Pogostemon cablin (Patchouli), an essential medicinal plant in the Lamiaceae family, faces significant challenges under continuous cropping (CC) obstacles. This study examined rhizospheric soil bacterial communities of patchouli four different CC years, zero (CK), one (T1), two (T2), and three (T3) years through high-throughput 16S rRNA gene amplicon sequencing. Results showed long-term led to properties enzyme activity shifts. Key parameters such as pH total potassium (TK) decreased, while ammonium nitrogen (NH4+–N), organic carbon (SOC), nitrate (NO3−–N), available (AK), phosphorus (AP), (TN), (TP) increased over years. Enzyme activities, including ß-glucosidase (ß-GC), polyphenol oxidase (PPO), catalase (CAT), N-acetyl-β-D-glucosaminidase (NAG), leucine aminopeptidase (LAP), were notably affected. The altered community structure composition, reducing relative abundance Proteobacteria, Firmicutes, Actinobacteria, Planctomycetota time. These findings highlight impact on rhizosphere bacteria, providing insights for improved management fertilization strategies systems.
