Description

Technical Field

[0001] The present invention relates to the technical field of rice planting, and in particular to a sowing device for identifying disease resistance of rice varieties and a preparation process thereof. Background Art

[0002] Currently, the selection, breeding, identification, evaluation, and utilization of disease-resistant crop varieties have received significant attention from government departments at all levels. my country's Ministry of Agriculture has also implemented a "veto system" for highly susceptible varieties to prevent the serious losses caused by the use of less resistant varieties in production.

[0003] To identify rice disease resistance, different rice varieties must be sown in the resistance identification plot. During this process, seeds of different varieties must not be mixed, as this can lead to inaccurate identification results. Therefore, it is crucial to utilize the planting space in the identification plot effectively and to sow different rice varieties in isolated areas. Traditional sowing methods typically use standard seedling trays or draw grids on mud. For standard seedling trays, mud is poured into a seeding cup before sowing. The seeding tray is then placed into the mud, ensuring the tray surface is level with the mud. During sowing, the seeds are sown onto the mud in the seeding cup.

[0004] Prior art CN 108496631 A discloses a sowing device for identifying disease resistance in rice varieties, comprising a sowing tray and a packaging assembly. The sowing tray includes a tray and a plurality of sowing cups arranged in an array on the tray. The sowing cups are transparent from top to bottom and have water-permeable holes in their peripheral walls. The tray is connected to the middle of the outer wall of the sowing cups. The packaging assembly includes a plurality of packaging parts for packaging seeds and used in conjunction with the sowing cups. The packaging parts are made of a water-soluble material. The advantages of the present invention are: 1. The sowing cups are transparent from top to bottom, and their transparent bottom design can promote the development of the root system of rice seedlings. 2. The packaging parts are made of a water-soluble material and are used to package seeds and work in conjunction with the sowing cups. The seeds are sorted and loaded into the packaging parts before sowing, effectively preventing confusion between different varieties due to seeds falling during sowing.

[0005] However, the above prior art has the following problems:

[0006] (1) During the seeding process, a seeding device is generally used to suspend and drop rice seeds, which easily causes the rice seeds to bounce and roll, resulting in inaccurate positioning of the rice seeds. As a result, the spacing between the seeds cannot be arranged in the expected array, and it is easy to cause confusion among multiple varieties, which is not convenient for subsequent observation of the growth of rice seedlings.

[0007] (2) After rice seeds are sown, they usually need to be watered several times before they germinate and take root. After spraying water, seeds are prone to drift, causing confusion between different varieties, which also affects the accuracy of identification results.

[0008] Therefore, it is necessary to provide a sowing device and a preparation process for identifying disease resistance of rice varieties to solve the above technical problems. Summary of the Invention

[0009] The present invention overcomes the deficiencies of the prior art and provides a sowing device and a preparation process for identifying disease resistance of rice varieties.

[0010] To achieve the above-mentioned object, the technical solution adopted by the present invention is: a preparation process of a rice variety disease resistance identification and sowing device, comprising the following steps:

[0013] S3. Insert a catheter into the accommodation space from above the interpenetrating space, and blow air into the accommodation space through the catheter. After the accommodation space swells in all directions under the action of the air, remove the catheter.

[0014] S4. Sprinkle wheat seeds into the containing space, glue the connecting position between the interlaced space and the containing space, and cut off the excess parts under the interlaced space and the water flow channel, then divide the long strip structure into multiple seed belts, arrange them in order and place them on the seedling tray.

[0015] In a preferred embodiment of the present invention, in S1, the shape of the groove is semi-cylindrical, and the groove is provided between two adjacent depressions.

[0016] In a preferred embodiment of the present invention, in S2, the interlaced space is semi-elliptical, semi-circular or semi-oval, and a slope is provided at the bottom of the interlaced space, the slopes are arranged opposite to each other, and the slopes are arranged inclined toward the middle.

