以烤烟品种革新３号及棕壤、褐土、潮土和沙姜黑土为试验材料，进行烟草吸收稀土的动态研究，结果表明，自还苗以后，叶的稀土含量及吸收量显著高于茎和根，在现蕾期达到最高值。生育后期叶中的稀土向生殖器官转移。稀土在烟草生长的团棵期活力较强，因此稀土宜施用在烟草的生长前期，土壤的稀土含量状况也影响着烟草对稀土的吸收。成熟期烟草各器官稀土的含量顺序为叶＞茎＞种子＞根。
The results showed that the rare earth contents and uptake of leaves were significantly higher than those of the stems and the roots after the seedlings were self-cured, and the brown tobacco, brown soil, fluvo-aquic soil and shajiang black soil were used as experimental materials. Root, reaching the highest value in the budding period. Rare leaves in the late reproductive organs to reproductive organs transfer. Rare earth in the growing group of tobacco vitality, so the rare earth should be applied to the growth of tobacco in the early stage of the soil, the content of rare earth also affects the absorption of rare earths. The contents of rare earth elements in leaves of mature tobacco were leaf> stem> seed> root.
