Influence of nitrogen application and jacking interaction on the construction of CB-1 plant and the quality of tobacco production
In order to provide scientific refences for rational fertilization and timely topping for flue-cured tobacco production,field production experiments were carried out through a two-factor randomized block design with nitrogen application amount(N)and topping time(D),in order to explore the effect of nitrogen application on the type construction of flue-cured tobacco CB-1 and tobacco yield and quality.The results indicated that different nitrogen application rates and topping interactions had a certain impact on the agronomic traits of tobacco leaves.Under the same nitrogen fertilizer application rate,different topping times had no significant effect on the agronomic traits of tobacco leaves.The agronomic traits,economic traits,and appearance quality of the treatment with a fertilization rate of 112.5 kg/hm2 and the interaction treatment of flowering and topping(treatment B)were all better,suitable for growth produce high-quality tobacco leaves and achieve relatively good economic benefits.
