NOVELTY - Cultivation of Hypsizygus marmoreus comprises preprocessing powder residue comprising sweet potato or mung bean production waste; uniformly mixing powder residue, matrix material, urea, composite fertilizer, lime and ash; adjusting water content and pH of mixture, stacking, and fermenting; putting obtained culture medium in a bag and inoculating H. marmoreus strain; stacking mushroom bags in fermentation room, controlling temperature and humidity, and reverse stacking every 8-11 days; and controlling room temperature and humidity, maintaining room ventilation, and refruiting.    USE - Method for cultivation of H. marmoreus (claimed).    ADVANTAGE - The method is simple, improves H. marmoreus production, and solves the problem of environment pollution by using the powder residue and waste. The powder residue can be used as fertilizer after using. By using powder residue, the cost of culture medium is reduced.    DETAILED DESCRIPTION - Cultivation of H. marmoreus comprises: (A) adding calcined lime to powder residue comprising sweet potato or mung bean production waste to adjust pH to 7-10 and exposing to sun or drying until water content of 15-20 wt.%; (B) uniformly mixing 5-20 pts. wt. powder residue, 70-85 pts. wt. matrix material comprising cottonseed hulls or crushed corn stalks, 0.3-0.5 pts. wt. urea, 2-4 pts. wt. composite fertilizer, 2-5 pts. wt. lime and 1-2 pts. wt. ash; (C) adjusting water content of mixture to 65-70 wt.% and pH to 7-8 with limewater, stacking while providing a vent hole at the top of every 25-30 cm stack, and fermenting for 6-8 days while turning 3-4 times to obtain culture medium; (D) putting culture medium in polyethylene bag, inoculating 8-12 wt.% H. marmoreus strain, sealing bag opening, and pricking vent holes; (E) stacking mushroom bags in fermentation room, controlling temperature at 20-25 degrees C and humidity at 50-60%, and reverse stacking every 8-11 days; and#controlling room temperature at 15-18 degrees C and humidity at 85-95%, maintaining room ventilation, refruiting 2-3 stubble after 2 complete cropping of mushroom.
