[目的]为有效的控制玉米田各种杂草,减少大量施药而产生的药害,找出高效安全的除草浓度,[方法]对玉米田杂草(马唐、马齿苋、反枝苋)进行田间药效试验。通过对不同浓度15%硝磺草酮可分散油悬浮剂对不同杂草施药后,防治效果进行差异显著性分析。[结果]除人工除草外,15%硝磺草酮可分散油悬浮剂用量为11320 g/hm2,于施药后的3个时期对玉米田马唐、马齿苋、反枝苋的防效均达到最大,且对上述3种杂草的鲜重质量变化的影响也是最大。[结论]15%硝磺草酮对玉米田杂草(马唐、马齿苋、反枝苋)防效较好,可以广泛的推广和应用。

The aim was to effectively control weeds in maize fields and reduce herbicide damages by exploring the optimal concentration of highly-efficient and safe herbicides. [Method] Herbicide effects on weeds, such as Digitaria san-guinalis, Portulaca oleracea and Amaranthus retroflexus, in maize field were tested, and the significance analysis was conducted on prevention effects with 15%mesotrione (oil suspending agent). [Result] Except of manual weeding, the preven-tions on Digitaria sanguinalis, Portulaca oleracea and Amaranthus retroflexus al reached the peaks with 15% mesotrione (oil suspending agent) at 11 320 g/hm2, and fresh weights proved changed the most dramatical y. [Conclusion] It is clear that the prevention effects of 15% mesotrione oil suspending agent are better on Digi-taria sanguinalis, Portulaca oleracea and Amaranthus retroflexus, which should be widely applied and promoted.
