摘    要:【目的】 评价增效剂对春麦田除草剂增效作用,为安全高效应用除草剂及其减量增效提供依据。【方法】 采用随机区组方法,定点取样调查各小区的杂草株数、鲜质量,评价增效剂对双氟·氟氯酯防除春麦田阔叶杂草的增效作用及安全性。【结果】 20%双氟·氟氯酯WG添加增效剂甲基化植物油、乙烯基三乙氧基硅烷或有机硅对春麦田阔叶杂草的株防效和鲜质量防效分别为95.63%~100.00%和96.91%~100.00%,显著高于20%双氟·氟氯酯WG的株防效和鲜质量防效,但添加增效剂各处理株防效和鲜质量防效之间均无显著性差异。添加增效剂各处理增产率为5.33%~6.29%,增加效益为819.44~964.54 元/hm2,但各处理之间无显著性差异。【结论】 生产上可用20%双氟·氟氯酯WG 15.00 g/hm2 +甲基化植物油225.00 g/hm2,或乙烯基三乙氧基硅烷67.50 g/hm2,或有机硅225.00 g/hm2,防除春麦田阔叶杂草。

Abstract:【Objective】 To assess the synergistic effects of synergists on herbicides in spring wheat aiming to provide the basis for the safe and efficient application of herbicides.【Method】 Randomized block design was used to research the number and the fresh weight of weeds at fixed spots, and the synergism and safety of florasulam·halauxifen-methyl in controlling broad-leaved weeds in spring wheat field was evaluated.【Result】 The control effects of 20% florasulam·halauxifen-methyl WG with methylated vegetable oil, vinyltriethoxysilane or organic silicon on broadleaf weeds in spring wheat field were 95.63% - 100.00% and 96.91% - 100.00%, respectively, which were significantly higher than those of 20% florasulam·halauxifen-methyl WG.However, there was no significant difference in the control effect of different treatment added synergist.The yield increased by 5.33% - 6.29% and the benefit increased by 819.44- 964.54 yuan/hm2, but there was no significant difference among the treatments.【Conclusion】 20% florasulam·halauxifen-methyl WG 15.00 g/hm2 + methylated vegetable oil 225.00 g/hm2 or vinyltriethoxysilane 67.50 g/hm2 or organic silicon 225.00 g/hm2 can be used to control broad-leaf weeds in spring wheat field.
