袋栽木耳是东北地区木耳生产的主要栽培方式.据调查,不少专业户及部分食用菌厂,因多种原因常有大批菌袋不能在冬前出耳.笔者在室内进行加温出耳试验表明,不仅投资大,管理复杂,且出耳期杂菌污染率在18%以上,比常规栽培减产28.7%.针对这一问题,我们于1989～1990年进行了菌袋越冬保存至次年春季出耳的试验,摸索菌袋越冬保存的可行性,为生产提供科学依据,现将结果报告如下:
Bag fungus is the main cultivation of fungus production in the northeast region.According to the survey, many professional households and some edible fungi factory, due to a variety of reasons often a large number of bacteria bags can not be ear before winter.I author indoors heating ear test The results showed that not only the investment is large and the management is complex, but also the earring bacteria contamination rate is over 18%, which is 28.7% less than the conventional cultivation.In response to this problem, we carried out the winter germ bag overwintering from 1989 to 1990 Ear of the experiment, to explore the feasibility of overwintering the storage of bacteria bags for the production of scientific basis, the results are reported as follows:
