| 摘 要： | 本文阐述了对秦皇岛地区平原春玉米的产量与主要气象因素(温、光、水)相关关系的分析,明确了影响玉米产量的关键气象因素及影响产量的关键时期;通过对本区两个玉米主栽品种的生长发育规律的研究,提出了高产栽培下的适宜指标;还阐述了采用多元二次回归正交旋转组合设计方法,以影响玉米产量的主要农艺措施为决策变量,得出的相应的数学模型,及筛选出的亩产500kg以上产量水平的优化农艺措施组合。

| Abstract: | The relationships between corn yield and main meterological factors such as temperature, light and water in the plain of Qinhuangdao district were analysed and the key factors affected yield and the key stage were determined. By studying the law of gnowtn of two main cultivars the available index of growth for high yield was put out and a mathematic modle was obtained by multiveriate quadratic regression, orthognal design of rotational combinations with the main agronomical factors affected corn prcdution as determinants and the optimum combinations of agronomical practices were selected out for yield level beyond 500kg/mu. |
