不同采收方式和成熟度对上部烟叶烘烤质量的影响

摘要

Effects of different picking methods on single upper leaf weight , grade of tobacco leaf ,appearance quality of leaf and chemical components of flue-cured tobacco was studied. The results showed that the method of picking 4~6 upper leaves with stem together could increase inherent quality of the four picking ways ,one time harvest ways could increase the tobacco leaf output ,because the leaf obtained some material supplements from the stem during the flue-cured process ,own contents consumption of materials were less.One time harvest ways had certain function on enhancing the upper leaf flue-cured quality .The apperance quality ,physical characteristic ,chemical components of one time harvest leaf were better than other harvest ways. Every characteristics of the conventional harvest leafs was better than ring cutting leafs and was inferior than the one time harvest leafs.Ring cutting treatment was inferior than the other two ways.%研究了不同采收方式和成熟度对烤烟上部烟叶单叶重、烟叶等极、烟叶外观质量、烟叶物理特性和烟叶化学成分等的影响，结果表明：在4种采收方式中，烟叶烘烤质量在总体上以一次性采收（带茎或不带茎）的最好，一次性带茎采烤能增加烟叶的产量，可能是因为叶片在烘烤过程中得到了茎杆中的一些物质补充，自身内含物质消耗较少；一次性采烤对提高上部叶烘烤质量具有一定的作用；一次性带茎采烤的烟叶的外观质量、物理特性、化学成分也均优于其他采收方法。常规采收的次之，常规采收的烟叶的各种特性和成分优于环割处理的烟叶，但比一次性带茎采烤的较差。环割处理的烟叶与前两种采收方式采收的烟叶相比较差。
