| 摘 要： | 为明确适用于植保无人飞机施药模式下农药残留试验的田间采样方法，本研究探究了最佳施药条件下Z字形法、棋盘法、对角线法及米字形法4种采样方法及不同采样点数下的雾滴密度分布情况，并对由采样方法引入的不确定度进行了评估。结果表明，T30型植保无人飞机的最佳作业参数为：飞行速度3 m/s，飞行高度为距作物冠层2 m，作业间距为5 m；植保无人飞机喷雾作业区域外围的喷雾沉积量对区域平均喷雾沉积量变动影响较大，因而其残留样品采集时应尽量避免从施药作业区域外围采集；为了增加植保无人飞机施药模式下田间样品采集的均匀性和代表性，建议采样点数应设置在18个点及以上，并可选用对角线法、棋盘法或Z字形法采样。

| Abstract: | In order to clarify the field sampling methods suitable for pesticide residue testing under the application mode of unmanned aerial spray system (UAS) for plant protection, this study explored the four sampling methods, Z-shaped method, checkerboard method, diagonal method, and '米'-shaped method, under optimal application conditions, and the density distribution of droplets under different sampling points, and evaluated the uncertainty introduced by the sampling methods. The results show that the optimal operating parameters of T30 plant protection UAS were: flight speed of 3 m/s, flight altitude of 2 m from crop canopy, and working distance of 5 m. The spray deposition content at the periphery of the spray operation area of the plant protection UAS has a great influence on the change of the average spray deposition content in the region, and the residual samples should be collected as much as possible to avoid collecting from the periphery of the application operation area. In order to increase the uniformity and representativeness of field sample collection in the application mode of plant protection UAS, it is recommended that the number of sampling points should be set at 18 or more, and the diagonal method, checkerboard method or Z-shaped method can be selected. |
