在生产食用菌种中,由于常常发生不定殖现象,给菌种生产厂家造成了不少损失,我所菌种厂在一九八五年春生产黑木耳枝条菌种时,发生了上万瓶菌丝不定殖现象,遭受了很大的经济损失。为了弄清原因和找出比较经济的解决办法,曾作了多次探讨,现简述如下。不定殖原因在菌种生产中不定殖的原因较多,主要有以下几种: 一、培养料水分不足。水分是食用菌赖以吸收营养物的溶剂,如果水分不足,培养料过干,接种后菌种不易吸收到含有营养的水分,因而被干死。我所在生产黑木耳菌种中,一次用的陈枝条(按理能用陈枝条,因杂菌感染多,但为了减少浪
In the production of edible fungi species, due to the frequent occurrence of non-colonization phenomenon, to the strain manufacturers caused a lot of losses, my plant in the spring of 1985 black fungus twig strains, the occurrence of 10,000 strains of bacteria Silk does not colonize the phenomenon, suffered a great economic loss. In order to understand the causes and to find more economical solutions, we have made many discussions and are summarized as follows. Reasons for not colonizing strains in the production of colonization for many reasons, mainly in the following categories: First, the lack of training material moisture. Moisture is the solvent on which edible mushrooms absorb nutrients. If the water is insufficient, the culture material will be over-dried. After inoculation, the bacteria will not easily absorb nutrients that contain nutrients and will be dried up. I am producing the black fungus species, once used Chan branches (reason to use Chan branches, due to bacterial infections, but in order to reduce the waves
