选用不同类型的夏玉米品种进行了种植比较,研究其在当地(阿拉尔)特定气候条件下的主要生长性状与产量性状之间关系,进而筛选出适合南疆夏种的玉米品种。结果表明:夏玉米产量与生育期长短显著相关,并且与穗部呈正相关的性状大小排列为单穗重>穗粒数>穗长>百粒重>双穗率,与生长形态呈正相关的性状大小排列为穗位高度>空秆率>株高。因此,在选择夏玉米品种时首先要考虑生育期,以保证能正常成熟为准,并应注意对穗重较高、穗粒数较多、穗长较长、穗位较低等性状的考察。早熟品种新玉29和新玉13号产量表现较好,可为南疆复播玉米品种,但应注意防止新玉29号的后期倒伏。
The different types of summer maize varieties were compared for planting, and the relationship between the main growth traits and the yield traits under the local (Alar) specific climatic conditions was studied, and the maize varieties suitable for the summer races of southern Xinjiang were screened out. The results showed that there was a significant correlation between summer maize yield and the length of growing stage and the positive correlation with the ear was the order of single panicle weight> spike grain number> ear length> 100-grain weight> double-spike rate, which was positively correlated with the growth pattern The size of the arrangement for the ear height> empty stalks> plant height. Therefore, the choice of summer maize varieties should first consider the growth period, in order to ensure the normal maturity prevail, and should pay attention to high spike weight, spikelets more, longer spike length, lower ear position inspection . The yield of early maturing cultivars Xinyu 29 and Xinyu 13 were better, which could be the varieties of maize sowing in southern Xinjiang, but should be taken to prevent the late lodging of Xinyu 29.
