Description

Technical Field

[0001] The invention belongs to the technical field of agricultural hydroponic production, and in particular relates to a hydroponic device for crop seedlings. Background Art

[0002] Hydroponics is a new type of soilless plant cultivation method, also known as nutrient solution culture. Its core is to directly immerse the roots of the plants in the nutrient solution. This nutrient solution can replace the soil and provide the plants with water, nutrients, oxygen and other growth factors. For example, in agricultural production, when raising seedlings of crops such as barley, wheat, and vegetables, the crop seedlings are usually placed in hydroponic boxes and cultivated with nutrient solution to facilitate the rapid growth of the seedlings to a height suitable for planting. When adding undiluted nutrient solution, the seedlings are easily burned to death if they come into direct contact with the nutrient solution. In order to avoid the loss of seedlings, the seedling carrier is usually moved away together with the seedlings when adding the nutrient solution, and the seedlings are put back after the nutrient solution is filled and fully mixed and diluted. The hydroponic boxes or hydroponic plates commonly used in the prior art are not easy to remove, and the existing hydroponic devices are not easy to remove after the seedlings meet the requirements. The seedlings need to be taken out manually one by one, especially the seedlings with more developed root systems. When taking them out, it is easy to cause large-scale root damage, affecting the survival rate after planting, and such operation is time-consuming and labor-intensive, and the efficiency is very low. Therefore, it is necessary to design a hydroponic device that is convenient for carrying and removing seedlings. Summary of the invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a hydroponic device for crop seedlings.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A hydroponic device for seedlings of crops, comprising a hydroponic box and a hydroponic board installed at an opening at the upper end of the hydroponic box, wherein the two side edges of the hydroponic board in the width direction are respectively provided with downward matching eaves, and the two side edges in the length direction are respectively provided with handles; a limiting member for forming support for the lower end of the matching eaves is provided on the side wall of the hydroponic box, when the hydroponic board is installed in the hydroponic box, support is formed by the limiting member, and an air-permeable gap is formed between the lower surface of the hydroponic board and the upper end surface of the hydroponic box; a plurality of rows of plant holes are provided on the hydroponic board, and a certain planting basket is installed in each plant hole; the planting basket comprises a main growth section and a root restraint section, the inner diameter of the root restraint section is smaller than the inner diameter of the main growth section, an inwardly contracted supporting portion is provided at the lower part of the main growth section, the upper end of the root restraint section is connected with the supporting portion through an arc-shaped transition portion, and the outer wall of the upper end of the main growth section is provided with a convex ring, and the outer diameter of the convex ring is larger than the inner diameter of the plant hole.

[0006] Furthermore, the handle is in a plate shape and has a hollow hole in the middle thereof.

[0007] Furthermore, the outer diameter of the convex ring is 5-12 mm larger than the inner diameter of the plant hole.

[0008] Furthermore, the main growth section and the root restraint section both adopt a cylindrical structure.

[0009] Furthermore, the air permeability gap is 15-30 mm.

[0010] Furthermore, a limiting groove cooperating with the limiting piece is provided at the lower edge of the eaves to prevent the hydroponic plate from sliding down along the length direction of the hydroponic box.

[0011] Furthermore, the limiting member is a limiting block or a limiting column.

[0012] Furthermore, 2-3 limiting members are provided on the matching eaves on each side of the hydroponic board.

[0014] The hydroponic box created by the present invention has a detachable hydroponic plate installed on the upper end, and the hydroponic plate can be conveniently removed with the help of a handle. The planting basket installed on the hydroponic plate has a main growth section for carrying seedlings and a root restraint section for limiting the loose and scattered roots of the seedlings. During the growth of the seedlings, the roots are larger at the top and smaller at the bottom, making it easy to remove the seedlings, and reducing damage to the roots when removing the seedlings. At the same time, when planting seedlings, since the root system of the seedlings is compact, they can be conveniently transplanted into the soil or other cultivation devices, which is simple to operate and easy to implement.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] A crop seedling hydroponic device, such as Figures 1 to 8As shown, it includes a hydroponic box 1 and a hydroponic board 2 installed at the upper opening of the hydroponic box. The two sides of the hydroponic board in the width direction are respectively provided with vertical downward matching eaves 3, and the two sides in the length direction are respectively provided with handles 4. As an example, the handle is in the shape of a plate and has a hollow hole in the middle. A limiting member 5 is provided on the side wall of the hydroponic box for supporting the lower end of the matching eaves. When the hydroponic board is installed in the hydroponic box, the limiting member forms a support, and a breathable gap 6 is formed between the lower surface of the hydroponic board and the upper end surface of the hydroponic box. Usually, the breathable gap is 15-30mm. In practical applications, the designed breathable gap can better ensure the air exchange between the hydroponic box and the outside world to avoid hypoxia of the seedlings.

