In view of the unreasonable application of potassium(K+)and magnesium(Mg2+)fertilizer in potato production,as well as the unclear relationship between potassium and magnesium nutrient interaction.Based on the domestic and international researches,this manuscript systematically reviewed the effects of potassium and magnesium interactions on growth and development,morphology,nutrient uptake and transport,tuber yield and quality formation,which further analyzes the range of K+/Mg2+ratios in soil that suitable for potato growth.Further research trend of potassium and magnesium interactions for high quality,yield,and nutrient efficiency with synergistic enhancement is proposed in potato,which provides reference for the reasonable application of potato potassium and magnesium fertilizer in potato production.
