Analysis of cultivation benefit of Agaricus bisporus: Agaricus bisporus is a kind of food with rich nutrition and therapeutic value. It has a bright white appearance and crisp and tender meat. It contains more than 65438 kinds of amino acids, vitamins and minerals needed by human body, which can enhance human body's disease resistance and prevent liver cirrhosis and arteriosclerosis, and is deeply loved by consumers.
In addition, the market price of Agaricus bisporus is not high, and it is a variety of mass consumption. It can be sold to hotels and restaurants, and it can also enter the public table in large quantities. Large market capacity and good market prospects. Farmers grow in greenhouses. A greenhouse covers an area of 1.3 mu and can cultivate 1, 000 square feet of white mushrooms. Bamboo, iron wire, nails and other materials. Building a greenhouse: 15000 ~ 000 yuan; Plastic film: 500 yuan straw and straw curtain (for building greenhouses and making nutrients): 4,000 yuan; Strain: 1 100 bags, each bag of 2 yuan, with a total investment of 22,200 yuan.

profit
Generally, the greenhouse can be used for about 7 years. Except for straw curtains, straws and plastic films, they need to be replaced every year, and there is no need for maintenance in the second to third years. After 3 years, iron wires, nails and bamboo can be replaced at any time if they are damaged.
The first income is: 6300 ~ 1 1300 yuan.
The income in the second year and beyond is: 24,200 ~ 28,300 yuan.
The planting management method of Agaricus bisporus is as follows: first, lay a layer of fresh wheat straw with a thickness of 3 cm on the mushroom bed in the shed, and then spread the fermented culture material evenly on the mushroom bed, and the appropriate thickness of the material layer is 15-20 cm. Then fumigate and disinfect with 10g potassium permanganate and 20ml formaldehyde per cubic meter of space. After 24 hours, it is difficult to open the doors and windows for ventilation. When the material temperature drops to 28? Sowing can be carried out when the temperature is below C, and a bottle of 500 ml bottled strain is used per square meter. Spread the strain evenly on the surface of the material, and gently compact it to make the strain sink into the material about 2 cm.
Close the doors and windows properly within 3 days after sowing, keep the air humidity about 80%, and promote the germination of strains. Be careful that the temperature in the shed does not exceed 30? C. Otherwise, properly ventilate and cool down at night. About 15 days after sowing, the mycelium is covered with soil when it is basically full of material layer. Covering method: it is best to choose soil with good water absorption, granular structure, many pores, wet and non-sticky and dry. Every 100 square meter of mushroom bed needs about 2.5 cubic meters of soil. Mix 1.5%-2% lime powder first, then use 5% formaldehyde aqueous solution to soak the soil, and cover it when it is not sticky by hand, and the covering thickness is 2.5-3.5 cm when it is caked and scattered.
After covering the soil, adjust the water content to keep the water content of the soil layer at about 20%. The humidity of the covered space should be kept at 80%-90%, and the temperature should be 13-20? C (the optimum temperature is 15- 18? C) Testing. Spraying water according to the wet and dry conditions of the soil layer and strictly controlling the temperature and humidity are the keys to high quality and high yield of Agaricus bisporus.
Diseases and pests lurk in the culture medium, which do harm to the mycelium of Agaricus bisporus after sowing, resulting in difficulty or no fruiting.
Solution: thoroughly clean the mushroom shed and surrounding environment; Use? All diseases are stupid? Treating and covering the soil, and spraying it once every 3-7 days during the spawning and fruiting stages; Sprinkle lime powder on the vents and air inlets of the mushroom shed to prevent pests from crawling in.
