在凤尾菇生产中,常碰到母种或原种在菌瓶内过早出现子实体,菌丝发生老化,影响生产效益。为了促进菌丝生长,延缓菌种老化,我们从改变菌种培养料配方入手,进行了初步探讨。 (一)材料和方法供试菌种是1982年10月从西安市农科所引入的试管种,经过瓶栽后,用菌盖进行组织分离得到母种。 In the production of Pleurotus ostreatus, often encounter the mother or the original species in the bottle early premature fruiting bodies, hyphae aging, affecting the production efficiency. In order to promote the growth of mycelium and delay the aging of the bacteria, we started with changing the formula of the bacterial culture material. (A) Materials and Methods The test species was introduced in October 1982 from the Xi’an Branch of the test tube species, after bottle planting, with a cap to separate the mother species.
