摘　　要：为了探究羊舍环境参数变化规律以及光控措施对羊舍环境的影响,优化环境控制所需的布点数目和位置,本试验结合陕北地区空废化窑洞再利用问题,运用畜禽用多功能气体分析仪(CN201410008619.7)对有害气体(二氧化碳、氨气、甲烷)浓度、光照、风速、温湿度等环境参数指标进行为期一个月的全天候环境数据检测,选取羊只全部在舍内期间的试验数据进行气体差异显著性分析、舍内各类气体拟合度比较、有害气体浓度数据变化回归方程的构建。结果显示,窑洞舍内空间三点的甲烷和二氧化碳气体浓度存在显著差异(P<0.05)。光控对窑洞羊舍有害气体浓度的变化有影响,有害气体浓度变化曲线趋势对比变化较大,氨气浓度低于非光控窑洞羊舍,二氧化碳和甲烷浓度高于非光控窑洞羊舍,但浓度变化趋势一致。试验全程两舍羊只均处于环境舒适区,无明显应激反应,因此空废化窑洞畜牧化利用养羊可行。This experiment aimed to investigate the variation of environmental parameters in sheep caves and the impact of light control measures on the sheep cave environment,and to optimize the number and placement of points for environmental control.The experiment utilized a multi-functional gas analyzer for livestock and poultry(CN201410008619.7)to monitor harmful gas concentrations,light intensity,wind speed,temperature,and humidity continuously in the context of reusing abandoned cave dwellings in the northern Shaanxi region.The experimental data collected while the sheep were inside the cave were used for analysis of gas concentration differences,comparison of gas fitting degrees inside the cave,and construction of regression equations for harmful gas concentration variations.Results showed there were significant differences(P<0.05)in methane and carbon dioxide gas concentrations at three points within the cave.Light control had an impact on the variation of harmful gas concentrations in the caves.The trend of changes in harmful gas concentrations varied considerably,with ammonia concentrations lower than those in non-light-controlled caves,and carbon dioxide and methane concentrations higher than those in non-light-controlled cave,but with consistent concentration change trends.Throughout the experiment,the sheep in both caves remained in a comfortable environment without obvious stress reactions,indicating the feasibility of utilizing abandoned cave dwellings for sheep husbandry.
