糖用甜菜属于藜科甜菜属二年生作物(江、浙地区属一年生作物)。从1896年在黑龙江省阿城市试种起,到今天已经有近百年的历史。多年来,在科技人员的努力下,甜菜种子的研制、繁育发生了巨大的变化。甜菜种子由二倍体变为三倍体,由复果多粒种变为单果单粒种,由机制单芽种变为遗传单芽种,由裸种变为包衣种,种子繁育经销由个体、小面积、手工操作向大公司、大面积、机械化生产加工方向发展。目前我国生产上大多使用三倍体多粒型甜菜种,在纸筒育苗上使用三倍体机切单粒种,或引进使用
Sugar beet belong to Chenopodiaceae Beet is a biennial crop (Jiang, Zhejiang area is an annual crop). From 1896 in Heilongjiang Province, try planting in A city, to today has nearly a hundred years of history. Over the years, in the efforts of scientific and technological personnel, beet seed research and breeding has undergone tremendous changes. Beet seeds from diploid to triploid, from the complex fruit variety into single fruit single species, the mechanism of a single bud into a single genetic seed, from the naked species into a coated species, seed breeding distribution from Individuals, small area, manual operation to large companies, large area, mechanized production and processing direction. At present, most of the production in our country use triploid multi-grain sugar beet species, triploid paper machine seedlings on the use of single species, or the introduction of the use
