摘 要：
试验研究了30%苄.异丙草胺WP防除水稻移栽田稗草和鸭舌草的效果,并测定了对杂草氮、磷、钾和水分的影响。试验结果表明,30%苄.异丙草胺WP对水稻移栽田的稗草和鸭舌草具有良好的防治效果。有效成分用量90.0～135.0 g/hm2的30%苄.异丙草胺WP施药后50 d,稗草的密度防效和鲜重防效分别为89.31%～94.30%、91.69%～96.02%,鸭舌草的密度防效和鲜重防效分别为96.83%～98.76%、96.76%～97.99%,总体防效优于对照药剂72%异丙草胺EC和10%苄嘧磺隆WP。施用30%苄.异丙草胺WP能降低杂草对田间养分和水分的吸收,提高水稻产量。

摘 要：
Trials were conducted to evaluate the effects of wettable powder mixed with bensulfuron-methyl and propisochlor for control of Echinochloa crusgalli(L.) Beauv and Monochoria vaginalis(Burm.F.),and the absorption of nitrogen,phosphorus,kalium and moisture.The results showed that 30% bensulfuron-methyl + propisochlor WP from 90.0 g/hm2 to 135.0 g/hm2 had good control of the main weeds in transplanted rice fields.50 days after the application,the density control effects and fresh control effects of Echinochloa crusgalli(L.) Beauv were 89.31%～94.30%,91.69～96.02%,and the density control effects and fresh control effects of Monochoria vaginalis(Burm.F.) were 96.83%～98.76%,96.76%～97.99% which were better than 72% propisochlor EC and 10% bensulfuron-methyl WP.The application of 30% bensulfuron-methyl + propisochlor WP significantly reduced the weeds absorption of nutrition and moisture,resulting in prominent yield enhancing.
