目前,在农业生产尤其是粮食种植过程中,从种到收基本实现了机械化,唯独植保环节,多数还是靠人工背着喷雾器打药,是机械化程度最低的一环。最近几年,随着无人机技术的快速发展,其应用领域越来越广,不少地方也开始尝试利用植保无人机进行病虫害的防治。过去,国内农民通过报纸、电视等渠道看到外国农民用飞机打药,高效快捷,羡慕不已。如今,飞机打药似乎离国内农民不再遥远。但笔者认为,应用植保无人机依然存在多个问题,目前还不宜盲目大面积推广,利用植保无人机打药,等等再“飞”也不迟。 At present, in the process of agricultural production, especially grain cultivation, mechanization has basically been implemented from planting to harvesting. In the case of plant protection, most of them still rely on sprayer sprays to fight pesticides by hand, which is the lowest degree of mechanization. In recent years, with the rapid development of UAV technology, its application fields are becoming more and more widely. Many places have also begun to try pest and disease control using plant protection unmanned aerial vehicles. In the past, peasants in the country saw the entertaining of foreign peasants flying their aircraft through newspapers, television and other channels with quickness and efficiency. Today, it seems that aircraft fight drugs are no longer far from domestic peasants. However, I believe that there are still many problems in the application of UAVs. At present, it is not advisable to popularize them blindly and use UPCs to fight drugs, and so on.
