Abstract: Abstract: In order to study the influence of topping method in different transplanting periods on the cutting characteristics of "Honghuadajinyuan" upper leaves, field randomized block experiment was carried out. According to the results, the topping of central red flowers during blooming and topping during full-bloom stage adopted on March 25, the topping of central flowers during blooming adopted on April 1, and the topping of central flowers during blooming adopted on April 5 can reduce the nicotine content of upper leaves, increase the nicotine content of lower leaves as well as improve the overall quality of tobacco leaves. To sum up, early transplantation of tobacco leaves in conjunction with topping of central flowers during blooming and topping during full-bloom stage can effectively reduce the nicotine content of upper leaves.
