内蒙古是我国甜菜糖生产基地之一,总产量居全国第二位。巴盟河套灌区甜菜种植面积和产量均占全区总面积和总产量的60%以上。因此,产量高低不仅直接影响到农民发展再生产的经济来源,而且对制糖工业及进一步改善城乡人民食品结构也产生一定影响。甜菜产量和含糖率的形成是一个复杂的过程,是多因子综合影响的必然结果,也是一个能量转化过程。能量过程,一般可用微分方程描述。为此,本文用灰色系统理论,以巴盟河

Inner Mongolia is one of the beet sugar production bases in China, with the total output ranking second in the country. The planting area and yield of beet in Hetao irrigation area of ​​Bainu both account for more than 60% of the total area and total output of the whole region. Therefore, the output level not only directly affects the economic source of farmers’ development and reproduction, but also affects the sugar industry and further improve the food structure of urban and rural people. The formation of sugar beet yield and sugar content is a complex process, which is the inevitable result of multifactorial comprehensive impact and also an energy conversion process. Energy process, the general differential equation can be described. To this end, this article uses the gray system theory to Bameng River
