Abstract:

This experiment aimed to provide reference for balanced fertilization, and investigate the annual accumulation of dry matter and nutrient in ‘Jinhuang’ mango in Hainan. Results showed: (1)The annual accumulation of dry matter in the ‘Jinhuang’ mango tree was in the order of: harvested fruits>pruning leaves>flower and peduncle>pruning branch>dropped fruits, and the flower and peduncle was responsible for 17.17%,the dropped fruits for 1.26%, the pruning leaves for 22.23%, the pruning branch for 8.64%, the harvested fruits for 50.70%. (2)The annual accumulation of eleven nutrients in the ‘Jinhuang’ mango tree was in the order of N>K>Ca>P>Mg>S>Mn>Fe>Zn>B>Cu. (3)And hence for a crop of 1000kg ‘Jinhuang’ fruit the consumption of nutrients were dry matter 464.68 kg, N 5.46 kg, P 0.57 kg, K 4.62 kg, Ca 2.69 kg, Mg 0.40 kg, S 0.33 kg, Fe 51.62 g, Mn 158.84 g, Cu 2.90 g, Zn 9.43 g, B 7.26 g.
