Abstract: This paper takes the integrated management information platform of irrigation process as the research object, and puts forward the design requirements of irrigation information platform according to the agricultural irrigation process. It uses mobile communication technology to establish an irrigation information platform that can interact with mobile terminal data. The platform includes geographic information database, historical information database and thematic database, and has information retrieval module and digital database According to the analysis module, irrigation prediction module and platform system management module, the platform information data query, modification, instruction sending and irrigation demand reservation can be achieved by using the mobile terminal. The test results of information interaction between the mobile terminal and the platform show that after the mobile terminal inputs the relevant parameters such as crop species, growth status and planting area, the information platform can use the set irrigation prediction model to analyze the irrigation demand and generate irrigation instructions. Users can make irrigation appointment according to the recommended irrigation scheme, which effectively improves the convenience of using the irrigation information platform At the same time, it has guiding significance for the intelligent promotion of irrigation information platform.
