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1000kg‘金煌’芒计,树体养分需求为:干物质464.68kg、N5.46kg、P0.57kg、K4.62kg、Ca2.69kg、Mg0.40kg、S0.33kg、Fe51.62g、Mn158.84g、Cu2.90g、Zn9.43g、B7.26g。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 fruitspruning leaves flower and pedunclepruning branchdropped 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 NKCaPMgSMnFeZnBCu.（3）And hence for a crop of 1000 kg ＇ 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.
