Abstract: With the development of modern science and technology research and theory of agricultural water saving,water-fertilizer irrigation are moving towards fine quantization, intelligent. This paper proposed the conception of smart irrigation system based on knowledge engineering（KBE）, and developed the decision support using techniques and methods of knowledge engineering, and integrated research results and expert knowledge of water-fertilizer irrigation in a system combining with computer network,intelligent reasoning and artificial intelligence and other modern high-tech. The system included database, model base, knowledge base, intelligent decision, visual query module and so on, combined expert experience and extensive knowledge by computer program,and simulates agricultural experts analysis with reasoning and interpretation mechanisms, under the help of data mining,machine learning and artificial intelligence technology to realize precision irrigation decision to improve the flexibility,accuracy and practicability of irrigation.

Key words: knowledge engineering, decision support, intelligent irrigation
