开放式肉牛育肥舍冬季环境的测试与分析

The measurement and analysis of winter environment in open type beef barn

为了解开放式肉牛育肥舍冬季存在的环境问题并探讨问题产生的原因,试验对其冬季的主要温热环境和空气质量指标进行了测定与分析。结果表明:开放式肉牛育肥舍在黑龙江省冬季存在温度低、湿度大、空气质量差等问题,需要提高外围护结构的保温隔热能力、完善通风换气系统的设计并加强日常的环境管理。

To research the environmental problems existed in open type beef barn in winter and investigate the reasons of these problems, the main thermal environmental factors and air quality of open - type beef cattle fattening house were measured and analyzed. The results showed that there existed the problems which involved the lower air temperature, the higher relative humidity and the poor air quality in winter of Hei- longjiang province. It indicateds that the thermal insulation ability of the extemal building envelope should be enhanced, and the ventilation de- sign of the cattle fattening house should be improved, and the routine environmental management should be reinforced.
