作物吸收富集镉研究进展

土壤镉污染已经成为一个重要的环境问题，植物镉的吸收富集已引起全世界学者的关注。回顾和总结了国内外学者对几种作物镉积累的特点，对比分析了它们可食部位镉的富集系数，并提出了植物吸收积累镉的可能的机制及降低植物镉吸收的方法，最后提出了降低植物镉吸收方面存在的问题和对未来的展望，为今后降低植物镉吸收、防治植物镉污染提供重要的理论指导和思路。

Research Advances on Cadmium Absorption and Accumulation of Plant

The pollution of cadmium in the soil has become a major problem in the environment. The cadmium absorption and accumulation has been focused by many scientists from all over the world. In this article, the general research progress of accumulation of cadmium in various agricultural crops was reviewed and presented. And then, the accumulation coefficient of cadmium in the soil was analyzed. Moreover, the actual mechanism of cadmium absorption and accumulation in plants was characterized and a strategy to reduce the absorption of cadmium was developed. At last, the existing problems and its resolvent had been shown. So this present investigation will provide necessary ideas to reduce the cadmium absorption and over accumulation in the plants.
