摘　　要：为明确龙岩烤烟适宜移栽期,优化气候资源配置,在前期筛选的龙岩特征香气成分及其前体物基础上,结合龙岩近30年的1~2月的气候变化,通过移栽期试验,分析了烟叶的多酚、类胡萝卜素、β-胡萝卜素、叶黄素含量的差异,同时对比分析了烤烟的外观质量、化学成分、感官质量、经济性状和生育期的变化。结果表明:1月13日移栽(T1)显著促进了龙岩烤烟的特征香气成分前体物叶黄素的积累,较1月23日(CK)、2月2日移栽(T2)分别增加了67.78%和48.96%,产值显著增加,中部叶的感官评吸质量得分最高;而2月2日移栽(T2)的产值降低,中部叶可溶性糖含量降低,钾含量提高。由此可知,在龙岩烟区1月13日移栽较为适宜,气候资源配置较为合理。In order to clarity the suitable transplanting time of Longyan flue-cured tobacco and optimize the allocation of climate resources,the test of different transplanting time was carried out based on the characteristic aroma precursors and the climate changes from Jan to Feb in 30 years.The contents of polyphenols,carotenoids,β-carotene and lutein of tobacco leaves were analyzed,and the changes of appearance quality,chemical composition,sensory quality,economic characters and growth period were compared and analyzed.The results showed that transplanting on January 13(T1)significantly promoted the accumulation of lutein,which increased by 67.78%and 48.96%respectively,compared with transplanting on January 23(CK)and on February 2(T2).Furthermore,T1 was the best in the sensory evaluations of the middle leaves and the output value per hectare.Additionally,transplanting on 2nd February(T2)decreased the output value per hectare and the contents of soluble sugar,and increased the potassium content in tobacco.Therefore,transplanting on January 13 was the appropriate practice for optimizing the allocation of climate resources in Longyan.
