摘要：
Lime and Si fertilizer are effective amendments for alleviating Cd accumulation in crops. In this study, two Cd-polluted typical soils from different regions in China were sampled to conduct a pot experiment. The effects of two soil amendments [calcium oxide of quicklime (SH) and Si–Ca–Mg fertilizer (GF)] on the distribution of Cd fractions in soil with and without rice-planting treatment and on Cd uptake and accumulation in rice were investigated. The results showed that SH and GF application significantly reduced Cd accumulation in rice in ...
