摘要：通过盆栽试验,将雏菊、紫花地丁分别与白车轴草混种,研究不同混种方式对白车轴草铅富集的影响。结果表明:与白车轴草单种相比,混种雏菊提高了白车轴草根系生物量,混种紫花地丁降低了白车轴的草根系生物量,而混种雏菊、紫花地丁均降低了白车轴的草地上部分生物量;混种紫花地丁提高了白车轴的草根系铅含量和地上部分铅含量,分别较白车轴草单种提高了21.26%和50.34%;而混种雏菊降低了白车轴草根的系铅含量和地上部分铅含量,分别较白车轴草单种降低了3.61%和15.85%。白车轴草混种紫花地丁的富集系数和转运系数最大,分别为0.32和0.57。由此可见,白车轴草混种种紫花地丁的铅富集及提取效果最好。
Bellis perennis and Viola yedoensis were intereropped with Trifolium repens respectively to study the influence of different intereropping combinations on the Pb enrichment.The results showed that：intereropping with Bellis perennis improved the root biomass of Trifolium repens,and intercropping with Viola yedoensis reduced the root biomass of Trifolium repens.By intereropping with Bellisperennis and Viola yedoensis,the shoots biomass of Trifolium repens increased, intereropped with Viola yedoensis the lead contents in shoots and root improved by 21.26% and 50.34%.However, intereropped with Bellisperennis increased by 3.61% and 15.85%.In plot experiment intereropped with Viola yedoensis the enrichment coefficient and transfer coefficient was highest of all intereropping patterns,which reached up to 0.32and 0.57.Therefore,the Trifolium repens intercropping with Viola yedoensis was performed the best.
