Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of seedling culture, and more particularly relates to a halocnemum strobilaceum seedling culture device and a seedling culture method. BACKGROUND

[0002] Halocnemum strobilaceum, also known as salt halo-puccinellia, yellow hair vegetables and royal seat vegetables, is an annual herbaceous plant of the Chenopodiaceae family. Halocnemum strobilaceum has the characteristics of cold resistance, waterlogging resistance and drought resistance, and can grow in intertidal zone, salt marsh and desert, and is a pioneer species for saline-alkali land improvement.

[0003] In the process of large-scale seedling culture of halocnemum strobilaceum, multi-layer seedbeds are widely used due to their high space utilization rate and large seedling density. The multi-layer seedbed is vertically arranged in a multi-layer structure, and the number of seedlings per unit area is maximized through hierarchical design. However, in order to achieve maximum space utilization, the height between adjacent cultivation layers of the traditional multi-layer seedbed is usually small, resulting in a narrow operation space between the cultivation layers. During the seedling culture process, when the staff implement seedling selection, nutrient solution supply, disease control and other seedling management operations, there are problems of blocked operation vision and limited body movement. SUMMARY

[0004] The purpose of the present application is to provide a halocnemum strobilaceum seedling culture device and a seedling culture method, which aims to realize convenient management of seedlings on a multi-layer seedbed.

[0005] In a first aspect, the present application provides a halocnemum strobilaceum seedling culture device, comprising a frame, and further comprising:

[0006] a plurality of trays, which are uniformly distributed along the vertical direction on the frame and are transversely slidably connected with the frame;

[0007] a plurality of supporting members, which are hingedly connected to the lower surface of the tray and correspond to the tray one by one; each supporting member has an elastic degree of freedom of rotating away from the extraction direction of the tray;

[0008] a plurality of limiting members, which are fixedly arranged on the frame; the limiting members correspond to the trays one by one and are located below the corresponding trays; and

[0009] a plurality of plug-in members, which are uniformly distributed along the vertical direction on the frame and correspond to the trays one by one; each plug-in member has an elastic degree of freedom of moving along the transverse direction;

[0010] When the tray is in the state of being withdrawn from the frame, the support is extended away from the tray withdrawal direction and is transversely inserted with the inserting piece, so that the frame, the tray and the support form a triangular structure.

[0011] In a possible implementation, the limiting piece has a first limiting part and a second limiting part, the first limiting part is transversely arranged, and the second limiting part is vertically arranged.

[0012] When the tray moves towards the frame, the first limiting part abuts against the support and pushes the support to rotate towards the tray.

[0013] When the tray is in the state of being withdrawn from the frame, the support is extended away from the tray withdrawal direction and is transversely inserted with the inserting piece, so that the frame, the tray and the support form a triangular structure.

[0014] In a possible implementation, the end of the support away from the hinge shaft is a socket part, the socket part has magnetism, and the inserting piece comprises:

[0015] A plug block is transversely and slidably arranged on the frame and has ferromagnetism.

[0016] A first spring is fixed at two ends with the plug block and the frame respectively and is used to push the plug block to be withdrawn from the frame.

[0017] A slot is formed in the socket part, and when the socket part is aligned with the plug block, the socket part attracts the plug block, so that the plug block is extended from the frame and is inserted with the slot.

[0018] In a possible implementation, a magnet is slidably arranged on the socket part, and the sliding direction of the magnet is perpendicular to the inserting direction of the plug block.

[0019] A second spring is fixed between the magnet and the socket part, and the second spring is used to push the magnet to be withdrawn from the slot.

[0020] When the plug block and the magnet are attracted, the plug block is inserted with the slot; when the magnet is moved out of the slot, the plug block and the magnet are separated, and the first spring pushes the plug block to be withdrawn from the slot.

[0021] In a possible implementation, the magnet is fixed with a bent portion towards one side of the insertion block, and the insertion block is provided with an opening suitable for being inserted with the bent portion, and the opening is opened along a direction perpendicular to the insertion direction of the insertion block.

[0022] When the insertion block and the magnet are attracted to each other, the bent portion is inserted with the opening.

[0023] In a possible implementation, the bent portion is provided with a pushing inclined surface, and when the insertion block moves towards the insertion slot, the insertion block is in abutment with the pushing inclined surface and pushes the bent portion to move, and the magnet always has an attractive force on the insertion block.

