河套灌区是内蒙古自治区的重要甜菜基地之一。早在1936年曾推广栽培甜菜,后因抗战而中断。建国后,甜菜种植面积随着我国制糖工业的发展,城乡人民生活的需要,作为农村主要经济来源而得到迅速发展。1979年以来甜菜生产连续五年获得丰收。1983年全灌区种植甜菜30万亩,总产15亿斤,平均单产5000多斤,创历史最高水平。但是,由于各年气候条件的不同,甜菜含糖率的年际波动较大,高糖年含糖在19％以上,低糖年含糖则低于16％。为此,本文采用积分回归、事件相关、数值相关和偏相关及回归分析等统计学方法,对河套灌区甜菜含糖率与相应的气侯因子进行统计分析。试图定量地探讨甜菜含糖率与光、热、水等农业气候条件之间的关系及其变化规律;寻求含糖率上升和下降的原因及关键时段、影响程度等。为趋利避害,提高甜菜含糖率采取有效的农业技术措施提供科学依据。 Hetao Irrigation District is one of the important sugar beet bases in Inner Mongolia Autonomous Region. As early as 1936, it promoted the cultivation of sugar beets and was interrupted by the war. After the founding of the People’s Republic of China, the area of ​​beet cultivation has rapidly developed as the main source of income for rural areas as the development of China’s sugar industry and the needs of urban and rural people’s livelihood. Beet production has enjoyed a bumper harvest for five years in a row since 1979. In 1983, 300,000 mu of beets were planted in the whole irrigation area with a total output of 1.5 billion kilograms, with an average yield of 5,000 kilos, the highest record in history. However, due to the different climatic conditions in different years, the annual sugar content of sugar beet fluctuates widely, with the sugar content in high sugar sugar being above 19% and the sugar content in low sugar sugar being less than 16%. Therefore, in this paper, the statistical analysis of sugar content of beet and corresponding climate factors in Hetao Irrigation District was made by using the methods of integral regression, event correlation, numerical correlation and partial correlation and regression analysis. This paper attempts to quantitatively explore the relationship between the sugar content of sugar beet and the agro-climatic conditions such as light, heat and water, and the changing rules of the sugar beet content. The reasons for the rising and falling of the sugar content, the key period and the degree of impact are also discussed. In order to provide the scientific basis for taking advantage of agricultural techniques and measures to reduce losses and increase the sugar content of sugar beet,
