摘　　要：在四川省泸州市古蔺县烟草科技示范园开展田间试验,研究几种因素对烤烟不同部位抗拉力值的影响。结果表明,鲜叶重、茎叶夹角、叶长、含水率等与抗拉力值存在二次多项式关系。在一定范围内,烤烟不同部位抗拉力值随鲜叶重增加、叶片长度增加、茎叶夹角增大而增大;超过一定范围后,烤烟不同部位抗拉力值随鲜叶重增加、叶片长度增加、茎叶夹角增大而减小。Field experiments were carried out in Gulin tobacco science and technology demonstration park in Luzhou City,Sichuan Province to study the effects of several factors on the tensile resistance of different parts of flue-cured tobacco.The results showed that fresh leaf weight,stem leaf angle,leaf length and moisture content had quadratic polynomial relationship with tensile resistance.Within a certain range,the tensile resistance values of different parts of flue-cured tobacco increased with the increase of fresh leaf weight,leaf length and the angle between stem and leaf;when beyond a certain range,the tensile resistance value of different parts of flue-cured tobacco decreased with the increase of fresh leaf weight,leaf length and stem leaf angle.
