How to prevent spawn degeneration in button mushrooms? Please provide methods
Preventing spawn degeneration in button mushrooms can increase yield, reduce the occurrence and development of pests and diseases, and reduce pesticide use. It is the foundation of organic button mushroom production. The following methods can be used for prevention:
1. The ambient temperature for culturing spawn must not exceed 28°C, and properly cultured spawn should not be stored at room temperature for more than half a month.
2. Properly master the time and temperature for mycelium growth on the culture medium to prevent damage to nutrients, and the pH must be suitable.
3. The culture medium should be changed frequently; for example, culture medium materials such as wheat straw or rice straw, chicken manure, cottonseed hulls, and wheat bran should be used alternately.
4. Do not use up the stock culture all at once; take it in portions and store the remainder at low temperature to prevent excessive subculturing.
5. Each year, select one fruit body that is large, grows normally, is robust, and free of pests and diseases for tissue isolation, selecting the superior and eliminating the inferior, and expand inoculation and growth.
