The quality of cigar tobacco is influenced by various factors, among which the ecological environment plays a crucial role. However, it remains uncertain whether Yunnan, known for its diverse environment, suitable growth tobacco. Therefore, objective this study was to investigate disparities in soil physicochemical properties and microbial community across three ecoregions namely Longyang, Ruili Tengchong, located southwest China. Furthermore, we aimed analyze correlation these factors with growth. results showed that Longyang exhibited higher values pH (7.78±0.11), available potassium (735.72±198.96), cellulase (1.07±0.23) polyphenol oxidase (0.39±0.001) compared promoting (P<0.05). Additionally, demonstrated greater fungal diversity but lower bacterial Correlation analysis structural equation modeling further confirmed primary factor influencing (r=0.802, P< 0.01). Moreover, bacteria sensitivity fungi, structure significantly plant (P< 0.05). In summary, alkaline enriched organic matter potassium, favorable conditions thereby proved more
