ABSTRACT：Theapplicationoforganic-inorganic compound fertilizers can improve soil microbialcommunities.The study investigated theeffectsof differentformulationsoforganic-inorganiccompoundfertilizersontherhizosphere soilmicrobial community structure in tobacco under upland and paddy-dryland rotation（paddy fields）planting paterns in Fuchuan County，Hezhou，Guangxi.The results showed therhizosphere fungi andbacteria exhibited diferential sensitivity to organic-inorganic compoud fertilizer formulationsunderuplandand paddy-upland rotation cultivation modes.In upland fields，teaseed mealcompound fertilizersignificantly promotedsynergistic proliferationofboth fungaland bacterial communities.Conversely，under paddy-upland rotation，soybean mealcompoundfertilizer selectively enhanced the abundance ofrhizosphere bacterialcommunities.Notably，neither tea seed meal（in uplandfields）norsoybean meal（in paddy fields）formulations significantly afected thegrowthof the pathogenic bacterium Ralstonia sp..These findings establishedatheoretical foundation fortargetedoptimizationof organic-inorganiccompound fertilizer formulationsinthe Hezhou tobacco-growing region of Guangxi.
