First, the construction of a high-risk mushroom house, ample water, sit north to south to build a house. The room width is 2.4 meters (two beds) or 4.5 meters (three beds), and the length is determined by the terrain. The specific construction method is the same as that of the ordinary oyster mushroom plastic shed. In order to improve the cultivation area, the retaining walls on both sides can be raised properly, and a simple bed frame can be erected with wooden sticks, covered with corn stalks, lotus root leaves, etc. It can be planted in 2-3 layers with a spacing of 60 cm.
Second, the cultivation of materials and fermentation
1. Prepare 1,500 kg of dry straw, 100 kg of dry cow dung, 15-20 kg of urea, 37.5 kg of superphosphate, 40 kg of raw gypsum powder, 45 kg of calcium carbonate, and 20 kg of quick lime.
2. The pile will be built in mid-to-late July. Before the pile is built, the wheat straw and cow dung shall be pre-wetted for 2 days before the construction of the pile. The humidity shall be: holding the cow dung in the hand, with 4-5 drops of water in the fingers; when the straw is distorted by hand, there will be water drops. The piles are north-south, piled 2.5 meters wide, 7.0-8.0 meters long, and 1.5 meters high, a total of 7 layers. On the first floor, first spread 30 cm thick straw on the ground, then sprinkle urea (1/7 of the total amount), then sprinkle 150 kg of cow dung. The thickness of the 2-7th layer of wheat straw is 20 cm, and the amount of cow dung is 2-6. Layers, each layer of 100 kg, the remaining all covered in the 7th layer, urea dosage per layer with the first layer. After the reactor is built, the temperature rises up to 75°C, and the stack temperature drops after 5-6 days.
3. After turning the stacks and building the piles for 7 days, 15 kg of lime were added to the first stack (the remainder was spread). The second gypsum powder was added, the pile width was reduced to 1.5-2.0 meters, the length was 7.0 meters, and the height was unchanged. The third addition of calcium phosphate, if the material temperature exceeds 60 °C, set a vent hole every 1.5 meters. The fourth addition of calcium carbonate (2/3 of the total amount). The 5th pH was adjusted to a pH of 7.2-8.0.
Three, sowing mushroom material into the room 1 week before, with 1.2% copper sulfate or 500 times carbendazim mushroom house fully disinfected. Then move into the house, shop 15-20 cm thick, until the material temperature drops below 28 °C, when the material does not have ammonia smell sowing. Use 1-1.5 bottles of bacteria per square meter, first spread the amount of 2/3 evenly on the surface of the material, shake the material surface by hand, so that bacteria species sink 3-5 cm, and then sprinkle the remaining bacteria in the material On the surface, gently beat with a wooden stick.
IV. Management after sowing
1. Within 3 days after sowing, the moisturizing main mycelia is suitable for growth of 20-25°C and relative humidity of 70%-75%.
2. Cover soil about 13-15 days after sowing (mycelium feed 2/3). The soil is suitable for loam or clay loam, with 3-3.5 cubic meters per 100 square meters. The coarse soil particle size is 1-1.5 centimeters, accounting for 2/3; the fine soil particle size is 0.3-0.5 centimeters, accounting for 1/3 of the mixed soil. The remaining calcium carbonate and 0.25 kg of dichlorvos were added to the soil. The water was sprayed well and mixed well. The moisture content of the soil particles was determined by rounding and pinching, and then covered with a film for 24 hours. When covering soil, the thickness of the surface soil is 3-3.5 cm and the requirements are the same.
3. Management after soil covering Adjust soil temperature in the first 3 days after covering the soil, so that the water content reaches 16% - 18%, that is, the coarse soil has no white heart, it has a round, flattened and no crack; the fine soil will split when pinched flat open. About half a month after covering the soil, part of the mycelium becomes thicker, and when the pea-sized fruit body is formed, the mushroom water is sprayed in a timely manner, generally 1-1.5 kg/m2 (according to the fungus material), divided into 2 days, sprayed 3-4 times a day. Then ventilate 1-1.5 hours. After 6 days, the fruit body grows to the size of soybeans and then sprays water once, which is generally 0.25-0.5 kg/m2. After 10 days, water was sprayed according to the amount of mushrooms, and more mushrooms were sprayed; less mushrooms were sprayed, and the air was sprayed for 30 minutes. After half a month of earth-covering, the fruiting bodies grew at a temperature of 13-18°C and a relative humidity of about 90%.
4. Management after harvesting and harvesting When the mushroom cover grows to 2-4 cm, it is harvested before the open umbrella. After the tidal mushroom is finished, the dead mushroom and the residual mushroom root on the mushroom material surface are promptly removed, and the hole is filled with the coarse and fine soil, and the water is re-sprayed for 1 time, and the mushroom is waited for.
5. Overwintering and spring management The mushroom sheds must be strengthened for overwintering to prevent snow from collapsing. The sphagnum bed was retrenched once, and a 1.0-centimeter fine soil was added. Before horror, check the moisture content of the material, sprinkle 50 grams of ash per square meter, spray wet. Spray 1000 times of dichlorvos within 3 days of convulsions and hang a piece of dichlorvos on the ventilated area to prevent insects. The management after the temperature rises is the same as the management of the fall landfill. Harvested until the end of June.
Cultivation of agaricus spp
The mushroom is also known as mushroom, white mushroom, and mushroom. It is nutritious, delicious, and internationally popular. If the cultivation of Agaricus bisporus with wheat straw and cattle and horse dung is used as a raw material, the investment is small, the benefit is high, and there is promotion value.
