摘 要:介绍了育肥牛舍内的环境要求,如空气温度、湿度、气流速度、光照等诸参数的最佳范围值。探讨了我国北方封闭牛舍内,为了满足冬季育肥牛饲养要求而采用的温热环境控制方法和具体设施。通过在最冷的月份对太阳能供暖舍内的各环境参数的监测、与基本要求对比得出结论:封闭舍内采用空气式太阳能供暖,用于冬季育肥牛饲养是完全可行的,经济效益较高。The environmental requirements of fatten cowshed was introduced first, such as air temperature, humidity, airflow velocity and illuminance. Measures of warm environment control, to meet the need of raising fatten oxen in closed cowshed in winter of north China were researched. In winter of north China, main environment control facilities for heat preservation and raising temperature is applying pneumatic solar heating system. Through monitoring the environmental parameters of the solar heating cowshed in the coldest months, it is concluded that applying pneumatic solar heating system with humidity discharging to the closed cowshed for raising fatten oxen in cold north China is completely feasible, and the economic benefit is obvious, so this kind of cowshed will have a bright prospects for spreading.
