我们通过几年来的实践,掌握了塑料袋制种的主要环节,有效地防止和控制了杂菌污染,成品率逐年提高.1986年生产香菇、毛木耳菌种共59281袋,平均成品率达95.13%。本文就塑料袋制种的技术关键介绍如下.(一)提高装袋的质量制种前要检查塑料袋是否完好无损,凡袋壁有泡点的坚决不用。袋底折角时,角度大小要适当,并要顺着压边方向折。配料的湿度,在常规湿度的前提下宜干不宜湿。装料的松紧度要适当,料面要紧而平,不能有断层,以免灭菌后 Through years of practice, we have mastered the main aspects of seed production of plastic bags, effectively prevent and control the contamination of miscellaneous bacteria, and the yield of finished products has increased year by year. In 1986, a total of 59,281 bags of shiitake mushrooms and fungus strains were produced, with an average yield of 95.13 %. This article on the plastic seed production of the key technologies are described below. (A) to improve the quality of bagging Before planting to check whether the plastic bag is intact, where the bag wall has a bubble point firmly not. Angle at the end of the bag, the angle should be appropriate size, and should be folded along the direction of the pressure side. Ingredients of humidity, under the premise of normal humidity should be dry should not be wet. The tightness of the loading should be appropriate, the material surface tight and flat, can not have faults, so as to avoid sterilization
