在对已有土壤粘附机理进行综合分析的基础上，从结构化学和量子力学的统计效应出发，对参与粘附的各种因素———土壤表面性质、触土部件表面特性、土壤水中各种离子的性质进行了全面分析，从化学吸附角度，提出了以化学吸附为主的土壤粘附机理。该模型认为土壤与触土部件金属材料表面的粘附力是由土壤与金属表面间的化学吸附力（包括物理吸附力）、土壤水在金属与土壤之间形成的化学吸附力（宏观上表现为毛细管力）和水的粘滞阻力三部分组成
Based on the comprehensive analysis of the existing soil adhesion mechanism, based on the statistical effects of structural chemistry and quantum mechanics, various factors involved in the adhesion - the surface properties of the soil, the surface characteristics of the clay components, The properties of ions were analyzed comprehensively. From the perspective of chemical adsorption, the mechanism of soil adhesion based on chemisorption was proposed. The model suggests that the adhesion of soil to the surface of metal parts of the clay component is due to the chemical adsorption between the soil and the metal surface (including the physical adsorption force) and the chemical adsorption force of soil water between the metal and the soil (macroscopically For the capillary force) and the viscous resistance of water in three parts
