4种植物对毛竹笋林地重金属污染土壤的修复作用研究
Phytoremedication of Heavy Metal Pollution in Bamboo Forest Land by Four Green Plants
摘要
Abstract
Phytoremedication of heavy metal pollution in bamboo forest land was studied by four green plains. The results showed that the hyperaccumulator could reduce the content of specific elements in soil of bamboo forest. Pb, Cd and Zn in soil could be super-accumulated by Sedum alfredii, and these elements could be accumulated up to 50. 4 mg ? Kg"1, 33. 0 mg ? Kg"1 , 73. 1 mg ? Kg"1 through one growth cycle of rhizosphercand the 3 elements reduced by 8. 7%, 10. 5%, and 4. 0%, respectively in test plots. Zn and As in soil could be super-accumulated by EremochLoa ciliaris, and these elements could be accumulated up to 82. 7 mg ? Kg"1 , 72. 1 mg ? Kg"1 through one growth cycle of E. Ciliaris,and these elements in the soil reduced by 5. 3% and 20. 0% in test plots. The of heavy metal enrichment of the plants varied in different growth time, and rapid accumulation in the early and medium-term, more moderate accumulation in later phase.关键词
