Description

Technical Field

[0001] The utility model relates to the technical field of strawberry planting equipment, in particular to a fertilizing device for strawberry planting. Background Art

[0002] Existing strawberry fertilization often involves burying fertilizer in the soil before transplanting the strawberries. However, because strawberries have short roots and a greater demand for water, most of the fertilizer flows away with the water as the staff irrigates the strawberries, resulting in fertilizer loss.

[0003] In order to improve the effect of fertilization, the existing practice is to start hole-fertilization for strawberries. A hole is made on the ridge of the strawberry, the height of the hole is higher than the root system of the strawberry, and fertilizer is poured into the hole. Drip irrigation is used, and the water dissolves the fertilizer and flows to the roots.

[0004] However, there are still some problems in the process of hole-fertilization. On a strawberry planting ridge, two rows of strawberries are often planted, and a hole is often made in the middle of the ridge. Because the soil around the bottom of the hole has different tightness, the seeping water tends to seep to the side with looser soil, so that the water or fertilizer seeping into the hole cannot flow evenly to the left and right sides, causing different rows of strawberries on the same ridge to obtain different fertilizer nutrients and grow differently. At the same time, the seeping water or fertilizer will also flow to the front and back, which will also cause a certain amount of fertilizer loss. Moreover, as the strawberry roots continue to grow deeper and stronger, the depth of hole-fertilization also needs to be adjusted according to the situation. The operation process is complicated and the fertilization effect is poor. Utility Model Content

[0005] The utility model aims to provide a strawberry planting fertilizing device, which not only enables fertilizer liquid to be applied to different parts of the root of the strawberry seedling, but also ensures that all parts of the root of the strawberry seedling can obtain equal fertilizer nutrients, thereby making the growth of the strawberry seedling more uniform. Moreover, since the planting cavity separates the growth area of ​​the strawberry seedling from the adjacent soil, the soil outside the planting cavity cannot obtain fertility and is therefore not easy to breed weeds, thereby greatly reducing the frequency of manual weeding, saving fertilizer, and greatly reducing the labor cost in the strawberry planting process.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A strawberry planting fertilization device comprises a cylindrical planting cavity, wherein the inner and outer walls of the planting cavity are hollow structures, the outer wall of the planting cavity is provided with a fertilizer inlet, the fertilizer inlet is connected to a fertilizer inlet pipe, and the inner wall of the planting cavity is evenly distributed with a plurality of fertilization inlets connected to the hollow structure between the inner and outer walls of the planting cavity and the inner cavity of the planting cavity.

[0008] By adopting the above technical scheme, the planting cavity is used to separate the growth area of ​​the strawberry seedlings from the adjacent soil, so as to avoid the waste caused by the infiltration of fertilizer after fertilization. When the strawberry seedlings need to be fertilized, the fertilizer liquid is transported to the fertilizer inlet through the fertilizer inlet pipe, so that the fertilizer liquid enters the hollow structure between the inner and outer walls of the cylindrical planting cavity, and is evenly sprinkled through a plurality of fertilizer ports on the inner wall of the planting cavity, so that the fertilizer liquid can flow evenly around the strawberry seedlings, not only can the fertilizer liquid be applied to different parts of the root of the strawberry seedlings, but also can ensure that the distance from each fertilization position to the root of the strawberry seedlings is equal, and ensure that the roots of the strawberry seedlings can obtain equal fertilizer nutrients, so that the growth of the strawberry seedlings is more uniform, and because the planting cavity separates the growth area of ​​the strawberry seedlings from the adjacent soil, the soil outside the planting cavity cannot obtain fertility, and therefore is not easy to breed weeds, which greatly reduces the frequency of manual weeding, not only saves fertilizer, but also greatly reduces the labor cost in the strawberry planting process.

[0009] The utility model is further configured as follows: a drainage port is provided at the bottom of the planting cavity.

[0010] By adopting the above technical solution, the drain port is used to discharge excess liquid in the planting cavity, which can effectively avoid excessive liquid accumulation in the planting cavity due to excessive fertilization or excessive watering, resulting in root necrosis of the strawberry seedlings, thereby greatly improving the reliability of strawberry planting.

