How to breed mushrooms? How to prepare mushroom culture medium?

(1) The mushroom house is built in a higher place, with a wind tunnel at the top and skylights and floor-to-ceiling windows on the walls.

(2) The specification of mushroom bed is 1.2m wide, the bed bottom is 0.3m from the ground, the bed spacing is 0.4-0.6m, the interlayer spacing is about 0.6m, and there are walkways around.

2. Cultural materials.

(1) Raw materials: livestock manure, wheat straw, rice straw, gypsum powder and calcium superphosphate. The ratio of feces to grass is 7: 3 or 6: 4.

(2) Method: the straw is dried and cut off, the excrement is dried and crushed, soaked in clear water, stacked according to grass layers, and then covered on the mixed pile with a straw curtain; After 3-4 days, turn over the pile for the first time. If the water in the mixed pile is not enough, add a proper amount of water; After 7-8 days, turn over the pile for the second time, and add10.5 kg gypsum powder per 100 square meter of culture material; 1 1- 12 days later, the pile was turned over for the third time, and150g of calcium superphosphate was added to the culture medium of 100 m2; 13 on the same day, transfer the culture material to the mushroom room while it is hot, spread it evenly on the mushroom bed, seal the mushroom room, and raise the temperature in the mushroom room to about 60℃ for 2-3 hours; After 2-3 hours, the temperature is reduced to 52℃ for about 4-7 days.

3. sow.

(1) Sowing time: Sow when the temperature of culture medium is reduced to 28℃.

(2) Method: Sow seeds at a row spacing of 9cm×9cm, and sow 750ml of strains per square meter.

(3) Management: Pay attention to moisturizing after sowing, and strengthen indoor ventilation when hyphae begin to germinate and grow; When the mycelium has covered the surface and infiltrated into the culture medium, the mushroom bed is covered with a layer of fine mud, first with coarse soil (2.4cm thick, with water content of 20%) and then with fine soil (1.2cm thick).

4. Moisture.

(1) The bottom of the culture material and the covering layer should be wet, the top layer should be dry, the inside should be wet and the outside should be dry, and the temperature should be controlled at 10- 18℃.

(2) spraying mushroom water when small mushroom buds grow on the thick soil layer; When the fruiting body grows to the size of bean, spray more water.

(3) During the result period, the air humidity was kept at about 80-90%.

5. management.

(1) After harvesting autumn mushrooms for three times, topdressing them with 0.2% urea/ammonium sulfate, decomposed human excrement or 1% glucose.

(2) Spring mushrooms should be kept warm and moisturized from March, and topdressing should be done before the next batch of mushroom buds are formed.
