摘要

摘要: 为探明堆肥过程中氨基酸（AA）浓度与腐植酸（HAs）形成的关系，分别以杂草（LW）、鸡粪（CM）、枯枝（GW）、蔬菜（CW）和秸秆（CS）为研究对象，研究其堆肥过程中AA及HAs的动态变化规律及二者的响应关系。结果表明：堆肥过程中AA浓度整体呈下降趋势，其中LW、CS中的AA浓度降低量（90.7%和80.9%）明显高于CM（67.4%）、GW（51.3%）和CW（50.1%）；而在堆肥过程中HAs浓度逐渐升高，其中LW中的HAs浓度增加量最大（66.8%），其次为CW（38.9%）、CS（43.9%）和CM（33.6%），而GW最小，仅为3.5%。Pearson相关性分析表明：堆肥过程中LW、CW和CS中的AA与HAs浓度之间呈显著负相关（P<0.05），说明纤维素类物料的AA对HAs形成有明显的促进作用。

Abstract: The dynamic of amino acids (AA) concentration and the influence on the formation of humic acids (HAs) were investigated during composting of cabbage waste (CW), lawn waste (LW), chicken manure (CM), garden waste (GW) and corn straw (CS). The results showed that AAs concentration was decreased during composting process. The decrease in LW (90.7%) and CS (80.9%) was more than CM (67.4%), GW(51.3%) and CW(50.1%). During the composting process, the HAs concentration was gradually increased. The increment of HAs concentration in LW (66.8%) was higher than CW (38.9%), CS(43.9%) and CM(33.6%), while GW was only 4.6%. The significantly inverse correlations have been obtained between AA and HAs concentration during LW, CW and CS composting, suggesting that AA derived from the cellulose materials composting can observably promote the formation of HAs.
