摘　　要：探讨除草剂添加增效剂减量施用对红枣-小麦间作麦田阔叶杂草的防除效果及安全性,为麦田除草剂减量施用提供科学依据。结果表明,药后50 d,10%苯磺隆WP、20%双氟·氟氯酯WG和6%双氟·唑草酮OD添加增效剂激健在减施20.00%~40.00%的剂量下对麦田阔叶杂草的株防效和鲜质量防效分别为86.83%~98.47%和98.96%~99.87%,分别高于与之相对应的不添加增效剂激健的处理,较空白对照增产8.03%~10.69%,纯增收益为725.80~1099.00元/hm 2,表明10%苯磺隆WP、20%双氟·氟氯酯WG和6%双氟·唑草酮OD添加增效剂激健可在红枣-小麦间作麦田减量施用。To explore the control effect and safety of herbicide by adding synergist on broad-leaved weeds in jujube-wheat intercropping field,an experiment was condeucted to provide scientific basis for reducing herbicide application in wheat field.The results showed that 50 days after the treatment and under the condition of the 20.00%-40.00%of dosage reduction,the control effects of 10%tribenuron-methyl WP,10%halauxifen-methyl+10%florasulam WG and 2%florasulam+4%carfentrazone-ethyl OD added synergist Jijian on broad-leaved weeds were 86.83%-98.47%and 98.96%-99.87%,respectively,which were higher than the corresponding treatments without the synergist Jijian.Compared with the blank control,the yield increased by 8.03%-10.69%,the net benefits increased about 725.80 yuan per hm 2 to 1099.00 yuan per hm 2,The results indicated that 10%tribenuron-methyl WP,10%halauxifen-methyl+10%florasulam WG and 2%florasulam+4%carfentrazone-ethyl OD added synergist Jijian could be recuded to apply in the jujube-wheat intercropping field.
