Description

Technical Field

[0001] This utility model relates to the field of layout tools, and in particular to a seedbed layout tool for rice planting. Background Technology

[0002] Rice cultivation is generally divided into four processes: breeding, germination, seedling raising, and seedling planting. After the rice seeds are germinated, the sprouted seedlings need to be planted in the seedbed using appropriate planting tools. Once the rice seedlings have grown to a sufficient depth in the seedbed, the qualified seedlings are transplanted. Traditionally, planting tools are usually plastic seedling trays with fixed spacing used to plant the rice seedlings in the seedbed, or the rice seedlings are planted directly in the base field based on experience.

[0003] Traditional rice seedling trays, when used for planting, have relatively fixed spacing that cannot be adjusted. This can easily compress vigorous seedlings, restricting their growth. Furthermore, planting rice seedlings directly in the paddy field based on experience can lead to root entanglement, increasing the damage rate of seedlings during transplanting.

[0004] Therefore, in response to the problem that traditional seedling arrangement tools can easily compress seedlings, restrict their growth, and cause seedling roots to become entangled, a seedling arrangement tool for rice planting can be designed. By designing the seedling trays as a modular, detachable, and adjustable structure, the above problems can be easily solved. Utility Model Content

[0005] To overcome the shortcomings of traditional rice seedling arrangement tools, such as plastic seedling trays which, due to their relatively fixed spacing, easily compress the seedlings and restrict their growth, and rice seedlings arranged directly in the paddy field based on experience which can lead to root entanglement and increased damage rate during transplanting, this utility model provides a seedling arrangement tool for rice planting.

[0006] The technical solution is as follows: a rice seedling arrangement tool, including a seedling tray, an arrangement support frame, rice seedling holders, and spacing pins; the center of the seedling tray has an arrangement pool for arranging rice seedlings, and the upper end of the arrangement pool has multiple sets of arrangement support frames for adjusting the longitudinal spacing of the rice seedlings. The interior of the arrangement support frame has multiple sets of rice seedling holders for planting rice seedlings. Both sides of the seedling tray have multiple sets of spacing holes for standard transverse spacing, and the interior of the spacing holes has spacing pins for attaching alignment lines.

[0007] Furthermore, damping grooves are provided at the edges of both the front and rear ends of the seedling tray, and multiple sets of graduated grooves for standard longitudinal spacing are provided at the top edges of both the front and rear side walls of the seedling tray.

[0008] Furthermore, a sub-connection groove is provided at the upper edge of one side of the seedling tray, and a corresponding female connection groove is provided at the lower edge of the other side of the seedling tray, with the sub-connection groove and the female connection groove matching and connecting.

[0009] Furthermore, the surface of the sub-dating groove is evenly provided with multiple sets of splicing holes, and the top of the female docking groove is provided with multiple sets of splicing buckles corresponding to the splicing holes, which match and engage with the splicing holes.

[0010] Furthermore, the support frame includes two sets of damping sliders, the lower ends of which extend into the interior of the damping groove, and the damping sliders slide along the damping sliders.

[0011] Furthermore, two sets of hanging rods are symmetrically mounted between the two sets of damping sliders, and each end of the two sets of hanging rods is provided with a connecting block that connects to the damping slider.

[0012] Furthermore, the spacing pin includes a spacing insert, the lower end of which extends into the interior of the spacing hole, the upper end of which is provided with a wire harness shaft, the lower end of which is connected to the spacing insert, and the upper end of which is provided with an anti-detachment ball.

[0013] Furthermore, both sides of the rice seedling tray are provided with arc-shaped hanging clips for hanging the hanging rod, and a planting trough is provided at the center of the upper end of the rice seedling tray. Multiple sets of ventilation holes are evenly provided at the bottom and side walls of the planting trough.

