Description

Technical Field

[0001] The present invention relates to the technical field of seedling trays, and specifically to a culture tray for paddy rice seedling breeding. Background Art

[0002] During the process of paddy rice seedling breeding, the use of culture trays is crucial. Traditional culture trays often only have a single seedling raising function and cannot meet the various requirements for the seedling growth environment in modern agricultural production. For example, traditional culture trays usually only provide soil or substrates to support the growth of seedlings, but they are insufficient in aspects such as water management, air permeability, and nutrient solution supply.

[0003] Firstly, in terms of water management, traditional culture trays often provide water by directly watering or soaking. This method not only makes it difficult to precisely control the amount of water but also may cause the roots of the seedlings to be overly wet, affecting the growth and development of the seedlings. Secondly, in terms of air permeability, the bottom of traditional culture trays is usually closed and lacks necessary ventilation structures, resulting in poor respiration of the roots of the seedlings and affecting the growth rate and quality of the seedlings. Finally, in terms of nutrient solution supply, traditional culture trays usually do not have a dedicated nutrient solution storage and supply system and require manual watering at regular intervals. This is not only cumbersome to operate but also difficult to ensure the uniform supply of the nutrient solution.

[0004] Therefore, in order to overcome the deficiencies of traditional culture trays and improve the effect and efficiency of paddy rice seedling breeding, the present invention proposes a culture tray for paddy rice seedling breeding. Summary of the Invention

[0005] The purpose of the present invention is to provide a culture tray for paddy rice seedling breeding to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A culture tray for paddy rice seedling breeding, including a seedling raising tray. A through hole is opened at the bottom of the seedling raising tray, and retaining plates are fixed at both ends of the through hole. Ventilation holes one are opened on the surface of the retaining plates. Ventilation holes two are opened on the top surface of the bottom plate of the seedling raising tray, and the ventilation holes two are communicated with the through hole. A liquid storage tank is opened on the top surface of the seedling raising tray for storing nutrient solution. Seepage holes are opened on the side wall of the liquid storage tank close to the tank body of the seedling raising tray. A sealing plate is fixed inside the liquid storage tank. A backing plate is fixed to the bottom surface of the seedling raising tray, and the thickness of the backing plate is equal to the distance from the top surface of the seedling raising tray to the top surface of the sealing plate.

[0007] Preferably, a plurality of ventilation holes one are provided, and the plurality of ventilation holes one are arranged and distributed at equal distances and of equal size along the long side of the retaining plate. Clear water is stored inside the through hole, and the water surface of the clear water is below the bottom surface of the ventilation holes one.

[0008] Preferably, an installation groove is formed on the top surface of the seedling tray, a slot is formed on the top surface of the enclosing plate, a positioning groove is formed on the bottom surface of the slot, a baffle is inserted into the installation groove, the bottom end of the baffle is inserted into the positioning groove, rubber strips are fixed on both sides of the bottom end of the baffle, the rubber strips are clamped between the baffle and the positioning groove to generate elastic deformation, and the bottom end of the baffle blocks the air holes I.

[0009] Preferably, after the bottom end of the baffle is inserted into the positioning groove, there is a space between the top surface of the baffle and the top surface of the seedling tray. Two finger grooves are formed on the top surface of the baffle, and two groups of reserved grooves are formed on the top surface of the seedling tray. The finger grooves are directly below the reserved grooves.

[0010] Preferably, the liquid storage tank is an annular groove, the height of the liquid storage tank is equal to the height of the tank body of the seedling tray, the sealing plate is in an annular plate structure, a liquid injection port is formed on the surface of the sealing plate, the liquid injection port is a "T"-shaped round hole, and a sealing head is inserted into the liquid injection port. The sealing head is in a "T"-shaped cylindrical structure.

[0011] Preferably, internal threads are provided in the groove of the liquid injection port, external threads are provided on the surface of the sealing head, the external threads and the internal threads are in threaded connection, and a handle is fixed on the top surface of the sealing head. The handle is in a "cross"-shaped plate structure.

[0012] Preferably, there are two groups of seepage holes, and the two groups of seepage holes are symmetrically distributed with respect to the tank body of the seedling tray. The seepage holes communicate the liquid storage tank and the tank body of the seedling tray.

[0013] Preferably, a notch is formed on the top surface of the seedling tray, the bottom surface of the notch and the top surface of the sealing plate are coplanar, and a hand-twist long handle screw is screwed on the bottom surface of the notch. The bottom end of the hand-twist long handle screw blocks the seepage holes.

[0014] Preferably, an installation opening is formed on the top surface of the bottom plate of the seedling tray. The installation opening is an inverted "convex"-shaped round hole, and a water-absorbing cotton core is inserted and fixed in the installation opening. The water-absorbing cotton core is in a "T"-shaped cylindrical shape, and the bottom end of the water-absorbing cotton core abuts above the bottom surface of the through hole.

