摘要：以玉米（Zea mays L.）永优系列4个品种为材料，根据2014年和2015年黄淮海地区12个代表站点田间分期试验的生育期资料和同期气象观测资料，分析了黄淮海地区永优系列玉米4个品种的光温适宜范围和差异，并进行了区划，以期为不同玉米品种在黄淮海地区的种植和选育提供参考。结果表明，黄淮海地區的光温条件基本上能够满足永优系列玉米品种生长发育的需要。较适宜黄淮海地区日照时间的适宜范围面积由大到小依次为浚单20、浚单29和浚单509、浚单3136；日照时间出苗-拔节期的整个黄淮海地区都为适宜，拔节-抽雄期南部和北部为主要适宜区，抽雄-成熟期仅河北省和山东省的北部为较适宜区。≥0 ℃积温的适宜范围面积由大到小依次为浚单20、浚单29、浚单3136、浚单509；≥0 ℃积温出苗-拔节期浚单20、浚单29的适宜范围最大，浚单509没有适宜范围，拔节-抽雄期浚单20的适宜范围面积最大，浚单29的次之，浚单3136的面积最小，抽雄-成熟期的4个品种基本相同，以适宜为主。日最高、最低气温的适宜区主要在中西部，各品种间差异较小。整个生育期，黄淮海地区永优系列玉米品种光温适宜区从西南往东北逐渐减少，适宜面积浚单20的最大，浚单29次之，浚单509和浚单3136较小。

Abstract： Taking 4 Yongyou series maize （Zea mays L.） varieties as material，the different stage sowing experiment was conducted in 2014 and 2015 at 12 stations of Huang-Huai-Hai region. Based on growth periods data and observed meteorological data，the differences of light-temperature suitability between 4 Yongyou series maize varieties in Huang-Huai-Hai region were analyzed，and the light-temperature suitability division were finished. The results showed that the sunshine and temperature of Huang-Huai-Hai region was basically suit for 4 Yongyou series maize varieties growth. The sunshine duration suitability of Yongyou series maize varieties were Xundan 20，Xundan29 and Xundan 509，Xundan 3136 in descending order. The Sunshine durations of all the Huang-Huai-Hai region were suitable during emergence-jointing period， the northern and southern of Huang-Huai-Hai region were manly suitable areas during jointing-heading period， and only the northern of Hebei and Shandong province were sub-suitable areas during heading-maturity period. ≥0 ℃ accumulated temperature suitable areas were Xundan 20，Xundan 29，Xundan 3136 and Xundan 509 in descending order；during emergence-jointing period， Xundan 20 and Xundan 29 suitable areas were largest and Xundan 509 had none；during jointing-heading period， Xundan 20 suitable area was largest，Xundan 29 was second，Xundan 3136 was smallest；during heading-maturity period，the 4 varieties were similar and suitable areas were mainly. The suitable area of the highest and the lowest temperature were mainly in the middle and west part of Huang-Huai-Hai region，and the differences of 4 varieties were less. In the whole growth period，the light-temperature suitable areas of 4 Yongyou series maize varieties in Huang-Huai-Hai region were decreased from southwest to northeast. The suitable area of Xundan 20 was the largest，Xundan 20 was the second，Xundan 509 and Xundan 3136 were smaller.endprint