[0011] The utility model is further configured as follows: one end of the fertilizer inlet pipe is connected to the fertilizer inlet port, and the other end of the fertilizer inlet pipe is connected to the fertilizer supply pipe.

[0012] By adopting the above technical solution, the fertilizer supply pipe is generally connected to the fertilizer liquid configuration box to supply fertilizer liquid to the fertilizer supply pipe. The fertilizer supply pipe can be connected to multiple fertilizer supply pipes to realize fertilizer supply operations in multiple planting cavities, so that multiple strawberry seedlings can be fertilized at the same time, greatly improving the fertilization efficiency.

[0013] The utility model is further configured as follows: a plurality of fertilizer ports are respectively arranged on the circumference of the planting cavity inner wall at different height sections, the fertilizer ports on the circumference of each height section are evenly spaced, and the size of each fertilizer port decreases from top to bottom.

[0014] By adopting the above technical scheme, the fertilizer ports on the circumference of the different height sections of the inner wall of the planting cavity can respectively realize the fertilization operation at different height positions of the strawberry seedlings, ensuring that the positions at different heights of the roots of the strawberry seedlings can obtain sufficient fertilizer liquid. Since the fertilizer liquid will penetrate downward under the action of gravity after being discharged from the fertilizer port, the size of each fertilizer port is reduced from top to bottom in order to allow the upper fertilizer port to sprinkle more fertilizer liquid and the lower fertilizer port to sprinkle less fertilizer liquid. The fertilizer liquid sprinkled from the upper fertilizer port will partially penetrate downward to compensate for the fertilizer liquid that is less sprinkled from the lower fertilizer port, so that the amount of fertilizer liquid in each part of the soil above and below is the same, thereby ensuring the uniformity of fertilizer effect at each part of the root of the strawberry seedlings above and below.

[0015] The utility model is further configured as follows: a fertilization depth adjustment mechanism is provided in the planting cavity, the fertilization depth adjustment mechanism includes an air bag arranged in a hollow structure between the inner and outer walls of the planting cavity for realizing fertilization at fertilization ports of different heights, the air bag is an annular structure matching the hollow structure between the inner and outer walls of the planting cavity, the bottom of the air bag is fixedly connected to the bottom of the hollow structure between the inner and outer walls of the planting cavity, and the inner cavity of the air bag is connected to the trachea.

[0016] By adopting the above technical scheme, the depth adjustment mechanism is used to control the fertilization depth according to the root length of the strawberry seedlings during the growth period of the strawberry seedlings, so that the strawberry seedlings can obtain uniform and sufficient fertilizer effect throughout the entire growth stage, that is: when the roots of the strawberry seedlings are relatively short, air is supplied to the airbag through the trachea, so that the airbag is filled and gradually fills the hollow structure between the inner and outer walls of the planting cavity, so that the fertilization port below the hollow structure between the inner and outer walls of the planting cavity is blocked and sealed by the airbag, and only the fertilization port below the airbag that is not blocked can be used for fertilization. As the strawberry seedlings continue to grow, their roots continue to lengthen in the depth direction. At this time, the airbag trachea is controlled to extract part of the gas, and as the volume of the airbag decreases, the fertilization ports blocked by it are opened in sequence from top to bottom, ensuring that the fertilization ports at deeper positions can also be used for fertilization, thereby ensuring that each part of the strawberry seedlings can obtain sufficient fertilizer liquid after the roots become longer.

[0017] The utility model is further configured as follows: one end of the trachea is communicated with the inner cavity of the airbag, the other end of the trachea is communicated with the air supply and exhaust pipes, and the air supply and exhaust pipes are connected to the air outlet of the fan.

[0018] By adopting the above technical solution, the forward and reverse rotation of the fan can be controlled to achieve the change of the wind direction of the exhaust port, so that the air supply and exhaust main pipes can supply or exhaust air to the air pipe, thereby realizing the inflation and exhaust operations of the airbag, with a simple structure and easy operation.

[0019] The utility model is further configured as follows: the implant cavity is in a cone shape that is larger at the top and smaller at the bottom.

