摘要： 本文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，三种不同比例的堆体碳氮比（C/N）变化。结果表明，三种比例的混合堆体，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。三种比例的堆肥处理，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。三种比例的堆肥处理，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.
