Description

Technical Field

[0001] This utility model relates to the field of agricultural implements, and in particular to a modular brick-based field rainwater harvesting and soil stabilization device based on sugarcane straw. Background Technology

[0002] Sugarcane is the most widely planted and highest-yielding sugar crop in southern my country. Sugarcane stalks (mainly derived from sugarcane tops, leaves, and bagasse) are the main byproducts of sugarcane planting and sugar production, typically accounting for 20%-30% of total sugarcane production, representing a huge output. Currently, sugarcane stalks are being utilized as fertilizer, feed, fuel, and materials. However, due to limitations in processing costs and technological levels, most stalks in sugarcane-growing areas are still disposed of through on-site burning. This results in poor resource utilization, resource waste, and serious environmental impact.

[0003] Ridge cultivation is one of the main farming methods in dryland agriculture in southern my country. By concentrating topsoil into ridges, a three-dimensional soil layer is created, thickening and warming the cultivated layer while simultaneously applying seeds, fertilizers, and pesticides at the top of the ridges. This forms a micro-topography of "ridge platform-ridge furrow," enabling the ridges to retain rainwater and increase soil moisture, while the furrows provide drainage and flood prevention. However, in recent years, frequent extreme weather events with concentrated torrential rains followed by droughts have led to severe waterlogging in the furrows during the rainy season, and soil from the ridge platforms erodes down the slopes and accumulates in the furrows. The subsequent drought causes the soil in the furrows to become compacted and cracked, seriously affecting the water and soil resources environment of ridge-cultivated fields and restricting crop growth. Currently, mulching is commonly used for water and soil management in ridge-cultivated fields, but the microplastic residues left after mulching can seriously affect the soil ecological environment of farmland and are detrimental to the long-term green development of farmland. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a modular brick-based ridge farming rainwater storage and soil stabilization device based on sugarcane straw, which utilizes sugarcane straw resources in ridge farming to achieve rainwater storage and drainage, sand retention and soil stabilization in ridge farmland, and slow down the rate of soil compaction and cracking in ridge furrows.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A modular brick-based field rainwater storage and soil stabilization device based on sugarcane straw, characterized in that it includes a first plastic brick module, a second plastic brick module, and a third plastic brick module formed by hot pressing sugarcane straw. The first plastic brick module, the second plastic brick module, and the third plastic brick module are stacked detachably from top to bottom. The first plastic brick module, the second plastic brick module, and the third plastic brick module are respectively provided with a first water storage chamber, a second water storage chamber, and a third water storage chamber. The first water storage chamber and the third water storage chamber are respectively connected to the top and bottom of the second water storage chamber. The circumferential sidewalls of the second plastic brick module and the third plastic brick module are respectively provided with a first drainage hole and a second drainage hole.

[0006] The beneficial effects of this utility model are as follows: The first, second, and third molded brick modules are all hot-pressed from sugarcane straw. This utilizes the high fiber and low expansion rate of sugarcane straw to reduce the amount of silt accumulated in the furrows during rainfall, thus playing a role in sand retention and soil stabilization in ridged farmland. Simultaneously, it facilitates the rapid accumulation of rainwater in the first, second, and third water storage chambers for subsequent drainage through the first and second drainage holes, preventing the accumulation of rainwater and large amounts of silt in the furrows. During droughts, it helps to shield the soil in the furrows, preventing soil compaction and cracking due to rapid evaporation. Furthermore, using sugarcane straw as a raw material allows for degradation in the field after a crop growth cycle, providing nutrients for subsequent crop growth. This utility model, through the resource utilization of sugarcane straw, achieves rainwater storage and sand retention in ridged farmland, improving the water and soil resource conditions of ridged farmland.

[0014] Furthermore, the second molded brick module includes a second brick and a plurality of second conical nails. The plurality of second conical nails are circumferentially spaced and fixedly installed at the bottom end of the second brick. The top end of the second brick is provided with a plurality of first positioning grooves circumferentially spaced. The plurality of first conical nails are fitted into the plurality of first positioning grooves one by one. The second brick is disposed below the first brick. A plurality of second water storage chambers are disposed at intervals within the second brick. The second water storage chamber is a vertical through hole with a second buffer platform circumferentially provided on the inner wall. The second buffer platform is a stepped structure.

