| 英文摘要 | The growing demand for animal protein has led to increased cattle manure production, resulting in nutrient loss and greenhouse gas emissions. Rich in organic matter, cattle manure is a promising substrate for producing biochemical fulvic acid (BFA), offering sustainable benefits for agriculture and the environment. Although BFA has been extracted from various organic sources, systematic analysis of its extraction process, structural characteristics, and functional properties from cattle manure compost remains limited. In this study, BFA was extracted from cattle manure compost using a KOH-H2O2 oxidation system, and conditions were optimized via response surface methodology. The optimal extraction parameters were KOH concentration 0.8 mol/L, solid-toliquid ratio 1:10.2, reaction temperature 84 degrees C, reaction time 2.11 h, and H2O2 concentration 3.14 %, achieving a 17.83 % BFA yield. Compared to MFA, BFA has a higher O/C ratio, more diverse functional groups, and a lower molecular weight, indicating greater bioactivity and soil improvement potential. The BFA chemical formula was predicted as C75H112N7S4O49. Pot experiments and metagenomic sequencing showed that BFA significantly promotes rice seedling growth, increases rhizosphere microbial diversity, and enhances soil carbon metabolism. The innovation of this study lies in the comprehensive evaluation of BFA derived from cattle manure compost, providing a sustainable alternative to MFA and new insights into the structural and functional properties of BFA, as well as its positive impacts on plant growth and soil health. This study supports the high-value utilization of livestock waste and promotes BFA as an eco-friendly biofertilizer and soil conditioner in sustainable agriculture, contributing to sustainable agricultural development. |
