| 摘 要： | 采用田间小区试验方法,研究了17%苄.二甲戊WP对水稻移栽田主要杂草的防除效果,同时测定了其对水稻产量以及杂草氮、磷、钾和水分含量的影响。结果表明,有效成分用量为89.25～255.00 g/hm2的17%苄.二甲戊WP施药后50 d,稗草的密度防效和鲜重防效分别为88.45%～99.44%、91.63%～98.56%,鸭舌草的密度防效和鲜重防效分别为97.64%～100.00%、95.91%～100.00%,异型莎草的密度防效和鲜重防效分别为85.76%～99.03%、86.89%～99.38%;显著优于对照药剂33%二甲戊灵EC和10%苄嘧磺隆WP。施用17%苄.二甲戊WP能降低杂草对田间养分和水分的吸收,从而提高水稻产量。

| Abstract: | By field trials,control effect of 17% bensulfuron methyl + pendimethalin WP against weeds in transplanted rice field was studied.Besides,trials were conducted to evaluate its effects or crop yield and the absorption of nitrogen,phosphorus,kalium and moisture.The results showed that excellent weed control performance was achieved 50 days after 17% bensulfuron methyl + pendimethalin WP was applied.And with the dosage of 89.25~255.00 kg/hm2,the density control effects of Echinochloa crusgalli(L.)
