摘要
对烟草进行施用钙肥盆栽试验，结果表明，烟苗移栽后35d，土壤交换性钙含量为1142．33mg·kg（Ca7）处理的株高、茎围、叶片数均较多，分别为21．75cm、3．93cm和7．75片·株^-1；烟苗移栽后75d，以Ca7处理的株高、茎围、最大叶长和最大叶宽均较多，分别为76．70cm、5．37cm、37．67cm和17．00cm。随着土壤交换性钙含量增加，烟株的生育期相应推迟2～7d。成熟期烟株的烟叶和烟根干物质重以Ca7处理的最高，分别为50．83g·株^-1和15．13g·株^-1。因此，在本试验土壤条件下，土壤交换性钙含量为1142．33mg·kg^-1（Ca7）处理烤烟若干生长发育指标较好。
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 mg · kg^-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, 37.67em 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 mg · kg^-1 level were found to be better than the control.
