The purpose of the study was to assess the possibility of cultivation of maize (Zea mays L.) on marginal soils polluted by heavy metals. The research was conducted on a Stagnic Luvisol soil that varied in terms of pH and the degree of heavy metal (cadmium [Cd], copper [Cu], and zinc [Zn]) contamination. The usefulness of maize for cultivation on contaminated soils was assessed on the basis of indicators such as tolerance index (TI), translocation factor (TF), bioaccumulation coefficient (BAC), and bioconcentration factor (BCF). Heavy metals taken up by the maize plant are accumulated mainly in the roots and in a small amount transported to the aboveground parts of the plant. The series of decreasing concentration of heavy metals (Cd, Cu, Zn) in the dry mass of maize plants is as follows: roots > leaves > stalk > ears. The TF, BAC, and BCF values indicate that maize can be used for phytoextraction of metals such as Cd and Zn, and for phytostabilization of Cu in soils contaminated with this element.

重金属污染边缘土壤修复对农业生产的影响

该研究的目的是评估在被重金属污染的边缘土壤上种植玉米 (Zea mays L.) 的可能性。该研究是在 Stagnic Luvisol 土壤上进行的，该土壤的 pH 值和重金属（镉 [Cd]、铜 [Cu] 和锌 [Zn]）污染程度各不相同。玉米在污染土壤上种植的有用性是根据耐受指数（TI）、易位因子（TF）、生物积累系数（BAC）和生物富集因子（BCF）等指标进行评估的。玉米植株吸收的重金属主要在根部积累，少量转移到植株的地上部分。玉米植株干物质中重金属（Cd、Cu、Zn）浓度递减序列为：根>叶>茎>穗。TF、BAC、
