Raw material treatment: dig a 1 pit near the mushroom shed, with a length of 6 meters, a width of 2.5 meters and a depth of about 0.8 meters (the size of the pit can be flexibly controlled according to the amount of raw materials). Cultivate the excavated soil around the pit, so that the depth of the pit increases to 1 .5m. 1 layer of plastic film is laid in the pit, and then1layer of forage is laid, and so on until it is filled. The top layer is lime powder, and the total amount of lime is about 8% of the total forage. Pressurize and precipitate on forage to prevent forage from floating. Finally, fill the pit with water until there is no forage. At the same time, the bran, which accounts for 8% ~ 10% of the total wheat straw, is put into a bag and soaked for 24 ~ 36 hours.
Entering the shed, building ponds and sowing: pick out the soaked forage, drain it for half an hour and enter the shed. The boundary is north-south, with a width of 0.9 ~ 1 .0m. First, lay 1 layer of grass with a thickness of about 20 cm, and then sprinkle1layer of treated bran. Leveling by hand, slightly compacting, and sowing 1 layer. Take out 1/3 plants according to the sowing amount of 0.75 kg per square meter, break them into pieces the size of thumb belly, and then sow two rows of plants on both sides of wow according to the specifications of hole spacing and row spacing of about 10 cm. The middle part; Because the temperature of the material will be too high and burn out the strains, it will not be broadcast. After that, 1 layer of forage grass and bran with a thickness of about 15 cm was paved, and the remaining 3/2 plants were all planted on the whole bed surface. Finally, sprinkle 1 layer of forage thinly on the bed surface to protect the strains. After proper compaction with wooden boards, the ridge will be made into arc covering soil. The total thickness of the material is 30 ~ 35 cm, and the width of the aisle is 30 cm.
Covering with soil and film: after the foundation bed is pressed into an arc shape, cover the surface of the material with 1 layer of 2-4 cm thick cohesive soil. Some decomposed fermented manure can be mixed in the aisle. After covering the soil, cover the bed with 1 layer of agricultural film to keep warm and moist. Waste pieces should be disinfected with lime water or potassium permanganate before use. After mulching with plastic film, insert 1 thermometer into the material, and observe the temperature every day to control it within a suitable range. The temperature of the material should not exceed 40℃. If it exceeds 40℃, the film should be uncovered immediately for ventilation, and holes should be made in the bed with wooden sticks to dissipate heat. After covering the shoots with plastic film for 3 days, uncover the film several times a day and ventilate for 10-30 minutes each time. On the 7th-8th day, bacteria can spread all over the bed surface. For this item, the arch should be supported on the bed and covered with film. Open both ends of the arched shed and let it ventilate half. Don't cover the sides too tightly. If the temperature and humidity are suitable, the arch shed can not be used.
Germination accelerating management: Germination accelerating starts about 10 day after sowing, and attention should be paid to uncovering the film and ventilation. When the mushrooms grow for a long time, fill the aisle with water to keep them moist and cool down. If the temperature and humidity are suitable, the film should be uncovered and ventilated to prevent the mushroom buds from dying due to high temperature. If the bed is too dry, you can dig 1 pit beside the shed, cover it with film, put it in cold water, preheat it and spray it on the bed surface. 2 ~ 2 days after germination, 4 ~ 5 days per tide, 2 ~ 3 times a day. The second tidal mushroom is produced every 3 ~ 5 days, and it can generally be picked 1 ~ 4 times, and the whole mushroom picking period is 20 ~ 25 days.
