Soils play a dominant role in supporting the survival and growth of crops and they are also extremely important for human health and food safety. At present, the contamination of soil by heavy metals remains a globally concerning environmental issue that needs to be resolved. In the environment, iron plaque, naturally occurring on the root surface of wetland plants, is found to be equipped with an excellent ability at blocking the migration of heavy metals from soils to plants, which can be further developed as an environmentally friendly strategy for soil remediation to ensure food security. Because of its large surface-to-volume porous structure, iron plaque exhibits high binding affinity to heavy metals. Moreover, iron plaque can be seen as a reservoir to store nutrients to support the growth of plants. In this review, the formation process of iron plaque, the ecological role that iron plaque plays in the environment and the interaction between iron plaque, plants and microbes, are summarized.
土壤在支持作物的生存和生长方面起着主导作用，对人类健康和食品安全也极为重要。目前，土壤重金属污染仍然是一个全球关注的需要解决的环境问题。在环境中，发现湿地植物根表面自然形成的铁膜具有出色的阻止重金属从土壤向植物迁移的能力，这可以进一步发展成为一种确保食品安全的土壤修复环境友好策略。由于其大的比表面积多孔结构，铁膜对重金属表现出高结合亲和力。此外，铁膜可被视为储存养分以支持植物生长的库。在这篇综述中，总结了铁膜的形成过程、铁膜在环境中所起的生态作用以及铁膜、植物和微生物之间的相互作用。
