国内外田间机械除草技术研究现状

Review of Mechanical Weeding Technique in Field at Home and Abroad

农田草害一直是阻碍农业生产快速、持续发展的一个重要因素。虽然我国农田杂草综合治理已经取得了长足进步,但杂草危害、演替、抗药性、除草剂药害等问题仍相当严重。为此,从除草作业的缺陷出发,分析了当今国内外田间除草技术的研究现状以及化学除草技术与机、电、光等技术的结合情况;通过与美国、德国等西方发达国家先进除草技术的比较,分析了我国除草技术的不足之处,并指出了除草技术的发展趋势。

Weed pest is a hazard that hinders the fast and sustainable development of agriculture. Although we have achieved great progress in the general control of the weed, there are also some serious problems in the harms of the weed, succession, drug-fast and the pollution of the herbicide. From the limitation of the traditional weed control, the paper analyzed the present status of mechanical weeding technique in field at home and abroad and the combination of the chemical weed control technique with machine, electivity and ray etc. It also pointed out the deficiency of the weed control of our country compared with the advanced technique in the aspect in American and Germany. At last, the development tendency of the weed technique is brought forward.
