Abstract

The invention belongs to the technical field of tobacco planting and particularly discloses a planting method for improving the quality of tobacco leaves of the flue-cured tobacco variety NC55. The planting method comprises the steps of: growing seedlings, transplanting the seedlings, applying fertilizers, irrigating, preventing disease and insect damage, topping and removing wooden forks and picking when ripening; and transplanting the seedlings of the flue-cured tobacco variety NC55 to a special transplanting medium for the flue-cured tobacco variety NC55 to carry out planting. The special transplanting medium for the flue-cured tobacco variety NC55 comprises the following components in parts by weight: 90-110 parts of sandy mud, 80-100 parts of bovine liver soil, 30-40 parts of purple soil, 20-30 parts of dark loessial soil, 10-20 parts of loessal soil, 10-20 parts of sierozem, 30-50 parts of river sand and 10-15 parts of humic acid. The planting method disclosed by the invention has the advantages that the sensory quality and the quality of the tobacco leaves of the NC55 can be obviously improved; in addition, the sugar-nicotine ratio in the tobacco leaves of the NC55 also can be obviously reduced, and the benefit for prominence of the style characteristic of the tobacco leaves of NC55 is achieved.
