2011—2012年对云南8个烤烟有机种植区域初烤烟叶进行取样分析，研究不同产区有机种植方式下烟叶常规化学成分及安全性特征，为制定科学的烤烟有机种植技术提供依据。结果表明：云南8个生态区的有机烟叶，产区间常规化学成分差异较大(CV 为8.65%~22.79%)，区域特征可聚为4类。下部烟叶常规化学成分基本符合标准要求；中、上部位烟叶水溶性总糖含量和糖碱比值整体偏高，总氮和钾离子含量及氮碱比值整体偏低，降低了烟气协调性。烟叶中重金属铅、镉、砷、汞、铬含量均低于标准下限，无农残检出，烟叶安全性较好。可见，烤烟有机种植后期应合理提高氮素和钾素养分供应水平，以满足烟株的关键养分需求，改善有机烟叶内在化学成分的协调性。

Conventional chemical composition and security features of organic flue-cured tobacco leaves from eight different planting areas in Yunnan province were analyzed based on the data from 2011 to 2012. There was a higher variation in conventional chemical composition of flue-cured tobacco leaves among different ecological areas( CV was between 8. 65% —22. 79% ). Four tobacco leave types were grouped according to the regional characteristics. Down stalk tobacco leaves agreed with the standard;mid-dle and upper stalk tobacco leaves had higher water soluble total sugar content and sugar alkali ratio,but lower total nitrogen,potassium content and alkali nitrogen ratio,with less harmony. The contents of heavy metals,lead,cadmium,arsenic,mercury,chromium were below the standard limit,and no pesticide resi-dues were detected,so the security of tobacco leaves could be concluded. A reference was provided for es-tablishing scientific organic flue-cured tobacco planting techniques. It was suggested that appropriately rai-sing the level of nitrogen and potassium supply during the later period of tobacco organic cultivation was necessary to satisfy the demands of key nutrients for tobacco growing and improve the conventional chemi-cal composition harmony of organic tobacco leaves.
