Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and in particular to a drip irrigation tape. Background Technology

[0002] In the cultivation of salt-tolerant Chinese medicinal herbs, irrigation is crucial for the growth of seedlings and directly affects the survival rate of seedlings during the salt return period. Therefore, while improving water resource utilization and saving water, how to meet the irrigation needs of plants is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0003] The purpose of this invention is to provide a drip irrigation tape that can improve water resource utilization and save water while meeting the irrigation needs of plants.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A drip irrigation tape, comprising:

[0006] The tillage layer extends along the direction of crop planting, and the tillage layer includes a planting layer for planting crops;

[0007] The first drip irrigation layer includes a plurality of first pipes laid in the tillage layer, the first pipes being arranged at intervals, and the first drip irrigation layer being located in the planting layer;

[0008] The second drip irrigation layer includes multiple second pipes laid in the tillage layer, with each second pipe arranged at intervals. The second drip irrigation layer is located at the bottom of the tillage layer and is used to provide drip irrigation water after the first drip irrigation layer stops supplying water.

[0009] Optionally, in the drip irrigation tape described above, the spacing between two adjacent first pipes is the same as the sowing spacing on the planting layer.

[0010] Optionally, in the above-mentioned drip irrigation tape, the first pipe is a flexible pipe and the second pipe is a rigid pipe.

[0011] Optionally, in the above-mentioned drip irrigation tape, the number of the first pipes is the same as the number of the second pipes, and one first pipe corresponds to one second pipe.

[0012] Optionally, in the above-mentioned drip irrigation tape, the height of the tillage layer is set in the range of 25cm-35cm, the width of the planting layer is set in the range of 50cm-70cm, and the width of the bottom of the tillage layer is set in the range of 90cm-110cm.

[0013] Optionally, in the above-mentioned drip irrigation tape, the spacing between any two adjacent tillage layers in the plurality of tillage layers ranges from 35cm to 45cm.

[0014] Optionally, in the above-mentioned drip irrigation tape, the first drip irrigation layer is used to moisten and dehydrate the soil layer of 25cm-35cm in the cultivated layer, and the second drip irrigation layer is used to moisten and dehydrate the soil layer of 55cm-65cm below the surface in contact with the cultivated layer.

[0015] When using the drip irrigation tape provided by this utility model, crops are planted in the topsoil layer. The first pipe in the first drip irrigation layer of the topsoil layer irrigates the topsoil layer, making the soil moist and desalinated. After the first drip irrigation layer has completed its irrigation, the first pipe in the first drip irrigation layer is closed, and the second pipe in the second drip irrigation layer at the bottom of the topsoil layer is activated to irrigate the soil below the topsoil layer, making the lower part of the topsoil layer moist and desalinated. In this way, by alternating the water supply of the first and second drip irrigation layers, the salt that rises to the top of the topsoil layer is effectively suppressed below the surface, ensuring the normal growth of the medicinal herb roots in the desalinated topsoil layer, improving the survival rate of seedlings during the desalination period, and improving the utilization rate of freshwater, thus providing more desalination space for the roots with less water consumption.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The core of this utility model lies in providing a drip irrigation tape that improves water resource utilization and saves water while meeting the irrigation needs of plants.

[0026] like Figure 1As shown in the figure, this utility model embodiment discloses a drip irrigation tape, including a tillage layer 100, a first drip irrigation layer 200, and a second drip irrigation layer 300. The tillage layer 100 extends along the longitudinal planting direction of the crops and includes a planting layer on which the crops are planted. The first drip irrigation layer 200 includes multiple first pipes 210, each laid at intervals within the tillage layer 100, extending along the length of the tillage layer 100, and all first pipes 210 are arranged within the planting layer. The second drip irrigation layer 300 includes multiple second pipes 310 laid within the tillage layer 100, also extending along the length of the tillage layer 100, arranged at intervals, and all located at the bottom of the tillage layer 100. Water is dripped into the tillage layer 100 through the first pipes 210 and the second pipes 310. During operation, the first pipe 210 first irrigates the topsoil layer 100, moistening and desalinizing the soil. After the first drip irrigation layer 200 completes drip irrigation of the topsoil layer 100, the first pipe 210 in the first drip irrigation layer 200 is closed, and the second pipe 310 in the second drip irrigation layer 300 located at the bottom of the topsoil layer is opened to irrigate the soil below the topsoil layer 100, moistening and desalinizing the soil below the topsoil layer 100. By alternating water supply from the first drip irrigation layer 200 and the second drip irrigation layer 300, the salt rising to the top of the topsoil layer is effectively suppressed below the surface, ensuring the desalination and moisture of the planting layer. This guarantees the normal growth of the medicinal herb roots in the planting layer, improves the survival rate of seedlings during the salt rejection period, and increases the utilization rate of freshwater, providing more desalination space for the roots with less water consumption.

