Abstract: "Effect of cake fertilizer and renewal matched on development and quality of flue-cured tobacco leaf were studied by laboratory analysis and serial trials.The results indicated that:Application of cake fertilizer and renewal which the proportion of nitrogen content was one-to-one could increase the tobacco leaf number,plant height,leaf length and width,and improve the tobacco plant disease,accelerate growth and development of flue-cured tobacco leaf,shorten the growth one to six days for flue-cured tobacco leaf.Significant differences at the 0.05 level among treatments were found for dry matter weight of the root,leaf and the whole plant,but the significant differences at the 0.05 level among treatments were not found for dry matter weight of the stems.The dry matter content of flue-cured tobacco leaf was higher which the treatment was that nitrogen content of cake fertilizer was higher,output and value were higher,too.The average price and hierarchical structure of flue-cured tobacco leaf was higher which the treatment was that nitrogen content of renewal was higher;Application of cake fertilizer and renewal which the proportion of nitrogen content was one-to-one increased the average price and hierarchical structure of flue-cured tobacco leaf,and improved the appearance quality of the flue-cured tobacco leaf,strengthened inherent quality of flue-cured tobacco leaf,improved aroma quality,aroma volume,and other sensory index.