[0014] The beneficial effect is that, compared to traditional rice planting tools, which easily compress seedlings, restricting their growth and causing root entanglement, thus increasing the damage rate of rice seedlings during transplanting, this application uses a damping slider that slides within a damping groove, allowing the planting support frame to be positioned and adjusted on the seedling tray. Furthermore, the damping effect ensures that the support frame remains stably in the adjusted position without easily slipping. This facilitates flexible adjustment of the longitudinal planting spacing according to different rice varieties or seedling growth conditions, preventing excessively small spacing between seedlings and ensuring sufficient growth space for the seedlings. The graduated groove serves as a standard for the longitudinal spacing, providing operators with a precise reference when adjusting the position of the planting support frame, ensuring uniform and accurate longitudinal spacing, which is beneficial for rice cultivation. The rice seedlings grow uniformly, facilitating subsequent management and mechanized operations. The hanging poles ensure that the rice seedling trays are neatly arranged on the support frame, guaranteeing the orderly arrangement of the seedlings. The spacing blocks, inserted into the spacing holes, fix the position of the spacing pins on the seedling trays. By inserting spacing pins into different spacing holes, the lateral spacing can be accurately anchored, ensuring the uniformity of the rice seedlings' lateral arrangement. The binding spool is secured with a marker line, allowing operators to further standardize the lateral arrangement of the rice seedlings, making the arrangement more neat and accurate. Anti-loosening measures prevent the marker line from slipping off the binding spool during operation, ensuring its stable use. Independent seedling trays prevent root entanglement, significantly reducing replanting costs compared to traditional plastic seedling trays. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Rice cultivation is widely distributed around the world, from tropical Southeast Asia to subtropical southern China, and then to temperate Japan, South Korea, and some European countries. Fields of rice paddies can be seen lush and vibrant. The climate, soil, and water conditions vary significantly across different regions. Thanks to its strong ecological adaptability, rice has evolved numerous varieties to suit diverse growing environments. In hot, rainy, and sunny tropical regions, rice has a short growing cycle and can be harvested multiple times a year. In countries like Thailand and Vietnam, double-cropping or even triple-cropping rice is common, greatly improving land productivity. In temperate regions with relatively mild climates, rice has a longer growing cycle and emphasizes quality. For example, japonica rice from Northeast China is world-renowned for its plump grains and soft, glutinous texture.

[0023] Soil conditions are equally crucial for rice cultivation. Rice thrives in fertile, water-retentive soils, such as loam and clay. In some regions, soil improvement measures, such as adding organic fertilizers and deep tillage, create a favorable soil environment for rice growth. As for water resources, rice is a crop with high water requirements, and a stable and sufficient irrigation water source is a key guarantee for high rice yields. Whether in areas with abundant natural rainfall or areas that rely on artificial irrigation through water conservancy projects, effective water management directly affects the success or failure of rice cultivation.

[0024] Rice cultivation has significant economic value globally. It not only provides farmers with a major source of income but also drives the development of related industries. In many agricultural countries and regions, rice cultivation is a pillar industry of the rural economy. Farmers grow rice, harvest it, and sell it to earn income, which sustains their families and allows them to invest in the next round of agricultural production.

[0025] With the development of agricultural industrialization, the rice industry chain has continued to extend. In addition to the primary sale of rice, related industries such as rice processing and food manufacturing have flourished. After processing, rice can be made into various products such as rice, rice noodles, and rice cakes, further increasing the added value of rice. For example, in some regions, specialty rice processing products have become the pillar industry of the local area, not only meeting the needs of the domestic market but also being exported to all parts of the world, generating foreign exchange income for the country. In addition, rice cultivation has also driven the development of agricultural machinery, fertilizers, pesticides, and other agricultural asset industries, forming a huge and complex industrial ecosystem that plays an important role in promoting employment and driving economic growth.

[0026] Common rice seedling raising methods each have their own advantages and disadvantages. Moist seedling raising is a more traditional method. After water preparation, the seedbed is kept moist for sowing, which provides suitable humidity conditions for seed germination. However, care must be taken to prevent waterlogging in the seedbed, which can lead to seed rot and seedling decay. Dry seedling raising is carried out in a dry environment. It focuses on the looseness, permeability, water retention, and fertilizer retention capacity of the soil. Through meticulous soil management and water control, strong seedlings with well-developed root systems and thick stems are cultivated. However, it requires relatively high technical skills. Soft tray seedling raising has been widely used in recent years. Using plastic soft trays to hold nutrient soil, seedlings are sown in the trays. It has significant advantages such as facilitating mechanized transplanting, saving land resources, and improving seedling raising efficiency. It can also ensure that the seedlings are of uniform size, providing strong support for subsequent large-scale planting.

