为给利用蓖麻及类似油料能源植物修复铅、锌等重金属污染的土壤提供理论与技术依据,采用盆栽方法,将蓖麻种子栽种在由铅锌尾矿渣、泥炭土、黄土和不同体积配比的有机菌肥混配而成的基质中,观测了不同栽培基质处理的蓖麻种子萌发与幼苗生长情况,同时测量并分析了铅、锌、铜、镉在其幼苗各组织中的分布情况,以了解蓖麻对铅锌等重金属的耐受力与转运潜力。试验结果表明:蓖麻种子在纯矿渣基质和不同铅锌含量矿渣混合基质中均能萌发与生长;处理Ⅴ（60%矿渣+20%泥炭土+20%黄土）的蓖麻种子的萌芽率、发芽势、幼苗成活率及幼苗植株的生长势均较好,而处理Ⅲ（80%矿渣+10%泥炭土+10%黄土+有机菌肥）的各项...

In order to provide a theoretical and technological basis for remedying soil contaminated by heavy metal using energy oil plants, Ricinus communis seeds were planted in the mixed media of different volume ratio of leadzinc tailings, peat soil, loess and organic bacterial manure, seed germination and seedling growth in R. communis were observed. Distribution of Pb, Zn, Cu and Cd in tissues of seedling were determined and analyzed in order to learn heavy metal tolerance and transport potential of R. communis. The results demonstrate that seeds ca...
