采用多种光谱方法研究了牛粪堆肥过程中水可提取有机物(WEOM)的变化规律。以光谱表征结果为基础，进行了多元统计分析，探讨了有机质转化相关参数之间的相关性。结果表明，堆肥过程降解了木质素、脂肪族化合物、醇类物质和类蛋白质物质，增加了可水提芳香族化合物和类腐殖质物质的含量，提高了牛粪的腐殖化程度。降解过程主要发生在堆肥的前几天，而富里酸和腐殖质类物质的形成发生在堆肥的后期。从WEOM分析得到的光谱参数分为两类：一类描述了分解状态。另一种反映了堆肥的稳定和成熟。(C)2012爱思唯尔B.V.保留所有权利。
Various spectroscopic approaches were used to characterize the evolution of water-extractable organic matter (WEOM) during cattle manure composting. Using the results of spectroscopic characterization as bases, multivariate statistical analysis was performed to investigate the correlation among the different parameters related to organic matter transformation. The results show that the composting process degraded lignin, aliphatics, alcohols, and protein-like materials, and increased the amount of water-extractable aromatic compounds and humic-like materials, as well as the humification degree of cattle manure. The degradation process primarily occurred during the first few days of composting, whereas the formation of fulvic- and humic-like substances took place during the later stages. The spectroscopic parameters obtained from the WEOM analysis were divided into two groups: one describes the state of decomposition. and the other reflects the stabilization and maturation of the compost.
