How can the problem of dead mushrooms be prevented in mushroom cultivation?

1. Prepare the compost scientifically and reasonably so that the carbon-to-nitrogen ratio reaches 28-30:1, and do a careful job of composting; 2. Select high-quality spawn, promptly discard aged and contaminated spawn, create conditions suitable for mycelial growth and development, and strictly prevent high-temperature cultivation; 3. During the fruiting period, pay close attention to weather changes, adjust the shed temperature according to the air temperature, strengthen ventilation and air exchange, and strictly prevent high-temperature conditions inside the shed; 4. Make sure the mushroom shed is ventilated and aired regularly (generally 2-3 times a day); when the temperature is high, ventilate in the early morning and evening or at night to keep the air fresh. 5. Water based on the mushrooms, and avoid drowning them with too much water; 6. After casing soil is applied, regulate the temperature reasonably, maintain suitable moisture in the soil layer, promote mycelial growth into the casing soil layer, and make it shift from vegetative growth to reproductive growth as quickly as possible, so that the fruiting bodies form between the coarse soil layer and the fine soil layer, and prevent them from forming too high or too low; 7. In production, adhere to the integrated control principle of "prevention first, chemicals as a supplement," prevent pests and diseases from being brought into the mushroom bed with the compost, eliminate sources of pests and diseases in the casing soil, thoroughly remove pathogenic bacteria and insect pests from the mushroom shed, and create environmental conditions suitable for mushroom growth; after pests and diseases occur, promptly remove diseased mushrooms and dead mushrooms, and use drugs for control to avoid spreading and expansion. 8. When picking mushrooms, the movements should be gentle and careful to avoid human injury.