[0017] In a preferred embodiment of the present invention, in S2, the water flow channel is provided at the upper portion of the accommodating space for connecting two adjacent accommodating spaces.

[0018] In a preferred embodiment of the present invention, in S2, the shape of the accommodation space is trapezoidal, rectangular or oval.

[0019] In a preferred embodiment of the present invention, in said S4, the wheat seeds first fall into the interlaced space and then fall from the interlaced space into the accommodating space; the excess portion to be cut off refers to the portion below the water flow channel and between adjacent accommodating spaces.

[0020] In a preferred embodiment of the present invention, in S4, a number of dotted scratches are cut along the width direction of the long strip structure. The dotted scratches are evenly distributed along the length direction of the long strip structure and are located between adjacent accommodating spaces. They are used to locally break the fibers on the seed strip, thereby dividing the long strip structure into several seed strips of equal length.

[0021] The present invention also provides a sowing device for identifying disease resistance of rice varieties, which is prepared based on the above-mentioned preparation process of a sowing device for identifying disease resistance of rice varieties, and includes a long strip structure and a seedling tray; the long strip structure is arranged on the seedling tray;

[0022] The strip structure has several depressions symmetrically arranged along its two long sides, and the depressions are evenly spaced. The strip structure has several grooves symmetrically arranged on its surface near the depressions. The grooves are evenly spaced. The strip structure is symmetrically bent along its width, and the depressions on one side of the bent opening form an interlaced space, and the grooves form a water channel.

[0023] An accommodating space is formed below the interpenetrating space by blowing, and the interpenetrating space is connected to the accommodating space; the bent long strip structure is bonded and connected at parts other than the interpenetrating space and the accommodating space, and a plurality of dotted scratches are provided on the surface of the long strip structure along the width direction.

[0024] In a preferred embodiment of the present invention, a plurality of seedling raising holes are provided on the surface of the seedling raising tray, and the plurality of seedling raising holes are distributed in a linear array and correspond one-to-one to the accommodating spaces.

[0025] In a preferred embodiment of the present invention, both ends of the water flow channel are connected to the adjacent accommodating spaces for passing water between the adjacent accommodating spaces. The water flow channel is provided on the upper surface of the seedling tray. The present invention solves the defects existing in the background art and has the following beneficial effects:

[0026] (1) The present invention provides a preparation process for a rice variety disease resistance identification and sowing device, wherein a seed belt having an interlaced space, a water flow channel and a receiving space is prepared by melt-blowing technology. The interlaced space receives rice seeds, reduces the bouncing and rolling of rice seeds, makes the positioning of rice seeds more accurate, avoids confusion of multiple varieties, and improves the work efficiency of later disease investigations. In addition, the water flow channel connects the receiving space to keep the water level consistent.

[0027] (2) The present invention provides interleaving spaces and accommodating spaces, which are arranged in an array. The openings of the interleaving spaces are used to receive rice seeds at fixed points, and the problems of bouncing and rolling of rice seeds are reduced during the seeding process. The variety and quantity of rice seeds entering the accommodating spaces can be accurately controlled, solving the problems in the prior art of difficulty in correcting and adjusting misplaced seeds during the seeding process, and the problem of easy confusion when multiple varieties are seeded at the same time.

[0028] (3) The present invention is provided with a holding space and a water flow channel. When the rice seeds are in the holding space, water only needs to be added from one end of the water flow channel when the rice seeds are replenished with water multiple times. The water enters different holding spaces along the water flow channel, so that the water levels in the holding spaces on the same seed belt are level, reducing the drift of the seeds in the water and making the growth environment of multiple rice seeds consistent, which is beneficial to the identification and comparison of the disease resistance of rice varieties.

[0029] (4) The present invention utilizes dotted line scratches to locally break the fibers between the seed strips, making it easier to separate the seed strips, facilitating the positioning of adjacent seed strips, and further improving positioning accuracy.

