摘　　要：【目的】为探究烤烟专用有机-无机复混肥对烤烟K326生长的影响。【方法】在广西百色植烟区采用田间试验方法,以K326为试验材料,设置3个不同施肥量处理,以当地常规施肥处理为对照。在追肥时间和次数一致的情况下,研究常规施肥和烤烟专用有机-无机复混肥对K326产量和质量的影响。【结果】以施用1800 kg/m2烤烟专用有机-无机复混肥处理效果最佳,其株高、茎围和上部叶叶长和叶宽分别较CK组增加了4.22%、3.00%、4.85%和2.25%,促生效果显著;烟株抵御病害能力增强,常见病害发生率降低29.26%~52.53%,产量和产值分别较常规对照增加8.96%和13.41%,经济效益显著;同时烟叶化学成分协调性和物理特性均在适宜范围内,且香气质较好,杂气和刺激性明显减少,余味舒适,浓度适中。【结论】施用1800 kg/m2烤烟专用有机-无机复混肥,能有效改善K326烟株农艺性状,降低病害发生率,增加经济效益,同时烟叶化学成分协调性、物理特性和感官质量均有所提升,可在广西K326种植区推广使用。[Objective]This study was conducted to investigate the effects of organic and inorganic compound fertilizers for flue-cured tobacco on the growth of tobacco K326.[Method]Field experiments were conducted in the tobacco growing area in Baise of Guangxi,using K326 as the experimental material.Three different fertilization treatments were set up,with the local conventional fertilization treatment as the control.A study on the effects of conventional fertilization and organic and inorganic compound fertilizers for flue-cured tobacco on the yield and quality of tobacco K326 under the same topdressing time and frequency was conducted.[Result]The results showed that the application of 1800 kg/m2 organic and inorganic compound fertilizers for flue-cured tobacco had the best effect,and its plant height,stem circumference,and upper leaf length and width increased by 4.22%,3.00%,4.85%,and 2.25%,respectively,compared to that of the conventional control group,and so it had significant growth promoting;the ability of tobacco plants to resist diseases had been enhanced,and the incidence of common diseases had decreased by 29.26%to 52.53%.The yield and output value had increased by 8.96%and 13.41%,respectively,compared to that of the conventional control,and so it had significant economic benefits;at the same time,the coordination of chemical components and physical properties of tobacco leaves were within an appropriate range,and the aroma and temperament were good,with a significant reduction in impurities and irritation.The aftertaste was comfortable,and the concentration was moderate.[Conclusion]Overall,the application of 1800 kg/m2 organic and inorganic compound fertilizers for flue-cured tobacco could effectively improve the agronomic characteristics of K326 tobacco plants,reduce disease incidence,increase economic benefits,and improve the coordination of chemical components,physical properties,and sensory quality of tobacco leaves.It can be promoted and used in K326 planting areas in Guangxi.
