工欲善其事,必先利其器。有了药效良好的衣药,还必需有性能优良的施药器械,才能及时消灭病虫害。近几年来,我国科学研究工作者,在总结农民群众治螟经验的基础上,设计成功一种泼浇机。它能使药液像雨一样落到水稻上,防治螟虫效果很好。我国原来采用的治螟药械,如手动喷雾器和手动喷粉器,效率都不很高,耗费劳动力较大。我国农民就自己摸索出一些施药方法,其中效果最显著的一种是泼浇,它对枯心苗和白穗的防治都很有效。农民挑着配好的六六六药液,用粪杓 If a worker wants to do good, he must first sharpen his tools. With good drug efficacy, it is also necessary to have excellent application equipment for the timely elimination of pests and diseases.
