Description

Technical Field

[0001] This invention relates to the field of agricultural production technology, and in particular to a device and method for preparing potted seedlings based on cuttings. Background Technology

[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] Sweet potatoes are the world's seventh largest consumer of carbohydrates. Cultivating sweet potatoes will help alleviate the contradiction between population growth and food shortages, and also has economic, energy, industrial, and medicinal value. According to FAO statistics, more than 110 countries around the world grow sweet potatoes, spanning Africa, Asia, North America, and South America.

[0004] Currently, sweet potato cultivation uses transplanting of cuttings after seedling cultivation. Most cuttings vary in shape and have non-straight roots. Furthermore, sweet potato cultivation involves various cutting methods, such as upright, inclined, boat-bottom, hook-shaped, and horizontal cuttings, significantly increasing the difficulty of mechanizing and automating sweet potato cultivation. In particular, the traditional bare-root sweet potato cutting method places stringent requirements on seedling factories and planting machinery, requiring manual placement of the cuttings, making it difficult to maintain consistent precision and speed. Additionally, in arid and semi-arid regions, bare-root cuttings require immediate irrigation after planting to prevent seedling death; therefore, the process often involves simultaneous planting and watering or watering before planting, which is not conducive to efficient operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a seedling preparation device based on cuttings, which enables batch indoor seedling cultivation and facilitates the automated planting of potato seedlings using various planting methods.

[0009] Preferably, the pushing member further includes a receiving plate, which is disposed on the guide plate. The guide plate has an installation hole in the middle for installing the seedling holder. The receiving plate is U-shaped and includes two support plates and a horizontal plate. The two support plates are respectively located on both sides of the installation hole. There is a space between the horizontal plate and the guide plate that can accommodate the seedling holder.

[0010] Preferably, the receiving plate is provided with a lead screw, and a motor is provided at the upper end of the lead screw.

[0011] Preferably, the seedling placement component includes a seedling placement tube and a fixing ring, the guide plate has a mounting hole in the middle, the fixing ring is installed at the mounting hole, and the seedling placement tube is slidably connected to the fixing ring.

[0012] Preferably, the cylinder body is cylindrical, with a diameter of not less than 5cm and a length of not less than 8cm.

[0013] Preferably, the device further includes an angle forming plate, which includes a first plate and a second plate, one end of the first plate and one end of the second plate are connected, and the angle between the first plate and the second plate is 90° to 150°.

[0014] This invention also provides a method for preparing potted seedlings using the cutting-based potted seedling preparation device described above, comprising:

[0015] S1, prepared seedlings;

[0016] S2. Preparation of potting material;

[0017] S3. Pot making: Press the pot cylinder into the pot body material, so that the seedling placement component penetrates the guide plate and inserts into the pot body material to form a seedling hole. Place the seedling in the seedling hole, press down the pusher to make the punch head enter the pot cylinder, squeeze, fuse and shape the pot body material and the seedling, and push it out of the pot cylinder to form a potted seedling.

[0018] Preferably, in S1, the prepared seedlings have a diameter of 4 mm or more and a length of 20 cm or more; in S2, the seedling potting materials are prepared by mixing loose soil and water in the field or indoors, and the moisture content of the potting materials is 40% or more.

[0019] Preferably, after potting, the seedlings are placed on an angle-forming board to root and shape, and can be cultivated into upright seedlings, horizontal root seedlings, or boat-bottom root seedlings as needed.

[0036] like Figures 1-4As shown, an embodiment of the present invention proposes a seedling preparation device based on cuttings, comprising: a pot cylinder 1, a pushing component 2, and a seedling placement component 3; the pot cylinder 1 includes a cylinder body and a guide rail, the guide rail being disposed on the cylinder body, the cylinder body being used to hold a soil pot 6 for the seedling; the pushing component 2 includes a guide plate 2-3, a hollow tube 2-2, and a punching head 2-1, one end of the hollow tube 2-2 being connected to the guide plate 2-3, and the other end being connected to the punching head 2-1, the guide plate 2-3 being slidably connected to the guide rail of the pot cylinder 1, the seedling placement component 3 penetrating the guide plate 2-3 and being able to be inserted into the soil pot 6, and the punching head 2-1 being used to push the soil pot 6 out of the cylinder body.

[0037] In use, the potted seedling preparation device based on cuttings of the present invention involves pressing the pot cylinder 1 into the potting material (i.e., the soil pot 6), allowing the seedling placement component 3 to penetrate the guide plate 2-3 and insert into the potting material to form a seedling hole. The seedling is then placed in the seedling hole, and the pressing component 2 is pressed down to allow the punch head 2-1 to enter the cylinder body, compressing, fusing, and shaping the potting material and seedling, and then pushing it out of the pot cylinder 1 to form a pot containing the seedling. This enables batch indoor seedling cultivation, avoiding manual placement and supply, and standardizing operational accuracy and speed. Simultaneously, using potted seedlings allows for early root development indoors, preventing seedling death due to insufficient watering. Finally, potted seedling preparation facilitates the fully automated planting of potato seedlings 7 on film.

[0038] like Figure 1 , Figure 2 As shown, the cylinder body is cylindrical, with a diameter of not less than 5cm and a length of not less than 8cm. Correspondingly, the stamping head 2-1 of the pressing member 2 is a circular plate. Of course, it is understandable that the shape of the cylinder body can be set to other shapes as needed, and the stamping head 2-1 can be matched accordingly.

