摘　　要：试验旨在研究夏季半开放式蛋鸡舍内不同位置饮水温度、气温的变化情况。试验对夏季半开放式蛋鸡舍内不同位置环境温度和水线温度进行了监测。结果显示:①夏季半开放式鸡舍内温度波动较大,温差范围为2.7~5.5℃。②整栋鸡舍从西向东温度逐渐升高,从南到北温度逐渐降低,温度最低点位于西北侧,最高点在东南侧。③不同位置温差不同:三层中的下层温差最低,上层温差最高;西侧到东侧温差最大;整栋鸡舍中间位置中间高度温度适宜,温差小;饮水温度与气温显著相关。研究表明:采用湿帘-风机自动控温系统的有窗半开放式蛋鸡舍夏季舍内不同位置温差大,局部位置温度偏高,应加强降温处理和午后放水等措施降低舍内环境温度和饮水温度。This experiment aimed to study the changes of drinking water temperature and atmospheric temperature at different positions in semi-open layer house in summer. The environmental temperature and waterline temperature at different positions in semi-open layer house in summer were monitored. The results showed that: ① The temperature fluctuation in the semi-open house in summer was large, and the temperature difference ranged from 2.7 to 5.5 ℃.② The temperature of the whole chicken coop increased gradually from the west to the east, and decreased gradually from the south to the north. The lowest temperature was in the northwest, while the highest temperature was in the southeast. ③ The temperature difference at different positions was different. The bottom temperature difference was the lowest, the top temperature difference was the highest in three layers. The maximum temperature difference was from the west to the east. The middle height of the middle position of the whole layer house was suitable, with small temperature difference. Drinking water temperature was significantly correlated with the atmospheric temperature. The use of wet curtains-automatic temperature control system for fans had a large temperature difference between different positions in semi-open layer house in the summer. So the cooling treatment should be strengthened, or the water should be discharged in the afternoon to reduce the drinking water temperature.
