The Production and Cultivation Techniques of Bailing Mushroom
First, the cultivation of raw materials and mushroom house treatment Pleurotus ostreatus mushroom house generally used to protect the facilities of greenhouses, such as greenhouses, greenhouses, etc., before the best mushroom can uncover the film drying two weeks before the material into the shed and then use the agent Fumigation 1 times, the general house needs to be painted before it can be used as a Pleurotus eryngii mushrooming place, but before the feeding, it should be treated with the agent once. Second, the preparation and sterilization of cultivation materials 1. Preparation 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 and fermentation is preferably about 300 kg, with a stack height of 1.2 to 1.4 meters and a width of 1.1 to 1.5 meters, and the length is not limited. The heap is too small to heat up and the fermentation is impervious; the heap is too large to be in the middle of oxygen and it is not convenient to turn it around. 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 adjust the water content to 55% to 60%, and adjust the pH to 8 to 8.5. The plastic bag is made of 17cm 33cm size folded polyethylene bags, and it contains 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. Note that the sterilization should be thorough. Third, the inoculum culture and other fungi-killing bacteria bag cooling to 30 °C, into the inoculation room inoculation, inoculum size to cover the surface of the bag is appropriate. During the course of inoculation, pay attention to the disinfection of personnel and utensils, do not cause artificial bacterial contamination, and incubate the bacterial bags in the room after inoculation. 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. Care should be taken to avoid light in the cultivation process. The air humidity should be below 65%, and the temperature should be kept at 25°C to 28°C. After 45 to 60 days, the 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, open the bag to further increase the moisture. At this time, the air humidity should be maintained at 85% to 90%, and the temperature should be maintained as much as 8°C to 15°C. When the Pleurotus eryngii grows to the size of a 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. When there is a lack of ventilation, malformation mushrooms or tall mushrooms are prone to appear. At the same time, care should be taken not to blow the wind directly on the Pleurotus citrinopileatus to prevent the mushroom from cracking due to excessive water loss. 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. Pleurotus ostreatus should be promptly cleaned after harvest to prevent contamination. Bailing mushroom body white, thick meat, low water content, is conducive to transport. After harvesting, fresh packaging or processing shall be timely packaged.
