种性纯、品质优、产量高是制种甜菜的生产目标。我场1983年试搞甜菜采种,1990年面积达4380亩,单产由109.6kg提高到245.4kg(年递增17.4％),到1988～1989年一级种子基本上达到100％。实践表明,采种甜菜产质量与栽培技术措施及收获阶段的管理关系密切。栽培技术是提高采种甜菜产质量基础适期早播 适期早播能充分利用冬前温、光资源,且在越冬前培育成壮秧,形成一 Pure species, excellent quality, high yield is the production of sugar beet production goals. In 1983, I started beet harvesting. In 1990, the area was 4,380 mu. The yield was increased from 109.6kg to 245.4kg (an annual increase of 17.4%). From 1988 to 1989, the first grade seeds basically reached 100%. Practice shows that the quality of sugar beet growing and cultivation techniques and harvesting stage management is closely related. Cultivation technology is to improve the quality of the base of sugar beet seed production suitable early sowing early sowing can make full use of early winter temperature and light resources, and in the winter before breeding into strong seedlings to form a
