【摘要】 大型牛舍内空气环境是影响奶牛生长状况的重要因素,合理的温湿度范围是减少疾病、保证奶牛正常生产的必备条件。文章以香坊农场奶牛场为试验基地,绘制出室外温度为-20℃时牛舍内不同温度所需通风量随相对湿度变化曲线图;得出牛舍温度在1-10℃,湿度RH为70%-90%时其通风范围为2.64-5.5m3·s-1,对冬季牛舍温度、湿度控制具有指导意义。更多还原

【Abstract】 The air environment in cow house is very important influencing factor for cow’s growth, the reasonable temperature and humidity are necessary to reduce disease and ensure the normal product of cow. Taken the Xiangfang Dairy Farm as research base, through experiment and calculation, the figure of circulating air quantity with various temperatures and humidity was done. The result showed that when temperature in cow house was kept 1-10 ℃ with humidity RH 20%-90%, the circulating air quantity should be 2.64-5.5 m3·s-1. The result is very valuable for controlling temperature and humidity in cow house during winter.更多还原
