How to prevent agaricus bisporus strain degradation

Preventing the degradation of bacteria can increase the yield, reduce the occurrence and development of diseases and insect pests and reduce the amount of pesticides, which is the basis of the production of organic Pleurotus ostreatus. 1. The ambient temperature of cultured bacteria should not exceed 28 degrees, and the storage time of cultured bacteria at room temperature should not exceed half a month. two。 It is necessary to grasp the time and temperature of the culture medium to prevent the destruction of nutrients and the pH should be appropriate. 3. The culture medium should be changed frequently, such as wheat straw or rice straw, chicken dung, cottonseed hull, wheat bran and other medium materials should be used alternately. 4. Don't use up the original seed at once, take it in stages, and keep the rest at low temperature to prevent too many generations. 5. The fruiting bodies with large individuals, normal growth and strong disease-free insects should be selected for tissue separation once a year, and the good and bad should be selected to expand the inoculation growth.
