In general, sunflower was suited to phytoremediation of moderately Pb-contaminated soil by phytoextraction.The result mentioned above showed that the main reasons that nutrient and EDTA could impact on phytoremediation efficiency was these as below: firstly, the addition of soil amendments transform soil Pb from nonresidual fractions to residual fraction substantially. Secondly, the grown period of tissues in C4 plants was short, so the replacement of C4 plants with C3 plants may increase times and efficiency of remediation.

根据上述结果，不同营养水平和EDTA对铅污染土壤植物修复的机理及效率可以归纳为：N、P、K的添加能使土壤中的非残留态Pb向残留态转化，因此N、P、K的添加能够增加菠菜和苣荬菜体内的铅积累；与C3型植物菠菜、苣荬菜相比，C4型的植物马齿苋由于构件成熟期短，较为适合作短期内铅污染土壤修复工程；在植物修复过程中，低浓度EDTA的分次添加能够显著提高修复的效率，并且能够减小螯合剂增加产生的二次污染。
