| Abstract: |
| [Purpose] In conjunction with the advancement of research in alfalfa intelligent management，the particular application of small unmanned aerial vehicle and ultrasonic detection in alfalfa intelligent management was presented to give ideas for remote diagnosis of precision agriculture and large-scale alfalfa production.[Method] Taking alfalfa as the research object and in shertaranong pasture，Hulunbuir City，Inner Mongolia as the research area，on the basis of summarizing the current research and application status of Alfalfa intelligent management，the data acquisition and application of Unmanned aerial vehicle and ultrasonic in alfalfa field are carried out.[Result] According to research，when compared to satellite unmanned aerial vehicle in a crop，it appears that the identification and estimation accuracy and speed demonstrated obvious advantages，which is the premise of alfalfa wisdom management data acquisition and analysis，from the representative of the unmanned aerial vehicle for alfalfa canopy height information of DSM data can greatly increase clover，alfalfa form three-dimensional modeling accuracy，alfalfa relative height estimate The capture of key characteristics in real-time during alfalfa growth improves the reliability of the results.[Conclusion] This paper summarized the current state of research on alfalfa intelligent management，discussed the benefits and drawbacks of existing research findings，and proposed a method for obtaining accurate data on alfalfa under various conditions by combining high-resolution images and ultrasonic sensors collected by unmanned aerial vehicle. The accompanying alfalfa management decision support system will give users alfalfa growth，yield forecast，real-time irrigation and fertilization management techniques based on this technology. |
