Description

Technical Field

[0001] This utility model relates to the field of farmland water and fertilizer conservation technology, and specifically discloses a farmland water and fertilizer conservation device in a wind-water combined erosion zone. Background Technology

[0002] Arable land, as the core carrier of agricultural production, is a fundamental resource for ensuring food security and maintaining the supply of agricultural products. It plays an irreplaceable role in supporting sustainable agricultural development, stabilizing farmers' income, and maintaining ecological balance. It not only provides crops with the necessary nutrients, water, and growing space, but is also an important component of soil carbon and nitrogen pools, playing a crucial role in regulating regional water cycles, conserving soil and water, and maintaining biodiversity. Especially against the backdrop of population growth and increasing resource constraints, the water and fertilizer retention capacity of arable land directly affects agricultural production efficiency and ecosystem stability.

[0003] To improve the water retention efficiency of arable land, existing technologies widely employ the method of laying mulch film to achieve water retention by reducing soil moisture evaporation. However, in areas where wind and water erosion occur simultaneously, the stability of mulch film faces severe challenges: strong winds can easily blow the mulch film off entirely, causing the arable land to directly lose its water retention function. When the soil loses its protective cover, wind erosion of the topsoil and water erosion of nutrients are exacerbated, leading to a decline in soil fertility and severely restricting the sustainable development of arable land productivity.

[0004] Therefore, a water and fertilizer retention device for farmland in areas prone to wind and water erosion is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a water and fertilizer retention device for farmland in a combined wind and water erosion zone. It improves the stability of the mulch film, effectively prevents strong winds from blowing the mulch film off, and thus avoids the failure of its water retention function. At the same time, it reduces wind erosion on the surface soil and nutrient leaching loss caused by water erosion, prevents soil fertility decline, and ensures the continued productivity of farmland.

[0006] This utility model is implemented as follows: a water and fertilizer retention device for farmland in a combined wind and water erosion area includes a plastic film, a film pressing mechanism is provided on the upper side of the plastic film, the film pressing mechanism includes a pressing plate that is in contact with the surface of the plastic film, a filling cylinder is provided on the upper side of the pressing plate, the filling cylinder is filled with field soil, and a sealing cap is threadedly connected to the upper side of the outer wall of the filling cylinder. Below the filling cylinder is a ground-inserting rod that passes through the mulch film, and the outer wall of the ground-inserting rod drives multiple barbs; The pressure plate is provided with connecting blocks at both the left and right ends, and connecting grooves are provided at both the front and rear ends.

[0007] As a preferred embodiment of the feng shui composite erosion zone farmland water and fertilizer retention device of this utility model, the lower end of the pressure plate is provided with a threaded hole, the threaded hole is internally threaded with a threaded disc, and the ground-inserting rod is fixedly connected to the lower end of the threaded disc.

[0008] As a preferred embodiment of the feng shui composite erosion zone farmland water and fertilizer retention device of this utility model, the pressure plate, filling cylinder, sealing cover and connecting block are all made of high-density polyethylene material, and the pressure plate, filling cylinder and connecting block are integrally formed.

[0009] As a preferred embodiment of the feng shui composite erosion zone farmland water and fertilizer retention device of this utility model, the top of the inner wall of the sealed cover is fitted with a sealing gasket that abuts against the upper edge of the filling cylinder through a groove.

[0010] As a preferred embodiment of the feng shui composite erosion zone farmland water and fertilizer retention device of this utility model, the upper end of the pressure plate is provided with multiple planting holes.

[0011] As a preferred embodiment of the water and fertilizer retention device for farmland in a combined wind and water erosion zone according to this utility model, both the connecting block and the connecting groove are trapezoidal structures.

[0012] As a preferred embodiment of the feng shui composite erosion zone farmland water and fertilizer retention device of this utility model, the lower end of the ground-inserting pole has a pointed tip.

[0013] The beneficial effects of this utility model are: After the plastic film is laid on the farmland surface, planting poles are inserted into the soil. Multiple barbs on the outer wall of the poles enhance the grip with the soil, making them less likely to come out. Field soil is then filled into the filling cylinder and sealed with a lid, increasing the weight of the device and improving stability. The continuous protective surface formed by splicing multiple identical devices significantly improves the stability of the plastic film, effectively preventing strong winds from blowing it off and thus avoiding loss of its water-retention function. Simultaneously, the plastic film continuously retains water, and the continuous protective surface reduces wind erosion of the topsoil and nutrient leaching caused by water erosion, thereby preventing soil fertility decline and ensuring the continued productivity of the farmland.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figure 1-4 A water and fertilizer retention device for farmland in a wind-water composite erosion area includes a plastic film 1, a film pressing mechanism on the upper side of the plastic film 1, the film pressing mechanism includes a pressing plate 2 that is attached to the surface of the plastic film 1, a filling cylinder 3 on the upper side of the pressing plate 2, the interior of the filling cylinder 3 is filled with field soil 14, and a sealing cap 4 is threadedly connected to the upper side of the outer wall of the filling cylinder 3. Below the filling cylinder 3, there is a ground-inserting rod 6 that passes through the mulch film 1, and the outer wall of the ground-inserting rod 6 drives multiple barbs 7; The pressure plate 2 is provided with connecting blocks 11 at both the left and right ends, and connecting grooves 12 are provided at both the front and rear ends.

