8月2日，在宁夏垦区灵武农场，无人机在对水稻喷洒农药。当日，宁夏垦区灵武农场使用小型无人机对200余亩水稻进行了农药喷洒作业实验。据了解，宁夏垦区为解决高秆农作物在生长后期人工喷洒农药难度大、耗时长、成本高等问题，将首次引进飞机航化作业，以确保农作物的增产增收。但受垦区种植面积小而分散的影响，不宜采用大型飞机进行航化作业。此次作业实验采用的小型无人机每小时可对200亩农田完成农药喷洒作业，具有成本低、操作简单、农药喷洒覆盖好等优势。新华社记者 李然 摄 August 2，In ningxia reclamation area LingWu farm，Uavs to spray pesticides in rice。On that day，Ningxia reclamation area LingWu farm use small uavs of more than 200 mu of rice spray pesticides homework experiment。According to understand，Ningxia reclamation area to solve high crop at later growth stage in stem artificial spray is difficult、Are time consuming、Cost is too high，For the first time to introduce the plane of navigation homework，To ensure that crops yield of income。But the planting area of land reclamation area small and scattered influence，Not be used on the large aircraft navigation homework。The operation of the experiment used small uavs can be 200 mu per hour to finish spray pesticides farmland homework，With lower cost、Simple operation、Spray pesticide cover good and other advantages。The xinhua news agency LiRan perturbation
