[Objective] The purpose of this paper is to improve the yield and quality of Chinese bayberry and promote the development of green-efficient bayberry industry. [Method] Taking Biqi bayberry as test materials, the application of humic acid soluble fertilizer(HASF)was studied for higher yield and better quality fruit, while two field experiments were conducted in Fumin County and Panlong District, Yunnan Province. [Result] The results showed that the yield and fruit quality were improved by spraying HASF with 800-1000 times concentration at pre-flowering, young fruit and fruit enlarged stage, based on conventional fertilization. The average single fruit weight, yield and net income of bayberry of spraying HASF were significantly higher than those of spraying water(CK), with up to 27. 86 %-31. 54 %, 13. 0 %-13. 4 % and 13. 8 %-14. 2 %, respectively, and the contents of soluble solids and vitamin C(Vc) increased by 18. 4 %-19. 54 %and 18. 56 %-24. 9 %, respectively. However, compared with conventional fertilization, spraying water had no significant effect on fruit yield and quality. [Conclusion] The yield, quality and economic benefit of bayberry could be improved significantly by applying HASF. [ABSTRACT FROM AUTHOR]
