Abstract：Exploring the difference of mineral nutrition contents in leaves and roots of flue-cured tobacco during growing period could help to provide the basis for flue-cured tobacco cultivation measures under different soil texture conditions .Sandy loam ,silty clay ,loam soil and sand culture were selected to develop this experiment with flue-cured tobacco breed NC89 in 2012 .The results showed that the contents of Mg ,Fe ,Cu ,Zn in leaves and Mg ,Fe ,Cu in roots of flue-cured tobacco were influenced by different textural soils .Ninety days after tobacco transplanting ,the contents of N ,P ,K ,Ca ,Mg ,Fe ,Zn in leaves and Mg ,Cu in roots were higher in silty clay treatment .The con-tents of N ,P ,K ,Zn in roots were higher in loam soil treatment ,but lowest in sandy loam treat-ment .While the content of Fe ,Ca in roots were highest in sandy loam treatment .The variations of mineral nutrition content in leaves and roots were different except potassium during the growing period .Therefore ,tobacco mineral nutritional status can be regulated through supply of nutrients under different soil texture conditions .
