| 摘 要： | 为充分挖掘旱地玉米生产潜力，找出适宜本地区的高产关键栽培技术措施，采用裂区设计研究不同类型品种和密度对旱地玉米生长发育及产量的影响。结果表明，紧凑耐密型品种‘郑单958’经济产量、生物产量、收获指数显著大于稀植大穗型品种‘咏丰1号’，分别较‘咏丰１号’增加15.1%、7.8%、6.8%。经济产量和生物产量随着密度的加大明显增加，但‘郑单958’在密度为7.2万株/hm2、‘咏丰１号’在密度为4.8万株/hm2时，都有较低的生物产量和较高的经济产量，源库关系更加协调。

| Abstract: | To make full use of dryland maize potential productivity and find suitable key cultivated measures of maize high yield in this area, a field trial with two varieties （ZhengDan 958 and Yongfeng No.1） was conducted in 2009 in Yangqu, Shanxi, China in a split-plot treatment arrangement to explore the influence of different varieties and densities on growth and yield of maize in dryland. The economic yield, biomass yield and harvest index of compact-planting and close density tolerant maize ‘ Zhengdan958 ’ was 15.1%, 7.8% and 6.8% higher than those of rare-planting and large-size spike maize ‘ Yongfeng1 ’ , respectively. The economic yield and the biomass yield increased with increasing planting density. When the density of ‘ Zhengdan958 ’ was 72000 plants per hm 2 and the density of ‘ Yongfeng1 ’ was 48000 plants per hm 2 , they could keep lower biomass yield and higher economic yield, and could achieve harmonious relationship between leaf source and kernel sink. |
