Technical Field

[0001] The present invention relates to the technical field of seedling raising, and in particular to a continuous production device and product of seedling raising trays based on straw crushing and compression. Background Art

[0002] The seedling tray is a special tool used to cultivate seedlings. It is light and easy to use, and has a scientific design. It can provide a suitable growth environment for the seedlings, thereby improving the quality and survival rate of the seedlings.

[0003] Existing seedling trays are often made of polyvinyl chloride or polyethylene, and their production requires the consumption of petroleum resources, resulting in high production costs. The recycling and disposal costs after disposal are high and they are prone to environmental pollution. In addition, polyvinyl chloride seedling trays and polyethylene seedling trays are often not breathable enough, which can easily interfere with the development of the seedling root system. To this end, a continuous production equipment and product for seedling trays based on straw crushing and compression are designed. The seedling trays made of straw have many advantages such as being biodegradable, breathable, and providing nutrients, and can effectively replace existing polyvinyl chloride seedling trays and polyethylene seedling trays. Summary of the Invention

[0004] In order to overcome the shortcomings of existing seedling trays, such as high production cost, high recycling and processing cost, and easy environmental pollution, the technical problem of the present invention is to provide a continuous production equipment and product of seedling trays based on straw crushing and compression.

[0009] As a further optimization, the crushing and stirring mechanism includes a screen drum, a fixed drum, a second motor, a rotating frame and a second scraper. The screen drum is arranged at the bottom of the guide drum, and a plurality of sieve holes are opened on the screen drum. The fixed drum is located at the bottom of the screen drum, the second motor is installed inside the fixed drum, the rotating frame is rotatably arranged in the screen drum, and the output shaft of the second motor passes through the fixed drum and is fixedly connected to the rotating frame. The second scraper is circumferentially distributed on the rotating frame, and the second scraper is in contact with the inner wall of the screen drum to cooperate with the screen drum to crush the straw.

[0010] As a further optimization, the crushing and stirring mechanism also includes a scraper. The scrapers are distributed circumferentially at the bottom of the rotating frame. The scrapers are fitted into the bottom end of the screen drum to cooperate with the screen drum to further crush the straw.

[0011] As a further optimization, the activation mechanism includes a high-voltage conductive tip, a high-voltage conductive ball and an air guide net. The high-voltage conductive tip and the high-voltage conductive ball are circumferentially spaced and arranged on the inner wall of the second shell. When the high-voltage conductive tip and the high-voltage conductive ball are energized, they are used to generate a vortex-shaped plasma wind in the second shell to plasmatize the straw fragments. The air guide net is circumferentially distributed on the inner wall of the second shell, and the mesh of the air guide net is relatively small.

[0012] As a further optimization, the compression mechanism includes a lower mold, a hydraulic cylinder, an upper mold, a guide cone, a storage slide, a sliding plate and a connecting rod.

The output shaft of the hydraulic cylinder passes through the first shell and is fixedly installed with the upper mold. The upper mold can cooperate with the lower mold. The guide cone is located in the first shell, and the storage slide is slidably arranged in the first shell. The top of the storage slide is fitted with the guide cone, and a number of material passing holes are opened on the top and bottom of the storage slide. The sliding plates are located on both sides of the storage slide. The connecting rod is rotatably arranged on one side of the sliding plate, and one end of the connecting rod is hinged to the upper mold.

[0013] As a further optimization, the compression mechanism also includes a push rod and a limit block.

[0014] As a further optimization, a seedling tray product based on straw crushing and compression includes a straw seedling tray. The straw seedling tray is made of straw crushed pieces as raw materials, bonded with urea glue and made through a cold pressing process. The straw seedling tray has a grid-distributed deformation groove, which divides the entire straw seedling tray into multiple equal-sized square areas. There is a through-type drainage hole in the center of each square area.

