In recent years, the development and innovation of no-tillage seeding machines have promoted the rapid progress of conservation tillage technology in China. With the development of precision agriculture and control technology, the research and application of row stubble avoidance, seeding rate and seeding depth monitoring and control technology have improved the intelligence of no-tillage seeding machines. Taking no-tillage seeding as an example, this paper introduces the research status of mechanical tactile technology, machine vision technology and modern control methods in no-tillage seeding row-follow stubble avoidance technology, expounds the application status of infrared detection technology, capacitance detection technology and image detection technology in no-tillage seeding rate monitoring, and introduces the research status of active and passive adjustment methods in no-tillage seeding depth monitoring. The future development direction of no-tillage seeding intelligence is prospected from the aspects of navigation fusion, algorithm and sensor research.
