Description

Technical Field

[0001] This utility model belongs to the field of fertilizer applicator technology, specifically, it relates to a fertilizer applicator suitable for uniform hole application of citric acid-soluble fertilizer. Background Technology

[0002] Tobacco is a high-yield crop with high requirements for nutrients such as nitrogen, phosphorus, and potassium, and a long growing season (approximately 120-150 days), requiring a continuous supply of nutrients. Citrate-soluble fertilizers are those that are insoluble in water but soluble in a 2% citric acid solution (pH approximately 2.1). This pH value is similar to the pH of various organic acids secreted by plant roots and released into the rhizosphere soil, collectively known as root acids. Therefore, citrate-soluble components can be dissolved into ionic forms by plant root acids and then absorbed. These fertilizers have a slow-release effect, preventing fertilizer leaching, significantly enhancing fertilizer efficiency, improving fertilizer utilization, and reducing the adverse effects of fertilizer on soil physicochemical properties, making them excellent soil conditioners. Common examples include silicon fertilizers and humic acid fertilizers. Citrate-soluble fertilizers have low solubility in water but are readily soluble in citric acid, such as superphosphate and phosphate rock powder. Tobacco has wide adaptability, but some tobacco fields may experience problems such as soil compaction, low organic matter content, or high acidity. Currently, tobacco fertilization is mainly carried out by direct manual spraying. However, the soluble fertilizer applied by manual spraying is unevenly distributed in the soil, forming clumps that do not have a large enough contact area with the soil. As a result, it cannot be dissolved by hydrogen ions in the root zone and release its fertilizing effect. Some tobacco seedlings suffer from insufficient nutrition due to uneven fertilizer distribution, leading to slow growth and yellowing leaves, while other seedlings suffer from excessive fertilizer, resulting in excessive vegetative growth and uneven overall growth. Utility Model Content

[0003] In view of this, the present invention provides a fertilizer applicator suitable for uniform hole application of lycine-soluble fertilizer, which can solve the problems of uneven fertilizer application and small contact area with root soil in tobacco fertilization.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a fertilizer applicator suitable for uniform hole application of lycopene fertilizer, including a fertilizer box, a handle, a material cover, and a discharge hole. The fertilizer box is a hollow cylindrical structure. The handle is fixedly connected to the side wall of the fertilizer box. The material cover is detachably connected to the top of the fertilizer box. Multiple discharge holes are evenly arranged on the upper surface of the material cover. The fertilizer box is provided with a first through hole, and the material cover is provided with a second through hole. The first through hole and the second through hole are symmetrically arranged. A support part is fixedly provided on the outside of the first through hole. The support part is a cylindrical sleeve structure and is fixedly connected to the bottom surface of the fertilizer box.

[0006] Based on the above technical solution, the fertilizer applicator of this utility model suitable for uniform hole application of citric acid-soluble fertilizer can be further improved as follows:

[0007] Among them, a snap-fit ​​block is provided around the outer side of the second through hole. The snap-fit ​​block is fixedly connected to the material cover. The cross-section of the snap-fit ​​block is a U-shaped structure. The groove of the U-shape is adapted to the support part. The edge of the U-shaped groove is a smooth arc structure.

[0008] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the snap-fit ​​block between the support and the cover enables quick assembly and disassembly of the cover and the fertilizer box. The arc-shaped edge of the U-shaped groove reduces friction during snap-fitting and improves the smoothness of operation.

[0009] Furthermore, the discharge hole has an inverted frustum shape, and the diameter of the top surface of the frustum is 1.5 times the diameter of the bottom surface.

[0010] The beneficial effects of adopting the above-mentioned improved design are as follows: The larger top diameter reduces fertilizer accumulation within the discharge hole, preventing blockages caused by adhesion or clumping. The inverted frustum shape allows for proper diffusion of the fertilizer during discharge, preventing concentrated accumulation and ensuring even distribution around the root system. Compared to a cylindrical discharge hole, the inverted frustum shape reduces fertilizer splashing due to gravity, improving fertilization accuracy.

