喷雾参数对雾滴飘移性能影响的试验研究--基于风幕式喷杆喷雾机

摘要

飘移是评价农药喷雾效果的重要指标。在室内封闭宽敞的环境下测量风幕式喷杆喷雾机在不同的喷雾工作参数下的飘移率指标，为风幕式喷杆喷雾参数的优化和防飘喷雾技术的研究提供理论依据。结果表明：喷头喷施角对飘移率指标有显著的影响，改变喷头与风幕的水平和垂直距离或风机频率对雾滴飘失的影响相对于喷施角度的改变都不显著。%spray drift is one of the most important indexes evaluating spray effect .Air curtain boom sprayer ’ s drift rate indexes are measured in different spray parameters in closed indoor spacious environment , which provides theoretical ba-sis for the optimization of spray parameters and the study of anti-drift spray technology .The results show that the nozzle ’ s spraying angle has a significant impact on the drift rate indexes , while relative to the changes of the spraying angle , the changes of horizontal and vertical distances between the nozzle and air curtain and the blower ’ s frequency do not influ-ence spray drift significantly .
