分次追钾对襄阳烤烟钾含量及品质的影响

通过大田试验,研究了不同的追施钾肥方式和比例对襄阳烤烟物理特性、常规化学成分、中性致香物质和感官质量评价的影响,结果表明：分次追钾可以改善烤烟的物理特性,协调烟叶化学成分,显著提高了烤后烟叶的钾含量和有机钾指数,提高一些重要的香气物质含量,感官质量评价得分较高。以追钾2次的效果最好。...

The effects of applying potassium fertilizer at different stages and in different proportions on the physical properties, main chemical compositions, neutral aroma components, and sensory quality of flue-cured tobacco leaves were studied through field experiments conducted in Xiangyang city, Hubei province. The results showed that applying potassium fertilizer at several stages could improve the physical properties of flue-cured tobacco, harmonize the chemical compositions in tobacco leaves, significantly increase the potassium content and organic potassium index of baked tobacco leaves, enhance the content of some important neutral aroma components, and get higher score of sensory quality evaluation. Among various treatments, applying potassium fertilizer at two stages had the best effects.
