Abstract:

通过褐土不同浓度的磷培养试验,研究了不同含磷量土壤对锌、镉及锌镉共存时的吸附、解吸影响,以阐述磷与锌镉在土壤系统中的交互作用机制。结果表明,不同含磷量的土壤对不同浓度的锌和镉吸附解吸时,在Zn10条件下,土壤对锌的吸附量先降低后升高,锌解吸量随着土壤中磷含量的增加先升高后降低逐渐趋于平稳。而在Zn80条件下,土壤对锌的吸附量有明显下降趋势,而解吸量随着磷含量的增大先升高后降低,在土壤速效磷含量为89.5mg·kg-1(添加磷水平360mg·kg-1)时解吸量达到最大值;在相同磷水平下,随着外加镉浓度的增大,锌的吸附量明显降低。在Cd3处理下,镉的吸附量随磷水平的增大而减小,而Cd30处理下,镉的吸附量随磷水平的增大而增大;但相同磷水平下,随锌浓度的增大,镉的吸附量都明显降低。镉的解吸量随速效磷含量和锌浓度的增加而增大。