[0024] In a possible implementation, the insertion block is fixed with a positioning portion;

[0025] When the bent portion is inserted with the opening, the positioning portion is in abutment with the frame to limit the movement of the insertion block out of the frame.

[0026] In a possible implementation, the support comprises:

[0027] Two support rods are respectively hinged at two sides of the tray.

[0028] Two spring sheets correspond to the two support rods respectively, and one end of the spring sheet is fixed to the lower surface of the tray and the other end is in abutment with the corresponding support rod.

[0029] In a possible implementation, the frame is fixed with a plurality of slide rails in the vertical direction, and the slide rails and the tray are in sliding connection and correspond to each other.

[0030] The winged alkali plant seedling raising device provided by the application has the beneficial effects that: in the seedling raising device, a plurality of trays are distributed along the vertical direction and are in transverse sliding connection with the frame. When the workers need to perform seedling sorting, nutrient solution supply, disease prevention and control and other operations, the corresponding tray can be individually extracted from the frame. By extracting the tray, the workers have a wider operation area and are no longer limited by the adjacent tray, effectively solving the problems of blocked operation vision and limited body movement, and greatly improving the convenience and comfort of the operation.

[0031] After the tray is pulled out, the support hinged to the lower surface of the tray automatically extends towards the direction away from the tray pulling-out direction due to the elastic freedom of turning towards the direction away from the tray pulling-out direction, and is transversely inserted with the inserting piece on the frame, so that the frame, the tray and the support form a triangular structure. According to the stability principle of the triangle, the structure can provide stable support for the tray, that is, even if the staff exerts certain external force on the tray during operation, the stable triangular structure can ensure that the tray does not shake or tilt, thereby ensuring the safety of the operation process, and avoiding the damage of the seedlings caused by the instability of the tray.

[0032] When the seedling management operation is not needed, the tray can be retracted into the frame, at this time, the support extends towards the tray pulling-out direction and abuts against the limiting piece fixed on the frame, thereby limiting the rotation of the support and further limiting the pulling-out of the tray, so that the tray can be compactly stored in the frame when not in use, and the advantage of high space utilization rate of the multi-layer seedbed is maintained.

[0033] In a second aspect, the present application also provides a halocnemum strobilaceum seedling raising method, which adopts the halocnemum strobilaceum seedling raising device described above, and comprises the following steps:

[0035] Step two, prepare the seedling substrate, and fill the seedling substrate in the seedling plug;

[0036] Step three, sow the halocnemum strobilaceum seeds in the seedling plug, and place the seedling plug in the tray;

[0037] Step four, keep the substrate moist, maintain the temperature, and regularly pull out the tray to check the seedlings. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0045] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0046] Please see Figure 1 and Figure 2 A winged seepweed seedling raising device provided by the present application will be described. The winged seepweed seedling raising device comprises a frame 1, a plurality of trays 2, a plurality of supports 3, a plurality of limiting pieces 4 and a plurality of plug-in pieces 5. The plurality of trays 2 are distributed on the frame 1 in the vertical direction and are connected to the frame 1 in transverse sliding mode. The plurality of supports 3 are hingedly connected to the lower surfaces of the trays 2 and correspond to the trays 2 one by one. Each support 3 has an elastic degree of freedom of rotating towards the direction of withdrawing away from the corresponding tray 2. The plurality of limiting pieces 4 are fixedly arranged on the frame 1. The limiting pieces 4 correspond to the trays 2 one by one and are located below the corresponding trays 2. The plurality of plug-in pieces 5 are distributed on the frame 1 in the vertical direction and correspond to the trays 2 one by one. Each plug-in piece 5 has an elastic degree of freedom of moving in the transverse direction.

[0047] When the trays 2 are in the state of being withdrawn into the frame 1, the supports 3 are extended towards the direction of withdrawing away from the corresponding trays 2 and abut against the limiting pieces 4, so as to limit the rotation of the supports 3 and limit the withdrawal of the trays 2. When the trays 2 are in the state of being withdrawn from the frame 1, the supports 3 are extended towards the direction of withdrawing away from the corresponding trays 2 and are transversely plugged into the plug-in pieces 5, so as to form a triangular structure with the frame 1, the trays 2 and the supports 3.

