A pot experiment was conducted to determine the effect of the available calcium content in soil on the growth of flue-cured tobacco.The result indicated that after tobacco seedlings were transplanted for 35 days,the height,stem girth and number of leaves of the tobacco plants treated with Ca7(1142.33 mgkg-1) were improved reaching 21.75cm,3.93cm and 7.75 piece/plant,respectively.After 75 days,the height,stem girth,maximum leaf length and minimum leaf length of the treated tobacco plants were found to be 76.70cm,5.37cm,37.67cm and 17.00cm,respectively.The growth and development period was delayed 2-7 days with the addition of calcium.The dry matters in the leaves and roots of the treated tobacco plants in autumn reached a peak value of 50.83g/plant and 15.13g/plant,respectively.Under the experimental conditions,the growth and development of the flue-cured tobacco in soil with Ca7 at 1142.33 mgkg-1 level were found to be better than the control.
