摘  要:
根据区域自然降雨条件,选择适宜的密植型品种是保证玉米稳产高产乃至粮食安全生产的重要途径。在晋中盆地雨养条件下,选用生产上推广的密植型代表品种,通过分析穗期不同玉米品种间形态指标与产量的相关性,结果表明,穗期地上部干、鲜物质积累以及穗期株高增长量、抽雄期株高可作为鉴定玉米产量的形态指标,且品种以大丰30的产量最高。这不仅为该区域选择适宜的品种提供了理论基础,同时对提升山西省玉米总体种植水平也具有重要意义。

摘  要:
At the different nature rainfall zones, choosing proper high-populations maize variety was the important way to ensure maize high and stable yield and food security. The experiment under nature rainfall conditions in Jinzhong basin, selected the representative high-populations maize varieties in agriculture production, analyzed the relativity between yield and morphological indexes of different maize varieties at heading-stage, and selected the indexes of underground dry and fresh bio-accumulations, and height growth of heading-stage and height of tassel phase of maize, and these indexes could be the important morphological indexes to evaluation maize yields, Dafeng 30 was the highest yield. It not only provided foundations of the theoretical research for choosing proper maize varieties,but also had great significant to improve maize total productions in Shanxi province.
