| 摘要: |
| 研究了以鸡粪与牛粪为代表的畜禽废弃物,在强制通风静态堆肥设备中堆肥化时,几种化学参数的变化趋势及作为腐熟指标的可行性。结果表明:固相C/N,NH4+-N与WSC含量可作为畜禽废弃物堆肥的优选指标; R, E4/E6,有机质中腐殖酸类物质(HS,HA,FA)含量与CEC可作为该类堆肥的一般性指标;NO3--N含量用作参考。 |

| Abstract: |
| The paper researches on the trendency changes of several chemical parameters of poultry wastes in caged chicken manure and cattle manure during composting in
aerated static pile vessel, and evaluated these chemical parameters feasibility as maturity
indices.The trial indicates that NH4+-N percentage,WSC percentage and solid-state C/N are the priorly sellected maturity indices for poultrywaste composts, that HS percentage,HA percentage,FA percentage, humification ratio (R) and E4/E6,CEC are considerated as commonindices for the composts, and that NO3--N percentage is regarded as
reference index. |
