Preventing the degradation of strains can increase the yield, reduce the occurrence and development of pests and diseases, and reduce the amount of pesticides used. It is the basis for producing organic Agaricus bisporus.
1. The environmental temperature of cultured strains should not exceed 28 degrees, and the cultured strains should not be stored for more than two weeks at room temperature.
2. Effectively grasp the time and temperature of the culture medium to prevent bacteria from destroying nutrients, and the pH should be appropriate.
3. Always change the medium, such as wheat straw or straw, chicken manure, cottonseed hulls, wheat bran and other medium materials to be used interchangeably.
4. The original species should not be used up once, and be used in batches. The remaining cryopreservation should prevent excessive passage.
5. Each year should choose a large individual, normal growth, robust pest-free fruiting body for a tissue separation, from which to choose superior and inferior, expand the growth of inoculation.
