Agaricus bisporus cultivation method

According to the experience of cultivation of Agaricus bisporus for many years, we have boldly reformed the cultivation techniques and the yield has been significantly improved compared to the original. Now we introduce the cultivation techniques as follows. First, Agaricus is a moderately low temperature type. The suitable temperature of the mycelium is 6°C to 32°C, and the optimum temperature is 20°C to 28°C. The suitable temperature of the fruit body is 8°C to 22°C, and the optimum temperature is 14°C to 18°C. The best sowing date should be from September 5th to 15th. Based on this estimate, the fermentation time of the culture material should be between August 10 and 20th. Second, the formulation of culture materials (calculated on 100 square meters): 1500 kg of wheat straw, 1,000 kg of dried cow dung, 30 kg of urea, 32.5 kg of superphosphate, 30 kg of gypsum powder, 20 kg of calcium carbonate, and 15 kg of lime. Third, culture material fermentation: 1. Place selection: should choose ample water, convenient drainage, close to the mushroom shed. 2. Build a pile: The wheat straw is pre-wet for 2 days before the construction of the heap, and the moisture is adjusted to 70%-73%. First put the pre-wetted wheat straw on the ground, with a thickness of 0.3 meters, a width of 1.5 meters, a length of 9 meters, sprinkled with 1/7 urea and 1/7 cow dung. After being completed layer by layer, the height of the pile is 1.5 meters and the number of layers is seven layers. 3. Turning over the pile: The first turning of the pile: After the construction of the pile, the dumping began 7 days later, plus compound fertilizer and superphosphate. The moisture content of the wheat straw is 68% to 70%. When the dumplings are over, sprinkle with lime powder. In the second turn of the stack, gypsum powder was added 6 days after the first turn, but the width was expanded to 2 meters, the height was unchanged, and the length was convenient. Cover the film in a timely manner in case of rain and open it immediately after the rain stops. The third turnover was carried out for 3 days after the second turnover. The pH was adjusted to 7.2 to 7.8 during turning and the moisture content of the culture was 63% to 65%. Fourth, the whole material inoculation: The fermented culture materials will be moved into the greenhouse, covered with plastic film and straw curtain, waiting for the material temperature dropped to 28 °C when starting the whole material. The culture material was made into a turtleback shape on a trampoline. After spreading a bottle of 1 bottle per square meter, spread it evenly, gently tap it with a wooden board and cover the newspaper for 3 days. After germination, the newspaper was opened. Ventilation begins gradually every day and the temperature must be controlled below 27°C. V. Cover soil: From inoculation to cover soil, generally about 10 days to 15 days, 3 cubic meters of fertile soil per 100 square meters is required. First, the soil should be sieved once with a 2 cm sieve, add 15 kg of lime and mix well, adjust the moisture content between 16% and 18%, then cover the soil 2.5 cm to 3 cm. After covering the soil, ventilate every day and increase the ventilation time after 7 days. The temperature of the mushroom shed is required to be below 23°C and the relative humidity is between 80% and 85%. 6. Mushroom management: 13 days to 15 days after covering the soil, the mycelium climbs onto the soil surface at 2/3, and sprays 1.5 kilograms of water per square meter. It is sprayed in two days. Each time the water is sprayed, it must be ventilated. Hours or more. 5 days to 7 days to start the first mushroom, when the relative humidity of the mushroom bed should be maintained at 90% to 95%, when the fruiting body grows to a large bean size, spray 500 grams of quality water per square meter to spray Less spray. After the first batch of mushrooms were harvested, the water was stopped for 3 days to 5 days. After the hyphae were recovered and healthy, the second batch of mushrooms was able to be unearthed as scheduled. Generally, the harvest was completed in May of the following year. ~ 8 mushroom.