[0015] The beneficial effects of adopting the above-mentioned further solution are: multiple second cone nails are helpful in fixing the stacked second and first plastic brick modules in the furrow during moderate rain; the first cone nails, in conjunction with the first positioning groove, are helpful in stacking and fixing the second and first plastic brick modules; the stepped structure of the second buffer platform is helpful in slowing down the speed at which rainwater flowing down from the first water storage chamber flows down the inner wall of the second water storage chamber, thereby reducing the accumulation speed of rainwater in the furrow.

[0016] Furthermore, the second brick is a rectangular block, and a plurality of the first drainage holes are spaced apart on the sidewalls of the second brick in the length and width directions. The first drainage hole is a through hole communicating with the second water storage chamber, and any two adjacent second water storage chambers are connected.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that any two adjacent second water storage chambers are connected, which is conducive to timely discharge of rainwater accumulated in the second water storage chamber when it accumulates to a height higher than the first drainage hole, thus avoiding a large amount of water accumulation in the furrow.

[0018] Furthermore, the third molded brick module includes a third brick and a plurality of third conical nails. The plurality of third conical nails are circumferentially spaced and fixedly installed at the bottom end of the third brick.

[0028] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] like Figures 1 to 10 As shown, this embodiment provides a modular brick-based field rainwater harvesting and soil stabilization device based on sugarcane straw. It is characterized by comprising a first molded brick module 1, a second molded brick module 2, and a third molded brick module 3, all formed by hot pressing sugarcane straw. These modules are detachably stacked from top to bottom. Each module contains a first water storage chamber 12, a second water storage chamber 22, and a third water storage chamber 32. The first water storage chamber 12 and the third water storage chamber 32 are respectively connected to the top and bottom of the second water storage chamber 22. The circumferential sidewalls of the second molded brick module 2 and the third molded brick module 3 are respectively provided with a first drainage hole 212 and a second drainage hole 312.

