Mushroom pinheads wither during the fruiting period: how to prevent mass death

    During the fruiting period of mushrooms, if management is slightly improper, the pinheads will shrink, turn yellow and die. The main reasons are as follows:

Mushroom

    1. Sustained high temperature: If the air temperature during the fruiting stage of mushrooms is above 23°C for more than 3 consecutive days, the growth of the pinheads is inhibited by temperature, but this favors the growth and development of the mycelium, thereby causing reverse nutrient transport and ultimately causing the pinheads to die from lack of nutrients and water. Therefore, after fruiting begins, preparations against high temperature are still needed, such as building a shade shed on the south side, spraying water on the mushroom house roof, using ice blocks to lower the temperature, appropriately delaying composting, and avoiding high temperatures.

    2. Insufficient nutrients: The compost lacks sufficient nutrients, such as insufficient nitrogen sources in the compost, especially a lack of manure, an imbalanced carbon-to-nitrogen ratio, anaerobic fermentation during composting, thin and insufficient compost, and insufficient nutrients, or the nutrients in the autumn mushrooms have been exhausted, causing the spring mushrooms to fail. Therefore, high-quality compost, good fermentation, proper turning of the compost, and thick-layer cultivation are required to provide sufficient nutrients for mushrooms.

    3. Poor ventilation in the mushroom house or mushroom shed: A poor mushroom house is stuffy, and long-term poor ventilation, especially during the fruiting period when the fruiting bodies have vigorous metabolism, can cause mass death of mushrooms if windows are closed for water adjustment, resulting in high temperature and high humidity.

    4. Improper water management: Mushrooms have different water requirements at different growth and development stages. Lack of water in the mycelium layer and insufficient water in the casing soil layer will both cause the death of young pinheads, or unclean water and long-term spraying of excessive water can also cause mushroom death.

    5. Too high osmotic pressure: Using salt water multiple times will increase osmotic pressure, causing the pinheads to lose water and die.

    6. Pest infestation and damage: In severe cases, pests eat all the mycelium, causing pinheads to die in batches.

    7. Abuse of pesticides: If pesticides are used during the fruiting period of mushrooms, they must be diluted as required. Arbitrarily increasing the pesticide concentration will cause pesticide damage to mushrooms. Pesticides containing petrochemical emulsifiers are prohibited.
