Description

Technical Field

[0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a straw-degradable nutrient seedling cultivation tray and a seedling cultivation method. Background Art

[0002] When cultivating seedlings, it is sometimes necessary to use seedling trays. In the prior art, seedling trays are mostly made of plastic materials. Plastic materials cannot be effectively degraded in nature. When users transplant seedlings, they need to take the seedlings out of the seedling trays. After the seedlings are planted, the seedling trays need to be recycled to avoid affecting the growth of the seedlings in the fields.

[0003] Currently, some domestically developed seedling trays are made from crushed crop straw, typically one or more of corn stalks, rice straw, bran, thatch, bamboo powder, and wood powder, using hot pressing. Key patents include CN1125502, CN1194773, CN1268283, and CN1557128. Hot pressing requires the use of adhesives, with urea-formaldehyde resin being the primary adhesive used for flower pots, and polyacrylamide and oxidized starch as the primary adhesives used for seedling containers. With the development of modern agriculture, container seedling cultivation is becoming increasingly widespread. Both domestically and internationally, vegetable, flower, and seedling cultivation methods are shifting from traditional open-field cultivation to container-based methods.

[0004] However, the existing method of using crop straw to make seedling trays still has certain inconveniences during implementation.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Depend on Figure 1-9 The present invention discloses a straw degradation nutrient seedling raising tray, comprising a tray portion 1, a bottom lining plate 3, a horizontal separation piece, and a vertical separation piece.

[0038] The plate portion 1 is provided with a plurality of rectangular plate units 2, each of which has a horizontal gap and a vertical gap, and is a trapezoidal structure with a larger upper portion and a smaller lower portion. The plate portion 1 is made of straw material. During the seedling cultivation process, the plate portion 1 will gradually decompose, thereby reducing the adhesion between each plate unit 2. That is, a smaller force is used to achieve the purpose of separating the plate units 2.

[0039] By using the tray 1 made of straw, not only can the straw be decomposed to provide nutrition for the seedlings during cultivation, but the tray 1 can also be directly transplanted when the seedlings are transplanted, avoiding the use of plastic and the possible impact on the cultivation and transplantation of the seedlings.

[0040] The disk 1 is placed on the bottom lining plate 3, and a slider 4 is fixed to the side of the bottom lining plate 3. The horizontal separator and the vertical separator are both located above the bottom lining plate 3, and the horizontal separator is located in the horizontal gap, the vertical separator is located in the vertical gap, and the horizontal separator is located above the vertical separator.

[0041] By using the horizontal separators and the vertical separators, the tray portion 1 can be divided into separate tray units 2 when the seedlings need to be transplanted, so as to facilitate the transplantation of the seedlings. The bottom lining plate 3 can also support the tray portion 1 so that the tray portion 1 can be moved.

[0042] The transverse separation member includes a first rotating rod 5 and a transverse rod 8. The transverse rod 8 passes through the transverse gap, and there are multiple transverse rods 8. The first rotating rod 5 can rotate, and when the first rotating rod 5 rotates, the transverse rods 8 can move in sequence to divide the disk portion 1 into transverse strip structures.

[0043] The vertical separation member includes a second rotating rod 9 and a vertical rod 11. The second rotating rod 9 can rotate, and when the second rotating rod 9 rotates, the vertical rod 11 can move in sequence to divide the horizontal strip structure into individual disk units 2. The vertical rods 11 that move in sequence can facilitate the division of the strip structure of the disk part 1.

[0044] When the device is implemented, soil is filled into the disc unit 2, and then seeds are planted in the disc unit 2 to cultivate the seeds. After the seeds are cultivated and become seedlings, when the user transplants the seedlings, the horizontal separator first divides the disc portion 1 into a horizontal strip structure, and then the vertical separator divides the strip structure into individual disc units 2, thereby making it convenient for the user to transplant the seedlings.

[0045] The first rotating rod 5 is covered with a first fixed block 7. The number and position of the first fixed blocks 7 correspond to the horizontal gap. The first fixed block 7 has an annular groove 14. A shift block 15 is fixed to the outside of the first rotating rod 5. A push block 16 is provided inside the first fixed block 7. The push block 16 is rotatably arranged inside the first fixed block 7. The shift block 15 can contact the push block 16 so that when the first rotating rod 5 rotates, the push block 16 can be pushed and rotated. An end block 17 is inserted at the lower end of the first fixed block 7, and the first fixed block 7 and the end 17 will not be separated. The end block 17 is fixed to the cross bar 8, and when the push block 16 is pushed, the end block 17 can drive the cross bar 8 to move.

[0046] The cross bar 8 is located at the top end of the transverse gap. When the cross bar 8 moves, the cross bar 8 can separate the disc unit 1 due to the easy separation of the disc portion 1 made of straw.