[0048] It should be understood that the corresponding support 3, limiting piece 4 and plug-in piece 5 can not be arranged on the tray 2 close to the ground on the frame 1. Because the tray 2 close to the ground is closer to the ground, the worker can directly pull out the tray 2 and place it on the ground for operation. For the tray 2 at a higher position, if it is directly pulled out and placed on the ground, the worker needs to frequently bend down to lift the tray 2, which increases the labor intensity of the worker. The specific number of the support 3, limiting piece 4 and plug-in piece 5 arranged on the frame 1 is not limited here, and can be adjusted during production according to actual use requirements.

[0049] For the convenience of description, the end of the support 3 close to the hinge shaft is defined as the hinged end, and the other end is defined as the free end.

[0050] The tray 2 and the frame 1 are transversely slidingly connected in the device. When performing seedling sorting, nutrient solution supplementing and other operations, the worker can pull out the tray 2 from the frame 1 alone, so that the originally narrow space condition is improved. After the tray 2 is pulled out, the operation area becomes open, solving the problems of blocked operation vision and limited body movement.

[0051] When the tray 2 is pulled out, the support 3 abuts against the limiting piece 4. Since the support 3 has an elastic freedom degree of rotating away from the pulling-out direction of the tray 2, the support 3 can assist the pulling-out of the tray 2, which is convenient for the worker to pull out the tray 2.

[0052] In addition, it should be noted that the specific stiffness coefficient of the support 3 is not limited here. A support 3 with a larger stiffness coefficient can be selected, so that the support 3 can provide greater assistance when the tray 2 is pulled out. A support 3 with a smaller stiffness coefficient can also be selected, so that it is more labor-saving when the tray 2 is put into the frame 1.

[0053] When the tray 2 is pulled out, the support 3 extends away from the pulling-out direction of the tray 2 under the action of the elastic freedom degree. After the free end of the support 3 is aligned with the plug-in piece 5, the support 3 and the plug-in piece 5 are transversely plugged in. This makes the frame 1, the tray 2 and the support 3 form a triangular structure. According to the principle of triangular stability, this structure provides stable support for the tray 2. Even if the worker performs a large amplitude operation on the tray 2, the tray 2 will not shake or tilt, ensuring the safety of the operation and reducing the risk of seedling falling and damage caused by unstable tray 2.

[0054] When the tray 2 is not needed, it can be retracted into the frame 1, thereby reducing the space occupation. When the tray 2 is pushed into the frame 1, the support 3 on the tray 2 is flipped in the direction away from the tray 2. Until the support 3 abuts against the limiting part 4, when the tray 2 is continuously moved into the frame 1, the support 3 will gradually approach the lower surface of the tray 2 under the pushing of the limiting part 4. When the tray 2 is completely retracted into the frame 1, the support 3 is in a folded state and adheres to the lower surface of the tray 2. At the same time, the free end of the support 3 can abut against the limiting part 4, thereby limiting the support 3 and the tray 2, ensuring the stability of the tray 2 on the frame 1, effectively preventing the tray 2 from accidentally sliding out, and ensuring the stability of the whole device.

[0055] In some embodiments, referring to Figure 3 , the limiting part 4 has a first limiting part 41 and a second limiting part 42, the first limiting part 41 is transversely arranged, and the second limiting part 42 is vertically arranged. When the tray 2 moves into the frame 1, the first limiting part 41 abuts against the support 3 and pushes the support 3 to rotate in the direction close to the tray 2. When the tray 2 is in the state of being retracted into the frame 1, the support 3 abuts against the first limiting part 41 to limit the rotation of the support 3, and the support 3 abuts against the second limiting part 42 to limit the tray 2 from being pulled out.

[0056] When the tray 2 moves into the frame 1, the support 3 first abuts against the first limiting part 41, the first limiting part 41 pushes the support 3 to rotate in the direction close to the tray 2, so that the support 3 adheres to the lower surface of the tray 2, avoiding interference with the lower tray 2. When the tray 2 is completely retracted into the frame 1, the free end of the support 3 abuts against the first limiting part 41 to limit the rotation of the support 3, and the free end of the support 3 abuts against the second limiting part 42 to limit the tray 2 from being pulled out.

