摘　　要：采用封闭罐-气相色谱法对4种不同温度处理下奶牛粪便温室气体排放速率进行测定。结果表明,温度是影响奶牛粪便温室气体排放的主要因子,温度较低时奶牛粪便温室气体排放速率低,而且随着奶牛粪便处理温度升高而增大。在5、15、25和35℃4个处理中,奶牛粪便CO2排放速率两两之间差异显著;CH4排放速率除了5和15℃处理差异不显著之外,其他两两处理之间差异显著;35℃处理时N2O排放速率与其他温度的排放速率差异均显著,其他两两处理之间差异不显著。Fluxes of greenhouse gases emitted from cow manure in four different temperature treatments （5, 15, 25 and 35 ℃ ） were measured using closed-air-chamber-gas-chromatography to determine effect of temperature on the emission. Resutls show temperature is the main factor influencing the greenhouse gases emission from the manure. When the manure was low in temperature, greenhouse gases emission was less. The emission increased with the temperature. CO2 emission varied sharply with the temperature, and so did CH4 emission except for Treatments 5 and 15 ℃. In Treatment 35 ℃, N2O emission was significantly higher than the others, while it did not vary much between the others.
