Exogenous silicon has been shown to enhance plant growth and alleviate heavy metals toxicity, but the regulation mechanismof silicon on cadmiummigration and transformation in the soil-rice systemis still unclear, which isworth further study. In this study, a pot experiment was carried out to explore the influence of different doses (0, 1 and 5%) of mineral silicon on soil properties, nutrient availability, rice growth, soil enzyme activities, Cd bioavailability, and uptake and accumulation of Cd in high-accumulating (H) and low-accumulating (L) rice cultivars grown in contaminated soils.
