[目的]探讨3种除草剂对罗布麻田杂草防除效果。[方法]采用专杀禾本科杂草的盖草能、精喹禾灵乳油和专杀阔叶杂草的白阔净进行了2年生罗布麻田杂草的除草试验。[结果]高效盖草能对禾本科杂草具有较好的防治效果,施药后其对稗草和狗尾草的杀灭效果均在35.0%以上;精喹禾灵对稗草和狗尾草的杀灭效果分别为14.8%和28.6%;白阔净对藜具有较好的杀灭效果,防治效果达到30.8%,且未对罗布麻造成药害。[结论]为完善罗布麻栽培技术提供了理论依据。 [Objective] The research aimed to study the control effects of three kinds of herbicides on weeds in Apocynum. [Method] The weeding experiments of 2-year-old Apocynum weeds were conducted by using Gaillargine, Quizalofop-P-ethyl and Pseudoquimir-based broad-leaved weeds. [Result] Hailing grass could have a good control effect on grass weeds. The killing effect on barnyardgrass and green foxtail was above 35.0% after it was applied. The effect of quizalofop-p-ethyl on the killing of barnyardgrass and foxtail The results were 14.8% and 28.6%, respectively. Baikuojing had better killing effect on quinoa, and the control effect was 30.8%, which did not cause any phytotoxicity to Apocynum venetum. [Conclusion] This provided the theoretical basis for perfecting the cultivation technology of Apocynum.
