摘　　要：随着土壤缺镁状况日益突出,缺镁对植物的正常生理功能和生长发育的影响越来越明显,因此镁肥的施用越来越受到重视。综述了植物镁素的生理功能,主要包括光合生理功能、酶活化功能、植物镁素对植物活性氧代谢和基因表达的影响,以及植物镁素营养诊断与镁肥的施用,为植物镁素营养的深入研究提供理论依据和参考。With the deficiency of Magnesium（Mg） more and more obviously, and it affects the normal physiological function and growth of plants. Thus, people have paid more attention for application of Mg-containing fertilizers. The physiological function, nutrition diagnosis and application of Mg in plants were reviewed in this article. In addition, the physiological function includes photosynthesis physiological function, activating function of enzyme, the impact of oxygen metabolism and gene expression in plant. It will provide bases and references for the further study of Mg in the future.
