[0002] Dioscorea alata, a typical tuber crop widely cultivated in tropical and subtropical regions, is rich in active ingredients such as starch, cellulose, diosgenin, and allantoin, possessing significant nutritional and medicinal value. In recent years, with the popularization of the concept of food and medicine sharing the same origin and the upgrading of health consumption demands, Dioscorea alata, with its antioxidant, blood sugar-lowering, and immune-regulating physiological activities, has become increasingly popular with consumers and valued by growers, leading to a steady increase in the economic benefits of the Dioscorea alata industry. As consumer demand for Dioscorea alata increases, its cultivation area is also rapidly expanding. Improving the quality and yield of Dioscorea alata through cultivation techniques can not only achieve the goal of high quality and high yield but also provide farmers with simplified and sustainable planting solutions, contributing to rural revitalization and agricultural efficiency.
[0003] Traditional cultivation of ginseng potatoes has long relied on deep soil planting, which has strict requirements for soil quality. The soil layer needs to be 40-50 cm thick and the soil must be loose to meet the needs of vertical tuber growth. Traditional cultivation methods are prone to problems such as low tuber formation rate and poor tuber shape. In addition, large-scale soil turning is required during harvesting, and improper operation can easily damage the ginseng potatoes, increase labor costs and damage soil structure.
[0004] Therefore, there is an urgent need for an integrated trough frame for shallow-grown directional cultivation of ginseng and sweet potatoes. Utility Model Content
[0005] This application aims to address at least one of the technical problems existing in the prior art or related technologies.
[0006] To this end, this application provides an integrated trough frame for shallow-grown directional cultivation of sweet potatoes, which reduces dependence on soil thickness, guides growth, and improves the integrity of tubers at harvest.
[0007] The integrated trough frame for shallow directional cultivation of sweet potato provided in this application includes a rectangular trough, a U-shaped trough, and vine guiding pipes; wherein, the U-shaped trough is set inside the rectangular trough, and the U-shaped trough is long and narrow, used to guide the directional growth of sweet potato; the vine guiding pipes are set at the top of the rectangular trough, and the vine guiding pipes are set at the top and bottom of the rectangular trough in an arc shape, and the vine guiding pipes are used for directional traction of sweet potato vines; the depth of the rectangular trough is 25-30cm.
[0008] In some embodiments, the system further includes: a plurality of limiting blocks evenly distributed along the length of the rectangular groove; and a movable baffle disposed within the rectangular groove, the movable baffle contacting the corresponding limiting block.
[0009] In some embodiments, the rectangular groove, the U-shaped groove, the vine traction tube, and the movable baffle are made of yam vine fiber and PLA composite material.
[0010] In some embodiments, the U-shaped groove has multiple through holes that are evenly distributed along the length of the U-shaped groove.
[0011] In some embodiments, the U-shaped groove is divided into multiple grooves of different lengths, with the different lengths of the grooves adapting to the position of the movable baffle.
[0012] In some embodiments, the system further includes a plurality of drainage holes disposed at the bottom of the rectangular groove.
[0013] In some embodiments, it further includes: a support frame disposed on one side of the bottom of the rectangular groove, the support frame being inclined at an angle of 15-20° with the rectangular groove and the ground.
[0014] In some embodiments, the rectangular trough is 60cm long and 12cm wide, with multiple drainage holes of 1cm in diameter arranged in two rows at the bottom of the rectangular trough, and the vine pulling tube is 1m long with both ends fixed to the top and bottom of the rectangular trough.
[0015] Compared with the prior art, the technical solution provided in this application includes at least the following technical effects:
[0016] The integrated trough frame for shallow-growing directional cultivation of sweet potato provided in this application reduces dependence on soil thickness, guides growth, and improves tuber integrity at harvest. The rectangular trough, with a depth of 25-30cm, reduces reliance on soil thickness for planting. It serves as a substrate-filling container, with sweet potato tubers planted above a U-shaped trough.

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0026] The following reference Figures 1 to 3 This application describes an integrated trough for shallow-grown directional cultivation of sweet potatoes, provided according to some embodiments.
