Technical Field

[0001] The present application relates to the technical field of soilless cultivation, and in particular to a soilless cultivation device. Background Art

[0002] Soilless cultivation is a cultivation method that does not rely on soil, but supplies nutrients required for plant growth through artificial substrates and nutrient solutions. The substrate plays a vital role in soilless cultivation. It not only provides physical support for plant roots, but also affects the supply of water and air, thereby affecting the growth and development of plants.

[0003] In the existing soilless cultivation system, substrate compaction is a common problem. Substrate compaction refers to the gradual loss of the original loose structure of the substrate during use, becoming compact, resulting in obstruction of water and air supply, poor root breathing, and ultimately affecting the normal growth of plants. It may also lead to uneven distribution of nutrient solution and increase the risk of disease.

[0004] In order to solve the problem of substrate compaction, a variety of methods have been proposed, including regular turning of the substrate and using substrate materials with good air permeability. However, these methods have certain limitations: 1. Regular turning of the substrate requires additional labor input, which increases management costs and labor intensity; 2. Although using materials with good air permeability can alleviate compaction, they are often more expensive and have poor water retention. Utility Model Content

[0036] See also Figure 1 , Figure 2 , Figure 3 A soilless cultivation device provided in an embodiment of the present application includes an outer cultivation container 10 with an opening at an upper end, an inner cultivation container 11 with an opening at an upper end is arranged in the outer cultivation container 10, and a cultivation matrix 12 is arranged in the inner cultivation container 11; a water retention space 13 is formed between the outer cultivation container 10 and the inner cultivation container 11, and the water retention space 13 is filled with water retention foam 14, and a plurality of through holes 15 connecting the inner cavity of the inner cultivation container 11 with the water retention space 13 are arranged on the wall of the inner cultivation container 11.

[0037] See also Figure 1 , Figure 2 , Figure 3 , the outer cultivation container 10 and the inner cultivation container 11 are both upper open structures surrounded by at least a bottom wall and a circle of side walls; the inner cultivation container 11 is arranged in the outer cultivation container 10 and supported on the bottom wall of the outer cultivation container 10, and a water retention space 13 is formed between the side walls of the two. The cultivation matrix 12 is an important component of the soilless cultivation technology, which is arranged in the inner cultivation container 11 and is used to provide the necessary fixed support and growth medium for the plants, which may include an inorganic matrix and an organic matrix. The water-retaining foam 14 is a porous material composed of a polymer, which has excellent water absorption and water retention properties. It is filled in the water retention space 13 and plays a role in water absorption and water retention. A plurality of through holes 15 are arranged on the side wall of the inner cultivation container 11, and the through holes 15 are used to connect the inner cavity of the inner cultivation container 11 with the water retention space 13.

[0038] A soilless cultivation device provided in an embodiment of the present application is used for soilless cultivation of plants. The specific cultivation process is: placing an inner cultivation container 11 in an outer cultivation container 10, placing a water-retaining foam 14 in a water-retaining space 13 between the inner cultivation container 11 and the outer cultivation container 10, placing a prepared cultivation substrate 12 in the inner cultivation container 11, planting plants in the cultivation substrate 12 and watering them, and excess water in the cultivation substrate 12 flows into the water-retaining space 13 through a through hole 15 on the wall of the inner cultivation container 11 and is absorbed and stored by the water-retaining foam 14; in this process, when too much water in the cultivation substrate 12 is lost, the water in the water-retaining foam 14 will also flow into the inner cultivation container 11 through the through hole 15 to replenish water to the cultivation substrate 12, keep the cultivation substrate 12 moist, and prevent the substrate from becoming hardened.

[0039] The embodiment of the present application provides a soilless cultivation device, which fills the water-retaining foam 14 in the water-retaining space 13 between the outer cultivation container 10 and the inner cultivation container 11. When the water in the cultivation matrix 12 is high, the water-retaining foam 14 is used to absorb and store the excess water and nutrients in the water in the cultivation matrix 12. When the water loss in the cultivation matrix 12 is serious, the water-retaining foam 14 is used to replenish the water and nutrients in the water into the cultivation matrix 12, so as to keep the cultivation matrix 12 moist and prevent the cultivation matrix 12 from becoming hardened due to drying, thereby effectively ensuring the sufficiency of water and nutrients for a long time, eliminating the tedious operation of continuous watering and supplementing nutrients. Compared with the existing method of regularly turning the matrix, the present application does not require additional manual input, reducing management costs and labor intensity; compared with the existing use of matrix materials with good air permeability, the present application not only reduces costs, but also has better water retention.

