摘要
初步探讨了德令哈地区遭受霜冻害时的低温天气出现与晚、早霜冻之间的相互关系及其规律,得出了较适合该地区主要大田作物气候特点的综合霜冻指标,为今后的霜冻预报服务工作提供理论依据。
The relationship between frequency of the low temperature of frost disaster and early frost injury or late frost injury was studied. The integrated frost indexes adapting to local climate characteristics during growth periods of main field crops were determined by contrast analysis. The results offered a theory foundation for the frost forecast in this region
