【摘要】：以鹤壁市农业科学院选育的“永优”系列玉米品种国审浚单20、国审浚单29、鄂审浚单509和陕审浚单3136为例,采用4个品种参加区域试验和2014年地理分期播种试验的数据,以及同期对应站点的气象资料,自播种起以10 d为1个周期,通过数理统计分析影响黄淮海地区“永优”系列玉米产量的气象因子,进而选取气候敏感性因子作为关键指标进行区划。结果表明:“永优”系列玉米产量随品种的更新逐渐增加。各周期日照时数、平均气温、最高气温、最低气温和相对湿度对浚单20、浚单29、浚单509和浚单3136产量的影响趋势基本上相同,但在各期的影响上略有差异。浚单20的敏感系数较小,适应性较好;浚单3136的敏感系数较大,适应性较差,容易受到气象因子的影响,而浚单29和浚单509的适应性居中。“永优”系列玉米品种在黄淮海平原(北部除外)都适宜种植;浚单20、浚单29和浚单509对黄淮海地区的气候因子不太敏感,最适宜面积较大;浚单3136对黄淮海地区的气候因子较为敏感,受气象因子波动的影响较大,最适宜面积相对较小。
[Abstract]:Taking the "Yongyou" series maize varieties Guosheng Jundan 20, Guosheng dredging list 29, Esheng Jundan 509 and Shaanzhuangdan 3136 selected by the Academy of Agricultural Sciences of Hebi City as examples, the data of 4 varieties participating in the regional trials and the geographic sowing trials in 2014 were used. And the meteorological data of the corresponding stations in the same period, taking 10 days as a cycle from sowing time, through mathematical statistical analysis, the meteorological factors affecting the yield of "Yongyou" series maize in Huang-Huai-Hai area were analyzed. Then the climate sensitivity factor is selected as the key index for regionalization. The results showed that the yield of "Yongyou" series maize increased with the variety renewal. The effects of sunshine hours, mean air temperature, maximum temperature, minimum temperature and relative humidity on the yield of single 20, single 29, single 509 and 3136 were similar, but there were some differences in each period. The sensitivity coefficient of Jundan 20 is smaller and the adaptability of Jundan 3136 is better, and the sensitivity coefficient of Jundan 3136 is larger and the adaptability is poor, which is easy to be affected by meteorological factors, while the adaptability of Jundan 29 and Jundan 509 is the middle. "Yongyou" series maize varieties are suitable for planting in Huang-Huai-Hai Plain (except in the north), Jundan 20, Jundan 29 and Jundan 509 are not sensitive to climate factors in Huang-Huai-Hai area, and the most suitable area is larger. Jundan 3136 is sensitive to climatic factors in Huang-Huai-Hai area, which is influenced by the fluctuation of meteorological factors, and the most suitable area is relatively small.
