摘要
主要对四川会理烟区的植烟气候因素、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:会理烟区具有无霜期长,大田期气温适宜,降雨充沛,光照充足,且雨热同步等特点;植烟土壤pH值适宜,有机质含量较丰富,具有较强的保肥能力,土壤总氮和碱解氮含量高,速效磷、钾含量适中;交换性钙、镁含量较高,有效硫含量丰富,但有效锌、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,香型以清香型为主,燃烧性强,但内部化学成分间的协调性与国外优质烟叶相比尚有差距。
Basic conditions for tobacco growing areas, meteorological factors, status of soil nutrients and quality of tobacco leaves were analyzed in Huili, Sichuan province. The result indicates that, Huili tobacco-growing areas had a long frost-free period, suitable temperature, abundant rainfall, sufficient sunlight, while the rainfall and heat had the same changes, and other meteorological factors. The pH of the tobacco-growing soil was appropriate, the organic material was rich, and it had strong ability to maintenance of soil fertility; the content of total nitrogen and available nitrogen were high, available phosphorus and available potassium were suitable; the contents of exchangeable calcium and magnesium were high, the available sulfur content was rich, but the available zinc content is low, and the available boron content was lack. The appearance quality of the most samples were good, mostly samples had full aroma quality, the fragrance was good （mainly was delicate fragrance）, combustibility was strong, but compared with the high quality import tobacco, the level of the coordination of the chemical composition in tobacco leaves was still lower.
