| 摘 要： | 采用灰色关联度分析了安阳夏玉米生育期间主要气象要素与夏玉米产量的关系，明确了当地夏玉米产量在年度间的差异主要以积温为主导因素，不同生育期中的气候因素以拔节-乳熟期的光照和降水量对产量影响最大，而乳熟-成熟的降水量对产量的影响程度最弱。

| Abstract: | Anyang main climatic factors and summer corn yield in the summer corn growing period are analyzed by gray correlation method. The dominant factor of Anyang county summer corn yield annual contrast is the accumulated temperature. The climatic factors in different growing periods, especially the sunlight and precipitation of elongation-milky stage, make the greatest impact to yield, but the precipitation of milky-mature stage makes the weakest impact. |
