摘　　要：用静态箱-气相色谱法对两种不同堆放方式的奶牛粪便（自然堆放和覆盖玉米秸秆）在4个不同时段的温室气体排放速率进行了观测,结果表明：各个时段两种处理的温室气体排放速率变化趋势基本一致,但各个时段的排放速率有明显差异.两种处理温室气体的排放速率与牛粪温度相关极显著.覆盖玉米秸秆会减少CO2、N2O的排放,而且第3时段（2006年5月14日～6月14日）CO2的排放速率和第4时段（2006年8月2日～8月30日）N2O的排放速率与自然堆放的均差异显著;不同时段覆盖对CH4的排放影响不同,第4时段覆盖处理的CH4排放速率上升,并且与自然堆放的差异显著;其他时段两种处理温室气体的排放速率无显著差异.Two treatments（natural storage and cornstalk cover） and three repetitions were applied to pile dairy The emission of greenhouse gases （GHGs） from different treatments of stored dairy manure were observed by using the static chamber-GC theory with manual method in four periods. The emissions of GHGs between two treatments have the same variations in each period, but the emission is disparate in four periods. The emission of GHGs from treatment of natural pile was significantly correlated with manure temperature. The emission of CO2 and N20 decreased from the stored dairy manure with cornstalk cover. The emission of CO2 in the third period（2006-05-14～2006-06-14） and the emission of N20 in the fourth period（2006-08-02～2006-08-30） are significantly different, but the influence on the emission of CH4 is different in different periods, and CH4 emission with cornstalk cover increased, and was significantly different. The emission of greenhouse gases in the other period is not significantly different.
