随着香菇栽培面积的不断扩大,菌种生产量也在急剧增加。由于一些菇农还是沿用传统制作三级种的方法和不规范的操作规程,致使生产出的菌种菌龄差异大,生长周期长,菌种质量上下不一致,上部较好,中下部缺氧,内含隐性杂菌等,造成巨大的经济损失。我们针对这一问题进行了试验摸索,成 With mushroom cultivation area continues to expand, bacterial production is also rapidly increasing. Because some mushroom farmers still follow the traditional method of producing three kinds of species and non-standard operating procedures, resulting in bacterial strains of different ages, long growth cycle, the quality of the upper and lower inconsistencies, the upper is better, the lower anoxia, Containing hidden bacteria, resulting in huge economic losses. We conducted a trial and error for this issue