[0015] The beneficial effects of the present invention are: 1. The present invention relates to a straw seedling raising tray, which is made of straw as raw material and is combined with urea glue to form an easily degradable seedling raising tray. The straw seedling raising tray can be used as an ordinary seedling raising tray for seedling cultivation and can also be used as a fertilizer. During the degradation process, various nutrients required for the growth of the seedlings are produced, thereby promoting the growth of the seedlings. In addition, the decomposition of the straw seedling raising tray can also produce a small amount of formaldehyde, which effectively prevents insect pests from damaging the seedlings without harming the seedlings.

[0016] 2. The present invention relates to a straw seedling raising tray, which is made of straw as raw material. The fiber structure of the straw can effectively conserve the moisture of the culture soil in the straw seedling raising tray during the seedling raising process. Therefore, the seedlings can more effectively absorb the nutrients in the culture soil, thereby ensuring the smooth cultivation of the seedlings.

[0017] 3. The present invention relates to continuous production equipment for seedling trays. By setting an activation mechanism and a crushing and stirring mechanism, the crushing and spraying mechanism performs preliminary crushing of the straw. The activation mechanism can generate plasma wind, thereby ionizing the surface of the straw and improving the adhesion ability of the surface of the straw fragments. The crushing and stirring mechanism further crushes the straw and accelerates the contact between the plasma wind and the straw fragments through the high-speed rotation of the rotating frame, thereby promoting the adhesion ability of the surface of the straw fragments. Based on the ionization of the surface of the straw fragments, the urea glue and the straw fragments are fully mixed, thereby ensuring that when the straw is pressed into the straw seedling tray by the compression mechanism, the straw seedling tray has good mechanical strength.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1 A continuous production equipment for seedling trays based on straw crushing and compression, such as Figure 1-Figure 2As shown, it includes a first shell 1, a second shell 101, a third shell 102 and a supporting shell 103. The second shell 101 is located at the top of the first shell 1, the third shell 102 is located at the top of the second shell 101, and the supporting shell 103 is arranged on one side of the third shell 102. It also includes a crushing and spraying mechanism 2, a crushing and stirring mechanism 3, an activation mechanism 4 and a compression mechanism 5. The crushing and spraying mechanism 2 is located in the third shell 102 and is used to crush the bundled straw and perform preliminary crushing on the straw. The crushing and stirring mechanism 3 is located in the second shell 101 and is used to further crush the straw and make the straw into powder. The activation mechanism 4 is located in the second shell 101 and is used to generate plasma wind. The plasma wind can ionize the surface of the straw and enhance the adhesion ability of the straw surface through the attraction effect of ionization. The compression mechanism 5 is located in the first shell 1 and is used to cold-press the straw powder to form a straw seedling tray 6.

[0022] like Figure 2-Figure 3 As shown, the crushing and spraying mechanism 2 includes a first motor 201, a first crushing roller 202, a second crushing roller 203 and a gear set 204. The first motor 201 is installed on the support shell 103. The first crushing roller 202 and the second crushing roller 203 are rotatably connected to the third shell 102. The circumferential surfaces of the first crushing roller 202 and the second crushing roller 203 are ratchet-shaped, and the tooth surfaces of the two are in opposite directions. The tooth surfaces of the first crushing roller 202 and the second crushing roller 203 are staggered. The output shaft of the first motor 201 passes through the support shell 103 and is fixed to the first crushing roller 202. The gear set 204 includes a driving gear and a driven gear that are meshed with each other. The driving gear and the driven gear are both rotatably connected to one side of the support shell 103. The driving gear is fixed on the first crushing roller 202, and the driven gear is fixed on the second crushing roller 203. When the first motor 201 is started, the first crushing roller 202 and the second crushing roller 203 are driven to rotate in opposite directions through the gear set 204.

