NOVELTY - Cultivating Agrocybe aegerita comprises e.g. (i) taking corn cobs, wood chip, tea seed cake, mushrooms tangs, calcium oxide, calcium carbonate, crushing, drying and pulverizing; (ii) adding mushroom tang particles, soaking, mixing leaching solution with mushroom slag sawdust, cotton seed hulls and bean cake, carrying out fermentation, turning once in a day, adding calcium oxide, light weight calcium carbonate, planting the fermented material, covering with soil, subjecting to fruiting management; and (iii) second and third mushroom harvesting, spraying mushroom tang leachate.    USE - The method is useful for cultivating Agrocybe aegerita (claimed).    ADVANTAGE - The cultivation process saves manpower and coal resources, and reduces environmental pollution.    DETAILED DESCRIPTION - Cultivating Agrocybe aegerita comprises (i) 42-48% corn cobs, 31-37% wood chip, 12-14% tea seed cake, 3-4% mushrooms tangs, 3-4% calcium oxide, 1% light weight calcium carbonate, crushing corn cob into the particle size of 3mm-5mm, diameter of the sawdust is 3-5mm hardwood sawdust, mushroom tangs are prepared by mushroom production process, drying and pulverizing into particles of 2-3mm; (ii) adding mushroom tang particles into the 20-30 times weight ratio of water, soaking at room temperature for 18-24 hours, then uniformly mixing leaching solution with mushroom slag sawdust, cotton seed hulls, and bean cake, piling the material into height of 1-1.2 m, width of 2-3 m, then controlling dry weight of material to 300-500 kg, placing in a pot for 4 weeks, again with diameter 10-15 cm of a stick and making vertical hole on upper stack, straight bottom, where hole density is 1/m3, and covering with grass thatch and carrying out fermentation, when the material temperature reaches to 60 degrees C for 24 hours, then turning once in a day, during first turning, adding calcium oxide, second time turning by adding light weight calcium carbonate, and turning for 3-4 times, continuing for 5-6 days, and stopping fermentation when the cultivation material moisture content reaches to 63-65%, cooling and planting the fermented material, covering with soil up to 1-2 cm thick, and subjecting to fruiting management; and (iii) carrying out second and third mushroom harvesting, depending on mycelial growth, spraying 4-8 kg of 0.01-0.02 g/ml mushroom tang leachate per square meter, the preparation of the leachate comprises adding mushroom tang granules into the 20 times weight ratio of water, soaking at room temperature for 18-24 hours, filtering to collect residue, and then made up to the original amount of by adding water with concentration of 0.05 g/ml, and adding water for dilution.
