摘　　要：水稻(Oryzasativa)是全球重要的粮食作物。合理施肥是保障水稻持续稳产的必要农艺措施。磷是水稻生长必需的营养元素之一,主要通过水稻根系吸收。而水稻长期生长在淹水环境中,其根系表层形成富含铁氧化物的胶膜,并在水稻根际磷的迁移和转化过程中扮演关键角色。该文综述了生物和非生物因素对水稻铁膜形成和转化的影响,探讨了铁膜对磷吸收及转运的影响,并对后续研究提出建议,旨在为阐明水稻根际铁磷互作机制提供理论依据。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,pri-marily absorbed through the rice roots.Since rice is mostly grown in flooded conditions,the root surface of rice generally forms iron plaques rich in iron oxides,which play a crucial role in the migration of inorganic phosphorus in the rhizosphere of rice.This paper reviews the impact of biotic and abiotic factors on the formation of iron plaques in rice and discusses the effect of iron plaques on the absorption and transport of phosphorus in plant nutrition.Furthermore,we discuss the prospects of future research on iron plaques,aiming to provide clues for our further understanding of the interactions between iron and phosphorus in the rhizosphere of rice.
