| 中文摘要: |
| 通过对海南省乐东县贵妃芒干物质及养分年积累量研究，结果表明：⑴贵妃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13.67%、落果1.78%、修剪叶24.06%、修剪枝10.28%、采收果50.21%。⑵贵妃树体十一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。⑶以生产1000kg贵妃芒计，树体养分需求为：干物质496.46kg、N 5.81kg、P 0.69kg、K 4.83kg、Ca 3.20kg、Mg 0.48kg、S 0.35kg、Fe 37.91g、Mn 155.43g、Cu 4.41g、Zn 9.49g、B 9.40g。 |

| After researching on the annual accumulation of dry matter and nutrient in Guifei mango in Hainan.The results shown as follows:⑴The annual accumulation of dry matter in the Guifei 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 13.67%,the dropped fruits for 1.78%,the pruning leaves for 24.06%,the pruning branch for 10.28%,the harvested fruits for 50.21%.⑵The annual accumulation of eleven nutrients in the Guifei mango tree was in the order of N>K>Ca>P>Mg>S>Mn>Fe>Zn>B>Cu.⑶And hence for a crop of 1000kg Guifei fruit the consumption of nutrients were dry matter 496.46kg,N 5.81kg,P 0.69kg,K 4.83kg,Ca 3.20kg,Mg 0.48kg,S 0.35kg,Fe 37.91g,Mn 155.43g,Cu 4.41g,Zn 9.49g,B 9.40g. |
