摘要
为筛选适宜山区小型机械化种植的玉米新品种,采用裂区设计,开展了玉米新品种筛选试验。结果表明,通过对播种效果分析可知,参试玉米品种播种均匀性相差不大,粒距合格指数较好的品种有3个,重播率较小的品种有3个,漏播率较小的品种有4个;通过群体整齐度分析可知,株高整齐度较好的品种有3个,穗位高整齐度较好的品种有3个;通过对苞叶特性分析可知,苞叶特性较好的品种有5个。综合考虑,有3个玉米新品种适宜山区小型机械化种植,即中单901、宝玉007、京农科728。
In order to select new maize varieties suitable for small-scale mechanized planting in mountainous area,a maize variety selection test was conducted by split plot design.The sowing effect analysis showed that the difference of sowing uniformity of testing maize varieties was little.There were 3 varieties with good grain distance qualified index,3 varieties with low reseeding rate and 4 varieties with low missing seeding rate.The population uniformity analysis showed that there were 3 varieties with good uniformity of plant height and 3 varieties with good uniformity of spike height.The bract character analysis showed that there were 5 varieties with good uniformity of bract leaf.Comprehensive considered,there are 3 new maize varieties suitable for small-scale mechanized planting in mountainous areas,which are Zhongdan 901,Baoyu 007,Jingnongke 728.
