With the increasing oil consumption, the problem of soil pollution needs to be solved urgently. Combining plants and arbuscular mycorrhizal fungi is considered a potentially effective green technology for the remediation of petroleum- contaminated soil. Arbuscular mycorrhizal fungi form symbionts with host plants, which can improve plant rhizosphere microenvironment, enhance plant resistance to stress, activate soil microorganisms, and play a positive role in removing and degrading petroleum contaminants. Based on an overview of the environmental hazards and treatment status of oil pollution, this paper introduced the remediation technology of arbuscular mycorrhizal and its application, summarized the effects of oil-polluted concentration, host plants, inoculation methods, and environmental conditions on the remediating efficiency, analyzed the direct and indirect dissipation mechanism of this symbiont, and proposed the prospects for future development. The purpose of this paper is to promote the application and development of arbuscular mycorrhizal assistant phytoremediation technology.
