为研究昭通市土壤有机质对烟叶品质的影响,选取昭通市9个植烟县的土壤和烟叶为研究对象,分析其土壤有机质含量差异对烟叶的外观质量、香气量和烟碱含量的影响。结果表明:昭通市大部分土壤有机质含量在1~3%的范围内,适合生产优质烤烟,且随着土壤有机质含量增加,烟叶烟碱含量、烟叶香气量评吸得分、烟叶外观质量总分逐渐增加。本研究成果为昭通烟区制订优质烟叶配套栽培技术提供了科学依据,对指导烤烟生产具有应用价值。
In order to study the effect of soil organic matter on tobacco leaf quality in Zhaotong City, the soil and tobacco leaf of nine tobacco-planting counties in Zhaotong City were selected to study the effects of soil organic matter content differences on appearance quality, aroma and nicotine content. The results showed that most of the soil organic matter content of Zhaotong City was in the range of 1-3%, which was suitable for producing high quality flue-cured tobacco. With the increase of soil organic matter content, nicotine content, increase. The results of this research provide a scientific basis for formulating high-quality tobacco cultivation techniques in Zhaotong tobacco-growing areas and have application value for guiding the production of tobacco.
