| 种植方式是影响玉米产量的重要因素，在玉米高产创建中常采用的种植方式有单穴单株、一穴双株和“121”（单双株交替）等方式。为了研究玉米产量性状对不同种植方式的响应，选用当地推广面积较大的6个品种，于2015-2016年在山西省襄汾县永固乡开展田间试验。玉米收获前田间取样，调查果穗穗部性状，分析不同种植方式间的穗粒数、百粒重和产量差异。结果表明：不同种植方式对玉米穗粒数和百粒重的影响不显著，但对产量的影响显著；单穴单株种植在一定程度上能够提高玉米的穗粒数、百粒重，显著提高产量。在玉米生产中，推荐采用单穴单株种植方式。 |

| Planting pattern is an important factor affecting maize yield. For the high yield in maize，the planting patterns often include single hole for single plant, one hole for double plant and "121" mode (alternating single and double plants). In order to study the response of maize yield traits to different planting patterns, six varieties which were extended by larege area were selected to carry out field experiments in Yonggu Township of Xiangfen County in Shanxi Province from 2015 to 2016. Field samples were taken before maize harvest to investigate the ear characters and to analyze the effects of different planting patterns on the grains per ear, hundred-grain weight and yield characters. The results showed that different planting patterns had no significant effect on the grains per ear and hundred-grain weight, but had a significant effect on the yield; Single grain planting coud improve the grains per ear and hundred-grain weight of maize to a certain extent, and significantly improve the yield. In maize production, single hole for single plant planting is recommended. |
