The soft rot of Pleurotus ostreatus is mainly characterized by the white mycelium of Pleurotus ostreatus growing spider-like on the surface of the trampoline and spreading rapidly, covering the bed surface and surrounding the fruit body. The fruiting body of the fruiting body is surrounded by the hyphae and is susceptible to disease. The pathogen spreads along its stipe, finally reappears as the fruit body stops growing, and the color is dark, rapidly softens, yellows, turns brown, and then rots.
One of the prevention methods is to strictly handle the mushroom shed. Before the mushroom shed was opened, the king of mushrooms was sprayed. After sealing for two days, the ground was sprinkled with lime powder at a dosage of 250 grams per square meter. The second is the spraying prevention during germination. Every 5 days or so spray 1 time Venus disinfectant 50 times, or bacteria kill 200 times and so on, pay attention to drugs do not spray directly on the mushroom bed or bacteria bag. The third is to strictly deal with earth-covered materials. In the case of cultivar wall or medlar cultivation, in particular when using surface soil, vegetable garden soil, and extracting soil from the old mushroom area, it is necessary to use drugs for sterilization and insecticidal treatment. Treatment method: first dry the soil, crushed, spray 60 times the mushroom scorpion disease and phoxim 600 times liquid, spray while mixing, mix and film after the heap stuffy, 7 days after the film can be unrolled, spread out , It can be used after smelling. Fourth, in the initial stage of disease, the cover soil shall be excavated with the culture material expanded by about 10 centimeters, and the bacteria must be sealed by spraying the bacteria. The spraying of water to the mushroom shed should be stopped, and the ventilation volume should be increased. If possible, the temperature of the shed should be reduced as much as possible. Also note that in the non-special case, the mushroom farmer should not be arbitrarily stringed.
