我县自1984年推广袋栽黑木耳技术以来,栽培面积不断扩大,袋数日益增加,但霉菌为害也日趋严重,仅1985年栽培15000袋,污染率达60％,尤其在出耳期,一旦发生霉菌,轻者减产,重者绝收。为此,几年来我们对袋装栽黑木耳易霉染的原因及防治霉染的措施进行了试验研究,取得了较好的效果。1987年栽培3500袋,污染率下降到15％;1988年栽培4500袋,污染率只占10％,现提出以下几点浅见。
Since the popularization of bagged black fungus technology in 1984, the area of cultivation has been continuously expanded and the number of bags has been increasing. However, the mold damage has also become increasingly serious. In 1985, 15,000 bags were cultivated with a pollution rate of 60%, especially in the ear. Molds occur, the light production cuts, those who receive the worst. To this end, the past few years, we planted black fungus susceptible to mildew and its prevention and control measures mildew were tested, and achieved good results. In 1987, 3,500 bags were cultivated, and the pollution rate dropped to 15%. In 1988, 4,500 bags were cultivated, accounting for only 10% of the pollution rate. The following opinions are put forward.
