自1960年以来,在四川銀耳主要产地——通江地区,开始采用銀耳菌种的人工接种,改变了过去“靠天接种”的繁殖生产方式。人工接种具有生长快、产量高、貭量好的优点。但由于供应生产用的菌种系采用洋菜固体培养,存在着生产較慢、手續繁、成本高等問題,因而还未能在該地普遍推广。为了解决上述存在問題,笔者曾于1962年改洋菜固体表面培养为 Since 1960, artificial inoculation of Tremella species has started in the Tongjiang area, the main source of white fungus in Sichuan, which has changed the mode of breeding production that was “vaccinated by the sun” in the past. Artificial inoculation has the advantages of fast growth, high yield and good quality. However, due to the use of Agrobacterium tumefaciens for the production of bacteria, there is a problem of slow production, complicated procedures and high costs, and thus it has not yet been widely promoted in this area. In order to solve the above problems, I had in 1962 to cultivate foreign culture solid surface
