| 摘 要： | 为了探索夏玉米在德州地区的最优栽培模式，采用裂区设计，对不同施肥量与种植密度时夏玉米的产量及效益的影响进行了试验研究。结果表明，施肥量及密度对夏玉米产量的影响均达到显著水平，且肥料和密度的互作效应显著。产量达629．58kg／667m2且效益最大的栽培措施是：追施氮肥30．4kg／667m2，种植密度4000株／667m2。

| Abstract: | The present study was carried out to characterize the best plant pattern of summer maize, in Dezhou region. The effects of fertilization and density on yield and benefits of summer maize were investigated by split-plot design. The results showed that the yield was significant correlated with fertilization and density. The interaction effects of fertilization and density was obvious. The plant means of the best benefits and yield with 629.58 kg/667m2 were 30.4 kg/667m2 as topdressing nitrogen and 4 000 plant/667m2 as plant density. |