[0047] Each first fixed block 7 is provided with a shift block 15, and multiple shift blocks 15 are arranged in sequence on the circumferential surface of the first rotating rod 5, and the transverse surface of the shift block 15 is an inclined surface, so that when the shift block 15 rotates, the shift block 15 can push the push block 16. When the shift block 15 and the push block 16 just come into contact, the push block 16 cooperates with the thinner part of the shift block 15. As the shift block 15 rotates, the thicker area of ​​the shift block 15 comes into contact with the push block 16, thereby pushing the push block 16. Only when the previous shift block 15 is separated from the corresponding push block 16 can the next shift block 15 come into contact with the corresponding push block 16, so as to ensure that the disk portion 1 is divided into separate strip structures. The vertical surface of the shift block 15 is a vertical surface, and the length of the vertical surface on the first rotating shift block 15 to the vertical surface of the last rotating shift block 15 decreases in sequence, so that after the disk portion 1 is divided into separate strip structures, each strip structure is separated from each other.

[0048] Taking the shift block 15 with the thickest vertical surface as the starting point, in the early stage of separating the disc portion 1, since the separated part is lighter than the unseparated part, the unseparated part can remain relatively still under the action of gravity. However, when the splitting operation reaches the end (when the two strip structures are separated), pulling one of the strip structures will inevitably cause the two strip structures to move together. Therefore, the following technical solution is provided: the lower end surface of the pushing block 16 in the first fixed block 7 at the end is an arcuate surface, and the interior of the end block 17 at the end is provided with a transmission wheel 34 and a rotating wheel 33, and the arcuate surface and the transmission wheel 34 are connected. The driving wheels 34 mesh with each other, and the transmission wheel 34 meshes with the rotating wheel 33. Two symmetrically arranged push plates 30 are disposed within the end block 17 at the distal end. The push plates 30 extend into the crossbar 8 and are secured to a bracket 32 ​​that meshes with the rotating wheel 33. The push plates 30 and the end block 17 are connected by a second spring 31. When the push block 16 rotates, the lower end of the push block 16 drives the transmission wheel 34, which in turn drives the rotating wheel 33. The brackets 32 are located on either side of the rotating wheel 33, allowing the two push plates 30 to move away from each other, separating the two strip-like structures. In some embodiments, the push block 16 can directly engage with the rotating wheel 33 without the need for a transmission wheel 34.

[0049] Of course, when the device is implemented, in order to ensure that each strip structure can be separated, the structure of each cross bar 8 can be set to this style, that is, each cross bar 8 has a structure with two push plates 30.

[0050] A first spring 26 is provided between the first fixed block 7 and the end block 17 to enable the first fixed block 7 to be reset. The matching relationship between the first rotating rod 5, the horizontal rod 8 and the second rotating rod 9, the vertical rod 11 is the same, that is, the structure of the horizontal separation piece and the vertical separation piece is the same.

[0051] It also includes an outer frame 18, in which a transverse slide is provided, the bottom lining plate 3 is located in the transverse slide, a fixed plate 23 is fixedly connected to the inner wall of the transverse slide, the slider 4 is located above the fixed plate 23, and a plurality of through holes 24 are opened on the fixed plate 23. The slider 4 can slide down along the through holes 24, and a screw 27 is provided in the outer frame 18. A threaded block 28 is provided on the outer sleeve of the screw 27. A limit block 29 is fixed to the threaded block 28. The limit block 29 cooperates with the slider 4. When the screw 27 rotates, the threaded block 28 can slide to push the slider 4 to slide.

[0052] A first toggle block 19a and a second toggle block 19b are fixed to the inner wall of the horizontal slide. The first toggle block 19a and the second toggle block 19b can cooperate with the first tooth portion 6 to rotate the first tooth portion 6. The first tooth portion 6 is fixed to the end of the first rotating rod 5 so that the first tooth portion 6 drives the first rotating rod 5 to rotate. A vertical tooth portion 25 is also provided on the inner wall of the horizontal slide. The second tooth portion 10 at the end of the second rotating rod 9 can cooperate with the vertical tooth portion 25 so that when the bottom lining plate 3 moves downward, the second tooth portion 10 can drive the second rotating rod 9 to rotate.

[0053] A support rod 20 is fixed to the first fixed block 7. The end of the support rod 20 is rectangular, and a rectangular groove is provided in the transverse slide to prevent the support rod 20 from rotating with the first rotating rod 5. At the same time, when the bottom lining plate 3 moves downward, the support rod 20 can also fix the position of the first rotating rod 5 and the cross bar 8 to prevent them from moving downward together.

[0054] The horizontal slide also has a movable plate 21, and a block 22 is fixed to the upper end of the movable plate 21. A slot 13 is provided at the lower end of the bottom lining plate 3. The block 22 cooperates with the slot 13 so that the bottom lining plate 3 can move up and down with the movable plate 21. That is, when the block 22 cooperates with the slot 13, when the movable plate 21 moves downward, the movable plate 21 can pull the bottom lining plate 3 to move downward. A lifting member is provided at the lower end of the movable plate 21.

[0055] A method for raising seedlings using a straw-degradable nutrient seedling tray comprises the following steps:

[0056] Step 1: Fill the tray unit 2 with soil and plant the seeds in the tray unit 2.

[0057] Step 2: When the seedlings need to be transplanted, the tray 1 is placed on the bottom lining 3, and the bottom lining 3 slides in the horizontal slide.

[0058] Step 3: During the sliding process, the disk portion 1 is first divided into strip-shaped units, and then the strip-shaped units are divided into individual disk units 2.

[0059] Step 4: transplant the seedlings in the tray unit 2.
