摘　　要：采用描述统计和典型相关分析方法研究了保山烤烟化学成分与土壤养分状况之间的关系,结果表明:①保山土壤养分含量总体处于富足状态,但土壤养分不均匀,微量元素硼和氯含量较低,烟叶的总糖和还原糖含量较高,烟碱和总氮含量适中,钾、氯含量偏低;②在一定范围内土壤中碱解氮和有效硼含量与烟碱、总氮含量存在显著或极显著正相关,有效磷和有效镁含量与烟叶还原糖、钾氯比、糖碱比和氮碱比呈显著或极显著正相关;③控施氮肥,增施磷肥,提高烟株对土壤中钾的利用率,适当增施微肥,有利于提高保山烟叶的质量。The correlations between soil nutrients in Baoshan and the contents of chemical components in flue-cured tobacco were analyzed with descriptive statistics analysis and canonical correlation analysis.The results indicated that：1）Soils in tobacco-growing in Baoshan were generally rich in nutrients but the nutrients were not evenly distributed.The contents of total sugar and reducing sugar were higher,the contents of nicotine and total N were suitable,the contents of K and Cl were lower in flue-cured tobacco;2）Within a certain range,there was significant or extremely significant positive correlation between the contents of nicotine,total N in flue-cured tobacco and the contents of alkali-hydrolyzable N,available B in soil,a significant or extremely significant positive correlation between the contents of total sugar,reducing sugar,ratio of potassium to chlorine,ratio of total sugar to nicotine,ratio of total N to nicotine in flue-cured tobacco and the contents of available P,available Mg in soil;3）In order to improve the quality of flue-cured tobacco in Baoshan,it was necessary to control N fertilizer,apply more P and trace elements and promote the utilization of K fertilizer in soil.
