英文摘要:

      In this paper the relationship between the temperature and crop yield was analysed and the causes,types,indexes and distribution of low temperature damage on crops were noted. By use the methods of statistical decision and linear programming, suggestions concerning adjustments of crop-variety distribution and variety ratio for avoiding and reducing the cool summer disasters were made.
