Abstract：Using Meidu watermelonasexperimental material，four treatmentswereestablishedwith clearwateras the control（CK）.Thestudyinvestigatedtheefectsofthreemicrobialfertilizers[Arbuscularmycorhizalfungi inoculant （AMF），Bacillus inoculant（BAC），and combined AMF and BAC application（MIX）]on watermelon growth，fruit quality， yield，and mineral element absorption.Theresults demonstrated that the mixed inoculant（MIX）at the seedling stage significantlyenhancedvinelength，stemdiameter，leafarea，andchlorophyllcontent（SPADvalue）at35dayspost-treatment compared to CK，with increases of 23.33% ， 12.58% ， 49.88% and 23.70% ，respectively.TheMIX treatment also exhibited optimal performance in single fruit mass （7.37kg） ，vitamin C content （13.87mg⋅100g-1） ）and soluble solids content（ 14.72% ）in the center of watermelon flesh.Furthermore，application mixed inoculant at the seedling stage showed the highest N，P，and K contents in watermelon flesh，which were12.57，1.79，and 14.83g⋅kg-1 ，respectively and the applicationof microbial fertilizerattheseedling stage hasabeterefectonimproving thesingle fruit weightandfruit quality ofwatermelonthan that attheflowering stage.Comprehensive analysis revealed significantcorrelations between microbialfertilizersapplicationandimprovementinplant growth，mineralelementuptake，andfruitquality，thecombined inoculantachievingthemost pronounced efectsandtheapplication effctattheseedling stage is beterthanthatat theflowering stage.
