通过5种植物、基质、钝化剂、重金属浓度对4种重金属吸附能力的正交试验研究表明:伞竹对4种重金属(Cu、Hg、Pb、Zn)综合吸收量为5种植物中效果最好,麦冬次之;EDTA对植物重金属吸收量抑制效果最优,4种钝化剂的治理效果依次为:EDTA>石灰>有机肥>硅肥;珍珠岩最有利于植物对重金属的吸收,5种基质对重金属的治理效果依次为:珍珠岩>菌渣>土壤>炉渣>河沙;并且以重金属低浓度污染时植物净化效果较为显著。通径分析表明:植物品种的重金属吸收浓度比植物的生物产量在吸收重金属过程中更重要。
通過5種植物、基質、鈍化劑、重金屬濃度對4種重金屬吸附能力的正交試驗研究錶明:傘竹對4種重金屬(Cu、Hg、Pb、Zn)綜閤吸收量為5種植物中效果最好,麥鼕次之;EDTA對植物重金屬吸收量抑製效果最優,4種鈍化劑的治理效果依次為:EDTA>石灰>有機肥>硅肥;珍珠巖最有利于植物對重金屬的吸收,5種基質對重金屬的治理效果依次為:珍珠巖>菌渣>土壤>爐渣>河沙;併且以重金屬低濃度汙染時植物淨化效果較為顯著。通徑分析錶明:植物品種的重金屬吸收濃度比植物的生物產量在吸收重金屬過程中更重要。

The orthogonal test incIuding heavy metal, matrixes, passivation agents, and five pIants was conducted. The resuIts showed that Cyperus alternifoIius per-formed the best among the 5 kinds of pIants in the comprehensive absorptive amount of the 4 kinds of heavy metals named Cu, Hg, Pb, Zn, the foI owing is Radix ophiopogonis. EDTA showed the best inhibitory effects on the absorptive amounts of heavy metals. The governance effects of the 4 kinds of passivation a-gents were in the order of EDTA > Iime > organic fertiIizer > siIicon fertiIizer. PerIite was the most favorabIe matrix for pIants to absorbing the heavy metals, and the governance effects of the 5 kinds of matrix were in the order of perIite > mushroom dreg > soiI > furnace sIag > river sand. PIants showed the most significant purifica-tion effects on the contaminated soiI when soiI contalns Iow concentration heavy metals. The path analysis showed that pIant varieties pIayed a much more important roIe in heavy metal absorption than that of the pIants biomass.
