果树一般都喜热、喜湿,要求光照充足。右玉县地处高寒山区,最高点海拔1,975米,最低点海拔1,230米,年平均气温3.6℃,最低气温-40.4℃,最大冻土深度169厘米,累年平均降水442.8毫米,年均日照2916.6小时,稳定通过10℃的平均积温为2,257.9℃,在这样寒冷、干旱地区发展果树曾经是人们不可思义的。但是,目前右玉全县实有果树面积4,869亩,果品年产量13万余斤,其中苹果3万余斤,果实着色好含糖量较高。从而充分说明,只要合理利用气候资源,调节小气候条件,高寒山区是可以发展果树的。一、利用小气候区发展小果园。右玉县
Fruit trees generally like hot, hi wet, requiring adequate light. Youyu County is located in the alpine mountainous area, the highest point 1,975 meters above sea level, the lowest point at 1,230 meters above sea level, the annual average temperature of 3.6 ℃, the lowest temperature of -40.4 ℃, the maximum permafrost depth of 169 cm, the average annual rainfall of 442.8 mm, average annual sunshine 2916.6 In the past, the average accumulated temperature at 10 ° C was 2,257.9 ° C steadily. The development of fruit trees in such cold and arid areas once was unimaginable. However, at present, there are 4,869 mu fruit trees in Youyu County, with an annual output of more than 130,000 jin of fruit, including more than 30,000 jin of apple fruit. This fully shows that as long as the rational use of climate resources, regulation of microclimate conditions, alpine mountains is the development of fruit trees. First, the use of microclimate zone development of small orchards. Youyu County
