In this paper, the appearance quality tobacco from Nanping tobacco-growing areas in central, sensory Smoking Quality, five aspects of the chemical composition, species and ecological factors, the relationship of the Nanping smoke characteristics of flue-cured tobacco quality and ecological factors analysis system. And discuss the relationship between the chemical composition and quality of tobacco leaves, clear Nanping Tobacco Leaf Quality chemical composition as well as the main ecological factors affecting Nanping specialty tobacco, provides a theoretical basis for the production and management of Nanping quality tobacco smoke, The results are as follows: the Nanping smoke zone climate conditions characterized Shaowu, Wuyishan, shiny (I climatic zones), belonging to tobacco-growing areas of the northern part of Nanping City, the main features as follows: low average monthly temperature, monthly average sunshine hours than The average monthly relative humidity moderate average monthly rainfall. Jianou, Shunchang, Jianyang (the first Ⅱ climate area), the central smoke District Nanping City, the main characteristics: the monthly average temperature is moderate, the monthly average sunshine hours more, the monthly mean relative humidity, monthly average rainfall is low. Governance, the Songxi and Pucheng (first-Ⅲ climate region), belong to the Nanping city in southern tobacco-growing areas, the main features are: higher monthly average temperature, monthly average sunshine monthly average relative humidity is low, monthly average rainfall is moderate. Yanping (located in Nanping City, the southern-most) alone for a subset of the mainly to the the Yanping monthly average temperature, monthly average sunshine hours and the average monthly rainfall Shaopian more. Nanping tobacco-growing areas flue-cured tobacco chemical composition and sensory evaluation of the quality of the relationship between conventional chemical composition, total sugar, reducing sugar, sugar alkali ratio, total nitrogen, volatile alkali tobacco smoking quality greater impact, the relevance of the significant or very significant level. , Total nitrogen, volatile alkali on smoking quality showed negative effects, total sugar, reducing sugar, sugar alkali ratio showed a positive effect. Pyridine caused fragrant substances, bitterness, malic acid, chlorogenic acid, 2 - methyl-tetrahydrofuran, succinic acid, linolenic acid, dimethyl dibutyl phthalate smoking quality large positive effect, and the relevance of a significant or very significant level. The phenylacetaldehyde, neophytadiene, α-cancellous ester alcohol acid, butyric acid, valeric acid, geranyl acetone, benzyl alcohol, phenethyl alcohol, β-damascenone, giant beans gestrinone, 2 - phenylethyl acetate the negative effects of smoking quality and relevance of significant or very significant level. 3. Comparative analysis of of Nanping smoke different cultivars with different fertilization measures the Nanping middle of the different varieties of the chemical composition of tobacco differences, specific performance: Variety CB-1 and red total sugar, reducing sugar content and sugar base than to be significantly higher than the clouds 85 clouds 87 and K326; variety CB-1 and red large total plant alkaloid, total nitrogen content was significantly lower than the clouds 85 clouds 87 and K326. Cases do not consider producing areas of ecological environment conditions, the quality of the sample status and representation, on the whole, the effect of organic fertilizer with potassium nitrate, potassium sulfate mixed application significantly better than the simple application of organic manure; application of cow dung Central the C3F tobacco samples quality of sensory evaluation grade application of cake, chicken manure. 4. The relationship of Nanping tobacco-growing areas of ecological factors and quality of tobacco of Nanping smoke District, the greatest impact of climate factors on the chemical composition of tobacco: March average rainfall, average temperature in March and April the average number of hours of sunshine in April average temperature, average rainfall in April, May sunshine hours, climatic factors in the survey, in March, April, the average number of hours of sunshine and average temperature, average rainfall in June and July average sunshine hours a positive effect on the role of rainfall in March, the March average relative humidity of the role of the negative effects. Alkaline hydrolysis in soil nutrients nitrogen, total nitrogen the sugar base than conventional tobacco chemical composition, total nitrogen, total sugar was a positive effect, alkali ratio of nitrogen, total nitrogen, reducing sugar showed a negative effect; organic matter in soil nutrients, exchangeable magnesium, effective sulfur, water-soluble chlorine alkali than conventional tobacco chemical composition of sugar, total nitrogen, total sugar showed a negative effect of alkali ratio of nitrogen, total nitrogen, reducing sugar was a positive effect.