[0011] Furthermore, the inner wall of the discharge hole is provided with a spiral groove, the pitch of which is 0.2 times the diameter of the top surface of the frustum.

[0012] The beneficial effects of adopting the above-mentioned improved scheme are as follows: The spiral structure subjects the fertilizer to rotational force during the discharge process, avoiding blockage caused by adhesion or clumping, which is especially suitable for powdered or granular citrate-soluble fertilizers. Guided by the spiral grooves, the fertilizer falls in a spiral pattern, ensuring a uniform distribution around the discharge hole and preventing localized accumulation. The spiral motion allows the fertilizer to fall more stably into the soil, reducing splashing or deviation caused by gravity and improving fertilization accuracy.

[0013] Furthermore, the support section has an inner groove in the middle, which is a ring structure with an isosceles trapezoidal cross-section.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are: the design of the inner groove makes it convenient for users to apply force to disassemble and separate the fertilizer box and the cover.

[0015] Furthermore, two arc-shaped connecting parts are fixedly connected to the bottom surface of the material cover, and the distance between the connecting parts and the outermost edge of the material cover is the same as the thickness of the side wall of the fertilizer box.

[0016] Furthermore, an annular stop is provided on the inner side wall of the fertilizer box, and a triangular protrusion is provided at the top edge of the connecting part. The connecting part uses elastic deformation to engage the protrusion and the stop. The engagement gap between the protrusion and the stop is 0.5mm, and the inclined side of the protrusion and the inclined side of the stop are both rounded.

[0017] Furthermore, a guide slope is provided at the connection between the discharge port and the bottom surface of the fertilizer box, and the inclination angle of the guide slope is 30 degrees.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: The 30-degree inclination angle allows the fertilizer to enter the discharge hole more smoothly under the action of gravity, avoiding blockage caused by accumulation or adhesion. The inclined surface design reduces the residence time of fertilizer at the edge of the discharge hole, reducing the risk of clumping, and is suitable for highly adhesive citrate-soluble fertilizers. The inclined surface also allows the fertilizer to form a diffusion motion when entering the discharge hole, avoiding concentrated accumulation and improving the uniformity of fertilization.

[0019] Furthermore, there are two stops, which are symmetrically arranged, and two protrusions, which are symmetrically arranged. The length of the stops is greater than the length of the protrusions, and the distance between the two stops is greater than the length of the protrusions.

[0020] Furthermore, both the fertilizer box and the lid are made of transparent acrylic.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: The open structure allows for direct observation of the remaining fertilizer amount in the fertilizer box, avoiding insufficient or excessive fertilization due to blind spots. It also allows for clear observation of whether the fertilizer falls smoothly, enabling timely detection of blockages or clumping, thus improving fertilization efficiency.

[0022] Compared with existing technologies, the beneficial effects of the fertilizer applicator provided by this utility model for uniform hole application of citrate-soluble fertilizers are:

[0023] 1. By designing multiple discharge holes evenly distributed on the upper surface of the handle, precise and targeted fertilizer delivery can be achieved, avoiding fertilizer waste or localized over-dispensing caused by traditional broadcasting or strip application, ensuring that the fertilizer acts directly on the vicinity of the root system and reducing loss.

[0024] 2. Hole application is specially designed for lycopene fertilizers, which are fully mixed with the soil to improve nutrient absorption efficiency. It is especially suitable for the precise application of slow-release fertilizers or high-concentration fertilizers.

[0025] 3. Precise hole application avoids fertilizer loss or volatilization with water, reducing the amount of fertilizer needed while ensuring crop requirements, directly lowering production costs. Simultaneously, multiple discharge holes disperse fertilizer application, reducing soil salinity accumulation caused by fertilizer buildup, maintaining soil structure, and improving soil physical and chemical properties with long-term use.

[0026] 4. The porous design disperses fertilizer around the roots, preventing localized high-concentration fertilizer from burning the roots or inhibiting growth. The central perforation design provides space for the seedlings while ensuring that the fertilizer acts directly on the initial growth area of ​​the roots. Attached Figure Description
