生产木耳、香菇、双孢蘑菇等原种或栽培种,从接种培养到菌丝长满全瓶,一般都要25～40天,特别是原种生长更慢,同一瓶里不同部位的菌丝其菌龄相差悬殊,活力也各有不同。根据真菌菌丝生长的生物学特点——从接种点向周围呈球状逐步扩大,我们在生产食用菌原种、栽培种时,常常采用“两点法”接种,可使菌丝提早1/3～1/2的时间长满瓶,不仅节约时间和开支,而且菌龄较一致,活力也更强。为了说明事实,我们重新作了“两点法”接种和“一点法”(常规法)的比较试验。试验菌种为新鲜的木耳、香菇、银耳、平菇、紫晶蘑和双孢蘑菇斜面菌种各1～2管和原种各1瓶。木生菌用常规锯屑培养基,紫晶蘑和双孢蘑菇用
Production of fungus, mushrooms, Agaricus bisporus and other species or cultivars, from inoculation to grow mycelium full bottle, usually 25 to 40 days, especially the original species grew more slowly, in the same bottle of different parts of the mycelium The difference between the age of their bacteria, vitality are also different. According to the biological characteristics of fungal mycelium growth - from the point of vaccination to the surrounding spherical gradually expanded, we produce edible fungi, cultivars, often using the “two-point method” inoculation, the mycelium can be earlier 1/3 ~ 1/2 of the time full of bottles, not only save time and expenses, but more consistent age, vitality and stronger. In order to illustrate the facts, we re-made a comparative test between the “two-point law” vaccination and the “one-point law” (conventional law). Test strains for fresh fungus, mushrooms, white fungus, mushrooms, mushrooms and Agaricus bisporus bevel strains of 1 to 2 tubes and each of the original 1 bottle. Woody bacteria with conventional sawdust medium, Amethyst mushrooms and Agaricus bisporus
