【摘要】 为了解黑龙江省冬季育肥牛舍的环境状况,对两个规模化肉牛育肥基地具有代表性的4栋育肥牛舍的温热环境及CO2浓度进行了全面的测定,目的是为今后肉牛舍的设计及饲养管理方式的改进提供理论依据。测定结果表明,黑龙江省冬季的肉牛舍普遍存在着气温低、湿度高、空气质量差等问题。测定的结果发现,挤塑板是一种合适的畜舍保温材料;增加牛舍的举架高度,有利于牛舍的保温和防潮;如果能将高举架舍和低举架舍的塑料膜换成保温性能强的材料,牛舍内的环境将得到进一步的改善。更多还原

【Abstract】 The thermal environment and carbon dioxide concentration of four types beef house in two intensive beef farm were researched in order to know the winter envoronment condition in Heilongjian province and to provide the theoretical basis with beef house design and environmental management.The results indicated that problems which refers to the lower air temperature,the higher relative humidity and the foul air qulity in beef house of Heilongjiang in winter were widespread.We hold that extruded sheet is a kind of suitable thermal insulation material for animal house.Higher marginal height is favourable for beef houses‘ heat preservation and moistureproof.If the plastic film is replaced by heat insulator,the environment of beef house would be better.更多还原