[0030] (5) The present invention places the seeds in strips on the seedling tray, and each receiving space corresponds to a seedling hole, which is arranged more regularly and is conducive to the identification and observation of multiple varieties of rice seeds. The through holes opened on the surface of the receiving space are used for the rice seeds to exchange substances with the external soil or water, which can facilitate the growth of the rice seedling root system.

[0031] (6) After the rice seeds are put into the accommodation space, the present invention bonds the portion between the interlaced space and the accommodation space and cuts off the interlaced space. This can reduce the volume of the seed belt when storing the seed belt, facilitates storage, and eliminates the worry that the rice seeds will fall out of the seed belt.

[0043] like Figure 1As shown, the present invention provides a preparation process for a rice variety disease resistance identification and sowing device, comprising the following steps:

[0044] S1. A long strip structure 2 is formed by stacking using meltblowing technology. A plurality of depressions 4 are symmetrically formed along the two long sides of the surface of the long strip structure 2, and grooves 5 are formed inside the depressions 4;

[0045] S2. Bend the strip structure 2 along the center line in the width direction. The combination of the depressions 4 forms an interpenetrating space 6. The combination of the grooves 5 forms a water flow channel 7. A receiving space 8 is reserved below the interpenetrating space 6. The bent strip structure 2 is bonded.

[0046] S3. Insert a catheter into the accommodating space 8 from above the interpenetrating space 6, and blow air into the accommodating space 8 through the catheter. After the accommodating space 8 swells in all directions under the action of the air, remove the catheter.

[0047] S4. Sprinkle the wheat seeds into the accommodating space 8, glue the connecting position between the interlaced space 6 and the accommodating space 8, and cut off the excess parts below the interlaced space 6 and the water channel 7, and then divide the long strip structure 2 into multiple seed belts 1, and arrange them on the seedling tray 3 in sequence.

[0048] In the present invention, the preparation of the long strip structure 2 and the installation of rice seeds are in a certain order, which makes it unnecessary to press the rice seeds in the process of combining them with the seed belt 1. The rice seeds only need to be sprinkled on the surface of the seed plate to avoid the situation where the seeds are broken due to pressing. Due to the pre-prepared depression 4, the distance between the seeds is determined before assembly, which reduces the difficulty of positioning and ensures accurate positioning.

[0049] The seed tape 1 in the present invention is formed by dividing a long strip structure 2 and is made of a polymer prepared by meltblowing technology. The polymer is a degradable material. In the present invention, the degradable material is preferably polylactide. Polylactide is obtained by synthesizing lactic acid and polymerizing starch extracted from annual plants such as corn, wheat, and wood rose as the initial raw material.

[0050] On the one hand, the polylactide material has a certain plasticity, which is beneficial to improving the fracture resistance of the sowing belt and meets the requirements for the formation of depressions 4, grooves 5 or accommodating spaces 8. On the other hand, after contacting soil or water, this material will decompose into carbon dioxide and water in one month, and under the action of sunlight photosynthesis, it will become the starting material of starch, which is pollution-free to the environment and has little effect on the germination of rice seeds.

[0051] In this embodiment, the groove 5 is semi-cylindrical in shape and is located between two adjacent recesses 4; the water channel 7 is located at the upper part of the accommodating space 8 for connecting the two adjacent accommodating spaces 8; the accommodating space 8 is trapezoidal, rectangular or oval in shape for accommodating rice seeds.

[0052] The positions of the depression 4 and the groove 5 are staggered, and the depression 4 is located directly above the accommodating space 8. The water flow channel 7 formed by the docking combination of the grooves 5 on both sides connects the two adjacent accommodating spaces 8. When replenishing water to the rice seeds multiple times, it is only necessary to replenish water from one end of the water flow channel 7. The water enters different accommodating spaces 8 along the water flow channel 7, so that the water levels in the accommodating spaces 8 on the same seed belt 1 are level, reducing the drift of seeds in the water and making the growth environment of multiple rice seeds consistent, which is conducive to the identification and comparison of disease resistance of rice varieties.

