Description

Technical Field

[0001] The invention belongs to the field of agriculture, relates to crop seedling raising tools, and in particular to a combined grid seedling raising device and a use method thereof. Background Art

[0002] The commonly used seedling raising tools at present mainly include tray-type seedling raising trays and plug-type seedling raising trays. There is a problem with these two seedling raising tools. Due to the height limitation of the seedling raising container and the obstruction of the bottom material of the seedling raising tray, the roots of the cultivated crop seedlings will bend. At the same time, the seedling raising matrix around the root system is very small and the water storage capacity is weak. The seedling raising matrix cannot fully contact with the external soil to complete the internal and external water and gas exchange. It is very easy to dry out and needs to be monitored at any time and replenished with water in time through frequent irrigation. When irrigating, due to the small amount of seedling raising matrix and the obstruction of the bottom material of the seedling raising tray, the water in the seedling raising matrix is ​​easily in an oversaturated state, which is equivalent to the root system of the crop seedlings being in a waterlogged state. Therefore, it is necessary to carry out irrigation at the cost of reducing the amount of water applied per time to prevent waterlogging from causing root diseases, thereby further shortening the time interval between two irrigations and increasing the irrigation frequency. The above problems have increased the management intensity of crop seedling raising and increased the instability factors and risks of crop seedling raising. Summary of the invention

[0003] In view of the above problems, the present invention provides a combined grid seedling raising device, characterized in that: the seedling raising device is a grid-shaped grid seedling raising structure, which is composed of a plurality of seedling raising partitions including fins. When in use, the combined grid seedling raising device is pressed into a leveled plot, so that each grid is filled with a seedling raising matrix, and the bottom is completely in contact with the lower soil; crop seeds are sown in the seedling raising matrix in each grid to form an independent seedling raising unit with a bottom in close contact with the lower soil. When irrigation is carried out, the excess water in the seedling raising matrix flows downward into the lower soil under the action of adsorption and is stored, ensuring that the water in the seedling raising matrix is ​​in a healthy state and does not cause waterlogging, which is conducive to increasing the amount of water applied in a single irrigation, reducing the number of irrigations, and improving drought resistance; when the water in the seedling raising matrix is ​​reduced, the water stored in the lower soil will circulate upward into the seedling raising matrix, increasing the water content in the seedling raising matrix, slowing down the drought speed of the seedling raising matrix, reducing the number of irrigations, and reducing the management intensity. When transplanting after successful seedling raising, use a flat shovel tool to cut into the bottom of the combined grid seedling raising device, separate the combined grid seedling raising device together with the seedling raising matrix and the seedlings from the plot, forming an independent crop seedling pot separated by the grids of the combined grid seedling raising device, with the root system wrapped around the seedling raising matrix, which can be used for transplanting.

[0004] In order to realize the combined grid seedling raising device described in the invention, the following three technical solutions are proposed.

[0005] Technical Solution 1: The seedling partitions constituting the combined grid seedling raising device are made of plastic material. The seedling partitions are composed of fins and back plates. There are two ways to connect the fins and the back plates. One is that the fins and the back plates are integrally formed, and the other is that the fins and the back plates are connected together by snap-fitting. The root thickness of the fins is greater than the edge thickness of the fins, and the structure is wedge-shaped, so that the space surrounded by adjacent fins and the back plates presents a trapezoidal groove shape that is large outside and small inside, which is convenient for the seedling pot to be separated from the seedling partition. Fin limit grooves are set on the back of the back plate, and the range of movement of the corresponding fins is limited by the fin limit grooves to form a relatively stable grid-shaped grid structure. Multiple seedling partitions are combined together through fins and corresponding fin limit grooves to form a regularly arranged grid-shaped grid seedling raising device. The fins of the seedling partition and the bottom lower edge of the back plate are set in a blade shape to facilitate the insertion of the combined grid seedling raising device into the soil.

[0006] The advantages of technical solution one are: the seedling partitions constituting the combined grid seedling raising device are all made of plastic material, which is low in cost and easy to process, and is suitable for use in large-diameter seedling pots such as fruits and vegetables; when the fins and the back plate are connected by snap-fit ​​connection to form the seedling partitions, the seedling partitions are detachable structures, and different combinations can meet the requirements of seedlings of different specifications. After the seedling partitions are disassembled, they occupy little space and are convenient for packaging and transportation; the height of the seedling pot is determined by the height of the seedling partitions and is easy to adjust.

[0007] The plastic combined grid seedling raising device provided by Technical Solution 1 requires the fins and backboard of the seedling raising partition to reach a certain thickness to meet the strength requirements due to the need to consider factors such as structural strength. It will take up a large space and is therefore not suitable for carrying out seedling raising work in high-density, small-diameter seedling pots. Therefore, the following Technical Solution 2 is proposed.