[0023] like Figure 2-Figure 3As shown, the crushing and spraying mechanism 2 also includes an auxiliary roller 205, a belt transmission group 206 and a first scraper 207. The auxiliary roller 205 is mirror-distributed and rotatably connected to the inner wall of the third shell 102, and the mirror-distributed auxiliary rollers 205 are respectively matched with the first crushing roller 202 and the second crushing roller 203. The circumferential surface of the auxiliary roller 205 is in the shape of a ratchet gear. The tooth surfaces of the mirror-distributed auxiliary rollers 205 are respectively in the same direction as the adjacent first crushing rollers 202 and the second crushing rollers 203, so that the tooth surfaces of the auxiliary rollers 205 can cooperate with the tooth surfaces of the first crushing rollers 202 and the second crushing rollers 203 to crush the straw. The belt transmission group 206 includes a driving wheel, a secondary wheel, and a secondary wheel. The driving wheel and the transmission belt, the active wheel and the driven wheel are all mirror-distributed and rotatably connected to one side of the third shell 102. The active wheel of one belt transmission group 206 is fixedly connected to the first crushing roller 202, and the driven wheel is fixedly connected to the auxiliary roller 205 close to the first crushing roller 202. The transmission belt is sleeved on the active wheel and the driven wheel. The active wheel of the other belt transmission group 206 is fixedly connected to the second crushing roller 203, and the driven wheel is fixedly connected to the auxiliary roller 205 close to the second crushing roller 203. The first scraper 207 is mirror-distributed and arranged on the top of the third shell 102, and the first scraper 207 is in contact with the auxiliary roller 205 to clean the straw fragments remaining on the auxiliary roller 205.

[0024] like Figure 2 As shown, the crushing and spraying mechanism 2 also includes a guide cylinder 208 and a glue valve 209. The guide cylinder 208 is located at the bottom of the third shell 102, and the glue valve 209 is circumferentially distributed in the guide cylinder 208. When the glue valve 209 is opened, urea glue can flow out. Urea glue is an adhesive resin that can effectively bond straw fragments and straw chips.

[0025] like Figure 4-Figure 5 As shown, the crushing and stirring mechanism 3 includes a screen drum 301, a fixed drum 302, a second motor 303, a rotating frame 304 and a second scraper 305. The screen drum 301 is arranged at the bottom of the guide drum 208, and a plurality of screen holes are opened on the screen drum 301. The fixed drum 302 is located at the bottom of the screen drum 301. The second motor 303 is installed inside the fixed drum 302. The rotating frame 304 is rotatably arranged in the screen drum 301, and the output shaft of the second motor 303 passes through the fixed drum 302. The drum 302 is fixedly connected to the rotating frame 304, and the second scraper 305 is circumferentially distributed on the rotating frame 304, and the second scraper 305 is in contact with the inner wall of the screen drum 301. When the second motor 303 is started, the second scraper 305 rotates at a high speed to squeeze the straw fragments into the sieve holes of the sieve drum 301. The shear stress generated by the sieve holes of the sieve drum 301 and the second scraper 305 on the straw fragments quickly and multiple times cuts the straw, thereby further crushing the straw into fine pieces.

[0026] like Figure 4-Figure 5As shown, the crushing and stirring mechanism 3 also includes a scraper 306. The scrapers 306 are circumferentially distributed at the bottom of the rotating frame 304. The scrapers 306 are in contact with the bottom end of the screen drum 301 and are used to squeeze the straw fragments into the sieve holes of the screen drum 301. The shear stress generated by the sieve holes of the screen drum 301 and the scraper 306 on the straw fragments is crushed into pieces.

[0027] like Figure 4 As shown, the activation mechanism 4 includes a high-voltage conductive tip 401, a high-voltage conductive ball 402 and an air guide net 403. The high-voltage conductive tip 401 and the high-voltage conductive ball 402 are circumferentially spaced and fixed to the inner wall of the second shell 101. When high voltage electricity is passed through the high-voltage conductive tip 401 and the high-voltage conductive ball 402, a strong electric field can be generated, thereby ionizing the air around the electric field, and then generating a vortex-shaped plasma wind in the second shell 101 to plasmatize the straw fragments. The air guide net 403 is circumferentially distributed and fixed to the inner wall of the second shell 101. The mesh of the air guide net 403 is small, so that the air guide net 403 can ensure that the plasma wind passes through itself while also guiding the plasma wind to flow toward the straw fragments.

