摘　　要：通过田间试验研究了0.11%苯噻酰草胺？苄嘧磺隆颗粒剂（药肥混剂）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。结果表明,0.11%苯噻酰草胺？苄嘧磺隆颗粒剂（药肥混剂）对水稻抛秧田的稗草[Echinochloa crusgalli（L.）Beauv]、异型莎草（Cyperus difformis L.）、鸭舌草[Monochoria vaginalis（Burm.F.）]等均具有良好的防治效果,综合防效达97.28%-100.00%,显著优于对照药剂50%苯噻酰草胺WP和10%苄嘧磺隆WP。0.11%苯噻酰草胺？苄嘧磺隆颗粒剂（药肥混剂）施用后,有效改善了田间的光照和水肥条件,增产效果显著。In order to provide reference for chemical weed management in seedling-throwing rice fields, trials were conducted to evaluate the effects of 0.11% mefenacet ＋ bensulfuron-methyI granules （pesticide-fertilizer mixture） on controlling weeds in seeding-throwing rice fields and on yield of rice. The results showed that 0.11% mefenacet ＋ bensulfuron-methyI granules had good control effects on Echinochloa crusgalli（L.）Beauv,Cyperus difformis L.,Monochoria vaginalis （Burm. F.） in seedling-throwing rice fields,with 97.28%-100.00% overall control effects, and significantly higher than 50% acetochlor EC and 10%bensulfuron-methyI WP. The application of 0.11% mefenacet ＋ bensulfuron-methyI granules effectively improved the light and water-fertilizer conditions in fields, with significant yield-increasing effect.
