摘　　要：为探究重庆地区植烟生态环境和技术措施下烤烟K326最优的留叶数,通过采取不同留叶数处理,分析各个处理水平下K326的农艺性状、经济性状和化学成分含量。结果表明,在重庆丰都的生态环境和技术措施下K326留叶数为18~20片时,综合农艺性状表现最好,能够达到较高的产值,中上等烟叶比例提高,调制后烟叶化学成分含量适宜且比例协调。To explore tobacco K326 optimum apparent leaf number under the ecological environment and the technical measures in Chongqing city,by adopting different apparent leaf number treatments, the agronomic traits,economic characters and chemical components content of K326 various treatments were compared and analyzed. The results showed that,under the ecological environment and the technical measures in Chongqing city,the apparent leaf number of K326 ranged 18 to 20 per plant,the comprehensive agronomic traits performed the best,the higher output could be achieved,and the proportion of middle and high grade leaves was increased,the chemical component content of tobacco was suitable with harmonious proportion after modulation.
