In order to study the relationship of tobacco soil nutrients and chemical indicators, principal component analysis and stepwise regression analysis were used to establish the relation model between soil nutrients and tobacco quality. In the first, discussing the correlation of soil nutrients and the major tobacco chemical composition; Then using principal component analysis to analyze the impact of factors of the leaf chemical indicators eliminated the intrinsic link and repeat information between properties, and extracting the principal component which strong influence on the chemical composition of tobacco; And finally stepwise regression analysis was used to established the equation between soil nutrients and tobacco chemical components.
