Tricholomalobayensc heim, belonging to the order Umbelliferae, mushroom material, white mushroom genus, is a kind of rare edible fungi in the development. Jinfu mushrooms in the domestic trade names are Lobayi mushrooms, Lobayi mushrooms, large mouth mushrooms, etc., in foreign countries, French mycologists heim, first found in Africa, and in 1970 named. In China Yunnan, Guizhou, Fujian, Guangdong, Hong Kong, Taiwan and other places have different degrees of natural distribution, often occurring around late spring to mid-autumn. The mushroom is rich in nutrients, according to the analysis of every 100 grams of dried products contain 27.56% protein, 9.58% crude fat, 38.44% total sugar, 8.20% crude fiber, its fruiting body fat, tender and white, taste slightly sweet, crisp and delicious, good storage, suitable for fresh sales and dry processing, y marketed by the green. Cultivation method adopts fermentation material bag type buried tube over soil cultivation, the specific technology is summarized as "five secrets": ① clever row production season: according to the optimum temperature of the differentiation and development of the seed entity of the golden mushroom is 20c~28℃, so the mushroom season is best arranged in the autumn August~September or the spring of March~May, when the natural air temperature is more suitable, and the biological conversion rate is also high. At this time, the natural temperature is more favorable and the biological transformation rate is high. According to the local climate data, localities should choose the stable temperature around 25℃ in spring and fall as the month of mushroom production, and take this as the boundary and count down 50~60 days as the best inoculation period. ②Scientific preparation of substrate: the following formulas are commonly used for culture medium, and you can choose any one of them. Formula one: straw 78% cottonseed hulls 18% lime 2% gypsum 1% calcium superphosphate 1% Formula two: corn cobs 50% cottonseed hulls 46% gypsum powder 1% lime 2% calcium superphosphate 1% Formula three: fungus chaff (dry waste) 60% straw 36% gypsum powder 1% lime 2% calcium superphosphate 1% Formula four: cottonseed hulls 96% gypsum powder 1% lime 2% calcium superphosphate 1% When preparing the culture material. Cut the straw into 3~5 cm length, put it in the pool with lime, soak it for 24~30 hours, then put it in the pool with pre-wetted cottonseed husk, add lime, calcium superphosphate and gypsum powder, and build a heap for fermentation. Pile fermentation time 10~15 days, the middle of the pile 2~3 times. The moisture content of the culture material is 60%~65%. Before ph sterilization 7~8. The treated culture material is put into 17x33cm or 22x40cm plastic bags, and then transferred to atmospheric pressure sterilization process. After the bag on the stove, the above temperature 100 ℃ to maintain 5 ~ 6 hours, after the cease-fire continue to smother 12 ~ 28 hours, unload the bag cooling. ③ temperature control inoculation of bacteria: when the bag material temperature drops to 25 ℃ or so when the bacteria. 17 cm bag using both ends of the seeding method, each bottle of strains can be inoculated 30 ~ 40 bags. Cultivation bags that have been inoculated with mycorrhizal strains, take wall stacking bags, stacking 4~5 layers, leaving a ventilation channel in the middle. When the germination of the strain, mycelium grows to 1/2 bag, the mouth of the bag will be loosened, so that oxygen penetration into the bag, after 30 ~ 40 days of cultivation, the mycelium grows full of bags, into the physiological maturity period. ④ timely mulching and moisturizing: the hair full of mycelium culture bag, timely moved to the field mushroom shed, take off the film, let it from the nutrient growth into the reproductive growth stage. At this time, the fungus tube should be discharged on the bed of the border to cover the soil. The height of the bed is 50~60cm, and the bottom of the bed is covered with a layer of woven bags, then 2cm of fine soil, and then the mushroom tubes are placed on the bed and covered with 3~4cm of humus. Lastly, spray water and cover the mulch with thatch or newspaper to keep moisture. Generally 8~12 days after mulching, white mycelium climbed on the soil surface. When the soil surface is covered with thick white mycelium, remove the bed thatch or newspaper to reduce humidity, so that the soil surface mycelium inverted. At this stage, the air humidity should be controlled at 85%~90%, and the temperature 20c~25℃ is suitable, meanwhile, strengthen the ventilation and increase the light, stimulate the differentiation of mycelium in the soil layer, and promote the twisting of the original base to form the substrate. ⑤ Strictly manage the mushroom production: from covering the soil to mushroom production, it usually takes 12~18 days. Strictly differentiate the different stages of growth and development of the mushroom during the mushrooming period. During the growth period of young mushroom, it grows in microclimate without spraying water, and it is better to spray water in the space on dry days; when the mushroom body grows to 3cm high, spray water 1~2 times a day, and the relative humidity of the air is 85%~90%; when the mushroom body enters into the maturity period, stop spraying water, so as to avoid rotting of the mushroom. During the whole mushrooming period, the temperature of the mushroom room should be around 25℃; pay special attention to ventilation and keep the air in the mushroom room fresh. It takes 12~15 days from the formation of protoplast to the maturity of the fruiting body of Agaricus blazei. The substrate is clustered or solitary. At the beginning, it is cylindrical, and at maturity, the stalk is thick and long, small at the top and large at the bottom, and the cap is spreading, with a smooth surface. When harvesting, hold the stipe in your hand and pull up the whole cluster. After harvesting, clean up the residues and aging mycelium on the bed surface, level the material surface, stop spraying water, continue spraying water after 5 days of resting and nourishing the mushrooms, spraying mushroom fungibond nutrient solution, controlling the temperature, ventilating, and lighting, and then the second wave of mushrooms will appear after two weeks. Generally, 4 tides of mushrooms can be harvested. With proper management, the bioconversion rate can reach 80%~100%. Source: Chengdu Seed Industry
