Tremella planting: how to control miscellaneous bacteria in Tremella?

How does Tremella prevent and cure miscellaneous bacteria? Please introduce the method of planting Tremella fuciformis is vulnerable to green mold, there are also some Rhizopus, Mucor and a few Alternaria. Green mold, Mucor and Rhizopus often occur next to the inoculation hole of the bacterial bag, or when the joint of the two colonies occurs 9-10 days after inoculation, it appears in the front of the hyphae and in the bag wall. Green mold also occurs on the fruiting body, making the ear pieces mildew. Alternaria often occurs at the seams at the mouth of the bag. The main causes of miscellaneous bacteria pollution are incomplete sterilization of material bags, not strict aseptic operation, perforation of bag membrane, impure bacteria or environmental pollution, etc. The prevention and control methods of Tremella fuciformis can be listed as follows: 1. Purify the environment of mushroom room: clean the environment regularly and disinfect it with lime powder. Before cultivation, the mushroom house should be strictly disinfected and sterilized to put an end to pollution sources. 2. Select raw and auxiliary materials: cottonseed hull and wheat bran are required to be free of caking, mildew and deterioration, and sterilized by exposure to the hot sun. The quality of the cultivation bag was tested in advance. 3. Standardize the production of bacterial bags: the water content of the culture material should not exceed 60%, and the time limit for bagging the stove should not exceed 6 hours to prevent the material from becoming sour. Sterilization should be kept at 100 ℃ for 24 hours without cooling. 4. Adhere to aseptic operation: thoroughly disinfect and sterilize the inoculation room. Select qualified disinfectant, spray space, bed and site. 5. Selected strains: the cultivation of Tremella fuciformis in spring requires stronger ash hyphae to avoid ash removal at low temperature after inoculation, affecting long ears. 6. Pollution bag treatment: pollution bags harmed by miscellaneous bacteria should be treated differently. Those with mild pollution take the method of bagging and mouth-binding to control the spread, and then sterilize and inoculate. Take materials from seriously polluted broken bags, add 1% ~ 2% lime water and mix well, pile up and dry for 24 hours, and reuse next time. If the fruiting body is contaminated by green mold, it should be harvested in advance, and the ear base should be rubbed with limewater clarifier with pH 8 to control the spread.
