摘　　要：本文研究了不同SPAD值对烤烟中部叶单叶重、经济效益、化学成分、外观质量和感官评吸质量的影响。试验结果表明,SPAD值16~25,均价、上等烟比例、产值最高,内在化学成分协调,烤后烟叶外观质量和感官评吸质量最好。适时早采有利于提高中部叶单叶重。Effect of different Soil and Plant Analyzer Development (SPAD) value on weight of single leaf, economic benefit, chemical components, appearance quality and sensory quality of cutter leaves of flue-cured tobacco was studied in the paper. The results showed that when SPAD value was 16 - 25, the average price, ratio of high grade leaves, the output value were the highest;chemical components were coordinated;the appearance quality and sensory quality of flue-cured tobacco were the best. Timely and early harvesting was beneficial to increase weight of cutter single leaf.
