農工業副產品做為盆栽文心蘭栽培介質之評估

Assessment of Agro-industrial By-products as Alternative Medium for PottedOncostele Cultivation

本研究探討與評估以農工業副產品做為替代性介質，對文心蘭生長與開花之影響。‘紫精靈’文心蘭以石塊、岩棉、天然纖維、多孔性陶瓷、椰塊、聚乳酸及草繩等七種替代性介質種植，結果顯示，以岩棉及多孔性陶瓷為栽培介質之文心蘭植株於假球莖的厚度、周徑及葉面積皆有較佳生育。於開花品質上，以岩棉栽培效果最佳，可顯著增加花梗及花序長度、側枝數以及花數，多孔性陶瓷栽培次之。而就生產成本與介質特性評估，多孔性陶瓷為廢棄磁磚再利用，質地輕巧，無害環境及可在地生產，能有效降低生產成本，為一具潛力之文心蘭替代性介質。 The effects of agro-industrial by-products as alternative medium on growth and flowering quality of pottedOncosteleWildcat 'Purple Fairy' were investigated. Plants of 'Purple Fairy' were cultivated with sevenagro-industrial by-products, which were stone, rockwool, natural fiber reinforced composites, porous ceramics, coir, poly lactic acid, and rope. The results showed that rockwool and porous ceramic were better than other growing medium for growth, especially on the pseudobulbs thickness, diameter and leaf area of pottedOns. Wildcat 'Purple Fairy'. Rockwool was the best medium for flower quality, which significantly increased length of flower-stalk and inflorescence, number of floret branches and floret number, followed by porous ceramics as medium. Considering the production cost, porous ceramic was a salvaged material during tile manufacturing. The characteristics of lightweight, environment friendly, local production, and lower cost make it a potential alternative medium for Oncostele cultivation.
