[目的]探讨磺酰磺隆对小麦田杂草的除草活性。[方法]采用室内生物测定方法测定了磺酰磺隆对11种麦田杂草的除草活性,并在小麦田进行了田间试验。[结果]温室试验表明:磺酰磺隆对荠菜、菵草和硬草有很好的防除效果,ED50值分别为1.49、0.98、5.33 g a.i./hm2;对猪殃殃、麦家公、麦瓶草也有较好的效果;对野燕麦等有较好的抑制生长作用,但对播娘蒿、节节麦效果较差。田间试验表明:磺酰磺隆对猪殃殃杂草等均有较好的防效且对小麦安全。[结论]磺酰磺隆可以应用于小麦田防除多种杂草。
[Objective] The research aimed to study the herbicidal activity of sulfosulfuron against weeds in wheat field. [Method] The herbicidal activity of sulfosulfuron against 11 kinds of wheat weeds was determined by indoor bioassay and field experiments were conducted in wheat field. [Result] The results of greenhouse experiments showed that sulfosulfuron had good control effects on Shepherd ’s purse, gall grass and hard grass with ED50 values of 1.49, 0.98 and 5.33 g ai / hm2, respectively. Bottle grass also has a good effect on the wild oats and other better inhibition of growth, but sowing Artemisia, nodule wheat less effective. Field experiments showed that: Sulfosulfuron on the weeds such as calamus have a good control effect and wheat safety. [Conclusion] Sulfosulfuron could be used in wheat field to control many weeds.
