| 摘 要： | 通过研究红花酢浆草和油菜对镉的吸收状况发现，土壤中镉的浓度会对这两种植物的生长产生影响，油菜体内的镉含量和地上部分的富集系数都大于红花酢装草，但是红花酢浆草的转运系数大于油菜，说明油菜对镉的吸收能力要比红花酢浆草强，但是转运能力不如红花酢浆草。图2，表3，参12。 |

| Abstract: | The characters of absorbing Cd in Brassica campestris and Oxalis rubra are found based on the analysis. The density of Cd in soil could affect the growth of the two plants. The CA content in the body of Brassica campestris is higher than which of Oxalis rubra, and the BCF of above-ground tissue of Brassica campestris is more than which of Oxalis rubra. However, the TF of Oxalis rubra is more than which of Brassi-ca campestris. All these show that the ability of absorbing Cd of Brassica campestris is stronger than which of Oxakus rubra, but it' s ability of transforming CA from down-ground tissue to above-ground tissue is weaker than Oxalis rubra. |
