为了探索云烟97的最适施肥方案,以云烟97为试材,烟草专用复合肥为对照,研究了不同有机肥对烟草生育期、农艺性状、烟叶化学成分、感官评吸质量、经济性状等的影响。结果表明:施用有机肥可显著减缓烤烟的生长发育速度,成熟期比对照推迟近31 d,大田生育期比对照延长16 d;天泰有机肥处理的烟株团棵期长势较优,旺长期和成熟期以对照处理的烟株长势较好;施用有机肥可明显改善烟叶化学成分,感官评吸效果较好,其中以天泰有机肥处理的表现最佳;从综合经济性状及施肥成本来考虑,经济效益以天泰有机肥处理的最高,农福旺有机肥处理的次之,烟草专用复合肥处理的最差。可见,施用天泰有机肥可有效改善烟叶品质,提高烟叶经济性状,适合作为普洱地区云烟97品种有机种植的有机肥料使用。
In order to explore the optimum fertilization program of Yunyan 97, Yunyan 97 was used as experimental material and tobacco-specific compound fertilizer was used as control to study the effect of different organic fertilizers on tobacco growth period, agronomic traits, chemical composition of tobacco leaf, sensory evaluation smoking quality, economic traits influences. The results showed that the application of organic manure significantly slowed down the growth and development of flue-cured tobacco, the maturity was delayed by 31 days compared with the control and the growth period was 16 days longer than that of the control. Compared with the control, the tobacco plants grown at the mature stage grew well. The chemical composition of the tobacco leaves was improved obviously with organic manure applied, and the sensory evaluation was better. Among them, the treatment with Tiantai organic fertilizer was the best. From the comprehensive economic traits and fertilization cost Considered, the highest economic benefits of organic fertilizers Tiantai, followed by the treatment of organic fertilizers Wangfu, the worst for tobacco-specific compound treatment. Visible, the use of organic fertilizers Tiantai can effectively improve the quality of tobacco, tobacco leaf economic traits, suitable as a Pu’er Yunnan Yun 97 organic varieties of organic fertilizer use.
