在产棉区，用棉子皮栽培食用菌已收到了可观的经济效益，但大量的棉秆在农村都白白的烧掉或烂掉了，实在可惜。笔者在发展食用菌生产时，利用当地资源优势，进行了棉秆屑作培养料栽培灵芝的尝试，连续两年产量和质量都取得了较好的效果。现将其技术要点介绍如下：１原料处理选 In the cotton producing area, cultivation of edible mushrooms with cotton seed skin has received considerable economic benefits, but a large number of cotton stalks burned or rotted in the countryside are white, it is a pity. In the development of edible fungus production, the author made use of the advantages of local resources to carry out the cultivation of Ganoderma lucidum with cotton straw as the cultivation material, and achieved good results in yield and quality for two consecutive years. Now the technical points are as follows: 1 raw material processing election
