Abstract: In order to explore the optimal application ratio of nitrogen, phosphorus and potassium fertilizer for Callicarpa kwangtungensis growth and function, a completely randomized block test with seven treatments was conducted, the treatments were Y0 (without fertilizer, CK), Y1 (15:5:6), Y2 (15:5:9), Y3 (15:3:12), Y4 (15:3:9), Y5 (15:3:6) and Y6 (15:3:3). The effect of different NPK fertilizer ratios on yield components (plant height, root diameter, new shoot number, leaf number), yield, forsythiaside B, poliumoside and total flavonoid content was studied. The results showed that Y1, Y3 and Y6 could improve the plant height, root diameter, leaf number and new shoot number, which led to the increase of yield. The results also indicated that the content of forsythiaside B, poliumoside and the yield reached the highest in Y1 treatment (15:5:6), which had the optimal NPK ratio that could ensure high yield and quality of Callicarpa kwangtungensis.
