摘　　要：针对水稻田杂草群体多、变异快、抗性大和防治难的问题,进行了三唑磺草酮·莎稗磷除草剂对移栽水稻和直播水稻田杂草防除效果的研究。试验表明,无论在移栽水稻田还是直播水稻田中,10%三唑磺草酮·莎稗磷可分散油悬浮剂(OD)有效成分施用量375~600 g·hm^(-2),在移栽水稻或直播水稻返青立苗后,稗草等杂草2~3叶期,喷雾处理,对稻田中的稗草、千金子等禾本科杂草具有较好的防治效果,田间主要杂草的防治效果均在97.4%及以上,稻谷产量增加42.10%及以上,且对水稻生产安全。因此,10%三唑磺草酮·莎稗磷OD可以用来防治水稻田中的稗草和千金子等禾本科杂草。In response to the problems of large populations,rapid variation,high resistance,and difficult control of weeds in rice fields,an experiment was conducted on the weed control effect of tripyrasulfone·anilofos herbicide on transplanted rice and direct seeding rice fields.The experimental results indicate that,whether in transplanting rice fields or direct seeding rice fields,the application amount of 10%tripyrasulfone·anilofos dispersible oil suspension(OD)active ingredient is 375-600 g·hm^(-2)after the transplanted rice or the direct seeded rice returns to green,weeds such as barnyard grass are treated by spraying at 2-3 leaf stages.It has good control effect on weeds such as barnyard grass and millet in rice fields.The control effect of the main weeds in the field is 97.4%or above,and the rice yield increases by 42.10%or above,which is safe for rice production.Therefore,10%tripyrasulfone·anilofos OD can be used to control weeds such as barnyard grass and millet in rice fields.
