近些年来,冬麦田化学除草面积日益扩大,特别是推广免耕麦以后,化学除草得到了迅速发展。冬麦田除草大多在播前、播后苗前和幼苗期施药,由于缺少安全性研究。麦田使用除草剂后时发生药害,不仅苗叶受害较多,而且影响种子发芽成株的问题更为突出。为了有利于推广麦田化学除草,提高对作物安全性的认识,完善麦田化学除草应用技术,我们于1986年11～12月间在浙江省衢州市病虫测报站测定了小麦种芽对10种国内外常用除草剂的敏感性反应,现将结果整理如下:
In recent years, the area of chemical weed control in winter wheat fields has been expanding. Especially after the promotion of no tillage, the chemical weeding has been rapidly developed. Most winter wheat weeding before sowing, sowing seedlings and seedling spraying, due to lack of safety studies. Phytotoxicity occurred after the use of herbicides in the wheat field. Not only the seedling leaves suffered more but also the problems that affected seed germination became more prominent. In order to promote the promotion of wheat field chemical weeding, improve the understanding of crop safety, improve wheat weeding application of chemical technology, we in 1986 from 11 to December in Quzhou City, Zhejiang Province pest forecasting test of wheat germination of 10 kinds of domestic Herbal commonly used outside the sensitivity of the reaction, the results are now organized as follows:
