近几年来,一些香菇产区出现了不同程度的菌棒腐烂现象,造成了资源的浪费和菇农经济损失,局部地区已严重威胁香菇业的发展。如浙江省庆元县贤良镇1999年菌棒腐烂率达17%,个别农户达50%以上,损失惨重。对此,我们自1999年以来进行了专门的研究,初步探明腐烂的原因和防治技术。1· In recent years, a number of mushroom producing areas appeared different degrees of bacteria stick rot, resulting in a waste of resources and agro-economic losses, some areas have been a serious threat to the mushroom industry. For example, Xianliang Town, Qingyuan County, Zhejiang Province, had a bacterial stick decay rate of 17% in 1999 with more than 50% of individual farmer households suffering heavy losses. In this regard, we have conducted special studies since 1999, initially examining the causes of decay and prevention technologies. 1·
