Description

Technical Field

[0001] The invention relates to the technical field of agricultural tools, and in particular to a fertilizing device with a soil turning structure for agricultural planting. Background Art

[0002] At present, agricultural fertilizer spreaders mainly spread liquid fertilizers and solid fertilizers. After the soil in the field is plowed by the rotary tiller, the tractor's traction head replaces the plowing equipment with a fertilizer spreader. This plowing and fertilizing method requires turning the soil and fertilizing to be divided into two steps, which prolongs the duration of farming to a certain extent. In addition, for compound fertilizers, fertilization cannot be carried out directly after turning the soil, and fertilization must be carried out after a period of time, which also leads to the inconsistency of farming.
