NOVELTY - Culture material comprises 35-70 pts. wt. mushroom residue, 30-35 pts. wt. horse dung, 0.5-1.5 pts. wt. ammonium hydrogen carbonate, 1-1.5 pts. wt. potassium phosphate, 1.5-2 pts. wt. ammonium sulfate, 1-1.5 pts. wt. lime, 0.5-1 pts. wt. golden cypress, 1.5-2.5 pts. wt. calcium superphosphate, 0.5-1.5 pts. wt. humic acid, 1-2 pts. wt. rapeseed meal, and 1-2 pts. wt. rice bran.    USE - The culture material is useful in method for cultivating H.marmoreus (all claimed).    ADVANTAGE - The culture material increases yield to 30-35% and is environmentally-friendly.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for cultivating Hypsizigus marmoreus, which involves (a) crushing mushroom residue and rice straw, and drying the crushed materials, (b) pre-wetting horse dung for 3-4 days, mixing with mushroom residue, forming heap, turning the mixture when reactor temperature reduced to 70-74 degrees C, adding golden cypress, rice bran and rapeseed meal when turning for first time, ammonium hydrogen carbonate, potassium phosphate, and ammonium sulfate when turning for second time, adding humic acid and superphosphate when turning for third time, and adjusting pH to 6.5-7.5 and moisture content to 60-65%, (c) spreading the culture material obtained in step (b) evenly into bed, sealing, maintaining 60-70 degrees C for 8-9 hours, cooling to 45-55 degrees C, maintaining 30-40 degrees C for 3-4 days, and opening doors and windows after 12 hours to keep cool, (d) removing impurities, leveling material surface to 20-25 cm thickness, opening doors and windows, and maintaining 25-30 degrees C, (e) spreading spawn evenly to first two-third portion of the surface, covering 0.5-1 cm with the culture material, sterilizing using lime, closing doors and windows for 3-5 days, and maintaining 23-27 degrees C and 70-75% relative humidity, and (f) maintaining soil thickness to 3-3.5 cm during 15-20 days after casing, maintaining 23-27 degrees C and 75-85% relative humidity, cooling two-thirds of soil to 20-23 degrees C, maintaining 80-90% air humidity, ventilating for 1-2 times a day for 1-2 hours for each time, and harvesting when grows to 3-4 cm.
