摘要
以水稻土为供试土壤,进行室外盆栽试验,采用二元二次正交回归组合设计方法,研究了钢渣对Cd污染水稻土中水稻茎叶和糙米中Cd含量的影响。研究结果表明:土壤受Cd污染越严重,水稻茎叶和糙米中Cd含量越大;施入钢渣可以降低水稻茎叶和糙米中Cd含量;施入钢渣的量越大,水稻茎叶和糙米中Cd含量降低的幅度也越大。
This thesis took paddy soil as tested sample.It carried out outdoor pot experiment and adopted binary quadratic orthogonal-regression designing method.It studied slag＇s impact on Cd content of rice stem,leaf and brown rice in Cd contaminated soil.The results showed that：more serious Cd pollution the soil got,bigger content of Cd would in rice stem,leaf and brown rice;application of slag could reduce the Cd content in rice stem,leaf and brown rice;more amounts the slag be added,greater the discount rate of Cd content would be in the rice stem,leaf and brown rice.
