| Abstract: | with the data of typical late frost injury years, conclusion can be draw that in the past 10years the years winter tending warm is twice as 1980's and the frequency of late frost injury occurs is about 1.88 times than 1980's.when the winter warms, temperature becomes increase quickly in spring and wheat joints up earlier, the frequency that late frost injury happens is about 66.7%. |
