The general lack of soil boron nutrition in tea plantations under intensive tea production has seriously affected the yield and quality of tea. It is of great significance to study the effect of boron fertilizer application on tea efficiency and quality improvement to promote the high-quality development of tea industry. In this study，the effects of different fertilization methods and fertilization dosages of boron fertilizer on the yield，quality，economic benefits and soil fertility of tea were analyzed through the field experiment method. The results showed that the effect of tea yield increase under different boron application treatments was significant.Boron treatment increased the annual tea green yield by 7.79%-18.06%，dry tea yield increased by 9.31%-18.41%，germination density increased by 3.56%-18.32%. In summer and fall tea season，the amino acid content of tea leaves was elevated the highest by soil application of low amount of treatment(B1)，amounting to 37.31%；the caffeine and tea polyphenol contents were elevated the highest by foliar spraying once(B3)，amounting to 9.78% and 11.45% respectively；and the phenol-ammonia ratio of tea leaves was decreased the most by foliar spraying twice(B4)，amounting to 24.16%. Amino acid content of tea leaves in spring teaseason was elevated the highest with treatments of B4，amounting to 31.12%；tea polyphenol content was elevated the highest with one treatment of soil application of low amount + foliar spraying(B5)，amounting to 29.81%；and tea phenol-ammonia ratio was reduced the most in the treatment of B2，amounting to 15.18%. In the summer and fall tea seasons，soil application of B5 treatment increased the whole boron content of tea leaves by 47.01%；in the spring tea season，B2 increased the whole boron content of tea leaves by 45.62%，and B2 had the highest increase in soil available boron content，reaching 852.38%. B4 had the highest yield，net income，profitability and return on investment，with the yield increasing by 29000 Yuan per hectare compared to CK and the net income increasing by 14182 Yuan per hectare. The results of the study provide a useful reference for the scientific and rational application of boron fertilizer in tea gardens.
