水稻(Oryza sativa)是全球重要的粮食作物, 为了保障水稻的持续稳产, 合理的肥料施用是必要的农艺措施。磷是水稻生长所必需的大量营养元素之一, 主要通过水稻根系吸收, 而水稻长期种植在淹水环境中, 其根系表层常形成富含铁氧化物的胶膜, 其在水稻根际磷的迁移转化过程中扮演着关键角色。因此, 本文综述了水稻铁膜形成转化过程中生物及非生物因素的影响作用, 并探讨了铁膜对植物磷营养吸收及转运的影响。最后对铁膜未来研究的方向提出展望, 以期为阐明水稻根际铁磷互作提供更为深刻的理论依据。

Rice (Oryza sativa) is a globally important cereal crop, and the rational application of fertilizers is necessary agricultural practice to ensure its sustainable and stable yield. Phosphorus is one of the essential nutrients for rice, primarily absorbed through the rice roots. Since rice is often grown in flooded conditions, the root surface of rice plants often forms iron plaques rich in iron oxides, which play a crucial role in the migration and transformation of phosphorus in the rhizosphere of rice. Therefore, this paper reviews the impact of biotic and abiotic factors on the formation and transformation of iron plaques in rice and discusses the effect of iron plaques on the absorption and transport of phosphorus in plant nutrition. Finally, prospects for future research on iron plaques are presented, aiming to provide a deeper theoretical basis for understanding the interaction between iron and phosphorus in the rhizosphere of rice.
