目前,我国大部分受到重金属污染的农田土壤仍用作农作物生产,导致重金属通过被污染的农产品进入人体的风险急剧增加。大量研究表明,土壤施肥能通过改变土壤理化性质,来影响重金属的生物有效性。鉴于此,简要综述了1997-2014年重金属对作物生长的影响以及施肥对作物富集重金属的影响研究进展,并对该领域今后的研究方向提出了展望。
At present, most of the soil contaminated by heavy metals in our country is still used for crop production, leading to a sharp increase in the risk of heavy metals entering the human body through contaminated agricultural products. Numerous studies have shown that soil fertilization can affect the bioavailability of heavy metals by changing the physical and chemical properties of soil. In view of this, a brief review of the impact of heavy metals on crop growth from 1997 to 2014 and the impact of fertilization on the accumulation of heavy metals in crops are briefly reviewed. The future research directions in this area are also presented.
