There are many varieties of oyster mushrooms, which are divided into four categories based on the temperature of their mushrooms: high temperature, wide temperature, medium temperature, and low temperature. In spring, the cultivated oyster mushrooms are generally wide-temperature type and high-temperature type, and the wide temperature type cultivars have a mushrooming temperature of 2 to 30Â°C and a high-temperature type of 10 to 32Â°C. In production, although the temperature is in line with the mushrooming requirements, the mushroom is generally less mature and its quality is not good in the late period. In fact, if we can strengthen the post-stage management of the spring planted oyster mushroom, we can still produce more mushrooms and produce as good as the previous period. mushroom. First, soaked in water. In spring, the ostreatus ostreatus bag was sterilized after 2-3 batches of mushrooms. The water in the bacterium bag was lost, and the fungus was shrinking. It was impossible to produce mushrooms or only a few small mushrooms. At this time, the water can be soaked. Dig a mud pit next to the mushroom farm, discharge the 3-4 layers of bacteria bags, cover it with a wooden board or bamboo plate, and then apply pressure to the water and pour the water into the pit. For 3 days, a small amount of compound fertilizer can also be added to the water to increase the nutrients in the bag. Supplemented with water and nutrients, Pleurotus ostreatus can continue to grow good mushrooms. Second, cover soil. Due to the late mushrooming, the temperature gradually increased, even higher than the high temperature limit of the oyster mushroom, so often can not mushroom or die mushroom phenomenon, then can be covered with soil treatment to reduce the temperature, ensure the temperature of the mushroom, soil temperature Generally lower than the temperature of 5-10 Â°C, Pleurotus ostreatus bags can be stripped of film, neatly discharged in a loach bed, which covers 5-8 cm of soil. Pay attention to 3 times of watering every day in the first 3 days of earth-covered soil. Third, prevention and treatment of pests. As the temperature rises and the hazards of disease increase, comprehensive prevention and control shall be carried out in time. 1. Clean up the environmental hygiene inside and outside the mushroom farm in a timely manner. 2, every other week, mushroom field with 800 times the enemy to spray once to reduce the source of insects. 3. In the mushroom field where there is no mushroom body, 800 dichlorvos and 500 times carbendazim solution are sprayed, but no medicine can be used when there are mushroom buds and mushroom bodies.
