| 摘 要： | 运单系列玉米品种是指由山西省农科院棉花研究所育成的晋单39号、晋单46号、运单19、运高油1号等玉米单交种,这些品种与其他品种比较具有耐寒性差、耐高温性好、生长速度快、叶片光合效能强、产量突出等特性。在栽培管理上要求推迟播种时间;适当增加种植密度;提早施肥,一促到底;补施灌浆肥。提倡在易发生持续高温天气的地区使用运单系列玉米品种。

| Abstract: | Maize single cross hybrids Yundan series of Jindan 39,Jindan 46,Yundan 19,Yungaoyou 1 etc,are bred by Cotton Research Institute,Shanxi Academy of Agricultural Sciences.Compared with other maize hybrids,they are characterized by poor cold hardiness,good high temperature tolerance,fast growth,high photosynthetic efficiency of leaves and high yield etc.Their cultivation practices are as follows.Sowing date should be postponed in the early spring,planting density should be increased properly,and fertilizers are applied ahead.At filling stage,fertilizer application should be supplemented.It is recommended that maize hybried Yundan series be used in easy continuous high temperature areas. |
