Abstract:

In Xingan League, a large agricultural area of Inner Mongolia, crop observation is an indispensable part in agricultural production, and crop canopy height is an important parameter in crop growth observation. Mastering the change of crop canopy height can understand the development progress and growth situation of crops, which is of great significance to analyze crop growth status, carry out crop yield prediction, guide agricultural activities, and ensure food security. This paper mainly introduced the research status of crop canopy height in Xingan League of Inner Mongolia, especially the research progress of crop canopy height based on laser ranging technology. The automatic measurement results of crop canopy in Tuquan County of Xingan League in 2018 and 2019 were compared with the manual observation results, which verified the effectiveness and feasibility of the crop canopy height based on laser ranging technology in this region.

Key words: laser ranging, crop canopy height, crop observation, measurement results, comparative analysis
