为黔南州烟区土壤改良，合理调节土壤酸度提供参考，采用盆栽试验，研究了施用石灰调节土壤酸度对烤烟生长和烟叶品质影响研究。结果表明：当土壤pH值调节为5.4~6.9时，烟株的地上部农艺性状和根系生长发育较好，对N、P、K及Ca、Mg等微量元素的吸收利用效率较高；其中pH值在5.4~6.4间时，初烤烟叶的各种化学成分含量较适宜，且烟叶总糖烟碱比、总氮烟碱比和钾氯比等指标符合上等烟标准。可见施用石灰调节土壤pH值为5.4~6.4时，能有效促进烤烟生长，提高烟叶品质。

To provide a basis for reasonablely adjusting soil acidity in tobacco planting areas of southern Guizhou, a pot experiment was used for studying the effects of applying lime to adjusting soil acidity on growth of tobacco plants and quality of tobacco leaves. The results showed that when the soil pH was adjusted to 5.4~6.9, the tobacco plants had better agronomic characters and root growth, and also had high utilization efifciency in absorption of N, P, K, Ca, Mg and trace elements; when the soil pH was 5.4~6.4, the content of each component in cured tobacco leaves was appropriate, and the ratios of total sugar to nicotine, the ratio of total nitrogen to nicotine, and the ratio of potassium to chloride all met the standards of superior lfue-cured tobacco. According to the results, adjusting the soil pH to 5.4~6.4 by applying lime could promote the growth of tobacco plants and improve the quality of tobacco leaves effectively.
