To explore the effects of underground infiltration irrigation of amino acid fertilizer on the soil nutrients and tea quality of Liubao tea garden, this experiment took the soil before fertilization as the control (CK), two fertilization models of formula fertilization (TS0) and formula fertilization + underground infiltration irrigation of amino acid fertilizer (TS1) were set in this experiment. The pH, total nitrogen content of the tea garden soil, tea yield, water extract and free amino acid content, etc. after treatment were measured with the non-fertilization treatment as the control (CK). The results showed that both TS0 and TS1 could increase the soil nutrients, and compared with CK, TS1 significantly increased the contents of total nitrogen, available phosphorus and available potassium in the soil. The tea yield after TS1 treatment was higher than that of TS0. The contents of tea extract, tea polyphenols, catechins, caffeine and amino acids after TS1 treatment increased by 42.61%, 86.69%, 26.20%, 51.25% and 73.91%, respectively, compared with TS0. In conclusion, the application of formula fertilization plus underground infiltration irrigation of amino acid fertilizer can significantly improve the soil nutrient content, tea yield and quality of Liubao tea garden.
