Pleurotus ostreatus is an edible fungus with easy cultivation, high yield and high added value, which is increasingly loved by urban and rural residents. Usually Pleurotus ostreatus is cultivated in autumn, winter and spring. In summer with high temperature and humidity, Pleurotus ostreatus is prone to diseases and pests, and few people cultivate it, which leads to insufficient supply of Pleurotus ostreatus and insufficient market supply, so the price is relatively high, which is 3-5 times that of the conventional cultivation season.
