The intelligent monitoring system,dust sampler and oxygen detector were used in the experiment to measure the environment quality parameters such as temperature,relative humidity,air velocity,light intensity,carbon dioxide concentration,dust concentration and oxygen content at different points in an enclosed layer house with six overlap tiers cages in order to provide preference for environment quality of layer production.The results showed that the environmental quality at different measuring points were different.During the course of experiment,the temperature varied from 19.8℃ to 31.4℃ and the average temperature was 26.5 ℃.The relative humidity and air velocity were 86.31％ and 1.67 m/s,respectively.The concentrations of carbon dioxide,ammonia,dust and oxygen content were 653.57 mg/m3,0.38 mg/m3,3.06 mg/m3 and 20.75％,respectively.The temperature,air velocity,the concentration of carbon dioxide,ammonia and dust became greater along with the distance from the damp curtain to fan side,however,the relative humidity showed the trend of decreasing.The temperature,relative humidity,the concentration of carbon dioxide and dust concentration increased gradually with the tiers cages increased,however oxygen content decreased.The temperature showed significantly negative correlation with relative humidity.There was significantly positive correlation between temperature and carbon dioxide concentration,air velocity and oxygen content.The relative humidity and concentrations of carbon dioxide,air velocity,and oxygen content were significantly negative correlated.%使用环境智能监控系统、粉尘采样器和测氧仪对六层层叠式笼养鸡舍不同位置的夏季环境质量参数(温度、相对湿度、风速、光照强度、二氧化碳浓度、粉尘浓度和氧气含量等)进行了测定与分析,以期为蛋鸡层叠式笼养鸡舍环境控制提供参考依据.结果表明,鸡舍内不同测定点的环境质量之间存在差异.试验期间鸡舍内温度为19.8-31.4℃,平均温度为26.5℃;平均相对湿度和风速分别为86.31％和1.67 m/s;鸡舍空气中二氧化碳浓度、氨气浓度、粉尘浓度和氧气含量分别为653.57 mg/m3、0.38 mg/m3、3.06 mg/m3和20.75％.从鸡舍湿帘端到风机端温度、风速、二氧化碳浓度、氨气浓度和粉尘浓度呈逐渐增大的趋势,相对湿度呈递减趋势.随着笼层的增高,温度、相对湿度、二氧化碳浓度和粉尘浓度呈逐渐增大的趋势,氧气含量逐渐降低.温度与相对湿度呈显著负相关,温度与二氧化碳浓度、风速、氧气含量呈显著正相关,相对湿度与二氧化碳浓度、风速和氧气含量呈极显著负相关.
