摘　　要：在研究直播稻田杂草发生特点基础上 ,经进一步试验比较获得杀草谱广、持效期长、除草效果好、对作物安全的杀·苄 (thiobencarb·bensulfuronmethyl)、丙·苄 (pretilachlor·bensulfuronmethyl)、施·苄 (pendimethal in·bensulfuronmethyl)一次化除方案 ,及与之相配套、具针对性的千金 (cyhalofopbutyl)、霸威 (Fenoxaprop p ethyl·quinclorac·bensulfuronmethyl)等中后期补充除草方案 ,并进行了较大面积的示范和推广 ,有效地遏制了直播稻田的杂草危害。On the basis of studying the characteristics of the weeds occurring in direct seeding rice field, an one-time chemical weeding program, by thiobencarb·bensulfuron methyl, pretilachlor·bensulfuron methyl and pendimethalin·bensulfuron methyl which can kill a broad spectrum of weeds, not only have a long effect but also be safe for the crop, was obtained through comparative experiments, and its necessary supplementary program was applied to weeding at the middle and late stage. A rather large-area demonstration and extension of these programs effectively checked the damage by weeds in direct seeding rice field.
