In this embodiment, preferably, as shown in fig. 3 and 4, the irrigation holes 61 are distributed at the lower end of the irrigation pipe 6, so designed, on one hand, to facilitate reducing the insertion depth of the irrigation pipe 6, and to facilitate manual insertion of the lower end of the irrigation pipe 6 into the ground and extraction of the irrigation pipe 6, and on the other hand, to avoid water flowing out of the irrigation pipe 6 from acting on the ground surface layer 8, the lower end of the irrigation pipe 6 can be inserted into the irrigation layer 9 through the ground surface layer 8, and the root system of the crop 10 is located in the irrigation layer 9.
Preferably, the depth of the lower end of the irrigation pipe 6 from the ground is not less than 10 cm, namely the downward inserting depth of the irrigation pipe 6 is not less than 10 cm, and correspondingly, the thickness of the ground surface layer 8 is not less than 5 cm, so that the ground surface layer 8 can be effectively utilized to block sunlight and high air temperature to cause the water of the irrigation layer 9 to evaporate greatly, most of the water irrigated to the area can be used for permanently keeping the salt content in the soil in a normal range, the water resource utilization rate is high, the salt content of the soil layer where the root system is effectively reduced due to the least water consumption is realized, and the maximum treatment effect is obtained.
In this embodiment, as shown in fig. 1, the water delivery manifold 2 is connected with a water inlet pipe 4, and water is supplied into the water delivery manifold 2 through the water inlet pipe 4, so as to ensure that each irrigation pipe 6 is always full of water.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