[0030] It should be noted that in this embodiment, the sugarcane stalk fibers in the first molded brick module 1, the second molded brick module 2, and the third molded brick module 3, after being formed by high-temperature hot pressing, are tightly squeezed together, which can prevent rainwater from penetrating in a short time. Therefore, after rainwater enters the first water storage chamber 12, the second water storage chamber 22, and the third water storage chamber 32, if the speed at which the rainwater seeps into the soil at the bottom of the furrow is less than the speed at which the rainwater flows into the first water storage chamber 12, the second water storage chamber 22, and the third water storage chamber 32, the rainwater that cannot seep in time will be unable to penetrate circumferentially in a short time due to the obstruction of the sugarcane stalk fibers after being formed by high-temperature hot pressing. Then, the rainwater accumulated in the second water storage chamber 22 and the third water storage chamber 32 will be discharged through the first drainage hole 212 and the second drainage hole 312, thus avoiding the long-term soaking of the sugarcane stalks after being formed by high-temperature hot pressing by rainwater. This embodiment has three modes depending on the multi-year average rainfall intensity of the area. The mode is for applications with a multi-year average rainfall intensity of light rain (i.e., 24-hour cumulative rainfall of 0.1-10 mm). When the average annual rainfall intensity is moderate (i.e., 10-25 mm in 24 hours), only the first shaped brick module 1 needs to be used in the furrow. During rainfall, the amount of soil washed away by rainwater is relatively small, and the rainwater infiltrates immediately upon entering the first water storage chamber 12 and contacting the soil at the bottom of the furrow, preventing rainwater accumulation. When the average annual rainfall intensity is moderate (i.e., 10-25 mm in 24 hours), the first shaped brick module 1 and the second shaped brick module 2 need to be stacked in the furrow. During rainfall, the amount of soil washed away by rainwater is relatively large, and when the rainwater enters the second water storage chamber 22 after passing through the first water storage chamber 12, some rainwater infiltrates the soil at the bottom of the furrow. However, the rainwater that cannot infiltrate in time accumulates in the second water storage chamber 22. When the accumulated rainwater in the second water storage chamber 22 is higher than the height of the first drainage hole 212, the rainwater will be discharged outwards from the first drainage hole 212. When the average annual rainfall intensity is heavy (i.e., 25 mm in 24 hours), the rainwater accumulates in the second water storage chamber 22. When the soil thickness is -50mm, the first plastic brick module 1, the second plastic brick module 2, and the third plastic brick module 3 need to be stacked in the furrow. During rainfall, more rainwater washes away the soil. When rainwater enters the third furrow 32 through the first water storage chamber 12 and the second water storage chamber 22, some rainwater will infiltrate into the soil at the bottom of the furrow. However, the rainwater that cannot infiltrate in time will accumulate in the second water storage chamber 22 and the third water storage chamber 32. When the rainwater accumulates to a height higher than the second drainage hole 312 in the third water storage chamber 32, the rainwater will be discharged outward from the second drainage hole 312. If the rainwater continues to accumulate to a height higher than the first drainage hole 212, the rainwater will be discharged outward from the first drainage hole 212 at the same time. In the case of moderate or heavy rain, the first drainage hole 212 and the second drainage hole 312 are connected to a flow guiding structure to guide the discharged rainwater, thereby avoiding a large amount of water accumulation in the furrow. In this embodiment, the first water storage chamber 12 and the second water storage chamber 22 are inverted frustum shapes, and the third water storage chamber 32 is a frustum shape. The inner walls of the first water storage chamber 12, the second water storage chamber 22 and the third water storage chamber 32 are connected sequentially from top to bottom. The inverted frustum and frustum shapes of the cavity structure are beneficial to increasing the amount of rainwater stored. At the same time, compared with the cylindrical cavity structure, it is beneficial to slow down the speed at which rainwater flows down the inner wall of the cavity.

[0031] The beneficial effects of this embodiment are as follows: the first, second, and third molded brick modules are all hot-pressed from sugarcane straw, which is beneficial for utilizing the high fiber and low expansion rate of sugarcane straw. During rainfall, this reduces the amount of silt accumulated in the furrows on the ridges by rainwater erosion, thus playing a role in sand retention and soil stabilization in ridged farmland. Simultaneously, it facilitates the rapid accumulation of rainwater in the first, second, and third water storage chambers, allowing for subsequent drainage through the first and second drainage holes, thereby preventing the accumulation of rainwater and large amounts of silt in the furrows. During droughts, it helps to shield the soil in the furrows, preventing soil compaction and cracking due to rapid evaporation of water. Furthermore, using sugarcane straw as a raw material allows for degradation in the field after a crop growth cycle, providing nutrients for subsequent crop growth. This embodiment, through the resource utilization of sugarcane straw, achieves rainwater storage and sand retention in ridged farmland, improving the water and soil resource conditions of ridged farmland.

[0032] Preferred, such as Figure 2 and Figure 3 As shown, the first molded brick module 1 includes: a first brick 11, a filter cover plate 14 and a plurality of first conical nails 15. The filter cover plate 14 is fixedly installed on the top of the first brick 11, and the plurality of first conical nails 15 are circumferentially spaced and fixedly installed on the bottom of the first brick 11. The plurality of first water storage chambers 12 are vertical through holes spaced apart in the first brick 11.

[0033] It should be noted that in this embodiment, the filter cover 14 cannot completely block the mud and sand outside the first water storage chamber 12. However, compared with the existing structure in the furrow that has no mud and sand blocking, this embodiment can reduce the amount of mud and sand entering the furrow with rainwater through the filter cover 14. Furthermore, since there are large debris such as crop dead leaves and large pieces of sand and gravel on the ridge, these debris cannot pass through the filter cover 14 with rainwater and can only be blocked outside the first water storage chamber 12. When these debris accumulates on the filter cover 14, it can further block the mud and sand outside the first water storage chamber 12.