[0015] Preferably, the cushion plate is in an annular plate structure. There are multiple seedling trays. After two adjacent seedling trays are stacked, the cushion plate at the bottom of one seedling tray is inserted into the baffle at the top of the other seedling tray.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The culture tray for paddy rice seedling breeding proposed by the present invention realizes the storage and precise management of clear water by opening a through-hole at the bottom of the culture tray and installing a retaining plate. The clear water falls into the through-hole through the second ventilation hole, which not only ensures the water required for the growth of the seedlings but also avoids the problem of over-wet roots. At the same time, the addition of the absorbent cotton core enables the water to be continuously and evenly supplied to the seedlings, improving the accuracy and efficiency of water management. The first ventilation hole opened on the surface of the retaining plate constitutes a convection channel, enabling the gas emitted from the second ventilation hole to be smoothly discharged, ensuring good air permeability of the roots of the seedlings. This design not only facilitates the growth and development of the seedlings but also effectively prevents the occurrence of diseases.

[0018] The design of the liquid storage tank and seepage holes opened at the top of the culture tray enables the nutrient solution to be automatically supplied to the seedlings as needed. By adjusting the position of the hand-twisted long handle screw, the supply amount and supply time of the nutrient solution can be controlled, realizing the precise management and efficient utilization of the nutrient solution.

[0019] The backing plate fixed at the bottom of the culture tray not only increases the stability of the culture tray but also enables multiple culture trays to be neatly arranged when stacked. The plug-in design of the backing plate and the first ventilation hole further ensures the firmness and stability during stacking, avoiding damage or safety accidents caused by unstable stacking.

Specific implementation manner

[0032] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a cultivation tray for paddy rice seedling breeding, including a seedling tray 1. A through hole 2 is opened at the bottom of the seedling tray 1. Enclosing plates 3 are fixed at both ends of the through hole 2. Air vents 1 4 are opened on the surface of the enclosing plates 3. There are multiple air vents 1 4, and the multiple air vents 1 4 are arranged and distributed at equal distances and of equal size along the long side of the enclosing plate 3. Clear water is stored inside the through hole 2, and the water surface of the clear water is below the bottom surface of the air vents 1 4. An air vent 2 5 is opened on the top surface of the bottom plate of the seedling tray 1, and the air vent 2 5 communicates with the through hole 2. An installation groove 8 is opened on the top surface of the seedling tray 1. A slot 9 is opened on the top surface of the enclosing plate 3. A positioning groove 10 is opened on the bottom surface of the slot 9. A baffle 24 is inserted inside the installation groove 8, and the bottom end of the baffle 24 is inserted into the positioning groove 10. Rubber strips 13 are fixed on both sides at the bottom end of the baffle 24. The rubber strips 13 are clamped between the baffle 24 and the positioning groove 10 to generate elastic deformation. The bottom end of the baffle 24 blocks the air vents 1 4. After the bottom end of the baffle 24 is inserted into the positioning groove 10, there is a space between the top surface of the baffle 24 and the top surface of the seedling tray 1. Two finger grooves are opened on the top surface of the baffle 24. Two groups of reserved grooves 11 are opened on the top surface of the seedling tray 1, and the finger grooves are directly below the reserved grooves 11.

[0034] In use, the bottom plate structure of the seedling tray 1 is optimized. By opening a through hole 2 in the bottom plate of the seedling tray 1 and installing enclosing plates 3 at both ends of the through hole 2 for blocking, it is realized that the bottom plate of the seedling tray 1 can store clear water. The clear water is directly poured into the trough of the seedling tray 1, and the clear water falls into the through hole 2 through the second ventilation holes 5 for collection. After seedlings are cultivated inside the seedling tray 1, the first ventilation holes 4 on the surfaces of the two enclosing plates 3 form a convection to discharge the gas emitted from the second ventilation holes 5. In this way, the bottom plate of the seedling tray 1 not only realizes the water storage function but also meets the ventilation function for the bottom of the vegetation. And a water-absorbing cotton core 7 is installed on the bottom plate of the seedling tray 1. After the water-absorbing cotton core 7 adsorbs the clear water collected inside the through hole 2, it transfers it to the vegetation inside the seedling tray 1. In this way, the seedling tray 1 also has an irrigation function, that is, the bottom plate of the seedling tray 1 serves three purposes. When the seedling tray 1 needs to be turned over, in order to prevent the clear water inside the through hole 2 from splashing out through the first ventilation holes 4, the baffle 24 is pushed downward. After the bottom end of the baffle 24 is inserted into the positioning groove 10, the blocking of multiple first ventilation holes 4 is realized. When the first ventilation holes 4 need to be ventilated again, two fingers are respectively inserted into the two reserved grooves 11, and then the fingers move downward until the two fingers hold the two finger grooves on the top surface of the baffle 24, and then the baffle 24 is lifted. After the bottom end of the baffle 24 is pulled out of the slot 9 and retracted into the installation groove 8, the first ventilation holes 4 are used for ventilation.

