摘要
以猪粪和米糠为原料进行高温好氧堆肥,研究堆肥C/N比值对猪粪堆肥腐熟的影响。结果表明,C/N比值对堆肥的腐熟有明显的影响,C/N比值为28的处理其表征堆肥腐熟的各项指标(GI、NH4+-N/NO3-N比值和T值)均好于C/N比值为18、35和40的处理,说明猪粪高温好氧堆肥适宜的C/N比值为28。
A compost experiment using swine manure and rice bran was conducted to study the initial C/N ratio on maturity of composting.The results showed that the compost at initial C/N ratio of 28 had higher GI,Tvalue and lower NH4^＋-N/NO3^--N ratio than that of initial C/N ratio of 18,35,40. For lack of available nitrogen or available carbon in the compost at low C/N ratio or at high C/N ratio might contribute to restrain microorganism growth and metabolism. The optimum initial C/N ratio for pig manure composting was 28.
