食用菌菌种在多年使用后,产量、品质常有退化现象。在生产中,常见的克服方法,是配制营养优良的培养基、避免长期连续转管等。作者认为,通过有性繁殖选育后代也是一种有效手段,其具体操作由单孢分离、初生菌丝交配、栽培选育几个主要环节组成。 一、材料与方法 (一)供试菌种 平菇中蔬10号,引自九江国棉一厂食用菌菌种厂,种植6年,产量下降,有畸形菇出现。 After years of use of mushroom strains, the yield and quality often degenerate. In production, the common way to overcome is to formulate nutritionally-rich medium to avoid long-term continuous tube-transfer and the like. The author believes that sexual reproduction breeding of offspring is also an effective means of its specific operation from the single spore separation, primary mycelium mating, cultivation and breeding of several major components.
