摘　　要：通过主流防除稗草化学药剂五氟磺草胺、噁唑酰草胺、氰氟草酯、双草醚、二氯喹啉酸等单剂、复配剂及桶混组合10个药剂处理开展田间试验,药后30 d结果表明,在直播早稻中,10%噁唑·氰氟EC 240、300、360、450 g/hm^(2)株防效和鲜重防效均能达94%以上;10%氰氟草酯EC 600 g/hm^(2)、50%二氯喹啉酸WP 450 g/hm^(2)、10%双草醚SC 60 g/hm^(2)鲜重防效分别为81.06%、28.32%、54.56%;25 g/L五氟磺草胺OD 37.5 g/hm^(2)防效最低,株防效和鲜重防效分别为2.34%、7.64%,桶混二氯喹啉酸、双草醚鲜重防效提高至81.85%、67.30%。推荐早稲田以抗性稗草为优势杂草种群,在水稻3叶1心,稗草2叶1心至4叶1心使用10%噁唑·氰氟EC 240~300 g/hm^(2)防效优异,且对水稻安全。The field experiment was carried out on 10 main chemical agents such as penflusulam,metamifop,cyhalofop-butyl,bispyrifos and quinclorac.The results of 30 days after the treatment showed that in direct seeding early rice,the control effect and fresh weight of 10%metamifop·cyhalofop-butyl EC 240,300,360,450 g/hm^(2)were all over 94%.The fresh weight control effects of 10%cyhalofop-butyl EC 600 g/hm^(2),50%quinclorac WP450 g/hm^(2)and 10%bispyrifos SC 60 g/hm^(2)were 81.06%,28.32%and 54.56%respectively;25 g/L pentaflusulam OD 37.5 g/hm^(2)had the lowest control effect,the plant control effect and the fresh weight control effect were 2.34%and 7.64%respectively,the fresh weight control effect of the barrel mixed with quinclorac and bispyrifos was improved to 81.85%and 67.30%.It was recommended that resistant barnyard grass was used as the dominant weed population in the early rice field,and the control effect was excellent when using 10%metamifop·cyhalofop-butyl EC 240-300 g/hm^(2)in three leaves and one heart of rice and one heart of barnyard grass and one heart to four leaves and safe for rice.
