为有效控制福建地区直播稻田禾本科杂草的危害，以莆田市仙游县游洋乡的水稻种植基地为试验点，选择测定1％噁嗪草酮悬浮剂、10％双草醚悬浮剂和20％氰氟草酯油悬浮剂等3种除草剂对稗草、千金子等禾本科杂草的防治效果，筛选确定最佳除草剂及其理想的田间使用浓度。结果表明：20％氰氟草酯油悬浮剂是防治直播稻田中稗草、千金子等禾本科杂草最佳的除草剂，田间推荐使用浓度为45～105 g · hm －2（有效成分）兑水675 L · hm －2，药后30 d防治效果达均可80.00％以上，无药害产生，对水稻安全。

In order to effectively control annual grass weeds of rice fields in Fujian , three herbicides with different concentrations ,including 1% oxaziclomefone suspending agent , 10% bispyribac‐sodium suspension and 20%Cyhalofop‐butyl oil suspension ,were selected to control grass weeds ,such as Echinochloacrusgalli (L .) Beauv ., Leptochloachinensis (Linn .) Nees in Youyang township of Xianyou ,Putian city .The results showed that :20%Cyhalofop‐butyl oil suspension is the best herbicide in direct seeding paddy fields to control grass weeds and the control effect was above 80% after 30 d‐treatment . The recommended concentrations of the herbicide ranged from 45 g · hm -2 to 105 g · hm-2 (active ingredient ) with the water 675 L · hm-2 . Under the recommended concentrations , the herbicide is safe to rice .
