摘要
近年来,黑龙江省玉米种植面积持续增加,玉米田杂草的防除成为农业生产中最重要的环节,防除效果差会严重影响玉米产量。本实验采用几种除草剂对玉米田进行处理,结果表明,硝基磺草酮对稗草的防效比烟嘧磺隆好,可达到100%,而肇东地区玉米田的稗草比民主实验田的稗草对烟嘧磺隆的耐药性高,烟嘧磺隆对其防效只达到68.08%,而且烟嘧磺隆对苘麻的防效不如硝基磺草酮和氯氟吡氧乙酸。硝基磺草酮和莠去津复配对杂草的总防效最好,可达到99.41%,为玉米田杂草的合理防除提供理论依据。
In recent years, corn planting area in Heilongjiang Province is continuously increasing, the weedcontrol in corn field become the most important link in agricultural production. If the control effect is poor, themaize yield will be seriously affected. In this experiment, several kinds of herbicides were used to deal with theweeds in corn field. The results showed that the control effect of Mesotrione to barnyard grass was better than Nico-sulfuron, and it could be up to 100%. The resistance of barnyard grass to Nicosulfuron in Zhaodong corn field washigher than that in Minzhu field. The control effect of Nicosulfuron was only 68.08%, and the control effect of Nico-sulfuron to abutilon theophrasti medic was worse than Mesotrione and Fluroxypyr. The total control effect of Mesotri-one mixed with Atrazine on weed was the best, it could be up to 99.41%. This can provide theoretical basis for thereasonable control of weeds in corn field.
