摘　　要：为了研究生物发酵床对育肥猪舍空气环境的影响,2010年1月10日至2010年12月10日在定西某猪舍进行气体采集测定试验,对利用生物发酵床技术（试验组）和普通水泥地面饲养（对照组）圈舍内氨气（NH3）和硫化氢（H2S）2种气体的季节浓度变化进行了研究.结果表明：生物发酵床技术组冬季猪舍环境温度显著高于普通水泥地面饲养组（P〈0.05）,分别为17.8~21.3℃和6.9~12.4℃;试验组猪舍内NH3平均浓度在各季节均低于对照组,夏季极显著低于对照组（P〈0.01）;试验组H2S浓度极显著低于对照组（P〈0.01）.据此认为,发酵床养猪降低了猪舍内NH3、H2S等有害气体的浓度,为猪的生长发育提供适宜的环境.A comparison on concentration changes of NH3 and H2S was made between fermenting bed pigpen and portland cement pigpen in Dingxi in 2010,in order to evaluate the effect of fermenting bed on pigpen environment.The results showed that fermenting bed pigpen had a higher temperature in winter（P0.05）,and a lower NH3 concentration in each season.Fermenting bed pigpen had a significant difference in NH3 concentration（P0.01） in the summer when compared with portland cement pigpen.Fermenting bed pigpen also had a lower H2S concentration（P0.01）.It is suggested that fermenting bed pigpen can supply a suitable environment for pigs by reducing concentration of NH3 and H2S in pigpen.
