| 摘 要： | 将猪粪与秸秆以7：1（质量比,以鲜重计）的比例,在自制的强制通风静态堆肥反应箱中进行高温堆肥试验,研究了堆肥过程中碳氮转化特征及其腐熟时间.同时,在堆制的23d中,根据堆温变化采样6次,分析了堆肥样品中各种氮素和碳素含量及其它性质的变化情况.结果表明：堆肥结束时,硝态氮含量增加了103.0%,铵态氮、有机氮、总氮含量分...

| Abstract: | An experiment was conducted to study the C and N dynamics and stabilization time of a swine manure-straw compost.Fresh swine manure and wheat straw were mixed at a 7:1 ratio and then composted in a self-built,static forced-air composting box (90 L).The outer wall of the box was insulated with 8cm plastic foam.Temperature was monitored every day and compost samples were taken 0,4,8,12,17,and 23 d after the start of the experiment.Ammonium (NH+4-N),nitrate (NO-3-N),organic N (Org-N),water-soluble organic C,or... |
