| 摘 要： | 2009年黄淮海夏玉米区部分地区玉米发生大面积倒伏,造成一定幅度的减产,本文以当地主栽品种郑单958为材料,对倒伏后不同层面子粒的灌浆特性进行比较分析,结果表明,上层植株具有灌浆速率快、灌浆持续时间长、子粒含水量较低、脱水较快等特性,而下层植株子粒灌浆速度慢,持续时间短、子粒含水量较高、脱水较慢,在同样倒伏情况下上层层面减产幅度较小。

| Abstract: | In 2009 a large area of the Huanghuaihai Summer Maize Region had a serious lodging,resulting in considerable yield reduction.The present study used Zhengdan 958,a major maize hybrid in this region,to analyze grain filling characteristics after lodging.The results showed that the upper part of plants had a fast filling rate and long duration filling characteristics while the lower part of plants had slow grain filling and short duration. |
