不同堆高奶牛粪便长期堆积过程中温室气体和氨排放特点
Greenhouse gas and ammonia emissions from different piling heights in long-term stacks of dairy manure
摘要
Abstract
The present study aimed to analyze the effects of piling height on greenhouse gas and NH3emissions during 41 weeks stacking of dairy manure, and the effects on global warming potential(GWP)and particulate matter 2.5(PM2.5)were also investigated. Emissions of CH4and N2O were measured by the static chamber-gas chromatography technique and NH3was measured by the venting method.The re-sults showed that CH4and N2O cumulative emissions from manure in stack heights of 50 cm were significantly higher than that of 25 cm. However,the opposite trend was shown for NH3emission.Methane was the largest contributor to GWP,accounting for 61.41%~63.97% of the total value,N2O being the second largest contributor at 32.71%~33.70%,and NH3contributing the least,accounting for only 2.33%~5.88%.GWP increased as stacking height increased from 25 cm to 50 cm,while PM2.5forming potential decreased significantly.The present study suggested that the choice of manure management measures should be taken into consideration for multiple environmental problems.关键词
