With the consideration of our climate characteristics and grapevine growth needs,and based on the comparison and analysis of several atmospheric moisture content indexes,the authors considered that the dryness index(DI=ET_C/P) in grapevine growth season(April 1-September 30) could be a proper atmospheric moisture content index for the climatic zoning of grapevine cultivation in China.
