摘　　要：为促进发酵床陈化垫料的循环化利用,以陈化垫料为原料,进行了堆肥腐解试验,探讨各种指标在堆肥进程中的变化趋势。结果表明:两试验组在堆置过程先后经历了升温期、高温期、降温期、腐熟期,温度变化趋势基本一致(P>0.05);pH均维持在7.5~8.5之间,水分不断降低(P>0.05);两试验组堆肥发芽指数保持上升趋势,堆肥至20d时,GI都大于80%(P>0.05);堆肥结束时,有机质、总养分、大肠杆菌(MPN)数、蛔虫卵死亡率及重金属指标均达国家有机肥NY 525-2012标准要求。研究结果显示,陈化垫料经高温堆肥后,产品能达到有机肥的要求。In order to promote the recycling utilization of waste litters,the composting experiment was conducted using the aging litter as materials.The variation of indicators in the process of composting were analyzed.Research results showed that two treatments in the stacking process has gone through the temperature-rising period,high temperature period,cooling period,maturity period（P〉0.05）;pH was maintained at 7.5~8.0（P〉0.05）;water continued to reduce;during the composting,germination index maintained an upward trend,and seed germination rate was greater than 80%（P〉0.05）;At the end of composting,the chemical and biological indexes,such as organic matter content,total nutrient,E.coli,the killing rate of ascarid eggs and the content of heavy metals were analyzed.The results showed that all these indexes met the national standards of organic fertilizer（NY 525-2012）.The results showed that composting products achieved the standards for organic fertilizer in China after the completion of the compost.
