摘要 试验采用单因素随机区组设计,选择了当地有一定种植面积的7个中晚熟玉米杂交种,通过对不同品种生育时期、生长性状和理论产量与实际产量等方面进行比较,分析不同品种在盂县的产量表现,为适宜该生态区种植的玉米杂交种提供推广依据。结果表明,沃玉963号生长发育较快,后期脱水快,产量高,具体表现为:可见叶、展开叶发生速度较快,植株较高,后期成熟时植株青枝绿叶,延长了群体叶片功能期,增加了籽粒质量,产量表现较好。沃玉963号玉米杂交种是适宜太行山中晚熟生态区推广的优良品种。 In this experiment, with the single factor random block design, selected seven middle-late mature maize hybrid varieties which were planted, the paper compared growth stage, growth traits, theoretical yield and actual output of different varieties, analyzed the yield performance of different varieties in Yuxian. The experiment provided the promotion basis about what variety is more appropriate in this ecological region. The result indicated that Woyu 963 had faster growth, faster late dehydration and high productivity. The detailed advantages included the faster growth of visible and expanding leaves, high plant height, matured plants with green leaves at late stage,the extended duration of leaf function, increased the quality of the grain and good productivity. So Woyu 963 maize hybrid is a good variety that is proper to be planted in middle-late mature ecological region in Taihan mountains.
