Crop canopy assimilation measuring robot

The embodiment of the invention provides a crop canopy assimilation measuring robot. The crop canopy assimilation measuring robot comprises a first base beam, a second base beam, wheels and a box body; the two or more wheels are connected to the lower part of the first base beam and the lower part of the second base beam correspondingly; the inner left side box face of the box body is fixedly connected to the upper part of the first base beam, and the inner right side box face of the box body is fixedly connected to the upper part of the second base beam; the inner left side box face and the inner right side box face are fixedly connected with the top box face, and an inner front box door and an inner rear box door are rotatably connected with the top box face; the outer left side box face, the outer right side box face, an outer front box door and an outer rear box door can extend downwards into soil; and the box body is internally provided with a sensor box. In the advancing process of the crop canopy assimilation measuring robot, assimilation measuring of crop canopies is achieved, assimilation measuring of the crop canopies in the multiple positions can be achieved only through one equipment, the automatic degree of filed in-situ assimilation measuring of crops is increased, the measuring cots is lowered, and meanwhile, natural growth of the crops is not affected.
