Bailing mushroom cultivation technology
First, the cultivation of raw materials and mushroom house processing mushroom room generally use vegetable protection facilities, such as greenhouses, greenhouses, etc., before the mushroom can be best film uncovered for two weeks, the material before entering the shed and then fumigated with a chemical agent, generally After the house needs to be painted, it can be used as a mushrooming place for Pleurotus ostreatus, and it should be treated with chemicals once before feeding. Second, the cultivation of materials and sterilization 1. Cultivation of cultivation materials: cottonseed husk 100 kg, corn flour 5 kg, bran 5 kg, lime 3 kg, plaster 2 kg. 2. Converting Fermentation: The material for composting fermentation is preferably about 300 kilograms, with a stack height of 1.2 to 1.4 meters and a width of 1.1 to 1.5 meters, with an unlimited length. The fermented material is mixed with 60% to 65% of water, and 2% of lime is added to make the pH value 8 to 8.5. After the pile was built, it was punched and ventilated. The hole spacing was 30 cm. The top of the stack hit 1 row, and the side hit 2 to 3 rows. The fermentation time depends on the room temperature. When the temperature is high, the time may be shorter, and it is appropriate to use 7 to 8 days. When the temperature is low, the number of days may be appropriately increased and the plastic film may be covered. During the fermentation process, care should be taken to turn over and turn over every other day. The fermented material should be tan-colored and free from acid odor. 3. Bagging sterilization: The fermented material needs to re-measure the moisture, and the water content is adjusted to 55% to 60%, and the pH is adjusted to 8 to 8.5. The plastic bag is made of a 1733 cm-size folded polyethylene bag with 0.75 to 1 kg of wet material. When hand-loading, hand-pressing tightly while mounting, the compactness can be grasped according to the power of the machine. The loaded material is sterilized under high pressure for 2 to 3 hours, or sterilized under normal pressure for 14 to 16 hours, and the sterilization must be thorough. Third, the inoculum culture and other fungi-killing bacteria bag cooling to 30 degrees Celsius, the inoculation into the inoculation room, inoculum size to cover the surface of the bag is appropriate. During the inoculation process, care should be taken not to cause artificial bacterial contamination. After the inoculation, the bacterial bags should be cultured indoors. In the first 3 days after inoculation, the bag was not to be sterilized. After 1 week, it was checked for any bacteria contamination, and the bacteria were cleaned out and allowed to be reused after air sterilization. During the cultivation process, care should be taken to avoid light. The air humidity should be below 65%, and the temperature should be kept at 25-28 degrees Celsius. After 45-60 days, the bacterial bag can be full, and then it can be transferred to the mushrooming stage. Fourth, mushroom management until the mycelium full, then let the mycelium for 1 week of anti-filament growth, so that the mycelium hair through, and then move the bag to a low temperature or reverse the operation of the mushroom shed, during the day cover Grass curtains will be used to remove the grass curtains in the evening and increase ventilation to stimulate them at low temperatures. The combination of water sprays will promote the formation of mushroom buds. When the buds grow to the size of the thumb, the bag is opened. At this time, the air humidity should be kept at 85% to 90%, and the temperature should be kept at 8-15 degrees Celsius. When the mushroom grows to the size of the table tennis ball, it is put out of the bag mouth and the ventilation volume is increased to ensure that the mushroom shape is normal. V. Timely harvesting and cleaning When the Pleurotus ostreatus is mature to eight, it must be harvested in time to prevent the spores from falling and affect the yield and quality. Generally, one mushroom can be produced per bag, and the weight of each mushroom is 150-250 grams. Only one mushroom is produced, but after further management, two tidal mushrooms can be produced. After harvesting, it should be promptly cleaned to prevent pollution.
