杂交晚稻的大面积推广,出现了历史上前所未有的晚稻单产超早稻。但1984年各地反映种子发芽率普遍降低,全县造成经济损失达十二万九千多元(调入种子一项)。又因杂交稻种子发芽率的高低,关系到能否种足种好杂交稻的一个重要因素。为了吸取这个教训,切实采取有效的贮藏保管措施,以提高种子发芽率,育好矮壮带蘖秧苗,确保杂交晚稻丰产丰收。 Large-scale hybrid rice promotion, there has been an unprecedented history of late rice yield super rice. However, in 1984, the germination rate of the seeds was generally reduced in all parts of the country, causing an economic loss of over 129,000 yuan (transferred to seeds). Because of the hybrid rice seed germination rate, is related to the ability to plant enough to grow an important factor in hybrid rice. In order to learn from this lesson, effective measures to take effective storage and storage to improve seed germination rate, breeding short stout with tillering seedlings to ensure high yield late hybrid rice harvest.
