摘要
１９８０年白僵菌低热风烘干房设计成功投入使用，解决了白僵菌产品不能及时干燥，特别是阴雨天气导致变质的技术难关，比自然干燥功效提高４倍，产量提高２倍以上；１９８８年机械分离提取白僵菌孢子粉生产工艺获得成功，孢子粉提取率为６．９％～６．８％，孢子回收率７９．８％～８１．３％，产品合孢量１０００亿／ｇ以上，孢子发芽率９５％以上。目前，白僵菌年生产能力达２５ｔ以上。１９７９～１９９１年共生产白僵菌２３８．１５ｔ，防治松毛虫７９９０．８ｈｍ２，防治效果６６．２３％，挽回经济损失２１９．１１万元，是经费总投入１１．３３万元的１９．３４倍。
Successful design and put into production in 1980 of drying chamber with low heat wind resolved a problem that muscardine product could not dried in time,especially in rainy days.Efficacy or this method was 4 times of that by natural drying,output was over 2 times.In 1988,extraction of muscardine spore by mechanical separation achieved succeed,extraction rate reached 6. 5%～6.8%,recovery rate of spore was 79.8%～81.30%,spore content in product was over 100 billior/g,spore germination rate reached over 95%.At present,annual capacity of muscardine was over 25t.From 1979 to 1991,muscardine production totaled 238.15t to control7990.8 hectare pine forest,control effect reached 66.23%.
