摘要
[目的]为寻找铅污染土壤净化和景观化的材料。[方法]采用盆栽方法,研究了3种苋科花卉在铅污染条件下对铅的富集特征。[结果]3种观赏花卉中火炬鸡冠地上部吸收富集铅的量最大,积累铅能力最强,其次为红穗苋,红苋菜吸收积累铅能力最弱。[结论]火炬鸡冠耐性较强,可用作铅污染土壤的稳定修复植物。
[Objective] The research aimed to look for the material of purifying and beautifying Pb-contaminated environment.[Method] Three ornamental flowers were screened to determine their absorbing characteristics for Pb and their endurable characteristics by pot-culture experiment.[Result] Celosia cristata pyramidalis had a stronger capability of accumulating Pb in shoot than Amaranthus hypochondriacus and Amaranthus mangostanus L,which had the weakest accumulating ability.[Conclusion] Celosia cristata pyramidalis exhibited stronger endurance to Pb,which could be used for soil stabilization remediation.
