중금속 오염토양 정화에 영향을 미치는 봉의꼬리(Pteris multifida Poir.)와 쑥(Artemisia princeps Pamp.)의 혼합식재 비율 KCI 등재
Effect of Mixed Planting Ratios of Pteris multifida Poir. and Artemisia princeps Pamp. on Phytoremediation of Heavy Metals Contaminated Soil
pp.160-166
This study was performed to develop the efficient phytoremediation model in the paddy soil contaminated with heavy metals by cultivating Pteris multifida and Artemisia princeps with different mixing ratios (1:0, 8:1, 6:1, 4:1). As a result of investigating the heavy metal accumulation of each plant per dried material (1 ㎏), content of arsenic and cadmium was the highest in aerial part of P. multifida (169.82, 1.70 ㎎·㎏-1 DW, each) among the treated group. Lead content was the highest (12.58 ㎎·㎏-1 DW) in the aerial part of P. multifida cultivated with 8:1 mixed planting. But the content of copper and zinc was the highest (33.94, 61.78 ㎎·㎏-1 DW, each) in the aerial part of A. princeps with 8:1 treatment. Regardless of heavy metals, plant uptake from the 1 ㎡ soil was the highest in 4:1 mixed planting group, which showed the best yield of A. princeps.
