| 摘 要： | 用批量平衡法对三唑酮在湘南红壤、内蒙古黑土及北京地区浅色草甸土3种不同土壤的吸附行为进行了研究,测得三唑酮在这3种土壤的吸附均能用Freundlish方程较好地进行描述,吸附性随供试土壤理化性质的差异呈明显变化.三唑酮在土壤固相中的分配主要受土壤有机质、阳离子交换量和pH值的影响,在土壤中的吸附常数Kf与土壤阳离子交换量、pH值呈显著正相关.三唑酮在供试土壤上的吸附是表面吸附-分配作用模式,但以物理吸附为主.

| Abstract: | The adsorptions of triadimefon in different soils were studied by using batch equilibrium method.The isotherm data were fitted to the Freundlish equation,and adsorption of triadimefon varied with the different properties of the soils tested.The Kf valves increased with increasing organic matter,CEC and pH,the correlative coefficient between Kf and pH and CEC were 0.884 and 0.994.Adsorption of triadimefon in soils belongs to surface adsorption-distribution mode,but surface adsorption plays a leading role. |
