过磷酸钙在猪粪堆肥过程中的保氮效果研究
Nitrogen Conservation of Calcium Superphosphate in Swine Manure Compost
摘要
Abstract
[Objective] The research was conducted to reduce the nitrogen loss of co-composting of swine manure and rice bran. [ Method ] Static forced-aeration composting reactors were used to study the effects of calcium superphosphate on reducing nitrogen loss of co-composting of swine manure and rice bran. [ Result ] Calcium superphosphate could increase compost temperature, reduce Ph obviously, increase the contents of soluble NH4+ -N,reduce the amounts of NH3 emission and postpone the maximum period of NH3 emission. Compared to the control,1% ,2% and 3% of calcium superphosphate could reduce nitrogen loss by 33. 56% ,49. 18% and 52. 88% respectively. Calcium superphosphate addition could also increase phosphorus contents of compost. [Conclusion] The optimized ratio of calcium superphosphate usage for composting was 2% -3%.关键词
