中文摘要: 采用静态箱-气相色谱法研究了自然状态下牛粪(C) 、牛粪+秸秆(CSt) 、牛粪+土(CSo) 、牛粪+秸秆+土(CStSo) 4种堆肥模式对温室气体排放的影响,以期为温室气体减排和堆肥模式优化提供参考。结果表明:堆肥期间堆温和温室内气温随时间推进均呈升降升的趋势,同一观测时间点气温高于堆温,总体上CSt、CStSo处理的堆温略高于C、CSo处理,表明加入秸秆具有提高堆温的效果。随时间推进,C处理的CO_2、CH_4和N_2O排放通量总体均呈增加的趋势,第6 ~ 7周排放通量较大; CSt、CSo、CStSo处理的3种温室气体排放通量总体均呈先升后降的趋势,CO_2和CH_4排放通量最大值总体出现在第2周,N_2O排放通量在第5 ~ 6周时较大。CO_2平均排放通量表现为CSt >CStSo >CSo >C,除C处理与CSo处理无显著差异外,其他处理间差异显著; CH_4平均排放通量表现为C >CSt >CStSo >CSo,C处理与CSt、CSo、CStSo处理之间及CSt、CSo处理之间差异显著; N_2O平均排放通量表现为CSo >CSt >CStSo >C,CSo处理与C处理差异显著。CSt、CSo、CStSo处理的全球增温潜势(GWP)分别是C处理的3.25、2.61、2.59倍,主要是由于CSt、CSo、CStSo处理的CO_2和N_2O排放总量显著高于C处理,其对GWP的贡献率均高达97%以上。综合考虑广大农村堆料实际组分及温室气体减排,建议采用CStSo堆肥模式,但应适当增加牛粪和土的用量。
英文摘要: The effect of four composting treatments,such as cattle manure(C),cattle manure and straw (CSt),cattle manure and soil(CSo),cattle manure,straw and soil(CStSo) on greenhouse gases(GHGs) emission were studied by using the static chamber-gas chromatograph techniques,so as to provide a reference for GHGs emission reduction and composting model optimization. The results showed compost temperature and air temperature in greenhouse both took on rising-descending-rising trend during composting period. But the air temperature was higher than compost temperature at the same observation time. Overall, the compost temperature of CSt,CStSo treatments were higher than those of C,CSo treatments,indicating that adding wheat straw could increase the compost temperature. The emission flux of carbon dioxide (CO_2),methane(CH_4),and nitrous oxide(N_2O) under C treatment increased with the time going on, and the maximum value appeared between the sixth and seventh week. The trend of GHGs emission flux of CSt,CSo,and CStSo treatments first increased and then declined,the maximum emission flux of CO_2 and CH_4 appeared on the second week,the maximum emission flux of N_2O was observed during the fifth and sixth week. The order of average CO_2 emission flux was CSt >CStSo >CSo >C,among which all treatments were significantly different except C and CSo treatments. The order of average CH_4emission flux was C >CSt >CStSo >CSo,among which CSt,CSo,CStSo treatments were significantly different with C treatment, and CSt treatment was also significantly different with CSo treatment. The order of average N_2O emission flux was CSo >CSt >CStSo >C,among which C and CSo treatments were significantly different. The global warming potential(GWP) of CSt,CSo,and CStSo treatments were 3.25,2.61,and 2.59 times of C treatment respectively,which showed that cattle manure compost gave out the lowest amount of GHGs. Based on the GHGs emission amount and realistic compost constituent,CStSo treatment was recommended to apply after increasing the ratio of cattle manure and soil.
