[0036] Traditional sand culture systems usually only use pure sand as the substrate. Although this single substrate has good drainage, its air permeability and nutrient retention ability are poor, and it cannot meet the growth needs of various plants. Due to the high permeability of sand, excessive water loss makes it necessary to irrigate frequently, increasing the consumption of water resources and management costs.

[0037] To solve the above problems, in an embodiment of the present application, a sand cultivation system is provided. In each cultivation tank, a waterproof layer is sequentially arranged from bottom to top, which can effectively prevent water from flowing into the substrate or underground, ensuring the effective absorption of water by plant roots. At the same time, a substrate layer is formed by multiple substrates, which can solve the problem of air permeability while ensuring sand cultivation. Meanwhile, a protective layer is arranged between the waterproof layer and the substrate layer to isolate the waterproof layer and the substrate layer and protect the waterproof layer from physical damage and chemical erosion.

[0038] Please refer to Figures 1 to 3 the embodiment, wherein the sand cultivation system includes: a substrate 100 and cultivation tanks 200, where Figure 2 and Figure 3 the embodiment respectively shows two different types of cultivation tanks 200. A cultivation area is formed on the surface of the substrate 100; a plurality of cultivation tanks 200 are arranged on the surface of the substrate 100 at intervals; wherein, the size of each cultivation tank 200 can be adjusted according to actual needs. In Figure 2 the embodiment, the cultivation tank 200 has a square structure, and the square cultivation tank 200 can be more evenly distributed in the entire cultivation area, suitable for large-scale cultivation. The number and layout of the cultivation tanks 200 can be adjusted according to actual needs to adapt to different cultivation requirements. In some embodiments, the cross-section of the cultivation tank 200 has a shape with a decreasing width from top to bottom, which is suitable for a long and narrow cultivation area, has the advantages of good drainage performance and space saving, and is particularly suitable for an environment that requires rapid drainage. For example, in Figure 3 the embodiment, the cross-section of the cultivation tank 200 can have a trapezoidal structure. The side walls of the trapezoidal tank gradually narrow, which can guide the plant roots to grow downward, promote the roots to penetrate deep into the substrate layer 220, and enhance the stability of the plants. Compared with a rectangular tank, the trapezoidal design reduces the material usage and cost while ensuring the cultivation area.

[0039] In Figure 2 or Figure 3In the embodiment, the waterproof layer 210 and the substrate layer 220 arranged successively from bottom to top in the planting groove 200 are shown. Among them, the waterproof layer 210 prevents water from flowing away to the base 100 or underground, ensuring the effective absorption of water by the plant roots. The first substrate layer 220 provides good drainage. The second substrate ensures sufficient air permeability and nutrient retention capacity. Optionally, the waterproof layer 210 includes a plastic film. Plastic films such as PVC films, HDPE films, etc., have a very low water vapor transmission rate, which can effectively prevent water from permeating from the substrate layer 220 to the base 100 or underground, ensuring that the plant roots can fully absorb water. High-quality plastic films can be used for a long time in harsh environments, reducing the need for frequent replacement and lowering the maintenance cost. Compared with other waterproof materials (such as asphalt rolls, rubber sheets, etc.), plastic films have a relatively low price and a long service life, with a relatively high overall cost-effectiveness.

[0040] Considering that the waterproof layer 210 is made of a plastic film (such as a PVC film or an HDPE film), although these materials have good waterproof performance, they are relatively fragile and vulnerable to physical damage. Sharp objects such as stones and plant roots in the substrate layer 220 may scratch or pierce the waterproof layer 210. The waterproof layer 210 not only needs to prevent water penetration but also needs to resist the erosion of various chemical substances. Therefore, a protective layer 230 for isolating the waterproof layer 210 from the substrate layer 220 is also provided between the waterproof layer 210 and the substrate layer 220 to protect the waterproof layer 210. By setting the protective layer 230, the service life of the waterproof layer 210 can be significantly extended, and the repair and replacement frequency caused by the damage of the waterproof layer 210 can be reduced. The protective layer 230 (such as a PE film or a non-woven fabric) can form a physical barrier between the waterproof layer 210 and the substrate layer 220, effectively preventing the sharp objects in the substrate layer 220 from damaging the waterproof layer 210. The protective layer 230 can select materials with good air permeability (such as non-woven fabrics), which can not only provide physical protection but also do not affect the drainage and air permeability of the substrate layer 220, ensuring the healthy growth of plants. Among them, in some embodiments, the PE film is generally selected with a thickness of 0.5 mm to 1 mm, which is adjusted according to the specific application scenario. The non-woven fabric is generally selected with a thickness of about 1 cm to ensure sufficient strength and air permeability.

[0041] The substrate layer 220 includes a sandy first substrate and a second substrate having a pore structure; optionally, the first substrate includes sand. Sand has high permeability and can quickly drain excess water to prevent waterlogging. Sand provides a stable growth environment for plant roots, preventing the soil from being too loose or compacted. River sand or sea sand can be selected. The second substrate includes cinder or other materials with a pore structure (such as perlite, vermiculite, etc.). Materials such as cinder have a rich pore structure inside, which can promote air circulation and improve the oxygen supply to the roots. These materials can store a certain amount of water and nutrients, reducing the need for frequent irrigation and fertilization. Among them, in addition to cinder, the second substrate can also be selected: perlite, a volcanic glass mineral, which forms light and porous particles after high-temperature expansion and has good air permeability and water retention. Or vermiculite, a natural mineral, which forms a porous structure similar to perlite after heating and expansion and has excellent air permeability and water retention.

