用塑料袋取代玻璃瓶生产食用菌菌种,具有经济效益高、菌种质量好、运输方便、播种简捷、吃料快等优点,是一项值得推广应用的新技术。然而,应用不当,往往引起污染杂菌,造成严重损失。近三年多,我们对塑料袋菌种杂菌污染的原因及防止方法进行了探索,并将所得结果用于大批量生产获得成功。 一、常见杂菌污染方式及其原因 1、破袋污染 破袋污染在初次使用塑
Replacing glass bottles with plastic bags to produce edible fungus strains has the advantages of high economic efficiency, good bacteria quality, convenient transportation, simple sowing, fast feed and so on. It is a new technology worth popularizing and applying. However, improper application often causes contamination of bacteria, causing serious losses. In the past three years or so, we have explored the reasons for the contamination of bacteria in the plastic bags and the ways to prevent them, and succeeded in using the results for mass production. First, the common bacteria contamination and its causes 1, broken the bag pollution Pollution in the first use of plastic
