当前食用菌生产一般都是从一支母种斜面开始的。在母种的分离、培养、保存过程中,或在邮递、运输、携带过程中,很可能会受到一些杂菌的污染。为使食用菌母种免遭损失,并保证其菌种的纯度,笔者针对母种不同污染情况进行了多年的纯化培养研究。现将实用的纯化技术介绍如下。 The current production of mushrooms generally start from a slant mother. In the mother’s separation, cultivation, preservation process, or in the mail, transport, carrying process, it is likely to be some of the contamination of bacteria. In order to prevent the loss of mushroom mother species, and to ensure the purity of their strains, the author of the mother of different pollution for many years of purification studies. Practical purification technology is introduced below.
