[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model with reference to the drawings in the present utility model. Obviously, the described embodiments are some, but not all, embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0022] The following will describe the nutrient soil column of the present utility model in combination with Figure 1 Describe the nutrient soil column of the present utility model.

[0023] As Figure 1As shown in the figure, the present utility model provides a nutrient soil column 1, which includes: a column body 11, a nutrient core (not shown in the figure), and a drip irrigation pipeline 12. The column body 11 is provided with a cultivation cavity 111 with an open top. The nutrient core is arranged in the cultivation cavity 111 for cultivating plants. The drip irrigation pipeline 12 is inserted into the column body 11 for communicating with an external water supply pipeline.

[0024] In this embodiment, by providing the cultivation cavity 111 on the column body 11, the column body 11 is used as a cultivation container for accommodating the nutrient core and plants. The nutrient core is used for cultivating plants, and the nutrient core can provide sufficient nutrients for the growth and survival of plants to extend the maintenance cycle of plants. It can be understood that the column body 11 is mainly made of soil, which can ventilate to the plant roots in the nutrient core, can also cooperate with the nutrient core to provide part of the nutrients for plants, and at the same time will not pollute the environment. In addition, by inserting the drip irrigation pipeline 12 communicating with the external water supply pipeline into the column body 11, the maintenance personnel can control the external water supply pipeline to supply water to the drip irrigation pipeline 12, and the drip irrigation pipeline 12 can drip irrigate the inside of the column body 11 to supplement water for the nutrient core and plants.

[0025] The nutrient soil column 1 of the present utility model, by providing the cultivation cavity 111 on the column body 11 as a container for accommodating the nutrient core and plants, has better air permeability, can also cooperate with the nutrient core to provide nutrients for plants, and is more environmentally friendly at the same time. By arranging the nutrient core in the cultivation cavity 111 of the column body 11 to cultivate plants, it can provide sufficient nutrients for the growth and survival of plants to extend the maintenance cycle of plants and reduce the maintenance frequency of the maintenance personnel. At the same time, by inserting the drip irrigation pipeline 12 communicating with the external water supply pipeline into the column body 11, the maintenance personnel only need to turn on and off the external water supply pipeline to realize the drip irrigation of the column body 11, the nutrient core and plants, without the maintenance personnel approaching the plants for irrigation, and the maintenance operation is more convenient and safe, effectively solving the problems of time-consuming, laborious and dangerous irrigation and maintenance of plants in vertical greening in the prior art.

[0026] Specifically, the column body 11 can be designed into any shape according to actual needs, and usually can be designed into a cylinder or a prism. Similarly, the cultivation cavity 111 can also be set into any shape such as a cylindrical cavity or a prism cavity.

[0027] Specifically, in some embodiments, such as Figure 1 As shown in the figure, the drip irrigation pipeline 12 is arranged at the top of the column body 11.

[0028] In this embodiment, by arranging the drip irrigation pipeline 12 at the top of the column body 11, the drip irrigation pipeline 12 can drip irrigate the top of the column body 11, and the dripping water droplets can penetrate downward along the column body 11, so that the water can fully penetrate into the column body 11 and the nutrient core to supplement the water in the nutrient core and enable the plants to grow and survive better.

[0029] Optionally, in some embodiments, the nozzle at one end of the drip irrigation pipeline 12 can be inserted into the column 11 from the top of the column 11, so as to directly introduce moisture into the column 11, making it difficult for the moisture to slide outside the column 11, thereby avoiding waste of moisture.

[0030] In some embodiments, as Figure 1 shown, there are multiple drip irrigation pipelines 12, and the multiple drip irrigation pipelines 12 are arranged around the outer side of the top opening of the cultivation cavity 111.

[0031] In this embodiment, by arranging multiple drip irrigation pipelines 12 around the top opening of the cultivation cavity 111 to simultaneously drip irrigate the top of the column 11, the rainwater for drip irrigation can fully penetrate into the entire column 11 and the nutrient core in the cultivation cavity 111, making the moisture in the nutrient core more uniform, which is beneficial to the growth and survival of plants.

[0032] Specifically, in some embodiments, the wall thickness of the cultivation cavity 111 is greater than or equal to 8 cm and less than or equal to 12 cm.

[0033] In this embodiment, by setting the wall thickness of the cultivation cavity 111 to 8 - 12 cm, the column 11 has sufficient strength to accommodate and support the nutrient core in the cultivation cavity 111. At the same time, the air permeability of the cultivation cavity 111 can meet the breathing needs of the plants in the nutrient core, which is beneficial to the growth and survival of plants.

[0034] Preferably, in a specific embodiment, the wall thickness of the cultivation cavity 111 is 10 cm.

[0035] Specifically, in some embodiments, as Figure 1 shown, the cultivation cavity 111 is a cylindrical cavity, and the diameter of the cultivation cavity 111 is greater than or equal to 10 cm and less than or equal to 20 cm.

[0036] In this embodiment, by setting the cultivation cavity 111 as a cylindrical cavity and setting the diameter of the cavity to 10 - 20 cm, the cultivation cavity 111 and the nutrient core inside it can meet the growth needs of plants, so as to reduce the plant maintenance frequency.

[0037] Specifically, for plants with a larger size and greater nutrient requirements, a cultivation cavity 111 with a diameter of 20 cm can be set; for plants with a smaller size and smaller nutrient requirements, a cultivation cavity 111 with a diameter of 10 cm can be set. In a specific embodiment, the diameter of the cultivation cavity 111 can be 15 cm.

