Description

Technical Field

[0001] The invention relates to the technical field of returning straw to fields and agricultural irrigation, and in particular to a fish-scale composite pipe for farmland irrigation and a method for returning straw to fields for irrigation. Background Art

[0002] The invention patent with the authorization announcement number CN114041404B discloses a method for returning corn stalks to the field by crushing them and mixing them with soil, humidifying and extruding them into composite pipes for underground irrigation. The composite pipes buried in the ground are used for farmland irrigation. After the epidermis and roots of corn stalks are crushed, the hard stems are not tightly bound to the soil on the pipe wall, so a small gap will be generated between the stems and the soil. During the process of irrigation water entering from one end of the composite pipe and flowing to the other end, it will continuously seep out from the gap at the stems on the side wall of the composite pipe. The composite pipe forms an underground seepage pipe, and the seeped irrigation water is absorbed and diffused by the soil and enters the soil to the root layer of the plant. The problem with the above composite pipe during the irrigation process is that the crushed straw and soil will be subjected to a large extrusion pressure during the process of being extruded from the conical extrusion device, resulting in the straw stems and soil being more tightly bound, and the seepage gap formed between the two is relatively narrow. After the irrigation water enters the pipe, the speed of seepage from the gap is slow, and the irrigation efficiency is low, which needs to be improved. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a fish-scale composite pipe for farmland irrigation and a method for returning the pipe to the field for irrigation.

[0004] The technical solution of the present invention is: a fish-scale composite pipe for farmland irrigation, comprising a composite pipe body made of corn stalks, soil and water, the side wall of the composite pipe body is densely covered with fish scales along its length direction, and water seepage openings are provided between adjacent fish scales.

[0005] Preferably, the root of the fish scale body is located in the middle of the side wall of the composite tube body or close to the inner side of the side wall.

[0006] Preferably, the fish scale body covers the upper side wall of the composite tube body, and the lower part of the composite tube body is a complete tube wall structure.

[0007] A method for returning fish-scale composite pipes to farmland for irrigation, the irrigation steps are as follows: Step 1: Lay the composite pipe body in the cultivated land along the length direction of the cultivated land and bury it; Step 2: Pass irrigation water into the composite pipe body. As the irrigation water flows along the composite pipe body, it will seep out from the small gaps at the stem chips inside the side wall. At the same time, it can seep into the roots of the fish scales and flow out from the seepage openings. The composite pipe body forms a high-efficiency underground seepage pipe to evenly irrigate the cultivated land.

[0008] Preferably, the side of the composite pipe body provided with the fish scale body contacts the upper soil in the cultivated land, and the side without the fish scale body contacts the lower soil in the cultivated land.

[0009] Preferably, the composite pipe body is formed by digging a deep trench on the ground surface with a trencher, and the composite pipe body is laid in the trench for burial, or the composite pipe body is laid on the ground surface and soil is covered on the composite pipe body to form a ridge for burial.

[0010] The beneficial technical effect of the present invention is as follows: the present invention forms a fish-scale-shaped farmland irrigation composite pipe by arranging fish scale bodies on the composite pipe body, and combines the seepage gaps formed by the straw stalks inside the composite pipe. After the irrigation water enters the composite pipe, it can quickly infiltrate into the seepage openings between the fish scale bodies and quickly flow out from the seepage openings, thus compensating for the problem of slow water infiltration speed relying on the straw gaps, effectively improving the efficiency of seepage irrigation, and facilitating further market promotion and application.

[0013] Embodiment 1, see attached Figure 1-2 A fish-scale composite pipe for farmland irrigation includes a composite pipe body 11 made of corn stalks, soil and water. The side wall of the composite pipe body is densely covered with fish scale bodies 12 along its length direction. Seepage openings 13 are provided between adjacent fish scale bodies 12. After the irrigation water enters the composite pipe body 11, it can quickly penetrate into the seepage openings 13 between the fish scale bodies 12 and quickly flow out from the seepage openings 13.

[0014] The root 14 of the fish scale body is located in the middle of the side wall of the composite pipe body 11 or close to the inner side of the side wall. After the irrigation water enters the pipe body, it can quickly penetrate into the root 14 of the fish scale body and flow out from the water seepage opening 13.

[0015] The fish scale body 12 covers the upper side wall of the composite pipe body 11, and the lower part of the composite pipe body 11 is a complete pipe wall structure. This design is used to make the water seepage openings 13 between the fish scale bodies 12 cover the upper area of ​​the composite pipe body 11 to ensure the water seepage effect. At the same time, the lower pipe wall of the composite pipe body 11 ensures that it has sufficient structural strength and flexibility to avoid the pipe body from breaking during operation.

[0016] Embodiment 2, a method for returning fish-scale composite pipes to farmland for irrigation, the steps are as follows: Step 1: Lay the composite pipe body 11 into the cultivated land along the length direction of the cultivated land and bury it; use a trencher to dig a deep trench on the surface of the composite pipe body 11, lay the composite pipe body into the trench for burying, or lay the composite pipe body on the surface and cover the composite pipe body 11 with soil to form a ridge for burying.

[0017] Step 2: Pass irrigation water into the composite pipe body 11. When the irrigation water flows along the composite pipe body 11, it will seep out from the small gaps at the stem cuttings in the side wall, and at the same time, it can seep into the roots 14 of the fish scale body and flow out from the seepage openings 13. Under the combined effect of the small gaps at the stem cuttings and the seepage openings 13 formed by the fish scale body 12, the composite pipe body 11 forms a high-flow rate and high-efficiency underground seepage pipe, which realizes uniform irrigation of the cultivated land, makes up for the problem of slow seepage speed relying on the gaps between the straw, and effectively improves the efficiency of seepage irrigation.

[0018] The side of the composite pipe body 11 with the fish scale body 12 contacts the upper soil in the cultivated land, and the side without the fish scale body 12 contacts the lower soil in the cultivated land. The fish scale body 12 at the upper part of the composite pipe body 11 can reduce the pressure exerted on it by the soil, avoiding the phenomenon that the water seepage opening 13 becomes smaller due to the bending under pressure, which is beneficial to ensure that the water seepage opening 13 has a higher water seepage efficiency.
