摘　　要：[目的]摸清烟台市红富士苹果叶片矿质养分状况。[方法]对烟台市的红富士果园进行了叶片矿质营养含量测定,并对其养分间相关性进行了分析。[结果]叶片中氮、磷过高,钾、钙、镁不足,其余元素基本处于适宜范围。叶片矿质养分间普遍存在协同与拮抗作用,施肥时应充分考虑。[结论]该研究为烟台果园施肥提供理论指导。[Objective]The research aimed to find out the mineral nutrient status of the Red Fuji apple leaves in Yantai City.[Method]The leaf mineral nutrient content of the Red Fuji orchard in Yantai City was determined,and the correlation between nutrients was analyzed.[Result]Nitrogen and phosphorus in the leaves were too high,potassium,calcium and magnesium were insufficient,and the remaining elements were basically in a suitable range.Synergism and antagonism were common among leaf mineral nutrients,and should be fully considered when fertilizing.[Conclusion]The study provides the theoretical guidance for the fertilization of Yantai Orchard.
