为寻找铅污染土壤净化和景观化的材料,采用盆栽方法,研究了3种花卉对铅污染土壤的修复性能。结果表明,3种花卉中孔雀草(Tagetes patula)地上部吸收富集铅的量最大,积累铅能力最强,其次为大丽花(Dahlia pinnata),羽叶茑萝(Ipomoea quamoclit)吸收积累铅能力最弱。在Pb浓度为1000 mg/kg时,大丽花和孔雀草耐性较强,可用作铅污染土壤的稳定修复植物。

To enrich data of Pb toxicity, purify and beautify Pb-contaminated environment, three ornamental flowers were used to determine the absorbing characteristics of Pb and endurable characteristics with pot-culture experiment. The results showed Tagetes patula had a stronger capability of accumulating Pb in shoot than that Dahlia pinnata and Ipomoea quamoclit, but had the weakest accumulating ability. Dahlia Pinnata Cav and Tagetes patula exhibited stronger endurance to Pb, which could be used for stable remediation of soil.
