Description

Technical Field

[0001] The present invention belongs to the technical field of fertilization operation equipment, and particularly relates to an adjustment device and method for a ditching, fertilizing and backfilling integrated fertilizer applicator. Background Art

[0002] Fertilization operation equipment is a mechanical device or tool used to quantitatively and evenly apply fertilizers (solid, liquid or gaseous) into the soil or crop growth area according to agronomic requirements. Its core function is to improve fertilization efficiency, reduce manual labor, optimize fertilizer utilization rate, and promote crop growth.

[0003] Currently, the existing fertilization operation equipment cannot be adjusted during ditching for fertilization. During fertilization, it only ensures that fertilizers are applied on the bottom wall of the ditch, but not on the side walls of the ditch, resulting in a relatively poor final fertilization effect, with some positions not being penetrated by fertilizers and a poor fertilization effect. Moreover, when covering the soil after fertilization, it cannot break up and cut the soil to prevent large lumps of soil, causing some positions not to be covered, and it cannot detect the humidity of the soil during covering, directly covering the soil, which is likely to cause soil caking.
