我县自推广袋栽黑木耳技术以来,栽培面积逐年扩大,杂菌污染也较严重,给耳农带来了一定的经济损失.为此,近几年来我们在栽培过程中,对杂菌的污染进行了重点探索,现就杂菌污染的原因及防治措施谈点浅见.(一)灭菌不彻底污染的杂菌,最常见的是霉菌.我区菇农大多是采用常压灭菌,因锅封闭不严,锅内装料又较多,常常灭菌不透,幸存的霉菌孢子萌发繁殖造成料袋污染.灭菌不透的料袋(17×35cm),接种
Since the popularization of bagged black fungus technology in our county, the area of cultivation has been expanded year by year, and the pollution of other bacteria is also serious, which brings some economic losses to the ear growers.In order to do this, in the recent years we cultivated the fungus Pollution has been the focus of exploration, is now on the causes of bacterial contamination and prevention measures Talk about the point of view. (A) bacteria are not thoroughly contaminated, the most common is mold .Mushroom industry in my area are mostly using atmospheric sterilization, Due to lame pot is not strict, the pot is filled with more often impermeable bacteria, spores germinate surviving germination caused by bag contamination. Sterile impervious material bag (17 × 35cm), inoculation
