对土壤性质和吸附间关系的研究认为:粘粒和有机质含量是土壤中两个最主要的因子。一般认为,土壤以水为介质对非离子有机物的吸附主要取决于土壤有机质含量,而不是土壤矿质部分。然而,通过对大量不同结构的土壤吸附杀虫剂的研究并经统计处理表 Studies on the relationship between soil properties and sorption show that clay and organic matter contents are the two most important factors in soils. Generally believed that soil water as a medium for non-ionic organic adsorption mainly depends on soil organic matter content, rather than the mineral part of the soil. However, through the study of a large number of different structures of soil adsorbed pesticides and the statistical processing of the table
