NOVELTY - Cultivating Pleurotus citrinopileatus mushroom comprises e.g. taking sawdust, soybean cake, P. citrinopileatu mushroom stalk, lime, and gypsum, drying P. citrinopileatu mushroom production waste and smashing into particle, adding clean water in mushroom stalk particle, soaking, mixing leaching solution with dried P. citrinopileatu mushroom stem residue and wooden meal, adding bean cake mixture, stacking material, controlling dry weight, covering tarpaulin for natural fermentation, adding lime during first time turning, and adding gypsum during second time.    USE - The method is useful for cultivating Pleurotus citrinopileatus mushroom (claimed).    ADVANTAGE - The method promotes beneficial microorganism breeding, improves the microorganism flora in material, accelerates cultivation material after fermentation with high active bacterium and active metabolite product, promotes Pleurotus citrinopileatus mushroom growth, can obviously increase yield, overcomes the long-term use of pesticide, bactericide and chemical synthesis series fertilizer, avoids reducing of Pleurotus citrinopileatus mushroom quality, improves the quality of Pleurotus citrinopileatus mushroom, saves labor, reduces the environmental pollution, thus it is environmentally friendly.    DETAILED DESCRIPTION - Cultivating Pleurotus citrinopileatus mushroom comprises mixing materials, fermenting, paving bed, seeding, spawning, coloring and fruiting management, specifically comprising (i) mixing material: taking 48-54% corn cob, 25-31% wooden meal, 11-13% soybean cake, 3-4% mushroom stalk, 3-4% lime, 1% gypsum and 1% calcium superphosphate, crushing corn cob into 3-5 mm particles, wooden meal is obtained after crushing broadleaf wooden meal to a particle diameter of 3-5 mm, based on dry matter, where the shiitake stem is waste material produced by mushrooms, drying, and crushing into 2-3 mm granules, (ii) adding 20-30 times the weight ratio of clean water in Pleurotus citrinopileatus mushroom stalk particle, soaking for 18-24 hours at room temperature, mixing leaching solution with dried Pleurotus citrinopileatus mushroom stem residue and sawdust uniformly, adding soybean cake mixture, piling material to height of 1-1.2 m, and width of 2-3 m, trapezoidal stacking to any length, controlling the dry weight of each stack of culture material at 300-500 kg, after stacking, tapping for four weeks, inserting number of vertical holes by wooden stick with diameter of 10-15 cm in the stack, at stack bottom, the air density is 1/m3, finally covering tarpaulin to make up the natural fermentation, after material temperature reaches 60 degrees C, maintaining for 24 hours, then turning once a day, adding lime during first time turning, adding gypsum and calcium superphosphate during second time turning, turning 3-4 times, lasting for 5-6 days, ending fermentation, maintaining moisture at 63-65%, heat dissipating fermented material, directly paving in furrow bed for seeding, when mycelium grow, entering color changing and fruiting management process, and (iii) fruiting management process: harvesting Pleurotus citrinopileatus mushroom, full spraying 0.01-0.02 g/ml Pleurotus citrinopileatus mushroom leaching solution, spraying 5-7 kg per square meter, where the preparation of leaching solution comprises adding 20 times of clean water in Pleurotus citrinopileatus mushroom particles, soaking for 18-24 hours under normal temperature, removing filter slag, supplementing water, obtaining leaching solution with concentration of 0.05 g/ml, and adding clean water to dilute.
