Abstract: In modern agriculture, agricultural producers need to know the farmland environment and the growth state of crop in a real-time, accurate and comprehensive manner, and make corresponding analysis, induction and decision of obtained information. Intelligent sensing and analysis technology of agricultural information plays an indispensable role in modern agriculture. In this review, we discussed two aspects of agricultural intelligent sensing and information analysis technology, focused on the research progress of agricultural information intelligent perception technology and agricultural information analysis method based on agricultural internet of things and big data at home and abroad, introduced the application of intelligent decision-making technology based on agricultural information in agricultural machinery and equipment intellectualization. The problems existing in application of agricultural sensors were summarized. Some suggestions were put forward for the development of agricultural information perception, information analysis technology, agricultural database technology and intelligent decision-making technology to provide a reference for the development of intelligent agriculture in future.
