Abstract: For the relationship between selected flue-cured tobacco leaves, mature and effective accumulated temperature, the pot experiment was conducted to study the relationship between the ‘HD’ and ‘K326’ variety of different transplanting time and different fertilization conditions in 4, 10 and 16 leaf tobacco, mature and effective accumulated temperature, analyzed the influence on tobacco growth and quality of tobacco. The results showed that, different transplanting time fourth leaf maturity required for effective accumulated temperature of 304.9~370.6℃, tenth leaf maturity required for effective accumulated temperature of 569~706℃, sixteenth leaf maturity required for effective accumulated temperature of 758.3~812℃. Comprehensive analysis showed that the same tobacco leaf maturity accumulation the effective accumulated temperature was relatively stable range, we can through the field test with different leaf position occurs, mature and effective accumulated temperature relationship for guiding the production feasibility.
