Description

Technical Field

[0001] This utility model relates to the field of controlled-release fertilizer bags, specifically a controlled-release fertilizer bag that facilitates root fertilization. Background Technology

[0002] In the fields of agricultural planting and horticulture, scientific fertilization is the core link to ensure the healthy growth of crops and improve yield and quality. As the key organ for nutrient absorption, the root system of crops can maximize nutrient utilization and reduce resource waste through precise fertilization in the root zone. However, the traditional fertilizer bags and fertilization methods that are currently widely used have many technical pain points in practical applications and cannot meet the needs of modern planting for efficient, precise and convenient fertilization. Existing fertilizer bags generally rely on manual fertilizer collection, which is cumbersome and inefficient. Growers need to open the fertilizer bag first, manually scoop or weigh the fertilizer, and then apply it to the soil surface or shallow layer through trenching, hole application, or other methods. This not only consumes a lot of manpower and time, but also severely restricts production progress, especially in large-scale plantations (such as orchards and vegetable greenhouses) where the daily fertilization area is limited. More importantly, this fertilization method cannot allow the fertilizer to reach the active area of ​​the crop roots. The fertilizer mostly stays on the soil surface and needs to be leached by rainwater or irrigation to slowly penetrate into the root zone. During this process, a large amount of nutrients are easily fixed by the soil, volatilized, or leached away by water. Meanwhile, existing fertilizer bags lack the ability to continuously supply fertilizer and control the amount of fertilizer, and cannot adapt to the nutrient requirements of crops at different growth stages. From the seedling stage to the growth stage to the fruiting stage, the demand and ratio of nutrients such as nitrogen, phosphorus and potassium vary significantly. However, traditional fertilizer bags are just a single storage container, and the fertilizer release rate depends entirely on the natural environment. They cannot actively adjust the amount of fertilizer supply according to the crop growth stage, which can easily lead to problems such as excessive nutrient supply in the seedling stage leading to excessive growth and insufficient nutrient supply in the later stage affecting yield. In addition, although some slow-release fertilizers can achieve continuous fertilization, they are mostly granular formulations with a fixed release rate. When used in combination with fertilizer bags, they still cannot flexibly adjust the fertilization rhythm and cannot meet the diverse planting needs. More importantly, the replacement of existing fertilizer bags after the fertilizer is exhausted is extremely inconvenient. Most fertilizer bags have a sealed structure or are in direct contact with the soil and stick together. When replacing them, it is necessary to clean the residual fertilizer and separate the soil first. It is not convenient to replace the fertilizer bags and continue fertilization. Therefore, it is necessary to design a slow-release fertilizer bag that is convenient for root fertilization to solve the above problems. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please refer to Figure 1-5 As shown, this utility model provides a slow-release fertilizer bag for easy root fertilization, including a body 1 of the slow-release fertilizer bag, a guide block 2 is fixedly attached to the inner side of the body 1 near the bottom, a discharge port 3 is integrally formed at the bottom of the guide block 2 near the middle, a sealing cap 4 is screwed onto the discharge port 3, and a fertilizer supply component for root fertilization can also be screwed onto the discharge port 3, and adjusting components for adjusting the amount of fertilizer are installed on both sides of the fertilizer supply component.

[0017] It should be added that the guide block 2 is made of rubber, and the discharge port 3 can be disassembled and opened and sealed by the screw-on sealing cap 4, so that the material in the body 1 can be discharged downward and sealed. After disassembling the sealing cap 4, the discharge port 3 can be installed with the fertilizer supply component, so that the fertilizer in the body 1 can be continuously supplied downward. The adjusting component can adjust the amount of fertilizer required according to the growth cycle of the crop, so as to avoid the fertilizer being too large or too small and affecting the growth status of the crop.

