Answer: Cause: 1 The temperature is low, humidity is too high, and ventilation is poor. Under low temperature conditions, the ventilation is poor, the humidity in the mushroom shed is high, the evaporation is small, and the surface of the cap has a long-term accumulation of a water film. 2 sudden changes in temperature, temperature difference is too large. The high temperature during the day and the sudden drop in temperature during the night caused the temperature difference between day and night to exceed 10°C.
Prevention methods: 1 warming and heat preservation. During the cold season, when the temperature in the shed is too low at night, warming measures should be taken to facilitate the normal growth of Pleurotus ostreatus fruiting bodies. At the same time, pay attention to strengthening the insulation measures to reduce the heat loss of the mushroom shed and try to avoid the stimulation of fruit bodies at low temperatures. 2 reduce the amount of water spray, pay attention to ventilation after spraying. In the cold season, do not spray heavy water. Spray water only once a day. Ventilate the water after spraying to avoid accumulation of stagnant water.