[0034] The advantages of adopting the above-mentioned preferred solution are: the filter cover helps to block leaves, large pieces of sand and gravel and other debris washed down with rainwater from entering the first water storage chamber, and at the same time helps to block some of the mud and sand washed down with rainwater from entering the first water storage chamber. In addition, the accumulation of blocked leaves, large pieces of sand and gravel and other debris on the filter cover helps to further prevent mud and sand washed down with rainwater from entering the first water storage chamber; multiple first cone nails help to fix the first plastic brick module in the furrow during light rain.

[0035] Preferred, such as Figures 2 to 4 As shown, the top of the first brick 11 is provided with an embedded groove 111, which is an annular groove. The filter cover plate 14 is adapted to and fixedly installed in the embedded groove 111. The top of the filter cover plate 14 is flush with the top of the first brick 11. The filter cover plate 14 is provided with a plurality of second filter holes 141 at intervals. The second filter holes 141 are through holes.

[0036] The advantages of adopting the above-mentioned preferred solution are: the top of the filter cover is flush with the top of the first brick, which is conducive to receiving the mixture of rainwater, mud, leaves, gravel and other materials that slide down from the ridge. The second filter hole is conducive to allowing rainwater and a small amount of mud to enter the first water storage chamber, while blocking leaves, large pieces of gravel and a large amount of mud outside the first water storage chamber.

[0037] Preferred, such as Figures 2 to 6 As shown, the first brick 11 is a rectangular block. A percolation plate 13 is fixedly installed in the four first water storage chambers 12 near the top corner of the first brick 11. The percolation plate 13 is provided with a plurality of first filter holes 131 at intervals. The remaining inner walls of the first water storage chambers 12 are provided with first buffer platforms 121 in the circumferential direction. The first buffer platform 121 is a stepped structure.

[0038] It should be noted that in this embodiment, the first brick 11, the percolation plate 13, the filter cover plate 14 and the plurality of first cone nails 15 can be integrally formed by high temperature hot pressing, or the first brick 11 and the plurality of first cone nails 15 can be integrally formed by high temperature hot pressing first, and then the percolation plate 13 and the filter cover plate 14 can be integrally formed by high temperature hot pressing respectively, and finally the percolation plate 13 and the filter cover plate 14 can be assembled onto the first brick 11 respectively. Because the actual bottom of the furrow is not completely level when it is excavated and ridged, it may be uneven. Therefore, when multiple "modular brick-type ridge-growing field rainwater harvesting and soil stabilization devices" (each "modular brick-type ridge-growing field rainwater harvesting and soil stabilization device" includes a first plastic brick module 1, a second plastic brick module 2, and a third plastic brick module 3 formed by hot pressing sugarcane straw) are set side by side along the furrow, the area connecting two adjacent "modular brick-type ridge-growing field rainwater harvesting and soil stabilization devices" (i.e. the top corner of the first brick 11) may form a depression or a convex shape. Rainwater flowing down from the ridge will carry a large amount of debris such as mud, dead leaves, and gravel to the depression area. In order to increase the interception and filtration effect of the depression area, infiltration plates 13 are added at the four top corners of the first brick 11, thereby increasing the interception and filtration effect of large mud and sand particles.

[0039] The advantages of adopting the above-mentioned preferred scheme are: the infiltration plate is conducive to enhancing the interception and filtration effect of large mud and sand particles, and the first buffer platform with a stepped structure is conducive to slowing down the speed of rainwater flowing down the inner wall of the first water storage chamber, thereby reducing the accumulation speed of rainwater in the furrow.

[0040] Preferred, such as Figure 2 , Figure 3 and Figure 7 As shown, the second molded brick module 2 includes a second brick 21 and a plurality of second conical nails 23. The plurality of second conical nails 23 are circumferentially spaced and fixedly installed at the bottom end of the second brick 21. The top end of the second brick 21 is provided with a plurality of first positioning grooves 211 circumferentially spaced. The plurality of first conical nails 15 are fitted into the plurality of first positioning grooves 211 one by one. The second brick 21 is located below the first brick 11. A plurality of second water storage chambers 22 are spaced apart in the second brick 21. The second water storage chamber 22 is a vertical through hole with a second buffer platform 221 circumferentially provided on the inner wall. The second buffer platform 221 is a stepped structure.

