直播稻田用不同药剂在播种前播种后各一次化除或播种后两次化除都具有很好的除草效果。播后前期是化学除草的关键时期。播后前期每６６７米２用１０％苄嘧黄隆１５克＋６０％丁草胺６０毫升、１０％苄嘧黄隆１５克＋５０％杀草丹１５０毫升、１７２％新幼禾葆（苄嘧黄隆＋丁草胺）２４０克或１５８％幼禾葆２００克（苄嘧黄隆＋哌草丹）防效均较好。播种后第二次化除以３５％丁苄１２０克在播种后１５～２０天使用为宜
Direct-seeded rice fields with different agents before sowing after sowing or sowing twice in addition to all have a good herbicidal effect. Early sowing is a critical period of chemical weeding. After sowing pre-broadcast every 667 m 2 with 10% bensulfuron-methyl 15 g + 60% butachlor 60 ml, 10% bensulfuron-methyl 15 g + 50% dilute herbicide 150 ml, 17 2% Methylthiazolyl + Butachlor) 240 g or 15 8% Young Bao Bao 200 g (bensilanfume + podacarb) control effect is better. After sowing the second time divided by 35% of n-butyl 120 grams 15 to 20 days after sowing is appropriate
