内蒙古巴盟是国家甜菜生产主要基地之一。目前甜菜种植面积已发展到三十余万亩,一九八五年按收购量平均亩产已达2578.0公斤。但含糖率有缓慢下降趋势,这是甜菜制糖工业发展面临的一个突出问题,针对这个问题我们于1980年通过不同颜色塑料小拱棚,试图从改变光质和加大昼夜温差两个方面对糖分影响进行探讨,并获得可喜的结果。1986年又选择对糖分影响极显著和中间状态的颜色进行重复试验并增加一些测试内容,现将结果综合报告如下。
Inner Mongolia Bam is the national sugar beet production base. At present, the area of beet cultivation has grown to more than 300,000 mu. In 1985, the average mu yield per acquisition reached 2,578.0 kg. However, there is a slow downward trend in the sugar content. This is a prominent issue facing the sugar industry in sugar beet industry. In response to this problem, we tried to change the light quality and increase the temperature difference between day and night Discuss the impact of sugar, and get gratifying results. In 1986, they also chose to repeat the test on colors with extremely significant influence on the sugar content and in the middle state and add some test contents. The results are reported as follows.
