanyin lotus is very shade-tolerant, and it is suitable for growing in places where the shade scatters light. Avoid direct sunlight. Generally, summer and autumn should be shaded, otherwise the leaves will be rough and dark, and sometimes sunburn will occur, but it is better to get more sunshine in winter.
Five, the matters needing attention of Guanyin lotus culture
1, Guanyin lotus has a great demand for fertilizer, and it should be applied once every 10 ~ 15 days in the growing season. It is best to use organic fertilizer or ternary compound fertilizer alternately, and apply more nitrogen fertilizer in the growing season to promote the beautiful color of leaves.
2. The optimum growth temperature of Guanyin lotus is 20℃ ~ 26℃, and it will hibernate below 20℃. If the temperature is too low, it is easy to cause plant death. It grows vigorously in spring and summer and requires high air humidity. If you can sprinkle water or spray leaves on the ground, it will grow better. Guanyin lotus can overwinter naturally in tropical areas. In subtropical and temperate regions, due to the low temperature in winter, attention should be paid to keeping warm in the greenhouse, and water should be controlled in winter, as long as the leaves do not droop.
3. Guanyin lotus is planted more in spring, and the basin soil requires good drainage and humus soil or sandy loam rich in organic matter. Changing pots should be done in late winter and early spring.
4. Guanyin lotus is vulnerable to aphids, and 40% dimethoate or 50% malathion EC 1000 ~ 1500 times or 80% dichlorvos EC 1500 times can be sprayed.
5. Guanyin lotus grows well in a warm, humid and semi-cloudy environment. In summer and autumn, it should be placed in a cool place, such as reed curtain or tree shade, to avoid direct sunlight. Plant growth needs high air humidity, and humid climate conditions are conducive to plant growth and leaf wetting. If the environment is too dry, it is easy to cause the leaves to scorch and affect the beauty of plants. The relative temperature of air is 60% ~ 80%. When the temperature of Guanyin lotus is 65438 05℃, its growth stops and it goes into dormancy.
6. In the growth period from May to 10, Guanyin lotus should be fertilized once every 15 days, so it is safer to use weak fertilizer solution. In winter, we should keep sufficient light and good ventilation, strictly control watering, and the soil is slightly dry. Indoor cultivation in winter should prevent high temperature, sultry weather or poor ventilation to prevent pests and diseases. Stop fertilizing in winter.
