| 摘 要： | 研究高肥量水平下不同玉米品种、种植密度与产量及其构成因素的关系。结果表明,不同品种对产量影响差异6.1%～46.6%,不同密度对产量影响差异1.98%～12.80%。郑单958种植密度9.0万株/hm2时产量最高,单产为13214kg/hm2。在此密度下主要通过群体来影响产量。

| Abstract: | Through the research on the relation between maize planting density and yield and yield constitutes factors,the result was that yield difference reached 6.1%-46.6% and 1.98%-12.80% as influenced by different maize varieties and different planting densities respectively.The optimum planting density for Zhengdan958 is 90 000 plants/ha.The highest Yield of 13 214 kg/ha was achieved under this density.Therefore the main influencing factors to the yield are different plant populations. |

| Keywords: | Maize Variety Density Super high-yield |