[0008] Technical Solution 2: The seedling partitions constituting the combined grid seedling raising device are made of corrosion-resistant metal material, and the seedling partitions are composed of multiple L-shaped corrosion-resistant metal sheets connected together by welding. The L-shaped corrosion-resistant metal sheet has two folded edges, one of which is wider to form the fins of the seedling partition, and the other is narrower, which is used to be welded together with the adjacent L-shaped corrosion-resistant metal sheet. The width only needs to meet the welding requirements. The two adjacent L-shaped corrosion-resistant metal sheets form a seam at the welding point, which is used to limit the range of motion of the corresponding fins and form a relatively stable grid-shaped grid structure. At both ends of the seedling partition, a narrow strip of corrosion-resistant metal sheet is welded at the wider folded edge to form a seam for limiting the range of motion of the fins, and a corrosion-resistant metal sheet equal to the size of the fin is welded at the narrow folded edge. While generating the fins, a seam for limiting the range of motion of the fins is formed. Multiple seedling partitions are combined together through the fins and the corresponding seams to form a regularly arranged grid-shaped grid seedling raising device.

[0009] The advantages of technical solution two are: the seedling partitions that constitute the combined grid seedling device are made of corrosion-resistant metal plates as a whole, and are processed through simple sheet metal and welding processes, with low requirements for processing equipment; the wall thickness of the seedling partitions is very thin, occupying a small space, and having low resistance when inserted into the soil, which is conducive to the manufacture of seedling tools with smaller diameter and greater depth, and is suitable for high-density and deep seedling cultivation of crops such as corn and carrots that need to protect the main root system; the height of the seedling pot is determined by the height of the seedling partition and is easy to adjust.

[0010] Technical Solution 2 uses corrosion-resistant metal materials, so the material cost is relatively high. Therefore, considering the advantages and disadvantages of Technical Solution 1 and Technical Solution 2, the following Technical Solution 3 is proposed.

[0011] Technical Solution 3: The seedling partitions that constitute the combined grid seedling raising device are made of two materials: plastic and corrosion-resistant metal sheets, which are connected together by snap-on connection. The fins of the seedling raising partition are a rectangular corrosion-resistant metal sheet, and a Y-shaped snap-on structure is generated by sheet metal at one edge of the fin; the back plate of the seedling raising partition is a plastic profile, and fin fixing grooves are set on the front and back sides of the plastic profile at a specific interval, and the bottom of the fin fixing groove is a triangular cavity; the side of the fin with the Y-shaped snap-on structure is inserted into the fin fixing groove on the front of the back plate, and the fin is fixed to the back plate to form a seedling raising partition together; the fin fixing groove on the back of the back plate acts as a fin limiter at this time, which is used to limit the range of motion of the corresponding fins, forming a relatively stable grid-shaped grid structure. Multiple seedling raising partitions are combined together through fins and corresponding fin fixing grooves with a limiter function to form a regularly arranged grid-like grid seedling raising device.

[0012] The advantages of technical solution three are: the seedling partitions that constitute the combined grid seedling device are made of two materials: plastic and corrosion-resistant metal sheets, which effectively reduces costs; the seedling partitions are detachable structures, and can meet seedling requirements of different specifications through different combinations; the fin fixing grooves on both sides of the back plate of the seedling partition have the same structure, and when the fin fixing grooves on one side are damaged, the fin fixing grooves on the other side can be used to increase the service life of the back plate; the seedling partitions take up little space after being disassembled, which is convenient for packaging and transportation.

[0013] In order to achieve the application effect of the combined grid seedling raising device described in the present invention, the following method of use is proposed, which specifically includes the following steps: A. Leveling the plot: Apply sufficient basal fertilizer on the leveled plot, add the seedling matrix material and mix evenly to form a level seedling matrix layer. The thickness of the seedling matrix layer is determined by the height of the combined grid seedling device; B. Precision sowing: Combine multiple seedling raising partitions provided in the above technical solutions to form a combined square seedling raising device of a certain length, place the combined square seedling raising device on a flattened seedling raising substrate layer, place a pressure hole plate of the same size as the combined square seedling raising device and with conical protrusions with the same grid arrangement layout as the combined square seedling raising device on the combined square seedling raising device, and apply pressure to the pressure hole plate to press the combined square seedling raising device into the soil, leaving a part of it exposed to the surface, so that each square of the combined square seedling raising device is The grid is filled with seedling medium, and a part of the space is reserved on the upper part. At the same time, under the action of the conical protrusion on the pressure plate, a conical pit is generated on the upper part of the seedling medium in the grid to form a seed hole. The other combined grid seedling devices are aligned and pressed into the soil in the same way to complete the laying of the seedling devices. Crop seeds are sown in the conical seed holes in the grid, and the seedling plot is watered by spraying. Then, the combined grid seedling device is covered with fine seedling medium and scraped flat to fill the remaining space in the grid to complete precise sowing. C. Seedling management: After the emergence of crop seedlings and before transplanting, water the seedling plots in a timely manner according to needs, check the growth of seedlings in time, remove weak seedlings, adopt the method of replanting, and transplant healthy seedlings in the places where seedlings are missing to ensure that the seedlings are complete and strong; D. Cutting and removing seedlings: When the seedlings in the combined square seedling raising device reach the transplanting conditions, use a flat shovel to cut the seedling raising plot along the bottom of the combined square seedling raising device, separate a certain length of the combined square seedling raising device together with the seedling raising matrix and the seedlings inside from the plot, so that the combined square seedling raising device forms an independent seedling pot in each square; the bottom of the combined square seedling raising device containing the seedling pot is placed vertically back to back on the bottom plate of the vehicle box, and transported to the transplanting plot to achieve the purpose of seedling transportation; E. Transplanting of seedling pots: Take out the seedling pots from the seedling raising partitions that constitute the combined grid seedling raising device, and complete the transplanting operation manually or mechanically. When all the seedling pots in the seedling raising partitions are taken out, remove the seedling raising partitions to expose the next layer of seedling raising partitions, and continue to take out the seedling pots to continuously supply seedlings for the transplanting operation.