[0027] The management during the seedling raising process is meticulous and crucial. Temperature management is a key aspect. Before the seedlings emerge, the temperature of the seedbed should be kept stable by covering them with plastic film, generally between 25-30℃. This prevents slow germination due to low temperatures or scorching of the seedlings due to high temperatures. After the seedlings emerge, timely ventilation is necessary to harden them off and gradually lower the seedbed temperature, enhancing their resistance and helping them adapt to changes in the external environment. Water management is equally important. Watering should be done reasonably according to the soil moisture and the seedling growth stage, keeping the seedbed moist but not waterlogged to prevent diseases caused by excessive moisture. Water shortage hinders seedling growth. In addition, fertilization management is also extremely important. During the one-leaf-one-heart stage of the seedlings and 3-5 days before transplanting, apply "weaning fertilizer" and "transplanting fertilizer" respectively, mainly nitrogen fertilizer, supplemented with appropriate amounts of phosphorus and potassium fertilizer, to promote root growth and leaf development of the seedlings, laying a good foundation for rapid greening and tillering after transplanting. At the same time, pay close attention to the occurrence of diseases and pests, and regularly inspect the seedbed. Once diseases and pests are found, take timely and targeted control measures, such as using biological pesticides or highly effective, low-toxicity, and low-residue chemical pesticides for spraying to ensure healthy seedling growth.

[0028] After selecting the nursery, deep plowing is carried out first to loosen the soil, break up the plow pan, and increase soil aeration and permeability. The depth is generally 20-30 cm. Then, fine harrowing is performed to break up the soil clods and level the soil, making the soil particles small and uniform, creating good conditions for subsequent sowing and seedbed preparation. The application of base fertilizer is extremely important, mainly using fully decomposed organic fertilizer, such as farmyard manure and compost, combined with appropriate chemical fertilizers, such as superphosphate and potassium sulfate, to provide long-lasting and comprehensive nutrients for seedling growth. After fertilization, ridges are made. The ridge width is usually set at 1.2-1.5 meters to facilitate agricultural operations and management; the ridge height is 15-20 cm to effectively improve drainage and prevent waterlogging and root rot; the furrows between the ridges are 30-40 cm wide to facilitate walking and drainage.

[0029] Example 1

[0030] like Figures 1-5 As shown, the rice seedling arrangement tool includes a seedling tray 1, an arrangement support frame 2, rice seedling holders 3, and a spacing pin 4. The center of the seedling tray 1 has an arrangement pool 101 for arranging rice seedlings. The upper end of the arrangement pool 101 is provided with multiple sets of arrangement support frames 2 for adjusting the longitudinal spacing of the rice seedlings. The interior of the arrangement support frame 2 is provided with multiple sets of rice seedling holders 3 for planting rice seedlings. Multiple sets of spacing holes 103 for standard transverse spacing are evenly opened on both sides of the seedling tray 1. The interior of the spacing holes 103 is provided with spacing pins 4 for attaching alignment lines.

[0031] Damping grooves 102 are provided at the edges of the front and rear ends of the seedling tray 1. Multiple sets of scale grooves 104 for standard longitudinal spacing are provided at the top edges of the front and rear side walls of the arrangement pool 101. By using the scale grooves 104 as the standard for longitudinal spacing, the operator can have a precise reference when adjusting the position of the arrangement support frame 2, ensuring that the longitudinal spacing is uniform and accurate, which is conducive to the uniform growth of rice seedlings.

[0032] A sub-connection groove 105 is provided at the upper edge of one side of the seedling tray 1, and a female connection groove 107 corresponding to the sub-connection groove 105 is provided at the lower edge of the other side of the seedling tray 1. The sub-connection groove 105 and the female connection groove 107 are matched and connected. By matching and connecting the sub-connection groove 105 and the female connection groove 107, it is convenient to splice multiple seedling trays 1 together.

