摘　　要：[目的]明确200 g/L草铵膦AS、41%草甘膦异丙铵盐AS和43%草甘膦钾盐AS定向喷雾对甘薯田行间杂草的防除效果,寻求百草枯替代除草剂。[方法]定向茎叶喷雾,测定不同除草剂对甘薯田行间杂草的防治效果及对甘薯的安全性。[结果]综合15、30、80 d调查结果,各处理对甘薯田行间杂草的平均株防效和鲜质量防效均达85%以上;比空白对照增产13.89%~46.17%,比200 g/L百草枯AS增产1.10%~29.76%。[结论]各供试除草剂能够替代百草枯用于防除甘薯田行间杂草,防治效果好且对甘薯安全。[Aims] The study aims to research herbicides for substitution ofparaquat 200 g/L AS, the control effect of glufosinate 200 g/L AS, glyphosate isopropylamine salt 41% AS and glyphosate potassium salt 43% AS was conducted for controlling inter-row weeds in sweet potato fields. [Methods] The control efficacy of different herbicides against weeds in sweet potato field and their safety to sweet potato were evaluated by filed foliage spray test. [Results] The control efficacy of the tested herbicides was above 85% on 15, 30 and 80 d after treatment. Their yields increased by 13.89 to 46.17% compared to blank controls and increased by 1.10 to 29.76% compared to paraquat 200 g/L AS. [Conclusions] The tested herbicides can substitute paraquat for controlling inter-row weeds in sweet potato fields and are safe to sweet potato production. They can significantly increase the sweet potato yields.
