| 摘 要： | 采用盆栽法研究锰尾渣改良对外来植物加拿大一枝黄花(Solidago canadensis)的生长及其富集金属的影响.基质全为锰尾渣时,加拿大一枝黄花的株高、生物量和叶绿素含量小于对照,但差异不显著.锰尾渣经土壤改良后,其株高、生物量和叶绿素含量都显著大于对照.锰尾渣胁迫增强其体内SOD活性.随锰尾渣含量增加,其根系活力先增加而后下降.除T100处理(锰尾渣未经改良)外,在其它处理中,其根系耐性指数均大于1.其根部能富集锰和镉,其地上部分铅含量为1089.45～1731.10mg/kg,铅转运系数大于1.因此,加拿大一枝黄花具有铅富集植物的特性.实验结果表明加拿大一枝黄花对锰尾渣耐性较强,能富集锰、镉和铅;土壤改良锰尾渣有利其生长.加拿大一枝黄花竞争排斥性强,会造成生境退化,因此,植被重建时,要加强对其管理. |

| Abstract: | Pot experiments were conducted to investigate influence of amendment of Mn mining tailing on growth and heavy metal accumulation by Solidago canadensis. Seedlings of S. canadensis were transplanted into pots which contained Mn mining tailing diluted with various portions of clean soil. After 90 days, seedlings were harvested. In this experiment, we measured many parameters including seedling height, biomass, chlorophyll content, SOD activity, root activity, root tolerance index, and aboveground biomass allo... |