[0057] In some embodiments, referring to Figure 4 , the end of the support 3 away from the hinge shaft is a socket part 31, and the socket part 31 has magnetism. The plug-in part 5 includes a plug block 51 and a first spring 52. The plug block 51 is transversely slidably arranged on the frame 1 and has ferromagnetism. The first spring 52 is fixed at both ends of the plug block 51 and the frame 1, and is used to push the plug block 51 into the frame 1. The socket part 31 is provided with a socket 311, and when the socket part 31 is aligned with the plug block 51, the socket part 31 attracts the plug block 51, so that the plug block 51 extends out of the frame 1 and is plugged into the socket 311.

[0058] In addition, corresponding to the position of the plug block 51, a recess is arranged on the frame 1, which is matched with the shape of the socket part 31, so that when the socket part 31 is connected with the plug block 51, the socket part 31 is matched in the recess, further increasing the stability of the support 3 in use.

[0059] The socket 31 of the support 3 is magnetic, the plug 51 of the plug-in piece 5 is ferromagnetic material and is connected to the frame 1 through the first spring 52. When the tray 2 is pulled out to the socket 31 and the plug 51 are aligned, the magnetism of the socket 31 can attract the plug 51, so that it overcomes the resistance of the first spring 52 and extends from the frame 1 and is transversely plugged into the insertion slot 311, so that when the tray 2 is pulled out to a certain position, the magnetic action automatically completes the plugging process, which is simple and convenient, and compared with the traditional manual plugging method, the operation preparation time is greatly reduced and the work efficiency is improved.

[0060] In some embodiments, referring to Figure 4 , the socket 31 is slidably provided with a magnet 312, and the sliding direction of the magnet 312 is perpendicular to the plugging direction of the plug 51. The second spring 313 is fixedly arranged between the magnet 312 and the socket 31, and is used to push the magnet 312 into the insertion slot 311. When the plug 51 and the magnet 312 are attracted, the plug 51 is plugged into the insertion slot 311. When the magnet 312 is removed from the insertion slot 311, the plug 51 and the magnet 312 are separated, and the first spring 52 pushes the plug 51 out of the insertion slot 311.

[0061] Referring to Figure 4 , the magnet 312 is fixedly provided with a pressing rod 3121, which extends out of the socket 31, and pressing the pressing rod 3121 can drive the magnet 312 to move, which facilitates the staff to control the position of the magnet 312.

[0062] When it is necessary to retrieve the tray 2, the magnet 312 is moved to be misaligned with the plug 51 by pressing the pressing rod 3121. At this time, the magnetic force of the magnet 312 is not enough to continue to attract the plug 51, and the plug 51 is pulled out of the insertion slot 311 under the action of the first spring 52, so that the support 3 can be freely rotated.

[0063] In some embodiments, referring to Figure 4 , the side of the magnet 312 facing the plug 51 is fixedly provided with a bent portion 314, and the plug 51 is provided with a notch 511 adapted to be plugged with the bent portion 314, and the notch 511 is opened along a direction perpendicular to the plugging direction of the plug 51. When the plug 51 and the magnet 312 are attracted, the bent portion 314 is plugged into the notch 511.

[0064] The bending part 314 on the magnet 312 and the notch 511 of the plug block 51 can be inserted together when the plug block 51 and the magnet 312 are attracted, further enhancing the connection strength between the plug block 51 and the socket part 31, and preventing the plug block 51 from loosening. Since the insertion direction between the bending part 314 and the notch 511 is perpendicular to the insertion direction between the plug block 51 and the slot 311, it ensures that the plug block 51 is stable in the slot 311 after the bending part 314 and the notch 511 are connected, so that the plug block 51 cannot be pulled out of the slot 311, thereby ensuring the connection between the support 3 and the frame 1, and providing stable support for the tray 2.

[0065] In some embodiments, referring to Figure 4 , the bending part 314 has a pushing inclined surface 3141. When the plug block 51 moves towards the slot 311, the plug block 51 abuts against the pushing inclined surface 3141 and pushes the bending part 314 to move, and the magnet 312 always has an attractive force on the plug block 51.

[0066] The pushing inclined surface 3141 plays a guiding role, enabling the plug block 51 to be more smoothly inserted into the slot 311 and ensuring that the bending part 314 and the notch 511 are accurately inserted. In addition, due to the large size of the magnet 312, even if the magnet 312 moves due to the pushing of the pushing inclined surface 3141 during the insertion of the plug block 51, the magnet 312 can still generate sufficient magnetic force on the plug block 51, enabling the plug block 51 to move into the slot 311 and ensuring that the insertion process is successfully completed, thereby improving the success rate and accuracy of the insertion.

