摘　　要：【目的】本试验研究了土壤含水量和光照强度对不同留叶数下烤烟叶片柔韧性的影响。【方法】通过温室大棚试验,设置不同留叶数(18、20、22片)、不同土壤水分含量(40%以上、20%以下)和不同光照强度(遮阴、不遮阴)3个处理对烤烟K326各部位叶片柔韧性进行研究。【结果】在留叶数目一定的情况下,土壤含水量越小,光照越不足,烤烟的生育期越短,长势越差,烤烟叶片的柔韧性越低,越容易发生断叶现象。【结论】当烤烟处于易发生断叶现象的环境条件中时,适当减少有效的留叶数可以在一定程度上提高叶片的柔韧性,从而达到预防断叶现象发生的目的。【Objective】The effects of soil water content and light intensity on the leaf flexibility of flue-cured tobacco leaves under different leaf number were studied.【Method】Through the greenhouse experiment set,the number of leaves( 18,20,22),different soil moisture content( more 40 % or less 20 %),and different light intensity( shading,no shading),the leaf flexibility of all parts of flue-cured tobacco K326 was studied. 【Result】In the case of a certain number of leaves,the lower the soil water content was,the less the light was,the shorter the growth period of flue-cured tobacco was,the worse the growth the lower the flexibility of the flue-cured tobacco leaves was,and the more prone to the phenomenon of broken leaves was. 【Conclusion】When the flue-cured tobacco was in the environmental condition with the phenomenon of broken leaves,it was necessary to reduce the effective leaf number to improve the flexibility of the leaves to a certain extent so as to achieve the purpose of preventing the occurrence of broken leaves.
