The invention provides a digitized wheat lodging-resistant experiment wind tunnel. The wind tunnel comprises four units of a wind tunnel body unit, a wind speed control unit, a wind speed determination unit, and an image automatic acquisition unit. The structural characteristics are that the wind tunnel body is integrally installed on a steel frame welded by rectangular steel tubes, an upper wall and side walls are formed by bending color plates which are filled with foam materials inside, two ends of the tunnel body and a front part and a rear part of a contraction section are provided with n-shaped steel frames, a lower layer of a baseplate is a wood board, and an upper layer is a galvanized iron sheet. Axial flow fans are installed on a frame which is welded by angle iron through screws, the fans being divided into three layers and each layer being provided with four fans. Width ratio of the tunnel bodies between an expansion section and the contraction section is 1 to 0.54. A rectification section is installed with barriers made of wood boards. An experiment section is 2.0 m by height, 1.3 m by width, and 7.0 m by length, and the top is installed with fluorescent lamps, and toughened glass observation windows are disposed on central positions of the side walls. Wind speed of the wind tunnel is 0-16 m/s, and is continuously adjustable, and the wind tunnel simulates wind gust velocity through adjusting time of acceleration and deceleration of the fans, so the wind tunnel can satisfy study of wheat wind dynamics and lodging-resistant wind speed research.