[0067] In some embodiments, referring to Figure 4 , the plug block 51 is fixedly provided with a positioning part 512. When the bending part 314 and the notch 511 are inserted, the positioning part 512 abuts against the frame 1 to limit the movement of the plug block 51 outwardly from the frame 1.

[0068] The positioning part 512 on the plug block 51 abuts against the frame 1 when the bending part 314 and the notch 511 are inserted, limiting the excessive movement of the plug block 51 outwardly from the frame 1. This ensures that the position of the plug block 51 is accurately consistent each time, ensuring that the bending part 314 and the notch 511 are reliably inserted, and further improving the stability and reliability of the support structure.

[0069] In some embodiments, referring to Figure 5 , the support 3 includes two support rods 315 and two spring sheets 316. The two support rods 315 are respectively hinged on the two sides of the tray 2. The two spring sheets 316 correspond to the two support rods 315 one by one. One end of the spring sheet 316 is fixed to the lower surface of the tray 2, and the other end abuts against the corresponding support rod 315.

[0070] Compared with the single support rod 315 structure, the double support rod 315 symmetric support can more evenly disperse the load on the tray 2, reducing the risk of tilting of the tray 2. When more seedling pots are placed on the tray 2, symmetric support ensures that the tray 2 remains horizontal, avoiding the risk of seedlings falling due to uneven force.

[0071] In some embodiments, referring to Figure 1 , a plurality of slide rails 11 are fixedly arranged on the frame 1 in the vertical direction, and the slide rails 11 and the tray 2 are slidably connected and correspond one-to-one.

[0072] The slide rails 11 on the frame 1 are slidably connected with the tray 2, providing precise guidance and stable support for the lateral movement of the tray 2. The design of the slide rails 11 makes the sliding of the tray 2 more smooth during extraction and retraction, reducing the friction between the tray 2 and the frame 1. The slide rails 11 limit the displacement of the tray 2 in the vertical direction and other directions, ensuring that the tray 2 only moves in the set lateral direction. This makes the position of the tray 2 more accurate during sliding, ensuring the stability and reliability of the tray 2 during extraction and retraction.

[0073] In summary, the present application provides a halocnemum strobilaceum seedling device, compared with the prior art, in the present application, a plurality of trays 2 are evenly distributed in the vertical direction and are slidably connected with the frame 1 in the lateral direction. When the worker needs to perform seedling sorting, nutrient solution replenishment, disease prevention and control and other operations, the corresponding tray 2 can be individually extracted from the frame 1. By extracting the tray 2, the worker has a wider operating area and is no longer restricted by adjacent trays 2, effectively solving the problems of blocked operation vision and limited body movement, greatly improving the convenience and comfort of the operation.

[0074] The present application also discloses a halocnemum strobilaceum seedling method, which adopts the above-mentioned halocnemum strobilaceum seedling device and comprises the following steps:

[0075] Step one, select halocnemum strobilaceum seeds with black peels, rinse with fresh water to remove impurities, and then sequentially perform disinfection treatment and seed soaking and germination. The disinfection treatment adopts 500mg / L potassium permanganate solution for 2 hours. Seed soaking and germination includes: fresh water soaking for 20-25 hours (water temperature 18-22℃) until the seeds open, or low-temperature seed soaking (5-10℃) for 6-10 hours.

[0076] Step two, mix fine sand and clay at a volume ratio of 2-2.5:1, with a particle size of 60-120 mesh, and add organic fertilizer to make the soil dry weight ratio 20:1, adjust the substrate salinity to 0.4-2.0%, and the humidity to 80-85%, to form the seedling substrate, and then fill the substrate in the seedling plug.

[0077] Step three, sow 2-4 treated seeds in each hole of the seedling plug, and cover the soil with a thickness of 2-6mm. Place the seedling plug in the tray 2.

[0078] Step four, keep the substrate moist, control the environmental temperature 13-16 ℃, and carry out the seedling raising. During the seedling raising, the tray 2 is regularly drawn out to check the seedlings.

[0079] Step five, when the seedlings reach 5-8 cm in height, the seedlings are transplanted to the tidal flat land, the transplanting depth is 5-8 cm, the plant spacing is 6-12 cm, and 0.3% urea solution is sprayed after the seedlings are thinned.

[0080] The above merely describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