[0042] Optionally, the first substrate and the second substrate are mixed in a preset ratio. According to different plant requirements and planting conditions, the first substrate and the second substrate can be mixed in a preset ratio. The following are some examples of mixing ratios. For example, for succulent plants or fleshy plants: the first substrate (sand): 70%, the second substrate (cinder or perlite): 30%. This ratio is suitable for plants that require good drainage and can effectively prevent root rot. For general flowers or vegetables, the first substrate (sand): 60%, the second substrate (cinder or vermiculite): 40%. This ratio provides good drainage while offering good air permeability and water retention, suitable for most common plants. For plants that require high water retention, the first substrate (sand): 50%, the second substrate (cinder or a mixture of perlite and vermiculite): 50%. This ratio is suitable for plants that require relatively high water retention, such as certain herbaceous plants or shrubs.

[0043] Optionally, please also refer to Figures 4 to 6 , a drainage part 300 is provided at the open end of each of the planting grooves 200. It is used to drain excess water, prevent waterlogging, and ensure the healthy growth of plant roots. In Figure 4 and Figure 5 the embodiments, the drainage parts 300 are respectively arranged at the top and bottom of the planting groove 200 and can be rectangular, circular or other shapes, specifically depending on the design and requirements of the planting groove 200. Adjust according to the size and drainage requirements of the planting groove 200. In some embodiments, by designing a reasonable drainage hole diameter and filtering device, matrix particles are prevented from entering the drainage pipeline and causing blockage. In Figure 6In the embodiment, the drainage part 300 and the planting trough 200 form a radial shape. By placing the drainage part 300 at the center of the surrounding planting trough 200, not only can the area of the substrate 100 be saved, but also a switching valve can be arranged in the drainage part 300 to store water in the drainage part 300 when water storage is needed and introduce it into the planting trough 200 when needed, avoiding waste.

[0044] Optionally, the depth of the drainage part 300 is greater than that of the planting trough 200. Before installing the planting trough 200, a drainage pipe deeper than the bottom of the planting trough 200 is pre-buried, and it is ensured that it is connected to the drainage holes at the bottom of the planting trough 200. Ensure that the drainage pipe has a certain inclination angle to help the water flow naturally to the predetermined discharge point by the action of gravity. An appropriate filtering device (such as a fine mesh) is arranged at the drainage inlet to prevent matrix particles from entering the drainage pipe and causing blockage. Increasing the depth of the drainage part 300 can effectively reduce the possibility of water accumulation in the planting trough 200, which is especially suitable for areas with heavy rainfall or frequent irrigation. Good drainage helps to maintain soil aeration and avoid the problem of root hypoxia caused by excessive moisture.

[0045] Optionally, please refer to Figure 7 and Figure 8 In the embodiment, the waterproof layer 210 covers the planting trough 200 and the rest of the planting area outside it. The waterproof measure is not limited to the planting trough 200 itself, but comprehensively protects the entire planting area. Extending the waterproof layer 210 to the area outside the planting trough 200 can provide more comprehensive waterproof protection and reduce the risk of groundwater seepage into the planting area. The large-area continuous waterproof layer 210 helps to improve the overall stability of the system and extend the service life. Further, the unified design of the waterproof layer 210 makes the inspection and maintenance work simpler and more efficient.

[0046] Optionally, in Figure 9 and Figure 10 In the embodiment, a humidity sensor is further arranged in the substrate layer 220, installed in the substrate layer 220, and used to monitor the humidity level of the soil or substrate in the planting trough 200 in real time. The sand cultivation planting system further includes a spraying mechanism 400 respectively arranged above each planting trough 200, and the nozzles 410 of each spraying mechanism 400 face the corresponding planting trough 200; the spraying mechanism 400 is communicatively connected to the humidity sensor and used to determine whether to spray water to the corresponding planting trough 200 according to the humidity value detected by the humidity sensor.

[0047] Specifically, in some embodiments, the humidity sensor continuously collects the humidity data of the substrate in the planting trough 200 and transmits this data to the control system (such as a central controller or a cloud platform) connected by communication. After receiving the data from the humidity sensor, the control system analyzes it according to a preset threshold (for example, the ideal humidity range) to determine whether the current humidity meets the plant growth requirements. If the humidity is lower than the set minimum value, the control system will issue an instruction to start the corresponding spraying mechanism 400 to spray water on the specific planting trough 200 until the humidity returns to the ideal range. Similarly, if the humidity exceeds the set maximum value, the system can pause spraying or adjust the spraying amount to prevent overwatering. By accurately measuring and regulating the humidity of each planting trough 200, overwatering or under-watering in the traditional irrigation method is avoided, and precise irrigation is achieved. There is no need for manual frequent inspection and adjustment of the watering amount, reducing the labor input.

[0048] Optionally, the plurality of planting troughs 200 are arranged in a straight line, an arc or a ring. The advantage of the straight-line arrangement is that the staff can easily move along the straight path, which is convenient for daily maintenance (such as checking the plant growth status, fertilizing, pruning, etc.). The straight-line arrangement helps to ensure that all plants can obtain relatively uniform light, reducing the problem of insufficient light caused by occlusion. The advantage of the arc arrangement is that in a limited space, especially on an irregularly shaped plot of land, the arc arrangement can make more effective use of every inch of land. The advantage of the ring arrangement is that all the planting troughs 200 are arranged around the center point, enabling the staff to monitor and manage the crops in all directions simultaneously from the central position, improving the management efficiency.

[0049] The above embodiments are only illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present disclosure should still be covered by the protection scope of the present disclosure.
