Phytoremediation is a low-cost and environmentally friendly remediation technology. It often uses enriched or even highly enriched plants to enrich and remove heavy metals in soil. The phytoremediation method does not destroy the structure of the polluted soil, has less impact on soil microorganisms and animals, and has the advantages of less investment in governance. Phytoremediation of polluted soil can beautify the environment at the same time. It is a promising, safe, reliable and emerging green bioremediation technology. Therefore, this paper uses phytoremediation technology to control soil heavy metal pollution. Due to the plant's strong ability to enrich a variety of heavy metals. In this paper, plants such as Phyllostachys vulgaris were selected to carry out simulation experiments on the soil of an industrial area, and the enrichment effects of six types of pollution indicators such as Pb, Zn, Cr, As, Cd, and Cu in the soil samples and the removal of heavy metals by Phyllanthus sinensis were analyzed. The results showed that P. chinensis had better enrichment effect on Cd, As, Pb, and Cu, and better removal effect on heavy metals such as Cd, Pb, and Cu.
