摘　　要：对河南洛宁烟区的植烟基本条件、气候因素、土壤养分状况以及所产烟叶的质量特点进行了分析.结果表明:洛宁烟区具有无霜期长,大于10℃积温高,大田期气温适宜,光照充足,且雨热同步等特点;植烟土壤速效氮含量、速效磷和速效钾含量适中,交换性镁含量较高,但有机质、有效锌和有效硼含量缺乏;烟叶外观质量较好,香气量较足、香气质较好,燃烧性强,填充力较高,内部化学成分含量适宜,但协调性与津巴布韦烟叶相比尚有差距.The basic conditions, climatic factors, soil nutrients and quality of flue-cured tobacco leaves inLuoning tobacco-growing area were analyzed. The results showed that Luoning tobacco-growing areas hada long frost-free period, suitable temperature, 〉10 ℃accumulated temperature, sufficient sunlight, therainfall and heat had the same changes. In the soil of this area, the content of available nitrogen was low,the contents of available phosphorus and available potassium were suitable, the content of exchangeablemagnesium was high, but the contents of available zinc：, organic material and available boron were low orlack. Tobacco leaves of Luoning had good appearance quality, full aroma quality, good fragrance, strongcombustibility, higher filling power, reasonable chemi：al component. However, the coordination of the chemical composition in tobacco leaves was inferior to the high quality Zimbabwe tobacco.
