近年来,闽、江、浙、沪等地利用棉籽壳制蘑菇菌种,既提高了棉花副产品的利用率,又提高了制种质量。一瓶棉壳菌种,相当于两瓶粪草菌种,且掏瓶、播种方便。但是这种方法培养料发酵时间长、养分损失多,推料、翻料所需劳力多,生产工艺复杂,环境污染严重,受气候影响较大,菌种质量不稳定。为此,笔者自1990年2月开始进行棉壳 In recent years, Fujian, Jiangsu, Zhejiang, Shanghai and other places using cottonseed mushroom strains, not only improve the utilization of cotton by-products, but also improve the quality of seed production. A bottle of clostridium species, equivalent to two bottles of feces, and dig bottle, sowing convenience. However, this method of culture material fermentation time, nutrient loss and more push, turn over the labor required, the production process is complex, serious environmental pollution, affected by the climate, strain quality instability. To this end, the author since February 1990 for the cotton shell
