| 摘 要： | 通过田间试验研究28%丁草胺·吡嘧磺隆WP对水稻移栽田杂草的控制效果和对水稻产量的影响。结果表明,28%丁草胺·吡嘧磺隆WP 226.8～525.0 g(a.i)/hm2对水稻移栽田的稗草、鸭舌草、节节草、异型莎草均具有良好的防治效果,综合密度防效和综合鲜重防效优于对照药剂60%丁草胺EC和10%吡嘧磺隆WP;并能有效降低杂草对田间氮、磷、钾和水分的吸收,增产效果明显。

| Abstract: | To provide guidance for chemical weed management in broadcasted rice fields,trials were conducted to evaluate the effects on weed control and crop yield of a fertilizer formulation mixed with 28% butachlor and pyrazosulfuron WP.The results showed that 28% butachlor and pyrazosulfuron WP 226.8~525.0 g(a.i)/hm2 had good control effects on Echinochloa crusgalli(L.) Beauv,Monochoria vaginalis(Burm.F.),Rotala indica,Cyperus difformis L.in transplanted rice fields.The overall fresh control effects and density control effects were significantly higher than 60% butachlor EC and 10% pyrazosulfuron WP.The application of 28% butachlor + pyrazosulfuron WP significantly reduced the weeds absorption of nutrition and water,resulting in prominent yield enhancing. |
