7. A method for monitoring the growth of buckwheat seedlings in farmland, characterized in that: The method for monitoring the growth of buckwheat seedlings in farmland is applied to the system for monitoring the growth of buckwheat seedlings in farmland as described in claim 6, comprising the following steps: Step 1: by installing a temperature and humidity sensor in the mounting base (1), the temperature and humidity of the soil and air are monitored in real time, and then the image acquisition device (17) is used to collect image information of buckwheat pests and diseases and leaf characteristics, and the arc-shaped support plate (16) collects and supplies the power required by the equipment; Step 2: When it is necessary to measure the growth height of buckwheat, the synchronous shaft (32) is driven to rotate by the motor, so that the lap wheel (30) controls the lifting rope (28) to pull the square lifting block (8), so that the central mounting seat (14) drives the arc-shaped support plate (16) to descend, and when the lens of the image acquisition machine (17) is at the height of the buckwheat, the image data is collected in accordance with the scale of the marking plate (4), and after use, the image acquisition machine (17) is restored to the original height; Step 3: When a large amount of dirt and dust adheres to the surfaces of the flexible photovoltaic panel (34) and the high-transmittance glass cover (18), the electromagnetic adsorption block (27) is powered off. At this time, the toggle gear (20) drives the flip plate (15) to rotate through the motor, and then the flip plate (15) drives the high-transmittance glass cover (18) to rotate through the meshing teeth (21). Then, the rotating arc-shaped support plate (16) pushes the first cleaning strip (24) out of the alignment positioning groove (22). The lower end cleaning strip of the first cleaning strip (24) scrapes and cleans the flexible photovoltaic panel (34) on the upper end of the arc-shaped support plate (16) under the elastic action of the downward pressure spring (26). When the high-transmittance glass cover (18) rotates, the arc-shaped support plate (16) is always in contact with the high-transmittance glass cover (18), so that the surface of the high-transmittance glass cover (18) can be cleaned.
