In the case of poor ventilation, the stems of the mushrooms are longer and serious pests and diseases occur. Therefore, the ventilation of the mushroom greenhouse must be good . Shiitake mushrooms are a kind of temperature-changing fungi. Because Shiitake mushrooms have different varieties of high-temperature, medium-temperature and low-temperature types, the requirements for fruiting temperature are different. The fruiting temperature range for low temperature type is 5-20 degrees, medium temperature type is 10-22 degrees, and high temperature type is 15-25 degrees. Humidity requirements for mushrooms: the budding stage is 80%-90%, the fruit body growth stage requires air relative humidity 70%-80%, less than 60%, the fruit body grows slowly, the cap is easy to crack, and it is easy to form under low temperature conditions.
