硅肥抑制作物吸收重金属的研究进展

The Research Progresses on Silicon Fertilizer Controlling the Absorption of Heavy Metal in Plant

硅肥能降低重金属对作物的毒害,对减小重金属的污染起到了一定的作用。硅抑制作物吸收重金属的机理主要涉及硅与重金属的螯合作用、土壤理化性质的改变。在此,系统阐述了重金属对作物的毒害以及硅抑制作物吸收重金属的作用机理,并且综述了硅缓减重金属毒害的研究进展。

Silicon fertilizer can reduce the toxicity of heavy metal, and plays an important role in reducing heavy metal pollution. The mechanism is involved chelation with heavy mental and changes of physicochemical properties in soil. The position function of heavy metal and the mechanism of silicon are reviewed. The latest advance in this field is summed up.
