植物体内磷铁平衡与缺铁胁迫的关系研究进展

Research Progress on the Relationship between P-Fe Balance and Fe Deficiency Stress

缺铁是导致我国华北、东北及西北地区作物减产的重要因素之一。大量研究表明植物体内铁缺乏与磷的含量密切相关,磷和铁互作形成沉淀导致这两种元素的有效性都降低。从植物缺铁适应机制、磷铁互作研究现状以及营养高效利用三个方面进行了整理和总结,探讨铁高效利用与磷铁互作之间的关系,并对养分平衡规律的研究提出了一些建议,旨在为科学施肥提供理论依据。

Fe-deficiency is the major cause of reduced crops yield in North,Northeast,and Northwest China. Studies showed that the Fe-deficiency is associated with P element content,the precipitation induced by P-Fe interaction results in effectiveness reduction of the two elements. Therefore,the relationship between P-Fe interaction and Fe efficiency was discussed,by combining and summarizing from research status of plant adaptation mechanism under iron deficiency,P-Fe interaction,and nutrition using efficiency. Some suggestions were made for the study about nutrients balance rule,hope to provide theoretical basis for scientific fertilization.
