Abstract
Description
Technical Field
[0001] This utility model relates to the field of flower pot technology, and in particular to a layered structure for soilless cultivation. Background Technology
[0002] Traditional soilless cultivation techniques typically employ a single substrate layer or a simple hydroponic system, which suffers from uneven distribution of water and nutrients and insufficient root aeration, impacting plant growth efficiency. Existing technologies have attempted to improve cultivation through layered structures, but these are often complex or fail to balance moisture retention, aeration, and water supply, resulting in limited plant growth and inconvenient management and maintenance. Therefore, there is a need to design a cleverly designed soilless cultivation structure that balances moisture retention, aeration, and water supply to meet the needs of plant growth, while also allowing the planting pot to self-water, thus satisfying market demand. Utility Model Content
[0003] The purpose of this invention is to provide a layered structure for soilless cultivation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A hydroponic layered structure includes a planting pot containing a planting substrate and a water-absorbing rope. Plants are planted in the planting substrate, and a replenishing solution is delivered to the planting substrate through the water-absorbing rope. The planting substrate is divided into multiple areas, with plants planted in the planting layer and the water-absorbing rope placed in the water-saturated layer.
[0006] Furthermore, the area is divided into three layers: a water-saturated layer, a planting layer, and a moisture-retaining layer.
[0007] Furthermore, the water-saturated layer, planting layer, and moisturizing layer are arranged sequentially from left to right or from right to left in the planting pot, with the corresponding areas being arranged vertically or at an angle.
[0008] Furthermore, the water-saturated layer is vertically arranged on one side of the planting pot, and the planting layer and the moisture-retaining layer are arranged vertically on the other side.
[0009] Furthermore, the water-saturated layer, the planting layer, and the moisture-retaining layer are arranged sequentially from top to bottom in the planting pot.
[0010] Furthermore, the absorbent rope enters from the bottom or side wall of the planting pot and is placed in the water-saturated layer.
[0011] Furthermore, the absorbent rope enters from the bottom or side wall of the planting pot, passes through the moisturizing layer and the planting layer in sequence, and is placed in the water-saturated layer;
[0012] The absorbent rope is in the shape of a straight line, an L-shape, a Z-shape, or an N-shape. When the absorbent rope is N-shaped, it passes through the planting layer and the moisturizing layer again and exits the planting pot, with both ends placed in the replenishing solution.
[0013] Furthermore, the water-saturated layer is filled with an absorbent substrate, the planting layer is filled with an air-permeable substrate, the moisture-retaining layer is filled with a moisture-retaining substrate, the replenishing solution is placed in a replenishing basin or replenishing box, and the replenishing solution is transported to the planting basin by the absorbent rope, and gauze is placed between the planting layer and the moisture-retaining layer.
[0014] Furthermore, the bottom and / or sides of the planting pot are provided with ventilation holes for air circulation.
[0015] Furthermore, the vent holes are located in the moisture-retaining layer.
[0016] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0017] 1. This utility model achieves efficient water supply by precisely delivering the replenishing solution to the saturated layer through a water-absorbing rope. Combined with a layered design, the saturated layer, planting layer, and moisturizing layer achieve a gradient distribution of water to meet the needs of plants at different growth stages, avoiding root water accumulation or drought. The combination of the saturated layer, planting layer, and moisturizing layer takes into account water retention, aeration, and nutrient supply, significantly improving the survival rate and growth quality of plants. At the same time, the planting pot can absorb water itself to meet market demand.
[0018] 2. This utility model enhances the air permeability of each substrate layer by using a partitioned design with vertical, inclined or vertical arrangement, combined with air vents, to prevent root hypoxia; the moisture-retaining layer reduces water evaporation and improves resource utilization.

[0025] Example
[0026] refer to Figures 1 to 4 As shown, this utility model discloses a layered structure for soilless cultivation, including a planting pot 1. The planting pot 1 is provided with a planting substrate 11 and a water-absorbing rope 12. Plants are planted in the planting substrate 11. The water-absorbing rope 12 delivers replenishing liquid to the planting substrate 11. The planting substrate 11 is divided into multiple areas. The plants are planted in the planting layer 111. The water-absorbing rope 12 is set in the water-saturated layer 112.
[0027] The area is divided into three sections: a water-saturated layer 112, a planting layer 111, and a moisturizing layer 113. A gauze is placed between the planting layer 111 and the moisturizing layer 113. The gauze serves to separate the two areas, absorb water, further enhance moisture retention, and can be replaced as needed. The material of the gauze is not limited in this embodiment; it can be an absorbent material, such as pure cotton, or a corrosion-resistant material. The gauze can also serve as another moisturizing layer, increasing its thickness, such as 0.5-3 cm, to meet the moisturizing needs during periods of high evaporation in summer.
[0028] The water-saturated layer 112, planting layer 111, and moisturizing layer 113 are arranged sequentially from left to right or from right to left in the planting pot 1, with the corresponding areas being arranged vertically or at an angle, and the planting layer 111 being arranged between the two.
