[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the implementation manners of the present utility model are not limited thereto.

[0024] As Figures 1 - 4 shown, this embodiment provides a portable plant growth device for soil leaching and gas collection, including a column body 1, a bracket 2 installed on the outer side of the bottom of the column body 1, a substrate 3 filled at the inner bottom of the column body 1, sampling ports 4 located at different horizontal heights outside the substrate 3, a quartz sand layer 5 installed at the inner bottom end of the column body 1, and a filter screen 6 below the quartz sand layer 5. A valve 7 is provided at the middle of the bottom end of the column body 1, a liquid collection bottle 8 is provided below the valve 7, a plant 10 is planted at the top of the substrate 3, a water injection hole 11, an air inlet hole 12, and a gas collection hole 13 are respectively opened along the circumference on the outer side of the top of the column body 1, a growth rack 14 is uniformly provided at the inner top of the column body 1, a spraying assembly 15 communicated with the water injection hole 11 is provided at the inner top of the column body 1, and a top cover 9 is provided at the top of the column body 1.

[0025] Overall working principle: During use, soil layers at different depths inside the soil are collected respectively, then dried and sieved, and then injected into the interior of column 1 as the substrate 3 for plant growth, and plants 10 are planted. During the planting process of plants 10, samples of the substrate 3 at different times and different depths can be obtained through multiple sampling ports 4 at different heights. Additionally, by opening the valve 7, the substrate 3 is filtered by the quartz sand layer 5 and the filter net 6 to prevent the substrate 3 from flowing down with the leaching solution and disturbing the measured value of the leaching solution. During the planting process of plants 10, for plants 10 that need to climb, multiple growth racks 14 can be installed inside column 1 for plants 10 to climb. Moreover, when spraying water, water is injected through the water injection holes 11, and then evenly sprayed around the plants 10 through the spraying assembly 15 to ensure uniform spraying.

[0026] In this embodiment, the water injection holes 11, air inlet holes 12, and air collection holes 13 on the outer side of column 1 are located on the same horizontal plane, and two groups of water injection holes 11, air inlet holes 12, and air collection holes 13 are respectively provided on different horizontal planes at the top of column 1.

[0027] Local working principle: During the growth process of plants 10, as the height of plants 10 increases, spraying, air intake, and air collection operations can be carried out through the water injection holes 11, air inlet holes 12, and air collection holes 13 at different horizontal positions.

[0028] In this embodiment, five groups of sampling ports 4 are provided, and the sampling ports 4 are located on the same straight line and perpendicular to the horizontal plane.

[0029] Local working principle: Through multiple sampling ports 4, the substrate 3 on different levels can be sampled.

[0030] In this embodiment, the growth rack 14 includes a sleeve 16, a support rod 17, a first spring 18, and a positioning component. Support rods 17 are slidably installed at both ends of the sleeve 16. A first spring 18 is provided between the ends of the two support rods 17. The middle position of the first spring 18 is fixed inside the sleeve 16. Positioning components are provided at the ends of the support rods 17 close to the first spring 18.

[0031] Local working principle: During the installation process of the growth rack 14, the sleeve 16 is horizontally placed inside column 1, and then the positioning component is adjusted to release the positioning state of the support rod 17. Using the reset function of the first spring 18, the support rod 17 is pushed out to contact the inner wall of column 1, stabilizing the positions of the sleeve 16 and the support rod 17, and forming a horizontal support at the inner bottom of column 1 for the growth and climbing of plants 10.

[0032] In this embodiment, the positioning component includes an installation groove 20, a positioning block 21, a second spring 22, and a through hole 23. Installation grooves 20 are formed at one ends of the support rods 17 close to the first spring 18. Positioning blocks 21 are vertically and slidably arranged inside the installation grooves 20. Second springs 22 are arranged between the bottom ends of the positioning blocks 21 and the inner bottom of the installation grooves 20. Through holes 23 cooperating with the positioning blocks 21 are symmetrically formed on the outer side of the sleeve 16.

[0033] Local working principle: In the initial state, the positioning block 21 passes through the through hole 23, and the first spring 18 is in a compressed state. When the sleeve 16 is placed in a suitable position, the positioning block 21 is pressed by a finger, and the positioning block 21 is compressed into the interior of the installation groove 20, releasing the positioning state of the support rod 17. At this time, the first spring 18 automatically resets. When the support rod 17 is retracted, the support rod 17 is compressed toward the interior of the sleeve 16 until the positioning block 21 is aligned with the through hole 23, and then extends into the through hole 23 under the action of the second spring 22 to position the support rod 17.

[0034] In this embodiment, rubber blocks 19 are fixed to both ends of the support rod 17, and support blocks 24 are fixed to the inner wall of the column 1 at positions below the support rod 17.

[0035] Local working principle: The use of the rubber blocks 19 increases the friction between the support rod 17 and the inner wall of the column 1, and the support blocks 24 can support the support rod 17 to ensure the stability of the support rod 17.

[0036] In this embodiment, the spraying component 15 includes an annular pipe 25 and spray holes 26. The annular pipe 25 is horizontally fixed on the inner wall of the column 1. The interior of the annular pipe 25 communicates with the water injection holes 11, air inlet holes 12, and air collection holes 13 in the same plane. Spray holes 26 are evenly formed along the circumferential direction on the inner side of the annular pipe 25.

[0037] Local working principle: During the watering process, the air inlet holes 12 and the air collection holes 13 are blocked, and water sources enter the interior of the annular pipe 25 from the water injection holes 11, and then are sprayed out from the spray holes 26 and evenly sprayed on the plants 10.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
