笔者保存的香菇菌株有60～70株。过去均用PDA培养基斜面试管冰箱保存,每年转管2～3次,这样做颇感费时花工。为减轻工作量,于1983年12月2日开始探索用木屑培养基试管保存。经观察初步表明,采用木屑试管种在冰箱中可保存两年。现将结果简报如下; 一、材料与方法 The author preserved mushroom strains of 60 to 70 strains. Past use of PDA medium slope tube refrigerator preservation, transfer tubes 2 to 3 times a year, this is quite time-consuming to do the work. In order to reduce the workload, we started to explore the preservation of tube with sawdust medium on December 2, Preliminary observations show that the use of wood chips in the refrigerator can be stored for two years. Now the results briefings are as follows; First, materials and methods
