喷杆式喷雾机雾滴飘移测试系统研制及性能试验

为了测试并分析雾滴的实时飘移情况及飘移分布规律，该文研发了一套雾滴飘移测试系统，用于研究不同喷雾设备喷雾时产生的雾滴飘移特性并评价其飘移潜力。依照国际飘移分级标准ISO22369-2-2010，在室内环境条件下对喷杆式喷雾机上6种扇形雾喷头的雾化性能参数进行了测试，对其飘移特性进行了对比试验并评价其飘移潜力dPV。结果表明：喷头与工作压力对飘移潜力影响显著（P〈0.05）。喷雾压力为0.3MPa时，常规喷头XR110-04的飘移潜力最高，为33%。ID、IDK等气吸式喷头飘移潜力明显小于常规喷头（P〈0.05）。LechlerID120-025喷头的飘移潜力最小，仅为6%。提高喷雾压力会使飘移...

Summary:为了测试并分析雾滴的实时飘移情况及飘移分布规律，该文研发了一套雾滴飘移测试系统，用于研究不同喷雾设备喷雾时产生的雾滴飘移特性并评价其飘移潜力。依照国际飘移分级标准ISO22369-2-2010，在室内环境条件下对喷杆式喷雾机上6种扇形雾喷头的雾化性能参数进行了测试，对其飘移特性进行了对比试验并评价其飘移潜力dPV。结果表明：喷头与工作压力对飘移潜力影响显著（P〈0.05）。喷雾压力为0.3MPa时，常规喷头XR110-04的飘移潜力最高，为33%。ID、IDK等气吸式喷头飘移潜力明显小于常规喷头（P〈0.05）。LechlerID120-025喷头的飘移潜力最小，仅为6%。提高喷雾压力会使飘移潜力变大。研究结果可为减少雾滴飘移的施药技术研究与飘移分级的制定提供参考。

The use of pesticides is an important part of modern agriculture and contributes to the productivity and the quality of the cultivated crop. Pesticide exposure via spray drift can have a negative impact on bystanders, residents, livestock, terrestrial and aquatic ecosystems.Several reviews related to drift phenomenon have been published since the negative effect of spray drift has been recognized. Spray drift is affected by environmental and meteorological conditions, the spray technique and the crop. Wind speed and wind direction are meteorological factors affecting spray deposition. Relative humidity and high air tempe
