冬季层叠式笼养肉鸡舍温湿度分布规律研究

Study on Distribution Characteristics of Temperature and Humidity in Broiler House with Overlap Cages in Winter

为研究采用地暖供热、封闭式有窗、层叠式笼养肉鸡舍中温度、湿度的分布与变化规律及二者的相关性,采用分次多点测量法,对山西某公司养殖基地一栋上述鸡舍内的温度、湿度进行定量检测。结果表明:在冬季该类型鸡舍内的温度呈中间高两边低,由上往下逐渐递增的态势,其变化范围可控制在定温的±2℃内;舍内湿度呈两边高中间低,中层略高于上下层的态势,由于冬季外界湿度较低,其变化范围在±7%内;该环境下温湿度之间相关系数R2=-0.2887,二者间相关性非常弱。提示:在冬季该类型鸡舍内温湿度分布合理而且变化范围小,适宜肉鸡生长,但要注意通风小窗的调控。

To investigate the distribution rule and correlativity of temperature and relative humidity of enclosed broiler house with warm floor heating and overlap cages in winter, quantitative detection of temperature and relative humidity of broiler house in the breeding base of Shanxi Daxiang Farming Group was used. Analysis tool was SAS statistical software. The results showed that during winter,the temperature of broiler house becomed higher in mid than in other spaces and increasing downward, while its variation range was controlled at ±2℃. The humidity showed a trend of higher in both sides than in mid space with slightly higher intermediate,while its variation range was controlled at ±7% due to the humidity difference between inside and outside broiler house in winter. The weak correlativity was between temperature and relative humidity for R2=0.2887. During winter, the variation,the data distribution of temperature and relative humidity of above-mentioned broiler house was applicable,and the range was small,which meaned a suitable growth condition for the broilers,yet the adjustment of ventilation windows should be pay more attentions.