[0020] By adopting the above technical solution, the planting cavity is set to be a cone-shaped cylinder with a larger top and a smaller bottom, which can guide the direction in which the fertilizer liquid penetrates downward, so that the fertilizer can penetrate as close to the strawberry seedlings as possible after being sprinkled from the fertilizer port, further improving the utilization rate of the fertilizer liquid and reducing the waste of the fertilizer liquid.

[0021] The utility model is further configured as follows: spiral blades are arranged on the outer wall of the implantation cavity.

[0022] By adopting the above technical solution, when the planting cavity needs to be removed from the soil after the strawberry planting is completed, the soil is easily compacted, making the planting cavity firmly embedded in the soil and difficult to remove, and it is relatively laborious. Therefore, a spiral blade is provided, and the compacted soil can be loosened by gently turning it, thereby making it easier to remove the planting cavity from the soil, and the soil can also be loosened during the removal process, killing two birds with one stone.

[0023] The utility model is further configured as follows: the edge of the spiral blade is serrated.

[0024] By adopting the above technical solution, the serrated setting makes it easier to rotate the planting cavity, further improving the efficiency of removing the planting cavity from the soil.

[0025] The utility model is further configured as follows: a horizontally extending boss is provided at a position of the outer wall of the implantation cavity higher than the spiral blades.

[0026] By adopting the above technical scheme, the boss is used to locate the burial depth of the planting cavity in the early stage of planting, ensuring the consistent planting height of the strawberry seedlings in the planting cavity, avoiding the strawberry seedlings from blocking each other due to inconsistent heights, resulting in uneven lighting and affecting the uniformity of the growth of the strawberry seedlings.

[0027] The beneficial effects of the utility model are:

[0028] 1. The utility model separates the growth area of ​​the strawberry seedlings from the soil adjacent to it through the planting cavity, thereby avoiding the situation in which waste is caused by the extravasation of fertilizer liquid after fertilization. When it is necessary to fertilize the strawberry seedlings, the fertilizer liquid is transported to the fertilizer inlet through the fertilizer inlet pipe, so that the fertilizer liquid enters the hollow structure between the inner and outer walls of the cylindrical planting cavity, and is evenly sprinkled out through a plurality of fertilizer ports on the inner wall of the planting cavity, so that the fertilizer liquid can evenly flow to the surroundings of the strawberry seedlings, not only can the fertilizer liquid be applied to different parts of the root of the strawberry seedlings, but also can ensure that the distances from each fertilization position to the root of the strawberry seedlings are equal, and ensure that the roots of the strawberry seedlings can obtain equal fertilizer nutrients everywhere, so that the growth of the strawberry seedlings is more uniform, and because the planting cavity separates the growth area of ​​the strawberry seedlings from the soil adjacent to it, the soil outside the planting cavity cannot obtain fertility, and is therefore not easy to breed weeds, which greatly reduces the frequency of manual weeding, not only saves fertilizer, but also greatly reduces the labor cost in the strawberry planting process.

[0029] 2. The utility model provides a drainage port at the bottom of the planting cavity to discharge excess liquid in the planting cavity, which can effectively avoid the situation where excessive liquid in the planting cavity due to excessive fertilization or excessive watering causes root necrosis of the strawberry seedlings, thereby greatly improving the reliability of strawberry planting.

[0030] 3. In the utility model, the fertilizer supply pipe is generally connected to the fertilizer liquid configuration box to supply fertilizer liquid to the fertilizer inlet pipe. The fertilizer supply pipe can be connected to multiple fertilizer inlet pipes to realize fertilizer supply operations in multiple planting cavities, so that multiple strawberry seedlings can be fertilized at the same time, greatly improving the fertilization efficiency.

[0031] 4. The fertilizer ports on the circumference of the cross sections at different heights of the inner wall of the planting cavity in the utility model can respectively realize the fertilization operation at different heights of the strawberry seedlings, ensuring that the positions at different heights of the root of the strawberry seedlings can obtain sufficient fertilizer liquid. Since the fertilizer liquid will penetrate downward under the action of gravity after being discharged from the fertilizer port, the size of each fertilizer port is reduced from top to bottom in order to allow the upper fertilizer port to sprinkle more fertilizer liquid and the lower fertilizer port to sprinkle less fertilizer liquid, and the fertilizer liquid sprinkled by the upper fertilizer port will partially penetrate downward to compensate for the fertilizer liquid that is less sprinkled by the lower fertilizer port, so that the amount of fertilizer liquid in the soil at various places above and below is the same, thereby ensuring the uniformity of fertilizer effect at various places above and below the root of the strawberry seedlings.

