摘要：

为玉米品种合理引种提供参考，采用不同玉米品种在南北纬度不同试点进行生态试验，探讨玉米生育时期与纬度的关系。结果表明，在海拔基本一致的前提下，低纬度种植的玉米成熟期明显提前，播种～成熟、出苗～成熟时间均缩短；纬度对玉米营养生长的影响大于生殖生长；玉米全生育期、营养生长时间、生殖生长时间与纬度存在正的线性关系，同一年份的回归系数相近，不同年份间差异较大。

Abstract:

In order to provide reasonable references to introduction of maize varieties, we did ecological experiments using different maize varieties in places at different latitude and discussed the relationship between the growth stage of maize and latitude. The results show: under the premise of basically the same altitude, maize at low latitude matures earlier than high latitude obviously; the time of both sowing-to-maturation and emergence-to-maturation is shorter. Latitude has a bigger influence to maize vegetative growth than to reproductive growth. Maize whole growth periods, vegetative growth time and reproductive growth time all has a positive linear relationship to latitude. The regression coefficients are similar in the same year and have great difference in different year.
