我县杂交稻繁殖制种已达10余年,前几年因对种子质量管理重视不够,在杂交稻推广中曾出现隔年稻种常催芽烂种,种子纯度下降等质量问题。对此,我们认真总结经验教训,主要作法是:一、大力加强种子基础设施建设1.首先改善仓贮条件。我县原有仓库是70年代初建的简易仓,不利于杂交稻种的安全贮藏。从1989年起连续抓仓库建设,已建标准库房1200平方米,其中建越夏仓库300平方米,安装空调和除湿机20台。 Hybrid rice breeding in our county has reached more than 10 years, a few years ago because of inadequate attention to the quality of the seeds in the promotion of hybrid rice appeared in the following year often germinated seeds, seed purity decreased quality problems. In this regard, we conscientiously sum up experiences and lessons, the main practices are: First, to vigorously strengthen the seed infrastructure 1. First of all, improve storage conditions. The original warehouse in our county was a simple warehouse built in the early 1970s, which is not conducive to the safe storage of hybrid rice varieties. From 1989 onwards continuous warehouse construction, has built a standard warehouse of 1,200 square meters, of which build more summer warehouse 300 square meters, the installation of air-conditioning and dehumidifier 20.
