As the main organic waste after the cultivation of edible fungi, the resource utilization of mushroom residue is of great significance to the sustainable development of agriculture. Dissolved organic matter (DOM) is the key active component in the decomposition process of mushroom residue, and the dynamic changes of its content and structure evolution directly affect the environmental effect and fertility release of mushroom residue after returning to the field. At present, the research on the evolution law of DOM system at different decomposition stages of mushroom residue is not clear. Especially, the quantitative analysis on the continuous changes of key physical and chemical properties such as DOM aromaticity, molecular weight and humification degree is insufficient, which limits the efficient resource utilization of mushroom residue. Therefore, this study took mushroom residue as the research object, and aiming to reveal its dynamic evolution law by monitoring the changing trend of DOC content, aromaticity, molecular weight and humification degree of DOM in mushroom residue at different decomposition stages (5th, 15th, 30th and 60th days). In this paper, the characteristic spectral parameters of DOM in mushroom residue were systematically measured and analyzed by UV-Vis absorption spectroscopy, including SUVA254, SUVA260, SUVA280, A250/A365, A300/A400, α355, and spectral slope (SR), and the response order of DOM structure was further analyzed by combining with two-dimensional correlation spectrum (2D-COS). The results showed that the DOC content decreased significantly with the extension of the decomposition period, and decreased by 71.05% on the 60th day compared with the 5th day, indicating that the easily degradable organic carbon components in the mushroom residue were preferentially utilized by microorganisms. SUVA254 and SUVA260 decreased at first and then increased, while SUVA280 increased at first and then decreased, indicating that the aromatic components with simple structure in DOM were preferentially decomposed by microorganisms. A250/A365 and A300/A400 gradually decreased during the decomposition process, reflecting the increase of DOM molecular weight and humification degree. α355 decreased significantly, and the SR value was always less than 1, indicating that the DOM of mushroom residue was dominated by external input. 2D-COS analysis showed that the aromatic component (200 nm) was the most sensitive to the decomposition process. To sum up, this study revealed the regular phenomenon that DOM structure tends to be complex and stable in the decomposition process of mushroom residue, which would provide theoretical support for soil carbon sequestration and mushroom residue resource utilization. In the future, with the help of three-dimensional fluorescence and high-resolution mass spectrometry, the composition and transformation path of DOM in mushroom residue could be deeply analyzed, and the correlation analysis between DOM and microbial community function could be strengthened to fully reveal the driving mechanism and long-term ecological effect of DOM transformation of mushroom residue.

菌渣作为食用菌栽培后的主要有机废弃物,其资源化利用对农业可持续发展具有重要意义。溶解性有机质(DOM)是菌渣分解过程中的关键活性组分,其含量与结构演变的动态变化直接影响菌渣还田后的环境效应与肥力释放。目前针对菌渣不同分解期DOM系统演变规律的研究尚不明确,尤其是在DOM芳香性、分子量、腐殖化程度等关键理化性质连续变化方面的定量解析不足,限制了菌渣的资源化高效利用。因此,本研究以菌渣为研究对象,通过监测菌渣DOM在不同分解期(第5、15、30、60天)的溶解性有机碳(DOC)含量、芳香性、分子量和腐殖化程度的变化趋势,旨在揭示其动态演变规律。研究采用紫外-可见吸收光谱技术,对菌渣DOM的特征光谱参数进行系统测定分析,具体参数包括SUVA254、SUVA260、SUVA280A250/A365A300/A400α355和光谱斜率(SR),并结合二维相关光谱(2D-COS)进一步解析DOM结构的响应顺序。结果表明:随着菌渣分解期的延长,DOC含量呈显著下降的趋势,第60天较第5天降低71.05%,说明菌渣中易降解有机碳组分被微生物优先利用;SUVA254和SUVA260呈先降后升的趋势,而SUVA280先升后降,表明DOM中结构简单的小分子芳香性成分优先被微生物分解;A250/A365A300/A400在分解过程中逐渐下降,表明DOM分子量和腐殖化程度的提高;而α355显著降低,SR值始终小于1,说明菌渣DOM以外源输入为主导;同时2D-COS分析显示,芳香族组分(200 nm)对分解过程响应最敏感。综上,本研究揭示了菌渣分解过程中DOM结构趋于复杂且稳定的规律,研究结论为土壤碳固存和菌渣资源化利用提供了理论支撑。未来研究可借助三维荧光和高分辨质谱等技术,深入解析菌渣DOM的组成与转化路径,并加强其与微生物群落功能的关联分析,以全面揭示菌渣DOM转化的驱动机制与长期生态效应。

