Abstract:

以大豆、黑麦草和南瓜为材料,运用盆栽实验,通过3种植物的单作和间作对多氯联苯污染土壤的根际修复效应进行了研究。结果表明,植物不同种植方式均对根际土壤中PCB浓度的降解有促进作用,其中植物单作的去除率比CK提高了10.4%~17.0%,植物间作的去除率比CK提高18.4%~23.9%。南瓜-大豆体系中的大豆根的蓄积浓度显著差异高于其他处理,而与大豆南瓜间作方式下黑麦草根蓄积浓度均比其单作显著提高,大豆-南瓜和南瓜-黑麦草间作系统中的大豆和黑麦草根中PCB蓄积浓度也显著提高(P<0.05)。各处理间根际土壤的pH、Eh、电导率的差异性规律性不大。相关分析结果表明,根际土壤PCB去除率与植物吸收量呈显著正相关,而与pH、Eh和电导率没有达到显著相关。