[0053] like Figure 3 As shown, the interleaving space 6 is semi-elliptical, semi-circular or semi-oval, and a slope is provided at the bottom of the interleaving space 6, the slopes are arranged opposite to each other, and the slopes are inclined toward the middle; the rice seeds first fall into the interleaving space 6, and then fall from the interleaving space 6 into the accommodating space 8; the excess part that is cut off refers to the part below the water flow channel 7 and between adjacent accommodating spaces 8.

[0054] The shape of the interlaced space 6 is convenient for receiving the falling rice seeds. The slopes at the bottom of the interlaced space 6 are set opposite to each other, and the downslope is located in the middle. After the rice seeds fall on the interlaced space 6, they slide freely along the slope into the accommodating space 8 without the need for positioning. In addition, the bouncing and rolling problems of the rice seeds are reduced during the seeding process, and the precise positioning of the final product of the rice seed belt 1 is not affected. This solves the problem of difficulty in correcting and adjusting misplaced seeds during the seeding process in the prior art.

[0055] The portion between the interpenetrating space 6 and the accommodating space 8 is bonded together, and the interpenetrating space 6 is cut off, so that the volume of the seed belt 1 can be reduced when the seed belt 1 is stored, which is conducive to storage, and there is no need to worry about rice seeds falling out of the seed belt 1.

[0056] In this embodiment, a number of dotted scratches are cut along the width direction of the long strip structure 2. The dotted scratches are evenly distributed along the length direction of the long strip structure 2 and are located between adjacent accommodating spaces 8. They are used to locally break the fibers on the seed strip 1, thereby dividing the long strip structure 2 into several seed strips 1 of equal length.

[0057] A laser punch can be used to create dotted lines on the surface of the strip structure 2, or other forming methods can be used. The dotted lines can be used to partially break the fibers between the seed strips 1, making it easier to separate the seed strips 1, facilitating the positioning of adjacent seed strips 1, and further improving positioning accuracy.

[0058] like Figure 2 As shown, a sowing device for identifying disease resistance of rice varieties is prepared based on the above-mentioned preparation process of a sowing device for identifying disease resistance of rice varieties, and includes a long strip structure 2 and a seedling tray 3; the long strip structure 2 is arranged on the seedling tray 3;

[0059] Several depressions 4 are symmetrically arranged along the two long sides of the long strip structure 2, and the depressions 4 are evenly spaced. Several grooves 5 are symmetrically arranged on the surface of the long strip structure 2 near the depressions 4. The grooves 5 are evenly spaced. The long strip structure 2 is symmetrically bent along the width direction, and the depressions 4 on one side of the bent opening are combined to form an interlaced space 6, and the grooves 5 are combined to form a water flow channel 7.

[0060] An accommodating space 8 is formed below the interpenetrating space 6 by blowing, the interpenetrating space 6 is connected to the accommodating space 8, and a plurality of through holes are provided on the surface of the accommodating space 8; the bent long strip structure 2 is bonded together except for the interpenetrating space 6 and the accommodating space 8, and a plurality of dotted scratches are provided on the surface of the long strip structure 2 along the width direction.

[0061] In the present invention, the thickness of the strip structure 2 at the locations of the depression 4, groove 5, and accommodating space 8 is 1.4-1.6 mm, and the thickness of the remaining locations is 1.1-1.3 mm. Here, the strip structure 2 at the locations of the depression 4, groove 5, and accommodating space 8 is thickened to improve the plasticity of the seed tape 1 and ensure the molding of the depression 4, groove 5, and accommodating space 8.

[0062] The through holes formed on the surface of the accommodating space 8 of the present invention are used for material exchange between rice seeds and external soil or water, thereby facilitating the growth of the roots of the rice seedlings.

