过去,我们由于缺乏生产经验,白僵菌的污染问题一直没有解决。遵照毛主席关于“要认真总结经验”的教导,近年来我们在生产中不断地研究和改进了生产工艺,基本控制了杂菌污染。具体做法是: 1.菌种虫体回接复壮白僵菌经人工多代繁殖,菌种逐渐退化。主要表现:菌丝生长不良,生活力减弱,孢子量降低,对害虫致病力弱,容易感染杂菌等。
In the past, due to the lack of production experience, the problem of Beauveria bassiana pollution has not been solved. In accordance with Chairman Mao’s teaching on “to conscientiously sum up experiences”, in recent years we have continuously studied and improved the production process in production and basically controlled the contamination of bacteria. The specific approach is: 1. Bacterial species back to Beauveria bassiana multiply multiply by artificial, gradual degradation of bacteria. The main performance: mycelium poor growth, weakened viability, reduced spore amount of pathogenicity of pests weak, susceptible to bacteria and so on.
