| 摘 要： | 通过培养与盆栽试验，研究了有机肥料对污染土壤中Ｃｄ的有效性、各形态及其生物活性的影响。结果表明，有机肥料的施用明显降低了土壤中有效性Ｃｄ的含量，其中猪粪效果优于秸秆类；有机肥料的施用促使交换态Ｃｄ向松结合有机态、锰氧化物结合态以转化。相关分析表明，土壤交换态Ｃｄ和松结合有机态Ｃｄ与土壤中有效态Ｃｄ、水稻地下部分含Ｃｄ成显著或极显著正相关。

| Abstract: | Incubation and pot experiments were carried out to study the effect of organic manure on the amelioration of Cd-polluted soil. The results showed that application of organic manure could significantly reduce the content of chemically available Cd in soil. Pig manure was more effective than straw. Application of organic manure could accelerate the transformation of exchangeable Cd into WBO and OxMn. There were positive correlations between the coutents of exchangeable Cd and WBO and those of chemically available Cd and Cd taken up by rice. |