[0027] like Figure 1 As shown, the integrated trough frame for shallow directional cultivation of sweet potato provided according to some embodiments of this application includes a rectangular trough 1, a U-shaped trough 6, and a vine guiding pipe 7; wherein, the U-shaped trough 6 is set inside the rectangular trough 1, and the U-shaped trough is long and narrow, used to guide the directional growth of sweet potato; the vine guiding pipe 7 is set at the top of the rectangular trough 1, and the vine guiding pipe 7 is arc-shaped and set at the top and bottom of the rectangular trough 1, and the vine guiding pipe 7 is used for directional traction of sweet potato vines; the depth of the rectangular trough 1 is 25-30cm.
[0028] In this embodiment, the rectangular trough 1 has a depth of 25-30cm, reducing the dependence on soil thickness for planting. The rectangular trough 1 serves as a substrate filling container, and the sweet potato tubers are planted above the U-shaped trough 6. The U-shaped trough 6 is elongated and guides the sweet potato tubers to grow in a directional manner through its U-shaped cross-section, preventing tuber branching or deformity. The vine guide tube 7 is arc-shaped and set at the top and bottom of the rectangular trough 1 to form a continuous vine climbing path. After the sweet potato vines grow, they are guided to climb onto the vine guide tube 7, so that the vine leaves are evenly distributed, avoiding mutual shading, optimizing the photosynthetic efficiency of the vines, and preventing the vines from falling over. At harvest, the U-shaped trough 6 is directly removed, avoiding large-scale soil turning and reducing tuber damage and soil structure destruction.
[0029] In some possible embodiments, such as Figure 1 , Figure 2 As shown, it also includes: multiple limiting blocks 3, evenly distributed along the length direction of the rectangular groove 1; and a movable baffle 4, which is disposed in the rectangular groove 1 and contacts the corresponding limiting block 3.
[0030] In this embodiment, multiple limiting blocks 3 are disposed on both sides of the inner wall of the rectangular groove 1 and are evenly distributed along the length of the rectangular groove 1 to provide support and positioning for the movable baffle 4, ensuring that the movable baffle 4 maintains a stable position within the rectangular groove 1. By inserting the movable baffle 4 into the limiting blocks 3 at different positions, the planting spacing of the sweet potato can be adjusted to accommodate the differences in tuber size of different varieties of sweet potato, thereby improving space utilization. The limiting blocks 3 restrict the movable baffle to prevent it from shifting due to external forces, thus maintaining the stability of the tuber growth space.
[0031] In some possible embodiments, the rectangular groove 1, the U-shaped groove 6, the vine traction tube 7, and the movable baffle 4 are made of yam vine fiber and PLA composite material.
[0032] In this embodiment, the yam vine fiber is a natural plant fiber extracted from yam vines. It has the characteristics of being renewable and biodegradable, which enhances the flexibility and tensile strength of the composite material, while providing a certain degree of biocompatibility and reducing stimulation to plant roots. The PLA material is a bio-based plastic made from renewable resources such as corn starch through fermentation. It has good biodegradability and mechanical properties, which improves the rigidity and durability of the composite material. The yam vine fiber and PLA composite material can be completely degraded in the natural environment. After degradation, the residue of the trough frame device and the yam vine are used for replacement filling, which will not cause pollution to the soil or water source, reduce the environmental pollution caused by plastic residue, and conform to the development trend of green agriculture.
[0033] In some possible embodiments, such as Figure 3 As shown, the U-shaped groove 6 has multiple through holes, which are evenly distributed along the length of the U-shaped groove 6.
[0034] In this embodiment, multiple through holes are evenly distributed along the length of the U-shaped groove 6. These through holes allow excess water to drain from the U-shaped groove 6, promote air circulation, and prevent waterlogging and root hypoxia. At the same time, the tuber roots extend outward through the through holes, expanding the nutrient absorption range and maintaining the directional growth of the tubers within the U-shaped groove 6. When planting the tubers, a mixed layer of rice husks and hay is laid in the U-shaped groove 6. After placing the sweet potato tubers in it, the soil is covered. The rice husks and hay layers have large pores and easily absorb water, which can maintain soil moisture and buffer the lateral pressure during the expansion of the sweet potato tubers, reducing the rate of skin abrasion and improving the marketability of the tubers.
[0035] In some possible embodiments, such as Figure 1As shown, the U-shaped groove 6 has multiple grooves of different lengths, and the different lengths of the grooves are adapted to the position of the movable baffle 4.
