NOVELTY - Method for cultivating Agaricus bisporus, involves (a) preparing fermentation raw materials, (b) fermenting fermentation raw material, (c) transporting culture material to mushroom cultivation room, fixing frame on each mushroom bed, sowing culture material respectively, casing spawn, sterilizing and cultivating mushrooms, (d) obtaining cultivated mushroom and cleaning mushroom cultivation room, and (e) preparing organic fertilizer by processing and composting bagasse, and performing re-fermentation and maturation to obtain organic fertilizer.    USE - The method is useful for cultivating A.bisporus (claimed).    ADVANTAGE - The method is simple, reliable, convenient to perform and environmentally-friendly.    DETAILED DESCRIPTION - Method for cultivating Agaricus bisporus, involves (a) preparing fermentation raw materials by obtaining wheat straw, manure, gypsum powder, soybean meal and urea, where the selected wheat straw should be in bright yellow color without mildew, and has moisture content of 12-16%, the manure is dry manure has nitrogen content of 3-4%, 28% or less ash content, water content of 70-80%, and gypsum comprises amorphous calcium sulfate powder with purity of more than 98% and has particle size of more than 100 mesh sieve, soybean meal has moisture content of 10-15%, nitrogen content of 5.5% or more, and particle size of 30-50 mesh sieve, the urea has nitrogen content of greater than or equal to 46%, mixing 1.58-1.72% nitrogen, and 25% or less ash in a ratio of 30-33:1 to obtain mixed material, crushing wheat straw, spraying mixed material, mixing uniformly, spraying water on mixture, adding chicken manure, stirring uniformly, adding mixture into reactor, adding soybean meal, gypsum powder, and urea into reactor through hopper, adding water, and mixing uniformly to obtain mixed fermentation raw material, (b) fermenting fermentation raw material by controlling fermentation raw material moisture content to 75-78% before performing fermentation, stacking mixture to a height of 3-4 m, dding cellulose and hemicellulose and thermophilic microorganisms, mixing uniformly, performing primary fermentation at 70-80 degrees C for 3 days to form first rollover, again stacking mixture to a height of 3 m, performing second rollover for 3 days, again stacking mixture to a height of 2.5 m, performing third rollover for 3 days, collecting primary fermented material, allowing to pass through secondary fermentation tunnel, balancing mixture, heating, pasteurizing, cooling and culturing for 5-7 days, (c) transporting culture material to mushroom cultivation room, fixing frame on each mushroom bed, sowing culture material respectively, casing spawn, sterilizing and cultivating mushrooms, (d) obtaining cultivated mushroom and cleaning mushroom cultivation room, and (e) preparing organic fertilizer by processing and composting bagasse, and performing re-fermentation and maturation to obtain organic fertilizer.
