摘　　要：鉴于水直播稻田杂草种类多、发生量大、防治技术要求高的现状,为探索适宜铜陵市普济圩农场水直播稻田杂草防除的有效药剂,开展了38%噁草酮悬浮剂与30%丙草胺乳油对水直播稻田杂草的防除效果以及安全性的比较试验。结果表明,施用38%噁草酮悬浮剂0.9L/hm2封闭除草,杂草防效优于常规药剂30%丙草胺乳油1.5L/hm2,总草株防效及鲜重防效均在92%以上,且对水稻安全,适于在水直播稻田推广应用。As present situation,there are various weeds with high infestation LeveL and high technicaL requirements for weed controL in water direct seeding paddy fieLds.According to LocaL herbicide usages and ideaLs of activeLy expLoring new herbicides and technoLogies for weed controL in direct seeding paddy fieLds,a comparative experiment was conducted on weed controL efficacy and safety of 38% Oxadiazon SC and 30% PretiLachor EC to search for suitabLe and effective herbicide in LocaL water direct seeding paddy fieLds.Our resuLts indicated that the controL effects of totaL weed pLant and fresh weight were above 92% by 38% Oxadiazon SC 0.9 L per hectare which was better than PretiLachor EC 1.5L per mu and safe to rice and suitabLe for appLication in direct seeding paddy fieLd.
