摘要
为探究湖南蓝山烟区土壤理化性质对烟叶特性的影响,研究根据蓝山早禾基地单元烤烟种植分布确定了24个采样点,分析植烟区域土壤理化性质和烟叶特性,并进行相关性和回归分析。结果表明:对比烟叶生长土壤养分适宜范围和化学成分适宜范围,蓝山县烟田土全N含量、全P含量极高,而全K含量极低,土壤速效钾含量偏高,土壤有效磷含量、碱解氮含量、pH值适中,烤烟化学品质整体适宜,但烟叶总氮含量偏低,同时有20.83%的烟叶钾含量偏低。相关性分析表明,土壤速效钾、土壤碱解氮和土壤pH值显著影响烤烟品质。该烟区可优化氮肥和钾肥的施用方式,提高烟叶整体品质和当地烟农收入。
This study aims to explore the influences of soil physicochemical properties on tobacco leaf characteristics.Twenty-four sampling points were arranged according to the distribution of flue-cured tobacco planting units in Zaohe base in Lanshan,and the soil physicochemical properties and the characteristics of tobacco leaves were analyzed.Furthermore,correlation and regression analyses were conducted.The results indicated that the total nitrogen and total phosphorus in the tobacco fields of Lanshan County were significantly higher than the appropriate levels for tobacco growth,while the total potassium was very low.The content of available potassium in the soil was relatively high,and the levels of available phosphorus,alkali-hydrolyzable nitrogen,and pH value in the soil were moderate.Overall,the chemical quality of the flue-cured tobacco was appropriate,while the total nitrogen in the tobacco leaf was relatively low.In addition,20.83%of tobacco leaves had low potassium content.The correlation analysis showed that the factors that significantly affect the quality of the cured tobacco were available potassium,alkali-hydrolyzable nitrogen,and pH value of the soil.In this tobacco-producing area,the application methods of nitrogen fertilizer and potassium fertilizer can be optimized to improve the overall quality of tobacco leaf and increase the income of local tobacco farmers.
