以从大麦芽粉、麸皮、土豆等农副产品中提取出的营养物质制备成的营养浸膏所配制的母种培养基，对平菇、香菇、木耳菌丝体的培养试验结果表明，用土豆浸膏作为主要营养物质直接配制的ＰＤＡ 培养基与常规方法配制的ＰＤＡ 培养基，具有相同的食用菌菌丝体培养效果；对平菇和香菇来说，制备的几种营养浸膏作为主要营养物质配制的母种培养基的菌丝体培养效果均不亚于用常规方法配制的ＰＤＡ 培养基，木耳的情况也基本如此。
The results of culture experiments on Pleurotus ostreatus, Mushrooms and Pleurotus ostreatus with the mother culture medium prepared from the nutritional extracts prepared from the nutrients extracted from agricultural products such as barley malt flour, bran, potatoes and the like, Potato extract as a major nutrient directly formulated PDA medium and conventional methods of PDA medium formulated with the same edible mushroom mycelium culture; mushrooms and mushrooms, the preparation of several nutritional extracts as the main The mycelium culture effect of the mother culture medium formulated with nutrients is no less than that of the PDA culture medium prepared by the conventional method, and the case of the fungus is also basically the same.
