防治水稻病虫害无人机施药4867公顷
2017-08-25 08:17:07 中国青年网
8月16日清晨,记者在东港市新兴区土房北村陈德奎的水稻田地头看到,3架无人机在绿油油的稻田里来回穿梭喷洒农药。“为了保证药效的发挥,喷洒农药的无人机需在距离地面3米以下,作业时间要选择在早晚两头,1台无人机日喷洒面积在26公顷左右。”丹东市农业技术推广中心主任刘军向记者介绍说,今年丹东市农委向省里积极争取农业生产救灾水稻病虫害疫情补助资金146万元,实施水稻病虫害防治面积4867公顷。按项目要求,一律采用无人机施药。
记者了解到,无人机施药是近年来开始推广的一种新兴病虫害防治技术。相比传统的施药方式,无人机施药效率更高,施药效果更好,施药人员安全性更高,是未来植保发展的新方向。今年也是丹东首次大规模使用无人机防治水稻病虫害。由于施药地块水稻育期早晚不一,预计施药作业将于8月末完成。
