摘　　要：[目的]研究三氟啶磺隆防除细叶结缕草草坪杂草的效果、杀草谱、合理使用剂量及其对草坪的安全性,为大面积生产应用提供科学依据。[方法]采用单因素随机区组试验设计,在细叶结缕草草坪上,用100 g/L三氟啶磺隆OD 300～750 ml/hm2进行茎叶喷雾处理防除杂草研究。[结果]600～750ml/hm2的100 g/L三氟啶磺隆OD能有效防除酢浆草,其防效优于对照药剂25%秀百宫WDG;也能够较好地防除单穗水蜈蚣等莎草科杂草,对马唐也有一定的抑制效果,防效接近对照药剂25%秀百宫WDG;对两耳草、母草、粗叶耳草等防效相对较差;对成坪的细叶结缕草生长无影响,对草坪安全。[结论]在细叶结缕草草坪上使用600～750ml/hm2的100 g/L三氟啶磺隆OD较为适宜。[Objective]The aim was to investigate the weed control effect,control spectrum of weed,reasonable application dose and the security of trifloxysulfuron to Zoysia tenuifolia lawn,so as to provide scientific basis for the application of trifloxysulfuron on lawn.[Method]Weed control study was conducted by taking foliage spray on Zoysia tenuifolia lawn with 100 g/L trifloxysulfuron OD 300-750 ml/hm2 using single factor random block test.[Result]600-750 ml/hm2 100 g/L trifloxysulfuron OD had a good control effect on Oxalis corniculata,which was better than contrast herbicide 25% Shibagen WDG.There was also a good control effect on Cyperaceae such as Kyllinga cororata（L.） Druce,100 g/L trifloxysulfuron OD had a braking effect on Digitaria sanguinalis（L.） Scop,which was similar to contrast herbicide 25% Shibagen WDG;it had a relative poor control effect on Paspslum conjugatum,Lindernia crustacean（L.） F-Muell,Hedyotis hispida and so on.The herbicide was safe to the lawn and had no influence on the growth of Zoysia tenuifolia.[Conclusion]The application of 600-750 ml/hm2 100g/L trifloxysulfuron OD on Zoysia tenuifolia lawn is more appropriate.
