| 摘 要： | 以鸡粪与牛粪两种禽畜粪便为原料,通过不同比例混合堆肥,重点研究了堆肥过程中,3种不同比例的堆体碳氮比(C/N)变化。结果表明,3种比例的混合堆体,经过49天的高温堆肥发酵,鸡粪︰牛粪为1:0.5比例的堆肥处理,其发酵周期最短,仅用30天即可腐熟。3种比例的堆肥处理,总碳含量和总氮含量均呈下降趋势,且总碳含量下降速度大于总氮含量。C/N变化为总体上呈现出缓慢下降趋势。3种比例的堆肥处理,鸡粪:牛粪为1:0.5的处理发酵效果较好。

| Abstract: | This article analyses the composting which is made up by the poultry dung and cow manure.The point is a carbon-nitrogen ratio （C/N） variation of the three kinds of composting.The composting lasted 49 days.The fermentation period of 1： 0.5 poultry-cow ratio is 30 days.The result reveals that both of total carbon （TC） and total nitrogen （TN） decreased all the time,and TC was decreasing faster than TN.The carbon-nitrogen ratio decreased slowly.When the three kinds of composting finished,the best one was the poultry-cow ratio is 1：0.5. |
