水体镉铅铜复合污染对玉蕊生长及元素吸收的影响
Effects of Combined Pollution of Cd,Pb and Cu on Growth and Elements Absorption of Barringtonia racemosa
[目的]探究水体Cd-Pb-Cu重金属复合污染对玉蕊生长和元素吸收的影响,为玉蕊在重金属复合污染湿地修复方面的应用提供理论依据。[方法]以玉蕊为材料,采取室内盆栽试验模拟湿地环境,研究Cd-Pb-Cu复合污染对玉蕊(Barringtonia racemosa)生长、养分和重金属吸收分配的影响。[结果](1)玉蕊株高在 20 mg·L-1Cd+200 mg·L-1Pb+400 mg·L-1Cu污染水平下显著受到抑制,与CK(无污染)相比减少 12.…查看全部>>
[Objective]To explore the effects of Cd-Pb-Cu combined heavy metal pollution on the growth and element absorption of Barringtonia racemosa,and to provide theoretical basis for the application of B.racemosa in the remediation of heavy metal combined pollution wetland.[Method]The effects of Cd-Pb-Cu compound pollution on the growth,nutrient uptake,and heavy metal uptake and distribution of B.racemosa were investigated by an indoor pot experiment simulating wet…查看全部>>
