| 摘 要： | 测定6个不同品种椰子凋落叶中的营养成分。结果表明,6个品种椰子凋落叶的叶柄中C、N、P、K、Na、Ca、Mg、Mn、Zn营养元素之间差异显著,其中Fe和Cu含量差异不显著;小叶中,C、N、P、K、Na、Ca、Mg、Fe、Mn、Zn营养元素之间差异显著,其中Cu含量差异不显著。同时,小叶中的C、N、Fe、Mn、Zn含量高于叶柄,而叶柄中的P、K、Na、Ca、Mg含量高于小叶。 |

| Abstract: | Nutritional components in leaf litters of different coconut cultivars were detected,and the differences of nutritional components were analyzed.Results revealed that the content of C,N,P,K,Na,Ca,Mg,Mn,Zn existed significant difference among coconut litter petioles of 6 different cultivars,while Fe and Cu content had no significance.The content of C,N,P,K,Na,Ca,Mg,Fe,Mn,Zn had obvious significance,however,Cu content had no significant difference in coconut leaflets.The content of C,N,Fe,Mn,Zn were higher in the leaflets,while P,K,Na,Ca,Mg contents were lower compared with that in the petioles.The results provided data bases to resource utilization of waste fronds in coconut gardens. |
| Keywords: | coconut leaf litter nutritional component petiole leaflet |
