NOVELTY - Hericium erinaceum cultivation method comprises e.g.(i) taking sawdust, cotton seed hulls, bean cake, mushroom tang, calcium phosphate monobasic, monopotassium phosphate; (ii) adding mushroom tang particles, soaking, mixing leaching solution with mushroom slag sawdust and bean cake, carrying out fermentation; (iii) turning once in a day, adding gypsum, calcium superphosphate, monopotassium phosphate and turning; (iv) cooling, planting the fermented material, subjecting to fruiting management; and (v) carrying out harvesting, depending on mycelial growth, spraying mushroom tang leachate.    USE - The method is useful for cultivation of hericium erinaceum (claimed).    ADVANTAGE - The method saves manpower and coal resources, and reduces environmental pollution.    DETAILED DESCRIPTION - Hericium erinaceum cultivation method comprises (i) taking 57-63% sawdust, 16-22% cotton seed hulls, 15-17% bean cake, 3-4% mushroom tang, 0.4% calcium phosphate monobasic, 0.1% monopotassium phosphate, 1% gypsum, the particle size of the sawdust is 3-5mm hardwood sawdust, the mushroom tang is produced using mushrooms 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; (iii) when the material temperature reaches to 60 degrees C for 24 hours, then turning once in a day, during first turning, adding gypsum, second time turning by adding calcium superphosphate, monopotassium phosphate, and turning for 3-4 times, continuing for 5-6 days, and stopping fermentation when the cultivation material moisture content reaches to 63-65%; (iv) cooling and planting the fermented material, covering with material up to 1/2, covering with soil up to 2-3 cm thick, and subjecting to fruiting management; and (v) carrying out first, 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.
