How does tea tree mushroom miscellaneous bacteria pollution do? Is there any way to prevent and cure the pollution of miscellaneous bacteria of Pleurotus ostreatus: the contamination rate of Pleurotus ostreatus bags is higher than that of other mushrooms, the main reason is that the cultivation quantity is larger, and the general growers make no less than 5000 bags at a time, more than 10, 000 bags, heavy workload, mixing, bagging, sterilization, inoculation, sterilization and other links out of control. In particular, the pollution bags in the old mushroom area were not treated well, the spore index of space miscellaneous bacteria was increasing, and the stress resistance of miscellaneous bacteria was getting stronger and stronger. The common miscellaneous bacteria are mainly competitive miscellaneous bacteria such as Trichoderma viride, Alternaria alternata, Penicillium, Monascus flavus and so on. In particular, green Trichoderma is extremely harmful, once contaminated, causing the bacteria bag to be scrapped. Prevention and control methods of miscellaneous bacteria pollution of Pleurotus ostreatus: (1) cottonseed shell was fermented by adding water 24 hours in advance; (2) after adding wheat bran, the time limit of mixing and bagging to the upper stove was no more than 6 hours to prevent the matrix from becoming sour; (3) the sterilization temperature was controlled for 100 ℃ and lasted for 24 hours; (4) the transportation process prevented the material bag from breaking. 5. Inoculation should be carried out in sunny days and at night, and strict aseptic operation; 6. Attention should be paid to temperature control, moistureproof, ventilation and protection from light in germ culture. 7. Turn over the heap on schedule and deal with the contamination of miscellaneous bacteria in time. 8. When mite damage occurs, 73% carbamate EC can be sprayed 2000-3000 times.