[0033] The surface of the sub-connecting groove 105 is evenly provided with multiple sets of splicing holes 106, and the top of the female connecting groove 107 is provided with multiple sets of splicing buckles 108 corresponding to the splicing holes 106. The splicing buckles 108 match and engage with the splicing holes 106. By matching and engaging the splicing buckles 108 with the splicing holes 106, the firmness of the splicing of the seedling tray 1 is further enhanced, preventing the splicing of the seedling tray 1 from loosening or separating due to external factors during use.

[0034] The arrangement support frame 2 includes two sets of damping sliders 201. The lower ends of the two sets of damping sliders 201 extend into the interior of the damping groove 102. The damping sliders 201 slide along the damping sliders 201. By cooperating with the damping groove 102, the position of the arrangement support frame 2 on the seedling tray 1 can be adjusted. Furthermore, the damping effect ensures that the support frame can be stably stopped in the corresponding position after adjustment and will not easily slide.

[0035] Two sets of hanging rods 203 are symmetrically mounted between the two sets of damping sliders 201. Both ends of the two sets of hanging rods 203 are provided with connecting blocks 202 that are connected to the damping sliders 201. The hanging rods 203 provide suspension support for the rice seedling tray 3, which facilitates the installation and disassembly of the rice seedling tray 3.

[0036] The spacing pin 4 includes a spacing insert 401, the lower end of which extends into the spacing hole 103. The upper end of the spacing insert 401 is provided with a wire-binding shaft 402, the lower end of which is connected to the spacing insert 401. The upper end of the wire-binding shaft 402 is provided with an anti-detachment ball 403. By using the spacing insert 401 in conjunction with the spacing hole 103 and inserting the spacing pin 4 into different spacing holes 103, the lateral spacing can be accurately anchored to ensure the neatness of the lateral arrangement of rice seedlings. By attaching the marking line to the wire-binding shaft 402, the operator can use the marking line to further standardize the lateral arrangement of rice seedlings.

[0037] Both sides of the rice seedling tray 3 are provided with arc-shaped hanging clips 7 for hanging the hanging rod 203. The upper center of the rice seedling tray 3 is provided with a planting trough 6. The bottom and side walls of the planting trough 6 are evenly provided with multiple sets of ventilation holes 5. The arc-shaped hanging clips 7 make it easy to hang the rice seedling tray 3 on the hanging rod 203, and it is easy to replace or adjust the position of a single rice seedling tray 3. The ventilation holes 5 make the soil in the planting trough 6 have good air permeability and drainage.

[0038] When working, for different rice varieties, such as early-maturing and late-maturing varieties, early-maturing varieties have a short growth cycle and relatively short plants, so they are suitable for smaller planting spacing; late-maturing varieties have a long growth cycle and tall plants, so they need more growing space. For early-maturing varieties, according to their characteristics, the damping slider 201 of the support frame 2 is slid in the damping groove 102. Referring to the scale groove 104, the longitudinal spacing is set to about 12 cm. For late-maturing varieties, the longitudinal spacing is adjusted to 18-20 cm.

[0039] The planting spacing of different rice varieties in the horizontal direction is determined by using the spacing pins 4 and marking lines. The spacing pins 4 are inserted into the spacing holes 103 on both sides of each seedling tray 1, and the marking lines are tied to ensure that the different varieties of rice are planted accurately in their respective seedling trays 1, and it is also easy to distinguish the different varieties of areas.

[0040] Next, hang the rice seedling tray 3 on the hanging rod 203 of the support frame 2, add special nutrient soil suitable for the variety to the planting trough 6, such as adding the corresponding trace element fertilizer to the nutrient soil for some varieties with high requirements for trace elements, and then sow the germinated rice seeds and gently cover them with a thin layer of soil.

[0041] Its working principle is that the design of the scale groove 104 and the damping groove 102 enables the precise adjustment of the position of the arrangement support frame 2 for different rice varieties and actual terrain conditions under complex terrain and diverse planting needs, so as to achieve flexible spacing adjustment. The fixed distance hole 103, fixed distance pin 4 and marking line ensure the accuracy of the lateral planting spacing under different layout conditions, and even on the discontinuous splicing seedling tray 1, the uniformity of planting can be guaranteed.

