摘要
对北方农牧交错带封闭式无供暖羊舍进行小气候观测研究结果表明 ,羊舍内地面温度日变化平稳 ,为-2 .5～ 0℃间 ,羊归牧卧盘时 2 0 :0 0至翌日 8:0 0地面温度比羊圈和野外均增加 11℃左右 ,使羊体与地面热交换大为减少。归牧后羊舍 0 .3m羊的生活高度处比羊圈温度高 10℃以上 ,舍内温度基本为 -2℃左右 ,相对湿度为58% ;1.5m高度处舍内温度维持在 0℃左右 ,相对湿度为 65% ,基本达到羊舍温度标准。一般羊圈基本无保温效果 ,但有一定防风效果 ,羊圈使 0 .3m高度处风速减少
The microclimate of the sheep-raising house in the no rt hern ecotone was observed in winter. The results show that the surface temperatu res in unheated houses are -2.5～0℃. It raises to 11℃ that is higher than that in the sheep pen and outside during 20.00 p.m ～8.00 a.m at the level of 0.3m. The air temperature in the house is -2℃ which is 10℃ higher than that in the sheep pen and outside and the relative humidity in it is 58%. The air temperatur e in the unheated sheep-raising house with an enlarged density can reach to 0℃ at the level of 1.5m and the relative humidity in it is 65%.
