栽培介質、緩效性肥料和廄肥對臺灣山蘇花生長之影響

Effect of Growing Medium, Slow Release Fertilizer and Manure on Growth of Asplenium nidus

臺灣山蘇花於網室栽植，研究不同栽培介質、緩效性肥料和廄肥對生長之影響。栽培介質以泥炭土／真珠石（Cornell peat-litemix）混合介質，或泥炭土／真珠石／蛇木屑（1：1：1）較該介質拌入炭化稻穀和杉木屑或單獨使用蛇木屑為佳。在泥炭土／真珠石／蛇木屑（1：1：1體積比）拌入2 g/l Osmocote（14N-6.1P一11.6K）或5%體積比之牛糞、豬糞能增進植株生長，且以Osmocote優於廄肥；雞糞效果不良，而蚯蚓糞則尚看不出優劣。栽培介質理化性質分析顯示通氣性及保肥力最為重要。

Effect of growing medium, slow release fertilizer and manure on growth of Asplenium nidus grown at shade house were studies. The peat-lite mixes or peat/perlite/treefern mixes were better than the peat-lite mix containing 1/4 (by volume) sawdust and 1/4 ricehull for frond growth. Growth of frond was enhanced by medium (composed equal part of peatmose, perlite and treefern) enriched with 2g/l Osmocote (14N-6.1P-11.6K) or 1/20 volume of dairy or hog manure. However, the growth of frond was inhibited when medium enriched with chicken manure. There are not significantly difference between control and medium enriched with earthworm casting. It seems likely that air capacity and nutrient holding capacity are the main factors controlling the frond growth of Asplenium nidus.
