[目的]筛选可防除玉米田刺果藤并兼治其他杂草的除草剂。[方法]试验设9种除草剂处理,通过田间试验,评价各药剂的除草效果。[结果]55%硝磺·莠去津SC 783.75 g a.i./hm2和4%烟嘧磺隆OD 24 g a.i./hm2+38%莠去津SC 570 g a.i./hm2的防效较好,用药较少,药后30 d,2种处理对刺果藤的鲜质量防效均在87%以上,对总杂草的鲜质量防效均在89%以上。[结论]上述2种处理适用于发生刺果藤的玉米田除草。
[Objective] The research aimed to screen the herbicides that can prevent and cure Cornice thorn vine and other weeds. [Method] Nine herbicides were tested in the experiment. The field herbicides were used to evaluate the herbicidal effect of each herbicide. [Result] The control effect of 55% nitrofurantoatrazine SC 783.75 g ai / hm2 and 4% nicosulfuron OD 24 g ai / hm2 + 38% atrazine A 570 mg / hm2 was better than that of the control group After 30 days of treatment, the fresh weight control effects of the two treatments on the thorns and vines were above 87%, and the fresh mass control effect on the total weeds was over 89%. [Conclusion] The above two treatments were suitable for the weed control in the corn field where thorn rattan vine occurred.
