在印度尼西亚ＰＴＰｕｌａｕＳａｍｂｕＧｒｏｕｐ所属的种植园内对５年生椰子－菠萝复合系统营养元素的吸收、转移、归还全过程进行了系统的测定和分析。结果表明该复合系统营养元素（氮、磷、钾）的年存留、归还、吸收量分别为５５９４７１、４１０７４５和９７０４７５ｋｇ·ｈｍ－２。营养元素的平均循环率为４２３２％，比纯椰林提高了２７５３％。椰林下间种菠萝，由于两者对营养元素吸收具有互补性，菠萝根茬还田增加了营养物质的归还量，提高了营养物质的利用率，系统的功能得到明显的增强。椰子－菠萝复合经营是一种生产力较高、资源利用率较好的热带作物优化栽培模式。
The whole process of nutrient absorption, transfer and return in 5-year-old coconut-pineapple composite system was systematically determined and analyzed in the plantation owned by PT.PulauSambuGroup in Indonesia. The results showed that the annual retained, returned and absorbed amounts of nutrients (nitrogen, phosphorus and potassium) of the composite system were 559471, 410745 and 970475 kg · hm-2, respectively. The average nutrient recycling rate was 4232%, which was 2753% higher than pure coconut. Under the coconut grove species of pineapple, due to the two of the absorption of nutrients are complementary, pineapple stubble returned to the field to increase the return of nutrients, improve the utilization of nutrients, the system functions have been significantly enhanced. Coconut - pineapple complex is a high productivity, better utilization of resources tropical crop optimization cultivation mode.
