Abstract
En 中文
• Reducing nitrogen by 30% plus mixed legume green manure (common vetch & hairy vetch) enhances topsoil carbon, nitrogen availability, and urease activity. • This integrated strategy reshapes the soil microbial community, enriching key phyla (e.g., Proteobacteria) and increasing network complexity. • Improved soil quality index (SQI) and microbial network structure jointly drive the increase in wheat grain yield.
