NOVELTY - A cotton straw bag-type cultivation culture material comprises 45 wt.% cottonseed meal, 15 wt.% cottonseed skin, 15 wt.% corn cob, 6 wt.% wheat bran, 6 wt.% soybean meal, 6 wt.% pure chicken manure, 1 wt.% phosphate, 1 wt.% gypsum, and 5 wt.% lime; or 15 wt.% cottonseed meal, 45 wt.% cottonseed skin, 15 wt.% corn cob, 6 wt.% wheat bran, 6 wt.% soybean meal, 6 wt.% pure chicken manure, 1 wt.% phosphate, 1 wt.% gypsum, and 5 wt.% lime.    USE - Cotton straw bag-type mushroom cultivation culture material.    ADVANTAGE - The method is simple and has clear steps and planting good effect.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for cotton straw bag-type cultivation of mushroom by:    (A) mixing cottonseed meal, corn cob and half of lime with water at ratio of 1:1.4, piling at 1.2 m high 2 m lower width, and 1.3 m upper width, fermenting to 60-100 degrees C for 24 hours, turning other side while adding remaining materials, mixing, fermenting, turning once, and bagging 20-25 wt.% material into 22 cm/asterisk46 cm polyethylene bag when temperature reaches 60?C, compacting into 2.75 kg weight of bag, and sterilizing to carry out inoculation; and placing 2 cm sticks or iron rods, or 4-5 cm long nails on edge side of bag to tie both ends and facilitate rapid growth of mycelium;    (B) mixing cottonseed meal, corn cob and half of lime with water at ratio of 1:1.4, piling at 1.2 m high 2 m lower width, and 1.3 m upper width, pre-wet fermenting to 60-100 degrees C for 24 hours, adding remaining materials, mixing for 30 minutes, bagging into 18 cm/asterisk40 cm polyethylene bag, compacting into 2.75 kg weight of bag, and sterilizing to carry out inoculation; and    (C) fruiting by (i) adjusting greenhouse temperature comprising 20 degrees C at daytime and 10 degrees C at night but not lower to 8 degrees C, stimulating strong light during daytime at 10 AM for 1-2 hours to promote formation of primordia fruiting body, and untying bag, and removing; (ii) spraying water on ground and space and not directly on fruiting body to increase relative humidity of air during budding stage, strengthening ventilation, and controlling temperature to 5-25 degrees C to promote fast growth of young mushroom; and (iii) injecting with fertilizer comprising 50 kg water, 0.4 kg urea, 0.3 kg glucose, and 1.5 kg fulvic acid after 2-3 days to improve mushroom production capacity.    The fermentation requires 4 days to complete when outside temperature is high and 6-7 days when temperature is low.
