| 摘 要： | 本文对当前北京地区奶牛场防暑降温问题进行了初步的较系统的探讨。文中在评价了奶牛场不同环境的暑热程度基础上,通过三种降温措施的比较,提出了以蒸发降温为主的夏季环境管理方法。并从气象资料的统计分析、通风量的模拟计算、蒸发降温装置的试验设计等方面对该管理方法的实现进行了论证.

| Abstract: | In this research, systematic experiments have been made on the problems of cooling for dairy cows under present conditions of the farms in Beijing region. Based on the environmental evaluation of the dairy cows in summer seasons with the Improved Temperature Humidity Index, a management procedure for hot environment of dairy farms has been advanced through the comparison of three cooling methods which had been tested in the research. Before the conclusions were got, discussions and demonstrations had been made from three aspects, they are statistics and analysis of weather data, simulating calculation of ventilation rate and test for design of a evaporative cooler. As the results, data and other informations which can be used as references in dairy production and further studies are provided. |