[0028] like Figure 5-Figure 7 and Figure 9 As shown, the compression mechanism 5 includes a lower mold 501, a hydraulic cylinder 502, an upper mold 503, a guide cone 504, a storage slide 505, a sliding plate 506 and a connecting rod 507. The lower mold 501 is fixedly connected to the first shell 1, and the hydraulic cylinder 502 is installed on the first shell 1. The output shaft of the hydraulic cylinder 502 passes through the first shell 1 and is fixedly connected to the upper mold 503. The upper mold 503 can cooperate with the lower mold 501. The upper mold 503 is provided with a grid-shaped protrusion, and the lower mold 501 is provided with a columnar protrusion. The cone 504 is fixed to the top of the inside of the first shell 1, and the storage slide 505 is slidably connected to the first shell 1. The top of the storage slide 505 is in contact with the guide cone 504 to prevent the guide cone 504 from leaking straw fragments during the sliding process of the storage slide 505. Several material holes are provided at the top and bottom of the storage slide 505. The sliding plate 506 is fixed to both sides of the storage slide 505. The connecting rod 507 is hinged to one side of the sliding plate 506, and one end of the connecting rod 507 is hinged to the upper mold 503.

[0029] like Figure 6-Figure 8As shown, the compression mechanism 5 also includes a push rod 508 and a limit block 509. The push rod 508 is rectangularly distributed and slidably arranged at the bottom of the lower mold 501. Two guide grooves for guiding the sliding of the push rod 508 are opened on one side of the sliding plate 506. The bottom of the push rod 508 is slidably connected to the guide groove of the sliding plate 506, so that the guide groove guides the push rod 508 to move up and down. The two guide grooves are staggered up and down so that they cannot be connected to each other, thereby avoiding the movement of the push rod 508 in one guide groove from being interfered with by the other guide groove. A rotating groove is opened on one side of the sliding plate 506, and the rotating groove is connected to the guide groove. The limit block 509 is rotatably connected to the inside of the rotating groove. The rotating groove limits the rotation range of the limit block 509, and a spring is connected between the limit block 509 and the rotating groove.

[0030] like Figure 10-11 As shown, a seedling raising tray product based on straw crushing and compression includes a straw seedling raising tray 6. The straw seedling raising tray 6 is made of straw crushed pieces as raw materials, bonded by urea glue and subjected to a cold pressing process. The fiber structure of the straw crushed pieces has better air permeability and water conservation capacity. The bottom of the straw seedling raising tray 6 is provided with a grid-distributed deformation groove 602 formed by the cold pressing process. The deformation groove 602 cleverly divides the bottom of the entire straw seedling raising tray 6 into a plurality of equal-sized square areas. The cold pressing process also leaves a through-type drainage hole 601 at the center of each square area. The drainage hole 601 facilitates the timely discharge of excess water in the seedling raising process, effectively promotes the root respiration of the seedlings, and thereby prevents the roots of the seedlings from being soaked for a long time and causing rot.