[0027] In addition, the spacing between two adjacent first pipes 210 is the same as the sowing spacing on the planting layer, so as to improve the ability of the first drip irrigation layer 200 to timely drip irrigate and replenish water to crops, so that water can reach the soil around the roots of crops in a timely manner, ensuring sufficient water supply, and reducing water loss and evaporation during the flow to crops.

[0028] In one specific embodiment, the first pipe 210 is a flexible pipe, while the second pipe 310 is a rigid pipe. Before digging soil to make the tillage layer 100, the second pipe 310 is laid at the bottom of the tillage layer 100. After laying, soil is piled up layer by layer. Therefore, the pipe made of rigid material has better resistance to deformation, so that water can be transported smoothly in the pipe and the drip irrigation can be implemented smoothly. The first pipe 210 laid on the tillage layer 100 is subjected to less pressure, and the need for water transportation can be met by using a flexible pipe. In addition, the flexible pipe is easy to adjust to adapt to the arrangement of crops planted on it.

[0029] like Figure 1 As shown, the number of first pipes 210 is the same as the number of second pipes 310, and one first pipe 210 and one second pipe 310 are vertically aligned to ensure that the water supply from the first pipes 210 and the second pipes 310 is concentrated below the roots of the crops, ensuring sufficient water supply and effectively suppressing salts below the surface.

[0030] In one specific embodiment, the tillage layer 100 is a flat-bottomed ridged type, that is, soil is dug from nearby forests or other places, transported to the central ground and piled up. The height of the tillage layer 100 is set in the range of 25cm-35cm, the width of the planting layer for crop planting is set in the range of 50cm-70cm, and the width of the bottom of the tillage layer 100 is set in the range of 90cm-110cm. Specifically, the height of the tillage layer 100 can be 25cm, 30cm, 33cm or 35cm, and the width of the planting layer can be 50cm or 55cm. The height of the tillage layer 100, the width of the planting layer, and the width of the bottom of the tillage layer can be 60cm, 65cm, or 70cm, and the width of the bottom of the tillage layer can be 90cm, 95cm, 100cm, or 110cm. When the height of the tillage layer 100, the width of the planting layer, and the width of the bottom of the tillage layer exceed the range, the volume of the entire tillage layer 100 is large, which increases the water consumption of the first drip irrigation layer 200 and the second drip irrigation layer 300 to moisten the soil layer of the tillage layer 100, reduces the water utilization rate, and increases water waste. When the values ​​are less than the range, the volume of the tillage layer 100 is small, which is not conducive to the growth of crops planted in the tillage layer 100.

[0031] Simultaneously, multiple tillage layers 100 are laid on the planting ground for planting crops. The spacing between any two adjacent tillage layers 100 ranges from 35cm to 45cm, specifically 35cm, 38cm, 40cm, or 45cm. If the spacing between two adjacent tillage layers 100 exceeds this range, the spacing is too large, reducing the utilization rate of the land and causing resource waste. Conversely, if the spacing between two adjacent tillage layers 100 is too small, the small gaps between the planted crops are not conducive to crop growth and reduce crop yield. It is understandable that the spacing between the tillage layers 100 is adjusted appropriately according to the crops being planted to ensure good crop growth.

[0032] In another specific embodiment, based on the plant growth patterns and the water-salt movement patterns of the Hetao saline-alkali land, staggered water supply is implemented using two layers of drip irrigation tape in spring (April-June) and autumn (September-November). Specifically, in this embodiment, the first pipe 210 of the first drip irrigation layer 200 first irrigates, keeping the topsoil layer 100 moist and desalinated from the soil layer 25-35cm below the planting layer. After 40-60 days, the drip irrigation from the first pipe 210 is shut off, and the second pipe 310 of the second drip irrigation layer 300 is activated, maintaining the soil layer 55-65cm below the surface of the topsoil layer 100 moist and desalinated. This effectively suppresses the salt rising to the top of the ridges to below 30cm below the surface. This staggered water supply method not only ensures that the roots of medicinal herbs have a 60cm desalinated layer for normal growth and improves the survival rate of seedlings during the desalination period, but also increases the utilization rate of freshwater and conserves water resources.

[0033] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0034] The above description is merely a specific 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 protection scope of the claims.
