一九七八年冬内蒙古包头郊区沙尔心公社海岱大队的甜莱含糖率很低,只有1—3%为了弄清造成这种特殊低糖的原因,我们于第二年设专题进行了研究。主要是在出现特低糖的原地块重茬种植试验,目的是从生理、形态、营养、病虫害和环境等方面进行观察和分析,进而找出低糖成因。与此同时,我们还将该地块的土壤移到相隔300里远的太平庄甜菜
In the winter of 1978, the sugar content in the sweet potatoes of the Haidai Brigade in the Shar sub-commune in the suburbs of Baotou, Inner Mongolia was very low, only 1-3%. In order to find out the reasons for this particular low sugar, we set up a special project in the following year the study. The main reason is the trial of planting plots of low sugar in the original plots, the purpose is to observe and analyze from the aspects of physiology, morphology, nutrition, pests and environment and so on, and then to find out the cause of low sugar. In the meantime, we also moved the soil from the site to Taipingzhuang beet, which is 300 miles away
