From a perspective of agricultural machinery and agronomy combination, a method was proposed to analyze corn production mechanization system. Based on the analysis of background and conditions, an analysis framework of corn production mechanization system was put forward, which was focusing on technology integration, organizational integration and management integration. For technology integration, the available agricultural and agronomic technologies those can be combined in the process of production mechanization were analyzed. For organizational integration, the existing categories of service organizations of corn planting and agricultural machinery were summarized to analyze the integration idea and method of the combination of agricultural and agronomic technologies. For management integration, suggestions on resource management, task adjustment and process management were proposed to promote the corn production mechanization. 
