Abstract

Abstract: A field experiment was designed to study effect of different fertilization mode on development of tobacco, yield and its quality. The results showed that compared with other fertilization treatments, potassium nitrate as topdressing and other fertilizers as basal fertilizer had the best comprehensive performance. Compared with the application of all fertilizers as basal fertilizer, potassium nitrate as topdressing can promote the development of tobacco plants in the growing and flat-topped periods, and the tobacco yield and output value are increased by 12.80% and 9.70%,respectively. The color, oil content and total score of middle and upper tobacco leaves increased by 2.50%~3.90%, 4.83%~9.43% and 1.68%~2.86%, respectively. The potassium content of middle and upper tobacco leaves increased by 14.29% and 16.89%, and the internal chemical composition of tobacco leaves was more harmonious.

Key words: fertilization mode, flue-cured tobacco, agronomical traits, appearance quality, chemical components
