| 摘 要： | 试验研究15％乙氧磺隆WG防除水稻直播田鸭舌草Monochoria vaginalis (Burm.F.)]和异型莎草(Cyperus difformis L.)的效果,并测定杂草防除对田间杂草氮、磷、钾、水分吸收及水稻产量的影响.结果表明,15％乙氧磺隆WG 11.25～31.50 g(a.i)/hm2对直播稻田鸭舌草的防效为90.31％～100.00％,对异型莎草的防效为89.24％～100.00％.施用15％乙氧磺隆WG能有效降低杂草对氮、磷、钾和水分的吸收,改善田间的光照和水肥条件,水稻增产效果显著. |

| Abstract: | Trials were conducted to evaluate the effects of 15% ethoxysulfuron WG for control of Monochoria vaginalis(Burm.F.) and Cyperus difformis L.,as well as the absorption of nitrogen,phosphorus,kalium,moisture and crop yield.The results showed that 15% ethoxysulfuron WG at the dose of 11.25～31.5 g/hm2 had good control of the main weeds in direct-seeded rice field.The control effect against M.vaginalis was 90.31%～100.00%,and against C.difformis was 89.24%～100.00%.The application of 15% ethoxysulfuron WG significantly reduced the weeds absorption of nutrient and water,resulting in prominent yield enhancing. |
