10. A method for using a device for detecting wheat lodging resistance comprises the following steps: S1: First, the supporting bottom box (1) is moved as a whole to a designated detection position, and then two fixing members (3) are fixed inside the soil to fix the supporting bottom box (1) as a whole, and a plurality of conical air outlet pipes (10) correspond to the wheat to be detected; in, When conducting the test, the air pump inside the second protection box (16) is started, and the air pump generates gas and inputs it into the air storage box (35) through the air delivery pipe (20). The gas entering the air storage box (35) is input into the air storage pipe (9) through three connecting pipes (36), and finally discharged through three conical air outlet pipes (10) to blow toward the wheat. By continuously increasing the power of the air pump, the wind resistance of the wheat is detected, and then the lodging resistance of the wheat under different wind forces is detected, thereby improving the accuracy of the detection; S2: Then, the motor inside the first protection box (14) is started to rotate forward and reverse continuously, and the motor drives the threaded rod (28) to rotate, and the threaded rod (28) drives the movable sleeve (27) and the first slider (26) to reciprocate forward and backward, thereby driving the movable plate (15) as a whole to reciprocate forward and backward, thereby blowing air to a whole row of wheat. By moving the front and rear positions of the plurality of conical air outlet pipes (10), the whole row of wheat can be indirectly blown, thereby testing the lodging resistance of the wheat under unstable wind conditions; S3: When it is necessary to simulate the lodging resistance of wheat when the wind blows obliquely from above, firstly, the two first multi-stage telescopic cylinders (4) are started, and the two first multi-stage telescopic cylinders (4) drive the two first support plates (5) to move upward as a whole. After moving to the designated position, the two second multi-stage telescopic cylinders (6) are started, and the telescopic ends of the two second multi-stage telescopic cylinders (6) push the third support plate (13) to move forward as a whole through the rectangular block (33) and the two third slide blocks (34). After moving to the designated position, the servo motor (11) is started, and the servo motor (11) drives the second support plate (13) to move forward as a whole through the third slide blocks (34) connected thereto. The second connecting shaft (37) drives the second gear (25) to rotate rightward, and the second gear (25) drives the air storage pipe (9) to rotate downward as a whole through the first gear (23) and the first connecting shaft (21), and stops after rotating to a specified position, and then starts the air pump inside the second protection box (16), and then cooperates with the horizontal moving device to test the lodging resistance of wheat when the wind blows obliquely from above, so as to further improve the accuracy of the detection. By arranging the vertical moving device and the horizontal moving device, two testing methods of facing the wind and oblique wind can be adopted, and the lodging resistance of wheat in different environments can be tested.
