A hole-digging shovel (48) is provided below one end of the output shaft of the second rotary motor (46). The hole-digging shovel (48) is located at the lower end of the L-shaped frame (47). The step of digging holes on the seedbed surface includes: S601: Determine the height of the π-shaped frame (21) according to the height of the bed surface. At the same time, determine the spacing of the second pin holes (32) of the π-shaped frame (21) according to the predetermined plant spacing, so as to select a matching π-shaped frame (21). S602: According to the width of the seedbed made in step S200, insert the square rod (31) into the square groove (23). According to the width of the seedbed, move the support units (2) on both sides of the seedbed to the top of the walkway. Then connect the first pin hole (24) and the second pin hole (32) with pins to fix the hoisting unit (3) on the two support units (2). Multiple hoisting units (3) are also fixed in the same way. Then screw the first through hole (22) and the first screw hole (12) so that the two moving units (1) are fixed at the lower end of the two support units (2) respectively. S603: According to the predetermined row spacing, multiple hole-digging units (4) adapted to the row spacing and bed width are assembled at predetermined positions on each square bar (31), and the screw is threaded through the third through hole (42) and screwed into the third screw hole (44) to fix the hole-digging unit (4). S604: When digging holes in the seedbed, the second rotary motor (46) is lowered by the linear mechanism (45), and the digging shovel (48) is rotated by the second rotary motor (46) to dig holes. Multiple digging units (4) dig multiple holes at the same time. After digging a hole once, the first rotary motor (13) drives the roller (14) to rotate, so that the equipment moves to the next position to continue digging holes. After the digging of the entire seedbed is completed, the seedbed digging equipment is moved to the next seedbed to dig holes. S700: Seedling Management: Within 7 days after the seedlings emerge from the soil, cultivate and weed the seedbed. After the leaves unfold, pinch off the tips of seedlings with central leaves larger than 15cm every month. Thin the seedlings when pinching off the tips. Each time you thin the seedlings, first remove the seedlings with diseases, and then remove the seedlings with the lowest plant height of 5% to 10%.
