摘要: 分析了四川省达州烤烟区基本自然条件、气候因素、植烟土壤养分状况和所产烤烟的质量特点,结果表明:该烟区具有生态优越、气候温和、降雨充沛、光照充足、热量较为丰富、无霜期长等特点,地貌类型为山地、丘陵,土壤主要为紫色土、水稻土等,多呈微酸性,有机质含量适中,土壤氯离子含量低,多项指标均达到了烟草适宜类型的环境条件;多数养分含量适宜或丰富,但区域间肥力差异较大,土壤氮、磷、钾含量偏低,锌含量不足,缺硼较严重,施肥上应注意稳施有机肥与氮肥,加大磷肥、钾肥的用量,适当补充锌、硼元素,并加强分类指导。达县烤烟以橘黄为主,叶片结构疏松,厚薄适中,外观品质较好,化学成分含量较适宜,比例协调,香型风格为中间香型,配伍性强,工业可用性强,感官质量较好。

Abstract: The climate factors, soil nutrient status and the quality characteristics of flue-cured tobacco leaves in Sichuan Province Dazhou were analyzed. results showed that,Dazhou flue-cured tobacco growing areas was humid subtropical monsoon climate, had the characteristics of mild climate, moderate rainfall, adequate light, heat is rich, air humidity. It showed that the ecological conditions of Dazhou flue-cured tobacco growing areas were suitable for the growth of tobacco. The soil in Sichuan Province Daxian was suitable, organic matter content in the most suitable medium, the CEC of soil was suitable, most of nutrition element content in soil were rich or appropriate, natural selenium in soil was rich, phosphorus and potassium were insufficient, zinc was lack, boron was extreme lack. The physical characteristics and chemical composition were suitable, the style characteristic of flue-cured tobacco was obvious, sensory quality was better.
