摘要: 有机固体废弃物好氧堆肥是实现碳资源化利用的重要途径，其核心在于微生物驱动下有机碳向腐殖酸的转化。腐殖酸作为有机肥的核心活性组分，可有效改良土壤结构、提升土壤保水保肥能力，促进作物生长。然而，堆肥过程中矿化与腐殖化同步发生，碳流向的竞争直接影响最终腐殖酸积累量与堆肥品质。本文系统梳理了堆肥腐殖酸形成的物质转化路径与微生物驱动机制，旨在从物质转化与微生物代谢两个维度构建腐殖酸形成与碳流向竞争的理论框架，以期为农业有机废弃物堆肥品质提升与农田土壤培肥提供理论参考。
Abstract: Aerobic composting of organic solid waste is an important approach for carbon resource utilization, with its core lying in the microbial-driven conversion of organic carbon into humus. As the primary active component of organic fertilizer, humus can effectively improve soil structure, enhance soil water and nutrient retention capacity, and promote crop growth. However, mineralization and humification occur simultaneously during composting, and the competition for carbon flow directly affects the final humus accumulation and compost quality. This paper systematically reviews the material transformation pathways and microbial driving mechanisms of humus formation during composting, aiming to construct a theoretical framework for humus formation and carbon flow competition from the dimensions of material transformation and microbial metabolism, with the intention of providing theoretical references for improving the quality of agricultural organic waste compost and farmland soil fertility enhancement.
