农作物镉污染调控关键技术研究进展

    Research Progress on the Key Techniques for Regulating and Controlling the Cadmium Pollution in Crops

    • 摘要: 重金属是影响土壤环境质量的主要污染物。镉由于移动性强、生物毒性高等特点,容易被作物吸收、迁移,从而通过食物链传递影响人体健康。在系统查阅国内外文献的基础上,从镉低积累作物品种的选育、镉污染土壤修复及农艺调控技术等方面综述农作物调控镉污染的关键技术,并探讨未来农作物镉污染调控的研究重点及应对策略,为镉污染耕地作物的安全生产以及农业可持续发展提供参考。

       

      Abstract: Heavy metals are the main pollutants affecting the soil environmental quality. Cadmium (Cd) is easily to be absorbed and transported by the crops due to its strong transferability and high biological toxicity, thus affecting the human health through the food chain. Based on a systematic review of domestic and foreign literatures, the key technologies for regulating and controlling the cadmium pollution in crops were reviewed from the aspects of the selection of crop varieties with low Cd accumulation, the remediation of Cd contaminated soil and agronomic control techniques. In addition, the research focus and countermeasures for regulating and controlling the cadmium pollution of crops in the future were discussed, so as to provide reference for the safe production of crops in the cadmium-contaminated cultivated land and the sustainable development of agricultre.
