Brief introduction of digital agriculture

Digital agriculture-1997 was formally put forward by two academicians of the American Academy of Sciences and the Chinese Academy of Engineering. Refers to the intensive and information-based agricultural technology supported by geographical space and information technology. Digital agriculture refers to the organic combination of high and new technologies such as remote sensing, geographic information system, global positioning system, computer technology, communication and network technology and automation technology with basic disciplines such as geography, agronomy, ecology, plant physiology and soil science. So as to realize the real-time monitoring of crops and soil from macro to micro in the process of agricultural production, and realize the regular information collection of crop growth, development, pests and diseases, water and fertilizer conditions and the corresponding environment. The generation of dynamic spatial information system is to simulate the phenomenon and process in agricultural production, so as to achieve the purpose of rational utilization of agricultural resources, reducing production costs, improving ecological environment and providing crop products and quality. Digital agriculture is a modern agriculture that regards information as an agricultural production factor and uses modern information technology to visually express, digitally design and manage agricultural objects, environment and the whole process. Digital agriculture effectively integrates information technology with all aspects of agriculture, which is of great significance for transforming traditional agriculture and changing agricultural production methods.
