摘要
为提高农药的有效利用率,研究雾滴大小、叶片表面性质与倾角对农药雾滴沉积量的影响,选用6种喷头ST110-01、ST110-02、ST110-03、ST110-04、ST110-05及IDK120-03,在设定叶片倾角为0°、15°、30°、45°、60°、75°时在棉花、水稻与小麦叶片上进行试验研究。结果表明:叶片表面性质、叶片倾角对沉积量影响差异显著,喷头类型,即雾滴大小,对沉积量影响不显著;减小叶片倾角有助于增加沉积量;叶片微结构可能是作物影响沉积量的原因。该研究可为农药有效利用率的提高提供参考。
Effect of droplet size,leaf characteristics and angle on pesticide deposition was investigated to increase the pesticide usage efficiency.Nozzles of ST110-01,ST110-02,ST110-03,ST110-04,ST110-05 and IDK120-03 were compared with leaf angles at 0°,15°,30°,45°,60° and 75° on cotton,rice and wheat,respectively.The results demonstrated that leaf characteristics and angle had a significant effect on deposition,while the effects of nozzle type or droplet size were not significant.The deposition increased as the leaf angle decreased.The micro-structure of leaf may cause the different deposition.The research involved in this paper will provide the valuable basis for the pesticide efficiency enhancement.
