黑木耳袋栽过程中,常由于霉菌的污染而导致严重的损失。近2—3年来,仅山西的几个县就损失几百万元,使不少个体户濒于破产,这是应该引起科研单位重视和认真解决的问题。根据我们几年来的试验研究及指导基层生产的实践,对控制黑木耳袋栽过程中的霉菌污染,提以下几点浅见。一、选用优种优质菌种是发展黑木耳生产的首要条件。有了优质菌种,不重视科学保藏和合理使用也是不行的。目前有些单位对菌种长期无限制地不断移接导致其丧失原有的 Black fungus bagging process, often due to mold pollution caused serious losses. In the past two or three years, only a few counties in Shanxi Province have lost millions of dollars, leaving many self-employed families on the verge of bankruptcy. This is a problem that should arouse the attention and serious resolution of scientific research units. According to our years of experimental research and guidance of grassroots production practices, control of black fungus bags in the process of mold contamination, mention the following humble opinion. First, the selection of superior species of high quality black fungus is the development of primary conditions for the production. With high quality strains, it does not work without regard to scientific preservation and rational use. At present, some units continuously lose their long-term unlimited access to bacteria
