Abstract：ToclarifytheeffectsofdiffrentmicrobialinoculantsontheyieldofbabyChinesecabbageinvegetable productioninGanzouDistrict，afieldexperimentwasconductedintheHexiCoridorsGanzhouDistrict.Thecontrolreatment applied only chemical fertilizers （urea at 375kg/ha ，superphosphate at 241.5 kg/ha，and potassium sulfateat 300 kg/ha），while 4 treatmentsadeddrentfertls，arboneilcncmetlvceaotiuousopina，lay totheend，andTukangyuanmicrobialagent，achat3kg/h，inaditiontotechemicalftilizers.Thesudydeteindte efectsftheiofertilizersonpototeticharacteristisantioidanteeactivities（e.gperoxidse）andyildots.
