Currently, new agri-tech has been developed and adapted for the cultivation of crops using smart farming technologies, e.g., plant factories and hydroponics. Kelp (), which has a high industrial value, was considered as an alternative to chemicals for its eco-friendly and sustainably wide use in crop cultivation. In this study, a fermented kelp (FK) was developed for use in hydroponics. The FK contained various free and protein-bound amino acid compositions produced by fermenting the kelp with . Supplementing FK as an aeroponic medium when cultivating ginseng sprouts (GSs) elevated the total phenolic and flavonoid contents. Additionally, seven ginsenosides (Rg1, Re, Rb1, Rc, Rg2, Rb2, and Rd) in GSs cultivated with FK in a smart-farm system were identified and quantified by a high-performance liquid chromatography-evaporative light scattering detector/mass spectrometry analysis. Administering FK significantly increased the ginsenosides in the GSs compared to the control group, which was cultivated with tap water. These results indicate the FK administration contributed to the increased accumulation of ginsenosides in the GSs. Overall, this study suggests that FK, which contains abundant nutrients for plant growth, can be used as a novel nutrient solution to enhance the ginsenoside content in GSs during hydroponic cultivation.
目前，新的农业技术已经得到开发，并适用于利用智能农业技术种植作物，例如植物工厂和水培法。海带具有很高的工业价值，因其在作物种植中具有生态友好且可持续的广泛用途，被视为化学品的替代品。在本研究中，开发了一种用于水培的发酵海带（FK）。FK含有通过用……发酵海带产生的各种游离和结合蛋白的氨基酸成分。在种植人参芽（GSs）时添加FK作为气培介质，提高了总酚和类黄酮含量。此外，通过高效液相色谱 - 蒸发光散射检测器/质谱分析，对在智能农场系统中用FK培养的GSs中的七种人参皂苷（Rg1、Re、Rb1、Rc、Rg2、Rb2和Rd）进行了鉴定和定量。与用自来水培养的对照组相比，施用FK显著增加了GSs中的人参皂苷含量。这些结果表明，施用FK有助于GSs中人参皂苷积累的增加。总体而言，本研究表明，含有丰富植物生长养分的FK可作为一种新型营养液，用于在水培过程中提高GSs中的人参皂苷含量。