[0041] It should be noted that in this embodiment, the multiple second water storage chambers 22 are connected to the multiple first water storage chambers 12 in a one-to-one correspondence.

[0042] The advantages of adopting the above-mentioned preferred solution are: multiple second cone nails are beneficial for fixing the stacked second and first plastic brick modules in the furrow during moderate rain; the first cone nails, in conjunction with the first positioning groove, are beneficial for stacking and fixing the second and first plastic brick modules; the stepped structure of the second buffer platform is beneficial for slowing down the speed at which rainwater flowing down from the first water storage chamber flows down the inner wall of the second water storage chamber, thereby reducing the accumulation speed of rainwater in the furrow.

[0043] Preferred, such as Figure 2 and Figure 3As shown, the second brick 21 is a rectangular block, and a plurality of first drainage holes 212 are spaced apart on the sidewalls of the second brick 21 in the length and width directions. The first drainage hole 212 is a through hole communicating with the second water storage chamber 22, and any two adjacent second water storage chambers 22 are connected.

[0044] The beneficial effect of adopting the above-mentioned preferred scheme is that any two adjacent second water storage chambers are connected, which is conducive to timely discharge of rainwater accumulated in the second water storage chamber when it accumulates to a height higher than the first drainage hole, thus avoiding a large amount of water accumulation in the furrow.

[0045] Preferred, such as Figure 2 , Figure 3 and Figure 8 As shown, the third molded brick module 3 includes a third brick 31 and a plurality of third conical nails 33. The plurality of third conical nails 33 are circumferentially spaced and fixedly installed at the bottom end of the third brick 31. The top end of the third brick 31 is provided with a plurality of second positioning grooves 311 circumferentially spaced. The plurality of second conical nails 23 are correspondingly and adapted to be inserted into the plurality of second positioning grooves 311. The third brick 31 is located below the second brick 21. The plurality of third water storage chambers 32 are spaced apart in the third brick 31. The third water storage chamber 32 is a vertical through hole with a third buffer platform 321 circumferentially provided on the inner wall. The third buffer platform 321 is a stepped structure.

[0046] It should be noted that in this embodiment, the multiple third water storage chambers 32 are connected to the multiple second water storage chambers 22 in a one-to-one correspondence.

[0047] The advantages of adopting the above-mentioned preferred solution are: multiple third cone nails are beneficial for fixing the stacked third plastic brick module, second plastic brick module and first plastic brick module in the furrow during heavy rain; the second cone nails, in conjunction with the second positioning groove, are beneficial for stacking and fixing the third plastic brick module and the second plastic brick module; the stepped third buffer platform is beneficial for slowing down the speed at which rainwater flowing down from the first water storage chamber and the second water storage chamber flows down the inner wall of the third water storage chamber, thereby reducing the accumulation speed of rainwater in the furrow.

[0048] Preferred, such as Figure 2 and Figure 3 As shown, the third brick 31 is a rectangular block, and a plurality of second drainage holes 312 are spaced apart on the sidewalls of the third brick 31 in the length and width directions. The second drainage holes 312 are through holes that communicate with the third water storage chamber 32, and any two adjacent third water storage chambers 32 are connected.

[0049] The beneficial effect of adopting the above-mentioned preferred scheme is that any two adjacent third water storage chambers are connected, which is conducive to timely discharge of rainwater accumulated in the third water storage chamber when it accumulates to a height higher than the second drainage hole, thus avoiding a large amount of water accumulation in the furrow.

[0050] Preferred, such as Figure 1 , Figure 9 and Figure 10 As shown, it also includes multiple connecting pipes 4, which are inserted into the first drainage hole 212 and the second drainage hole 312, for connecting two adjacent second plastic brick modules 2, or for connecting two adjacent second plastic brick modules 2 and two adjacent third plastic brick modules 3.