[0029] A plurality of rows of plant holes 7 are provided on the hydroponic plate, and a certain planting basket 8 is installed in each plant hole; the planting basket includes a main growth section 9 and a root restraint section 10, the inner diameter of the root restraint section is smaller than the inner diameter of the main growth section, and an inwardly contracted supporting portion 11 is provided at the lower part of the main growth section, and the supporting portion is formed in a shape similar to the bottom of a bowl, which can support the seedlings grown hydroponically and ensure the stability of the seedlings. At the same time, the root restraint section is used to restrain the roots of the seedlings to prevent the roots from being too fluffy, thereby reducing the difficulty of removing the seedlings from the hydroponic device and reducing the damage to the roots. When planting the seedlings, the root system of the seedlings is compact and can be conveniently transplanted into the soil or other cultivation devices without affecting the operation and the stability of the plants due to the scattered roots.

[0030] In an optional embodiment, an anti-slip structure is detachably installed on the outer wall of the main growth section below the hydroponic board. For example, the anti-slip structure includes an anti-slip ring 15, the outer diameter of which is larger than the inner diameter of the plant hole, and the distance between the anti-slip ring and the convex ring is 3-5 times larger than the thickness of the hydroponic board. When the seedlings are cultivated and need to be taken out, the hydroponic board can be directly lifted, and then the hydroponic board can be turned upside down. Holding the handle with both hands, the hydroponic board can be shaken up and down. Through the gravity of the seedlings themselves, and the convex ring and anti-slip ring of the planting basket collide with the hydroponic board back and forth to vibrate, the seedlings can be smoothly separated from the hydroponic board.

[0031] The upper end of the root restraint section is connected to the supporting part through an arc-shaped transition part 12, and the outer wall of the upper end of the main growth section is provided with a convex ring 13, and the outer diameter of the convex ring is larger than the inner diameter of the plant hole. Preferably, the inner wall of the convex ring is in the shape of a cone hole, with a large diameter at the upper end and a small diameter at the lower end, which will not hurt the seedlings and is conducive to the removal of the seedlings. Usually, the outer diameter of the convex ring is 5-12mm larger than the inner diameter of the plant hole. The main growth section and the root restraint section both adopt a cylindrical structure or a conical cylindrical structure, so that the seedlings and the roots of the seedlings are both large at the top and small at the bottom, which is conducive to the removal of the seedlings from the hydroponic device.

[0032] In an optional embodiment, a limiting groove 14 is provided at the lower edge of the eaves to cooperate with the limiting member, so as to prevent the hydroponic board from sliding down along the length direction of the hydroponic box and ensure that the hydroponic board has good stability. For example, the limiting member is a limiting block or a limiting column. 2-3 limiting members are provided on each side of the hydroponic board on the eaves.

[0033] The hydroponic box created by the present invention has a detachable hydroponic plate installed on the upper end, and the hydroponic plate can be conveniently removed with the help of a handle. The planting basket installed on the hydroponic plate has a main growth section for carrying seedlings and a root restraint section for limiting the loose and scattered roots of the seedlings. During the growth of the seedlings, the roots are larger at the top and smaller at the bottom, making it easy to remove the seedlings, and reducing damage to the roots when removing the seedlings. At the same time, when planting seedlings, since the root system of the seedlings is compact, they can be conveniently transplanted into the soil or other cultivation devices, which is simple to operate and easy to implement.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
