摘  要

　　　通過盆栽試驗，研究了礦區污染土壤上施用有機肥、石灰2種改良劑對蘿卜、萵苣、青菜、白菜的地上部重金屬元素Cu、Cd、Pb、Zn積累的影響。結果表明：(1)施加改良劑對蘿卜吸收Pb和Cd起到抑制作用，并且隨著施用量的增加抑制能力增加，但對蘿卜吸收Cu起到促進作用。(2)改良劑的施加，除了施加低量豬糞對萵苣吸收Zn起到促進作用以外，其它均起到抑制作用，其中改良劑中量對抑制萵苣根系吸收Cu、Zn、Pb和Cd的效果最為顯著。(3)施加改良劑對青菜吸收Cu和Cd起到抑制作用，并且隨著施用量的增加抑制能力增加，但對青菜吸收Pb起到促進作用。(4)施加改良劑對白菜吸收Zn和Pd起到抑制作用，并且隨著施用量的增加抑制能力增加，但對白菜吸收Cu起到促進作用。

ABSTRACT

　　　The pot experiment was studied by mining area contaminated soil, organic fertilizer, lime on two improvers for turnip, lettuce, green vegetables, cabbage land heavy metal element of Cu and Pb, Zn Cd, accumulated effects. The results show that: (1) to exert improvers Pb and Cd play radish absorption inhibition, and with the increase surueyed inhibitory ability increases, but to promote Cu turnip absorption. (2) improver applied, in addition to exert a low dose of lettuce absorption pig Zn promote played outside, and others are inhibition, which improver in to restrain root absorb quantity of Cu, Zn lettuce Pb and Cd, the most significant effect. (3) to exert improvers Cu and Cd vegetables absorb inhibition, and along with has increased surueyed inhibitory ability increases, but to promote vegetables absorb the Pb. (4) to exert improvers Zn and Pd have cabbage absorption inhibition, and with the increase surueyed inhibitory ability increases, but to promote Cu cabbage absorption.
