摘　　要：为了研究旋翼类型和喷头类型对雾滴沉积影响,针对5种电动植保无人机进行水稻田雾滴沉积分布试验研究,试验机型包括单旋翼和多旋翼,喷头类型涉及离心式和液力式,并设置15L/hm2相同施药量,研究测定各机型的有效喷幅、雾滴沉积分布和冠层间的药液沉积量。试验结果表明:单旋翼机型具有较大的有效喷幅;离心式喷头雾滴沉积粒径较小,但雾滴沉积密度更大;各机型在作物上层的雾滴分布均匀性和药液沉积量最优,中层最差;相比液力式喷头,离心喷头可以获得更好的雾滴穿透效果。Five kinds of electric drones were used to test the distribution of droplet deposition in rice fields,including single rotor and multi-rotors,centrifugal and hydraulic nozzles.The same application amount of 15 L/ha was set to study the effective spray width,droplet deposition distribution,and liquid deposition amount between rice canopy for each drone.The test results show thatthe single rotor model has a larger effective spray width;droplet size of the centrifugal nozzle is smaller,but the density is greater.The distribution of droplet deposition uniformity and chemical liquid deposition in the upper part of crops was the best,and the middle layer was the worst.Centrifugal nozzles have better penetration.
