北方农牧交错区奶牛场舍内外有害气体的季节性变化

本试验旨在探究北方农牧交错区牛舍内外有害气体的变化规律,为有效控制奶牛舍有害气体提供理论依据。试验选择内蒙古西部农牧交错区某奶牛场作为研究对象,在一年中四个季节测定牛舍内外的有害气体含量,每季节连续测定三天。结果表明,舍内外有害气体有一定的季节性变化规律;舍内有害气体含量明显高于舍外,但均未超标。

Seasonal Change of Noxious Gas inside and outside the Dairy House in Farming-pastoral Transition Area of Northern China

The present experiment was conducted to study the seasonal change of noxious gas inside and outside the dairy house in farming-pastoral transition area of northern china and in order to provide scientific basis for controlling noxious gas in dairy house.In the experiment,a dairy farm was selected in the farming-pastoral transition area of western Inner Mongolia,and the contents of noxious gases inside and outside the dairy house were detected during spring,summer,autumn,and winter respectively,and continuous three days for each season.The results showed that there was a seasonal change of noxious gas inside and outside the dairy house,and the contents of noxious gas inside were higher than those outside,but all those were below the critical value.
