摘　　要：选用先玉335、郑单958和512-4不同株型的夏玉米品种,设置60 000株/hm2和75 000株/hm2两个种植密度和50、60、70、80 cm等行距以及80+40 cm宽窄行5个行距处理,研究不同种植模式对夏玉米的生理生态效应和产量影响。结果表明,60 cm等行距处理下,群体光辐射分布较为合理,田间小气候的控制较为安全,有利于提高抗逆性,能够在不同的品种和密度条件下获得较高产量,是目前黄淮海区夏玉米机械化生产较为适宜的播种行距。Three different summer maize cuhivars with different morphological types（Xianyu335, Zhengdan958 and 512-4）, two plant population densities（60 000 plants/ha and 75 000 plants/ha） and five row spacing treatments （50, 60, 70, 80 cm and 80＋40 cm） were used to research the effect of maize planting patterns on the physiological and ecological effects and yield. The results showed that, the row spacing of 60 cm not only had suitable canopy light radi- ation, but also presented safety field microclimate more safety, the quality of resistance could be enhanced. In the five row spacing treatments,the yield of 60 cm row spacing was highest at different varieties and densities.Therefore, 60 cm is the suitable row spacing for mechanized seeding of summer maize in Huanghuaihai region.
