Review on Remediation of Lead Pollution in Soil by Ryegrass

Ryegrass，as a common phytoremediation of heavy metal contamination in soil，has a good research and application prospects.Remediation of lead contamination in soil by ryegrass was discussed from four directed that the induction of chelating agent on lead adsorption by ryegrass，microbial，fertilizer enhanced remediation，combined remediation of multiple heavy metals and other materials with ryegrass.Future development direction of each research direction was pointed out.
