以株两优120为供试水稻品种,在湘南丘陵地区进行早稻“3415”施肥试验,以各处理水稻农艺性状和产量的数据为基础进行灰色关联度分析,研究该地区早稻主要农艺性状与产量的关联度。结果表明:水稻主要农艺性状对湘南丘陵早稻产量的关联度大小依次为:株高>有效穗>总粒数>穗长>千粒重>实粒数。
In this study, the early rice “3415” fertilization experiment was conducted in the hilly area of southern Hunan with Zhu Liang 209 as the tested rice variety. Based on the data of agronomic traits and yield of each treatment, the gray correlation analysis was conducted to study the main agronomic traits of early rice in this area. Relevance to production. The results showed that the main agronomic traits of rice related to the yield of early rice in southern Hunan were as follows: plant height> effective spike> total grain number> ear length> 1000-grain weight> grain number.
