Pleurotus ostreatus pollution material can be replanted

Pleurotus ostreatus cultivation, often due to serious environmental pollution, sterile mushroom house, sloppy operation, the aging of bacteria species caused by inoculation culture materials infected by bacteria scrapped. In order not to waste raw materials, the following two methods can be used to treat the contaminated materials: 1. Pasteurization uses 6000-7000 grams of lime per 100 kilograms of contaminated material, and 25% carbendazim of 400-500 grams will contaminate the material. Adjusted to a moisture content of 65%. After mixing well, as far as possible to pile up the material, with a 4 cm thick wooden rod in the pile vertically punched to the bottom, every 30 to 40 cm hit a hole, rotating pull out. After the film is over, the film is fermented and the temperature rises to 60-70°C when the material is expected to turn over. After the recombination, turn the stack twice according to the previous method, and then reduce the stack temperature, access to strong viable strains, with the amount of about 15%. 2. Atmospheric sterilization first dried the contaminated material, sun tweeted with tweezers, a total of 2 to 3 days drying. According to the contaminated material 100 kilograms, 3000 grams of lime, carbendazim 300 grams to the ingredients, the water content adjusted to about 60%, after bagging sterilization at normal pressure for 10 to 12 hours, and then bored for 12 hours, until the cold to room temperature After that, access to suitable age strains. After inoculation, the temperature of the culture room was maintained at 15-20°C, mycelium could develop normally, and the bags could be filled for about 35 days, and the buds could be seen in 40 days. The mushroom could be collected in 4 to 5 days. The development time is 5 to 7 days later than the normal material, and it can receive 2 to 3 tide mushrooms, and the biological efficiency reaches 70 to 80%.
