【摘要】 调查了铜矿产区土壤的 Cu、Cd、As污染 ,研究了它们对水稻的复合污染生物效应 .结果表明 :水稻对Cu没有富集作用 ,对 Cd、As有明显的富集作用 ,但多聚集于根部 .表土层 ( A层 )土壤中的 Cu含量与水稻样根、茎、稻粒中 Cu含量有明显的相关关系 ,水稻吸收 Cd、As与 A层土壤中的 Cd、As含量无明显的相关关系 ,但水稻根与稻粒中的 Cd含量之间存在明显正相关更多还原

【Abstract】 The soil pllution of copper mineral area and biologic effect of combined pollution to rice resulting from Cu,Cd and As are investigated.The results show that the rice does not have enrichment of Cu. However, it can obviously enrich Cd and As. Cd and As gather mostly at the roots. The content of Cu in the topsoil has the clear relation with the content including the root, stem and grain of rice. And the content of Cd and As absorbed by rice has the unclear correlative relation with the content in the topsoil. But the relation of Cd between the root and the grain of rice is obviously correlative.更多还原
