摘  要:
通过田间小区试验验证了47%氯吡·丙·异可湿性粉剂对水稻旱直播田杂草的防效及对水稻的安全性。结果表明:药后15、45 d,47%氯吡·丙·异可湿性粉剂705~1 410 g a.i./hm~2播后苗前喷雾处理后对稗属杂草、千金子、马唐、鳢肠、耳叶水苋、异型莎草、碎米莎草等杂草的株防效和鲜质量防效均达90%以上,水稻的株高和茎蘖数与人工除草处理无显著差异;收获时测产,47%氯吡·丙·异可湿性粉剂705~1 410 g a.i./hm~2播后苗前喷雾处理后,水稻的有效穗数、穗粒数和理论产量与人工除草处理无显著差异。47%氯吡·丙·异可湿性粉剂705~1 410 g a.i./hm~2播后苗前喷雾处理可有效防除水稻旱直播田多种杂草,对水稻安全。

摘  要:
A field experiment was carried out to investigate the efficacy and selectivity of halosulfuron- methyl · pretilachlor· isoproturon 47% WP in dry direct- seeded rice. The herbicide mixture applied at 705 g a. i. / hm~2and846 g a. i. / hm~2 after sowing but before seedling emergence did not negatively affect plant height,tiller number,number of effective panicles,grain number per panicle,and estimated grain yield compared to hand weeding. Both treatments provided above 90% control of Echinochloa spp.,Leptochloa chinensis,Digitaria sanguinalis,Eclipta prostrata,Ammannia arenaria,and Cyperus spp.
