| 摘要 | [Objectives] To investigate the effects of different planting densities and nitrogen application rates on the yield and quality of the tobacco cultivar Chuxue 80. [Methods] A field experiment was conducted in Hubei Province, evaluating various combinations of planting density and nitrogen rate for Chuxue 80. [Results] At the maturity stage, the TN1 treatment (5 kg N per 667 m2 with a density of 1 900 plants per 667 m2) demonstrated the most favorable agronomic performance. The TN9 treatment (11 kg N per 667 m2 with a density of 1 110 plants per 667 m2) achieved the highest wrapper tobacco yield and output value. Meanwhile, the TN5 treatment (8 kg N per 667 m2 with a density of 1 515 plants per 667 m2) resulted in the best smoking quality. [Conclusions] The TN9 treatment, with a planting density of 1 110 plants per 667 m2 and a nitrogen application rate of 11 kg per 667 m2, is recommended as the optimal cultivation practice for Chuxue 80 in Hubei Province. |
