黑龙江省不同类型肉牛舍冬季环境的研究

             

摘要

对2个规模化肉牛育肥基地具有代表性的4种育肥牛舍的温热环境及CO2浓度进行了测定。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。同时进一步分析表明,外围护结构保温隔热能力差、通风换气系统设计不完善、环境管理措施不力是造成这些问题的主要原因,而采用挤塑板为屋顶保温材料、冬季用塑料膜封闭敞开部分的高举架开放舍是一种较为适合黑龙江省气候特点的育肥牛舍;冬季把开放舍的敞开部分用双层充气塑料膜封闭,设置有保温层的排气管、并增加排气管的管径和高度将进一步改善育肥牛舍的环境。%The thermal environment and carbon dioxide concentration of four types beef house in two intensive beef farm were researched. The results showed that the problem which refers to the lower air temperature, the higher relative humidity and the foul air qulity were common in Heilongjiang beef house in winter. Through analysis we hold that the main reasons of causing these problems were the poor heat insulating ability of building envelope, the imperfect ventilation system design and the ineffective environmental management measures. The open house, which plastic extruded board was used for roof insulation materials, plastic film was used to seal the wall and the building eaveheight was higher, was suitable for Heilongjiang climate characteristics. The pipe diameter and height of the outlet should be increased and the insulator should be installed.
