First, the processing of mushroom house:
The mushroom house used for cultivation of Bailing Mushrooms generally uses vegetable protection facilities such as solar greenhouses and greenhouses. Before the mushroom cultivation, the film can be uncovered for two weeks. The material is then fumigated before entering the shed, and the house is usually painted Can be used as a Pleurotus ostreatus after the mushrooming place, but also before the feed with a chemical treatment once.
Second, the cultivation of materials and sterilization
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 fermentation material was mixed with 60%~65% of water and 2% of lime was added to make the pH value 8~8.5. 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. Fermentation time depends on the room temperature, when the temperature is high, the time can be shorter, and 7-8 days is appropriate. When the temperature is low, the number of days can be appropriately increased and the plastic film can 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%~60%, and the pH value to 8~8.5. The plastic bag is made of a 1733 cm-size folded polyethylene bag and holds 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.
When inoculated and cultured, the bacteria-killing bacteria bags are cooled to 30°C, they are transferred into the inoculation room for inoculation, and the inoculum size is suitable for covering the surface of the bacteria bags. 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 during the cultivation process. The air humidity should be below 65%, and the temperature should be kept at 25°C~28°C. After 45~60 days, the bag can be full and then it can be transferred to the mushrooming stage.
Third, mushrooming management
After the mycelium is full, let the mycelium grow for 1 week to make the hyphae go through. Then move the bag to a low temperature or reverse the operation to the mushroom shed. Grass curtain, and increase ventilation, low temperature stimulation, combined with water spray to promote mushroom bud formation. When the buds grow to the size of the thumb, open the bag to further increase the moisture. At this point, the air humidity should be maintained at 85% to 90%, and the temperature should be maintained at 8°C~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.
