The utility model provides a digitized wheat lodging-resistant experiment wind tunnel. The wind tunnel comprises a wind tunnel body, a wind speed control unit, a wind speed measuring unit and an image automatic acquisition unit. The structural characters are that wind tunnel body is integrally arranged on a steel rack formed by welding a rectangular steel pipe, the upper wall and the side wall are formed by bending colorized steel plates of which the middle parts are filled with foamed materials, and the two ends of the wind tunnel body and the front and back parts of a contraction segment are equipped with n-shaped steel racks; the lower layer of a bottom plate is a plank, and the upper layer is a zinc coated iron plate; three layers of axial-flow fans are arranged on a rack formed by welding an angle steel via screws, and four axial-flow fans are arranged on each layer; a wind tunnel body width between a diffusion segment and the contraction segment is 1: 0.54, and a rectification segment is equipped with a barrier made of the plank; the height of an experiment segment is 2.0 meters, the width is 1.3 meters, and the length is 7.0 meters; the top of an experiment segment is equipped with fluorescent lamps, the central position of the side wall is equipped with a toughened glass observation window. The wind speed of the wind tunnel can be adjusted continuously within a 0-16 m/s range, and the wind speed of the gust is simulated by adjusting the acceleration time and the deceleration time of the fans, and the wind dynamics and lodging resistant wind speed research demands of the wheat can be satisfied.