[0051] The advantages of adopting the above-mentioned preferred solution are: the connecting pipe is beneficial when the furrow is long and a single brick modular ridge planting field rainwater storage and soil stabilization device cannot cover the entire furrow, so as to connect multiple brick modular ridge planting field rainwater storage and soil stabilization devices to cover the entire furrow.

[0052] Preferably, it also includes a cap, which is detachably fitted onto the end of the connecting pipe 4 to seal the connecting pipe 4.

[0053] It should be noted that, in this embodiment, to ensure reliable drainage of the connecting pipe 4 throughout a crop growth cycle, both the connecting pipe 4 and the orifice cover can be made of plastic. At the end of a crop growth cycle and before re-plowing, the connecting pipe 4 and the orifice cover are collected for future use. The first plastic-molded brick module 1, the second plastic-molded brick module 2, and the third plastic-molded brick module 3, made from sugarcane straw, degrade in the field, providing nutrients for subsequent crop growth. If a crop growth cycle is short, the connecting pipe 4, formed by high-temperature hot pressing of sugarcane straw, can be used within this shorter cycle. If reliable drainage is maintained throughout the growth cycle and the pipe will not collapse due to rainwater soaking, then sugarcane straw can be used to make the connecting pipe 4 through high-temperature hot pressing. The hole cover made by high-temperature hot pressing of sugarcane straw can maintain reliable sealing during this short growth cycle and will not leak due to rainwater soaking. The hole cover can be made by high-temperature hot pressing of sugarcane straw. After a crop growth cycle ends and before the field is plowed again, it is no longer necessary to collect the connecting pipe 4 and the hole cover. The connecting pipe 4 and the hole cover can be degraded in the field along with the first plastic brick module 1, the second plastic brick module 2 and the third plastic brick module 3.

[0054] The beneficial effect of adopting the above preferred solution is that by sealing the connecting pipes in the first and second drainage holes that do not participate in drainage, the hole cover helps to prevent the accumulated rainwater from being discharged out of the first and second drainage holes that do not participate in drainage into the furrow.

[0055] The working process of this embodiment is described below: like Figures 1 to 10 As shown, before ridging a field, the width of the furrow is determined according to the length and width of a single "modular brick ridge field rainwater storage and soil stabilization device" so that the length or width of a single "modular brick ridge field rainwater storage and soil stabilization device" is matched with the required furrow width. Then, the rainfall data of the area where the device is used over many years is statistically analyzed, and the intensity of the average annual rainfall in the area is identified as light rain, moderate rain or heavy rain, in order to determine different combinations of the device. If the average annual rainfall intensity of the area is light rain, then only the first plastic brick module 1 is used, and multiple first plastic brick modules 1 are arranged sequentially along the length or width direction to form a strip structure that covers the furrow. Finally, the two sides of this strip structure abut against the side wall of the ridge, and the ridge is located above this strip structure. If the average annual rainfall intensity in the area is moderate, then the first plastic brick module 1 and the second plastic brick module 2 are stacked vertically. In this case, the stacked first plastic brick module 1 and the second plastic brick module 2 are used as a set of rainwater harvesting and soil stabilization devices. Multiple sets of rainwater harvesting and soil stabilization devices are arranged sequentially along the length or width direction to form a strip structure covering the furrows. The first drainage holes 212 in two adjacent second plastic brick modules 2 are connected by connecting pipes 4. The first drainage holes 212 that are not connected to other rainwater harvesting and soil stabilization devices ( The first drainage hole 212 located on both sides of this strip structure is sealed with a hole cover after the connecting pipe 4 is inserted, or directly blocked with a hole cover, so as to prevent a large amount of rainwater from leaking out from the first drainage hole 212. As for the first drainage hole 212 at both ends of this strip structure, it is connected to an external guiding structure, such as a drainage pipe, so as to guide the rainwater accumulated later to the weir or reservoir. Finally, the two sides of this strip structure abut against the side wall of the ridge, and the ridge is located above this strip structure. If the average annual rainfall intensity in the area is heavy rain, then the first plastic brick module 1, the second plastic brick module 2, and the third plastic brick module 3 are stacked sequentially from top to bottom. In this case, the stacked first plastic brick module 1, second plastic brick module 2, and third plastic brick module 3 form a rainwater harvesting and soil stabilization device. Multiple sets of rainwater harvesting and soil stabilization devices are arranged sequentially along the length or width direction to form a strip structure covering the furrows. The first drainage holes 212 in two adjacent second plastic brick modules 2 are connected by a connecting pipe 4, and the second drainage holes 312 in two adjacent third plastic brick modules 3 are connected by a connecting pipe 4. These modules are not connected to other rainwater harvesting and soil stabilization devices. The first drainage hole 212 and the second drainage hole 312 (i.e., the first drainage hole 212 and the second drainage hole 312 located on the side walls of this strip structure) are sealed with hole caps after the connecting pipe 4 is inserted, or directly blocked with hole caps, so as to prevent subsequent rainwater from leaking out in large quantities from the first drainage hole 212 and the second drainage hole 312. As for the first drainage hole 212 and the second drainage hole 312 at both ends of this strip structure, they are connected to external guiding structures, such as drainage pipes, so as to guide the subsequently accumulated rainwater to the weir or reservoir. Finally, the two sides of this strip structure abut against the side walls of the ridge, and the ridge is located above this strip structure.

