Intelligent control is the key core technology for the development of full mechanization of rice production to intelligence. This article summarized and analyzed the use of rice production machinery and mechanized operations at home and abroad from four aspects of rice cultivation,planting,field management and harvesting. It emphasized the application and development of intelligent technology in the full mechanization of rice production. It covered the plow deep intelligent adjustment and automatic flat plug tray technology,rice seedlings precision seeding performance detection and intelligent seeding technology,precise technology,water-saving irrigation technology,the technology of variable rate fertilization,weeding robot technology,plant diseases and insect pests and unmanned aerial vehicle remote sensing monitoring spraying technology,key components harvester monitoring and intelligent control technology,the impurity rate and on-line monitoring technology,automatic navigation and breakage driverless technology. The technical difficulties limiting the development of mechanization to intelligence in the whole process of rice production were pointed out. The development of multi-sensor information fusion is proposed to improve the intelligent perception ability of rice production machinery. The research and development of high-efficiency,precise and energy-saving intelligent equipment for rice must be innovated and accelerated. The high-end navigation system that integrates inertial navigation system and machine vision system must be explored. Promoting the intensive operation of general machinery and the sustainable development of modern agriculture is the key to realizing the mechanization and intelligence of the entire process of rice production.
