摘要
针对百色北部烟区近几年来上部烟叶烟碱含量较高而可用性较低的问题,通过分析上部烟叶质量和可用性之间的关系及影响上部烟叶质量的因素,从品种、施肥、育苗、打顶留叶、后期水分管理、打顶留叶数、上部叶采收成熟度、采收方式及烟叶调制等方面,提出降低上部叶比例、提高上部叶可用性的措施。
Aiming at the proclems of higher leaf nicotine and lower usability at upper part of tobacco in Northern Baise recent years,an analysis on relationship between leaf quality and usability,and the factors impacting leaf quality was conducted from aspects of variety,fertilization,seedling culture,top-cut leaf-remaining,water management in late period,leaf-remaining number after top-cut,leaf-harvest maturity,leaf-picking methods and leaves processing.Some measures of reducing the proportion of upper leaf and increasing their usability were put forward.
