摘要： Straw returning is key measure for carbon sequestration and soil enrichment, yet it is constrained by regional decomposition rates. Enhancing the decomposition of resistant straw in cold climates is a critical issue in soil fertilization. Previous studies have shown that applying inorganic nitrogen fertilizer can promote straw decomposition by adjusting the carbon-nitrogen ratio (C/N), but the dynamic effects of different organic nitrogen forms on straw decomposition and its mechanism remain uncertain-a research gap pivotal for optimizing fertilization strategies. This study employs incubation experiments to examine the decomposition dynamics and nutrient release of maize straw with varying nitrogen forms and its microbial mechanisms. We found that the effect of ammonia on straw decomposition was different, and the effect of glutamic acid was better than that of alanine. It regulates the soil C/N alter the richness, diversity and correlation of the dominant soil bacteria (Lysobacter and Sphingomonas), accelerating the straw decomposition (47.2 %) and the nitrogen nutrients release (81.3 %). This result suggests that amino acid substitution for nitrogen can promote straw decomposition, but not for all amino acids. The selection of amino acids with promoting effect can effectively solve the problem of straw decomposition resistance.This practice improves soil quality and prevent degradation in regions with slow decomposition.
