In this case, the fertilizer is directly discharged by using the fertilizer discharging pipe 302; the clutch motor 308 operates, the clutch lead screw 315 rotates, the clutch lead screw 315 drives the moving block 316 to move, the moving block 316 drives the driving bevel gear 303 to move through the moving plate 314, and the operation direction of the clutch motor 308 is controlled to make the driving bevel gear 303 move away from the driven bevel gear 304 to a set distance in the direction away from the driven bevel gear 304, and then the clutch motor 308 stops operating; during operation, first lower the fertilizer discharging pipe 302 to the required height (the height adjustment process is not described in detail, refer to Embodiment 4) to ensure that the fertilizer falls stably into the extremely narrow fertilizer groove when directly dropping from the fertilizer discharging pipe 302, thereby improving the fertilization effect.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the present invention.
