Abstract：【Objective】The impactof different fertilizer combinations onthe qualityand yieldofFujiapples was investigatedtodentifyhighqualityandhighyieldfertilizationschemes，therebyprovidingascienticbasisforoptimizingFujiapplefer tilization managementpractices.【Methods】Fourfertlizationtreatmentcombinations weresetup，i.e.，thecombinedfertilizationschemeofchemicalfertilizer，bacterialfertilizer，oilresiduefertilizerandmieralfulvicacidpotassiumfertilizrwereset upto measure fruit yield，fruit hardnessand britleness，coloringandotherindexes，thechangesofsoilnutrientsand pHwere also analyzed.【Results】Theresultsshowed thatamong thefourdiferent fertilizeraplicationschemes，theco-applicationof chemical fertlizerandoilresiduefertilizer（F3）hadthe mostsignificant efectonimproving thecomprehensivequalityand yield of apple fruits.UnderF3 treatment，yield perapple treecanreach 31.43kg.Compared with thecontrol group（CK），the transverse diameter and longitudinal diameter of the fruit increased by 7.94% and 9.06% ，respectively，and the fruit type was fuller. Fruit hardness up to 8.71kg/cm2 . The quality fraction of soluble solids content increased by 8.20% ， and the solid-acid ratio increased by 55.58% . Vitamin C content increased by 7.88% . The soil organic matter content was the highest，reaching 20.84g⋅kg-1 . 【Conclusion】Among allthe treatments，the synergistic fertilization scheme of chemical fertilizer and oil residueferilizerhadthe mostobvious efectontheimprovementof yield，fruitappearance，intrinsicflavor，nutritionalqualityand soil chemical properties of Fuji apple.