[0039] The pushing component 2 is a pot body pushing head, wherein the hollow tube 2-2 has a diameter of more than 10mm to facilitate the removal of the potato seedlings 7. The guide plate 2-3 of the pot body pushing head has guide holes at both ends that can be used in conjunction with the guide rail of the pot cylinder 1.

[0040] The guide rail is an L-shaped rod. In this embodiment, there are two L-shaped rods, which are respectively arranged on opposite sides of the cylindrical body. Each L-shaped rod includes a horizontal rod and a vertical rod. One end of the horizontal rod is connected to the vertical rod, and the other end is connected to the outer wall of the cylindrical body. A guide hole is provided on each of the left and right sides of the guide plate 2-3, and the two guide holes are fitted onto the vertical rod. Specifically, the L-shaped cylindrical guide rail can be welded to both sides of the cylindrical bowl 1 body.

[0041] like Figure 3As shown, the pressing component 2 also includes a receiving plate 2-4, which is disposed on the guide plate 2-3. The guide plate 2-3 has a mounting hole in the middle for installing the seedling placement component 3. The receiving plate 2-4 is U-shaped, including two support plates and a horizontal plate. The two support plates are respectively located on both sides of the mounting hole. There is a space between the horizontal plate and the guide plate 2-3 for inserting the seedling placement component 3. The forming pressure of the pot is obtained by stepping on the receiving plate 2-4. Of course, it is understandable that a lead screw 4 can be set on the receiving plate 2-4, and a motor 5 can be set at the upper end of the lead screw 4. The pressure plate obtains the pot forming pressure through the motor 5 lead screw.

[0042] like Figure 1 , Figure 4 As shown, the seedling placement component 3 includes a seedling placement tube 3-2 and a fixing ring 3-1. The guide plate 2-3 has an installation hole in the middle, and the fixing ring 3-1 is installed at the installation hole. The seedling placement tube 3-2 is slidably connected to the fixing ring 3-1.

[0043] The fixing ring 3-1 has a central hole and a stepped outer periphery. The lower truncated cone is smaller than the upper truncated cone. The lower truncated cone is installed in the mounting hole of the guide plate 2-3 with clearance fit, and the upper truncated cone is snapped onto the plane of the guide plate 2-3.

[0044] During operation, after placing the fixing ring 3-1 in the mounting hole of the guide plate 2-3, insert the seedling tube 3-2 from top to bottom along the center hole of the fixing ring 3-1 to create a hole in the potting material. The center hole of the fixing ring 3-1 has the same diameter as the seedling tube 3-2, and can be processed into different specifications such as 3mm, 4mm, 5mm, and 6mm depending on the diameter of the potato seedling 7. The cooperation between the fixing ring 3-1, the guide plate 2-3, and the seedling tube 3-2 facilitates the preparation of potted seedlings for different potato seedlings 7.

[0045] The potted seedling preparation device based on cuttings also includes an angle forming plate 8, such as... Figure 5 As shown, the angle forming plate 8 includes a first plate and a second plate. One end of the first plate and one end of the second plate are connected, and the angle between the first plate and the second plate is 90° to 150°, which can be selected according to planting needs.

[0046] Based on the above-mentioned potted seedling preparation device based on cuttings, the present invention also proposes a potted seedling preparation method, comprising the following steps:

[0047] S1. The seed potatoes are pulled or cut to obtain the prepared seed potatoes 7. The prepared seed potatoes 7 must be strong seedlings with a diameter of 4mm or more and a length of 20cm or more.

[0048] S2. In the field or indoors, use loose soil and water to mix and prepare seedling pot materials; the moisture content of the pot materials should be above 40%, otherwise it will not be easy to form. Organic matter and other nutrients can be added appropriately.

[0049] S3. Press the cylindrical pot 1 with guide rail into the pot material to fill the cylindrical pot 1. Then, insert the seedling tube 3-2 along the mounting hole of the guide plate 2-3 of the pot body pusher. Take out the seedling tube 3-2 to form a seedling hole in the pot material. Place the sweet potato cutting into the seedling hole formed by the seedling tube 3-2. Push the receiving plate 2-4 on the pot body pusher to realize the compression, fusion and shaping of the pot material and the sweet potato seedling 7, and push out the cylindrical pot to form a pot body with the sweet potato seedling 7.

[0050] S4. Based on the characteristics of the planting equipment and the seedling morphology required by agronomy, place the potato seedlings 7 on the seedling angle shaping plate 8 to allow them to root and take shape. They can be planted one week later. Depending on whether they are placed on the angle shaping plate 8 and the angle of the plate, upright pot seedlings, horizontal root pot seedlings, and boat-bottom root pot seedlings can be cultivated, such as... Figure 5 As shown, the resulting seedlings can be directly transplanted using a duckbill transplanter or other fully automatic seedling transplanters to achieve different planting methods in open fields or on plastic film.

[0051] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.

[0052] Finally, it should be noted that, unless otherwise specified, the embodiments of the present invention and the various features thereof can be combined with each other, all of which are within the protection scope of the present invention. Although the steps are listed in the order of 1, 2, 3…, in some cases, the steps shown or described may be performed in a different order than that shown here.
