Abstract: The deep integration of the digital twin with agriculture will provide a new driving force for the digital transformation and upgrading of agriculture. Based on the data flow generated by the agricultural production system, the digital twin system can achieve intelligent management and regulation of the crop production system through real-time situational awareness, ultra-real-time virtual deduction and interactive feedback throughout the whole process. This paper  overviewed  the development of crop production system and its cognitive approaches, clarified the background, concept, connotation, basic components, and technical advantages of agricultural digital twin system, and raised the application scenarios and development strategies for the agricultural digital twin system, which provided reference for promoting the smart crop production in China.
