Research of Climatic Zoning Index System of Red Cartridge Kiwifruit in Guizhou.

The climate data of 84 meteorological stations in Guizhou from 1981 to 2010 was used, including the statistical data of daily precipitation, temperature, sunshine hours, evaporation, frost free period and so on. Using the equations of light and heat coefficient, light and heat index, latitude and temperature index, active accumulated temperature, effective accumulated temperature, aridity index, and arid-wet index, the red cartridge kiwifruit zoning index of Guizhou was analyzed and studied. The results showed that the zoning index system for the climatic characteristics of Guizhou mountainous area must be established in order to realize the variety regionalization of red cartridge kiwifruit in Guizhou mountainous area, and ten climatic factors were taken as dimatic zoning indexes of red cartridge kiwifruit planting, including active accumulated temperature, effective accumulated temperature, annual average temperature, average temperature of July, light and heat coefficient, light and heat index, latitude and temperature index, frost free period, aridity index and arid-wet index. These indicators were giving a comprehensive evaluation for climate suitability conditions of red cartridge kiwifruit planting, and providing the scientific and reasonable basis for the promotion planting of red cartridge kiwifruit in mountain area of Guizhou.
