摘要:
为进一步通过科学施肥改善土壤理化性质，提升土壤肥力，从而提升烤后烟叶品质，通过对陕西省洛南县3个植烟镇的烟田土壤和烟叶样本的采集与分析，运用描述性统计、简单相关性及典型相关性分析方法对植烟土壤理化特性与烟叶化学组分之间的关联性进行了深入研究。结果显示，洛南县植烟土壤的pH、有机质、全氮、碱解氮及速效钾含量适中，而有效磷含量尤为丰富。其中，景村镇土壤pH、有效磷和速效钾含量表现最高，永丰镇则相对较低；而永丰镇有机质、全氮和碱解氮含量则占据优势，景村镇则相对较低。洛南县烟叶的总糖含量普遍偏高，而钾、氯含量及氮碱比较低，其他化学指标均处于适宜范围。永丰镇烟叶总糖含量最高，而景村镇烟叶钾、氯含量及氮碱比几个指标表现最低。相关性分析进一步揭示了土壤pH与烟叶总糖、总氮含量呈负相关，与氮碱比呈正相关；土壤中碱解氮含量与烟叶总糖、总氮含量呈正相关；而烟叶氯含量则与土壤有效磷含量呈负相关。综上，可以通过调控土壤主要因子（如pH、有效磷和碱解氮）来优化烟叶中的总糖、总氮、氯离子含量及氮碱比，从而提高洛南县烟叶的整体品质和化学协调性。
Abstract:
In order to further improve soil physical and chemical properties and enhance soil fertility through scientific fertilization, and thus improve the 3quality of tobacco leaves after baking, a detailed study was conducted on the correlation between soil and tobacco samples from three tobacco planting towns in Luonan County, Shaanxi Province, and the chemical components of tobacco leaves using descriptive statistics, simple correlation, and canonical correlation analysis methods. The results showed that， the average contents of pH, organic matter, total nitrogen, alkali hydrolyzable nitrogen and available potassium in Luonan County were appropriate, and the average content of available phosphorus was abundant. Among them, the pH value, available phosphorus and available potassium of tobacco planting soil were the highest in Jingcun Town, and the lowest in Yongfeng Town. Organic matter, total nitrogen and alkaline hydrolyzable nitrogen of tabacco planting soil were the highest in Yongfeng Town, and the lowest in Jingcun Town. The average content of total sugar in tobacco leaves in Luonan County was high, and the potassium content, chlorine content and nitrogen-alkali ratio were low, and the contents of other indicators were appropriate. Among them, Yongfeng Town had the highest total sugar content in tobacco leaves, and Jingcun Town had the lowest potassium content, chlorine content and nitrogen-alkali ratio. The results of simple correlation and typical correlation analysis showed that within a certain range, the total sugar and total nitrogen content of tobacco leaves in Luonan County were significantly negatively correlated with soil pH, and positively correlated with soil alkali-hydrolyzable nitrogen content, the chlorine content of tobacco leaves was significantly negatively correlated with the available phosphorus content in soil, and the nitrogen-alkali ratio was significantly positively correlated with soil pH. In summary, the content of total sugar, total nitrogen, chloride ion and nitrogen-alkali ratio in tobacco leaves can be improved by adjusting the content of major soil factors (pH, available phosphorus, alkali hydrolyzable nitrogen), so as to make the chemical composition of Luonan tobacco leaves more harmonious and improve the comprehensive quality of Luonan tobacco leaves.
