摘  要:
为了明确11%三氟啶磺隆钠盐可分散油悬浮剂(OD)在百慕大草坪上的应用技术,2021年采用田间小区试验测定了三氟啶磺隆钠盐对百慕大草坪杂草的防除效果及其对交播黑麦草生长的影响。结果表明,11%三氟啶磺隆钠盐OD对马唐、空心莲子草、凹头苋、香附子和碎米莎草等杂草均有较好的防效,且对百慕大草坪安全。11%三氟啶磺隆钠盐OD于杂草3~5叶期施用,防除百慕大草坪杂草的适宜剂量为24.75~41.25 g a.i./hm~2,即制剂量为15~25 mL/667 m~2。11%三氟啶磺隆钠盐OD在百慕大草坪使用,交播黑麦草的安全间隔期为60 d。本研究结果可为百慕大草坪杂草治理及安全交播黑麦草提供参考。

摘  要:
In order to determine application technology of trifloxysulfuron sodium 11% OD in bermuda lawns,field experiments were conducted in 2021 to evaluate effect of this herbicide on weeds control and the growth of overseeding Lolium perenne.The results showed that trifloxysulfuron sodium 11% OD had an excellent control effect on weeds such as Digitaria sanguinalis,Alternanthera philoxeroides,Amaranthus blitum,Cyperus rotundus,C.iria and so on,which was selectivity to the growth of bermuda lawns.The appropriate dose of trifloxysulfuron sodium 11 % OD to control weeds in3~5 leaves stage in bermuda lawns was 24.75~41.25 g a.i./hm~2(commercial dose was 15~25 mL/667 m~2).The selectivity interval of trifloxysulfuron sodium 11% OD was 60 days to overseeding L.perenne in bermuda lawns.The finding study could provide a guidance for weed management and selective overseeding L.perenne in bermudagrass lawns.
