不同烤烟品种留叶数对烤烟产量、化学成分、评吸质量的影响

为促进烤烟K326产量和质量协调和最优化，于2015—2016年采用大田试验，研究了不同留叶数对烤烟产量、化学成分、评吸质量的影响。以烤烟品种K326、红大、云87为材料，处理留叶数分别为16～22片／株。结果表明1不同留叶数对不同烤烟品种的影响不同，从经济性状出发，K326、红大、云87最适宜留叶数分别为22、20、18片／株；从化学成分出发，K326、红大、云87最适宜留叶数分别为20、16或18、20片／株。从评吸质量出发，K326、红大、云87最适宜留叶数分别为21、17、20片／株。综上所述，难做到烟叶质量、产量、效益的统一。从化学成分分析来看，各处理的氯、总氮和钾含量均在优质烟叶范...

Summary:为促进烤烟K326产量和质量协调和最优化，于2015—2016年采用大田试验，研究了不同留叶数对烤烟产量、化学成分、评吸质量的影响。以烤烟品种K326、红大、云87为材料，处理留叶数分别为16～22片／株。结果表明1不同留叶数对不同烤烟品种的影响不同，从经济性状出发，K326、红大、云87最适宜留叶数分别为22、20、18片／株；从化学成分出发，K326、红大、云87最适宜留叶数分别为20、16或18、20片／株。从评吸质量出发，K326、红大、云87最适宜留叶数分别为21、17、20片／株。综上所述，难做到烟叶质量、产量、效益的统一。从化学成分分析来看，各处理的氯、总氮和钾含量均在优质烟叶范围内。但总糖和还原糖均高于优质烟叶的两糖含量，这与云南特殊的气候环境有关，符合云南烟叶高糖含量的特点。
Bibliography:To promote the coordination and optimization of yield and quality of tobacco K326, field experiment was conducted to study the effects of different leaves number on yield, chemical components and smoking quality in 2015 to 2016. Tobacco K326, Hongda and Yun 87 were taken as the material, and the processing leaves number was 16 -22 piece per plant. The results showed that different leaves number had different effects on different tobacco varieties. The most suitable leaves number of K326, Hongda and Yun 87 were 22, 20, 18 piece per plant for economic traits, and 20, 16 or 18, 20 piece per plant for chemical composition, and 21, 17,20 piece per plant for smoking quali- ty. In summary, it is difficult to unify tobacco quality, yield and benefit. From the chemical composition analysis, the chlorine, total nitro- gen and potassium content of all treatments were in the range of high quality tobacco. But the total sugar and reducing sugar were higher than the two sugar content of high quality tobacco leaves, which i
