本文通过３年秋大麦分期播种试验，分析了晚秋气温变化对大麦产量性状的影响，提出在晚秋气候条件下大麦幼德分化（－叶－心－抽穗）和抽穗－成熟期的最适温度时段。并提出利用气候资料，找到最适温度时段的高产的气候环境的方法播种期确定依据。探讨了攀西晚秋气候条件下，大麦的产量潜力。
In this paper, three-year barley sowing seeding experiments were conducted to analyze the effects of temperature changes in late autumn on the yield traits of barley. The optimal temperature period of barley differentiation (leaf-core-heading) and heading-maturing stage was proposed in late-autumn climatic conditions. And put forward the method to determine the sowing date by using climatic data to find the climatic environment with high yield during the optimum temperature period. The yield potential of barley was discussed under the climatic conditions of Panxi in late autumn.
