我县地处桂西北,是广西优良牛种——隆林黄牛的主要产区。冬季,在寒潮影响下,我县高寒山区(海拔1200米以上地区)容易出现凝冻(雨淞)、雪、霜冻等天气。如果耕牛防寒保暖工作做得不好,就会引起耕牛大批死亡。1966年冬至1967年春,由于耕牛过冬防寒工作疏忽,冷死耕牛6946头,占当时全县总牛数的12.2％。自1966是冬至1980是春,全县共冷死耕牛17092头,损失巨大。本文试从我县逐年冷死耕牛的数字对比气象资料,找出影响耕牛过冬的气象因子,分析耕牛过冬的气候条件,为保护耕牛过冬提供气候依据。
My county is located in northwest Guangxi, Guangxi is a good breed - Longlin cattle main producing areas. In winter, under the influence of the cold wave, the frozen alpine (rain song), snow, frost and other weather are prone to appear in the alpine mountainous area (above 1200 meters above sea level) in our county. If the cold warm cattle work done well, it will cause a large number of cattle deaths. From 1966 to the spring of 1967, 6946 cold-headed cattle died, accounting for 12.2% of the total number of cattle in the county at that time due to the negligence of winter cattle in winter. Since 1966 is the winter solstice 1980 spring, the county cold-headed cattle were 1,792, a huge loss. This paper tries to compare the meteorological data of cold cattle in our county from year to year to find out the meteorological factors that affect the survival of cattle in winter and analyze the climatic conditions of cattle in winter so as to provide climate basis for the protection of cattle in winter.
