Abstract: The experiment aims to identify the application effects of cake fertilizers on growth, dry matter accumulation, plastid pigment of flue-cured tobacco. The results showed that all indexes of tobacco in different cake fertilizer treatments were better than those of CK, and cake fertilizer application significantly enhanced the growth potential of flue-cured tobacco, increased dry matter accumulation and plastid pigment content in tobacco leaves in pot experiments. The application of organic fertilizer could significantly improve the aroma premise material of flue-cured tobacco to increase the content of aroma substance. In addition, different cake fertilizer treatments showed different influences on the agronomic traits, dry matter accumulation, contents of nitrogen, phosphorus, and potassium, total chlorophyll and carotenoid content of flue-cured tobacco, and the best effects was found in combination 4 which could significantly increase the content of aroma material and be applied the cultivation and fertilization of flue-cured tobacco.
