The results showed that compared with NPK，NPKM and NPKM increased the pepper yield by 3 1 % ，reduced the incidenceofalseasdealoolltetplantsstuakedalolngtdd thenitratecontentoffuits.ComparedwithNK，NKBsigncantlyicreasedthetotalnrogn，totalpospous，dlable nitrogenisoilndireasdteainContenoffruits.Multipleplatgrowthritsndsilrtilityidicatorsweesiicatly correlated withthefruityield，fruitqualityanddiseaseincidence.Insummarytheapplicationofpigmanureandbiocharcould improvesoilfertilitywhiledecreasingthe incidenceof typicalsoil-borne diseases，thusimproving thefruityieldand qualityand promoting the green， safe， and sustainable development of the pepper industry.
