[0025] A device for identifying the lodging resistance of a rice population comprises a fixed plate 1. Two fixed plates 1 are provided. Two positioning plates 2 are fixedly connected to opposite ends of the two fixed plates 1. The front and rear portions of the lower ends of the two fixed plates 1 are fixedly connected to fixed cones 3. The front and rear portions of the upper ends of the two fixed plates 1 are fixedly connected to support rods 4. The upper ends of the four support rods 4 are interspersed with extension rods 5. The upper ends of the four extension rods 5 are commonly fixedly connected to a top plate 6. The left and right ends of the top plate 6 are fixedly connected to rain test assemblies 8. The lower end of the top plate 6 is fixedly connected to a wind test assembly 7.

[0026] In this embodiment, the rainwater testing assembly 8 includes a connecting plate 81, and three support tubes 82 are inserted and connected to the upper end of the connecting plate 81. The three support tubes 82 pass through one end of the connecting plate 81 and are fixedly connected to a water pipe 83. The lower part of the outer surface of the three water pipes 83 is fixedly connected to a number of nozzles 84, and the connecting plate 81 is fixedly connected to the top plate 6.

[0027] Through the above scheme: the rain test component 8 is used to perform a rain lodging resistance test on rice, the three support tubes 82 can respectively supply water to the three water pipes 83, and the multiple nozzles 84 can spray water to simulate the rain test process. The support tubes 82 on the two rain test components 8 are connected to the external water supply component, and the water volume of the multiple nozzles 84 is controlled by the external high-pressure equipment.

[0028] In this embodiment, the wind test assembly 7 includes a telescopic cylinder 71, and two telescopic cylinders 71 are provided. The output ends of the two telescopic cylinders 71 are commonly fixedly connected to a support frame 72, and the right end of the support frame 72 is fixedly connected to a drive motor 73. The output end of the drive motor 73 passes through a part of the support frame 72 and is fixedly connected to a round rod 75, and the round rod 75 is movably connected to the support frame 72 through a connecting shaft. A fan assembly 74 is sleeved on the outer surface of the round rod 75, and the two telescopic cylinders 71 are both fixedly connected to the top plate 6; the fan assembly 74 includes a plate body 741, and the upper left and upper right parts of the plate body 741 are fixedly connected to connecting rings 742, and the lower end of the plate body 741 is fixedly connected to several fan bodies 743, and the two connecting rings 742 are both fixedly sleeved on the round rod 75; there is no contact between the plate body 741 and the support frame 72.

[0029] Through the above scheme: the wind test component 7 can be used to test the wind resistance of rice. The two telescopic cylinders 71 are used to jointly push the use height of the support frame 72. The round rod 75 is driven to rotate by the driving motor 73. The angle of the fan component 74 fixedly connected to the round rod 75 can be rotated to improve the flexibility of the use angle of the fan component 74. The fan component 74 can be fixedly connected to the round rod 75 through two connecting rings 742. The wind can be blown by several fan bodies 743 to test the resistance of rice to lodging under wind blowing.

[0030] It should be noted that the present invention is a device for identifying the lodging resistance of a rice group. During use, first, four fixing cones 3 are used to firmly connect the device to the ground. These fixing cones 3 are ensured not to move or tilt by passing through four positioning plates 2 and tightening screws. Then, the connection lengths between the four support rods 4 and the four extension rods 5 are synchronously adjusted and fixed with screws to adjust the use height of the entire device. This ensures that the height of the device is adapted to rice at different growth stages so that accurate lodging resistance tests can be performed. The support pipes 82 on the two rainwater test assemblies 8 are connected to the external water supply assembly. In this way, the external water supply assembly can provide the required amount of water for several sprinklers 84. The water spraying amount of the sprinklers 84 is precisely controlled by an external high-pressure device to simulate rainfall conditions of different intensities and durations. This simulated rainfall can help evaluate the lodging resistance of rice under rain erosion. The fan assembly 74 is connected to the two connecting rings 74 through the two connecting rings 74. 2 is connected to the round rod 75. In this way, when the drive motor 73 drives the round rod 75 to rotate, the operating angle of the fan assembly 74 can be flexibly adjusted. By adjusting the angle of the fan assembly 74, wind forces from different directions can be simulated, thereby more comprehensively evaluating the lodging resistance of rice under different wind conditions. The two telescopic cylinders 71 jointly push the operating height of the support frame 72, thereby adjusting the height of the fan assembly 74. This height adjustment function enables the device to simulate the effects of different wind speeds and directions on rice, further improving the accuracy and flexibility of the test. After setting the height of the device, water supply system, and wind system, the test begins. First, rainfall conditions are simulated through the sprinkler 84 to observe the performance of rice under rain erosion. Then, the drive motor 73 and telescopic cylinder 71 are started, and the angle and height of the fan assembly 74 are adjusted to simulate the effects of different wind conditions on rice. The lodging of rice under simulated rainfall and wind conditions is observed and recorded to evaluate its lodging resistance.
