Description

Technical Field

[0001] This invention belongs to the field of modern agricultural technology and relates to a high-yield sweet potato cultivation method based on tourism agriculture. Background Technology

[0002] Sweet potatoes are annual vines belonging to the Convolvulaceae family of the order Tubiflora, and are classified as root crops. Sweet potato roots are divided into three forms: fibrous roots, tubular roots, and tuberous roots. Fibrous roots are fibrous tubular roots that absorb water and nutrients; tubular roots are deformed, fleshy roots; and tuberous roots are the fruit-like parts that store nutrients. In conventional planting methods, all three types of sweet potato roots are interconnected. However, in modern agritourism, digging sweet potatoes doesn't offer a good sightseeing experience. Therefore, current technologies for sweet potatoes as an agritourism crop require root separation techniques to spatially separate the fibrous roots and tuberous roots.

[0003] The lowest-cost method in existing technology is vine pressing, which involves first planting seedlings, and then pressing the vines into the soil after they have grown to a certain length. This allows the nodes of the vines to regrow tubers and form fruit, as disclosed in Chinese Patent No. 201910258074.8. However, this method has the following drawbacks: 1. Seedlings require a long growth period to develop vines longer than 0.5 meters before being pressed to root and bear fruit. In reality, 0.5 meters is insufficient to create a suitable space for root separation for viewing, and the distance between fibrous roots and tubers is very small; the "aerial sweet potato" can only be called an "exposed sweet potato." 2. Most importantly, because the vines are pressed into the soil after a period of growth, the nodes of the pressed vines need to regrow their root system (including tubers and fibrous roots). Compared to traditional planting methods with homologous root systems, this... The method of layering vines to encourage rooting and fruiting significantly extends the planting cycle. Typically, seedlings take 20-35 days to grow to over 0.5 meters after planting. If layering begins at this point, the sweet potato planting cycle will be extended by 20-35 days, increasing planting costs and reducing efficiency. Compressing the planting cycle will inevitably lead to a decrease in yield. 3. Sweet potato tender leaves, as a high-quality vegetable, are often overlooked in agritourism. When using the above methods, most of the tender green tips of the sweet potato vines grow from the layered vine clusters, making the areas for harvesting sweet potatoes and sweet potato tips very close together. It is impossible to harvest both at the same time (either both sweet potatoes and sweet potato tips are too high off the ground, or both are too close to the ground, while agritourism requires sweet potatoes to be high and sweet potato tips to be low). In addition, after topping and pruning, the distance between the root tubers and sweet potato tips is even closer, which is not suitable for the needs of agritourism. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a high-yield sweet potato cultivation method based on agritourism. The technical problem this invention aims to solve is how to increase the yield of sweet potatoes for both viewing and harvesting.

[0005] The objective of this invention can be achieved through the following technical solution: A high-yield sweet potato planting method based on agritourism, characterized in that the planting system of the auxiliary planting method includes a planting frame, multiple high-position planting boxes and multiple low-position planting boxes set on the planting frame, wherein the high-position planting boxes are located above the low-position planting boxes; the planting method includes the following steps: 1. Inserting seedlings into the high-position planting boxes; 2. Guiding the vines towards the low-position planting boxes, and layering the vines 15-30cm from the top into the low-position planting boxes; 3. Performing root expansion inhibition treatment in the low-position planting boxes, and after the vines in the low-position planting boxes have rooted for 20-40 days, removing the high-position planting boxes to expose the root system in the high-position planting boxes; for plants that failed to be layered, retain the soil from the corresponding high-position planting box.

[0006] Furthermore, the planting racks are sealed off, with the high-position planting boxes located inside the shed and the low-position planting boxes located outside.

[0007] Furthermore, the distance between the soil surface of the high-level planting box and the soil surface of the low-level planting box is 60-120cm.

[0008] Furthermore, in step one, observe the growth of the vines, retain 2-3 main vines, and remove weak main vines and all branch vines; all main vines are used for layering in low-position planting boxes.

[0009] Furthermore, in step two, after the sweet potato vines are layered in the low-position planting box, they are immediately topped so that the vines branch out 3-6cm from the soil.

[0010] Furthermore, the length of the pressure strip in step two is controlled between 10 and 15 cm.

[0011] Furthermore, in step three, multiple root suppression boards are inserted into the low-position planting box. The root suppression board is a mesh board with a hollow interlayer and a mesh aperture of less than 0.2 cm. The hollow interlayer of the mesh board forms a strip-shaped opening at the top. The vines are placed into the hollow interlayer in a U-shape. Subsequently, the soil is backfilled and watered multiple times in the hollow interlayer to ensure that the vines are compacted by the soil in the hollow interlayer.

[0012] Furthermore, the root suppression board also includes a pressure plate that connects multiple root suppression boards simultaneously, and the pressure plate rests against the wall of the low-position planting box opening.

[0013] Furthermore, the lower end of the root suppression plate has an insert piece.

[0014] Furthermore, the width of the hollow interlayer of the root suppression board decreases from top to bottom, and the root suppression board is inserted along the length of the low-position planting box.

[0015] Furthermore, the elevated planting box is a detachable structure, and a support plate is fixedly installed on the planting frame. The support plate is used to support the elevated planting box and the sweet potato tubers after the elevated planting box is removed.

