Pond experiment was conducted to study the influences of different sand/clay ratios on the quality characteristics of the flue-cured tobacco. The results showed that: the dry weight accumulation?of flue-cured tobacco was in an order of sandy loam(in texture soil)﹥clay loam﹥clay﹥sandy loam (coarse texture soil), and the treatment of 2/3 sand + 1/3 clay was the best; the single leaf weight in an order of 2/3 sand + 1/3 clay > 1/3 sand + 2/3 clay > 100% clay > 100% sand; generally the visual quality, the balance of the chemical constituents, the contents of the aroma matters and the sensory quality and character of tobacco of the treatment of 2/3 sand + 1/3 clay were the best, thus here 2/3 sand + 1/3 clay could be regarded as the optimal for the form of the quality and character of flue-cured tobacco, with the sand content reaching 50%, the content of dust below 30%, and the clay below 20%.
