| 摘 要： | 通过盆栽试验,研究在镉污染水稻土上施用硅素物质对水稻植株不同部位镉含量及土壤中镉形态的影响.结果表明:加入硅素物质降低了水稻各部位镉含量.随着硅肥施入量的增加,水稻各部位的镉含量呈现降低趋势,土壤pH值升高,土壤中可交换态、碳酸盐结合态镉含量呈现降低趋势,铁锰氧化物态、有机结合态镉含量呈现增加趋势.

| Abstract: | Pot experiment was adopted to study the effect of silicon material on Cd content in rice and existing form of Cd in soil.The results showed that the concentration of Cd in paddy rice decreased with the treatment of fertilizer application.With the increase of the silicon materials input,the Cd content in various spots of paddy rice presented reducing tendency,the soil pH value elevated,the content of exchangable form,carbonate form and residual form of Cd decreased,but the content of Fe-Mn oxide and Cd bound to organic matter increased. |
