Effect of Different Formulations of Foliar Fertilizers on the Tea Quality of Yunkang 10
In order to study the effect of different formulations of foliar fertilizers on th tea quality of Yunkang 10,potassium dihydrogen phosphate was selected as the basic fertilizer,and urea,small peptide and trace elements were added respectively to spray the Yunkang 10 tea tree.The results showed that spraying small peptides+potassium dihydrogen phosphate+trace elements resulted in the highest 100-bud weight of tea trees,reaching 20.32 g;In terms of internal components,the highest content of water extract was achieved by spraying small peptides,potassium dihydrogen phosphate,and trace elements,reaching 44.11%.The content of free amino acids was highest in the treatment of spraying small peptides and potassium dihydrogen phosphate,and there was a significant difference compared to the control group(water group);There were significant differences in tea polyphenols and caffeine compared to the control group treated with urea+potassium dihydrogen phosphate,small peptides+potassium dihydrogen phosphate.The sensory evaluation results of tea samples showed that the treatment of spraying small peptides,potassium dihydrogen phosphate,and trace elements had better appearance(90 points),liquor color(88 points),aroma(92 points),taste(87 points),and infused leaf(90 points)than other treatments,with the highest comprehensive sensory score(89.40 points).
