九三垦区1974年开始种植甜菜,至1982年已有九年历史。在九年生产过程中,菜丝含糖波动幅度较大,高低差为3.452度:前六年平均力18.171％,后三年平均为17.122％,比较之下后三年降低了1.049度,可是九年中低于17％的只有两年(表1)。含糖升降是多方面因素构成的,据许多文献记载是和气象诸因子、品种、土壤、肥料、栽培措施等有密切关系。本文就九三地区甜菜菜丝含糖年度之间升降原因进行分析比较,并在品种、施肥、栽培措施方面与含糖升降关系提出一些看法。
Ninety-three reclamation area began planting sugar beet in 1974, to 1982, nine years of history. In the nine-year production process, the sweetener fluctuated greatly, with a height difference of 3.452 degrees: the average force of 18.171% in the first six years and the average of 17.122% in the latter three years, and a decrease of 1.049 degrees in comparison with the latter three years Only two years were below 17% in nine years (Table 1). Sugars rise and fall is composed of many factors, according to many documented and meteorological factors, varieties, soil, fertilizers, cultivation measures are closely related. In this paper, the causes of ascending and descending of sugar beet cabbage in ninety-three areas were analyzed and compared, and some opinions on the relationship between the sugar content and the variety, fertilization and cultivation measures were put forward.
