为提高湖南省作物病虫防治的药械整体水平 ,对国内外手动喷雾器和国产机动风送背负机两类药械的 5种机型 ,9种喷射部件和 4种喷洒方式 ,在水稻生长前、中、后期分别进行喷洒分布量试验研究 .采用纸卡法及染色剂测定法对不同药械喷洒液进行定性和定量测试 ,结果表明 ,两类药械喷洒后的沉积量、药液分布均匀性和农药利用率随水稻生育期增长而提高 ,机动风送喷洒优于手动药械喷洒 .在机动药械试验中 ,以泰山 3WF- 2 .6型非旋转喷头 ,水平沉积法喷洒效果最好 ,手动药械以西班牙产“没得比”喷洒效果最佳
In order to improve the overall level of the disease prevention and control of pesticides in Hunan Province, five kinds of models, nine kinds of injection components and four kinds of spraying methods were applied to domestic and foreign manual sprayer and domestic mobile wind-fed two kinds of drug machines, before and during rice growth , Respectively.The spray test was carried out in the later stage.The qualitative and quantitative tests of different drug sprays were carried out by paper card method and colorant assay.The results showed that the amount of chemical sprays, Rate increases with the growth of rice growth period, the mobile wind is better than manual spraying.Many tests show that Taishan 3WF-2 .6 non-rotating nozzle, horizontal deposition method is the best, “No better than” the best spray
