摘　　要：为探讨不同局部供暖措施对保育猪局部热环境的影响及其在不同高度上的温湿度变化,对电地暖供暖、红外保温灯供暖和顶板电热板供暖三种局部供暖状况进行了对比分析。试验分析了三种局部供暖所在区域1.0 m高处的温湿度情况和每种局部供暖不同高度(地面、0.3 m、0.7 m和1.1 m)的温湿度变化情况。结果表明,在猪舍整体环境CO_(2)平均浓度5 804 mg/m^(2),NH_(3)平均浓度21 mg/m^(3)的条件下,电地暖、顶部电热板和红外保温灯所在区域1.0 m处的猪栏温度分别为13.1~16.8℃,14.3~16.9℃和13.7~18.2℃,湿度均为76.4%~98.7%。电地暖、顶部电热板和红外保温灯(中心位置)的地面温度分别为(28.0±0.3)℃、(25.8±0.6)℃和(26.8±0.5)℃,电地暖供暖地面温度显著高于顶部电热板(P<0.05)。仔猪活动范围(距地面0.3 m高度)的局部环境温度保温灯组(中心位置)(21.3±0.7)℃和顶部电热板组(20.7±0.3)℃显著高于电地暖组(18.4±0.4)℃(P<0.05),三种供暖组的仔猪活动区域(0.3 m)的湿度范围是65%~75%,与1.0 m供暖区域湿度水平相比,得到了有效改善。局部供暖可以在一定程度上改善猪只环境,其中,顶部电热板相比电地暖和红外保温灯供暖综合效果更好。In order to explore the effect of various local heating systems on local nursery environment,the thermal environment indexes of electric floor heating,infrared heating lamps and top radiant heating were monitored.This study analyzed the temperature and humidity of the test pens at the height of 1.0 m and the temperature and humidity of the three heating systems at different height(floor,0.3 m,0.7 m and 1.1 m).The test results showed that the overall house average concentration of CO_(2) and NH_(3) were 5804 mg/m^(3) and 21 mg/m^(3),respectively.The temperature of test pens with electric floor heating,top radiant heating and infrared heat lamps at the height of 1.0 m were 13.1~16.8℃,14.3~16.9℃and 13.7~18.2℃,respectively.The humidity was 76.4~98.7%.The local floor temperature of electric floor heating,top radiant heating and infrared heat lamps(central position)were(28.0±0.3)℃,(25.8±0.6)℃and(26.8±0.5)℃,respectively.There was significant difference(P<0.05)between the ground temperature of electric floor heating and top radiant heating.The local ambient temperature in the area of pig activities(0.3 m height from the ground)for the infrared heat lamps(center position)was(21.3±0.7)℃and the top radiant heating was(20.7±0.3)℃,which were significantly higher than the electric floor heating(18.4±0.4)℃(P<0.05).The local environmental relative humidity of the three kinds of heating measures ranged from 65%to 75%,and it has been effectively improved compared with the humidity levels at the height of 1.0 m.Local heating can improve the environment of pigs,among which,top radiant heating has better heating effect than electric floor heating and infrared heat lamps.
