Remedial measures and methods for problems encountered in the growth of mushrooms

The main results are as follows: (1) the mycelium can not grow on the soil layer mainly because the culture material is overcooked or partial, or the pH value of the culture material and soil cover is improper, or because of spraying too much water into the material layer, the mycelium shrinks or dies. In cultivation, measures should be taken to strengthen ventilation, adjust ph value and excessive moisture emitted by cuttings in materials to remedy.

(2) the mushroom buds turn yellow or die due to too high temperature and humidity. In management, measures such as strengthening ventilation, stopping water spraying and lowering room temperature are used to reduce dead mushrooms.

(3) Pleurotus ostreatus is mainly due to the fact that the culture material is too thin or too dry, or the soil cover is too thin, the mycelium is exposed to fine soil and poor management, resulting in weak mycelium life, dense mushroom production, small mushroom body and poor quality. Therefore, measures such as topdressing and replenishing soil and maintaining normal temperature should be taken to prevent dense mushrooms.

(4) due to the decrease of temperature or the excessive temperature difference between day and night, the air is dry, or the culture material is too wet, the mycelium life is weak, so the immature fruiting body is easy to produce hard opening, and heat preservation and increasing air humidity are often used to prevent the occurrence of hard opening.

(5) some deformed mushrooms often appear because of thick soil cover, too large soil particles, too late fine soil cover, too high humidity, poor ventilation and so on. The main preventive measures are that the size of soil particles should be appropriate, the soil cover should be timely, and the soil layer should not be too thick, followed by strengthening the management of moisture and ventilation.

(6) when the air temperature is high, the water supply is insufficient and the temperature is low, the mushroom grows slowly and stays in the mushroom bed for too long, the hollow phenomenon will occur. It is mainly prevented by strengthening temperature and water management.
