To clarify the suitable sowing and transplanting period for cigar tobacco in areas with different altitudes in Sanming, Fujian, meteorological elements at altitudes of 150-200 m and 700-800 m were compared and analyzed, and the effects of different transplanting periods on the growth, development, yield, and quality of cigar tobacco were studied respectively. The results showed that under the ecological conditions of the Sanming tobacco-growing area in Fujian, tobacco plants transplanted in mid-March in the 150-200 m altitude area and in mid-April in the 700-800 m altitude area showed strong growth potential, full growth and development, the best economic characteristics after air-curing, and the optimal sensory evaluation quality after agricultural fermentation. Transplanting too early was susceptible to low temperature and frost, resulting in slow or even stagnant growth of tobacco plants; transplanting too late shortened the field growth period, and high temperature often caused premature ripening in the later stage, affecting the economic benefits and smoking quality of cigar leaves. The research results were well validated in the production of cigar tobacco in the Sanming tobacco-growing area from 2023 to 2025.
