香菇塑料袋制种,经过高压灭菌,袋子往往胀气破裂。聚氯乙烯袋消毒后不脆化,但具有毒性。聚丙烯袋虽无毒,消毒后则脆化脱壁,易引起杂菌污染。加之上海制备香菇栽培种时正值高温季节,空气中杂菌孢子基数大,萌发条件适宜,对塑料袋制种带来不便。为了防治污染,提高塑料袋制种的成品率,我们作了各种单因子试验,结果如下: (一)消毒时间塑料袋料重比瓶装多2～2.5倍,用进口的聚丙烯塑料制袋,按常规木屑培养料的配方,每袋湿料1.8斤,消
Mushrooms plastic bags, after sterilization, bags often flatulence rupture. PVC bags are not brittle after disinfection, but toxic. Although non-toxic polypropylene bags, after disinfection embrittlement off, easy to cause bacterial contamination. Coupled with the preparation of mushroom cultivation in Shanghai at a time when the hot season, the air bacteria in the spore base, suitable germination conditions, the inconvenience of plastic bagging. In order to prevent pollution and improve the yield of plastic bags, we made a variety of single-factor tests, the results are as follows: (a) disinfection time plastic bag material weight more than 2 to 2.5 times the bottle, with imported polypropylene plastic bag , According to the conventional wood flour material formula, 1.8 kg per bag of wet material, consumer
