烤烟施磷量与经济性状·评吸质量的相关分析

Correlation Analysis of Phosphorus Application Amount and Economic Characters of Flue-Cured Tobacco,Smoking Quality

[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] The research aimed to clarify the relation between fertilizer amount and flue-cured tobacco quality.[Method] Using randomized block,the influence of different amount of phosphorus on the smoking quality and economic characters of flue-cured tobacco leaves was studied.[Result] The economic traits of the low amount of phosphate treatment were higher than that of high amount of fertilizer treatment.The content of reducing sugar and total sugar of tobacco upper leaves of lower X2F and B2F were significantly higher than that of CK,and total nitrogen and nicotine content were significantly lower than that of CK.The nicotine content in tobacco leaf C2F was significantly higher than that of CK,and the potassium content was significantly lower than that of CK.Fertilizer had a great influence on the leaf C2F.Compared with CK,P treatments could increase the aftertaste,weaken miscellaneous gas,provocative,and improve the smoking total scores by 0.14%-2.26%.Phosphate fertilizer consumption and smoking quality indicators of quality and quantity of flavor,mixed gas,stimulation,smoking total scores showed a weak correlation,and the correlation wasn’t significant.[Conclusion] The study provided a scientific basis for the application and popularization of flue-cured tobacco.
