摘  要:
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45~105g·hm-2(有效成分)兑水675L·hm-2,药后30d防治效果达均可80.00%以上,无药害产生,对水稻安全。

摘  要:
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 Echinochloa crusgalli(L.)Beauv.,Leptochloa chinensis(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 30d-treatment.The recommended concentrations of the herbicide ranged from45g·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.
