近几年来,随着除草剂的推广应用,除草剂药害发生频繁,在生产中造成了巨大的损失,严重影响着农作物的产量和品质,已经成为阻碍杂草化学防治的重要因素。在除草剂大面积使用中,作物产生药害的原因多种多样,只有认识药害、把握药害,才能避免药害、解除药害,实现真正意义上的除草剂科学应用。 In recent years, with the popularization and application of herbicides, the occurrence of herbicide phytotoxicity is frequent, resulting in huge losses in production and seriously affecting the yield and quality of crops, which has become an important factor impeding the chemical control of weeds. In large-scale use of herbicides, crops produce a variety of reasons for phytotoxicity, and only know the phytotoxicity, grasp the phytotoxicity in order to avoid phytotoxicity, remove phytotoxicity, to achieve the true sense of the scientific application of herbicides.