[0019] In this embodiment: When in use, the plastic film 1 is first laid on the surface of the cultivated land, and then the planting pole 6 is inserted into the soil through the plastic film 1. The multiple barbs 7 on the outer wall of the planting pole 6 can enhance the interlocking force with the soil and prevent the planting pole 6 from being easily pulled out, until the pressure plate 2 is attached to the upper end of the plastic film 1. Next, field soil 14 is filled into the filling cylinder 3. After filling, the sealing cap 4 is threaded onto the outer wall of the filling cylinder 3. The sealing cap 4 prevents the wind from blowing the field soil 14 out of the filling cylinder 3. The field soil 14 inside the filling cylinder 3 increases the overall weight of the film pressing mechanism and improves the stability of the mulch film 1. At the same time, multiple identical devices can be spliced ​​with the connecting slots 12 of the adjacent device's pressing plate 2 through the connecting block 11 of the pressing plate 2. After splicing, a continuous protective surface can be formed.

[0020] Based on the above description, the stability of the mulch film 1 can be significantly improved, effectively preventing strong winds from blowing it off and thus avoiding the failure of its water retention function. At the same time, the mulch film 1 continues to play a water retention role, and through the continuous protective surface, it can reduce wind erosion of the topsoil and nutrient leaching caused by water erosion, thereby preventing the decline of soil fertility and ensuring the continuous performance of arable land productivity.

[0021] As a technical optimization of this utility model, the lower end of the pressure plate 2 is provided with a threaded hole 9, and a threaded disc 10 is threadedly connected inside the threaded hole 9. The ground insertion rod 6 is fixedly connected to the lower end of the threaded disc 10.

[0022] In this embodiment, the threaded hole 9 at the lower end of the pressure plate 2 is threadedly connected to the threaded disc 10, thereby connecting and fixing the ground rod 6.

[0023] As a technical optimization of this utility model, the pressure plate 2, filling cylinder 3, sealing cover 4 and connecting block 11 are all made of high-density polyethylene material, and the pressure plate 2, filling cylinder 3 and connecting block 11 are integrally formed.

[0024] In this embodiment, the pressure plate 2, filling cylinder 3, and connecting block 11 are integrally molded from high-density polyethylene to ensure structural strength.

[0025] As a technical optimization of this utility model, a sealing gasket 5 that abuts against the upper edge of the filling cylinder 3 is installed at the top of the inner wall of the sealing cover 4 through a groove.

[0026] In this embodiment: the sealing gasket 5 on the inner wall of the closed cover 4 abuts against the upper edge of the filling cylinder 3, and fills the gap through elastic deformation to prevent water from entering the interior of the filling cylinder 3, thus avoiding the caking of the field soil 14. After use, the field soil 14 can be easily poured out.

[0027] As a technical optimization of this utility model, the upper end of the pressure plate 2 is provided with multiple planting holes 13.

[0028] In this embodiment: the planting hole 13 at the upper end of the pressure plate 2 is reserved for crop growth, so that the device can fix the mulch film 1 without affecting the planting operation. After planting is completed, soil can be covered inside the planting hole 13.

[0029] As a technical optimization of this utility model, both the connecting block 11 and the connecting groove 12 are trapezoidal structures.

[0030] In this embodiment, since both the connecting block 11 and the connecting groove 12 are trapezoidal structures, the connecting block 11 is prevented from laterally dislodging from inside the connecting groove 12.

[0031] As a technical optimization of this utility model, the lower end of the ground-inserting pole 6 has a pointed tip 8.

[0032] In this embodiment, the pointed tip 8 at the lower end of the planting pole 6 can reduce the resistance when inserting into the soil, making it easier to quickly penetrate the mulch film 1 and the surface soil.

[0033] The working principle and usage process of this utility model are as follows: When using it, first lay the plastic film 1 on the surface of the cultivated land, and then insert the planting pole 6 through the tip 8 at the bottom of the plastic film 1 into the soil. The multiple barbs 7 on the outer wall of the planting pole 6 can enhance the biting force with the soil and prevent the planting pole 6 from being easily pulled out, until the pressure plate 2 is attached to the upper end of the plastic film 1. Next, fill the filling cylinder 3 with field soil 14. After filling, thread the sealing cap 4 onto the outer wall of the filling cylinder 3, and make the sealing gasket 5 abut against the upper edge of the filling cylinder 3 to achieve a sealing effect. The sealing cap 4 prevents the wind from blowing the field soil 14 out of the filling cylinder 3; the sealing gasket 5 prevents water from entering the filling cylinder 3 and avoids the field soil 14 from clumping. After use, the field soil 14 can be easily poured out. The field soil 14 in the filling cylinder 3 increases the overall weight of the film pressing mechanism and improves the stability of the mulch film 1. At the same time, there are multiple identical devices, which can be spliced ​​with the connecting block 11 of the pressing plate 2 and the connecting groove 12 of the pressing plate 2 of the adjacent device through the connecting block 11. Since the connecting block 11 and the connecting groove 12 are both trapezoidal structures, a continuous protective surface can be formed after splicing.

[0034] Based on the above description, the stability of the mulch film 1 can be significantly improved, effectively preventing strong winds from blowing it off and thus avoiding the failure of its water retention function. At the same time, the mulch film 1 continues to play a water retention role, and through the continuous protective surface, it can reduce wind erosion of the topsoil and nutrient leaching caused by water erosion, thereby preventing the decline of soil fertility and ensuring the continuous performance of arable land productivity.