[0032] 5. The depth regulating mechanism in the utility model is used to control the fertilization depth according to the root length of the strawberry seedlings during the growth period of the strawberry seedlings, so that the entire growth stage of the strawberry seedlings can obtain uniform and sufficient fertilizer effect, that is: when the root of the strawberry seedlings is shorter, air is supplied to the air bag through the trachea, so that the air bag is filled and gradually filled in the hollow structure between the inner and outer walls of the planting cavity, so that the fertilization port below the hollow structure between the inner and outer walls of the planting cavity is blocked and sealed by the air bag, and only the fertilization port that is not blocked below the air bag can perform fertilization operation, as the strawberry seedlings continue to grow, its roots continue to lengthen in the depth direction, at this time, the air bag trachea is controlled to extract part of the gas, as the volume of the air bag decreases, the fertilization port blocked by it is opened in sequence from top to bottom, ensuring that the fertilization port at a deeper position can also perform fertilization operation, thereby ensuring that each part of the strawberry seedlings can obtain sufficient fertilizer liquid after the roots become longer.

[0033] 6. The utility model can realize the conversion of the wind direction of the exhaust port by controlling the forward and reverse rotation of the fan, so that the air supply and exhaust main pipes can supply or exhaust air to the air pipe, thereby realizing the inflation and exhaust operations of the airbag, with a simple structure and easy operation.

[0034] 7. The utility model sets the planting cavity as a cone-shaped cylinder with a larger top and a smaller bottom, which can guide the direction of the fertilizer liquid to penetrate downward, so that the fertilizer can penetrate as close to the strawberry seedlings as possible after being sprinkled from the fertilizer port, further improving the utilization rate of the fertilizer liquid and reducing the waste of the fertilizer liquid.

[0035] 8. The utility model makes it easier to take the planting cavity out of the soil by arranging spiral blades, and can also loosen the soil during the taking-out process, thus killing two birds with one stone.

[0036] 9. The boss arranged on the outer wall of the planting cavity in the utility model is used to locate the burial depth of the planting cavity in the early stage of planting, so as to ensure the consistent planting height of the strawberry seedlings in the planting cavity, avoid the strawberry seedlings blocking each other due to inconsistent heights, and cause uneven lighting, which affects the uniformity of the growth of the strawberry seedlings.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] like Figures 1-2As shown, a fertilization device for strawberry planting includes a cylindrical planting cavity 1, wherein the inner and outer walls of the planting cavity 1 are hollow structures, the outer wall of the planting cavity 1 is provided with a fertilizer inlet 2, and the fertilizer inlet 2 is connected to a fertilizer inlet pipe 3, and the inner wall of the planting cavity 1 is evenly distributed with multiple fertilizer inlets 4 connected to the hollow structure between the inner and outer walls of the planting cavity 1 and the inner cavity of the planting cavity 1.

[0043] Furthermore, a drainage port 5 is provided at the bottom of the planting cavity 1 .

[0044] Furthermore, one end of the fertilizer inlet pipe 3 is connected to the fertilizer inlet 2 , and the other end of the fertilizer inlet pipe 3 is connected to the fertilizer supply pipe 6 .

[0045] Furthermore, a plurality of fertilizer ports 4 are respectively arranged on the circumference of the inner wall of the planting cavity 1 at different height sections, and the fertilizer ports 4 on the circumference of each height section are evenly spaced, and the size of each fertilizer port 4 decreases from top to bottom.

