宁夏回族自治区地处中温带,属典型大陆性气候。干旱少雨、气候温凉、日照充足、昼夜温差大月有黄河自流灌溉之利。因此这里种植甜菜发展制糖工业很有前途。据有关资料统计1970—1975年全区甜菜菜丝平均含糖18.4度,也就是说银川糖厂自1970年投产以来菜丝含糖一直保持18度以上水平(除1971年略低外)。但是此后几年甜菜食糖出现了波动下降的趋势,以1978年下降最为严重,仅15.9度。近几年又有些回升(见表)。 Ningxia Hui Autonomous Region is located in the temperate zone, is a typical continental climate. Drought and dry weather, cool climate, adequate sunshine, large temperature difference between day and night, the Yellow River gravity irrigation. So sugar beet cultivation here is very promising. According to relevant statistics, the average sugar content of beet cabbage in the region during 1970-1975 was 18.4 degrees, that is to say, the sugar content of the cauliflower in Yinchuan sugar mill remained above 18 degrees (except slightly lower in 1971) since it was put into production in 1970. However, beet sugar has shown a tendency of fluctuating declines in the following years, dropping most seriously in 1978 at only 15.9 degrees. Some rebound in recent years (see table).