[0031] The staff first drives the straw baler, which collects and bales the straw in the cultivated land, then rinses the straw with clean water and sterilizes it with steam at high temperature to prevent the straw seedling tray 6 made of straw from producing toxicity and harming the seedlings. The washed straw is put into the straw dryer and the hot air is used to quickly dry the straw, thus completing the drying and cleaning requirements of the straw during straw processing (the collection, washing and drying of the straw are all existing technologies, so they will not be described in detail); after the straw is dried, the straw is processed into the straw seedling tray 6, The staff starts the first motor 201, so that the output shaft of the first motor 201 drives the first crushing roller 202 to rotate counterclockwise, and at the same time, the first crushing roller 202 drives the second crushing roller 203 to rotate clockwise through the gear group 204. During the rotation, the first crushing roller 202 drives the adjacent auxiliary roller 205 to rotate synchronously in the same direction through one of the belt transmission groups 206. During the rotation, the second crushing roller 203 drives the adjacent auxiliary roller 205 to rotate synchronously in the same direction through another belt transmission group 206. Then the staff puts the bundled straw into the crushing and spraying mechanism 2. When the straw contacts the first crushing roller 202 and the second crushing roller 203, the tooth surfaces of the first crushing roller 202 and the second crushing roller 203 will squeeze the straw to move downward. The tooth surfaces of the first crushing roller 202 and the second crushing roller 203 are misaligned and matched, so that the straw is misaligned and squeezed, thereby subjecting the straw to huge stress. The straw is broken under the action of the huge stress and falls down to wait for further processing. In addition, during the rotation, the first crushing roller 202 drives the adjacent auxiliary roller 205 through one of the belt transmission groups 206. The belt drive group 206 drives the auxiliary roller 205 adjacent to it to rotate in the same direction, so that the tooth surface of the auxiliary roller 205 is misaligned with the tooth surface of the first crushing roller 202 to squeeze and crush the straw. Similarly, during the rotation process, the second crushing roller 203 drives the auxiliary roller 205 adjacent to it to rotate in the same direction through another belt drive group 206, so that the tooth surface of the auxiliary roller 205 is misaligned with the tooth surface of the second crushing roller 203 to squeeze and crush the straw. The first crushing roller 202, the second crushing roller 203 and the auxiliary roller 205 rotate together to crush the straw, thereby achieving preliminary crushing of the straw.

[0032] It is worth noting that in the process of the first crushing roller 202, the second crushing roller 203 and the auxiliary roller 205 rotating together to crush the straw, the straw will adhere to the first crushing roller 202, the second crushing roller 203 and the auxiliary roller 205 due to the squeezing and its own fiber structure, wherein the first crushing roller 202 and the second crushing roller 203 will cooperate with the rotation of the auxiliary roller 205 to make the auxiliary roller 205 rub the straw fragments on the first crushing roller 202 and the second crushing roller 203, thereby causing the auxiliary roller 205 to drive the first crushing roller The straw fragments on the first crushing roller 202 and the second crushing roller 203 fall off, and the straw fragments on the auxiliary roller 205 will be scraped off by the first scraper 207, thereby separating from the auxiliary roller 205 and falling downward. The straw fragments on the first crushing roller 202, the second crushing roller 203 and the auxiliary roller 205 are scraped off, which can effectively prevent the straw fragments from accumulating on the first crushing roller 202, the second crushing roller 203 and the auxiliary roller 205 to hinder the straw crushing process, thereby improving the crushing efficiency of the first crushing roller 202, the second crushing roller 203 and the auxiliary roller 205.

[0033] After the initial crushing of the straw, the straw fragments will fall on the screen drum 301. During the falling process of the straw fragments, the staff will pass high-voltage positive charge to the high-voltage conductive tip 401 and simultaneously pass high-voltage negative charge to the high-voltage conductive ball 402, thereby forming a high-voltage electric field between the high-voltage conductive tip 401 and the high-voltage conductive ball 402. The high-voltage electric field will ionize the surrounding air and ionize the air. The ionized air will flow counterclockwise along the direction of the electric field under the action of the high-voltage electric field, thereby forming plasma wind. On the one hand, a part of the plasma wind will pass through the air guide net 403 to form a ring cycle, ensuring the smooth flow of the plasma wind at the high-voltage conductive tip 401 and the high-voltage conductive ball 402. On the other hand, Figure 4 As shown, due to the inclined setting of the air guide net 403, another part of the plasma wind will be blocked by the air guide net 403, and thus flow in a spiral shape toward the middle along the air guide net 403. At this time, the plasma wind will pass through the sieve holes of the screen cylinder 301 and blow onto the falling straw fragments, thereby ionizing the surface of the straw fragments, thereby enhancing the adhesion ability of the straw fragments. At the same time, the staff starts the glue valve 209, opens the glue valve 209 and flows out the configured urea glue, and the urea glue will flow downward along the guide cylinder 208, thereby adhering to the straw fragments in the sieve cylinder 301 along the screen cylinder 301. Since the surface of the straw fragments has been ionized, the urea glue will quickly infiltrate the straw fragments, thereby increasing the adhesion ability of the urea glue to the straw fragments, which helps to improve the mechanical strength of the straw seedling tray 6 during molding, thereby ensuring the production quality of the straw seedling tray 6.

