The effects of organic and inorganic compound fertilizers for flue-cured tobacco on the growth
[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 1 800 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 1 800 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.
