菌种质量好坏,对食用菌产量和质量影响极大。可用以下方法鉴别其优劣。外观鉴定:优良菌种的菌丝洁白、健壮、气生菌丝繁茂,无杂菌,不干涸,不积水,不出菇蕾或耳芽,培养容器小破裂。但不同种类的菌种在外观上也有差异,如:平菇的气生菌丝异常繁茂,常爬满培养容器的空间,而香菇的气 The quality of bacteria is good or bad, great impact on the yield and quality of edible fungi. The following methods can be used to identify its advantages and disadvantages. Appearance identification: fine strains of mycelium white, robust, aerial mycelium lush, non-bacteria, do not dry, no water, no Gulei or ear buds, culture container rupture. However, different types of species also have differences in appearance, such as: Pleurotus ostreatus mycelium unusually lush, often covered with space for training containers, and mushroom gas
