NOVELTY - Production of Agrocybe cultivation material involves, (a) using cottonseed hull, tea seed meal, mushroom tang, lime and calcium carbonate, (b) adding water to mushroom tang particles, soaking, mixing with cottonseed hull and tea seed meal, piling mixture, plugging vertical sticks in pile, and naturally fermenting, (c) turning fermented material with addition of gypsum and light calcium carbonate, and (d) cooling fermented material, loading in polyethylene bags, inoculating and culturing strain in dark room, and managing fruiting.    USE - Production of Agrocybe cultivation material (claimed).    ADVANTAGE - The method uses mushroom tang, which is a natural nutrient solution containing a wide variety of bioactive substances, promotes beneficial microbial growth, improves feed microflora, accelerates catalytic decomposition of cultivated material, promotes mycelium growth of mushroom, saves manpower, coal and other resources, is environmentally-friendly, and meets low-carbon environmental requirements.    DETAILED DESCRIPTION - Production of Agrocybe cultivation material, involves (a) using 76-82 %mass cottonseed hull, 12-16 %mass tea seed meal, 3-4 %mass mushroom tang obtained by drying and pulverizing production waste to particles of 2-3 mm, 2-3 %mass lime and 1 %mass calcium carbonate, (b) adding 20-30 times water to mushroom tang particles, soaking for 18-24 hours at room temperature, mixing cottonseed hull and tea seed meal with soaked solution, piling the mixture to a height of 1-1.2 m, a width of 2-3 m, and a dry weight of 300-500 kg, patting for 4 weeks, plugging 10-15 cm vertical sticks in the pile at 1/m3, covering with grass thatch, and naturally fermenting, (c) turning the fermented material once every day 3-4 times for 5-6 days when the temperature reaches 60 degrees C and is maintained for 24 hours, while adding gypsum during first turning and light calcium carbonate during second turning, and terminating fermentation to obtain a material with a moisture content of 63-65%, and (d) cooling the fermented material, loading in 17x 35x 0.004 cm polypropylene bags, marking inoculation holes, inoculating strain in each bag, culturing bacteria in dark room at 20-22 degrees C and 60-75% humidity for 22-24 days, and managing fruiting.
