The work aims to drive college students to participate in food and agriculture education activities, improve their food and agriculture knowledge reserves, develop healthy eating behaviors, and promote a healthy lifestyle. Questionnaire survey and user interview were used to investigate the cognition and behavior status of college students on food and agriculture, as well as the motivation and demand for participation in food and agriculture education activities. Based on the activity theory level, the experience map and service platform system of food and agriculture education activities of college students were constructed through SPSS data analysis. The target, situation, emotion, pain spot and opportunity of food and agriculture activities of college students were comprehensively analyzed. Accordingly, a design strategy of food and agriculture education activities of college students was put forward. A food and agriculture activity platform was built, centered on college students' associations. Simultaneously, the design of sustainable, shared, online and offline food and agriculture education activities was carried out. Activity elements of the activity theory are collected. Game-like food and agriculture challenge tasks and experience evaluation are integrated. A community-driven platform of food and agriculture activities is established, thus promoting the continuous experience of college students and developing a healthy eating habit.
