Hanlan is suitable for planting humic soil with little light, shallow foundation and a thin layer of root covering, with good water permeability. Therefore, when choosing the high pots for planting, 1/3 of the bottom of the basin is coarse grained bricks and foamed plastic blocks, and the middle part is mixed with red soil brick and sand to the basin 1/3. The upper part is mixed with small grains of sand and small amount of humic soil. Planting requires looseness, air permeability and water utilization.
Because the growth environment of Hanlan is different from other orchids, the cultivation methods should be slightly different.
Shading degree and temperature, especially in high temperature season with strong illumination, should pay more attention to shading and moisturizing. Hanlan native forest dense, there are tall trees for them to block the sun and shade. Therefore, we should create suitable lighting conditions for the cultivation of Hanlan artificially. Too much light can cause sunburn of leaves. Excessive shading or long-term indoor storage will affect the photosynthesis of orchids, resulting in poor growth and not easy to bloom. In addition, foliar water should be sprayed in the morning or evening every sunny day, with the shading degree of about 80%. This leaves luster, less disease. In a word, under the premise of ensuring that the orchid leaves are not burned, there should be more sunlight.
In autumn and winter, avoid strong wind, and cover the frosty days to keep warm.
In general, Hanlan can use less fertilizer, or even no fertilizer. Most of Hanlan consume more nutrients because of its relatively small pseudobulbs and limited storage of nutrients. In addition, it is easy to bloom and has many large scape flowers. Therefore, it is better to add a small amount of basal fertilizer when cultivating the strong seedlings of Hanlan ripe grass. But the grass should not be fertilized and sprayed in a hurry, otherwise it will suffer from fertilizer and drug damage. In addition, potassium dihydrogen phosphate and cyanobacteria can be used alternately as foliar fertilization, once every seven to ten days, and a certain amount of urea can be added in the growth period of new shoots, and then two to three times of high potassium fertilizer can be sprayed in the mature period of new seedlings to promote the growth of pseudobulbs. In order to make all kinds of nutrients more balanced, thin organic fertilizer can be applied once a month from April to June and September to October, but it should be remembered that it is better to be light than to be thick to prevent fertilizer damage.
