| 摘 要： | 直播稻田用不同药剂在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％丁划胺６０毫升，１０％苄嘧黄隆１５克＋５０％杀草丹１５０毫升，１７．２％新幼禾葆２４０克或１５．８％幼禾葆２００克防铲均较好。

| Abstract: | The field trails conducted in Jiaxing City,Zhejiang Province showed that effective weed control was achieved by the application of herbicide combinations of bensulfuron methyl with butachlor(22.5g/ha+540g/ha),bensulfuron methyl with thiobencarb (22.5g/ha+1125g/ha),Xingyouhebao (bensulfuron methyl+butachlor)619.2g/ha,and youhebao (bensulfuron methyl+dimepiperate)470g/ha in the early stage after sowing separately.Sometimes, in additional application of Ding bian (butachlor+bensulfuron methyl)630g/ha was needed 15 to 20 days after the rice sowing. Excellent weed control had been obtained by herbicide treatments before or after the rice sowing ,as well as the treatments in two different times after sowing.The early stage after sowing was the crucial period of weed control in the direct-sowing rice field. |
