Pictures and videos on the method of planting mushrooms with cow dung

With the rapid development of cattle farming, manure pollution has become a big problem. According to relevant data, in some places, the pollution of cow dung to the environment has exceeded the total amount of industrial pollution, and some even reached more than twice. A cow produces more than 7 tons of manure per year, and a cow produces between 5 and 6 tons of manure per year. Due to the lack of attention to the treatment of cow dung in various places, there is basically no cow dung treatment facility in some places where cattle are concentrated. The method of planting mushroom with cow dung is sorted out by farming net. The following is listed for netizens 'reference. With cow dung mixed with rice straw fermentation as substrate to grow mushrooms, can be planted varieties of Agaricus bisporus, Coprinus comatus, mushroom and straw mushroom. 1. The formula of cow dung mushroom culture medium: A mushroom house needs 8000 kilograms of straw, 4000 kilograms of dried cow dung, straw needs to be dried without mold before use, cow dung needs to be crushed, and the diameter should not exceed one centimeter. The purity of cow dung should be above 80%. In addition to cow dung and straw, cake fertilizer and chemical fertilizer should be added to supplement nutrients and increase the porosity of the culture medium. Cake fertilizer needs 200 kg, calcium superphosphate 150 kg, compound fertilizer 100 kg, quicklime 200 kg. II. Method for treating straw of culture material: The straw is soaked in water and taken out, stacked into a 2-meter-high straw pile, placed for 5-7 days, and sprayed on the surface of the straw pile 1-2 times a day. 3. Preparation of mushroom culture medium of cow dung: 1. Mix the treated straw and cow dung together for fermentation, 2.2 meters wide, 30 cm high and 18 meters long. Each layer of straw is covered with a layer of cow dung, the proportion of cow dung is half, and then the straw is covered with a layer of straw and a layer of cow dung until all the straw is used up. 2. Watering in the process of building the pile, the principle is that the bottom layer is not watered, the middle layer is watered less, and the upper layer is watered more until there is water overflow around the pile. 3, such a good pile of material generally in the fourth day or so the temperature will rise to about 70 degrees, about 20-25 days, in this period of time to turn the pile four times, the first turn pile in the pile after 5-7 days, the appropriate moisture is to twist the straw with water overflow, the first turn pile after 5-6 days for the second turn pile, the second turn pile after 5 days for the third turn pile, at the same time fertilization, fertilization amount is: Cake fertilizer 12 kg, compound fertilizer 4 kg, calcium superphosphate 10 kg, the third turn pile about four days after the last turn pile, the last turn pile to adjust the PH value of the material between 7.8-8. 4. Secondary fermentation of culture medium: After the cultivation material enters the shed, it is fermented twice with high temperature steam at 58-60 DEG C for 24 hours, and then gradually reduced to 50 DEG C for 48-72 hours. V. Sowing method: The sowing time should be selected after 3 pm on a sunny day. Before sowing, water should be sprayed on the mushroom bed, and the seeds should be evenly sprinkled on the culture medium. The seed quantity is 1.5-2 bottles per square meter. VI. Management of mushroom growth period: The development stage takes about 25-30 days, and temperature control in development management is critical, with a maximum of 29 degrees and a range of 22-27 degrees. Seven days after sowing, hyphae covered the surface of the medium and began to spread to the lower layers. During this period, ventilation for 1 hour per day, ventilation for 1.5 hours per day after 7 days, 2-3 hours after 12 days, and ventilation for more than 10 hours after 20 days of sowing. After 20 days, the mycelium is full of culture material to be covered with soil. Soil covering should be carried out at temperatures below 28 degrees Celsius. 3-5 After days, turn over the soil again. Before covering the soil, the material must be exposed to strong sunlight for 2-3 days for disinfection. The thickness of the overburden is between 2.5 and 3 cm. VII. Management of mushroom fruiting period: After covering soil for 12 days, when soybean-sized mushroom buds appear in soil cracks, mushroom water should be sprayed once. The amount of water sprayed per square meter of mushroom bed is 2-3 kg. The mushroom water should be sprayed continuously for 2 days, and the temperature should be below 18 ℃. Spray nutrient water once during fruiting period to supplement nutrient deficiency. VIII. Harvest of mushrooms: Agaricus bisporus is generally about 5-7 days after budding, the cap is about to spread out, the spores have not been ejected, the diameter of the cap grows to 4-6 cm, and the mushroom stalk can be harvested when it is 3-5 cm long.
