摘要：

研究海南‘金煌’芒果干物质及养分年积累量，为平衡施肥提供参考。通过采集‘金煌’芒不同器官干物质并进行养分分析，结果表明：（1）‘金煌’树体不同器官干物质年积累量顺序为：采收果>修剪叶>花及梗>修剪枝>落果；其中花及梗占17.17%、落果1.26%、修剪叶22.23%、修剪枝8.64%、采收果50.70%。（2）‘金煌’树体11种营养元素年积累量大小顺序为：N>K>Ca>P>Mg>S>Mn>Fe>Zn>B>Cu。（3）以生产1000 kg‘金煌’芒计，树体养分需求为：干物质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。

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.
