| 摘 要： | 以郑单958为材料，在67 500株/hm2和82 500株/hm2两个种植密度水平下，以常规等行距种植方式为对照，设置3种不同缩行宽带种植方式（3行一带、4行一带、5行一带），进行连续两年比较研究。结果表明，缩行宽带种植方式增产显著，其中，3行一带种植方式高密度水平下产量最高。通过Logistic方程拟合，缩行宽带各种植方式中，高密度下灌浆时间持续期均值较对照等行距方式增加1.2～10.2 d。无论是高密度还是中等密度条件下，3行一带种植方式平均灌浆速率（R）、最大灌浆速率（Rmax）、最终百粒重及渐增期灌浆速率（R1）均较高。因此，3行一带缩行宽带种植方式子粒灌浆特性较优。

| Abstract: | A field experiments involving four planting patternsthree-row strip, four-row strip, five-row strip and a conventional uniform row spacing pattern(the control)] under two plant densities(67 500 plants/ha and 82 500 plants/ha) with cultivar named Zhengdan958 were conducted in 2011 and 2012. The results showed that the grain yield was significantly increased by strip planting patterns in both years. Based on the Logistic equation fitting, the duration of grain filling increased by 1.2-10.2 days in strip planting patterns, compared with control, and the average filling rate(R), maximum filling rate(Rmax), the filling rate at gradual increasing(R1),100-grain weight were all highest under the three-row strip planting pattern under both densities. Therefore, three-row strip planting pattern could be suggested for enhancing grain yield of summer maize in the local area. |
