Description

Technical Field

[0001] This utility model relates to the field of water and fertilizer regulation technology, specifically to a soil moisture infiltration-promoting structure for apricot forests in the Loess Plateau region. Background Technology

[0002] Apricot (Prunus armeniaca) is an important ecological protection tree species in mountainous areas of my country. Its drought resistance, tolerance to poor soil, and excellent soil and water conservation effects make it crucial in soil and water conservation and ecological restoration projects in these areas. However, because apricot has long been used solely as an ecological protection tree, it has been largely left unmanaged and wild after afforestation. This has resulted in low fruit production and even poor overall plant growth. In the arid and barren natural conditions of the semi-arid loess hilly region, the growth of apricot faces significant challenges without proper water and fertilizer management.

[0003] In fact, wild, unmanaged apricot trees are sensitive to improvements in water and fertilizer conditions. Therefore, appropriate water and fertilizer management for wild apricot trees, and increasing the supply of water and fertilizer to a certain extent, has a significant impact on the growth of the apricot trees and the yield of the fruit.

[0004] Therefore, it is necessary to establish a soil moisture infiltration structure in apricot forests in the Loess Plateau to improve the local environment for apricot plant growth, promote plant growth, and increase fruit yield. Utility Model Content

[0006] This utility model provides a soil moisture infiltration promotion structure for apricot forests in the Loess Plateau, including a tree basin with a tree pit at the center. A tree pit is planted in the tree pit, and several infiltration pipes are provided in the tree basin and are evenly distributed around the tree pit. The infiltration pipe includes a pipe body with openings at both the upper and lower ends, and seepage holes are provided on the pipe wall of the lower section of the pipe body.

[0007] Preferably, the pipe body is provided with an upper filter screen and a lower filter screen, which divide the pipe cavity from top to bottom into a dead leaf filling section, a sand and gravel filling section and a seepage section. The dead leaf filling section is filled with a layer of dead leaves, the sand and gravel filling section is filled with a layer of sand and gravel, and the seepage section has seepage holes on the pipe wall.

[0008] Preferably, the lower filter screen is fixedly disposed within the tube body, and an annular support is provided on the inner wall of the tube body, with the upper filter screen detachably placed on the annular support.

[0009] Preferably, the seepage section is detachably fitted to the lower part of the sand and gravel filling section by means of threads, and the lower part of the seepage section can be detachably connected to another seepage section by means of threads.

[0012] The beneficial effects of this invention are as follows: This invention relates to a soil moisture infiltration structure for apricot forests in the Loess Plateau region. By excavating tree basins around the plants and burying infiltration pipes, rainwater is collected.

[0021] The pore size of the lower filter screen 34 is smaller than the particle size of the sand and gravel.

[0022] Example 2: like Figure 1 and Figures 3 to 5 As shown, the soil moisture infiltration structure of the loess apricot forest in this embodiment includes a tree basin 1, a tree pit 2 at the center of the tree basin 1, a tree planted in the tree pit 2, and several infiltration pipes 3 in the tree basin 1, which are evenly distributed around the tree pit 2. The infiltration pipe 3 includes a pipe body 31, which is open at both the upper and lower ends, and the lower part of the pipe body 31 has seepage holes 32 on the pipe wall.

[0023] The pipe body 31 is provided with an upper filter screen 33 and a lower filter screen 34. The upper filter screen 33 and the lower filter screen 34 divide the pipe cavity from top to bottom into a dead leaf filling section 35, a sand and gravel filling section 36 and a seepage section 37. The dead leaf filling section 35 is filled with a layer of dead leaves, the sand and gravel filling section 36 is filled with a layer of sand and gravel, and the seepage section 37 has seepage holes 32 on its pipe wall.

[0024] The lower filter screen 34 is fixedly installed inside the tube body 31, and an annular support 38 is provided on the inner wall of the tube body 31. The upper filter screen 33 can be detachably placed on the annular support 38.

[0025] The seepage section 37 is detachably fitted to the lower part of the sand and gravel filling section 36 by means of threads, and the lower part of the seepage section 37 can be detachably connected to another seepage section 37 by means of threads.

[0026] The lower part of the sand and gravel filling section 36 is provided with an external thread 36-1, the upper part of the seepage section 37 is provided with an internal thread 37-1, and the lower part is provided with an extended fitting external thread 37-2.

[0027] The pore size of the lower filter screen 34 is smaller than the particle size of the sand and gravel.

[0028] The working principle of this invention is as follows: In the loess region, a soil moisture infiltration structure for apricot forests involves burying infiltration pipes 3 around the apricot trees. The pipes are evenly distributed around a circle centered on the trunk and with a radius of 1 / 4 of the crown width. After burying the pipes, the ground around the pipe openings is treated for rainwater collection, such as by covering with a mulch. Simultaneously with burying the infiltration pipes 3, the tree basin 1 is prepared, creating a low-lying water collection point at the pipe openings, thus collecting rainwater from the crown into the infiltration pipes 3.

[0029] In a specific embodiment, the infiltration pipe 3 can be a PVC drainage pipe with a diameter of 11cm and a total length of about 30cm. The infiltration pipe 3 is buried at a depth of about 30cm, and can be extended by installing multiple infiltration sections 37 to meet the water supply needs of deeper soil layers. This is mainly because rainwater can only infiltrate and diffuse into the upper and lower soil layers directly at the lower end of the infiltration pipe 3. Therefore, after rain, a nearly spherical moist soil body will form at the lower end of the infiltration pipe 3. The center position of this moist soil body is closely related to the depth of the infiltration pipe 3. If the moist soil body is distributed in the main root layer of the apricot tree, it is beneficial to the growth of the apricot tree. Studies have shown that the 30cm deep infiltration pipe 3 forms a relatively moist zone in the 0-40cm soil layer, promoting the absorption of forest trees. Through the vertical change of soil moisture in soil layers with 30cm infiltration pipes 3 buried from May to October, it was found that the soil moisture in the 0-20cm and 20-40cm soil layers formed by the 30cm infiltration pipe 3 is relatively high.

[0030] This invention collects rainwater by excavating a tree basin 1 around the plant. The tree pit 2 facilitates rainwater infiltration along the sidewalls of the plant. The infiltration pipe 3 is a simple and easy-to-implement technique; it involves vertically burying a pipe with small holes in its wall into the soil. The infiltration pipe 3 guides rainwater into the deeper soil layers, promoting water absorption in these layers. During rainfall, a significant amount of rainwater directly enters the soil through the pipe, accelerating the infiltration rate and reducing surface evaporation. The infiltration pipe 3 effectively improves the soil moisture environment around the plant's rhizosphere.

[0031] In addition, as a preferred option, a layer of dead leaves is filled in the dead leaf filling section 35 of the pipe body 31. This not only filters soil sand and gravel and prevents clogging, but also provides pores inside the infiltration pipe 3, facilitating smoother rainwater infiltration. Simultaneously, the decomposition of the dead leaves allows nutrients to be transported deeper into the soil. The sand and gravel filling section 36 is filled with sand and gravel, the main function of which is to filter upper impurities and promote downward rainwater infiltration. The infiltration section 37 stores rainwater and, through its lower opening and infiltration holes, allows rainwater to seep into the deep root system of the plant, facilitating water absorption by the roots and promoting downward root growth. The upper filter screen 33 is detachably placed on the ring support 38. In use, sand and gravel are first filled into the sand and gravel filling section 36, then the upper filter screen 33 is manually inserted into the pipe body, with its edge overlapping the ring support 38. A layer of dead leaves is then filled in the dead leaf filling section 35, and the infiltration pipe 3 is then buried around the plant.
