| 摘 要： | 试验通过玉米种植密度对产量及其结构的差异研究,基本明确了种植密度与产量构成要素的变化关系,以及随种植密度增加,产量构成要素对玉米产量的贡献变化。结果表明,在一定密度条件下,穗数是构成产量的主要因素,对产量贡献最大。在适宜种植密度范围内,穗粒数和百粒重是构成产量的主要因素,对产量贡献最大。

| Abstract: | In this paper, the change relationship between planting density and yield component factors was defined basically by researching the differences of the yield structure of the different corn planting density, and with the increase of planting density, the variation of yield component factors contributed to the maize yield was also cleared. The results show that panicle number is the main factor which affecting the yield and has the maximum contribution to the yield under the certain density. The grain number and 100 grains weight are the main factors which affecting the yield and have the maximum contribution to the yield within the suitable planting density. |