[0040] In some embodiments, see Figure 3, the projection of the water-retaining space 13 on the horizontal plane is an annular structure. For example, the projection of the water-retaining space 13 on the horizontal plane can be a circular ring or a square ring, etc. Of course, in other embodiments, the projection of the water-retaining space 13 on the horizontal plane can also be other shapes, which are not specifically limited here.

[0041] Exemplarily, the outer shape of the outer cultivation container 10 is cylindrical, and the outer shape of the inner cultivation container 11 is cylindrical; when the inner cultivation container 11 is placed in the outer cultivation container 10, a cylindrical water-retaining space 13 is formed between the two. For example, the diameter of the inner cavity of the outer cultivation container 10 is 25 cm and the height is 25 cm, and the diameter of the inner cavity of the inner cultivation container 11 is 20 cm and the height is 20 cm. A water-retaining foam 14 with a length of 75 cm, a width of 2 cm, and a height of 20 cm can be placed between the outer cultivation container 10 and the inner cultivation container 11. Multiple layers of through holes 15 are arranged from top to bottom on the wall of the inner cultivation container 11, and each layer of through holes 15 includes a plurality of through holes 15 uniformly arranged along the circumference of the inner cultivation container 11, and the diameter of each through hole 15 is 1 cm.

[0042] In some embodiments, the water-retaining foam 14 is an integral structure; when in use, it is only necessary to cut the corresponding size from the entire piece of water-retaining foam 14 according to the size of the water-retaining space 13. In other embodiments, the water-retaining foam 14 includes a plurality of foam blocks; when in use, it is sufficient to put a plurality of foam blocks into the water-retaining space 13 to fill the water-retaining space 13, which is more convenient and flexible to operate.

[0043] In some embodiments, the water-retaining foam 14 includes melamine foam. Melamine foam is a new type of foam plastic with a high open-porosity three-dimensional grid structure. Its chemical structure and three-dimensional network cross-linking system give it unique chemical and physical stability. It will not age or decompose in weak acid and weak alkali environments, and has no residual free formaldehyde. It has excellent water absorption and water retention properties during the high open-porosity period. Among them, 1g of melamine foam can absorb about 300g of water, and its sanitation can also meet food hygiene requirements. Of course, in other embodiments, the water-retaining foam 14 can also include polyurethane foam, ordinary sponge, etc.

[0044] In some embodiments, the cultivation substrate 12 includes peat. Peat has the advantages of being light, having good water retention, good air permeability, being free of pests and diseases, and having a high organic matter content. Of course, in other embodiments, the cultivation substrate 12 may also include inorganic substrates such as vermiculite, perlite, rock wool, sand, polyurethane, and may also include organic substrates such as rice husk charcoal and bark, which are not specifically limited here.

[0045] In some embodiments, at least two inner cultivation containers 11 are arranged in the outer cultivation container 10. By arranging at least two inner cultivation containers 11, not only can the space be maximized and the cultivation quantity per unit area be increased, but also the environment in each inner cultivation container 11 can be independently controlled, so as to facilitate personalized management of different crops or different growth stages of the same crop. Among them, the outer cultivation container 10 and the inner cultivation container 11 are made of ceramic, glass, plastic or wood.

[0046] In some embodiments, see Figure 4 The upper ends of the outer cultivation container 10 and the inner cultivation container 11 are provided with shielding plates 16 for shielding the water-retaining space 13. The shielding plates 16 are provided to shield the upper end of the water-retaining space 13, thereby preventing the water stored in the water-retaining foam 14 from evaporating and losing from the upper end of the water-retaining space 13, thereby further improving the water-retaining performance of the entire device.

[0047] In some embodiments, see Figure 4 The shielding plate 16 is provided with a positioning protrusion 17 extending into the water-retaining space 13. When the shielding plate 16 is placed on the upper ends of the outer cultivation container 10 and the inner cultivation container 11, the positioning protrusion 17 is stuck on the upper end of the water-retaining space 13, thereby preventing the shielding plate 16 from moving in the horizontal direction, thereby improving the stability of the shielding plate 16 after placement. Among them, the positioning protrusion 17 can be connected to the shielding plate 16 by bolts or adhesives, and the positioning protrusion 17 can also be an integrally formed structure with the shielding plate 16.

[0048] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
