摘要
[目的]分析玉米杂交种在不同地区的生态适应性。[方法]引用国家东南区玉米品种区域试验参试品种在凤阳和阜南种植的结果,采用对比分析的方法对这2组玉米生育期内所处的生态条件及产量上的差异进行分析。[结果]结果表明,光、温、水是影响玉米产量的主要气象因子,抽雄期前后是对玉米影响最大的时期,应将玉米的抽雄期置于光、温、水三者协调的时段。[结论]该研究结果为玉米杂交种的栽培和推广提供理论依据。
[ Objective ] The purpose of this research was to analyze the ecological adaptation of maize hybrid in different regions. [ Method] Comparative analysis of the results of using this method in which the two groups during the maize growing ecological conditions and yield the differences were analyzed. [ Result] The results showed that light, temperature, water were the main meteorological factors impacting on corn production, in the period before and after tasselling stage was the period having the greatest impact on corn, corn should be placed in the tas- selling stage of light, temperature, water coordination of the three periods. [ Conclusion ] This research will provide the theoretical references for cultivating and popularizing maize hybrid in different regions.
