Symptoms of Pleurotus ostreatus

Symptoms: mushroom stalk tissue is not full, there is a white loose pulp inside, the pulp shrinks or falls off into a hollow shape after drying or cooking.

The cause is mainly due to improper water management. if the air humidity of the mushroom room is low, the soil layer humidity is low, especially the water content of the coarse soil layer is insufficient, the rapidly growing fruiting body will not be able to get sufficient water from the soil layer. furthermore, the transport and supply of nutrients will be reduced, coupled with the continuous evaporation of water in the mushroom body, which will result in a lack of water in the middle of the stalk and a lack of tissue, resulting in the phenomenon of hollow roots.

Preventive measures: 1. When transferring water from coarse soil and spraying mushroom water and mushroom water, the amount of water should be sufficient to prevent false wetness of soil particles. 2. Spray mushroom water once after mushroom emergence to ensure that the coarse soil layer can be replenished continuously during the whole peak period of mushroom production. 3. In the stage of growing mushrooms, we should often spray and humidify the mushroom room, and the relative humidity of the air in the mushroom room should reach 90%. When the temperature is high, it should be ventilated in the morning and evening or at night to prevent the loss of water too quickly.
