为降低烟叶中的重金属含量，提高烟草及其制品的安全性，采用盆栽试验的方法，研究了不同种类的有机肥与无机肥配施对烤烟生长发育及重金属含量的影响。结果表明，在施氮量相同条件下，有机肥与无机肥配施的处理在后期促进烤烟的生长发育，提高烟叶生物量；商品有机肥与无机肥配施显著降低烟株铅含量，烟叶铅含量比 CK 减少了43.83%；农家肥与无机肥配施显著降低烟株镉含量，烟叶镉含量比 CK 减少了33.29%；各处理烤烟不同器官对铅、镉吸收与分配分别为根＞叶＞茎与叶＞茎＞根，根系铅分配率达46.48%～60.91%，烟叶镉分配率为78.03%～81.39%。

In order to decrease the lead and cadmium contents in tobacco leaves, and improve the safety of tobacco and tobacco products, pot experiments were conducted to study the effects of different types of organic fertilizers on the growth and the heavy metal contents of the flue-cured tobacco. The results showed that under the same condition, applying organic and inorganic fertilizer remarkably improved plant height, maximum leaf area and biomass at late growth stage. Compared with the CK, The application of commercial organic fertilizer significantly decreased leaf lead content by 43.83%, and application of farmyard manure significantly decreased leaf cadmium content by 33.29%. The content of lead in tobacco plants varied in the sequence of roots>leaves>stems, while cadmium followed the sequence of leaves>stems>roots. 46.48%~60.91%of lead was found in the roots, while 78.03%~81.39%of cadmium was found in the leaves.
