摘要
对大棚舍、有窗舍和开放舍三种类型猪舍冬、夏季五项环境指标的测定与分析，研究新型塑料大棚规模化养猪舍环境状况与特点。结果表明，新型塑料大棚规模化养猪舍内冬季空气温度为１１．３℃，相对湿度为７２．３％，气流速度为０．１９ｍ／ｓ，二氧化碳浓度１０００ｐｐｍ；夏季，空气温度２６．５℃，相对湿度为８０．２％，气流速度为０．７２ｍ／ｓ，二氧化碳浓度为６４０ｐｐｍ。大棚舍内环境冬、夏季均优于有窗舍，夏季与开放舍差异不明显。
In the present experiment, the characteristic of air environmental situation in new type plastic shed large house (shed) was studied by determining five indexs in and outside shed, closed with windows pig house (closed with windows), opened pighouse (opened) in winter and summer. The results showed that the air environmental situation in shed was followed: In winter, the air temperature was 11.3℃, relative humidity was 72.3%, speed of air movement was 0.19 m/s, concentration of CO 2 was 1000 ppm in shed; In summer, the temperature was 26.5℃, relative humidity was 80.2%, speed of air movement was 0.72 m/s, concentration of CO 2 was 640 ppm. The air environmental situation in shed was better than in closed with windows winter and summer, and better than in opened winter, but was no significant difference with it in opened summer.
