Abstract: By using the interpretative methods of grey systematic theory and the gradual regression analysis, the relationship between 4 meteorological factors and the main economic properties of cotton were investigated. The results showed: The variation coefficient of illumination hour and temperature to single boll weight and seed index is bigger than that of lint percentage and lint index under the condition of special ecosystem and cultivation in Hunan Province. Temperature and illumination hour are positive to single boll weight and seed index. Rainfall is rarely positive to single boll weight. Rainfall is positive to lint percentage and lint index.
