Abstract
Monoculture and intercrop of hyperaccumulator Solanum nigrum L. with low accumulation Welsh onion Renbentieganchongwang were conducted. The results showed that the remove ratio of S. nigrum to Cd was about 7% in intercrop plot when top soil (0-20 cm) Cd concentration was 0.45-0.62 mg kg(-1), which did not significantly impact the yield of low accumulation Welsh onion compared to the monoculture. The consistency of remove ratio in practice and theory indicated the remediation of S. nigrum to Cd was significant. The Cd concentration and yield of Welsh onion were not affected by the growth of S. nigrum either in intercrop plot. The Cd concentration in edible parts of Welsh onion was available either. In short, inter-planting hyperaccumulator with low accumulation crop could normally remediate contaminated soil and produce crop (obtain economic benefit), which may be one practical pathway of phytoremediating heavy metal contaminated soil in the future.
