The reason is that the C/N ratio of 1 culture medium is out of balance, and the N element in the culture medium is too high, mainly because too many N sources such as bran or urea are added to the culture medium.
2 the ph value is too low.
The culture temperature is relatively high.
Prevention and control methods: The C/N ratio of the culture material must be controlled at 15-20: 1 at high temperature, and N nutrition cannot be excessively added. The PH value can be appropriately raised to 8, and the temperature can be effectively lowered by various methods to create an environment suitable for Coprinus comatus.
For Coprinus comatus, it can be pulled out in time when Coprinus comatus is young and tender, and the culture temperature can be reduced, which can effectively prevent Coprinus comatus from recurring.
