摘要
以厨余垃圾和玉米秸秆作为堆肥原料,采用好氧堆肥的方法,探讨了不同C/N比对堆肥腐熟度的影响。结果表明:从温度、pH、电导率(EC)、腐植酸光学特性(E4/E6)、固相C/N和发芽率指数(GI)来看,只有C/N为21(T4)的处理没有达到无害化和腐熟的要求,其余3个处理均达到腐熟;建议采用C/N为17的方案,厨余垃圾和秸秆按照湿基质量9∶1的比例进行堆肥;如果秸秆资源比较丰富,可采用C/N为19的方案,此时厨余垃圾和秸秆湿基比例为5.7∶1。
Bascd on aerobic composling,thc impaet except of composting with different C/N ratio on maturity was studied in kitchen waste and corn straw. The results showed that, except the treatment of C/N ratio at 21 （T4） , all compost products met with national sanitation standard and reached maturity according to temperature, pH, electrical conductivity（EC） , E4/E6, C/N ratio and germination index（GI）. Therefore, it is recommended that C/N ratio atl7 is better for kitchen waste composting,the kitchen waste and corn straw basis on the wet weight ratio of 9：1 for composting; if corn straw is abundant, C/N ratio at 19 is better, kitchen waste in the composting of corn straw accounts for 15% in wet weight is suitable.
