Description

Technical Field

[0001] This utility model belongs to the field of leek cultivation technology, and specifically relates to a substrate-based leek cultivation device. Background Technology

[0002] Chives are a perennial root vegetable, rich in vitamins C, B1, B2, nicotinic acid, carotene, carbohydrates, and minerals. They are nutritious, versatile in preparation, and possess certain therapeutic and health-promoting properties. Cultivation methods primarily include seed propagation and transplanting, and direct seeding. Production methods include open field cultivation, off-season greenhouse cultivation, and hydroponics. Yellow chives, on the other hand, are grown using shading methods such as straw mats, earthenware pots, plastic buckets, and cellars. Naturally grown chives in the open field have green leaves, which turn yellow when shaded. When the roots are mounded and the leaf sheaths are buried in the topsoil at harvest, they turn white. A single chive can exhibit all three colors, and the plant combines characteristics of both regular chives and yellow chives.

[0003] For the shaded growth stage, the current method is as follows: a shaded arched greenhouse is used, with a bamboo frame constructed. Black horticultural fabric is then covered over the frame and secured with ropes. A black shade net is then added on top of the fabric to completely block light, allowing the chives to grow in a dark environment. During the shaded growth stage, ventilation and moisture dissipation are required at night by opening the black horticultural fabric at both ends of the greenhouse, and then covering it again in the morning.

[0004] Chives and yellow chives are suitable for planting in spring, summer, and autumn. First, prepare raised beds and plant the chives on them, with a row spacing of 25-35cm and a plant spacing of 5-10cm. Then, add substrate to the plants, a mixture of well-rotted organic fertilizer, bio-organic fertilizer, vermiculite, peat moss, wood ash, and castor bean leaves. Transplant the chives when they reach about 25cm in height. During the shaded growth stage, construct a shade tunnel for 4-6 days. Harvest when the yellow leaves are about 15cm long and the chives are about 45cm long, cutting the shovel about 5cm into the ground. Do not remove the shade tunnel frame after harvesting, allowing for continued use in subsequent crops. Then, remove the black horticultural ground cover and shade netting, and proceed with the next crop management, including field cultivation, weeding, and substrate re-introduction. Sometimes, it is necessary to dismantle the bamboo tunnel frame to facilitate field cultivation, weeding, and substrate re-introduction.

[0005] During the planting process, after each crop is managed and production resumes, it is necessary to reapply black horticultural ground cover and shade netting to the arched greenhouse frame. Furthermore, since the arched greenhouse frame is constructed of bamboo, with each row being 50m-100m long, and the entire frame approximately 50m-100m long, the black horticultural ground cover and shade netting on each frame are secured with multiple straps, requiring multiple points of securing and dismantling. This makes the covering and removal process cumbersome and time-consuming. When large-scale planting involves multiple rows, the time required for covering and removing the black horticultural ground cover and shade netting is even longer. To expedite the process, more manpower is needed in the field. Since chives are suitable for planting in spring, summer, and autumn, and multiple crops are planted in spring and autumn, the planting base needs to perform the covering and removal of black horticultural ground cover and shade netting multiple times. Therefore, there is an urgent need for a new device to replace the existing shading arched shed, which would reduce labor input costs in the cultivation and production of chives, shorten the operation time of covering and removing black horticultural ground cloth and shade net, and solve the cumbersome operation problem caused by the traditional binding and fixing method, ultimately improving the production efficiency and management convenience of chive (yellow chive) planting.

The specific technical solution is as follows: A substrate-based leek cultivation device, comprising Black gardening ground cover, the black gardening ground cover is arranged in an inverted U-shape, and the top of the black gardening ground cover is provided with a plurality of equally spaced perforations; Multiple sliding support rods are inserted into the through holes. Each sliding support rod has a sliding part connected to both ends. The sliding part is connected to the guide support rod. The lower end of the guide support rod is connected to the insertion rod assembly, which is inserted into the soil. Black shade netting, wherein the black shade netting is arranged in an inverted U-shape; Multiple sliding struts, each strut being in the shape of an inverted U-shape, are connected to the sliding support rod, and have grooves on them; Multiple sliding pressure rods are configured in an inverted U-shape. The sliding pressure rods press the black sunshade net tightly into the groove and slide simultaneously with the sliding support rod. A fixed plate is provided, on which a fixing nail is attached and inserted into the ground. The lower end of the sliding support rod is connected to the fixed plate and can slide on the fixed plate.

