随着大田水稻生产上肥床旱育技术的推广和普及 ,杂交水稻制种采用的两段育秧技术已越来越不适应当前种子生产的发展需要。它不仅费工费时 ,浪费耕地 ,而且秧田用水矛盾突出。为此 ,我们通过几年的试验 ,掌握了父本肥床旱育技术 ,并在基地上全面推广了这一技术 ,取得了较为满意? With popularization and popularization of dryland cultivation techniques on paddy rice in field rice production, the two-stage seedling cultivation techniques adopted by hybrid rice seed production have become increasingly unsuited to the development needs of current seed production. It not only takes time and labor, wasted arable land, but also prominent contradiction of water for seedling. To this end, we passed several years of experiments, mastered the technology of dry fertilization of male parent bed, and comprehensively promoted this technology in the base, and achieved satisfactory?
