摘　　要：有机硅表面活性剂可以诱导草甘膦快速地通过气孔被植物吸收。气孔吸收的程度与表面活性剂的浓度以及植物的种类有关。常规表面活性剂可以显著影响草甘膦的角质层吸收，角质层吸收的快慢与表面活性剂的化学结构、ＥＯ含量。Organosilicone surfactants are able to induce fast uptake of glyphosate into plant foliage through stomata.The level of stomatal uptake depends on surfactant concentration and plant species.Conventional surfacrants could enhance significantly the cuticular uptake of glyphosate.Their effect,however,varies with chemical structures,EO content and concentration of surfactants as well as plant species.
