[目的]找出控制烟叶重金属含量的有效方法。[方法]在烤烟种植过程中进行大田试验,施用不同量的菜籽饼肥,探讨其对降低烟叶重金属含量的影响。[结果]施用不同量的菜籽饼肥作为基肥,对于降低烤烟重金属含量具有积极效应,其中施用量占总施肥量30%的处理,与对照相比具有显著性效果。[结论]该研究对于烟叶安全性的提升有积极效应,对于通过改善施肥方式、施肥种类等来提升烟叶安全性,以及对肥料的选择和前期处理提供了一定的科学指导,在实际生产中具有十分重要的意义。
[Objective] The research aimed to find out the effective method to control heavy metal content in tobacco leaves. [Method] The field experiments were conducted during the cultivation of flue - cured tobacco and different amounts of rapeseed cake fertilizer were applied to investigate the effects on reducing heavy metal content in tobacco leaves. [Result] Applying different amount of rapeseed cake fertilizer as basal fertilizer had a positive effect on reducing heavy metal content in flue-cured tobacco. The application of rapeseed cake fertilizer accounted for 30% of the total amount of fertilizer, which had significant effect compared with the control. [Conclusion] The study had a positive effect on the safety of tobacco leaves. It provided some scientific guidance for improving the safety of tobacco leaves by improving fertilizing methods and fertilization types, as well as providing some scientific guidance on fertilizer selection and pre-treatment. In practice, Very important meaning.
