摘　　要：通过土壤条件培养动力学试验,设计了8个采样时间点(5 d、10 d、15 d、20 d、30 d、40 d、60 d、90 d),探究了表面活性剂类土壤改良剂对土壤理化指标的影响,结果表明:表面活性剂类土壤改良剂在一定程度上能促进土壤大团聚体的形成,能调节土壤酸碱度,增加速效钾、碱解氮的含量,能降低有效态重金属Pb的含量,但有增加有效态Cd的含量的风险。In this study, eight sampling time points(5 d, 10 d, 15 d, 20 d, 30 d, 40 d, 60 d, 90 d) are designed to explore the influence of surfactant soil amendments on soil physical and chemical indexes through soil culture kinetics test. The results show that: to some extent, surfactants can promote the formation of soil large aggregates, regulate soil pH, increase the contents of available potassium and alkali-hydrolyzed nitrogen, reduce the content of available heavy metal Pb, but have the risk of increasing the content of available Cd.
