NOVELTY - Cultivating Pleurotus nebrodensis comprises (i) taking corn cob, bean cake, mushroom stalk, lime and gypsum; (ii) adding water to mushroom stalk particles, soaking, adding the slag leaching solution along with mushroom with corn cob and bean cake, mixing uniformly, piling to form trapezoidal stack, controlling dry weight of culture material in each stack to 300-500 kg, forming a vertical vent plug using wooden stick, controlling porosity, covering with a grass thatch, and naturally fermenting, and (iii) turning; (iv), seeding and inoculating; and (v) managing mushroom fruiting stage.    USE - The method is useful for cultivating P. nebrodensis (claimed).    ADVANTAGE - The method: promotes beneficial microorganism reproduction; improves the microbial florae in materials; accelerates catalytic decomposition of cultivation materials as a soaked Lentinula edodes stem material and cultivation raw materials are mixed and piled to ferment; produces the fermented cultivation materials, which are rich in active beneficial bacterium and active metabolite of the active beneficial bacteria and have a growth promoting effect on P. nebrodensis hyphae; can strongly grow the hyphae, which are high in infectious microbe resistance; harvests the P. nebrodensis after second boom and the third boom; promotes the formation of P. nebrodensis primordial and growth of sporocarp; has biotransformation efficiency; saves the labor and the resource, e.g. coal; reduces the environment pollution; and achieves the low-carbon environment protection idea.    DETAILED DESCRIPTION - Cultivating Pleurotus nebrodensis comprises (i) taking 74-80% corn cob, 12-16% bean cake, 3-4% mushroom stalk, 4-5% lime, and 1% gypsum, where the corn cob is crushed into the particle size of 3-5 mm, and the mushroom stalk is waste produced in mushroom production process, which is dried and smashed into particle diameter of 2-3 mm, (ii) adding 20-30 times of water to mushroom stalk particles, soaking at room temperature for 18-24 hours, adding the slag leaching solution along with mushroom with corn cob and bean cake, mixing uniformly, piling to material height of 1-1.2 m and width of 2-3 m to form trapezoidal stack, controlling dry weight of culture material in each stack to 300-500 kg, forming a vertical vent plug with 10-15 cm diameter using wooden stick, controlling porosity to 1/m3, covering with a grass thatch, and naturally fermenting, (iii) when the material temperature reaches 60 degrees C, maintaining for 24 hours, turning once a day, adding lime when turning for first time, then adding gypsum when turning for second turning, turning for 3-4 times, terminating fermentation within 5-6 days, and controlling moisture content in culture material to 63-65%, (iv) cooling the fermented culture material, directly paving in furrow bed for seeding, and covering the mycelium material layer up to 1-2 cm thickness with loam soil, and (v) spraying 0.01-0.02 g/ml of mushroom stalk leaching solution after harvesting depending on mycelia growth, where the amount sprayed is 5-8 kg/cm2 and preparation of the mushroom stalk leaching solution comprises adding 20 times of water into mushroom stalk particles, soaking at room temperature for 18-24 hours, filtering the residue, making up the original amount with water, adjusting concentration to 0.05 g/ml of mushroom stalk leaching solution and diluting with water.
