众所周知,食用菌栽培袋在装料时,袋口一端要用力拉住才能压紧、压实培养料,此端常常会有变形现象.笔者在此介绍一种简单可行有效防变形之法,在装料前将聚丙烯袋在120℃的高温高压下预蒸20分钟,对于聚氯乙烯袋可在0.5％的食盐水中煮50～40分钟,水沮保持80～90℃,或在常压下(100℃)蒸1.2小时左右,晾干或烘干,均可收到在装料时不变形的效果。采用上述方法不仅能提高袋的韧性,且袋能反复使用多次。
As we all know, edible mushroom cultivation bags in the loading, one end of the pocket to pull hard to squeeze, compaction culture material, this end often have deformation phenomenon. I hereby introduce a simple and effective anti-deformation method, at Prior to loading, the polypropylene bag is pre-steamed at a high temperature and pressure of 120 ° C for 20 minutes, in a polyvinyl chloride bag for 50-40 minutes in 0.5% brine, 80-80 ° C in water, or at atmospheric pressure (100 ℃) steam for about 1.2 hours, dry or drying, can receive the effect of deformation without loading. Using the above method can not only improve the toughness of the bag, and the bag can be used repeatedly many times.
