Description

Technical Field

[0001] This utility model relates to the field of apple seedling cultivation technology, and in particular to a directional fertilization device for apple seedling cultivation. Background Technology

[0002] The cultivation process of apple seedlings includes the following steps: sowing time and method. Spring sowing of apple rootstock seeds is usually carried out from late March to early April. Before sowing, the seeds need to be soaked and germinated. Soak the seeds in warm water at about 45℃ for 2 to 4 hours, or in water at 25℃ for 24 hours. Then mix them with sand and place them indoors or in a greenhouse at about 20℃. Germination will occur in 5 to 7 days. The sowing method is generally double-row strip sowing, where the seeds are evenly scattered and then covered with soil.

[0003] Root suffocation refers to the phenomenon where plant root growth is hindered, preventing free respiration and nutrient absorption, leading to slow or even stopped root growth. Soil compaction results in poor aeration, affecting root respiration. Long-term use of chemical fertilizers causes soil salinization and compaction. During the cultivation of apple seedlings, improper management leads to fertilizer loss and soil compaction, preventing healthy growth of apple seedlings and failing to meet the actual needs of apple seedling cultivation. Utility Model Content

[0004] This utility model discloses a directional fertilization device for apple seedling cultivation, which aims to solve the technical problem that improper management during the cultivation of apple seedlings leads to fertilizer loss and soil compaction, preventing the healthy growth of apple seedlings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A directional fertilization device for apple seedling cultivation includes an inner cylinder. A first storage tube is fixedly connected to the top edge of one side of the inner cylinder. A first sealing cap is threadedly connected to the top of the first storage tube. A first conduit is fixedly connected to the bottom of the first storage tube. Two diversion tubes are provided at the bottom end of the first conduit. Multiple diversion holes are provided on the inner surface of the diversion tubes. Multiple auxiliary holes are provided on the inner surface of the inner cylinder. A second storage tube is fixedly connected to the top edge of the other side of the inner cylinder. A second sealing cap is threadedly connected to the top of the second storage tube. A second conduit is fixedly connected to the bottom of the first storage tube. Connection holes are provided on one side of the first sealing cap and the second sealing cap.

[0007] The interior of the diversion tube is connected to the interior of the second conduit. The diversion holes are evenly arranged on the inner surface of the diversion tube. Multiple internal vent holes are respectively provided on the inner side of the inner cylinder near the positions of the first and second conduits.

[0008] In a preferred embodiment, the bottom of the inner cylinder is provided with multiple water guiding funnels arranged in a circular pattern, and multiple mounting plates are fixedly connected to the inner wall of the inner cylinder. The mounting plates are used to fix the soil inside, and multiple through holes are provided on the surface of the mounting plates.

[0009] The through holes are used for apple seedlings to grow roots and increase the adhesion of the apple tree roots. The bottom of the inner cylinder is fixedly connected with multiple friction columns, which are used to fix the inner cylinder to the soil and prevent the inner cylinder from sliding.

[0010] In a preferred embodiment, the top edge of the outer side of the inner cylinder is rotatably connected to an intermediate cylinder, the top edge of the outer side of the intermediate cylinder is rotatably connected to an outer cylinder, a plurality of rotating nails are respectively provided on the four sides of the intermediate cylinder, and a plurality of fixing nails are provided on the inner surface of the outer cylinder near the rotating nails.

[0011] The fixed nail and the rotating nail are staggered, and the end faces of the fixed nail and the rotating nail are respectively provided with sharp points, which reduce the friction between the fixed nail and the rotating nail and the soil.

[0012] A handle is fixedly connected to the upper surface of the intermediate cylinder, a plurality of external vent holes are provided on the surface of the outer cylinder, and a plurality of friction strips are fixedly connected to the outer surface of the outer cylinder.

[0013] As can be seen from the above, the directional fertilization device for apple seedling cultivation provided by this utility model has the following technical effects.

[0014] Firstly, a pit with the same diameter as the outer cylinder is dug, and the outer cylinder is placed in the pit. An apple sapling is placed inside the handle, and soil is covered inside the middle cylinder. The first and second sealing caps are rotated, and water and fertilizer are added to the first and second storage pipes, respectively. The water enters the distribution pipe through the first conduit and seeps into the soil inside the middle cylinder through multiple distribution holes, increasing the moisture for the apple sapling. The fertilizer enters the distribution pipe through the second storage pipe and the second conduit. The fertilizer slowly mixes with the water and seeps into the middle cylinder. Due to the airtightness of the bottom of the middle cylinder, it is difficult for water and fertilizer to penetrate deeper into the ground, thus achieving the effect of conserving water and fertilizer.

