摘  要：
[目的]测定、评价鸡粪好氧堆肥腐熟度,为堆肥生产提供参考。[方法]采用自制的简易发酵罐,实验室模拟鸡粪便好氧堆肥发酵,测定堆肥不同时段具有实用意义的腐熟度和粪便无害化标准的各项指标,并对堆肥腐熟情况进行分析与评价。[结果]好氧堆肥温度最高达50～55℃以上并持续5～7 d,pH的变化范围为7.3～8.6,含水率基本维持在60%左右,有机质含量由最初的86.2%降至63.9%,C/N由最初的24.7降至堆肥12 d 20.0、0,种子发芽指数在堆肥第10天达80%以上,粪大肠菌值由0.001升至0.173,蛔虫卵的死亡率在第7天左右达95%以上。[结论]堆肥过程中的温度、pH、含水率、有机质含量、C/N、种子发芽指数、粪大肠菌值及蛔虫卵的死亡率等指标均达到鸡粪好氧堆肥腐熟度的要求,保证了堆肥的充分腐熟。

摘  要：
[Objective] Maturity during aerobic composting of chicken manure was determined and evaluated to provide reference for compost production.[Method] Determination of indicators with practical significance at different time of maturity and standard harmless manure was conducted under laboratory simulated fermentation of chicken manure compost by using homemade simple fermenter,and the maturity of the composting was analysed and evaluated.[Results] Aerobic composting reached the highest temperature 50-55 ℃ for 5 to 7 days.The range of pH was between 7.3 and 8.6.The moisture content was in the vicinity of about 60%.The content of organic matter was dropped from 86.2% to 63.9 %.The C/N decreased from the initial 24.7 to 20.0、0 in the twelfth day of the composting.Seed germination index was more than 80% in the tenth day of the composting.Coliform group value increased from 0.001 to 0.173.The mortality rate of ascaris eggs was more than 95% in the seventh day.[Conclusion] The indicators of the temperature in the composting process,pH,moisture content,organic matter content,C/N,seed germination index,coliform group value and ascaris eggs mortality had reached the requirements of the chicken aerobic composting and ensured the full maturity of the compost.
