Abstract：Toclarifytheeffects oforganic fertilizerson thephysicochemical propertiesand microbial environmentof soilsin tea gardensandthesuroundingareas，this studysystematicallyevaluatedthesoilphysicochemical properties，microbialcommunitystructure，and teaqualityusing inductivelycoupled plasma massspectrometry（ICP-MS）andhighthroughputsequencing technologies.Theresultsindicatedthatcomparedtotheapplicationofchemicalfertilizers，theuseof organicfertilizerssignificantlyincreasedtheaminoacidcontentintealeavesandreducedthecaffeinecontent.TheapplicationoforganicfertilizerssignificantlyincreasedthetotalpotassiumcontentandpHvalueinteagardensoilbutdecreasedthetotal phosphorus content and availablephosphorus content. Theapplicationof organic fertilizerssignificantlyreduced the contents of Cu，Pb and Cd in tea garden soil，markedlyincreased the relative abundance of bacteria suchas Acinetobacter，Burkholderia，Streptomyces，Nitrospiraand Rhizobium，anddecreased therelativeabundanceofAcidothermus，Mizugakiibacter，Variibacter，Acidobacterium， and Acidicaldus.In conclusion，the application of organic fertilizers improves the soil environment in tea gardens，promotes theenrichmentof beneficial microorganisms，thereby enhancing teaqualityandreducing heavymetalcontamination.Thefindingsofthisstudyprovidevaluableinsightsfortheecologicalmanagementofteagardensandtheadvancement of sustainable agricultural development.