[0015] Secondly, because the middle cylinder and the outer cylinder can rotate relative to each other, the soil tends to clump together after prolonged use, leading to reduced air permeability. By turning the handle, the middle cylinder rotates relative to the outer cylinder. The multiple rotating nails and multiple fixing nails on the middle cylinder interact to crush the soil clumps, increasing the gaps between the soil in the outer cylinder and the middle cylinder. This improves the air permeability inside the middle cylinder and enhances the air permeability of the apple seedling roots. Attached Figure Description

[0023] The present invention discloses a directional fertilization device for apple seedling cultivation, which is mainly used in situations where improper management during the cultivation of apple seedlings leads to fertilizer loss and soil compaction, preventing the seedlings from growing healthily.

[0024] Reference Figure 1 — Figure 4A directional fertilization device for apple seedling cultivation includes an inner cylinder 1. A first storage tube 10 is fixedly connected to the top edge of one side of the inner cylinder 1. A first sealing cap 11 is threadedly connected to the top of the first storage tube 10. A first conduit 9 is fixedly connected to the bottom of the first storage tube 10. Two diversion tubes 19 are provided at the bottom end of the first conduit 9. Multiple diversion holes 20 are provided on the inner surface of the diversion tubes 19. Multiple auxiliary holes 21 are provided on the inner surface of the inner cylinder 1. A second storage tube 14 is fixedly connected to the top edge of the other side of the inner cylinder 1. A second sealing cap 13 is threadedly connected to the top of the second storage tube 14. A second conduit 15 is fixedly connected to the bottom of the first storage tube 10. A connection hole 5 is provided on one side of the first sealing cap 11 and the second sealing cap 13 respectively.

[0025] The interior of the diversion pipe 19 is connected to the interior of the second conduit 15. The diversion holes 20 are evenly arranged on the inner surface of the diversion pipe 19. Multiple internal vent holes 18 are respectively provided on the inner side of the inner cylinder 1 near the positions of the first conduit 9 and the second conduit 15.

[0026] In this embodiment, a pit with the same diameter as the outer cylinder 4 is dug, and the outer cylinder 4 is placed in the pit. An apple tree seedling is placed inside the handle 2, and soil is placed inside the middle cylinder 3. The first sealing cap 11 and the second sealing cap 13 are rotated, and water and fertilizer are added to the first storage pipe 10 and the second storage pipe 14, respectively. The water enters the distribution pipe 19 through the first conduit 9 and permeates into the soil inside the middle cylinder 3 through multiple distribution holes 20, increasing the moisture for the apple tree seedling. The fertilizer enters the distribution pipe 19 through the second storage pipe 14 and the second conduit 15. The fertilizer slowly mixes with the water and permeates into the middle cylinder 3. Due to the airtightness of the bottom of the middle cylinder 3, it is difficult for water and fertilizer to penetrate deeper into the ground, thus achieving the effect of conserving water and fertilizer.

[0027] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, the bottom of the inner cylinder 1 is provided with a plurality of water guiding funnels 22, which are arranged in a circular manner. A plurality of mounting plates 12 are fixedly connected to the inner wall of the inner cylinder 1. The mounting plates 12 are used to fix the soil inside, and a plurality of through holes are provided on the surface of the mounting plates 12.

[0028] The through holes are used for the rooting of apple seedlings to increase the adhesion of apple tree roots. The bottom of the inner cylinder 1 is fixedly connected with multiple friction columns 7. The function of the friction columns 7 is to fix the inner cylinder 1 to the soil and prevent the inner cylinder 1 from sliding.

[0029] In this embodiment, multiple internal ventilation holes 18 and auxiliary holes 21 increase the air permeability of the soil inside the intermediate cylinder 3 and the soil inside the outer cylinder 4. The design of the water funnel 22 allows a certain amount of water to be collected at the bottom of the intermediate cylinder 3, which will seep into the ground through the top of the water funnel 22 to retain a certain amount of water, but not too much, so as to prevent the apple tree from rotting.

