Self-made training equipment has been widely applied in institutions with vocational education activities, yielding positive results. This article provides an overview of the steps involved in designing, assembling, and using such equipment, as well as common errors encountered during the design, assembly, and usage processes of the self-made training equipment model: the Central System for Automatic Irrigation and Fertilizer Injection (Venturi). Additionally, I discuss the role and significance of automatic irrigation equipment in vocational training for Crop Cultivation and High-Tech Agriculture to meet the current development needs of agriculture.Self-made training equipment has been widely applied in institutions with vocational education activities, yielding positive results.