[0007] Preferably, the guide rod includes a lower horizontal part, and a first vertical part and a second vertical part are respectively connected to both sides of the lower horizontal part. The height of the first vertical part is set higher than that of the second vertical part. An upper horizontal part is connected to the first vertical part. A sliding groove is formed between the first vertical part, the lower horizontal part and the second vertical part, and the sliding part is disposed in the sliding groove. The insertion rod assembly is connected to the lower end surface of the lower horizontal portion.

[0008] Preferably, the sliding support rod includes a horizontal support rod, and the two ends of the horizontal support rod are connected to vertical support rods, so that the sliding support rod is in the shape of an inverted U-shape; The horizontal support rod has openings at both ends located inside the vertical support rod, and the upper horizontal part of the guide rod passes through the openings; the horizontal support rod and the vertical support rod have grooves on their outer sides.

[0009] Preferably, the fixing plate is provided with a limiting groove, and the lower end of the sliding support rod moves within the limiting groove.

[0010] Preferably, the insert assemblies at both ends of the guide rod are provided with end-face black gardening cloth, which is detachably connected to the insert assemblies.

[0011] Preferably, the sliding support rod includes a support rod that passes through the perforation in the black gardening fabric, and the two ends of the support rod are connected to limiting parts, the diameter of the limiting parts being larger than the diameter of the support rod; The sliding part is configured as a square sliding part, and the sliding part is connected to the limiting part.

[0012] Preferably, the fixing plate is provided with through holes; The fixing nail includes an insertion part and a positioning part connected to the upper end of the insertion part. The insertion part is inserted into the through hole and then into the soil. The positioning part is located on the upper surface of the fixing plate.

[0013] This utility model provides a substrate-based leek cultivation device. In leek cultivation, the land is first prepared into raised beds, and then the leeks are planted. Substrate is then applied into the holes, followed by transplanting. When the leeks grow to approximately [cm] in the open ground, the cultivation device of this utility model is erected. In this device, a black horticultural ground cover and a black shade net are arranged in an inverted U-shape, with the black horticultural ground cover positioned below the black shade net. A frame structure is formed by guide rods, insert rod assemblies, sliding rods, sliding support rods, and sliding pressure rods. The black horticultural ground cover is supported by the sliding rods, and the black shade net is pressed tightly against the sliding support rods by the sliding pressure rods. Because the sliding rods and sliding support rods are connected, pushing either the sliding rod or the sliding support rod allows the black horticultural ground cover and the black shade net to unfold and fold simultaneously. Compared to existing technologies, this device has the following advantages: 1. This utility model sets the black gardening ground cover and black shade net in an inverted U-shape and links them with sliding support rods and sliding struts to achieve integrated unfolding and folding of the black gardening ground cover and black shade net. During operation, simply push the sliding support rods or sliding struts to complete the unfolding, covering, and folding of the entire shading material on the ridge surface in one go, avoiding the cumbersome process of multiple binding and disassembly required by traditional methods, shortening the operation time, and thus improving production efficiency.

[0014] 2. The skeletal structure of the device does not need to be disassembled after the chives are harvested. Only the black horticultural ground cover and black shade net need to be gathered up before proceeding to the next round of open-field management. This design reduces the need for repeated disassembly of the bamboo frame, which can significantly save long-term labor costs in large-scale planting bases that require multiple ridges and multiple crops.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0021] See Figures 1-7This embodiment provides a substrate-grown leek cultivation device, including a black horticultural ground cover 100, which is U-shaped and has multiple equally spaced perforations 101 at its top. Multiple sliding support rods 1 pass through the perforations 101, with sliding portions 2 connected to both ends of each rod 1. The sliding portions 2 are connected to guide rods 3, and the lower end of each guide rod 3 is connected to an insertion rod assembly 4, which is inserted into the soil. A black shade net 200 is also U-shaped. Multiple sliding support rods 5 are U-shaped and connected to the sliding support rods 1, each with a groove 50. Multiple sliding pressure rods 6, each shaped like an inverted U-shape, press the black shade net 200 into the groove 50 and slide simultaneously with the sliding support rod 5. A fixing plate 7 is attached to a fixing nail 8, which is inserted into the ground. The lower end of each sliding support rod 5 is connected to the fixing plate 7 and can slide on it.

[0022] Two guide rods are installed, and multiple insertion rods 40 are connected to the lower ends of the two guide rods respectively. The insertion rods 40 are inserted into the ground to support the guide rods. A scale line can be drawn on the lower insertion part of each insertion rod 40 to ensure that the insertion depth of each insertion rod 40 is consistent, so that the two guide rods are at the same horizontal height.

