留叶数对烤烟K326产量和化学成分的影响

为促进烤烟K326产量和质量协调和最优化,以烤烟品种K326为材料,于2014年4-8月研究了留叶数对烤烟农艺性状、经济性状、化学成分的影响,3个处理留叶数分别为18、20、22片。结果表明：随留叶数增加,株高增加,茎围和节距降低,上等烟比例增加,但单叶重并不呈现一定的规律;综合考虑,留叶数22片/株较适宜,产量高,能获得较高的产值,可以考虑在生产上推广应用。...

In order to promote the coordination and optimization of yield and quality of K326,during April to August of 2014,a field experiment was employed to study the effects of apparent leaf number on the agricultural property,economic character and chemical components of flue-cured tobacco variety K326. The remained leaves of three treatments were 18,20 and 22 blades,respectively. The results showed that with the increase in the number of remaining leaves of flue-cured tobacco variety K326,the stem length gradually was increased,but the stem girth and node span was decreased,while the single weight of leaf did not show certain rules. The treatment of remaining 22 leaves per plant can get a high yield and production value,so it can be considered to be applied in production.
