摘要： 植物具有富集重金属的特性,重金属在生态系统食物链中迁移、浓缩,对人类健康造成危害.因此,降低植物体内重金属含量,确保食用的安全性成为有待解决的问题.目前主要减灾手段有客土深翻的工程学方法;植物净化的生物学方法及提高植物自身抗性的生态学方法[1]. 本文运用化学调控技术,探讨了铅、镉对大豆幼苗的污染和镧(La)对大豆植株铅、镉含量及生长的影响,旨在为污染土壤上生长植物的安全性提供实验依据.此研究尚未见文献报道[2].

关键词: 大豆幼苗, Cd, Pb, 伤害, 氯化镧处理

Abstract: The contents of Cd and Pb in soybean seedling and the ecophysiological effect of La on the injury of Cd and Pb to the plant have been investigated. The results showed that the culture containing solutions of 500 mg/L of CdCl3 or 1000 mg/L of Pb(Ac)2 inhibited the growth of the soybean seedling and increased Cd or Pb content in it, and spraying one with LaCl3 solution in concentration of 30 mg/L to the seedling could reduced their injury effect and content in the plant.

Key words: soybean seedling, cadmium, lead, injury, lanthanum trichloride treatment
