| 摘 要： | 采用裂区设计研究了种植方式、种植密度及施肥量对玉米产量的影响。结果表明：等行距种植的玉米产量均高于宽窄行种植；种植密度60 000株/hm2的产量高于45 000株/hm2；施肥增产作用明显，但施肥处理间产量差异不显著。种植方式和密度影响肥料效益和利用率。

| Abstract: | This experiment was conducted in a split-plot treatment arrangement to explore the influence of plant arrangement, density and fertilization on a maize hybrid. The results showed that grain yield of equidistant arrangement were higher than that of wide-narrow arrangement. The density at 60 000 plants/ha hectare helped produce higher yield than that at 45 000 plants/ha hectare. Fertilization played a significant role in yield increase, but there was not significant between two rates of fertilizer applied. The results also showed that plant arrangement and density had an influence on fertilizer effect and fertilizer use efficiency. |
