摘要: 烟草特有亚硝胺(TSNA)是致癌性极强的N-亚硝胺类化合物,形成TSNA的前体物有烟叶硝酸盐、亚硝酸盐及生物碱。土壤是烟叶生长的基础,通过调控土壤营养状况来限制烟叶硝酸盐、亚硝酸盐含量的积累,进而降低烟草TSNA的含量,对生产优质低害的烟叶原料具有重要的意义。综述了土壤有机质含量、pH值、主要营养元素等土壤肥力因素对烤烟叶片硝酸盐积累影响的研究概况。

Abstract: Tobacco-specific nitrosamines(TSNA) are the nitrogen compounds that could cause cancers strongly. The nitrate,nitrite and alkaloids are precursor to form TSNA in tobacco leaves. Soil is the basis of growth of tobacco plants. Therefore,it is of great importance to decrease the TSNA content and produce high quality and low harmful tobacco leaves by controlling soil nutrition conditions to reduce the accumulation of nitrate and nitrite in tobacco leaves. Effects of some soil fertility indexes including content of organic matter, pH value and main nutrient elements on nitrate accumulation in flue-cured tobacco leaf were summarized.
