摘要
为了探索环境材料对重金属污染土壤的植物生长和土壤修复效果,通过盆栽模拟试验研究了单一高分子吸水材料(PAM)、煤基营养物质(CBN)、吸附性矿物材料(MAM)、矿物化学材料(MCM)及各材料不同组合对重金属铅(Pb)、镉(Cd)污染土壤中玉米生长和玉米中重金属累积的影响。结果表明:单一CBN、MAM、MCM及这3种环境材料的组合促进重金属Pb、Cd污染土壤中玉米株高、叶面积的增加和生物量的积累。MAM和MCM抑制重金属Pb、Cd向玉米秸秆和籽粒中转移,CBN抑制重金属Pb向玉米秸秆和籽粒中转移。
In order to explore the effects of environmental materials on plant growth and remedi- ation of heavy metal Pb and Cd contaminated soil, the maize growth and heavy metal accumula- tion in maize under environmental materials polymer absorbent material (PAM), coal-based nutrient (CBN), mineral adsorption materials (MAM), mineral chemical materials (MCM) and their combinations were detected by pot experiment. The results showed that CBN, MAM, MCM and their combination promoted maize height, leaf area and biomass. MAM and MCM restrained the transfer of both Pb and Cd to maize straw and grain, and CBN only re- strained the Pb adsorption of maize plant.
