Abstract: Development status of main conservation tillage agricultural machinery operation monitoring technologies such as straw coverage, no-tillage precision seeding parameters, and machine working area were summarized, and typical conservation tillage monitoring equipment was also analyzed．On this basis, combined with development requirements and application scenarios of conservation tillage, main problems faced by conservation tillage agricultural machinery operation monitoring technology were summarized, and development of productized, serialized and standardized conservation tillage agricultural machinery operation monitoring equipment that took into account different needs was proposed．To provide a reference for solving important bottleneck restricting development of conservation tillage, prospects and suggestions were put forward．
