摘要:分析了云南省曲靖烟区气候因素、土壤3 养分状况及所产烟叶化学成分特点,结果表明:曲靖烟区具有无霜期长,大于 10 ℃
积温高,大田期气温适宜,日照充足,降雨充沛等特点。植烟土壤养分含量存在较大的变异; pH 值适宜,有机质含量丰富,具有较
强的保肥能力;氮、钾含量较高,速效磷含量丰缺各半;多数中微量元素含量丰富,但钙镁比、钾钙比不合理,影响了烟株对镁和钾
的吸收利用,且有效硼、有效钼含量偏低,应注意追施硼肥和钼肥。曲靖烟叶两糖含量较高,总氮、烟碱含量适中,钾、氯含量不高,
组成比例协调,基本符合优质烟叶标准。

Abstract:Meteorological factor, status of soil nutrients and ponents of flue cured o leaveswere analyzed in Qujing, Hunan
Province. The results indicated that: Qujing o growing areas had a long forst free period, high accumulated temperature of ≥10 ℃, the
suitable average temperature, the amp le sunlight, the sufficient p recip itation. The nutrient content of the soil showed a big variation in l
