| 摘 要： | 通过播种期试验，研究了不同生态条件对玉米品种郑单22的生长发育和产量的影响。结果表明，在河南夏播条件下，随着播种期的推迟，郑单22的产量逐渐下降，穗行数、行粒数和千粒重均逐渐降低，生育进程加快，叶面积指数最大值、干物质积累量逐渐减小，但6月15日以前播种的差异不大。适宜生态条件为：全生育期积温2835.1~3038.2℃，至2560.4℃产量严重下降；全生育期日均温度为25.3~25.7℃，至25.1℃产量严重下降；全生育期光照484.2~630.4h，至420.7h产量严重下降；全生育期日均光照为4.3~5.3h；至4.1h产量严重下降

| Abstract: | The influence of different ecological condition on growth and yield of corn variety Zhengdan 22 was studied through sowing-date experiment at Ayang city. The yield, ear row number, and row grain number dropped, the growing process quickened , the maximum leaf area index and dry matter accumulation declined, along with the postponement of summer sowing, The ecological adaptability for high yield of Zhengdan 22 was that whole growing accumulated temperature was 2835.1~3038.2℃ and whole growing daily mean temperature was 25.3~25.7℃, whole growing accumulated sunshine hour was 484.2~630.4h and whole growing daily mean sunshine hour was 4.3~5.3h. |
