Shade cultivation is the most advanced premise for the cultivation of Hanlan, and also an important condition to ensure that its leaves are glossy, oil-green and have few diseases. Most of the Wild Cymbidium grows in the dense broad-leaved forest, under the mixed forest, the shade is very high.
The domesticated Hanlan should try to imitate its original ecological environment, and the shading should be doubled, especially in the high temperature season with strong illumination, the shading must be more than 80%. If you raise orchids on the Nanyang platform with good lighting, you should try your best to put them in the place where there is little sunshine. You'd better put them on the lower part of the fence so that other plants can block the light. It will have a good effect.
The place where the Wild Cymbidium grows is full of fog all the year round, and the humidity is very high, so it is difficult to find its trace in a little dry place facing the sun. Therefore, it is very important to keep the humidity of environment when raising Hanlan at home. Many orchid friends raise Hanlan together with Chunlan and Huilan. In fact, the humidity suitable for Chunlan and Huilan is not enough for Hanlan. The humidity of Hanlan's room is about 10% higher than that of his substitute, which can reach 40% - 70% in the daytime and 80% at night. Be careful to keep the ventilation.
Because of the different varieties of Hanlan, pseudobulbs are big and small. The nutrients stored in the small pseudobulbous Cymbidium are limited, and it is easy to bloom, and the flowers are large, which leads to more nutrient consumption. Therefore, fertilization must be important.
Its low reproduction rate and slow seedling growth is one of the difficulties in the cultivation of cold orchid. It's not easy to get down the mountain to grow seedlings. The new ones haven't grown up yet, and the old ones have fallen down. Because the cold orchid is more frequent and has a longer flowering period, it consumes too much nutrients, so the old seedlings are unable to germinate more when maintaining their own nutrients, which makes it difficult to increase seedlings.
As a matter of fact, Hanlan has strong plants and developed roots. If new seedlings have already been established, they can be propagated by single seedling, or even cut and replanted by old leafless people. Usually in August, the seedlings are divided. At this time, it is beneficial to inhibit the formation of germination, reduce the consumption of nutrients, and improve their ability of independent survival.
Through the comparison of multiple plant ingredients, it is found that the best way to cultivate Hanlan is to use mixed plant ingredients, and no matter what kind of granular plant ingredients are used, they should be mixed with some mountain mud or humus soil, so the growth of Hanlan is the best.
