摘要: 采用田间试验研究了26%甲基二磺隆·双氟磺草胺·氯氟吡氧乙酸异辛酯可分散油悬浮剂防除小麦田主要杂草的效果,及杂草防除后对氮、磷、钾及水分的影响。结果表明,施用26%甲基二磺隆·双氟磺草胺·氯氟吡氧乙酸异辛酯可分散油悬浮剂防除小麦田杂草效果显著,对牛繁缕[Malachium aquaticum (L.)Fries]、猪殃殃(Galium aparine L.)、大巢菜(Vicia sativa L.)、菵草(Beckmannia syzigachne)等杂草均有良好防效,总鲜重防效达到91.5%~97.3%,显著优于3种对照药剂。杂草防除后,显著降低了杂草对田间氮、磷、钾和水分的消耗,有效改善了田间的水肥条件。26%甲基二磺隆·双氟磺草胺·氯氟吡氧乙酸异辛酯可分散油悬浮剂处理的小麦田产量达3 456.27~3 591.27 kg/hm2,增产效果显著,较清水对照增加36.0%~41.2%,每公顷增收2 101.65~2 412.15元。

Abstract: The effect of 26% mesosulfuron-methyl·florasulam· fluroxypyr-meptyl oil dispersion(OD) on weed control in wheat field was studied. The wheat yield, the content of N-P-K and water were also analyzed after weed control. The results indicated that the efficacy of weed control was remarkable by 26% mesosulfuron-methyl·florasulam· fluroxypyr-meptyl OD in wheat field. The control efficacy of compound formulation on Malachium aquaticum, Galium aparine, Vicia sativa and Beckmannia syzigachne was ranged from 91.5% to 97.3%, which was significantly higher than three individual herbicides. The accumulation of weed water and nutrients was significantly decreased after weed control. The wheat yield was 3 456.27 to 3 591.27 kg/hm2 after treated with 26% mesosulfuron-methyl·florasulam· fluroxypyr-meptyl OD, which increased by 36.0%~41.2% compared to untreated control. Moreover, the yield income increased by 2 101.65~2 412.15 Yuan/hm2.

Key words: mesosulfuron-methyl·florasulam· fluroxypyr-meptyl;, weed control effect, nutrient content, wheat yield
