水湿地

Wetland plants have a series of physiological and anatomical characteristics to adapt flooding habitat, e.g., their root aerenchyma and oxygen-penetrating capability can make the rhizospheric micro-environment be under oxidation condition, resulting in the formation of Fe/Mn plaques on root surface.

湿地植物具有一系列生理和结构上适应浸水环境的特征，如根系的通气组织和渗氧能力，这使得植物根际微环境处于氧化状态，这样土壤中的铁和锰会在植物根表被氧化而形成红棕色的铁锰氧化物胶膜。