[0016] The advantages over existing technologies are as follows: In this elevated planting box, rooting, including tuber development, begins immediately after seedling implantation, whereas traditional methods require the vines to grow to a certain length and be layered into the soil before tuber development. This not only shortens the planting cycle and increases yield but also avoids the planting risks associated with layering failure. In this solution, if layering fails, the soil in the elevated planting box can remain, allowing for normal growth. Furthermore, existing methods struggle to ensure sufficient root separation, preventing the sweet potatoes from being kept elevated for viewing and harvesting. This solution addresses this by creating a vine-like root system before layering. The rapid growth of the vines is addressed by the fact that the low-level planting boxes used for layering also have a height above the ground, which shortens the layering length required to ensure the higher position of the high-level planting boxes. The vines growing in the low-level planting boxes, which are used for sweet potato tip harvesting, also need a certain height above the ground, otherwise it will affect the harvesting experience and the independence of the plants. Thirdly, the growth of tubers needs to minimize the pressure of the soil on them to reduce the burden on tuber expansion. In this solution, the soil that restricts the expansion of the tubers is removed after the initial expansion of the tubers, i.e., the soil in the high-level planting boxes. Under moist conditions, they have a better growth environment and increase yield. Attached Figure Description

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0025] As a sweet potato planting model based on agritourism, considering the coexistence of "high-level harvesting of sweet potatoes" and "low-level harvesting of sweet potato tips," the sweet potato seedlings are planted in the high-level planting box 2, such as... Figure 2 As shown, during the growth of the seedling vines, weak main vines and branch vines on the main vines are removed, leaving two or three main vines for layering in the low-position planting box 3. This can improve the growth rate of the main vines, reaching the length of the low-position layered vines about 30 days after planting the seedlings. At this time, some root tubers in the high-position planting box 2 are already in the swelling stage. When layering, in order to provide better rooting conditions for the vines buried in the soil, layering should be done 15-30cm from the top of the vine, and the layering length can be controlled to be more than 10cm to ensure that there is more than one node for the growth of fibrous roots. Figure 3 As shown, after the layered portion has rooted, maintain the plant in both the high-position planting box 2 and the low-position planting box 3 with soil for a period of time. The duration of this time depends on the root growth and plant growth. Ensure that the root system developed by the layered portion is sufficient to nourish the root tuber in the high-position planting box 2. Then, gradually remove the high-position planting box 2. During removal, reduce the soil in the high-position planting box 2 in batches, and carefully observe the growth changes of the root tuber in the high-position planting box 2 to avoid dehydration caused by too rapid removal. After completely or partially removing the soil from the high-position planting box 2, as... Figure 4 As shown, the root tubers are moisturized by spraying, or by maintaining humidity inside the greenhouse. Since the high-position planting box 2 and the low-position planting box 3 are located inside and outside the greenhouse respectively, small holes are made on the side of the greenhouse to allow the vines to pass through without causing significant damage. After layering in the low-position planting box 3, the vines are immediately topped to encourage branching at that location for sweet potato tip harvesting. The planting process is as follows... Figure 1 As shown.

[0026] like Figure 5 and Figure 6As shown, the root suppression board 4 located in the low-level planting box 3 has a hollow core. The root suppression board 4 is a metal or plastic mesh structure with a certain degree of deformation resistance. The mesh opening is less than 0.2cm. The hollow core of the mesh board forms a strip-shaped opening at the top. The vines are placed into the hollow core in a U-shape. Multiple main vines of the same plant used for layering are pressed into one hollow core respectively. Subsequently, the hollow core is repeatedly filled with soil and watered to ensure that the vines are compacted by the soil. The root suppression board 4 also includes a pressing plate 5, which connects to multiple corresponding root suppression boards 4. The pressing plate 5 rests against the box wall at the opening of the low-level planting box 3. The function of the pressing plate 5 is to improve the cleanliness of the space above the low-level planting box 3, optimize the sweet potato harvesting experience, and suppress weed growth. There are gaps between adjacent pressing plates 5 for watering. The lower end of the root suppression board 4 has... An insert 6 is provided to facilitate the insertion and removal of the root suppression board 4 in the low-position planting box 3. Simultaneously, the width of the hollow interlayer of the root suppression board 4 decreases progressively from top to bottom, with a maximum inner width of approximately 3cm and a minimum inner width of approximately 1.5cm. The height is approximately 30cm, and it is about 15cm from the bottom of the low-position planting box 3. The root suppression board 4 is inserted along the length of the low-position planting box 3, making it easy to remove. Furthermore, due to physical limitations on root development, there are no tuberous roots in the low-position planting box 3, only fibrous roots and some rootlets. The downward-facing nature of the roots, combined with the progressively narrowing hollow interlayer, allows the roots to disperse along the length of the hollow interlayer, which is also the length of the low-position planting box 3. This maintains a certain distance between the roots and the side panels of the low-position planting box 3, increasing the soil thickness for water and nutrient absorption and reducing management difficulty.

[0027] The elevated planting box 2 is a detachable structure. A support plate 7 is fixedly installed on the planting frame 1. The support plate 7 is used to support the elevated planting box 2 and the sweet potato tubers after the elevated planting box 2 is removed. The side panel of the elevated planting box 2 near the inner side of the planting frame 1 is a detachable structure. After removing the side panel, the soil in the elevated planting box 2 can be gradually reduced in batches.

[0028] The high-position planting box 2 is about 1.5 meters off the ground, the planting rack 1 is about 2 meters high, and the low-position planting box 3 is about half a meter off the ground, ensuring that the harvesting of sweet potatoes inside the greenhouse and the harvesting of sweet potato tips outside the greenhouse are more convenient, and optimizing the experience of sightseeing and agricultural picking tourism.

[0029] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
