Abstract: To improve the quality of tobacco seedling, promote tobacco plants to grow early and quickly, the modified floating nursery, sand-culture nursery, and conventional floating nursery were compared, and the effects of seedling mode on tobacco growth, yield and quality were studied. The results showed that: compared with conventional floating and sand-culture seedling nursery, modified floating nursery promoted seedling growth and development at all stages, every growth stage was in advance, seedling quality were excellent, seedling restitution stage after transplanting was shortened. Modified floating seedling plants had bigger stem girth after topping, but the height and internodes space were smaller than that of the control treatment; the nicotine content of middle and upper tobacco leaves were significantly improved, and the production value was higher than that of the control. Modified tobacco floating nursery improved the seedling quality obviously, promoted early growth and rapid development of tobacco plants in Fujian tobacco area in low temperature condition, and increased production value of tobacco leaves.