[0035] A liquid storage tank 14 is opened on the top surface of the seedling tray 1 for storing nutrient solution. A seepage hole 20 is opened on the side wall of the liquid storage tank 14 close to the trough of the seedling tray 1. A sealing plate 15 is fixed inside the liquid storage tank 14. The liquid storage tank 14 is an annular groove, and the height of the liquid storage tank 14 is equal to the height of the trough of the seedling tray 1. The sealing plate 15 is in an annular plate-like structure. A liquid injection port 16 is opened on the surface of the sealing plate 15. The liquid injection port 16 is a "T"-shaped round hole. A sealing head 17 is inserted into the inside of the liquid injection port 16. The sealing head 17 is in a "T"-shaped cylindrical structure. Internal threads are provided in the groove of the liquid injection port 16, and external threads are provided on the surface of the sealing head 17. The external threads and the internal threads are in threaded connection. A handle 18 is fixed on the top surface of the sealing head 17. The handle 18 is in a "cross"-shaped plate-like structure. There are two groups of seepage holes 20, and the two groups of seepage holes 20 are symmetrically distributed with respect to the trough of the seedling tray 1. The seepage holes 20 communicate the liquid storage tank 14 and the trough of the seedling tray 1. A notch 21 is opened on the top surface of the seedling tray 1. The bottom surface of the notch 21 and the top surface of the sealing plate 15 are coplanar. A hand-twist long handle screw 22 is screwed on the bottom surface of the notch 21, and the bottom end of the hand-twist long handle screw 22 blocks the seepage hole 20.

[0036] In use, pinch the handle 18 by hand and turn the sealing head 17 to remove it from the liquid injection port 16. Inject the nutrient solution required for paddy rice seedling breeding into the liquid storage tank 14 through the liquid injection port 16, and then screw the sealing head 17 back to block the liquid injection port 16. When it is necessary to inject the nutrient solution inside the liquid storage tank 14 into the tank body of the seedling tray 1, turn the hand-twist long handle screw 22 upward. After the hand-twist long handle screw 22 is turned to above the seepage hole 20, the nutrient solution inside the liquid storage tank 14 is injected into the tank body of the seedling tray 1 through the seepage hole 20, and the hand-twist long handle screw 22 is turned back to block the seepage hole 20 to achieve the interception of the nutrient solution.

[0037] A backing plate 19 is fixed to the bottom surface of the seedling tray 1. The thickness of the backing plate 19 is equal to the distance from the top surface of the seedling tray 1 to the top surface of the sealing plate 15. The backing plate 19 is in an annular plate structure. There are multiple seedling trays 1. After two adjacent seedling trays 1 are stacked, the backing plate 19 at the bottom of one seedling tray 1 is inserted into the baffle 24 at the top of the other seedling tray 1. In use, when multiple seedling trays 1 are stacked, through the insertion of the backing plate 19 and the air vent 4, it is ensured that multiple seedling trays 1 are neatly stacked; picking grooves 23 are provided on both sides of the seedling tray 1 for fingers to pick and apply force when taking the seedling tray 1.

[0038] The usage process of the paddy rice seedling breeding and cultivation tray is as follows: Install the water-absorbing cotton core 7 on the bottom plate of the seedling tray 1 to ensure that the water-absorbing cotton core 7 can cover the through-hole 2 area to absorb and transfer water. Open the sealing head 17 and inject an appropriate amount of nutrient solution for paddy rice seedling breeding into the liquid storage tank 14 through the liquid injection port 16. After completion, tighten the sealing head 17 to ensure sealing. Sow paddy rice seedling seeds evenly in the tank body of the seedling tray 1. Gently cover a thin layer of soil or substrate to cover the seeds. Add clear water into the tank body of the seedling tray 1, and the clear water will flow into the through-hole 2 through the air vent 5 and be stored. Pay attention to controlling the amount of water added so that the liquid level of the clear water is below the bottom surface of the air vent 4. Push the baffle 24 downward so that its bottom end is inserted into the positioning groove 10 to close the air vent 4. Ensure that the baffle 24 is firmly installed to prevent loosening during handling. Regularly check the growth of the seedlings and adjust the supply of water and nutrient solution as needed. If ventilation is required, the baffle 24 can be opened according to the method described above. When it is necessary to supplement the nutrient solution into the tank body of the seedling tray 1, loosen the hand-twist long handle screw 22 so that the nutrient solution in the liquid storage tank 14 flows into the tank body through the seepage hole 20. Adjust the supply amount and frequency of the nutrient solution according to the growth of the seedlings. After completion, tighten the hand-twist long handle screw 22 to close the seepage hole 20. When the seedlings grow to a certain stage and meet the transplanting requirements, harvest. After harvesting, clean the seedling tray 1 to remove the remaining soil and nutrient solution. Dry the seedling tray 1 for storage or reuse. Stack multiple seedling trays 1 and use the insertion structure of the backing plate 19 and the air vent 4 to ensure neat stacking. If long-term storage is required, an appropriate amount of preservative or rust inhibitor can be applied inside and outside the seedling tray 1 before stacking. Mark the stored seedling trays 1 and record their usage and the planned time for the next use.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
