The influence of Air humidity on National Orchid

Although the national orchid belongs to the terrestrial orchid plant, its thick and fat fleshy root makes it still have some properties of aerial orchid. In the process of cultivation, the higher air temperature is an important factor for successful cultivation. In particular, the rough-skinned orchid, which is more popular in recent years, the high humid air can not only fully express its new generation of art, but also improve its efficiency. It is observed that about 80% humidity is the best for the growth of the national orchid. If the air temperature is too high, it is easy to cause poor resistance of seedlings and weak seedlings and become infected with diseases and insect pests, especially in greenhouse cultivation, we should pay more attention to timely ventilation and control air humidity.
