The use of straw and manure as the main raw material for cultivation of mushrooms in winter free field can greatly increase the income, and the residue after cultivation can also be returned directly to the field or as a raw material for bio-organic fertilizer. Now we will use the technique of cultivation of mushrooms in winter free fields as follows: When formulating material stocks for cultivation, the per-m2 mushroom bed was counted, and 12.5-13.5 kg of dry straw, 0.8 kg of rapeseed cake, 0.45 kg of gypsum powder, 0.45 kg of superphosphate, 0.45 kg of compound fertilizer, and 0.45 kg of lime powder were used. The required raw material per acre can be converted into 390-400 square meters per mu of single-layer cultivation area. The process of building a pile of raw materials into the stockyard dry straw soaked in pre-wet 12-18 hours to build a stack of straw material (heap width of 2.5 meters, top height of 1.5-1.6 meters, four sides high 1.2-1.3 meters) built vertically pile by layer. Lime is added at the first turnover, and auxiliary materials such as rapeseed cake are added layer by layer when the pile is built. Water was transferred from the beginning of the third floor and poured into the heap layer by layer. After stacking, the pile was piled every 5 days and humidity of the stack was controlled. The standard of high-quality cultured materials was as follows: rice and herbs were in harmony, yellow-brown or tan, toughness was not strong, no serious ammonia smell and other erosive taste, water content was 60%-65%. Twisting scaffolding is usually cultivated in a shed style and single-layer cultivation bed. The shed is 1.7-1.8 meters high, 4 meters wide and 10-15 meters long. First, in the center of the shed, a 1.6-meter-wide cultivation bed was made. On both sides of the center-cultivation bed, the width of the operation was 40 cm wide and the depth was 25 cm. Thereafter, 60 cm wide cultivation beds were made on the other side of the roads. Leave 20 cm of space on each side of the shed. The shed covering method can adopt the "sandwich" type, that is, grasshopper in the middle and the outer and inner layers are all films. The material of the shop should be even and thick, with a thickness of 20-25 cm. The moisture content of the culture should be maintained at 60%-65%. Seeding when the feed temperature drops to about 28°C. When sowing, the strains will be scooped out from the bottle and scattered, and evenly sowed in the material surface or material gap. Afterwards, clean the material surface with a clean board to facilitate the contact between the strain and the culture material. After germination management, 1-3 days after sowing, the main moisturizing and ventilation, temperature control below 28 °C, in order to promote the germination of the mycelium as soon as possible; 3-7 days after sowing, the basic germination of mycelium and start eating, the joint less ventilation Ventilation; After 7-11 days of sowing, the hyphae begin to eat horizontally, and the ventilation volume should be gradually increased to increase the thick growth of the mycelia; after 10-15 days of sowing, the mycelium in the material layer grows more than 1/2 in depth. . In the year of covering the soil, the field where mushrooms were cultivated was not applied, and the soil below the tillage layer was broken into pieces with a diameter of 1-1.5 cm. Usually, it is selected to be wet, not sticky, dry, loose, fluffy and breathable, strong in water retention, and has a certain fertility. Loam or sandy loam with a pH of about 7.2 is used as a cover soil. Before applying soil, use pesticides to remove the bacteria and pests from the soil. The material surface is sprayed once with a 1:1 equivalent amount of Bordeaux mixture 500-800 times.
