摘　　要：目的:研究冬季不同月份可繁母牛敞棚栏内是否设置挡风墙,对风速、二氧化碳、氨气、硫化氢浓度的影响,试验方法:试验分为三组分别是挡风栏,敞棚栏和牛舍外,每组测定5个点,连续测定三天。试验结果显示寒冷季节设置挡风墙对肉牛舍内风速方面在十一月、三月、五月有显著差异(P 【0.05),二氧化碳方面在十一月、三月、四月有极显著差异(P 【0.01),由于空气中不含氨气和硫化氢,所以无测量结果。结论:设置挡风栏可繁母牛舍风速得到很好控制,但是却显著增加了二氧化碳含量。The effects of wind-break walls on wind speed, carbon dioxide, ammonia and hydrogen sulfide concentration were studied in different months of winter. The test is divided into three groups: the windshield, the shed and the cowshed. Five points were measured in each group and continuously measured for three days. The test results show that there is a significant difference in the wind speed in the beef barn in November, March and May in the cold season (P
