Mushrooms are used to indicate that the small mushroom on the mushroom bed has shrunk, yellowed, and died. Mushrooms withered in crops or in batches can seriously affect yield. 1. Causes of dead mushrooms: 1The temperature in late autumn is too high (over 23°C). During the springtime, the temperature rises too high and too fast (21°C for consecutive days), causing the mushroom seedlings to die and die due to lack of nutrition. 2 Poorly ventilated mushroom house, O2 insufficient CO2 concentration is too high, the heat generated by the metabolism can not be distributed quickly, will make small mushroom seedling died due to lack of oxygen supply or high temperature. 3 After casing, the mycelium grows too fast before mushrooming, resulting in too dense mushroom seedlings and inadequate nutrient supply, which causes some of the mushrooms to die. 4 The temperature is above 22°C, the relative humidity is above 95%, or the doors and windows are closed after water spray. The surface of the mycelia is stained with water, and the mushroom suffocates. 5 Inadvertent management operations resulted in mechanical damage caused by dead mushrooms. 6 The number of sprays is large and the quantity is large. Mushroom seedlings die due to phytotoxicity. 2. Control methods: 1 According to the local climatic conditions, arrange the inoculation time to avoid the mushrooming in the hot season. 2 Note that the mushroom house cools down to prevent high temperature attack. 3 To prevent the mycelium from growing out of the soil during the soil-filling stage, lower the part of the mushroom and avoid excessive density. 4 During the high temperature period, spray water to open the doors and windows, the material layer of water with bamboo stick holes, improve ventilation. 5 When preventing and curing diseases and insect miscellaneous bacteria, do not use excessive amounts of drugs and avoid using drugs during fruiting.
