Effects of application rate of agri soil conditioner on aroma quality of flue-cured tobacco leaves
Field experiments were carried out to study the effects of different Agri soil conditioner application rates (0, 3.75, 7.50, 11.25, 15.00 kg/ha) on aroma components, sensory quality and economic characteristics of flue-cured tobacco leaves. The results showed that increasing soil conditioner application rates, the contents of Maillard reaction products, carotenoid catabolites, aromatic amino acid catabolites and total aroma components, aroma quality and yield of leaf increased, output value, average price and proportion of high grade leaf raised at first and then reduced. At the conditioner application rate of 11.25 kg/ha, the contents of Maillard reaction products, carotenoid catabolites, aromatic amino acid catabolites, and total aroma components, aroma quality and yield of leaf were higher, and output value, average price and high grade leaf proportion were the highest.
