Description

Technical Field

[0001] The utility model relates to the technical field of deep-water fertilization of rod fertilizers, in particular to a deep-water fertilization device for rod fertilizers which can fertilize deeply in water. Background Art

[0002] Stick fertilizer is a high-concentration, high-performance compound fertilizer made by high-intensity mechanical pressure. When applied, a hole is directly made in the soil next to the plant to insert the stick fertilizer, and then filled with soil. Each subsequent watering will only melt the surface layer of the fertilizer. The use of slow-release technology allows nutrients to directly act on the roots of plants, improving the fertilization effect. When using stick fertilizer in water for fertilization, the diving depth is not easy to adjust, which affects the adaptability of fertilization.

[0003] The existing equipment has a relatively single insertion depth when inserting fertilizer sticks into the soil for fertilization in water, and cannot be easily adjusted in multiple ways. The stability after adjustment is low, and the fertilizer sticks are easily affected by the buoyancy of water during the fertilization process, resulting in the equipment being unable to insert the fertilizer sticks to the required position for fertilization, affecting the efficiency and practicality of the equipment's fertilization operation of the fertilizer sticks. Therefore, those skilled in the art have provided a deep-water fertilizer applicator for fertilizer sticks that can fertilize deep in water to solve the problems raised in the above-mentioned background technology.
