近年来,随着冬作大小麦田化学除草面积的日益扩大,大小麦种、芽、苗叶的除草剂药害时有发生。这除了与气候、土壤条件有关外,还与麦类对除草剂的敏感性程度有关。为了有利于今后推广应用化学除草,我们于1986～1987年在衢州市病虫测报站开展了麦种、芽和麦苗对几种常用除草剂的敏感性的试验测定。现将结果汇总如下。 In recent years, with the winter crop size of wheat growing chemical weeding area is growing, the size of wheat, shoots, leaves of the herbicide phytotoxicity have occurred. This is not only related to climate and soil conditions, but also the sensitivity of wheat to herbicides. In order to promote the application of chemical weeding in the future, we conducted the test of the sensitivity of several wheat germs, shoots and wheat germ to several common herbicides in Quzhou Pest and Disease Report Station from 1986 to 1987. The results are summarized below.