[0038] Specifically, in some embodiments, the height of the cultivation cavity 111 is greater than or equal to 10 cm and less than or equal to 20 cm.

[0039] In this embodiment, by setting the height of the cultivation cavity 111 to 10 - 20 cm, the growth requirements of the plant roots are met, enabling the plants to grow and survive better.

[0040] Specifically, for plants with longer root lengths, a cultivation cavity 111 with a higher height can be selected, such as a cultivation cavity 111 with a height of 20 cm; for plants with shorter root lengths, a cultivation cavity 111 with a lower height can be selected, such as a cultivation cavity 111 with a height of 10 cm. In a specific embodiment, the height of the cultivation cavity 111 can be 15 cm.

[0041] It is easy to understand that the cultivation cavity 111 can run through the entire column 11, that is, the height of the cultivation cavity 111 is the same as the overall height of the column 11. Or, the cultivation cavity 111 can also be a blind hole - shaped structure formed on the column 11, that is, the overall height of the column 11 is higher than the height of the cultivation cavity 111, and the column 11 forms a bottom plate at the bottom of the cultivation cavity 111.

[0042] In some embodiments, as Figure 1 shown, the nutrient soil column 1 further includes a humidity sensor 13. The detection end of the humidity sensor 13 is inserted into the column 11, and the humidity sensor 13 is communicatively connected to the control switch of the drip irrigation pipeline 12.

[0043] In this embodiment, by setting the humidity sensor 13 with its detection end inserted into the interior of the column 11, the water content inside the column 11 is detected. The humidity sensor 13 is communicatively connected to the control switch of the drip irrigation pipeline 12, so as to switch the drip irrigation pipeline 12 according to the water content detection data of the humidity sensor 13 to achieve automatic drip irrigation of the column 11. Specifically, when the water content in the column 11 is too high, the switch of the drip irrigation pipeline 12 is closed to stop drip irrigation; when the water content in the column 11 is too low, the switch of the drip irrigation pipeline 12 is opened to drip irrigate the column 11.

[0044] Optionally, in some embodiments, the detection end of the humidity sensor 13 is located below the liquid outlet end of the drip irrigation pipeline 12.

[0045] In this embodiment, by setting the humidity sensor 13 below the liquid outlet end of the drip irrigation pipeline 12, the water flow dripped from the drip irrigation pipeline 12 leaks downward in the column 11 under the action of gravity and accumulates at the bottom of the column 11. The detection end of the humidity sensor 13 located below can better detect the water content in the column 11, so as to control the switch of the drip irrigation pipeline 12 according to the water content.

[0046] Specifically, in some embodiments, the soil particle size of the column 11 is greater than or equal to 2 mm and less than or equal to 3 mm.

[0047] In this embodiment, the soil particle size of the column 11 is set to 2-3 mm. The soil particles can be densely stacked together, enabling the column 11 to have sufficient strength to accommodate and support the internal nutrient core and plants. At the same time, it can also prevent water leakage, resulting in water loss and waste. The gaps between the particles can also allow air to penetrate into the internal nutrient core.

[0048] In a specific embodiment, as Figure 1 shown, the column 11 is a hollow cylinder, and a cylindrical cultivation cavity 111 is formed inside the cylinder. An opening communicating with the outside is provided at the top of the cultivation cavity 111. A nutrient core is provided inside the cultivation cavity 111 for cultivating plants. The branches and leaves of the plants can extend out of the cultivation cavity 111 through the opening of the cultivation cavity 111 to receive sunlight. Three drip irrigation pipelines 12 are inserted at the edge of the opening at the top of the cultivation cavity 111. The three drip irrigation pipelines 12 are evenly arranged around the opening of the cultivation cavity 111. Specifically, the projection of the connection line between two adjacent drip irrigation pipelines 12 on the plane where the opening at the top of the cultivation cavity 111 is located and the center of the opening at the top of the cultivation cavity 111 forms an angle of 120°. A humidity sensor 13 and a corresponding control device are arranged on one side of the column 11. The detection end of the humidity sensor 13 is inserted into the inside of the column 11 from the outer wall of the column 11 to detect the water content inside the column 11.

[0049] Specifically, when making the nutrient soil column 1, the soil can be screened with a wire mesh with a pore size of 2-3 mm first to remove impurities such as stones and bricks in the soil. Then, a fertilizer aqueous solution containing nitrogen, phosphorus, and potassium can be configured according to cultivation requirements, and the fertilizer aqueous solution and the soil are mixed with each other according to a set ratio to prepare wet soil, so that the weight water content of the soil is about 25%. Then, the prepared wet soil is filled into a columnar mold, and the mold is taken out after the soil moisture evaporates. The wet soil solidifies to form the column 11 with the cultivation cavity 111. The diameter and height of the cultivation cavity 111 are both 10-20 cm, and the thickness of the column 11 is about 10 cm. The cultivation cavity 111 is filled with a nutrient core prepared from a certain proportion of organic fertilizer, peat, coconut coir, vermiculite, perlite, etc.

[0050] After the column 11 and the nutrient core are made, the drip irrigation pipeline 12 can be inserted at a position near the opening of the cultivation cavity 111 at the top of the column 11, and the humidity sensor 13 can be inserted at a position near the bottom of the column 11 to monitor the water in the column 11.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
