摘　　要：为探索不同海拔下烟叶成熟度采收标准及采收时间,以张家界市主栽品种K326为研究对象,使用SPAD-502叶绿素仪测定了400和600 m海拔区域下上、中、下各部位不同成熟度鲜烟叶的SPAD值,分析不同成熟度下烟叶外观质量、感官质量及经济性状,找出不同海拔下各部位烟叶适宜采收的SPAD值。结果表明:400 m海拔下部烟叶适宜采收的SPAD值为26.57~29.99,中部鲜烟叶SPAD值为15.48~23.08,上部鲜烟叶SPAD值为17.19~20.81;600 m海拔下部烟叶适宜采收的SPAD值为21.60~24.06,中部鲜烟叶SPAD值为19.82~24.40,上部鲜烟叶SPAD值为13.49~16.65,烤后烟叶外观质量表现较优,感官质量属于较高档次。In order to explore the harvesting standards of tobacco leaf maturity at different altitudes,the main variety K326 in Zhangjiajie City was taken as the research object,and SPAD-502 chlorophyll analyzer was used to measure the SPAD values of fresh tobacco leaves with different maturity in the upper,middle and lower parts of the altitude area of 400 m and 600 m,and analyze the appearance quality,sensory quality and economic characteristics of tobacco leaves with different maturity.The aim is to find out the suitable SPAD value of different parts under different elevations.The results showed that the SPAD values of the lower tobacco were 26.57-29.99,the middle fresh tobacco 15.48-23.08,and the upper fresh tobacco 17.19-20.81 at 400 m altitude.At 600 m altitude,the SPAD values suitable for harvesting of the lower leaves were 21.60-24.06,the middle fresh leaves 19.82-24.40,and the upper fresh leaves 13.49-16.65.The appearance quality of the cured leaves was better,and the sensory quality was in a higher grade.
