近年来,我省栽培生产黑木耳污染较严重,曾造成较大的经济损失。其原因除栽培管理不善外,主要是菌种退化或菌种不纯引起的不良后果。为了选育适合我省栽培的菌株,我们于1987年从外地引进15个品种,做了比较筛选,同时采用物理化学方法进行选育。结果如表:
In recent years, cultivation and production of black fungus in our province more serious pollution, had caused greater economic losses. In addition to its reasons for poor cultivation and management, the main strain is degenerated or impure strains of adverse consequences. In order to breed strains suitable for cultivation in our province, we introduced 15 varieties from the field in 1987, made comparative screening, and used physicochemical methods for breeding. The results shown in the table:
