| 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。

| Abstract: | 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 C... |