[0030] Reference Figure 1 , Figure 2 ,and Figure 4 In a preferred embodiment, the top edge of the outer side of the inner cylinder 1 is rotatably connected to the middle cylinder 3, the top edge of the outer side of the middle cylinder 3 is rotatably connected to the outer cylinder 4, a plurality of rotating nails 17 are respectively provided on the four sides of the middle cylinder 3, and a plurality of fixing nails 16 are provided on the inner surface of the outer cylinder 4 near the rotating nails 17.

[0031] The fixed nail 16 and the rotating nail 17 are staggered, and the end faces of the fixed nail 16 and the rotating nail 17 are respectively provided with sharp points, which reduce the friction between the fixed nail 16 and the rotating nail 17 and the soil.

[0032] A handle 2 is fixedly connected to the upper surface of the intermediate cylinder 3, and multiple external vent holes 8 are provided on the surface of the outer cylinder 4. Multiple friction strips 6 are fixedly connected to the outer surface of the outer cylinder 4.

[0033] In this embodiment, pressing the outer cylinder 4 causes multiple friction strips 6 to adhere tightly to the inner wall of the pit, making the outer cylinder 4 in close contact with the pit. Soil particles enter the space inside the outer cylinder 4 through multiple external ventilation holes 8 on the outer cylinder 4. The external ventilation holes 8 increase the contact between the outer cylinder 4 and the external soil. The middle cylinder 3 is placed inside the outer cylinder 4. Since the middle cylinder 3 and the outer cylinder 4 can rotate relative to each other, the soil is prone to clumping after long-term use, resulting in reduced air permeability. By turning the handle 2, the middle cylinder 3 is driven to rotate. The middle cylinder 3 and the outer cylinder 4 rotate relative to each other. The multiple rotating nails 17 and multiple fixing nails 16 on the middle cylinder 3 interact to squeeze the soil clumps and crush them, increasing the gap between the soil between the outer cylinder 4 and the middle cylinder 3, making the air permeability inside the middle cylinder 3 better, thus increasing the air permeability of the apple seedling roots.

[0034] Working principle: In use, dig a pit with the same diameter as the outer cylinder 4, place the outer cylinder 4 into the pit, put an apple tree seedling inside the handle 2, and cover the inside of the intermediate cylinder 3 with soil. Rotate the first sealing cap 11 and the second sealing cap 13 to add water and fertilizer to the first storage pipe 10 and the second storage pipe 14 respectively. Water enters the distribution pipe 19 through the first conduit 9 and permeates into the soil inside the intermediate cylinder 3 through multiple distribution holes 20, providing moisture to the apple tree seedling. Fertilizer enters the distribution pipe 19 through the second storage pipe 14 and the second conduit 15, slowly mixing with the water and permeating into the interior of the intermediate cylinder 3. Due to the airtightness of the bottom of the intermediate cylinder 3, water and fertilizer cannot easily penetrate deeper into the ground, thus conserving water and fertilizer. Multiple internal ventilation holes 18 and auxiliary holes 21 increase the permeability of the soil inside the intermediate cylinder 3 and the outer cylinder 4. The design of the water funnel 22 ensures that the bottom of the intermediate cylinder 3 is confined. A certain amount of water is collected and seeps into the ground through the top of the water funnel 22, retaining a certain amount of moisture, but not too much, to prevent root rot in apple trees. Pressing the outer cylinder 4 makes the multiple friction strips 6 fit tightly against the inner wall of the pit, and the outer cylinder 4 is in close contact with the pit. Soil particles enter the space inside the outer cylinder 4 through the multiple external ventilation holes 8 on the outer cylinder 4. The external ventilation holes 8 increase the contact between the outer cylinder 4 and the external soil. The middle cylinder 3 is placed inside the outer cylinder 4. Since the middle cylinder 3 and the outer cylinder 4 can rotate relative to each other, the soil is prone to clumping after long-term use, which reduces the air permeability. By turning the handle 2, the middle cylinder 3 is driven to rotate. The middle cylinder 3 and the outer cylinder 4 rotate relative to each other. The multiple rotating nails 17 and multiple fixing nails 16 on the middle cylinder 3 interact to squeeze the soil clumps and crush them, increasing the gap between the soil in the outer cylinder 4 and the middle cylinder 3, making the air permeability inside the middle cylinder 3 better, which has the effect of increasing the air permeability of the roots of the apple seedlings.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
