[目的]研究不同植物种植模式下根系效应在重金属修复中的效果,为矿山修复奠定理论基础.[方法]构建了基于改良剂的铅锌矿植物修复中试系统,设计CK组(纯矿渣对照)、S0 组(改良矿渣对照),比较单一植物系统S栾(单一乔木栾树)、S夹(单一灌木夹竹桃)、S香(单一草本香根草)、S复(乔灌草复合)的铅锌矿修复效果.[结果]1)试验后,植物组与原矿渣对照组相比pH值提高了 0.14～0.27,含水率、孔隙度、有机质、阳离子交换量分别提高了 5.3%～9.8%、9.6%～11.8%、102.5%～106.9%、54.2%～66.6%;蔗糖酶、脲酶活性分别提升了 130.9%～680.2%、2.4%～8.6%;总氮、总磷、总钾含量分别提升了 85.5%～115.6%、0.0%～22.5...

[Objective]The effect of root effect under different plant planting modes in heavy metal remediation was studied,which laid a theoretical foundation for mine remediation.[Method]An observer-based phytoremediation pilot system of lead-zinc ore was constructed,and the CK group(pure slag control)and S0 group(modified slag control)were designed to compare the lead-zinc ore restoration effects of single plant system SLuan(a single tree koelreuteria),SJia(a single shrub oleander),SXiang(a single herb vetiver),and SFu(compound of trees,shrubs and herb...