[0036] In this embodiment, by providing U-shaped grooves 6 of various lengths, the size differences of tubers of different varieties can be adapted. Combined with the protruding limiting blocks 3 set on the inner walls of both sides of the U-shaped groove 6, the movable baffle 4 is fixed by being embedded in the limiting blocks 3. Furthermore, the movable baffle 4 can be flexibly adjusted by being embedded in the limiting blocks 3 at different positions, thereby maximizing space utilization.
[0037] In some possible embodiments, such as Figure 2 As shown, it also includes: multiple drainage holes 5, which are located at the bottom of the rectangular groove 1.
[0038] In this embodiment, multiple drainage holes 5 are evenly opened at the bottom of the rectangular trough 1 and arranged along the length of the trough. Excess water is quickly discharged from the bottom drainage holes 5 by gravity. The tubers of ginseng are quite sensitive to soil moisture content during the expansion period, and the most suitable humidity range is 60%-70%. Excess water is discharged through the drainage holes 5 to prevent the soil in the trough from being too wet for a long time. It can also reduce the incidence of soft rot and root rot of ginseng tubers. At the same time, the drainage holes 5 can also serve as a channel for air circulation. After irrigation or rainfall, air enters the trough through the drainage holes 5 to replenish the oxygen needed for root respiration.
[0039] In some possible embodiments, such as Figure 1 As shown, it also includes: a support frame 2, which is set on one side of the bottom of the rectangular groove 1. The support frame 2 is inclined at an angle of 15-20° with the rectangular groove 1.
[0040] In this embodiment, the support frame 2 is set on one side of the bottom of the rectangular groove 1, so that the rectangular groove 1 is inclined at an angle of 15-20° with the ground, forming a self-drainage efficiency, which can accelerate the discharge of water from the drainage holes 5 in the groove and ensure that the root area does not accumulate water.
[0041] In some possible embodiments, such as Figure 1 As shown, the rectangular trough 1 is 60cm long and 12cm wide. Multiple drainage holes 5 with a diameter of 1cm are distributed in two rows at the bottom of the rectangular trough 1. The vine pulling pipe 7 is 1m long and is fixed at both ends to the top and bottom of the rectangular trough 1.
[0042] In this embodiment, curved vine-guiding pipes 7 are connected to both ends of the rectangular groove 1. Utilizing the phototropism of the vine tips, the vines are guided to climb along a preset path, resulting in more even leaf distribution, improved ventilation and light penetration, reduced incidence of pests and diseases, and increased photosynthetic efficiency, thereby improving the quality of the ginseng. The vines are concentrated on the guiding pipes, avoiding the entanglement problems caused by traditional scattered vines, improving pruning and harvesting efficiency, and reducing labor costs.
[0043] During the operation of this integrated trough system for shallow-growing directional cultivation of yam, the support frame 2 is located on one side of the bottom of the rectangular trough 1, making the rectangular trough 1 inclined at a 15-20° angle to the ground, forming a self-draining slope. A U-shaped trough 6 of appropriate length is selected according to the yam variety and placed inside the rectangular trough 1. The movable baffle 4 is inserted into the corresponding limiting block 3. A mixed layer of rice husks and hay is laid inside the U-shaped trough 6, and the rectangular trough 1 is filled with planting substrate. The yam tubers are planted in the U-shaped trough 6. The vine guide tubes 7 are fixed to the top and bottom of the rectangular trough 1. Utilizing the phototropism of the yam vine tips, the vines are guided to climb along the guide tubes, forming a continuous climbing path. The vine leaves are evenly distributed on the guide tubes. The rectangular trough 1 avoids mutual shading between leaves, improving light utilization. The drainage holes 5 at the bottom of the rectangular trough 1 and the through holes of the U-shaped trough 6 work together to quickly drain excess water by gravity. Air can enter the substrate through the drainage holes 5 to maintain the oxygen required for root respiration and increase soil oxygen content. At the same time, the high porosity of the rice husk and hay layer allows for slow release of water after absorption and can buffer the lateral pressure during tuber enlargement, reducing the rate of epidermal abrasion. At harvest, the tuber integrity is ensured by directly removing the U-shaped trough 6, avoiding tuber breakage or epidermal damage caused by traditional tilling. The trough frame material is made of yam vine fiber and PLA composite, which can be completely degraded in the natural environment.
