摘要
试验以猪粪和油菜秸秆为原料进行高温好氧堆肥,通过油菜秸秆的不同添加量调节堆肥中的C/N,利用不同C/N在堆肥过程中的温度、发芽指数、全氮、有机质和pH等参数,探讨了不同C/N对猪粪堆肥腐熟度的影响。结果表明:在添加生物菌剂、翻堆间隔天数和其他条件相同的情况下当C/N为22.72即猪鲜粪:油菜秸秆为6.5∶1(质量比)时的各项参数均达到较好的水平,取得较好的堆肥效果。
This experiment was conducted to use swine manure and rape straw as raw materials for high temperature compost,through adding different proportion rape straw in composting of adjustment of C/N,temperature,germination index,total nitrogen,organic and pH matter parameters used as compost maturity indicators.Results indicated that when the C/N was 22.72,the fresh swine manure： rape straw as 6.5∶1 with other equal conditions,the effect of composting was better.Each index reached the better level.