[0014] The beneficial effects of the present invention are as follows: the combined grid seedling raising device described in the present invention adopts a combined manner, in which a plurality of seedling raising partitions with fins are combined together to form a grid-shaped grid seedling raising device, and a seedling raising matrix is ​​filled into the grid in a pressing manner to form a seedling pot structure that is separated from each other, which is easy to operate; the height of the cultivated seedling pot is adjusted by adjusting the height of the seedling raising partition, which is conducive to carrying out seedling raising work at a large depth; the bottom of the seedling pot in the combined grid seedling raising device is in full contact with the lower soil, and can fully circulate water and air with the lower soil, and has strong drought resistance; the seedling pot is taken out from the notch of the seedling raising partition at an angle, which effectively avoids damage to the seedling plant due to pulling force during the seedling taking process; the combined grid seedling raising device is placed vertically for transportation, and the seedling pot is protected by the combined grid seedling raising device, which is convenient for transportation; the combined grid seedling raising device can be reused many times to reduce the cost of seedling raising.

The fin D fixing grooves 421 on both sides of the back plate D 402 have the same structure. When the fin D fixing groove 421 on one side is damaged, the fin D 401 can be inserted into the fin D fixing groove 421 on the other side, thereby increasing the service life of the back plate D 402. Multiple composite seedling raising partitions 4 are combined with the corresponding fin D fixing grooves 421 through the fins D 401 to form a regularly arranged grid-shaped grid seedling raising device.

By applying pressure to the hole pressing plate (5), the combined square seedling raising device is pressed into the seedling raising matrix layer (6), and a portion of it is left exposed outside the seedling raising matrix layer (6), so that each square in the combined square seedling raising device is filled with the seedling raising matrix. , a portion of space is reserved at the top, and under the action of the conical protrusion (501) on the pressure plate (5), a seed hole (601) is formed at the top of the seedling matrix in the grid; the other combined grid seedling raising devices are aligned and pressed into the seedling raising matrix layer (6) using the same method to complete the laying of the seedling raising devices; seeds (8) are sown in the seed holes (601), watering is performed by spraying, and then the combined grid seedling raising devices are covered with finely crushed seedling matrix and scraped flat to fill the remaining space in the grid, thereby completing precise sowing; C. Seedling management: After the crop seedlings emerge and before transplanting, water the seedling plots as needed, check the growth of the seedlings in time, remove the weak seedlings, adopt the method of replanting, and transplant healthy seedlings in the places where seedlings are missing to ensure that the seedlings are complete and strong; D. Cutting and removing seedlings: When the seedlings in the combined square seedling raising device meet the transplanting requirements, a flat shovel cutter (10) is used to cut along the bottom of the combined square seedling raising device, and a certain length of the combined square seedling raising device together with the seedling raising matrix and the seedlings inside are separated from the seedling raising matrix layer (6), so that the combined square seedling raising device forms an independent seedling pot (9) in each square; the bottom of the combined square seedling raising device including the seedling pot (9) is placed vertically on the bottom plate of the vehicle box with back to back, and transported to the transplanting plot, so as to achieve the purpose of seedling transportation; E. Seedling pot transplanting: The seedling pot (9) is taken out from the seedling raising partition that constitutes the combined grid seedling raising device, and the transplanting operation is completed manually or mechanically. When the seedling pot (9) in the seedling raising partition is completely taken out, the seedling raising partition is removed to expose the next layer of seedling raising partition, and the seedling taking work is continued to continuously supply seedlings for the transplanting operation.
