十多年来,我们坚持搞品种提纯复壮,对防止良种混杂退化,发展棉花生产起了促进作用。但是,要高速度地发展棉花生产,光守摊摊不行,还得勇闯新路。近几年, 我们改革了原种繁育技术,提高了棉花繁种效果。 For more than a decade, we have persisted in purifying and rejuvenating breeds and played a promoting role in preventing hybrid degeneration and developing cotton production. However, if we want to develop cotton production at a high speed and we can not share it with our own, we have to break new ground. In recent years, we have reformed the original breeding technology and improved the cotton breeding effect.
