摘　　要：在室外自然条件下,开展无人机不同作业高度、飞行速度下的大田喷雾沉积试验。采用胭脂红溶液作为模拟农药,通过检测吸光度来确定喷雾沉积。结果表明,喷雾沉积一般随风速、作业高度和作业速度的增大而减少,在风速大于3.0 m/s时喷雾飘移严重;风速2.0 m/s以上时,作业高度1.5 m以上飘移严重,不宜进行小粒径低量喷雾作业。The field spraying experiments of unmanned aerial vehicles were carried out under natural conditions with different spraying heights and speeds. Carmine solution was used as an analog of pesticides and the spray deposition was determined by measuring the absorbance of sampled solutions. Results showed that spraying deposition generally decreased with the increas of wind speed, operating height and speed. There may be serious spray drift if the wind speed is more than 3.0 m/s. There may be serious spray drift if the operating height was more than 1.5 m with 2.0 m/s or higher wind speed. Soit was not suitabe for aerial spraying with small size drops under condtitions mentioned above.
