[0002] Fertilization refers to the agricultural technical measure of applying fertilizer to the soil or spraying it on plants to provide the nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, improve soil fertility and increase economic benefits. Fertilization is essential in agricultural planting, so fertilization devices are needed in agricultural planting.

[0003] The patent with announcement number CN220383591U discloses an agricultural planting fertilization device, including a base plate, a storage box is fixedly installed on the top of the base plate, a water pump is fixedly installed on the front side of the storage box, a liquid inlet pipe is fixedly installed on the liquid inlet end of the water pump, the liquid inlet pipe is inserted into the interior of the storage box, a branch pipe is fixedly installed on the liquid outlet end of the water pump, a shunt pipe is fixedly installed on one end of the branch pipe, and a plurality of nozzles are fixedly installed on the bottom of the shunt pipe, a two-way screw rod is installed on the bottom of the base plate through two bearing seats for common rotation, a slider is symmetrically threaded at the positive and negative threads of the two-way screw rod, and two sliders are fixedly installed at the bottom of the base plate and at positions corresponding to the two sliders; the utility model props up the device by an electric push rod, and then rotates the two-way screw rod to make the roller move under the action of components such as the slider and the mounting rod, thereby achieving the effect of adjusting the spacing between the two rollers according to the spacing on both sides of the field ditch.

[0004] In the specific use of the above-mentioned prior art, although the distance between the two rollers can be adjusted according to the distance on both sides of the field ditch, since the width of the base plate is fixed, when the distance between the two rollers is reduced, the two sides of the base plate may collide with two adjacent planting sites, and the base plate will also block the rollers, making it inconvenient for the staff to control the moving direction of the rollers, which may easily cause the rollers to roll onto the crops on the planting site.
