| 摘 要： | 通过田间试验研究10％乙草胺·苄嘧磺隆WP对水稻抛秧田杂草的控制效果和对水稻产量的影响,为水稻抛秧田草害的化学防控提供依据.试验结果表明,10％乙草胺·苄嘧磺隆WP对水稻抛秧田的稗草Echinochloa crusgalli (L.) Beauv]、鸭舌草Monochoria vaginalis (Burm.F.)]、异型莎草(Cyperus difformis L.)均有良好的防治效果,用量为60～120 g(a.i)/hm2的10％乙草胺·苄嘧磺隆WP对杂草的综合鲜重防效和综合密度防效分别为86.64％～99.08％、89.88％～99.44％,优于对照药剂50％乙草胺EC和10％苄嘧磺隆WP.10％乙草胺·苄嘧磺隆WP增产效果优于对照药剂,在水稻抛秧田具有良好的推广前景. |

| Abstract: | To provide guidance for chemical weed management in seedling-throwing transplanted rice fields,trials were conducted to evaluate the effects on weed control and crop yield of a fertilizer formulation mixed with acetochlor and bensulfuron-methyl.The results showed that 10% acetochlor and bensulfuron-methyl WP had good control effects on Echinochloa crusgalli(L.) Beauv,Monochoria vaginalis(Burm.F.),Cyperus difformis L.in seedling-throwing transplanted rice fields.The overall fresh control effects and density control effects are 86.64%～99.08% and 89.88%～99.44% at 60～120 g(a.i)/hm2,and significantly higher than 50% acetochlor EC and 10% bensulfuron-methyl WP.The application of 10% acetochlor and bensulfuron-methyl WP significantly increased the yield of rice which was better than those control herbicides.It has good application prospects in seedling-throwing transplanted rice fields. |