[0023] Two fixing plates 7 are installed to ensure that the ground surface on which the fixing plates 7 are placed is relatively flat and at a relatively consistent height, so that the two fixing plates 7 are at the same horizontal level. Then, fixing nails 8 are used to further strengthen the fixing plates 7 and make them firmly fixed on the ground.

[0024] The fact that the two fixed plates 7 are at the same horizontal height and the two guide rods are at the same horizontal height can reduce the sliding resistance of the sliding support rod 5 and the sliding support rod 1.

[0025] It should be noted that in actual operation, due to the planting ground, there is a certain height difference between the two fixed plates 7. However, this height difference can be controlled to ensure smooth movement of the sliding support rod 5 and sliding strut 1, which are designed in an inverted U-shape. For example, in actual operation, the ground for placing the two fixed plates 7 is prepared during the land preparation process, and a common simple plumb bob is used to determine the levelness. The actual operation follows the "land preparation-ridge making" process of the planting base, allowing workers to quickly get started. Therefore, by preparing the ground for the fixed plates 7 during land preparation, it is ensured that the two fixed plates 7 are at the same height, and there is no serious jamming of the device due to uneven ground.

[0026] It should be noted that this device is used to cover and gather the black horticultural ground cover 100 and the black shade net 200 in the planting base. To meet the needs of planting, its precision does not need to be very high. It is sufficient to ensure smooth sliding. There is no need to increase the precision of the device and thus increase the cost. Therefore, the use of the fixing plate 7 and the insertion rod 40 can ensure the sliding of the device, improve efficiency, and reduce the cost of the device itself.

[0027] The black gardening mat 100 is shaped like an inverted U-shape. The top of the inverted U-shape black gardening mat 100 has multiple equally spaced perforations 101. A sliding support rod 1 passes through each perforation 101, supporting the black gardening mat 100 and allowing its sides to hang naturally. The lower ends of both sides of the black gardening mat 100 can be connected to sliding support rods 5, making the black gardening mat 100 more stable and preventing it from being blown around by the wind, thus achieving lateral shading.

[0028] Multiple sliding supports 1 support the black garden fabric 100 on guide supports. When it is necessary to fold up the black garden fabric 100, the sliding supports 1 are pushed in the same direction. At this time, the first sliding support 1 at the pushing end is pushed, and the first sliding support 1 at the end gradually moves closer to the second sliding support 1, and the black garden fabric 100 between the first sliding support 1 and the second sliding support 1 is folded up. Then, the first sliding support 1 and the second sliding support 1 are pushed until all the sliding supports 1 are pushed to the other end and converged, so that the black garden fabric 100 changes from the unfolded state to the folded state.

[0029] The sliding support rod 5 is connected to the sliding support rod 1, and the black shade net 200 is pressed into the groove 50 of the sliding support rod 5 by the sliding pressure rod 6. When the sliding support rod 1 is pushed to change the black garden fabric 100 from the unfolded state to the retracted state, the sliding support rod 5 moves accordingly. At this time, the black shade nets 200 between the sliding support rods 5 are close to each other, and the black shade net 200 is moved closer to the retracted state.

[0030] When the black garden fabric 100 and the black shade net 200 are changed from the retracted state to the unfolded state, push the sliding support rod 1 or the sliding strut 5 in the opposite direction again, or push the sliding support rod 1 or the sliding strut 5 at the same time.

[0031] It should be noted that leek cultivation using substrate can yield yellow leeks in spring, summer, and autumn. Therefore, the existing bamboo frame requires multiple covering and unbinding of the black horticultural ground cover 100 and black shade net 200 during multiple planting cycles. Since the black horticultural ground cover 100 and black shade net 200 are bound to the bamboo frame, in cases with long beds (50m-100m) and many beds, multiple points of disassembly and binding are required before the black horticultural ground cover 100 and black shade net 200 are bound. When covering again with the black horticultural ground cover 100 and black shade net 200, multiple points of binding are also required. Since the beds are quite long (50m-100m), the black garden tarpaulin 100 and black shade net 200 are usually cut to lengths of 30m-50m for easy covering and gathering. Therefore, multiple sections of black garden tarpaulin 100 and black shade net 200 are needed for covering and gathering. The ends of the bamboo frame are also sealed with black garden tarpaulin 100.

