食用菌菌种生产是一种广谱性技术。自人工栽培菌种以来,已研究发展了几十年,生产技术日趋成熟,经历了从广口瓶生产栽培种到塑料袋生产栽培种的演变。但是,不少生产者的菌种成品率偏低,特别是黑木耳,一般只有70%～80%,有的甚至不足50%,不仅经济损失较大,菌种生产者的生产积极性也受到挫伤。 Edible fungus species production is a broad spectrum of technologies. Since the artificial cultivation of bacteria, research and development has been for decades, the production technology matures, has gone through the production of jars from the cultivation of plastic bags to the evolution of cultivars. However, the production rate of many producers is low, especially the black fungus, which is generally only 70-80%, and some is even less than 50%. Not only the economic loss is large, but also the producers’ enthusiasm for production is dampened .
