NOVELTY - Cultivating Pholiota nameko plant, comprises (i) taking corn cob, soybean, mushroom stalk, lime and gypsum, and crushing corncob, and pulverizing; (ii) mixing mushroom slag leachate with corn cob, and mixing with soybean cake, and stacking; and (iii) carrying out fruiting management by harvesting mushroom twice, and completely spray mushroom slag leachate onto mushroom bed, and preparing leachate by adding water into mushrooms slag particles, soaking, filtering the residues, adding water to make up the volume, and adding 0.05 g/ml mushroom slag leachate, and diluting by adding water.    USE - The method is useful for cultivating Pholiota nameko plant (claimed).    ADVANTAGE - The method promotes growth of beneficial microbes rapidly; improves the utilization rate of microbial flora feedstock; increases the catalytic decomposition of cultivation material; produces fermentation cultivation material having high activity of beneficial bacteria and its active metabolites; facilitates good growth effect of mushroom due to slippery texture, and biological conversion rate of moisture-proof mushroom; saves labor intensity, coal and other resources; and emits low-carbon content materials, and thus it is environmental friendly.    DETAILED DESCRIPTION - Cultivating Pholiota nameko plant, comprises (i) taking 72-78% corn cob, 14-18% soybean, 3-4% mushroom stalk, 4-5% lime and 1% gypsum, accounting to dry matter of the raw material, and then crushing corncob into particle size of 3-5 mm, and taking mushrooms stalk and wastes, drying, and pulverizing into particles of 2-3 mm; (ii) adding water in an amount of 20-30 times the weight of mushrooms stalk and wastes at room temperature, soaking for 18-24 hours, and uniformly mixing mushroom slag leachate with corn cob, and mixing with soybean cake, stacking the material to a height of 1-1.2 m, width of 2-3 m, and length of up to not limit to ladder-shaped stack, controlling the dry weight of each stack in culture medium at 300-500 kg, and tapping for 4 weeks, and inserting a wooden stick straight into the bottom of stack to a diameter of 10-15 cm under aeration condition, where the stomatal density is 1 month/m3, and finally covering the stack with grass thatch for carrying out natural fermentation, maintaining for 24 hours once the material temperature reaches 60 degrees C, and then turning once a day, adding lime while turning for first time, and adding gypsum while the turning for second time, turning totally for 3-4 times for 5-6 days, terminating the fermentation process, obtaining cultivation material having a moisture content of 63-65%, and fermenting by adding cultivation material, cooling, directly adding into a furrow bed for sowing spawn, obtaining mycelium completely covering the material until the color changes; and (iii) carrying out fruiting management by harvesting mushroom twice, and completely spray 0.01-0.02 g/ml mushroom slag leachate onto mushroom bed, spraying 4-6 kg/m2 mushroom bed, and preparing leachate by adding water in an amount of 20 times into mushrooms slag particles, soaking at room temperature for 18-24 hours, filtering the residues, adding water to make up the volume, and adding 0.05 g/ml mushroom slag leachate, and diluting by adding water.
