摘要
为了了解土壤理化性质对烟叶物理特性的影响,进一步提高烟叶质量,对四川烟区不同产区土壤理化性质与烟叶物理特性的关系进行分析,相关分析结果表明,耕层质地(x_2)与单叶质量(y_3)极显著负相关(-0.656);土壤有机质(x_4)与叶宽(y_2)极显著正相关(0.683),其他土壤属性对烟叶物理特性各指标均有不同程度影响;典型相关分析表明,土壤理化性质对烟叶物理特性的影响主要表现在土壤速效氮(x_5)对烟叶叶质重(y_5)的影响,以及土壤耕层厚度(x_1)、速效钾(x_7)对烟叶叶长(y_2)与含梗率(y_4)的影响。因此在烟叶生产过程中可以通过控制施肥等措施改善土壤属性进而提高烟叶的物理特性。
In order to understand the effect of soil physical and chemical properties on the physical characteristics of tobacco leaves and to further improve the quality of tobacco leaves, the soil properties and the physical characteristics of tobacco leaves in different areas of Sichuan tobacco-growing areas were evaluated and analyzed. The results showed that top soil texture（x_2） had a significant negative correlation with leaf weight（y_3） while soil organic matter（x_4） had a significant positive correlation with leaf width（y_2）, and the coefficient were -0.656 and 0.683, respectively. Other soil properties had different effects on the physical characteristics of tobacco leaves. Based on the canonical correlation analysis, the main effects of soil physical and chemical properties on the physical characteristics of tobacco leaves were the effect of soil available nitrogen content（x_5） on the leaf specific weight（y_5） and soil plowing thickness（x_1）, available potassium（x_7） on the leaf length（y_2） and stem ratio（y_4）. Therefore, the physical properties of tobacco leaves could be improved by controlling the fertilization and other measures in the tobacco production process.