[0056] It should be noted that this embodiment addresses the extreme weather of concentrated heavy rain followed by drought in southern my country. Such extreme weather events occur approximately 5-10 times within a growth cycle of ridge-grown crops (such as autumn corn, whose growth cycle is 85-95 days, typically sown in early July and harvested in early October) in southern my country. Furthermore, additional rainfall is rare within the growth cycle of ridge-grown crops in southern my country. As mentioned earlier, in the first, second, and third molded brick modules 1, 2, and 3, after high-temperature hot pressing, the sugarcane stalk fibers are tightly compressed together, preventing rainwater infiltration for a short period. Additionally, after each water-retaining chamber accumulates rainwater, it is immediately drained or allowed to seep into the soil from the bottommost water-retaining chamber. The subsequent high-temperature drought will then evaporate the rainwater from the sugarcane stalk fibers. Therefore, during the initial extreme weather events, sugarcane stalk fiber is not significantly soaked by rainwater. Instead, as the number of extreme weather events increases within a growth cycle of the ridge-grown crop, the degree of soaking of the sugarcane stalk fiber gradually increases, and the effectiveness of accumulating and draining rainwater gradually diminishes. This continues until the end of a growth cycle of the ridge-grown crop, at which point the sugarcane stalk fiber is almost completely soaked. At this point, the sugarcane stalk fiber can participate in decomposition, providing the farmland with various nutrients for the next cultivation (which may not be ridge cultivation; ridge cultivation can be carried out after the sugarcane stalk fiber has been completely decomposed).

[0057] This embodiment has the following beneficial effects: (1) Self-release fertilizer effect: The high fiber, light weight, low expansion rate and strong drying structure of sugarcane straw can withstand mechanical crushing and high humidity and high temperature field environment. It is also rich in nitrogen, phosphorus, potassium and other nutrients. In the later stage of degradation, it can form a green slow-release fertilizer layer, promote root growth and seedling growth, and realize the integration of "device-fertilizer".

[0058] (2) Low cost: The raw material of the device is sugarcane by-product, which is widely available and inexpensive. It adopts mature high-temperature hot pressing molding technology, with a short process flow, low energy consumption, and high yield. The device is maintenance-free and completely biodegradable, and its total life cycle cost is lower than that of traditional solutions.

[0059] (3) Modular assembly: The device adopts a modular design concept, the device structure is stable, and it can be arbitrarily combined into a "solid-storage-drainage" multi-functional array according to the rainfall in the field. The construction method is simple, the operation process is convenient, and the consumption of manpower and material resources is lower than that of traditional field drainage devices or measures.
