Pleurotus ostreatus is a medium-low temperature fungus, which, like Pleurotus ostreatus and Lentinus edodes, has the characteristics of changing temperature to produce mushrooms. The optimum temperature for mycelium growth is 24 ~ 26℃, the temperature range for fruiting body differentiation and development is 5 ~ 22℃, and the optimum temperature for fruiting is 10 ~ 18℃. Therefore, the suitable fruit-bearing time in southern China is 10 to March of the following year, and the fruit-bearing time in high-altitude mountainous areas can be advanced or postponed appropriately, and the altitude is 18. The northern region is cold in winter, so it is difficult for Agaricus blazei to produce mushrooms under natural conditions. Agaricus blazei cultivated under natural conditions usually produces mushrooms from the end of September to the beginning of 65438+February, and from the beginning of March to the end of April. Using solar greenhouse or underground mushroom shed, mushrooms can grow in the north all year round. Climate conditions vary from place to place, so the mushroom season will not be exactly the same. In production, the best local cultivation season should be determined according to the local climatic conditions and the growth characteristics of Pleurotus ostreatus.