[0032] This device replaces the existing bamboo frame, avoiding the aforementioned problems in multi-crop planting production. By pushing, the black horticultural ground cover and black shade net can be simultaneously unfolded and retracted. Compared to existing planting methods, this improves efficiency. Furthermore, related components of the device, such as the sliding support rod 1, sliding strut 5, and sliding pressure rod 6, can be made of aluminum profiles, facilitating long-term use. For the end faces of the device, black horticultural ground cover is provided on the insertion rod assemblies 4 at both ends of the guide rod. This end face black horticultural ground cover is detachably connected to the insertion rod assembly 4. The end faces of this device are also sealed with black horticultural ground cover, which is detachably connected to the insertion rod assembly 4. Ventilation and moisture dissipation are achieved at night by opening the black horticultural ground cover at both ends, and then re-covering it in the morning.

[0033] In a specific implementation, the sliding support rod 1 includes a support rod that passes through the perforation 101 of the black gardening ground cover 100. Both ends of the support rod are connected to limiting parts, and the diameter of the limiting parts is larger than the diameter of the support rod. The sliding part 2 is a square sliding part that is connected to the limiting parts.

[0034] The square sliding part, which is more suitable for planting scenarios, is more suitable for the sliding of the black horticultural ground cover 100 and the black shade net 200. This can be achieved by the square sliding part plus manual pushing. If rollers are used, although it is more conducive to the sliding of the device, there are environmental factors such as wind in field planting. If rollers are used, the contact area between the rollers and the guide rods will be smaller, which will exacerbate the instability of the black horticultural ground cover 100.

[0035] In this device, the top of the black gardening cloth 100 is supported and slidable by a support rod, while its bottom is fixed to the sliding support rod 5, allowing it to slide while preventing the sides of the black gardening cloth 100 from being blown around by the wind. The limiting part prevents the top of the black gardening cloth 100 from sliding out from both ends of the support rod. Furthermore, the diameter of the perforation 101 matches the diameter of the support rod; the support rod only needs to pass through the perforation 101, without making the perforation 101 too large to completely cover the outer surface of the support rod with the black gardening cloth 100. The sliding support rod 1 or sliding part 2 located at both ends of the device is detachably fixed to the end of the guide support rod, thus securing both ends of the unfolded black gardening cloth 100.

[0036] See figure and Figure 4 In a specific implementation, the guide rod 3 includes a lower horizontal portion 31, with a first vertical portion 32 and a second vertical portion 33 connected to both sides of the lower horizontal portion 31, the first vertical portion 32 being higher than the second vertical portion 33, and an upper horizontal portion 34 connected to the first vertical portion 32. A sliding groove is formed between the first vertical portion 32, the lower horizontal portion 31, and the second vertical portion 33, and the sliding portion 32 is disposed within the sliding groove; wherein, the insert rod assembly 4 is connected to the lower end surface of the lower horizontal portion 31.

[0037] See Figure 5 In a specific implementation, the sliding support rod 5 includes a horizontal support rod 51, with vertical support rods 52 connected to both ends of the horizontal support rod 51, making the sliding support rod 5 in an inverted U-shape; wherein, the two ends of the horizontal support rod 51 are provided with openings 5 ​​on the inner side of the vertical support rod 52, and the upper horizontal part 31 of the guide rod passes through the openings 5; the grooves 50 are provided on the outer sides of the horizontal support rod 51 and the vertical support rod 52.

[0038] For the connection between sliding strut 5 and sliding support 1, please refer to the figure and Figure 4 When the sliding part 2 is positioned within the sliding groove of the guide rod, and the upper horizontal part 4 of the guide rod passes through the opening 5 of the horizontal support rod 51 of the sliding support rod 5, the lower end of the opening 5 of the horizontal support rod 51 contacts the sliding part 2, thus connecting the sliding support rod 5 and the sliding rod 1. It should be noted that the connection between the sliding support rod 5 and the sliding rod 1 is detachable. Connecting the sliding support rod 5 and the sliding rod 1 allows the black garden fabric 100 and the black shade net 200 to be simultaneously unfolded and retracted. In some alternative embodiments, the sliding support rod 5 and the sliding rod 1 may not be connected, and the unfolding and retraction of the black garden fabric 100 and the black shade net 200 can be performed independently.

[0039] See Figure 7 In a specific implementation, the fixing plate 7 is provided with a limiting groove 70, and the lower end of the sliding support rod 5 moves within the limiting groove 70. The fixing plate 7 is provided with a through hole; the fixing nail 8 includes an insertion part and a positioning part connected to the upper end of the insertion part. The insertion part is inserted into the through hole and then inserted into the soil, and the positioning part is located on the upper surface of the fixing plate 7.
