| 摘 要： | 为寻找铅污染土壤净化和景观化材料，采用盆栽方法，研究3种菊科观赏花卉在铅污染条件下对铅的富集特征。结果表明3种花卉中观赏向日葵地上部和根部吸收富集铅的含量最大，积累铅能力最强，其次为百日草，勋章菊吸收积累铅能力最弱。在Pb浓度为1000 mg · kg -1时，观赏向日葵和百日草耐性较强，可用作铅污染土壤的稳定修复植物。

| Abstract: | To study the environmental Pb toxicity , decontamination and beautification , a pot-experiment was conducted with three ornamental flowering plants to determine their Pb-absorption properties .The results showed that Helianthus annuus L .had a greater capability of accumulating Pb in shoots and roots than either Zinniaelegans Jacq or Gozania splendens .H .annuus L .andZ .elegans Jacq exhibited strong endurance to high concentration of Pb ,and were considered to be potentially applicable for soil decontamination and proper maintenance . |