菌渣作为食用菌栽培后的主要有机废弃物,其资源化利用对农业可持续发展具有重要意义。溶解性有机质(DOM)是菌渣分解过程中的关键活性组分,其含量与结构演变的动态变化直接影响菌渣还田后的环境效应与肥力释放。目前针对菌渣不同分解期DOM系统演变规律的研究尚不明确,尤其是在DOM芳香性、分子量、腐殖化程度等关键理化性质连续变化方面的定量解析不足,限制了菌渣的资源化高效利用。因此,本研究以菌渣为研究对象,通过监测菌渣DOM在不同分解期(第5、15、30、60天)的溶解性有机碳(DOC)含量、芳香性、分子量和腐殖化程度的变化趋势,旨在揭示其动态演变规律。研究采用紫外-可见吸收光谱技术,对菌渣DOM的特征光谱参数进行系统测定分析,具体参数包括SUVA254、SUVA260、SUVA280A250/A365A300/A400α355和光谱斜率(SR),并结合二维相关光谱(2D-COS)进一步解析DOM结构的响应顺序。结果表明:随着菌渣分解期的延长,DOC含量呈显著下降的趋势,第60天较第5天降低71.05%,说明菌渣中易降解有机碳组分被微生物优先利用;SUVA254和SUVA260呈先降后升的趋势,而SUVA280先升后降,表明DOM中结构简单的小分子芳香性成分优先被微生物分解;A250/A365A300/A400在分解过程中逐渐下降,表明DOM分子量和腐殖化程度的提高;而α355显著降低,SR值始终小于1,说明菌渣DOM以外源输入为主导;同时2D-COS分析显示,芳香族组分(200 nm)对分解过程响应最敏感。综上,本研究揭示了菌渣分解过程中DOM结构趋于复杂且稳定的规律,研究结论为土壤碳固存和菌渣资源化利用提供了理论支撑。未来研究可借助三维荧光和高分辨质谱等技术,深入解析菌渣DOM的组成与转化路径,并加强其与微生物群落功能的关联分析,以全面揭示菌渣DOM转化的驱动机制与长期生态效应。

As the main organic waste after the cultivation of edible fungi, the resource utilization of mushroom residue is of great significance to the sustainable development of agriculture. Dissolved organic matter (DOM) is the key active component in the decomposition process of mushroom residue, and the dynamic changes of its content and structure evolution directly affect the environmental effect and fertility release of mushroom residue after returning to the field. At present, the research on the evolution law of DOM system at different decomposition stages of mushroom residue is not clear. Especially, the quantitative analysis on the continuous changes of key physical and chemical properties such as DOM aromaticity, molecular weight and humification degree is insufficient, which limits the efficient resource utilization of mushroom residue. Therefore, this study took mushroom residue as the research object, and aiming to reveal its dynamic evolution law by monitoring the changing trend of DOC content, aromaticity, molecular weight and humification degree of DOM in mushroom residue at different decomposition stages (5th, 15th, 30th and 60th days). In this paper, the characteristic spectral parameters of DOM in mushroom residue were systematically measured and analyzed by UV-Vis absorption spectroscopy, including SUVA254, SUVA260, SUVA280, A250/A365, A300/A400, α355, and spectral slope (SR), and the response order of DOM structure was further analyzed by combining with two-dimensional correlation spectrum (2D-COS). The results showed that the DOC content decreased significantly with the extension of the decomposition period, and decreased by 71.05% on the 60th day compared with the 5th day, indicating that the easily degradable organic carbon components in the mushroom residue were preferentially utilized by microorganisms. SUVA254 and SUVA260 decreased at first and then increased, while SUVA280 increased at first and then decreased, indicating that the aromatic components with simple structure in DOM were preferentially decomposed by microorganisms. A250/A365 and A300/A400 gradually decreased during the decomposition process, reflecting the increase of DOM molecular weight and humification degree. α355 decreased significantly, and the SR value was always less than 1, indicating that the DOM of mushroom residue was dominated by external input. 2D-COS analysis showed that the aromatic component (200 nm) was the most sensitive to the decomposition process. To sum up, this study revealed the regular phenomenon that DOM structure tends to be complex and stable in the decomposition process of mushroom residue, which would provide theoretical support for soil carbon sequestration and mushroom residue resource utilization. In the future, with the help of three-dimensional fluorescence and high-resolution mass spectrometry, the composition and transformation path of DOM in mushroom residue could be deeply analyzed, and the correlation analysis between DOM and microbial community function could be strengthened to fully reveal the driving mechanism and long-term ecological effect of DOM transformation of mushroom residue.
