摘要： 为深入了解黔西南州烟叶总氮含量分布状况，测定黔西南州主产烟区烟叶总氮含量并研究其时空分布特征。结果表明：黔西南州烟叶总氮含量变幅在1.36%~2.42%，平均值为1.78%，属总氮含量较低烟区；贞丰县、兴义市、晴隆县烟叶总氮含量极显著高于兴仁县；总氮含量有逐年升高的趋势；总氮含量空间分布有从东北部向西南部递减的分布趋势。

Abstract: The total nitrogen content of flue-cured tobacco from main tobacco-growing areas in Qianxinan was determined by continuous flow method to study its space-time characteristic. The results showed that total nitrogen content of flue-cured tobacco belonged to lower-sugar tobacco-planting areas with a mean of 1.78%, amplitude of 1.36%-2.42%. The total nitrogen content of flue-cured tobacco in Zhenfeng County, Qinglong County, Xingyi City was extremely significant more than Xingren County. The total nitrogen content increased with the increase of the year. The total nitrogen content decreased gradually from the high total nitrogen content areas northeast of to southwest orientation.
