摘　　要：[目的]研究自走式喷雾机施药过程中不同施药方法对药剂附着率以及花生蚜虫防效的影响.[方法]喷雾时选择不同的用水量、喷头型号和工作压力,调查药液附着率和防治效果。[结果]使用XR11001型喷头、工作压力0.5 MPa、用水量5 kg的药剂附着率以及对花生田蚜虫防效相对要高,药后7 d防效可达90%以上。[结论]适当降低喷雾用水量可以提高药液的浓度、降低药液的表面张力值;选用细喷头、高压力、小水量和喷药高速度,可以明显地提高药效。[Aims]This paper aims to study the effects of different application methods on the adhesion rate of the pesticide and the control efficacy of peanut aphids during the application process of the self-propelled sprayer.[Methods]The adhesion rate and control efficacy were investigated by choosing different water consumption,nozzle models,and working pressures when spraying.[Results]By using XR11001 nozzle,working pressure 0.5 MPa,water consumption 5 kg,the adhesion rate and the control efficacy were relatively high,and the control efficacy can reach more than 90%after 7 days after application.[Conclusions]To properly reducethe water consumption can increase the concentration of pesticides and reduce the surface tension value of pesticides.The use of fine spray nozzles,high pressure,low water consumption and high spraying speed can significantly improve the control efficacy.
