| 摘 要： | 采用5种晾房(竹笆涂泥晾房、美式全板晾房、黒膜夹草晾房、全黑膜晾房、黒膜推杆晾棚)和2种采收方式(半整株采收和摘叶采收)研究了白肋烟晾制过程中生物碱、总氮含量及氮碱比的变化。在烟叶晾制过程中,烟碱和总生物碱含量总体呈下降趋势,降烟碱、假木贼碱和新烟草碱变化相对较小。竹笆涂泥、美式全板、黒膜夹草3种方式烟碱含量的下降幅度相对较大,中部叶和上部叶下降幅度分别为17.6%~27.6%和16.5%~19.7%,晾制后烟叶生物碱含量和氮碱比较为适宜;而黑膜推竿晾制和全黑膜晾房的烟叶烟碱含量降低幅度较小,氮碱比偏小。摘叶采收烟叶烟碱含量较高,氮碱比较小,且在晾制过程中含量下降幅度较小,这与其失水干燥较快,调制过程较短有关。 |
| 关 键 词： | 白肋烟 晾房 生物碱 烟碱 总氮 氮碱比 |

| Abstract: | 5 air-curing barns(bamboo-mud barn,American wooden plate barn,black plastic with grass barn,all-black plastic barn,plastic covering structure) and 2 harvesting manner(half-stalk cutting,priming) were used to investigate the changes in alkaloid and total nitrogen contents and the ratio of nitrogen to nicotine during air-curing.The results showed that nicotine and total alkaloid contents decreased with the curing process;the contents of nornicotine,anabasine and anatabine showed no significant changes.Nicotine contents for bamboo-mud barn,American wooden plate barn and black plastic with grass barn decreased more than that for all-black plastic barn and plastic covering structure,and the decreased percentage for the former 3 barns was from 16.5 % to 19.7 % for upper stalk leaves,and 17.6 % to 27.6 % for middle stalk leaves,and the nitrogen to nicotine ratio in air-cured leaves was adequate.The nicotine contents for primed leaves were higher than that for half-stalk cutting tobacco,and the nitrogen to nicotine ratio was lower,which was related to the rapid drying and shorter curing process. |
