NOVELTY - Pleurotus nebrodensis mushroom cultivating material comprises: 40-50% tea seed meal, 15-25% fresh tea meal, 12-18% corn cob, 12% rice bran, 5% soybean meal, 2% gypsum powder and 2% lime powder. The tea seed meal is prepared by drying tea seed shell, crushing into particles with particles.    USE - As Pleurotus nebrodensis mushroom cultivating material (claimed).    ADVANTAGE - The cultivating material has reasonable thickness and improves the air permeability and water (corn core culture material strong in water preserving property), shorten pleurotus nebrodensis mushroom mycelium growth speed, and bag time; is good for mycelium to absorb simple substance, promotes the formation of Pleurotus nebrodensis mushroom fruit body original base to make a mushroom number, increased production by 20-25%, where widens the planting raw material, greatly reduces the production cost.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of Pleurotus nebrodensis mushroom cultivating material involving: solarizing raw material for 1-2 days using ultraviolet killing raw material in a mixed fungi; prewetting by the tea seed meal, fresh tea dust in a dry state under uniform stirring, carrying out pre-wet with 1% lime water solution (wet completely), stacking ferment the wet material with piling height of 1-1.2 m, width of 2-3 m, and length with ladder-shaped stack, each stack of the culturing material in a dry 300-500 kg, after finished, the surrounding light, and by the diameter of stick is 10-15 cm which is inserted in some air holes in the stack through the stack, air hole density of 1 m3, at last cover the upper part of the tarpaulin to make it natural ferment, and turning the material temperature reaches to 60 degrees C, keeping for 24 hours, then carrying out, and every day turning the first time, when turning on the third time adding corn core, rice bran, soybean meal, plaster powder and so on, and adding water at turning time of 4-5 times, and for 6-7 days, stopping fermenting to obtain culture material with water content of 63-65%; bagging: taking 17x 35x 0.005 cm polypropylene plastic bag, each bag with 1100-1200 g wet material, where the mounting material and a suit of lantern ring, is inserted into the plastic bolt. The sterilizing and cooling of the material is carried out at normal pressure sterilization, when the temperature in pot reaches to 100 degrees C and discharge cooling gas, keeping for 10-12 hours, then naturally cooling to be lower than 25 degrees C.
