土壤主要理化性质对湘粤污染农田镉稳定效果的影响
|
摘要
利用盆栽试验研究了稳定剂(石灰、海泡石联合施用)对湖南、广东两省区不同性质土壤上生长的小青菜(Brassica chinensis L.)生物量、重金属吸收以及土壤pH和重金属提取态含量的影响,探讨了影响镉(Cd)稳定修复效果的土壤性质参数。结果表明:施加稳定剂对增加酸性土壤上小青菜生物量效果显著,土壤pH、有机质(OM)、全量Cd和黏粒是影响小青菜生物量变化的主要因素;土壤pH、阳离子交换量(CEC)、OM、黏粒是影响小青菜Cd含量变化的主要因素;土壤pH、CEC、全量Cd和黏粒是影响土壤提取态Cd含量变化的主要因素。
In this study, a pot experiment was conducted and pH value and CaCl2 extractable cadmium(Cd) were determined to investigate the effects of combined amendments(lime and sepiolite) on the plant dry biomass and Cd accumulation of Brassica chinensis L. The results showed that the remediation effects in acid soils were greater than those in calcareous soils.Correlation analysis showed that soil pH, organic matter(OM) contents, clay contents and total Cd were the key factors affecting the biomass of B. chinensis. Soil pH, CEC, OM and clay contents were the key factors affecting Cd concentration in B. chinensis.Soil pH, CEC, total Cd and clay contents were the key factors controlling soil extractable Cd concentrations.
