在食用菌制种中,常常发生不定殖(即菌丝不萌发,不“吃料”)现象,给菌种生产造成了很大损失。造成不定殖的原因及其对策主要有以下几种: 水分是菌丝体吸收营养物质的溶剂,如果水分不足,培养基过干,接种后菌种不容吸收到含有营养物的水分,因而被干死,故不能发菌。对策是:在配料时,按水分要求,严格按规定量器加水,边加水边搅料,
In the edible fungus species, often unfamiliar (ie mycelium does not germinate, not “feed”) phenomenon, resulting in a great loss of strain production. The causes of non-colonization and its countermeasures mainly include the following: Moisture is mycelium to absorb nutrients in the solvent, if the water is insufficient, the medium is too dry, after inoculation strains can not absorb moisture containing nutrients, and was dry Dead, it can not send bacteria. Countermeasure is: In the ingredients, according to the water requirements, in strict accordance with the provisions of measuring instruments add water, while adding water edge stir,
