| 为探究使用植保无人飞机对井冈蜜柚果树冠层雾滴沉积分布的影响，本文以DJI-T50植保无人飞机为施药试验的载体，在选用不同的飞行速度、相对冠层高度、雾滴粒径和助剂类型下，通过比较各组试验的雾滴沉积分布情况，对不同作业参数组合进行了优选。然后，基于得到的较优参数组合对比了3种不同航线的作业方式。最后，根据筛选最优作业方式及作业参数组合对井冈蜜柚果树进行了柑橘全爪螨Panonychus citri飞防试验，探究了在4种不同药剂作业下井冈蜜柚柑橘全爪螨虫口的减退情况。结果表明：当设置飞行相对冠层高度为3 m、飞行速度为3 m/s、雾滴粒径为210 μm、助剂选用为植健、作业方式为定点旋转作业时，植保无人飞机雾滴沉积效果较好；在柑橘全爪螨防治效果方面，选用阿维·乙螨唑悬浮剂效果较佳，于施药后第7天可达到88.34%；乙唑螨腈悬浮剂起效较快，而虱螨脲水乳剂前期会造成柑橘全爪螨数量激增，然后缓慢下降。本文结论可为井冈蜜柚飞防作业提供数据支持，并为提高井冈蜜柚柑橘全爪螨防治效果提供理论依据。 |

| In order to investigate the effect of using plant protection unmanned aircraft on the canopy droplet deposition distribution of Jinggang honeydew fruit trees, this paper used DJI-T50 as the carrier for the application test, and different combinations of operational parameters were optimized by comparing the droplet deposition distribution of each group of tests under the selection of different flight speeds, relative canopy heights, droplet particle sizes, and additive types. Then, three different flight paths were compared based on the optimal parameter combinations obtained. Finally, based on the screening of the optimal operation mode and operation parameter combinations, a Panonychus citri fly control test was carried out on the fruit trees of Jinggang honeydew, and the reduction of P. citri mite infestation under the operation of four different agents was investigated. The results showed that when the relative canopy height was 3 m, the flight speed was 3 m/s, the droplet size was 210 μm, the additive was Plant Health, and the operation mode was fixed-point rotary operation, the effect of droplet deposition by plant protection unmanned aerial vehicles (UAVs) was better; in the control of P. citri mites, the effect of avibenzoxazole suspension was better, and it could reach 88.34% on the 7th day after the application of the drug, while the effect of acetazolamide suspension was faster. The water emulsion of lufenuron caused a surge of P. citri mite population in the early stage, and then decreased slowly. The conclusions of this paper can provide data support for the fly-control operation of Jinggang honeydew, and provide theoretical basis for improving the control effect of P. citri in Jinggang honeydew. |