[0034] When the urea glue contacts the straw fragments, the staff starts the second motor 303, so that the rotating shaft of the second motor 303 drives the rotating frame 304 to rotate counterclockwise at a high speed, and the rotation of the rotating frame 304 drives the second scraper 305 and the scraper 306 to rotate synchronously. On the one hand, the rotation of the second scraper 305 and the scraper 306 will fully mix the urea glue with the straw fragments, thereby improving the wetting effect and bonding effect of the urea glue on the straw fragments, and the rotation of the rotating frame 304 will further promote the spiral flow of the plasma wind, accelerate the contact between the plasma wind and the straw fragments, and then promote the ionization of the surface of the straw fragments. On the other hand, the second scraper 305 and the scraper 306 squeeze the straw fragments during the rotation process, and the straw fragments are squeezed in the sieve holes of the scraper 306 and the sieve drum 301. The straw fragments are further crushed into straw crumbs by the cooperation of the second scraper 305 and the sieve holes of the screen drum 301, thereby further crushing the straw fragments into straw crumbs. Since the straw crumbs are soaked in urea glue, the straw crumbs will move in the form of clumps with certain flow properties. It is worth noting that in the initial state, the feeding hole of the storage slide 505 is located at the bottom of the guide cone 504, so the clumping straw crumbs will flow out along the sieve holes of the screen drum 301 and fall onto the storage slide 505 along the guide cone 504. At this time, the straw crumbs will enter the interior of the storage slide 505 along the feeding hole at the top of the storage slide 505, completing the further crushing and transfer of the straw.

[0035] When the storage slide 505 is full of straw fragments, the staff can carry out cold pressing of the straw seedling tray 6. It is worth noting that in the initial state, since the material passage hole of the storage slide 505 is located at the bottom of the guide cone 504, the output end of the hydraulic cylinder 502 is in an extended state, so that the upper mold 503 and the lower mold 501 are in a mold closing state. The staff starts the hydraulic cylinder 502 to make the output end of the hydraulic cylinder 502 contract upward, thereby driving the upper mold 503 to separate from the lower mold 501 and move upward. In the process of moving upward, the upper mold 503 drives the sliding plate 506 to move horizontally along the first shell 1 close to the lower mold 501 through the connecting rod 507. At the same time, the sliding plate 506 drives the storage slide 505 to move synchronously. When the storage slide 505 slides to above the lower mold 501, the straw fragments in the storage slide 505 will move along the storage The material flow through the through hole at the bottom of the sliding frame 505 flows downward, thereby gradually filling the lower mold 501. Then the staff restarts the hydraulic cylinder 502, so that the output end of the hydraulic cylinder 502 extends downward, thereby driving the upper mold 503 downward to approach the lower mold 501. In the process of moving downward, the upper mold 503 drives the sliding plate 506 to move horizontally along the first shell 1 away from the lower mold 501 through the connecting rod 507. At the same time, the sliding plate 506 drives the storage sliding frame 505 to move synchronously to complete the reset. When the storage sliding frame 505 is reset, the upper mold 503 and the lower mold 501 are re-closed. At this time, the upper mold 503 squeezes the straw fragments inside the lower mold 501. Under the squeezing of the upper mold 503, the straw fragments are spliced ​​with high strength through their own fiber structure and the impregnated urea glue, and are thus cold-pressed to form a straw seedling tray 6. It is worth noting that Figure 9 As shown, the upper mold 503 is provided with a grid-like protrusion, so that when the upper mold 503 is used to cold-press the straw crushed pieces, the straw crushed pieces are squeezed by the grid-like protrusions of the upper mold 503 to form grid-distributed deformation grooves 602, and the lower mold 501 is provided with a columnar protrusion, so that when the lower mold 501 is used to cold-press the straw crushed pieces, the straw crushed pieces are squeezed by the columnar protrusions of the lower mold 501 to form a plurality of drainage holes 601.

