Bark or aliflor is commonly used as growing media for conventional Cymbidium production to avoid diseases caused by wet media conditions, but these media require excessive water and leachate due to their macroporosity. Although several studies indicated peat-based substrate could also produce a quality Cymbidium, most growers are reluctant to use peat-based substrate due to water management difficulty. FDR sensor-based automated irrigation system enabled efficient water management for plant production, and this study utilized the system to investigate the optimal substrate moisture levels to produce young Cymbidium with coir dust as the substrate. One-year-old Cymbidium ‘Hoshino Shizuku’ plantlets were grown in 1,330 mL plastic pot at four levels of volumetric water content (θ); 0.25, 0.35, 0.45, and 0.55 m<sup>3</sup>·m<sup>-3</sup>. Each θ threshold set point for irrigation was determined in the range around easily available water (from ‑1 to ‑5 kPa) and water buffering capacity (from ‑5 to ‑10 kPa) for the coir dust. To maintain the θ threshold set point over the 42 weeks, an automated irrigation system with twelve FDR soil moisture sensors and twelve solenoid valves connected to a data logger and relay driver was installed. At harvest, the numbers of leaves and pseudobulbs, and chlorophyll content of the plants did not differ among ... 전체 초록 보기
