不同打顶时间和留叶数对云烟97产质量的影响

通过田间试验,研究了不同打顶时间和留叶数对云烟97生长发育和产质量的影响。结果表明,打顶时间和留叶数对云烟97农艺性状和经济性状有显著影响;50%中心花开放打顶留取16片叶处理经济性状最好;50%中心花开放打顶留取14片处理和16片叶处理,烟叶感官质量最佳。综合分析认为,在当地生态条件下,选择50%中心花开放打顶,留取14~16片有效叶,云烟97可以获得较好的产质量。

Effects of Different Topping Time and Remained Leaf Numbers on Yield and Quality of Flue-cured Tobacco Variety Yunyan 97

The effects of different topping time and remained leaf numbers on growth, yield, and quality of flue-cured tobacco Yunyan97 were studied through field experiments in Wannan, Anhui Province. The results showed that topping time and remained leaf numbers affected the agronomic and economic traits significantly. The best economic traits were obtained when topping at 50% center flowers open with 16 leaves remained, while the highest aroma quality, amount of aroma, aftertaste and total score were obtained when topping at 50% center flowers open with 14 and 16 leaves remained. Topping at 50% center flowers open with 14 and 16 leaves remained are thus recommended for tobacco production in this region.
