以養液循環之潮汐灌溉系統栽培盆花，可省水省肥，避免養液流失而汙染環境。本研究於潮汐灌溉或傳統澆灌下，以逆滲透水配成0%、25%、50%、75%和100% (電導度值分別為0.0、0.5、1.0、1.5 和2.0 dS·m-1)強生氏營養液(Johnson’ssolution)濃度，探討灌溉方式與養液濃度對火鶴盆花‘粉冠軍’生長及開花之影響。結果顯示以潮汐灌溉栽培之植株生長較傳統澆灌者佳，兩種灌溉方式皆以施用25%營養液濃度處理者具較多葉片及花朵。潮汐灌溉處理之植株有較高之花朵乾重質量比(mass fraction)。葉片之氮、磷、鉀濃度隨施用營養液濃度提高而增加，而葉片鎂濃度隨施用養液濃度提高而下降。施用50%營養液濃度使總葉片之巨量元素含量飽和。以1 介質:2 水萃取法(體積比)分析結果顯示，潮汐灌溉處理之上層介質電導度值高於傳統澆灌處理者。兩種灌溉方式下，施用75%和100%營養液濃度之中下層介質電導度值超過0.75 dS·m-1，增加葉緣壞疽之葉數及耳部褪色之佛焰苞數。

Recycled nutrition in ebb-and-flow (E-F) system can reduce water and fertilizer usage to avoid fertilizer leaching and water pollution. The present study investigated the effects of five (0%, 25%, 50%, 75%, and
100%) Johnson’s solution concentrations on growth and flowering of Anthurium ‘Pink Champion’ under E-F or hand-watering system. Results showed that plants grew better under E-F than hand-watering. For both
irrigation methods, the best leaf and flower growth occurred in plants with 25% nutrient solution treatment.The ratio of flower dry weight to total dry weight was higher in E-F than in hand-watering. Leaf N, P, and K
concentrations increased, while leaf Mg decreased, as solution concentration increased. Leaf macro-element contents saturated in plants with 50% or higher nutrient solution concentrations. Electrical conductivity (EC) values of the upper medium portion were higher under E-F than hand-watering treatment as measured with 1 medium : 2 water extraction method (by volume). For both irrigation methods, plants exhibited more necrotic leaves and discolored spathes when applied with 75% or 100% nutrient solution, with EC values > 0.75 dS·m-1 of the middle and bottom medium portions.
