Mirabilis jalapa L. has strong environmental adaptability and reproductive ability, and is distributed all over the country. The use of ornamental plants for phytoremediation of polluted soil can not only remove pollutants in the environment, but also green, beautify and purify the environment. The germination rate of M. jalapa seeds decreased significantly with the prolongation of storage time, and the seeds germinated satisfactorily within 9 months. The germination rate was reach peak at the sixth day. The plant height and root length of M. jalapa grown on different soil substrates has shown different trend. The fleshy root propagation survival rate of M. jalapa was significantly higher than that of seed and stem cutting propagation. The main enrichment of Cd was in root. The survival rate of fleshy root reproduction was no significant effect in different growth substrates. Therefore, fleshy root propagation was the best way for M. jalapa to grow on different substrates. And the application prospects of M. jalapa as a remediation plant should be further studied.
