| 摘 要： | 研究了吡虫啉在土壤中的吸附及作用。结果表明，吡虫啉在土壤中的吸附主要归结于土壤有机质对它的结合，其它因素影响较小，Ｆｒｅｕｎｄｌｉｃｈ常数Ｋｆ与ＯＭ（％）有较好的相关性；吡虫淋能与腐殖酸作用发生电荷转移，并能与腐殖酸羟基形成氢健。

| Abstract: | The adsorption of imidacloprid in soils was investigated.Adsorption was found to be correlated with organic matter in soil and the Freundlich constant Kf=1.69+1.66×OM](r2=0.993).The results of IR analysis showed the formation of hydrogen bonds and the results of ESR suggested the existence of electricity donor acceptor mechanism between imidacloprid and humicacid. |

| Keywords: | imidacloprid soils humicacid adsorption mechanism |
