The method comprises the following steps: flue-cured tobacco planting process, transplanting seedling age, tobacco leaf harvesting age, flue-cured tobacco field water management, and flue-cured tobacco field fertilization management. According to the method, timely early planting is adopted, water and fertilizer management is enhanced, and tobacco leaves grow early and quickly, so that it is guaranteed that the age of the tobacco leaves is sufficient, photosynthetic products are sufficient and perfect, and the maturity of the field tobacco leaves is improved; according to flue-cured tobacco field water management, the proper specific watering quantity is determined according to factors such as the soil structure, the air drought degree, the tobacco plant water shortage condition, and the tobacco plant size, the water requirement of tobacco plants can be met, and water is saved; in the flue-cured tobacco field growth and development process, moisture is supplied to tobacco plants in a balanced mode. In the field fertilization process, a technical regulation and control means of relatively concentrated space and relatively dispersed time is adopted, so that the tobacco leaves are sufficient and balanced in nutrition, and the maturity of the field tobacco leaves is improved.
