The invention discloses a plant root system three-dimensional reconstruction method and system based on a ground penetrating radar. The method comprises the following steps: acquiring a radar image of a plant root through the ground penetrating radar; inputting the radar image into the target detection model to generate a corresponding radar hyperbolic image; obtaining position coordinates and radiuses of all root points of the plant through a geometrical relationship between preset sampling points and a plant root system; feature parameters between root points in adjacent scanning surfaces are calculated in MATLAB software according to the position coordinates of all the root points of the plant, a threshold value is set according to the feature parameters to define a search window, all the root points are connected through the search window, and an initial topological structure diagram is generated; optimizing, three-dimensional filling and smooth reconstruction are carried out on the initial topological st
