Abstract: Days available for tobacco-growing in fields as the basis were provided for the arrangement of its rational distribution and production technical measures. We used the daily data of 84 meteorological stations in Guizhou from 1961 to 2010 to analyze the initial temperature and final temperature for tobacco growing on the GIS platform to determine its available days in field. The results showed the days available for tobacco growing in field varied largely with locations, which reduce with the elevation. According to the length of time, geographical distribution and climatic characteristics, the days available were divided into four types of areas. Apart from the areas above the altitude of 2000 meters, available days in fields can ensure the normal growth for flue-cured tobacco. According to various areas of available days and climate characteristics, use patterns and technical requirements are presented for different types of areas, and arrangement propositions are proposed for the transplanting period and the end of harvest period for all types of areas.
