土壤中的粘土矿物和腐植酸是对农药吸附的最主要两类活性组份。作者从基于红外光谱（ＩＲ）、电子自旋共振谱（ＥＳＲ）、Ｘ衍射等近代分析技术，对农药在土壤活性组份上吸附机理的研究方法和主要结论进行了综述。
Clay minerals and humic acid in soil are the two main types of active components for pesticide adsorption. Based on the recent analysis techniques such as infrared spectroscopy (IR), electron spin resonance spectroscopy (ESR) and X-ray diffraction, the authors summarize the research methods and main conclusions of the adsorption mechanism of pesticides on soil active components.