[0063] like Figure 4 As shown, a plurality of seedling raising holes 9 are provided on the surface of the seedling raising tray 3 , and the plurality of seedling raising holes 9 are distributed in a linear array and correspond one to one with the accommodating spaces 8 .

[0064] In the present invention, the distance between adjacent accommodating spaces 8 is 10-12 cm, and the distance between the dotted line marks and adjacent accommodating spaces 8 is 5-6 cm. In the present invention, the spacing between each row of seedling holes 9 is 10-12 cm. The present invention utilizes the row and column spacing of the seedling holes 9 to ensure precise seed positioning and achieve the highest yield.

[0065] In this embodiment, both ends of the water flow channel 7 are connected to adjacent accommodating spaces 8 for passing water between adjacent accommodating spaces 8 , and the water flow channel 7 is provided on the upper surface of the seedling tray 3 .

[0066] The seeding device used in the present invention includes: several seeding trays, several seeding channels, a conveyor belt and an image sensor; the several seeding trays are used to load rice seeds of different varieties; the several seeding channels are connected to the seeding trays and are used to sow rice seeds of different varieties; a clamp that can clamp the seed belt is provided on the conveyor belt, so that the conveyor belt can move with the seed belt, and the interlaced space is facing upward; the image sensor is provided on the outlet end of the seeding channel, and the outlet end of the seeding channel is located above the interlaced space of the seed belt, and the image sensor is used to monitor the interlaced space: when the interlaced space moves to the lower part of the outlet end of the seeding channel, the seeding channel is controlled to open, and the rice seeds fall to achieve fixed-point seeding; the seeding trays are arranged in an array, and the conveyor belt passes under the seeding channel. The seeding trays are seeded one by one in sequence to distinguish the distribution positions of rice seeds of different varieties. For example, after the first seeding tray is seeded five times, it stops seeding, and the second seeding tray starts seeding, and it is also seeded five times, and so on. During this process, the conveyor belt does not stop. The above-mentioned seeding device, combined with the special design of the seed belt, can accurately control the variety and quantity of rice seeds entering the accommodating space, solving the problem of confusion that easily occurs when seeding multiple varieties.

[0067] Based on the above preparation process and seed tape 1, the present invention provides a forming device for the seed tape 1. The forming device comprises: a primary forming component, a bending component, a gluing component, a blowing component and a shearing component.

[0068] like Figure 5 As shown, the primary forming assembly includes several die heads arranged in an array, and a forming belt 10 positioned directly below the die heads. The forming belt 10 has several forming bumps 11 on both edges, and several forming ridges 11 on its surface. The ridges 11 are positioned inside the forming bumps 11 and are staggered with each other. A spinneret is formed below the die heads. The forming bumps 11 are the same shape and size as the depressions 4, and the forming ridges 11 are the same shape and size as the grooves 5.

[0069] In the present invention, the nozzle sprays the polymer onto the surface of the forming belt 10, and the polymer sprayed by the nozzle radiates the width of the forming belt 10. High-speed hot air is used to draw the fine stream of polymer melt extruded from the die spinneret, thereby forming ultrafine fibers that condense on the forming belt 10 and form a long strip structure 2 through self-bonding.

[0070] The bending assembly in the present invention includes: a first splint and a second splint connected by a rotating shaft; the first splint and the second splint are both provided with a plurality of forming grooves 5 and a plurality of forming concave strips on an edge away from the rotating shaft, and the forming grooves 5 are consistent in shape, size and arrangement with the depressions 4 of the long strip structure 2, and the forming concave strips are consistent in shape, size and arrangement with the grooves 5 of the long strip structure 2.

[0071] The gluing assembly of the present invention is a movable gluing head, which is arranged directly above the first and second clamping plates. The position of the gluing head corresponds to the gluing position. The gluing head adopts an array gluing method, and the gluing position excludes the depression 4, the groove 5, and the receiving space 8.

