ABSTRACT Intercropping with green manure is recognized as a sustainable and ecological agricultural practice that regulates soil microbial activity promotes plant growth. Despite its potential benefits, the impact of tea plants intercropping on organic plantations remains largely unexplored. This study primarily evaluated effects summer winter (TSR: soybean + ryegrass; TMR: mung bean radish; TSC: common vetch; TM: monoculture, consider control) community composition, quality, bacterial function in an plantation. Relative to TM, TMR improved physical structure by decreasing penetration resistance bulk density 30.4% 9.30% ( p < 0.05), thus creating conducive environment for growth activity.

Crop rotation systems profoundly influence soil phosphorus (P) dynamics through physicochemical and microbial interactions. The mechanisms regulating P availability under various rotational practices remain poorly understood. This five-year field experiment investigated the effects of four (WM: wheat–maize; WP: wheat–peanut; WS: wheat–soybean; MV: maize–hairy vetch) on fractions, phosphatase activities, P-cycling gene abundance, their interactions with properties. WM substantially reduced pH (6.29) while increasing labile fractions (Ca2-P) moderately (Al-P, Fe-P, Ca8-P), which was attributed to enhanced acid activity. WP elevated (8.13) but due calcium–P immobilization. MV stimulated cycling, exhibiting highest phoD (2.01 × 106 copies g−1) phnK (33,140 linked green manure-induced activation. Redundancy analysis identified pH, total nitrogen, stoichiometric ratios (C/N N/P) as key shared drivers enzymatic Partial least squares path modeling (PLS–PM) indicated that crop directly regulated modulation (r = −0.559 ***) C/N ratio 0.343 indirectly Lower (<10) across all regimes amplified carbon limitation in process transformation, indicating exogenous inputs appropriate stoichiometry should be optimized. results this study inform selection suitable patterns for sustainable agriculture.