[0018] Specifically, the fertilizer supply component includes a telescopic tube 5 screwed to the bottom of the discharge port 3. One end of the telescopic tube 5 is screwed to a grounding rod 6. A fixing plate 7 is integrally formed on the outer side of the grounding rod 6 near the top. Multiple circumferentially arranged guide holes 8 are opened on the outer side of the grounding rod 6 near the bottom. Two handles 17 are fixedly installed on the top of the fixing plate 7. Fixing cones 18 are welded to the four sides of the bottom of the fixing plate 7. A limiting part 21 is integrally formed on the outer side of the fixing cones 18 near the bottom.

[0019] The ground-inserting rod 6 is hollow inside. The two ends of the telescopic tube 5 can be screwed to the discharge port 3 and the ground-inserting rod 6 respectively. The telescopic tube 5 can extend and retract according to the installation distance. The material flows through the discharge port 3 to the telescopic tube 5 and the ground-inserting rod 6 for fertilizer application. The multiple guide holes 8 outside the ground-inserting rod 6 can facilitate the fertilizer to be discharged directly to the crop roots for fertilization.

[0020] Furthermore, the four fixing cones 18 at the bottom of the fixing plate 7 can be inserted into the ground soil. The limiting part 21 on the outside of the fixing cone 18 can increase the contact area between the soil and the fixing cone 18, so that the four fixing cones 18 can limit and fix the planting pole 6, prevent the planting pole 6 from shifting, shaking or falling off, and improve the stability of the planting pole 6 when it is inserted into the soil to fertilize the plant roots.

[0021] More specifically, the adjusting component includes a movable cavity 9 located inside the fixed plate 7. An adjusting plate 10 is slidably connected to the inside of the movable cavity 9. A connecting strip 11 is fixedly connected to one side of the adjusting plate 10. A screw rod 12 is screwed onto the top of the connecting strip 11. A connecting plate 14 is rotatably connected to the top of the screw rod 12 via a fixing part 13. A locking rod 15 is fixedly connected to one side of the connecting plate 14. A plurality of evenly arranged locking slots 16 are opened on the top of the fixed plate 7 near both sides. A guide part 19 is integrally formed on the inside of the insertion rod 6 near the top. A guide block 20 is fixedly connected to the bottom of the connecting strip 11. The guide block 20 is slidably connected to the bottom of the movable cavity 9.

[0022] Furthermore, the cross-section of the adjusting disc 10 is arc-shaped, and the two adjusting discs 10 close to form a circle. The material guide part 19 is an inclined ring, which can guide the material downward. The distance between the two adjusting discs 10 changes, and fertilizer can be supplied according to the amount of fertilizer applied to the crop. The bolt rod can drive the connecting plate 14 to move up and down through the fixing part 13. The guide block 20 can guide and limit the connecting strip 11 to prevent the connecting strip 11 from deviating or shaking. Therefore, the connecting plate 14 can drive the locking rod 15 to insert or disengage from the locking groove 16 to lock and fix the adjusting disc 10, thereby improving the convenience and stability of adjusting the amount of fertilizer applied.

[0023] Working principle: First, remove the sealing cap 4, then screw the two ends of the telescopic tube 5 to the discharge port 3 and the ground rod 6 respectively. Then, the material in the body 1 flows through the discharge port 3 to the telescopic tube 5 and the ground rod 6 for fertilizer application. The multiple guide holes 8 outside the ground rod 6 facilitate the fertilizer to be discharged directly to the crop roots for fertilization. When the amount of fertilizer needs to be adjusted, the connecting bar 11 causes the adjusting plate 10 to slide within the movable cavity 9. At the same time, the connecting bar 11 causes the guide block 20 to slide at the bottom of the movable cavity 9, which changes the distance between the two adjusting plates 10. Alternatively, the distance of a single adjusting plate 10 can be changed. Then, the bolt rod is screwed and rotated, causing it to move downward through the fixing part 13 and the connecting plate 14. Simultaneously, the connecting plate 14 causes the locking rod 15 to insert into the locking groove 16 to lock and fix the adjusting plate 10.