[0072] The present invention transfers the long strip structure 2 prepared by the above-mentioned primary forming assembly to the first plywood and the second plywood, and ensures that the depressions 4 and grooves 5 on the long strip structure 2 correspond one to one with the forming grooves 5 and the forming concave strips; uses a gluing head to apply glue to the surface of the long strip structure 2, and rotates the rotating shaft so that the left pressure plate and the right pressure plate overlap, thereby achieving gluing, bending and shaping.

[0073] It should be noted that the coating used in the present invention uses glutinous rice glue, whose main ingredients are edible glutinous rice starch, edible potassium sorbate, edible white vinegar, and water. The glutinous rice glue in the present invention is food-grade and eliminates concerns about rice seed safety and environmental pollution. The glutinous rice glue in the present invention does not come into direct contact with the rice seeds; it only serves to shape the depressions 4 and water channels 7, thus preventing any impact on the rice seeds.

[0074] In order to ensure the stability of the interpenetrating space 6 and the water flow channel 7 in the long strip structure 2, it is necessary to reinforce the joints between the two recesses 4 and the two grooves 5. The present invention can use ultrasonic technology or manual sewing to reinforce the joints.

[0075] The blowing assembly in the present invention includes: a blower, a telescopic bracket, and a plurality of conduits arranged at the bottom of the telescopic bracket; the blower is connected to the conduits through an air pipe; the telescopic bracket is used to insert the guide rod into the accommodating space 8 through the interlaced space 6, and blow air into the accommodating space 8 through the blower; the accommodating space 8 is inflated and formed under the action of the gas.

[0076] The shearing component in the present invention is used to shear the interlacing space 6. The shearing timing is: after the rice seeds pass through the interlacing space 6 and enter the containing space 8, and after the part between the interlacing space 6 and the containing space 8 is bonded together; the shearing position is between the interlacing space 6 and the containing space 8.

[0077] The present invention also uses a bonding device, which includes a plurality of ultrasonic bonding heads for bonding the area between the penetration space 6 and the accommodating space 8.

[0078] This embodiment also provides a method for using the seed tape 1 forming device, comprising the following steps:

[0079] A1. Forming of the long strip structure 2: The die head sprays the meltblown material onto the forming belt 10 having the forming protrusions 11 and the forming protrusions 11 on both edges in the longitudinal direction. The meltblown material sprayed by the die head radiates the width of the forming belt 10 to form the long strip structure 2.

[0080] A2. Pulling and alignment: Clamp the strip structure 2 with a clamp, pull it and align it to the middle position between the first and second plywood plates, and ensure that the depressions 4 and grooves 5 on the strip structure 2 correspond to the molded grooves 5 and the molded ridges 11 respectively;

[0081] A3. Positioning Gluing: Glue is applied to the surface of the long strip structure 2 using a glue applying device. The glue application position does not involve the positions of the depression 4, the groove 5, and the accommodation space 8. Glue application facilitates the fixation of the long strip structure 2 after bending, and the formation of the interlaced space 6, the water flow channel 7, and the accommodation space 8.

[0082] A4. Bending: The first and second splints are pressed against each other by the rotating shaft, and the long strip structure 2 can be cut to a fixed length using a tool;

[0083] A5. Formation of the accommodating space 8: Insert the catheter from above the interpenetrating space 6 toward the accommodating space 8, then use the blowing assembly to blow air into the accommodating space 8 to bulge the accommodating space 8 into shape, and then remove the catheter;

[0084] A6. The rice seeds are evenly scattered on the interlaced space 6 by the seed-dispensing device, and slide into the accommodating space 8 via the two slopes. The rice seeds enter the accommodating space 8;

[0085] A7. Sealing the accommodating space 8: Using an adhesive device, the upper opening of the accommodating space 8 is bonded;

[0086] A8. Use a shearing device to cut off the excess parts and interlaced spaces 6 below the water flow channel 7 and between adjacent accommodating spaces 8, and coil them for storage.

[0087] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the content of the specification and must be determined according to the scope of the claims.
