摘　　要：[目的]研究不同施药量及喷雾压力对农药在苹果树上沉积的影响。[方法]3种施药量、3种施药压力喷施农药时测定农药在苹果叶片沉积量和地面流失量。[结果]在试验范围内,3种施药量下农药在叶片上的沉积量差异不大,地面流失量随施药量的增加而增加;低压力下施药有利于农药沉积。[结论]农药施用量和压力对沉积量均有影响,适当减少农药施用量、降低施药压力可增加沉积量。[Aims] It was to study the effects of different spray volume and pressure on the deposition of pesticides on apple leaves and ground.[Methods] Three spray different volumes and three different pressures were evaluated for the deposition of pesticides on apple leaves and the ground.[Results] The deposition of pesticides on apple leaves did not differ significantly at the experiment limits,while the run-off increased with the spray volume.Furthermore,the low spray pressure was favorable to the deposition of pesticides.[Conclusions] The deposition of pesticides was affected by spray volume and pressure.Reducing the spray volume and pressure appropriately could increase the deposition of pesticides on apple leaves.
