施磷對(duì)南陽(yáng)煙區(qū)烤煙化學(xué)成分和香氣物質(zhì)含量的影響

Effects of Phosphorus Application on Chemical Components and Aroma Substance Contents of Flue-cured Tobacco in Nanyang

摘要: 以烤煙為供試作物,，研究了不同磷肥用量對(duì)烤煙化學(xué)成分和香氣物質(zhì)含量的影響。結(jié)果表明：磷能降低煙葉中淀粉含量,，縮小上下部位間煙堿差異,，改善煙葉的氮堿比，顯著提高苯甲醇,、氧化異佛爾酮,、巨豆三烯酮、新植二烯等主要香氣成分的含量,，改善煙葉的香吃味,。其中磷用量為90 kg/hm2 處理的煙葉化學(xué)成分協(xié)調(diào)性最好，主要香氣物質(zhì)成分含量及香氣總量最高,。

Abstract: This study was conducted to determine the effects of phosphorus application on chemical components and aroma substance contents of flue-cured tobacco leaves. Results showed that phosphorus fertilizer could decrease the starch content, reduce the differences between upper and lower leaves and improve the ratio of nitrogen to nicotine. Meanwhile, phosphorus application could significantly increase the main aroma components contents, such as benzyl alcohol, keto-isophorone, megastigmatrienone, and neophytadiene, resulting in the improvement of aroma and taste of tobacco leaves. Among all of the treatments, the tobacco leaves in treatment with phosphorus rate of 90 kg/hm2 exhibited the optimum coordination of chemical components and the highest contents of main aroma components.
