灌水技術對蝴蝶蘭類的生育、開花之影響

Effects of Various Irrigation Methods on Growth and Inflorescence Emergence in Phalaenopsis and Doriteanopsis

本研究報告研究商業蘭花生產時，介質內灌溉前後的pF值對花序發出的影響，以尋找有效的灌溉系統。pF值在2.0到0時灌溉，導致較多的葉片、較大的葉面積及花序發生率。頂端澆灌可得到較佳的生長及較高比例的花序發生率，且根部腐爛較低。以素燒盆配合底部灌溉及2公克的肥料（14N-12P-14K）可得到最大的葉面積及最高的花序發生率。

The effects of the pF value, before and after irrigation, were studied on inflorescence emergence to find the efficient irrigation methods for commercial culture of orchids. The pF values ranging from 2.0 to O at the time of irrigation resulted in more leaves, greater leaf areas, and higher rates of inflorescence emergence. Top-irrigation resulted in better growth and higher rates of inflorescence emergence with a fewer number of rotted roots. Plants under sub-irrigation and grown in clay pots, with 2 g fertilizer (14-12-14), had the greatest leaf areas and the highest rates of inflorescence emergence.
