摘要：
PROBLEM TO BE SOLVED: To easily adjust a culture solution so as not to contain fertilizer components in more than a required amount regarding a hydroponic culture solution used in an artificial cultivation facility where environmental conditions are artificially controlled to cultivate crops.SOLUTION: The method for adjusting the hydroponic culture solution includes carrying out a first hydroponic test for obtaining the absorption characteristics of crops regarding one or more kinds of fertilizer components contained in the culture solution, and a second hydroponic test for obtaining a minimum culture solution concentration for holding an excellent growing state in the artificial cultivation facility where hydroponics of crops is actually carried out, and adjusting the culture solution based on these test results.COPYRIGHT: (C)2013,JPO&INPIT【課題】環境条件を人工的に制御して農作物の栽培を行う人工栽培施設において用いられる養液栽培用の培養液について、肥料成分を必要量以上に多く含むことのない培養液を簡易に調整する。【解決手段】培養液に含まれる1種又は2種以上の肥料成分についての農作物の吸収特性を得るための第一の養液栽培試験と、実際に農作物を養液栽培する人工栽培施設において良好な生育状態が保持される最小培養液濃度を得るための第二の養液栽培試験とを実施し、これらの試験結果に基づいて培養液の調整を行うようにした。【選択図】図15