[0036] When the sliding plate 506 is moved, the guide groove of the sliding plate 506 controls the movement of the push rod 508 in the vertical direction. Specifically, when the sliding plate 506 is close to the lower mold 501, the bottom of the push rod 508 is located at the bottom of the guide groove of the sliding plate 506. The sliding plate 506 drives the limit block 509 to move synchronously during the movement. When the limit block 509 contacts the push rod 508, the limit block 509 is restricted by the rotation groove of the sliding plate 506, so that the limit block 509 restricts the movement direction of the push rod 508, so that the push rod 508 moves upward along the guide groove of the sliding plate 506. When there is a cold-pressed straw seedling tray 6 in the lower mold 501, the straw seedling tray 6 will be pushed upward by the push rod 508, so that the sliding plate 506 contacts and pushes the straw seedling tray 6 to move during the movement, so that the straw seedling tray 6 gradually separates from the mounting plate After the push rod 508 passes around the top of the limit block 509, the limit block 509 loses the squeezing of the push rod 508, thereby releasing the spring and driving the limit block 509 to reset.

[0037] Example 2 On the basis of Example 1, Figure 10-11As shown, the straw seedling tray 6 can be used for raising seedlings after production is completed. During the use of the straw seedling tray 6, the culture soil is first spread in the straw seedling tray 6, and the seeds are planted in the culture soil. The straw seedling tray 6 is placed in a suitable temperature environment and watered in time. The seeds gradually take root and grow into seedlings until the root system expands to the entire seedling tray. Since the straw seedling tray 6 is made of straw, the fiber structure of the straw crushed has better air permeability, so the gas in the culture soil can exchange gas with the outside world faster through the fiber structure of the straw crushed, thereby promoting the growth of the seedlings. The root respiration of the seedlings is promoted. During the process of watering the seedlings, the fiber structure inside the straw seedling tray 6 can better conserve the moisture in the culture soil, so that the seedlings can absorb the nutrients in the culture soil more effectively, thereby ensuring the smooth cultivation of the seedlings. The excess moisture flows out of the straw seedling tray 6 through the drainage hole 601, so that the excess moisture in the straw seedling tray 6 is discharged in time, further promoting the root respiration of the seedlings, thereby preventing the roots of the seedlings from being soaked for a long time and causing rot. In addition, the urea gel in the straw seedling tray 6 contains urea, which can provide sufficient nitrogen elements for the seedlings and promote the growth of the seedlings.

[0038] When the seedlings grow up and can be transplanted and planted, the staff can significantly deform and bend the deformation groove 602 of the straw seedling tray 6 half an hour after watering the seedlings. Since the deformation groove 602 of the straw seedling tray 6 is thinner than other parts, the U-shaped structure of the deformation groove 602 is more easily deformed, and the fiber structure inside the straw seedling tray 6 will expand after absorbing water, causing internal stress inside the straw seedling tray 6. Therefore, the deformation groove 602 of the straw seedling tray 6 will break after being significantly deformed and bent, thereby dividing the straw seedling tray 6 into Multiple fragments can be planted in cultivated land together with seedlings. Since the main component of the fragments is straw fragments, the fragments are easily decomposed by microorganisms in the soil when buried in the soil, producing a large amount of inorganic salts required by the seedlings, providing the required nutrients for the seedlings, and promoting the growth of the seedlings. In addition, urea glue will decompose along with the fragments. Urea glue will continue to produce a small amount of formaldehyde during the decomposition process of microorganisms. A small amount of formaldehyde will drive insects away from the seedlings, and the formaldehyde concentration will not exceed the tolerance range of the seedlings, so that the formaldehyde produced by the decomposition of the fragments can protect the root system of the seedlings, reduce the damage to the seedlings by insect pests and bacteria, and achieve protection of the seedlings.
