Technical Field

[0001] The utility model relates to the field of sandy land planting, in particular to a sandy land water guiding device. Background Art

[0002] The desert surface layer is composed of a dry sand layer, the thickness of which is generally below 30-40 cm. The dry sand layer lacks water and cannot meet the necessary conditions for plant seed germination and growth. However, the water condition of the wet sand layer is better and can meet the necessary conditions for plant seed germination and growth. The key to the problem is to guide the water in the wet sand layer to the dry sand layer to meet the needs of plant seed germination and growth. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sandy land water guiding device to solve the problem of guiding the water in the wet sand layer to the dry sand layer to meet the needs of plant seed germination and growth in the background.

[0004] The utility model adopts the following technical scheme:

[0005] The utility model provides a sandy land water guiding device, which includes a cylindrical water guiding pipe. A bottom support is arranged at the bottom of the water guiding pipe, and water guiding holes are arranged on the bottom support. A water guiding layer and a water retaining layer are arranged in the water guiding pipe, and the water guiding layer is located below the water retaining layer.

[0006] Further, the water guiding layer is loess, loam or clay.

[0007] Further, the water retaining layer is a mixture of sandy soil, biochar and a water retaining agent.

[0008] Further, a sealing film is arranged at the top of the water guiding pipe.

[0009] Further, the water guiding pipe, the bottom support and the sealing film are all made of degradable plastics.

[0010] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0011] The utility model utilizes the water absorption of the water guiding layer and the water retaining effect of the water retaining layer to transport the water in the wet sand layer to the water retaining layer, providing necessary conditions for seed germination and growth.

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] As Figure 1 , 2 shown, in this embodiment, a sand moisture guiding device is disclosed, which includes a cylindrical water conduit 1. A bottom support 2 is provided at the bottom of the water conduit 1, and a water guide hole 201 is provided on the bottom support 2. A water guide layer 3 and a water retention layer 4 are provided in the water conduit 1, and the water guide layer 3 is located below the water retention layer 4.

[0018] The lower wet sand layer is a key area for the growth of desert plants. Since the moisture condition of the wet sand layer is better, when the plant germinates, the main root will quickly extend to reach this stable water source supply area as soon as possible. Desert plants utilize their well-developed root systems to grow vertically or horizontally in the sandy soil to absorb water and nutrients to supply the transpiration and growth needs of the above-ground part of the plant. The water guide layer 3 can effectively conduct the water in the wet sand layer 6 upward to the water retention layer 4 through matrix suction and capillary action. The water retention layer 4 can effectively fix the water, prevent the loss of water and other evapotranspiration, and improve the soil water use efficiency of the plant.

[0019] In this embodiment, the water guide layer 3 is silty loam, loam or clay. When the water guide layer 3 is silty loam, the ratio of clay particles: silt particles: sand particles in the silty loam is approximately 10:60:30.

[0020] In this embodiment, the water retention layer 4 is a mixture of sandy soil, biochar and water retaining agent, and the ratio of sandy soil, biochar to water retaining agent is (800 - 1000):100:5. The water retention layer 4 composed of sandy soil, biochar and water retaining agent is beneficial to plant growth.

[0021] In this embodiment, a sealing film 5 is provided at the top of the water conduit 1; the water conduit 1, the bottom support 2 and the sealing film 5 are all made of degradable plastics.

[0022] The use process of the present utility model is as follows:

[0023] The sand moisture guiding device in this embodiment is prefabricated in the factory. The prefabrication process mainly includes: selecting a water guiding pipe 1 with an appropriate length according to the thickness of the dry sand layer 7, filling the lower layer of the water guiding pipe 1 with a water guiding layer 3, and filling the upper layer with a water retaining layer 4. After the water guiding layer 3 and the water retaining layer 4 are filled, compaction is carried out, and the compaction degree is close to the bulk density of loess soil, which is 1.3 - 1.5 g / cm 3 , and then sealing it with a sealing film 5. When in use, directly pass the sand moisture guiding device through the dry sand layer 7, make the bottom tray 2 contact with the wet sand layer 6, and after making a small opening in the sealing film 5, plants 8 can be planted in the water retaining layer 4.

[0024] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
