A rice planting sowing equipment according to claim 2, characterized in that: a pressure plate (51) is fixedly connected to the center position of the upper end surface of each of the furrowing plates (5), and the pressure plate (51) extends to one end of the frame (2) to form a T-shaped structure, and a limiting plate (52) matching the T-shaped structure of the pressure plate (51) is fixedly connected to the upper end surface of the support plate (23).

4. A sowing method for a rice planting sowing device according to any one of claims 1 to 3, characterized in that it comprises the following steps:

S1: Fertilizer is placed in the space behind the partition (61) of the material box (6), and rice seeds are placed in the space in front of the partition (61), and the frame (2) is pulled to drive the entire device to move. During the movement, when the notch (31) on the rotating wheel (3) passes under the feeding pipe (62), the material distribution mechanism is triggered, thereby simultaneously transporting the fertilizer and rice seeds into the notch (31);

S2: When the notch (31) rotates with the rotating wheel (3) to the ground, the pushing mechanism in the notch (31) pushes the fertilizer and the rice seeds into the rice field, thus completing the sowing;

S3: As the equipment moves, it drives the furrowing plate (5) to push away the soil between two adjacent rows of rice seeds, thereby forming a furrow.
