一、问题提出与研究的内容20多年来,在银耳菌种制作和栽培管理上,仍沿用着传统的分离方法和春秋两季栽培。随着菌种继代次数增多,逐渐出现了种性变异,活力降低,致使栽培过程常发生香灰菌丝衰退或死灰、不长耳等问题,直接影响银耳产量和品质,甚至遭成栽培失败。为发展生产,提高品质,必须从菌种优化入手,进一步革新生产技术,这是当前急待研究解决的问题。研究内容:包括银耳菌种中两种不同特征的菌丝,菌种衰退表现为原因分
First, the problem raised and the contents of the study Over the past 20 years, the fungus species production and cultivation management, still follow the traditional separation methods and spring and autumn and autumn cultivation. With the increase of subcultures, species variation gradually appeared and the vitality decreased. As a result, problems such as recession or ashes of mycelium of gray mycelia often occurred during cultivation, which directly affected the yield and quality of white fungus and even failed to cultivate. In order to develop production and improve quality, we must start with the optimization of strain and further innovate the production technology, which is the urgent issue to be studied and solved. Research content: Including two different characteristics of mycelium species of fungi, strain decline for the performance of points