[0029] In this embodiment, the water-saturated layer 112, planting layer 111, and moisture-retaining layer 113 are arranged at an angle, allowing water to flow more easily to the planting layer 111 under the influence of gravity. The absorbent rope 12 enters the water-saturated layer 112 at an angle from the side wall of the planting pot 1, improving water transport efficiency. This angled, layered structure, combined with gravity, allows water to naturally permeate to the densely rooted area of the plants, while the moisture-retaining layer 4 slows evaporation, making it suitable for sloping terrain or vertical cultivation scenarios.
[0030] The water-saturated layer is vertically positioned on one side of the planting pot, while the planting layer and the moisture-retaining layer are positioned vertically on the other side.
[0031] The water-saturated layer 112, the planting layer 111, and the moisture-retaining layer 113 are arranged sequentially from top to bottom in the planting pot 1.
[0032] The water-saturated layer 112 is located at the top, facilitating gravity-assisted water infiltration; the planting layer 111 is in the middle, ensuring root aeration; and the moisture-retaining layer 113 is at the bottom, reducing water loss. The replenishing solution is transported upwards to the water-saturated layer 112 via the absorbent rope 12, and the water infiltrates downwards under gravity, sequentially wetting the planting layer 111 and the moisture-retaining layer 113, forming a self-sufficient water cycle and reducing the frequency of manual watering.
[0033] The water-absorbing rope 12 enters from the bottom or side wall of the planting pot 1 and is placed in the water-saturated layer 112.
[0034] The water-absorbing rope 12 enters from the bottom or side wall of the planting pot 1, passes through the moisturizing layer 113 and the planting layer 111 in sequence, and is placed in the water-saturated layer 112.
[0035] The water-absorbing rope 12 is in the shape of a straight line, an L-shape, a Z-shape, or an N-shape. When the water-absorbing rope 12 is N-shaped, it passes through the planting layer 111 and the moisturizing layer 113 again and exits the planting pot 1, with both ends placed in the replenishing solution. The replenishing solution is simultaneously transported to the saturated layer 11 through both ends of the water-absorbing rope 12. After the water diffuses in the substrate, some of it is reabsorbed through the return path of the N-shaped structure, forming an efficient water cycle, which is particularly suitable for the cultivation of plants with high water requirements.
[0036] The number of absorbent ropes in this embodiment is not limited.
[0037] The saturated layer 112 is filled with an absorbent substrate, the planting layer 111 is filled with an aerated substrate, the moisturizing layer 113 is filled with a moisturizing substrate, and the replenishing solution is placed in a replenishing basin or replenishing box, and the replenishing solution is transported to the planting basin 1 through the absorbent rope 12.
[0038] The water-saturated layer 112 is filled with a highly absorbent substrate, such as any one of the following: palm shell shreds, leaf shreds, bark shreds, sawdust shreds, plant straw, peat moss, mushroom residue, distiller's grains, organic fertilizer, petiole shreds, or coconut coir shreds. Absorbent ropes 12 are laid inside, entering from the side wall of the planting pot 1 and extending to an external replenishment container, pot, or box, for continuous water and nutrient delivery. The planting layer 111 uses a well-aerated substrate, which can be a mixture of pebbles and coconut coir, or any one of the following: perlite, vitrified microspheres, wood chips, fermented bark chips, slag, or crushed gravel, to anchor plant roots and provide an oxygen exchange environment. The moisture-retaining layer 113 is composed of a moisture-retaining substrate, such as sponge, pebbles, sphagnum moss, or a mixture of two or more of the above, to reduce water evaporation and maintain the humidity of the planting layer. It can be an organic or inorganic material with water-absorbing and moisture-retaining properties, or a mixture of both.
[0039] The planting pot 1 has ventilation holes on its bottom and / or sides. Through a zoned design with vertical, inclined, or top-to-bottom arrangement, combined with the ventilation holes, the permeability of each substrate layer is enhanced, preventing root hypoxia. The moisture-retaining layer 113 reduces water evaporation and improves resource utilization. The ventilation holes promote air exchange and prevent root rot. The Z-shaped layout of the water-absorbing ropes 5 ensures even water distribution, making it suitable for plants with high requirements for permeability (such as succulents and herbaceous plants).
[0040] This embodiment achieves efficient water supply. The replenishing solution is precisely delivered to the saturated layer 112 through the water-absorbing rope 12. Combined with the layered design, the saturated layer 112, the planting layer 111, and the moisturizing layer 113 achieve a gradient distribution of water to meet the needs of different growth stages of plants and avoid root waterlogging or drought. The combination of the saturated layer 112, the planting layer 111, and the moisturizing layer 113 takes into account water retention, aeration, and nutrient supply, significantly improving the survival rate and growth quality of plants. At the same time, the planting pot 1 can absorb water on its own to meet market demand.
[0041] This embodiment has the following four advantages:
[0042] 1. Precise water management: The layered design combined with absorbent ropes enables gradient distribution of water, avoiding the uneven moisture distribution problem of traditional hydroponics.
[0043] 2. Root health optimization: The combination of a breathable layer and a moisture-retaining layer ensures a balance of oxygen supply and humidity to the roots, reducing the risk of root rot.
[0044] 3. Flexible and adaptable structure: Supports various layouts such as horizontal, vertical, and inclined, adapting to different plant needs and cultivation environments.
[0045] 4. Low maintenance and high efficiency: The water-absorbing rope automatically delivers the replenishment liquid, reducing manual intervention and making it suitable for home planting and large-scale agriculture.
[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
