Diseño y construcción de un germinador de esquejes y semillas de petunias y ciclamen

Abstract

The present graduation project focuses on the design and construction of a germinator for petunia and cyclamen cuttings and seeds. It began with a preliminary study of current germination methods focused on ornamental plants, taking into account the design of the structure, temperature, humidity, and ventilation, all aimed at obtaining the suitable characteristics for this project's design. Once different alternatives were identified, the design of all machine components was carried out, including ventilation, irrigation, and temperature systems. The parts composing the machine's structure were manufactured using mechanical design software such as Inventor. Subsequently, mechanical, electrical, and control assembly took place. Additionally, programming of the HMI (Human Machine Interface) control was performed using Nextion and Arduino, specifying how the system will work depending on the selected seed on the screen, ensuring better control over the system, including its respective inputs and outputs. This user interface will allow controlling the system's temperature, humidity, and ventilation while monitoring its real-time operation. Finally, various functional tests were conducted, comparing them with traditional seed germination methods. Errors that could affect the final germination process results will be corrected. All this is done to ensure the proper functioning of the system and achieve an innovative project in the field of floriculture.
