摘要: 在规模化猪场内选择垫料育肥猪舍作为试验舍,以传统水泥地面育肥猪舍作为对照,利用多气体分析仪对试验舍和对照舍春夏两个育肥季节的NH3、CO2、CH4和N2O含量进行了连续3d的监测。结果表明:试验舍NH3、CO2、CH4和N2O的平均含量分别只有对照舍的40%、70%和77%,存在显著性差异(P<0.05);夏季由于温度高,垫料易于厌氧发酵,加大了CH4排放,试验舍CH4平均含量高于对照舍,但两者之间无显著差异(P=0.089),春季试验舍的CH4平均含量低于对照舍,两者之间差异显著(P<0.05);试验舍中NH3含量变化在春季和夏季无显著差异(P=0.072),CO2、CH4和N2O则存在显著性差异(P<0.05),夏季试验舍CO2含量低于春季,但NH3、CH4和N2O含量高于春季试验舍。说明垫料型猪舍能够改善舍内环境,减少有害气体排放。

Abstract: To investigate ammonia and greenhouse gas concentration condition in swine barn,a hoop structure barn as experiment barn and typical swine barn with brickconcrete floor as control were chose at a confined swine farm in Beijing,gases concentration were measured for 3 consecutive days during spring and summer seasons using INNOVA 1312 multigas monitor. The results showed that the average NH3、CO 2、  N 2 O concentration in experiment barn was by 40%,70%,77%,respectively,compared with control barn (P<0.05).The average  CH4  concentration in hoop structure was higher than that in the control barn in summer,but lower in spring.The concentrations of CH4、CO 2、  N 2 O had significant different(P<005) between summer and spring season in the hoop structure,but NH3 had no significant different,the CO 2 concentration was lower in summer,NH3、CH 4、  N 2 Oconcentration was higher in summer than that in spring. The hoop structure barn could improve indoor environment and mitigate gases emission.
