河北沧州地区历年来玉米小地老虎为害非常猖獗,轻则缺苗断垅,重则毁田重种,给玉米高产高收带来挑战。由于地老虎昼伏夜出,地下为害的生活习性,常规喷雾方法防效较差,全田毒土撒施又不符合国家农药减量方针的长期发展。农业部去年正式启动2020年农药零增长行动,提出在不影响国家粮食安全的前提下,农药化肥用量实现零增长,而种子包衣投药定向精准,将会成为农药应用的主推方向之一。
Cangzhou, Hebei over the years over the years to kill the small Tigers are very rampant, ranging from the lack of seedlings cut off, while heavy destruction of fields heavy, high yield corn to bring challenges.
