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.
