| 摘 要： | 为了探明玉米种植的最优方式，试验采用裂区设计，研究不同耕作方式、种植密度及施N肥量对玉米的产量和农艺性状的影响。结果表明：不同的耕作方式和不同施N肥量玉米的产量差异均达显著水平，不同种植密度的玉米产量差异不显著。在各组合中，以平作耕作方式、密度67500株/hm2、施N量为112.5 kg/hm2，玉米产量最高；耕作方式对玉米棒三叶叶面积和株高影响差异达显著水平，对最大叶面积指数和茎粗影响差异不显著；密度对玉米最大叶面积指数、棒三叶叶面积和茎粗影响差异显著，对株高影响差异不显著；施氮与不施氮之间最大叶面积指数、棒三叶叶面积、茎粗和株高差异显著。 |

| Abstract: | To investigate the optimal way of corn planting,a split-plot design was adopted in this study.The effects of plant arrangement,plant density and N fertilizer levels on the yield of maize and agronomic traits were studied.The results showed that： among three factors,the plant arrangement and the N fertilizer was significantly impact on the yield.But there was no significant difference for yield in three kinds of densities.The most optimum treatment was flat planting,67500 plants per hm2,112.5 kg/hm2 N fertilizer.The plant arrangement reached significant level to leaf area of three ear-leaves and the plant height,and not reached significant level to the largest of leaf area index and stem diameter.The plant density was reached significant level to the largest of leaf area index,leaf area of three ear-leaves and stem diameter,and not reached significant level to the plant height.With and without application of N fertilizer,the largest of leaf area index,three ear-leaves,stem diameter and the plant height was reached significant level. |
| Keywords: | maize plant arrangement N fertilizer plant density yield agronomic traits |
