| 中文摘要 | 本研究探討以樹皮作為蝴蝶蘭(Phal. Sogo Yukidian) 生長介質之可行性, 以提供蝴蝶蘭生產之另一項選擇。本研究除分析該介質之理化特性外, 並探討不同養液澆灌頻率及濃度對樹皮所栽培之蝴蝶蘭的生長效益。研究結果顯示,進口紐西蘭樹皮介質之pH 值5.00-6.12 和水苔之間無顯著性差異(p<0.05) , EC 值較低, 樹皮介質之每公克乾物重之最大保水重及每盆之最大保水量明顯低於水苔;樹皮介質之保水特性亦明顯比水苔差, 不同粒徑之樹皮介質,澆灌7天後其保水率即趨近於0 。在水苔介質商業栽培模式下, 養液澆灌頻率為每週2次, 養液濃度為667 mg L') (Peters 20 N-20 P20s-20 K20) , 樹皮及其混合介質對蝴蝶蘭之栽培效益比水苔介質差,顯示此模式對樹皮及其混合介質之不適用性;在每週給肥相同指標下,不同之養液澆灌頻率及濃度條件下,樹皮及其混合介質對蝴蝶蘭生育之影響而言' 3種施肥處理中,以養液澆灌頻率為每週l次,養、液濃度為667 mg L') (Peters 20 N-20 P20s-20 K20) 之處理有利於蝴蝶蘭之生育表現, 且部份樹皮混合介質處理之蝴蝶蘭生育表現和水苔介質商業栽培模式處理並無顯著性差異(p<0.05)。 |
| 英文摘要 | In order to evaluate the possibility of using the commercial bark imported from New Zealand for cultivation of Phalaenopsis seedlings, the physical and chemical properties of bark were investigated. Orchid (Phal. Sogo Yukidian) seedling growth under different combinations of culture media, fertilization frequency and nutrient solution concentrations also were tested in the screen house. The results showed that the pH value of the bark ranging from 5.0 to 6.12 was not significantly different from that of sphagnum moss. However the electric conductivity (EC) and water holding capacity of the bark was lower than those of sphagnum moss. The growth performance of Phalaenopsis seedlings in bark and various mixed media was inferior to those in sphagnum moss when commercial fertilization frequency and concentration of nutrient solution (1 time per 2 weeks with 667 mg L^(-1)) were applied. When bark and various mixed media for growth of Phalaenopsis were tested with various fertilization frequency and concentrations of nutrient solution (1 time per week with 667 mg L^(-1), two times per week with 333 mg L^(-1) and 3 times per week with 222 mg L^(-1), it was found that the growth performance of plants with 1 time per week with 667 mg L^(-1) fertilization was superior to others. Under this fertilization condition, the growth performance of plants grown in bark with various media was not significantly different from that of sphagnum moss with commercial fertilization frequency and concentration of nutrient solution (1 time per 2 weeks with 667 mg L-1). |
