六师垦区位于欧亚大陆腹地,地处天山北麓准格尔盆地东南缘,属于中温带大陆性气候。气温年较差大,热量条件较好。棉花这种喜温作物为六师的重要经济作物,而六师苗期和成熟期棉花常遇霜冻,所以,霜冻的研究也就显得尤为重要。本文以六师新湖农场气象站1981-2012年气象资料为代表,计算、分析初霜期、终霜期及无霜期的变化趋势、分布频率及周期,从而分析其气候特点及内在联系。
Sixth Reclamation Area is located in the hinterland of Eurasia, is located in the northern foot of Tianshan Junggar Basin, southeastern margin, belongs to the temperate continental climate. Bad temperature year, good heat conditions. The thermophilic crop of cotton is an important economic crop of the 6th Division, while the 6th seedling and mature cotton often frost, so the study of frost is particularly important. Based on the meteorological data from 1981 to 2012 of Xinhu Farm Weather Station of Liuzhou Normal University, this paper calculated and analyzed the change trend, distribution frequency and period of the initial frost period, the final frost period and the frost-free period, and analyzed the climatic characteristics and internal relations.
