摘　　要：甘蔗是我国重要的糖料作物,主要于种植在我国西南、华南地区,该区域为酸性土壤,土壤镁素缺乏,且蔗园镁肥投入低,缺镁已成为限制我国甘蔗产量和品质的重要因子。因此,甘蔗镁素营养机制研究与镁肥科学管理对促进甘蔗提质增效具有重要作用。本文从我国蔗区土壤镁供给状况、甘蔗镁需求特征、甘蔗镁营养生理及镁肥施用效果等方面综述了甘蔗镁营养研究工作的进展。最后针对我国甘蔗生产中镁素亏缺问题,提出镁肥科学施用方法,为我国甘蔗产业可持续健康发展提供技术支撑。Sugarcane is a crucial sugar crop in China,primarily cultivated in the southwest and southern regions.These areas are characterized by acidic soil,magnesium deficiency in soil,and low application of magnesium fertilizer in sugarcane plantations.As a result,the scarcity of magnesium has emerged as a significant limiting factor for both the yield and quality of sugarcane in China.Therefore,research on the mechanism of sugarcane magnesium nutrition and scientific management of magnesium fertilizer play a pivotal role in enhancing the quality and productivity of sugarcane.In this paper,the progress of research work on sugarcane Mg nutrition is reviewed from the soil Mg supply situation in sugarcane areas in China,the characteristics of sugarcane Mg demand,the physiology of sugarcane Mg nutrition and the effect of Mg fertilizer application.Finally,in response to the problem of magnesium deficiency in sugarcane production in China,the scientific application method of magnesium fertilizer is proposed to provide technical support for the sustainable and healthy development of China's sugarcane industry.
