摘　　要：针对铜、铅锌、锡3种尾矿,选用能源甘蔗在3种不同改良方式的盆栽试验,不同盆栽处理以m(尾矿砂)∶m(水稻土)分别为7∶3,8∶2,9∶1配比混合而成。结果表明,除Cu3有减产外,其余处理均比对照增产,其中增产较大的处理是Sn2、Cu1和Sn1。甘蔗的根系除Pb1处理,其余处理均比对照增产。不同配比的尾矿砂对制糖工艺指标糖分、纤维分、简纯度、还原糖有不利的影响,但与对照相比差异不明显。综合考虑尾矿砂和水稻土的配比,铜尾矿与土壤的配比用8∶2,锡和铅\锌尾矿与土壤的配比用9∶1较合适(重量比)。该研究结果对指导能源甘蔗在尾矿山上的植物修复有一定的指导意义。Pot eXperiment was conducted using three kinds of mine tailings Cu, Pb/Zn and Sn were mixed with soil from paddy by 7： 3, 8： 2, 9：1 for each tailing as energy cane growing medium, The result indicated that most of the medium positively affected on cane yield except for the treatment of Cu3, Sn2, Cul and Snl indicated the most positive effect on cane yield. Most of the treatment have positive effect on root yield except for Pbl. Various ratio of mine tailings negetively affected quality index such as sucrose content, fibre content, apparent purity and reducing sugar while the difference was not significant compared with check. The ratio of mine railings to paddy soil when 8：2 for Cu, or 9 ： lfor Sn. Pb/Zn are suitable. This result could be of goed reference for growing engery cane in field with mine tailings.
