农用植保无人机在水稻主要病虫害防治中的应用

Application of Agricultural Plant Protection Drones in the Prevention and Control of Main Rice Diseases and Insect Pests

为探索农用植保无人机在农作物主要病虫害防治中的作用,昆山市积极引进植保无人机开展水稻主要病虫害防治的试验示范。试验结果表明,植保无人机对稻纵卷叶螟的防效达到98.67%;对稻飞虱、纹枯病的最终防效分别为83.57%、89.78%,低于常规植保机的96.43%、98.07%;对水稻大螟的防效仅为48.16%,与常规植保机的73.9%差距较大。农药植保无人机省工节本、防效好、用量少、农药利用率高,但对操控者技术要求高、机身价格高、专业维修点少等。建议由植保专业化服务组织进行采购,培养专业操控人员,提升社会化服务能力,进一步推进全市农作物病虫害统防统治工作。

In order to explore the role of agricultural plant protection UAV in the prevention and control of major crop diseases and pests, Kunshan City has actively introduced plant protection UAV to carry out experimental demonstration of the prevention and control of major rice diseases and pests. The results showed that the control effect of plant protection UAV on rice leaf roller was 98.67%. The final control effects on rice planthpper and sheath blight were 83.57% and 89.78% respectively, which were lower than 96.43% and 98.07% of conventional plant protection machine. The control effect on rice stem borer is only 48.16%, which is far from 73.9% of the conventional plant protection machine. Pesticide plant protection UAV saves labor and cost, has good control effect, low dosage and high pesticide utilization rate, but it has high technical requirements for operators, high fuselage price and few professional maintenance points. It is suggested that the plant protection professional service organization should purchase, train professional operators, improve the socialized service ability, and further promote the unified prevention and control of crop diseases and pests in Kunshan.
