Effects of Liquid Fertilizer on Growth and Development of Flue-Cured Tobacco

Field experiments were conducted to investigate the application effect of the liquid fertilizer with a brand Treasure of Tobacco on flue-cured tobacco production. The results showed that applying a certain amount of liquid fertilizer with appropriate reducing common tobacco specific fertilizer would not lead to adverse effect on the flue-cured tobacco growth, but tobacco plants would appear premature aging by greatly reducing common tobacco specific fertilizer. Compared with conventional fertilization, rational application of liquid fertilizer with reducing 10% of base fertilizer and 30% of topdressing, supplemented with liquid fertilizer, had no obvious influence on the yield, economical characters and chlorophyll content of tobacco leaf, but could improve the stress resistance of tobacco plant, the quality and usability level of tobacco leaf.
