摘要: 为给科技人员正确应用烤烟叶面积相关指标提供参考依据,在现行优质烟生产条件下,针对14个基因型烤烟叶面积指数最大时期的关联指标进行研究。结果表明:采用叶形纸称重法测算烤烟叶面积校正系数是完全可行的。田间单株叶面积在1.84~2.90 m2,平均为2.08 m2;最大叶面积指数在3.07~4.83,平均为3.47。不同基因型烤烟之间,叶面积校正系数和最大叶面积指数差异较大,不宜采用某一常数值进行机械套用,而应针对特定品种进行探索。

Abstract: To provide scientific reference for correctly applying flue-cured tobacco LAI and its relevant technical parameters, 14 genotypes of flue-cured tobacco in their maximum LAI period were studied under the current quality tobacco leaves production in this paper. The results showed that it was completely feasible to use leaf-shape paper weighing method to quantify the leaf area correction coefficient of flue-cured tobacco. An average value of leaf area per plant in the field was 2.08 m2, and their ranges were from 1.84 m2 to 2.90 m2. An average value of the maximum leaf area index was 3.47, and their ranges were from 3.07 to 4.83. Leaf area correction coefficient and the maximum LAI had large differences among different genotypes of flue-cured tobacco. It is appropriate to select a parameter for practical application by a specific variety, not use a constant value.
