【摘要】 本文报道了白僵菌混合粉剂工业化生产的工艺流程。经中试试验,所得产品的理化参数符合规定要求。产品经充氮包装,室温下贮藏半年后的萌发率为70.56%,而没有制剂的孢子粉贮藏半年后的萌发率仅为30.96%。产品的亩用量为20～25g,使用成本为13.5～16.9元/hm~2。更多还原

【Abstract】 In the present paper,the mass production technology of a mixed dust formulation of B.bassiana was reported.The physical and chemical indexes of the pilot products were optimal for storage and application.The germination rates of the conidia formulated and then charged with nitrogen were 70.56%after stored for half a year,while the unformulated conidia was 30.96%in contrast.The application cost reached 13.5～16.9RM ?/hm~2 when 300- 375g of dust was sprayed 1hm~2.更多还原
