PROBLEM TO BE SOLVED: To provide a unit-type hydroponic rack system for water cultivation of vegetables, fruits, and flowers to allow the plants to be displayed and admired on the outside of an apparatus and a system in consideration of provision of a choice, change, and flexibility to expansion in equipment, system specifications and configuration, in consideration of reduction of burden on cultivation-related work, preparation, and maintenance work, and inconsideration of addressing issues such as transplanting hydroponic cultivated plants and taking the same out to the outside.SOLUTION: The present invention provides a system in which: a cultivation nutrient solution storage device and a lighting device to be used as a light source for growth are unitized, and a nutrient solution tank, a nutrient solution circulation pump, and an air-generating device are connected with a tube, thereby enabling a highly flexible configuration, change and expansion of the system and various options can be adopted depending on the characteristics of the target plant, such as a sowing planting method, adjustment of a plant growing space, utilization of an auxiliary pillar and an auxiliary net, and the like. In the system, supply, circulation and replacement of a nutrient solution, reduction of work, and taking out an ornamental plant under cultivation to the outside of the system are also possible.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】野菜、果実、草花水耕栽培用として、装置、システムの仕様、構成における選択肢の提供、変更、拡張への柔軟性の確保、栽培関連作業、準備、整備作業の負担軽減に配慮し、装置、システム外部での展示、観賞を可能とするための、水耕栽培植物の移植、外部への持出しといった課題への対応にも考慮した、ユニット式水耕栽培ラックシステムの提供を目的とする。【解決手段】栽培養液貯留装置、及び育成の光源となる照明装置を、ユニット化し、養液タンク、養液循環ポンプ、エアー発生装置を、チューブで、接続、連結するといったシステム化を採用、自由度の高いシステムの構成、変更、拡張を可能とするとともに、播種植付方法、植物育成空間の調整、補助支柱、補助ネットの活用等、対象植物の特性により、各種選択肢の採用を可能とし、養液の供給、循環、交換、作業の軽減、育成中の観賞用植物のシステム外部への持出しにも対応可能な構造を提供する。【選択図】図1
