摘要
农田土壤重金属污染是影响农产品安全生产的重要因素,调控农作物营养元素可改变农作物对土壤重金属的吸收和迁移,是当前阻控农作物中重金属积累的一种有效途径。综述了农作物中重金属与营养元素、生理调节物质间的相互作用,分析了营养元素和生理调节物质阻控重金属吸收和解毒的机制,介绍了叶面生理阻控农作物重金属积累的技术发展现状。在此基础上,探讨了农作物重金属污染叶面生理阻控技术的应用前景。
Heavy metal pollution of farmland soils is an important factor that affects the safety production of agricultural products. Regulation of crop nutrition elements can change the uptake and migration of heavy metals in the crops from soil. Therefore, regulation of crop nutrition elements have been thought as an effective way to control the accumulation of he avy metals in crops. In this paper,interaction between heavy metals and nutrition elements as well as physiological control agents in crops were summarized. The uptake and detoxification mechanisms of nutrition elements and physiological control agents were analyzed. The development status of physiological control for heavy metal pollution in crops by foliar fertilization was introduced. At last,the application of physiological control technology by foliar fertilization in crops was prospected.
