In this study, we analyzed 108 samples evaluated root traits, growth characteristics, soil enzyme activities, metabolites, chemical properties to identify primary determinants community assembly. Across 36 samples, obtained 969,634 high-quality sequences, clustering into 6,284 ASVs predominantly classified Proteobacteria (57.99%), Actinobacteria (30%), Bacteroidetes (5.13%). Our findings revealed that metabolites accounted more variance in compared (ANOVA, F = 1.53, p 0.04), or traits 1.04, 0.001). Seven small molecule including glycerol, sorbitol, phytol, alpha-ketoglutaric acid, were significantly correlated with βNTI, underscoring their role as critical genus Rhizobium , associated βNTI (R 0.25, 0.009), emerged keystone taxon structure. Soil culture experiments further validated can modulate ST treatment, enriched produced 1,032,205 sequences exhibited significant shifts (Adonis, 0.001, R 0.463), showing higher abundance control (CK). Variable selection (βNTI >2) drove phylogenetic turnover ST, while stochastic processes (|βNTI| < 2) dominated CK.

Soil samples were collected before planting the early rice, after harvesting late rice. physicochemical properties, yield, (total nitrogen, phosphorus, potassium contents) determined. Variation of microbiota also determined by high-throughput sequencing. We found that content significantly improved during process (P < 0.05), while phosphorus displayed significant variation under 0.05). Notably, was higher than 0.001) treatment. Furthermore, positively correlated available indicating promoted uptake.
