甜菜是制糖的重要原料之一。发展甜菜生产,提高甜菜单位面积产糖量,对满足人民生活需要具有重要意义。目前,世界上许多先进国家(如日本、比利时、荷兰、瑞士等)甜菜平均亩产都在3吨以上,块根含糖率大于16％。而我国1971—1977年全国甜菜平均亩产不到1吨,单产不高,总产不稳,块根含糖率低。 Beet is one of the important raw materials of sugar. The development of sugar beet production, sugar beet per unit area to increase the amount of sugar, to meet the needs of people’s lives is of great significance. At present, many advanced countries in the world (such as Japan, Belgium, the Netherlands, Switzerland, etc.) have an average yield of more than 3 tons of sugar beet and a sugar content of more than 16% in the root tuber. The average beet production in China from 1971 to 1977 was less than 1 ton per mu, yield was not high, the total output instability, low sugar content in roots.
