Abstract: The problems of insufficient nutrient supply of bayberry[Myrica rubra (Lour.) S. et Zucc.] tree body, tree potential and fruit quality were declinded. In order to improve the vegetative growth and fruit quality, amino acid water-soluble fertilizer was sprayed at the fruit expansion stage of Biqizhong and Dongkui in greenhouse. The shoot length and shoot diameter of Biqizhong were 5.01% and 5.95% higher than the control respectively, the relative conductivity of Biqizhong was 44.88% lower than that of the control, and the contents of soluble solids, total sugar and vitamin C of Biqizhong fruits were 12.09%, 7.83%, and 10.67% higher than the control, respectively. The chlorophyll content of Dongkui was 13.87% higher than the control, and the contents of soluble solids, total sugar and vitamin C of Dongkui fruit were 6.18%, 7.28% and 7.52% higher than the control, respectively. In conclusion, the bayberry vegetative growth, and fruit quality were significantly increased by amino acid water-soluble fertilizer, and it is worthy of moderate application on bayberry in greenhouse.

Key words: Myrica rubra (Lour.) S. et Zucc. in greenhouse, amino acid water soluble fertilizer, vegetative growth, fruit quality
