新型手动喷雾器田间应用研究及推广前景

The field application and extension foreground of the new models of manual sprayer

用不同机型的手动喷雾器喷雾同浓度的孢子液.以靶标作物叶表药液接收量、喷雾均匀度、防治效果作为衡量喷雾质量的指标,结果表明:新型手动喷雾器(PB-16型、卫士- 16型)显著优于传统的工农-16型手动喷雾器。在生产上应大力推广PB-16型、卫士-16型以替代工农-16型手动喷雾器。

In our field experiments, we used different model of manual sprayers with the same concentration of spore suspension and used the foliar surface acceptance of suspension, spraying e-quality and control effect as guidelines. The results showed that these new models of manual sprayer (model PB-16 and Weishi-16) had remarkable advantages compared with the classical manual sprayer (model Gongnong-16). We suggested wide extension of using those new models of manual sprayer instead of model Gongnong-16.
