Abstract：【Objective】Toinvestigate theeffectsofdifferentgreenmanurecrops（Vicia villosa，Vignacylindrica，and winter-summer intereropping）oncitrusyield，fruitappearance，andphysicochemicalqualityinredsoilcitrusorchards， providing scientific basis for eco-friendlysoil management in citrus orchards.【Method】Five treatments were established ina red soilhillyarea'Ehime 28′ citrus orchard：conventional management，clean cultivation with weed removal，winterplanted Vicia villosa，summer-plantedVigna cylindrica，and winter-summer intercropping.inacompletelyrandomized block design.Twelveindicators were measuredatharvest，including citrus yield，fruitappearance metrics，soluble sugar content，and vitamin C content.【Result】Winter-planted Vicia vilosa significantly increased‘Ehime 28′ citrus yield （10.93% higher than conventional management），while summer-planted Vigna cylindrica slightly reduced yield （ -1.04% ）.Summer-planted Vigna cylindrica yielded the highest average fruit weight （2O5.33 g， +11.57% ）but smallest fruit diameter （ -6.38% ）.Regarding physicochemical quality，winter-summer intercropping yielded the optimal sugaracid ratio （15.64， +16.37% ）and highest soluble sugar content （ 13.1% ）；Summer-planted Vignacylindrica significantly increased pulp-to-seed ratio （ +10.70% ）.【Conclution】Therefore，the winter-planted Vicia villsa and summer-planted Vigna cylindrica interroping systemsynergistically enhances citrus yield and flavorquality.Itrepresents an optimized choice for gren manurecultivationinredsoil citrusorchards，oferingdualbenefitsofsoil improvementandecological sustainability.
