To investigate the effects of different fertilization methods on the quality of Liubao tea and the soil quality of tea gardens, taking the soil before fertilization as the control (CK), the tea yield, total nitrogen and other tea accumulation amounts, tea water extract, catechins and other tea quality indicators, soil physical and chemical properties such as pH and organic matter of Liubao tea under three fertilization methods, namely conventional fertilization (T0), artificial burial and formula fertilization (T1), and underground seepage irrigation formula fertilization (T2) were analyzed. The results showed that (1) the tea yield after T1 and T2 treatments was higher than that after T0, with the tea yield of T2 being higher. (2) The total phosphorus content of tea after T2 treatment was relatively high, and the total potassium content of tea after T1 treatment was relatively high. There was no significant difference in the total nitrogen content of tea under different fertilization methods. (3) Compared with T0, both T1 and T2 increased the contents of tea water extract, tea polyphenols, catechins, caffeine and free amino acids to a certain extent. Compared with CK, all three fertilization methods had enhanced the basic soil fertility (pH, total nitrogen, available phosphorus, available potassium, magnesium, zinc, and boron). In conclusion, the application of underground seepage irrigation formula fertilization can increase the yield and quality of Liubao tea leaves and has a certain improvement effect on the soil environment, which is conducive to the sustainable development of the tea industry.
Key words: Liubao tea; fertilization method; underground seepage irrigation; yield; quality