[0042] Its beneficial effects are significant. By sliding the damping slider 201 within the damping groove 102, the position of the arrangement support frame 2 on the seedling tray 1 can be adjusted. Furthermore, the damping effect ensures that the support frame can stably stop at the corresponding position after adjustment, preventing easy slippage. This facilitates flexible adjustment of the longitudinal spacing according to different rice varieties or seedling growth conditions, avoiding excessive spacing between seedlings and ensuring sufficient growth space for the seedlings. The graduated groove 104 serves as a standard for the longitudinal spacing, providing operators with precise reference when adjusting the position of the arrangement support frame 2, ensuring uniform and accurate longitudinal spacing, which is beneficial for uniform rice seedling growth and facilitates subsequent management and mechanized operation. The hanging rod 203 allows water... The rice seedling trays 3 are neatly arranged on the arrangement support frame 2, ensuring the orderly arrangement of rice seedlings. The position of the spacing pins 4 on the seedling tray 1 can be fixed by inserting the spacing blocks 401 into the spacing holes 103. By inserting the spacing pins 4 into different spacing holes 103, the horizontal arrangement spacing can be accurately anchored, ensuring the neatness of the horizontal arrangement of rice seedlings. The binding shaft 402 is used to attach the marking line. Operators can use the marking line to further standardize the horizontal arrangement of rice seedlings, making the arrangement more neat and accurate. The anti-drop ball 403 prevents the marking line from slipping off the binding shaft 402 during operation, ensuring the stable use of the marking line. The independent seedling trays prevent root entanglement, significantly reducing the cost of replanting compared to traditional plastic seedling trays 1.

[0043] Example 2, based on Example 1, such as Figures 1-2 As shown, a sub-connection groove 105 is provided at the upper edge of one side of the seedling tray 1, and a female connection groove 107 corresponding to the sub-connection groove 105 is provided at the lower edge of the other side of the seedling tray 1. The sub-connection groove 105 and the female connection groove 107 are matched and connected. By matching and connecting the sub-connection groove 105 and the female connection groove 107, it is convenient to splice multiple seedling trays 1 together.

[0044] The surface of the sub-connecting groove 105 is evenly provided with multiple sets of splicing holes 106, and the top of the female connecting groove 107 is provided with multiple sets of splicing buckles 108 corresponding to the splicing holes 106. The splicing buckles 108 match and engage with the splicing holes 106. By matching and engaging the splicing buckles 108 with the splicing holes 106, the firmness of the splicing of the seedling tray 1 is further enhanced, preventing the splicing of the seedling tray 1 from loosening or separating due to external factors during use.

[0045] During the work, after the first seedling tray 1 has completed the above operations, the worker aligns the female docking groove 107 of the second seedling tray 1 with the female docking groove 105 of the first seedling tray 1, and slowly lowers it so that the splicing buckle 108 accurately engages in the splicing hole 106, thus achieving a tight connection between the two seedling trays 1. Following this method, the seedling trays 1 are continuously spliced ​​until the entire seedling field area is laid. When it is necessary to leave a passage in the middle of the seedling field for manual management, the splicing method of the seedling trays 1 can be flexibly adjusted. In the position where a passage needs to be left, the seedling trays 1 are not spliced, but are placed at a certain distance to form a natural passage. The seedling trays 1 on both sides of the passage are still operated according to the normal spacing adjustment and planting method.

[0046] Its working principle is that the design of the sub-connecting groove 105, the female connecting groove 107, the splicing buckle 108, and the splicing hole 106 of the seedling tray 1 allows multiple seedling trays 1 to be easily spliced ​​into a large area, meeting the needs of large-scale planting, while ensuring the stability after splicing.

[0047] Its beneficial effects are as follows: the splicing function of the seedling tray 1 makes the operation simple and quick when arranging seedlings in large-scale seedbeds, reducing labor and time costs. Moreover, during the seedling raising process, the spacing can be flexibly adjusted according to the growth status of the seedlings, further optimizing the growth environment of rice seedlings. This provides high-quality seedlings with well-developed root systems and strong stems for subsequent transplanting, reducing the damage rate during transplanting and improving the survival rate of transplanted seedlings. This lays a solid foundation for the success of the entire rice planting cycle. At the same time, the neat and orderly layout of the seedbed also facilitates later field management, such as fertilization, irrigation, and pest and disease control, which is conducive to improving the overall efficiency of agricultural production.
