Abstract
En 中文
• A synergistic strategy of straw mulching with moderate N achieves high yield and low N₂O emissions. • This strategy shifts soil N dynamics from nitrate-dominated to ammonium-dominated by modulating key microbial functions. • The N₂O mitigation effect of straw mulching is N-rate dependent, clarifying previous contradictory findings.
