In the process of China's agricultural modernization, especially agricultural machinery modernization, in terms of equipment, we've chose the way that foreign imports (and domestic research) with the combination of self-developed, in the software, it is difficult to fully apply this approach, the specific reasons are: the modernization of China's agriculture development model is diversified, it is difficult to find a unified management model, even in the scale of operations of the representative state-owned farms and the abroad farms are also very different management models. Due to various types of growth models of biological complexity, diverse climatic and geographical environment factors, coupled with the characteristics such as long cycle of agricultural production, high input, high-risk, and decentralized management, industrial management mode it is very difficult to apply. Moreover, the application of modern management tools is also difficult to quantify the benefits, leading to the current research and application are in a state of comparatively dropped behind. Combination the development of "Farm agricultural machinery informatization management system in The network integration system of digital agriculture of Heilongjiang province", Heilongjiang August First Land Reclamation University Digital Agriculture Project Team carried out case studies and experiments in a few more advanced farms (Red Star Farms, Seven Stars Farm, etc.) in Heilongjiang Province. In order to facilitate the unified management of the farm machinery operation, the agricultural machinery operation management system was achieved through a form of a web site design. With the support of precision agricultural technique, which include information management, farm machinery job scheduling, agricultural machinery performance standards and the accounting standard of the workload, the supply of fuel and spare parts, maintenance organizations and reminders, statistics analysis of the technical and economic indicators, financial accounting, as well as the necessary network meeting support systems, etc. To integrate the analysis and design of the informatization management network system of a farm, the efficient path of the farm machinery management modernization of a farm should be researched, in this paper, some details were discussed in the research and constructive foundation of agricultural machinery management modernization, the roles and actions of farm machinery informatization management network system in agricultural modernization, description of the issue of the farm machinery informatization management network system, the design of internal modular structure,external network system interface, open source questions and the improvement path to follow, etc.
