摘要：

选用鸡粪与小麦秸秆为堆肥原料进行高温好氧堆肥实验,研究鸡粪高温好氧堆肥过程中堆体温度、pH值、碳氮比等理化指标的变化,为农业废弃物快速资源化利用提供科学依据和技术指导。结果表明：鸡粪与小麦秸秆在C/N=30时达到的温度最高为60℃，高温持续时间为11d,堆肥过程中pH值是先上升后下降的过程。堆肥结束时C/N为16.4，NH4+-N含量比最高时降低了74.2%。HR比开始增加了58.8%，胡敏酸相对于最低点升高了107%，富里酸与堆肥前相比降低47.1%。

Abstract:

In the research, chicken manure and wheat straw used as material, high-temperature aerobic composting were carried on. Changes of physical-chemical index of ambient temperature、pH、C/N were studied to provide a scientific basis and technology guideness for rapid ultilizating agricultural waste resources.Results showed: ambient reached the highest temperature 60℃when C/N=30,the high temperature can sustained 11d,pH increased then decreased during the composting. At the end of composting,C/N=16.4, the content of NH4+-N reduced 74.2% comparing with the highest,HR increased 58.8% and humic acid increased 107% comparing with the lowest, fulvic acid decreased 47.1% comparing with the pre-compostion.
