| 英文摘要 | A substantial amount of seaweed waste, rich in plant-stimulating properties, holds great potential for composting. However, without proper catalysts or additives, composting and humification are slow and inefficient, causing carbon and nitrogen losses. This study explores a novel approach to enhance composting efficacy by coupling phosphate with high-carbon ferromanganese particles (HCFMP). The results indicate that the phosphate-HCFMP coupling promotes humus precursor transformation, as evidenced by dynamic changes in reducing sugars, amino acids, and polyphenols. Additionally, ultraviolet characteristic parameters and Parallel Factor (PARAFAC) analysis show that the coupled treatment improves both the rate and degree of humification. By the end of composting, this treatment exhibited the highest HA/FA (4.38), with the HA/FA on day 21 surpassing other treatments on day 35. While the phosphate-only group achieved a relatively high degree of humification, the process was slower and accompanied by substantial NH3 volatilization. The HCFMP-only group reduced NH3 emissions, but the oxidative performance of HCFMP was enhanced under lower pH conditions, reducing organic matter participation in humus formation. Compared to phosphate alone, the coupled treatment reduced NH3 emissions by 48.6% and increased nitrate content by 12%. Further analysis suggests that the enhancement mechanisms may include: (1) phosphate stimulating humus precursor production; (2) HCFMP mainly acting as a catalyst under higher pH to promote precursor polymerization; and (3) HCFMP's acidic sites adsorbing NH3/NH4+ and facilitating nitrification. In conclusion, coupling HCFMP with phosphate enhances composting efficacy, and the resulting products, with plant-stimulating properties, offer a feasible solution for sustainable green agriculture development. |
