食用菌菌种生产,一般先由孢子分离或组织分离培育出母种,再将母种扩大到培养基上得原种,然后原种由熟料培养成生产上使用的栽培种,或称一级、二级和三级菌种。但一些适应性强、菌丝生长快的菇类如平菇、草菇、凤尾菇等,其栽培种可通过子实体直接繁殖或生料直接生产,既快速方便,又降低了成本。 一、子实体繁殖法。用菇体组织直接生产菌种,方法简单,时间短,遗传性稳定。在缺乏原种的情况下, Edible fungus species production, generally first by spore separation or tissue culture to cultivate the mother species, then the mother species expanded to the original medium on the medium, and then the original species from clinker culture used in the production of cultivated species, or a Level, two and three species of bacteria. However, some adaptable mushrooms with rapid mycelial growth, such as Pleurotus ostreatus, mushrooms and mushrooms, can be directly propagated through fruiting bodies or directly produced from raw materials, which is quick and convenient and reduces the cost. First, the sub-entity breeding method. Mushroom body tissue directly produced species, the method is simple, time is short, hereditary stability. In the absence of original species,
