针对杂交水稻种子带病较多,颖壳闭合不完全,活力低于常规稻,对贮藏、浸种、催芽、育秧等过程中的不良环境条件反应特别敏感的特点和为了提高杂交水稻种子的发芽势、发芽率、种芽素质、成秧率及壮秧率,我们进行了几种浸种催芽方法的试验。 1987~1991年连续5年以当年收获籼型杂交晚稻组合“V优64”的种子为材料进行如下进程的处理:第一天按5 kg水和3.5 kg种子的比例,将已准备好的种子袋浸入盛水的小木桶里,翻动、拌和后放在避风向阳处浸种
In order to improve the germination potential of hybrid rice seeds, the characteristics of the hybrid rice seeds are more diseased, incomplete closure of glume shells and lower vigor than conventional rice, especially sensitive to adverse environmental conditions during storage, soaking, germination and seedling raising. , Germination rate, seed germination quality, seedling emergence rate and strong seedling rate, we conducted several kinds of soaking seed germination test. For the fifth consecutive year from 1987 to 1991, the seeds of indica hybrid late rice combination “V You 64” were harvested for the following five days: The first day, 5 kg of water and 3.5 kg of seeds were used to seed the prepared seeds Immersed in a small bucket of water, flip, mix and shelter in the sun at the shelter
