The polluted material of Pleurotus ostreatus can be replanted.

In the cultivation of Pleurotus ostreatus, the culture material is often scrapped by miscellaneous bacteria infection after inoculation because of serious environmental pollution, lax disinfection of mushroom room, careless operation process, aging of bacteria and so on. In order not to waste raw materials, the contaminated materials can be treated by the following two methods: 1. The pasteurization method uses 6000kg 7000g of lime and 400kg 500g of carbendazim for every 100 kg of contaminated material, and adjusts the contaminated material to 65% water content. After mixing well, pile the material as high as possible, use a 4cm thick stick to drill a hole vertically to the bottom of the pile, drill a hole every 30cm to 40cm, and rotate to pull it out. After beating, the fermentation was covered with film, and the pile was turned when the temperature of the material rose to 60-70 ℃. After resuming the heap, turn the heap twice according to the previous method, then cool down the heap in bulk, and connect the viable bacteria with a seed dosage of about 15%. two。 By atmospheric pressure sterilization, the contaminated materials were dried in the sun and raked with a rake for a total of 2 to 3 days. According to 100kg of contaminated material, 3000 grams of lime and 300g of carbendazim, the water content was adjusted to about 60%. After bagging, it was sterilized under atmospheric pressure for 10 hours, then stuffed for 12 hours, and then cold to room temperature. After inoculation, the temperature of the culture room was kept at 15-20 ℃, the mycelium could develop normally, the bag could be full in about 35 days, the mushroom bud appeared in 40 days, and the mushrooms could be harvested in 4-5 days. The development time is 5-7 days later than the normal material, 2-3 tide mushrooms can be harvested, and the biological efficiency is 70-80%.
