采用盆栽试验,研究在铅锌尾矿重金属胁迫下,秸秆对蓖麻幼苗生物量、叶片内丙二醛（MDA）含量和超氧化物歧化酶（SOD）、过氧化氢酶（CAT）、过氧化物酶（POD）活性以及重金属积累的影响。结果表明:在铅锌尾矿砂中添加秸秆能显著增加蓖麻的株高、根长和生物量;使蓖麻叶片中MDA含量和SOD、CAT、POD活性分别比对照降低了48.08%、7.28%、28.60%和4.74%;铅锌尾矿砂中有效态Pb、Zn、Cd含量显著降低,且蓖麻对Pb、Zn、Cd的积累量也显著下降;蓖麻叶片POD、SOD活性与叶片中Pb、Zn、Cd含量呈极显著正相关,蓖麻积累的重金属含量与尾矿砂中有效态重金属含量呈显著或极显著正相关。

Pot experiments were carried out to investigate the effect of straw addition on biomass, contents of malonyldialdehyde （MDA）, activities of superoxide dismntase （SOD）, catalase （CAT）, peroxide enzyme （POD） and the accumulation of heavy metals （Pb, Zn, Cd） in Ricinus communis under the stress of Pb/Zn mine tailing. The results indicated that straw addition significantly increased fresh weight, height and root length of Ricinus communis. The contents of MDA and the activities of SOD, POD, CAT in the leaves of Ricinus communis under the ...
