Accelerating the application of artificial intelligence (AI) and other modern information technologies in agriculture is an urgent need for the development of modern agriculture, which will help promote the development of national rural revitalization strategy, digital village construction and smart agriculture. To deeply analyze the potential and direction of smart agriculture driven by AI technology, we reviewed the key technologies of agricultural AI and the research status of agricultural AI for planting, poultry, animal husbandry and agricultural product traceability and classification, analyzed the gap of agricultural AI technology at home and abroad as well as the international situation and challenge of agricultural AI technology in China, and proposed the countermeasures and suggestions for the development of agricultural AI in the future.
