Abstract
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.
