在作物育种工作中,国内外许多育种者利用气候差异北育南繁,或利用温室种植加代,大大缩短了育种进程,收到了良好的效果。但开展这项工作不仅要花费大量的人力、财力,且而在一些二年生作物上也不适用。为了探索甜菜加代繁育技术,我们在武威当地的自然气候条件下,经多年的试验、实践,总结出了一套秋播甜菜小母根培育技术。将甜菜采种株上采收的种子立即播种,在11月初严霜来临之前收获小母根。经窖内精
In the crop breeding work, many breeders at home and abroad make use of the differences in climate between north and south, or use greenhouse cultivation plus generation, which greatly shortened the breeding process and received good results. However, carrying out this work will not only cost a lot of manpower and financial resources, but also will not be applied to some biennial crops. In order to explore the technology of sugar beet plus generation breeding, we have concluded a set of small root cultivation techniques of autumn beet under the natural weather conditions in Wuwei County after years of experiments and practices. Seeds harvested on sugar beet seed plants are seeded immediately and young roots are harvested before the onset of severe frost in early November. After the cellar essence
