In this article,we investigated effects of lead and cadmium on the biomass of ginkgo seedlings, and roles of the seedlings in accumulation characteristics of the heavy metals and remediation of the soil contaminated by Cd~(2+) or Pb~(2+) as well as their combination.The results showed that both Cd~(2+) and Pb~(2+) significantly or very significantly reduced biomass increment of ginkgo seedlings,with Pb~(2+) more adverse than Cd~(2+).The Cd~(2+)-Pb~(2+) compound pollution further reduced biomass increment of ginkgo seedlings.The mass fractions and enrichment coefficient of Pb~(2+) and Cd~(2+) in ginkgo seedlings were in an order of root>stem>leaf,which was in favor of transportation Pb~(2+) and Cd~(2+) from root to stem and leave.The Cd~(2+)-Pb~(2+) compound pollution promoted ginkgo seedling absorption to Cd~(2+) and Pb~(2+).The capacity of the upward transport of Pb~(2+) was greater than that of Cd~(2+),which suggested an obvious dose-effect and synergistic effect.Cd~(2+) and Pb~(2+) accumulations in ginkgo seedlings were relatively large.The accumulation in roots was higher than that in stems and leaves.The ability of the absorption,transportation and accumulation of ginkgo seedlings to Pb~(2+) was relatively greater under Cd~(2+)-Pb~(2+) compound pollution.The phytoremediation efficiency of Cd~(2+) and Pb~(2+) was relatively high. In this article, we investigated effects of lead and cadmium on the biomass of ginkgo seedlings, and roles of the seedlings in accumulation characteristics of the heavy metals and remediation of the soil contaminated by Cd ~ (2+) or Pb ~ (2+) as well as their combination. These results showed that both Cd 2+ and Pb 2+ significantly or very significantly reduced biomass increment of ginkgo seedlings, with Pb 2+ more adverse than Cd 2+. ) Cd 2+ (2+) compound pollution further reduced biomass increment of ginkgo seedlings.The mass fractions and enrichment coefficient of Pb 2+ and Cd 2+ in ginkgo seedlings were in an order of root> stem> leaf, which was in favor of transportation of Pb ~ (2+) and Cd ~ (2+) from root to stem and leave. The Cd ~ (2 +) - Pb ~ The capacity of the upward transport of Pb ~ (2+) was greater than that of Cd ~ (2 +), which suggested an obvious dose-effect and synergistic effect.Cd ~ (2+) and Pb ~ (2+) accumulations in ginkgo seedlings were relatively large. The accumulation in roots was higher than that in stems and leaves. the ability of the absorption, transportation and accumulation of ginkgo seedlings to Pb ~ (2+) was relatively greater than Cd ~ (2+) -Pb ~ (2+) compound pollution.The phytoremediation efficiency of Cd ~ (2+) and Pb ~ (2+) was relatively high.
