In order to evaluate the soil nutrients of cigar tobacco planting lands, soil nutrients of 162 soil samples sampled from cigar planted fields in Ruili City of Dehong had been surveyed and evaluated. Soil nutrients including organic matter, total nitrogen, alkali hydrolyzed nitrogen, available phosphorus, available potassium, available sulphur, available manganese, available zinc and available boron were tested and the cloud model algorithm had been used to evaluate the nutrients suitability of cigar tobacco planted soil. The results showed that nutrients suitability of cigar tobacco planted soil appeared at high level, the Ex(expectation) of the parameters simulated by the cloud model reached 0.706 9. In the tobacco soils, the contents of available phosphorus and available potassium were abundant, while the content of alkali hydrolyzed nitrogen showed a little bit low; trace elements were at high level, while available sulphur, available zinc and available boron showed obvious cloud droplet status; and the distribution of soil nutrients showed slightly more randomness and fuzziness(entropy and hyper entropy). In conclusion, the fertilization strategy for cigar tobacco producing area in Dehong could be carried out by improving the available nitrogen application, meanwhile the boron fertilizer should be improved in some areas to ensure nutrient balance.
