[0002] Hydroponic devices can precisely adjust and provide various nutrients required for plant growth. By preparing nutrient solutions with specific components and concentrations, researchers can accurately control the uptake of macroelements such as nitrogen, phosphorus, and potassium, as well as microelements such as iron, zinc, and manganese by plants, meeting the needs of different plants at various growth stages. This helps to screen plant varieties with lower requirements for specific nutrients or higher utilization efficiency.

[0003] For example, the patent application No. "201821661490.X" entitled "A Hydroponic Device for Plant Seeds or Seedlings" describes a hydroponic device that can conveniently and efficiently cultivate plant seeds or seedlings, promote plant root growth, and allow for timely monitoring of seed germination status, root and seedling growth. It can be used for batch seed germination and screening experiments, integrating germination and seedling cultivation, simplifying experimental procedures and improving work efficiency. However, the device's fixing tube is placed directly in the mounting groove of the support plate without a fixing device. The fixing tube is prone to tipping over during collisions or movement, which may expose the plant roots inside the fixing tube, affecting the absorption of water and nutrient solution by the plant roots. Utility Model Content
