Shading treatment device and method for identifying shade tolerance of soybeans

The invention relates to the technical field of agricultural planting, in particular to a shading treatment device for shade tolerance identification of soybeans, which comprises a first frame, a second frame arranged on the surface of the first frame, a motor arranged on one side of the first frame, a mounting rod arranged at the driving end of the motor, and a positioning seat arranged on one side of the first frame. A linkage rod is slidably connected to the surface of the positioning seat, a limiting block is arranged at one end of the linkage rod, the limiting block is movably inserted into a limiting groove, and the limiting groove is formed in one side of the mounting rod; the device has the beneficial effects that the bottom face of the limiting clamping block does not make contact with the surface of the linkage rod any more, the whole linkage rod can be moved in the direction close to the positioning base, meanwhile, the handle is loosened, and the limiting clamping block is jacked by the spring on
