摘要:
采用野外试验和测定，研究了4种植物对毛竹笋林地重金属污染的修复效果。结果表明：在毛竹笋林地栽植重金属超积累植物可以消减土壤中特定元素的含量。东南景天对土壤中Pb、Cd和Zn有较强的积累效应，一个生长周期中，3种元素累积量分别为50.4、33.0、73.1 mg·kg-1，土壤中的含量分别降低了8.7%、10.5%、4.0%；蜈蚣草一个生长周期可分别积累Zn、As82.7 mg·kg-1和72.1 mg·kg-1，土壤中Zn和As的含量分别降低了5.3%和20.0%。重金属在植物中的累积速度随植物的生长时间而不同，表现为前期、中前期积累较快，后期积累较缓。
Abstract:
Phytoremedication of heavy metal pollution in bamboo forest land was studied by four green plants. 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 rhizosphere，and 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.
