本文根据红兴隆地区气象条件的特点，结合甜菜糖分积累期糖分增量的连续6年（1994～1999）测试结果，经统计分析后提出：1）甜菜糖分积累期的昼夜温差、日照时数不能满足糖分积累的适宜气象条件指标，成为影响本区甜菜含糖率进一步提高的障碍性气候因素；2）降雨量在甜菜生产中除其自身的效应外，还间接制约着有关气象因子，从而限制了甜菜糖分积累期含糖率的提高。
According to the characteristics of meteorological conditions in Hongxinglong area and the test results of 6 consecutive years (1994 ~ 1999) of increment of sugar content during sugar accumulation in sugar beet, the paper presents the following results: 1) The temperature difference between day and night during sugar accumulation in sugar beet, Which can meet the meteorological condition index of sugar accumulation and become the obstructive climatic factor that affects the further increase of sugar content in sugar beet in this area. 2) In addition to its own effect on rainfall, beet production indirectly restricts meteorological factors and thus restricts The beet sugar accumulation period increased sugar content.
