| 摘 要： | 以微型弹道火箭筒为发射器,将细菌（Bt )杀虫剂装入弹头,然后发射到指定的空间,瞬间破,安全防火,并定向、定点地抛撒到防治目标上,以达到防治害虫的目的。从抛撒前后对Bt的活芽孢进行测试,其结果表明前后芽孢存活率未见变化;对火箭抛撒前后Bt菌粉生物活性的研究证明,细菌（Bt )杀虫剂采用火箭抛撒剂型是可行的,实验证明经改良后的Bt菌粉用火箭抛撒,对其生物活性不但不产生不良影响,而且还具有保护和提高作用的效果。

| Abstract: | Taking the mini ballistic rocket launcher as lancher and making bullet filled with Bt powder, then the bullet is launched into the neccessary space demolishing in a twinkling safely, fireproofly, directionally and fixed positionally casted on the prevention and cure fo target for the purpose of the prevention and cure of killing injourious insect. The result of the test of living gemma of Bt powder before and after casting indicates that the living rate of gemma is no change before and after casting. And the analysis of biological active of Bt powder before and after casting by rocket proves it is possible to use rocket casting Bt insecticide powder and also proves the improved Bt powder not only has no harmful effects but also has protective and raising affect in the course of casting by rocket. |
