The use of cow dung and straw for the cultivation of the organic mushroom Pleurotus eryngii has not only less investment and considerable benefits, but also purifies the environment, turns waste into treasure, and controls the environmental pollution of cow dung and other wastes that currently exist in rural areas. Its organic cultivation techniques are as follows: One, ingredients 100 m2 of stockpiling requires 1500 kg of wheat straw, 1250 kg of cow dung, 40 kg of phosphate fertilizer, 40 kg of gypsum, and 50 kg of lime with a pH of 7.5-8. 1, wheat straw pre-wet according to the formula to take wheat straw, soaked in batches of water, when the wheat straw evenly absorbed, layered stacked side of the material yard. 2, wheat straw treatment of wheat straw pre-wet on the third day, a layer of lime powder on the wheat straw, spray 1 water, then sprinkle urea, then spread a layer of wheat straw, and so on. After pre-stacking, 25 kg of urea, 7.5 kg of lime powder and about 23 cubic meters of stockpiles were used. 3. Prepare the heap before preparation. Before building the heap, pulverize the cow dung and cake fat and mix it evenly. Then use 1% lime water to pre-wet it until it can be held in a hand. When it falls into the ground, disperse chemical fertilizer, gypsum and lime. Evenly spread on cow dung and mix well. Cover it with plastic sheet and wait. 4. Build a pile of pre-stacked wheat straw on the stockyard, 30 centimeters thick, 1.8-2.2 meters wide and 8-10 meters long. Then sprinkle a layer of cow dung mixture on the surface of the material, and so on. Until the end of the pile, the manure was finally covered with manure mixture on the surface of the material and covered with a layer of grasshoppers. Spray 1-2 times of water on the grass every day. Turn the heap on the 7th day after the pile is piled up. Make proper water supply and no water can flow from the edge. In another five days, a second turn is performed, and lime water is made with 15 kg of lime powder for replenishment. The 3rd turn was carried out 5 days after the second turn. Simultaneously, the pH was measured. The pH was adjusted to 7.5-8 with lime water, the water content was kept at 65%, and then stopped for two days. 5, the culture material on the cultivation of the bed frame with a film cover Yan, heating, when the material temperature rose to 58 °C -60 °C when maintaining 8-12 hours, then dropped to 48 °C -52 °C for 13 days, waiting It can be sown when the temperature drops to 28°C. The well-fermented culture material has a tan color, soft and elasticity, moisture content of about 64%, pH value of 7.5-8, hand odor, sourness, and ammonia odor. Second, sowing The containers, inoculation kits, and hands of operators must be sterilized. First spread the 1/2 of the amount of bacteria evenly on the surface of the material, and then use the middle finger to insert a slight vibration to the material so that the bacteria can fall uniformly into the material at 3-5 cm, and then evenly spread the remaining bacteria in the material. Face. Use 1-1.5 bottles per square meter. Third, culture bacteria cover soil 1, after sowing management sowing after the shed to maintain the temperature of 22 °C -25 °C, the maximum does not exceed 28 °C, humidity of about 75%, 7 days after sowing, hyphae normal growth, after about 20 days of mycelium covered the bottom. 2. Formula for earth-covering materials: 100 square meters requires 3100-3250 kg of loam, 17.5 kg of phosphate fertilizer, 20 kg of calcium carbonate, 100-150 kg of fermented wheat bran, 2/3 coarse soil, and 1/3 fine soil. In the first 3 days, add 5% formaldehyde 10 kg per cubic meter, stirring while spraying, then add a film, boring for 24 hours, and then use lime to adjust the humidity and spray dichlorvos. Four, mushrooming Management of mushroom shed temperature 14 °C -16 °C, air humidity 85% -90%. Spray to do ground spray, less spray, when the mushroom cover diameter to 2-4 cm, the edge of the volume, the membrane is not broken When harvesting, each batch of fluid must be rehydrated once. Nutritional liquid formula 1 potato boiled liquid plus edible nutrients. 2 mushroom handle precooking liquid plus edible nutrients.
