摘要

優雅椰子外型優美，適合盆栽利用。本試驗以二年生優雅椰子為材料，進行遮光及介質二試驗；並以一年生優雅椰子為材料，進行液肥試驗，探討優雅椰子盆栽適當的栽培條件，以建立優雅椰子生產體系供農友種植參考。試驗結果優雅椰子在60%遮光網下盆栽，植株之株高、莖徑及展幅表現較佳，葉片數及葉色則以在60－80%遮光網下盆栽，表現較佳。介質的施用上，在四種光環境下有相似的趨勢，即是以田土+蛇木屑（體積比1：1）對優雅椰子盆栽生育有較佳的性狀。在80、60及40%遮光網下盆栽，皆以每週施用Peters液肥稀釋1000－2000倍，可得到最佳植株生育性狀；但在露天環境亦下以每週施液肥稀釋1000－2000倍，植株生育較佳。

Ptychoraphis augusta is a newly imported plants, has beautiful plant form and suitable growth habits for potted interior use. These separated experiments were proceeded to establish an optimum cultivating system for local farmers. Shading net (0, 40, 60, and 80%) and substrate (peat: tree fern, peat: loam, tree fern: loam = 1:1 v/v; and loam) treatments were conducted on two-year old plants. Water-soluble fertilizers of four concentrations were applied on one-year old seedlings. Through these experiments, we hope to establish the production system of Ptychoraphis augusta and those will be recommended to local farmer.Results showed Ptychoraphis augusta under 60% shading net can obtain taller plant, wider stem and leaf spreads. Plants under 60 and 80% shading had darker green leaves. Tree fern: loam and loam grown plants had better horticultural characteristics. Under shaded environments, fertilizing once a week with Peters (30-10-10), diluted 1000-2000x, produced plants of better quality and growing faster. In outdoors, concentrations of 1000 and 2000x treated plants grew better.