[0046] Furthermore, a fertilization depth adjustment mechanism 7 is provided in the planting cavity 1, and the fertilization depth adjustment mechanism 7 includes an air bag 71 arranged in the hollow structure between the inner and outer walls of the planting cavity 1 for realizing fertilization at fertilization ports 4 at different heights. The air bag 71 is an annular structure matching the hollow structure between the inner and outer walls of the planting cavity 1, and the bottom of the air bag 71 is fixedly connected to the bottom of the hollow structure between the inner and outer walls of the planting cavity 1, and the inner cavity of the air bag 71 is connected to the trachea 72.

[0047] Furthermore, one end of the air pipe 72 is communicated with the inner cavity of the airbag 71, and the other end of the air pipe 72 is communicated with the air supply and exhaust pipe 73, and the air supply and exhaust pipe 73 is connected to the exhaust port of the fan.

[0048] Furthermore, the implant cavity 1 is in the shape of a cone that is larger at the top and smaller at the bottom.

[0049] Furthermore, spiral blades 8 are provided on the outer wall of the implantation cavity 1 .

[0050] Furthermore, the edge of the spiral blade 8 is serrated.

[0051] Furthermore, a horizontally extending boss 9 is provided on the outer wall of the implantation cavity 1 at a position higher than the spiral blade 8 .

[0052] The working principle of the utility model is as follows: first, a planting ditch with a width matching the outer diameter of the cylindrical planting cavity 1 is opened along the strawberry planting ridge, and then the planting cavities 1 are placed in the planting ditch at equal intervals and covered with soil to ensure that the planting cavities 1 remain upright after being fixed. After all the planting cavities 1 are fixed in turn, the fertilizer inlet pipe 3 and the air pipe 72 on the planting cavity 1 are connected to the corresponding fertilizer supply pipe 6 and the air supply and exhaust main pipe 73 respectively.

[0053] Then plant the strawberry seedlings in the planting cavity 1. When fertilization is needed, start the fan first to supply air to the air bag 71 through the air pipe 72, so that the air bag 71 is filled and gradually fills the hollow structure between the inner and outer walls of the planting cavity 1, and only the fertilizer port 4 below the fertilizer port 4 opposite to the root of the strawberry seedling is blocked by the air bag 71. Then control the fertilizer supply pipe 6 to supply fertilizer liquid, and the fertilizer liquid enters the hollow structure between the inner and outer walls of each planting cavity 1 through the fertilizer inlet pipe 3 connected to the fertilizer supply pipe 6 in turn, and is evenly sprinkled through the multiple fertilizer ports 4 that are not blocked above the inner wall of the planting cavity 1, so that the fertilizer is The liquid can flow evenly around the strawberry seedlings, which not only allows different parts of the roots of the strawberry seedlings to be applied with fertilizer liquid, but also ensures that the distances from each fertilization position to the roots of the strawberry seedlings are equal, ensuring that all parts of the roots of the strawberry seedlings can obtain equal fertilizer nutrients, thereby making the growth of the strawberry seedlings more even. In addition, since the planting cavity 1 separates the growth area of ​​the strawberry seedlings from the adjacent soil, the soil outside the planting cavity 1 cannot obtain fertility and is therefore not easy to breed weeds, which greatly reduces the frequency of manual weeding, saves fertilizer, and greatly reduces the labor cost in the strawberry planting process.

[0054] As the strawberry seedlings continue to grow, the roots of the strawberry seedlings continue to grow longer. The gas in the airbag 71 is appropriately extracted according to the length of the roots of the strawberry seedlings, so that the volume of the airbag 71 is reduced, so that the fertilizer openings 4 blocked by the airbag 71 are opened from top to bottom in sequence, ensuring that the fertilizer openings 4 at deeper positions can also perform fertilization operations, thereby ensuring that all parts of the strawberry seedlings can obtain sufficient fertilizer liquid after the roots become longer.

[0055] When the strawberries are ripe, the planting area needs to be changed. At this time, the planting cavity 1 needs to be removed from the soil. Since the soil is easy to compact, the planting cavity 1 is firmly embedded in the soil and is difficult to remove, and it is relatively laborious. Therefore, a spiral blade 8 is provided on the outer wall of the planting cavity 1, so that the compacted soil can be loosened by gently turning it, thereby making it easier to remove the planting cavity 1 from the soil, and the soil can be loosened during the removal process, killing two birds with one stone.
