用白僵菌防治马尾松毛虫是目前普遍推广使用的一种方法,具有防治费用低,使用方便,不污染环境等特点。当前生产白僵菌主要采用三级发酵培养用此方法生产的白僵菌原粉体积大,含水量高,有效保存期一般只有半年,如不及时使用就会变质失效,造成浪费。根据这一情况我们试制了“GF——80型白僵菌孢子吸附粉碎机”。该机既能粉碎白僵菌原粉,
With Beauveria bassiana prevention and treatment of Masson pine caterpillars is currently a widely used method of prevention and control with low cost, easy to use, do not pollute the environment and so on. The current production of Beauveria bassiana mainly used three levels of fermentation culture Beauveria bassiana original powder produced by this method is bulky, high moisture content, the effective shelf life is generally only six months, if not used in time will be metamorphic failure, resulting in waste. According to this situation, we trialled the “GF-80 Beauveria bassiana spore adsorption mill.” This machine can crush Beauveria bassiana powder,
