| 中文摘要 | 本研究目的為確立介質溶液淋洗置換法(Pour-through,簡稱PT)運用於小花蕙蘭栽培之標準程序及最適合之PT淋洗液pH、EC值範圍,以供日後研究與應用之參考。試驗品種為虹河‘Hung-ho’及玉花‘Yu-hua’,試驗處理包括花生殼及花生殼混合小碎石計2種栽培介質,配合施用緩釋型肥料(N-P_2O_5-K_2O=14-12-14)0、3、6 g/pot/year等3級,合計6處理。由試驗結果顯示,玉花與虹河品種無論使用花生殼或花生殼混合小碎石栽培介質,3、6及9月PT淋洗液EC值均隨著肥料施用量增加而呈現增加之趨勢,PT淋洗液pH值均隨著肥料施用量增加而呈現降低之趨勢。其中PT淋洗液pH、EC值在不同品種及不同肥料施用量下,會呈現較明顯的差異。虹河及玉花品種在使用花生殼或花生殼混合小碎石等栽培介質下,多數植株生長特性在施用緩釋型肥料(N-P_2O_5-K_2O=14-12-14)3或6 g/pot處理間差異不顯著。綜合而言,虹河品種在使用花生殼或花生殼混合小碎石等栽培介質下,PT淋洗液EC值的適宜範圍在3、6及9月分別為0.24~0.42 dS.m^(-1)、0.15~0.28 dS.m^(-1)及0.37~0.68dS.m^(-1)。玉花品種在使用花生殼或花生殼混合小碎石等栽培介質下,PT淋洗液EC值的適宜範圍在3、6及9月分別為0.24~0.54 dS.m^(-1)、0.20~0.35 dS.m^(-1)及0.34~0.85 dS.m^(-1)。 |
| 英文摘要 | The objectives of this study were to set up a standard pour-through (PT) procedure and determining the optimum EC and pH ranges of the PT leachate for oriental cymbidium cultivation. The plant cultivars used in the study were 'Hung-ho' and 'Yu-hua'. Experiment was conducted with 2 kinds of substrate (peanut shells and peanut shells mixed with gravels) and 3 applied amounts (0, 3, 6 g/pot/year) of slow-release fertilizer (N-P_2O_5-K_2O = 14-12-14), totaled 6 treatments. The results show that EC values of the PT leachate increased and pH values decreased with increasing fertilizer applications in March, June, and September, among the plant cultivars and substrates treatments. The differences of the EC and pH values varied obviously in response to different cultivars and fertilizer application rates. The effects were not significant between the treatments of oriental cymbidium 'Hung-ho' and 'Yu-hua' using peanut shells and peanut shells mixed with gravels applying slow-release fertilizer (N-P_2O_5-K_2O = 14-12-14) 3 and 6 g/pot/year. In general, suitable EC values of the PT leachate of oriental cymbidium 'Hung-ho' in March, June and September were 0.24~0.42 dS.m^(-1), 0.15~0.28 dS.m^(-1) and 0.37~0.68 dS.m^(-1), respectively. Suitable EC values of the PT leachate of oriental cymbidium 'Yu-hua' in March, June and September were 0.24~0.54 dS.m^(-1), 0.20~0.35 dS.m^(-1) and 0.34~0.85 dS.m^(-1), respectively. |
