[目的]为了明确磷肥用量与烤烟质量的关系。[方法]采用随机区组,研究不同磷肥用量对烤烟经济性状、烟叶评吸质量的影响。[结果]低磷肥处理的经济性状在0.05水平显著高于高磷肥处理。施磷肥的处理下部烟叶X2F、上部烟叶B2F的总糖、还原糖含量明显高于对照,总氮、烟碱含量明显低于对照。中部烟叶C2F烟碱含量明显高于对照,钾含量明显低于对照。磷肥用量对C2F烟叶有较大的影响。与对照相比,施磷处理余味增加,杂气、刺激性减弱,评吸总分提高0.14%～2.26%。磷肥用量与评吸质量指标香气质、香气量、杂气、刺激性、评吸总分呈弱相关,相关性均不显著。[结论]该研究为烤烟施肥与示范推广提供科学依据。
[Objective] In order to clarify the relationship between the amount of phosphate fertilizer and the quality of flue-cured tobacco. [Method] The randomized block was used to study the effects of different phosphate fertilizer dosages on economic traits and smoking quality of flue - cured tobacco. [Result] The economic traits of low phosphate fertilizer treatments were significantly higher than those of high phosphate treatments at 0.05 level. Phosphate fertilizer treatment lower tobacco X2F, upper leaves B2F total sugar, reducing sugar content was significantly higher than the control, total nitrogen, nicotine content was significantly lower than the control. The content of C2F nicotine in the middle tobacco leaf was significantly higher than that of the control, and the potassium content was obviously lower than that of the control. The amount of phosphate fertilizer on C2F tobacco has a greater impact. Compared with the control, the aftertaste of phosphorus application increased, the miscellaneous gas and irritation weakened, and the total score of aspiration increased by 0.14% -2.26%. Phosphate fertilizer quality and smoking quality indicators aroma quality, aroma, miscellaneous gas, irritation, total score was weakly related to suction, the correlation was not significant. [Conclusion] The research provided the scientific basis for the fertilization and demonstration promotion of flue-cured tobacco.
