摘　　要：A study on change of contents and distribution of the rare earths in roasted tobacco plant and effects on chemical composition in roasted tobacco leaves of the rare earths was reported.The results indicate that the content of rare earths in tobacco plants distribute mainly in leaves;spraying the rare earths can promote the plant to absorb the soluble rare earths in soil;the plant gains the rare earth mainly from soil;the rare earths have good effects on the quality of roasted tobacco leaves.A study on change of contents and distribution of the rare earths in roasted tobacco plant and effects on chemical composition in roasted tobacco leaves of the rare earths was reported.The results indicate that the content of rare earths in tobacco plants distribute mainly in leaves;spraying the rare earths can promote the plant to absorb the soluble rare earths in soil;the plant gains the rare earth mainly from soil;the rare earths have good effects on the quality of roasted tobacco leaves.
