不同品种青贮玉米形态特征及生育进程的变化

对6个不同青贮玉米品种形态特征指标和生育进程进行了系统观测,结果表明,供试的六个青贮玉米品种,在株高、穗位高、总叶数、穗位叶叶序以及乳熟期绿叶面积的品种间差异达到显著或极显著水平。科试1号、东陵白和金坤9号总叶片数最多,均显著高于其他品种。乳熟期绿叶面积以科试1号最高,达2.3m2/株,显著高于其它供试品种。多分蘖品种科试1号与植株高大品种在所有供试品种中,植株综合性状表现较好,这是其形成较高生物产量的形态学基础。科试1号和东陵白适宜在呼和浩特地区大面积推广种植。

Changes of Morphological Characters and Growth Process of Different Silage Maize

Morphological characters and growth process of different silage maize were studied in this trial, and the results showed that plant height, spike distance from surface, total leaves, spike leaf order and leaf areas in milk stage in different silage maize had significant difference. No.1 Keshi, Donglingbai and No.9 Jinkun had larger total leaves, and significantly higher than other cultivars. Green leaf areas in milk stage of No.1 Keshi was 2.3 m2 per plant, significantly higher than other cultivars, and its integrated characters was also better than other cultivars. In general, No.1 Keshi and Donglingbai were adapted in Huhhot district.
