| Abstract: |
| The accumulation of Heavy Metals in soil and its impact on the safety of agricultural products have attracted much attention. The bioavailability of heavy metals in soil is an important index to reflect the heavy metals in soil plant system. In this paper, a pot experiment was conducted to plant Kidney Beans (eggplant fruits and vegetables), a local representative crop in Guizhou, to study the enrichment characteristics of edible heavy metals in crops and their relationship with soil physical and chemical properties. It was found that the concentration of Cd enriched in kidney bean pods was most correlated with the concentration of Cd extracted from in situ soil solution, and the correlation with total cadmium was the lowest. The crop beneficiation coefficients of total cadmium and available cadmium were compared, which provided a basis for the establishment of soil plant heavy metal prediction model. |
