Description

Technical Field

[0001] This utility model belongs to the field of wheat seed breeding technology, specifically relating to a vernalization device for wheat seeds. Background Technology

[0002] Vernalization refers to the process by which wheat, after initially encountering low temperatures, gradually transforms the low-temperature signal into a sensitivity to high temperatures, guiding the wheat from dormancy to a growth state. Vernalization plays a crucial role in the normal growth and development of wheat.

[0003] The vernalization process for wheat generally requires specific conditions regarding time, temperature, and light. In terms of time, vernalization takes 30-60 days. After a period of dormancy, wheat begins vernalization as the ambient temperature gradually rises. Vernalization mostly occurs in late autumn and early winter, and by the end of vernalization, the plant's growth point has gradually differentiated. Regarding temperature, wheat vernalization requires a range of -5℃ to 15℃, with the optimal temperature being 3℃ to 5℃. Temperature experiments show that when wheat is exposed to lower temperatures, endogenous hormones are released, initiating vernalization. The lower the temperature during vernalization, the longer the process lasts; therefore, in many regions, wheat undergoes vernalization in winter. Furthermore, sufficient light is crucial for vernalization. The amount of light during vernalization has a significant impact on wheat growth, development, and yield. Weak light intensity results in poor vernalization, and prolonged periods of low light can slow wheat development and affect yield. Generally, approximately 13.5 hours of light per day is sufficient for wheat vernalization.

[0004] Chinese utility model patent application number CN202121224900.6 discloses a wheat vernalization incubator, which can improve the uniformity of low-temperature vernalization treatment of wheat within the incubator, reduce uneven cooling, and improve practicality. It includes an incubator, a movable base, a partition frame, multiple sets of transmission pipes, multiple sets of fixing pipes, multiple sets of air outlets, two sets of support frames, and multiple sets of movable rings. Two sets of doors are provided on the front side wall of the incubator. Both sets of support frames are installed inside the incubator. Multiple sets of movable rings are respectively fitted onto the two sets of support frames. Filter cloth is laid flat at the bottom of the groove. A cooling module is provided at the top of the incubator. The partition frame is installed at the rear top of the incubator and has an air inlet and multiple sets of air outlets. A fan is provided at the air inlet. Multiple sets of transmission pipes are respectively installed at the multiple sets of air outlets and are connected to multiple sets of fixing pipes. Multiple sets of fixing pipes are all installed in the lower half of the incubator, and multiple sets of air outlets are connected to multiple sets of fixing pipes.

[0005] The above-mentioned scheme effectively controls the temperature during the vernalization stage of wheat, ensuring that the temperature conditions meet the requirements for vernalization. However, this scheme also has certain drawbacks. On the one hand, moving the wheat within the incubator increases the complexity of the overall equipment structure, resulting in high costs and large investments. On the other hand, it can only vernalize a single layer of wheat seeds, limiting the number of seeds that can be cultured and leading to low efficiency. Furthermore, the above-mentioned scheme does not effectively control the light conditions, which will also have an adverse effect on the vernalization results of the seeds. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-2 As shown, a vernalization device for wheat seeds includes a box 1 with multiple partitions 5 inside. A door 3 that can be opened and closed is installed at the front end of the box 1. The partitions 5 are removable and installed inside the box 1. Guide rails are installed on both sides of the inner side of the box 1. The partitions 5 can be pulled outward under the action of the guide rails to facilitate the taking and putting of seeds. The door 3 is rotatably installed at the front end of the box 1 by means of a hinge. In order to improve the sealing effect when the door 3 is closed, a sealing strip can be set around the edges of the door 3 or a magnetic attraction can be used to contact the box 1.

[0024] Reflective film 7 is installed on the inner wall of the box 1 and the lower surface of the partition 5. Specifically, the reflective film 7 is fixed to the top wall, side walls, bottom wall and end wall of the box 1 by adhesive. It has the advantages of low reflectivity, low cost and easy installation.

[0025] The inner wall of the box door 3 has supplementary lights 4 installed vertically. The supplementary lights 4 are installed in the middle of the inner wall of the box door 3. In addition, two supplementary lights 4 can be set according to actual needs. The two supplementary lights 4 are symmetrically distributed with respect to the center of the box door 3. This is used when the box body 1 is wide. In this way, when the box door 3 is closed, the light emitted by the supplementary lights 4 can be reflected onto the seed surface of the partition 5 under the action of the reflective film 7. Since the reflective film 7 is not only set on the inner wall of the box body 1, but also pasted under each partition 5, the light can not only directly illuminate some seeds, but also illuminate other seeds through the reflection of the reflective film 7. This ensures that all seeds can receive sufficient light and ensures the uniformity of light, which is beneficial to the cultivation of wheat seeds.

[0026] The door 3 is made of transparent material, specifically transparent glass, so that users can observe the seed cultivation status through the door 3.

[0027] Multiple temperature sensors 2 are installed on the inner wall of the box 1. The temperature sensors 2 are used to monitor the temperature at different locations inside the box 1 in real time. For example, the temperature inside the box 1 can be set to 3℃-5℃, which is the most suitable temperature for wheat vernalization. When the temperature exceeds this range, the temperature sensors 2 can feed back the signal to the controller, thereby performing heating or cooling operations.

[0028] The temperature sensor 2 is installed on the side wall of the box 1 above each partition 5. This arrangement allows for more accurate monitoring of the real-time temperature value inside the box 1.

[0029] With the door 3 closed, a first gap 9 is formed between the front end of the partition 5 and the door 3, and a second gap 10 is formed between the rear end of the partition 5 and the end wall of the box 1. This arrangement is intended to allow cold air to flow through the first gap 9 and the second gap 10 during the cooling process, so as to quickly reduce the temperature inside the box 1.

[0030] The surface of the partition 5 has a plurality of evenly distributed through holes 8. In the actual vernalization process, wheat seeds can be placed on the partition 5 in multiple seed boxes. At this time, hot and cold air can also pass through the through holes 8 to improve the air permeability.

[0031] The device also includes an electrical control box 6 and a cooling module installed at the bottom of the inner cavity of the housing 1. The electrical control box 6 is equipped with a time controller, which is connected to the supplementary light 4 to control the illumination time. The electrical control box 6 is also equipped with a controller connected to the temperature sensor 2 to collect and process the signals fed back by the temperature sensor 2, and to control the cooling module to perform cooling treatment. The structure and principle of the internal electrical components of the electrical control box 6 and the structure and principle of the cooling module are conventional technologies in the prior art, and will not be described in detail here.

[0032] When using this vernalization device for wheat seeds, the wheat seeds are first placed in a culture box or petri dish, and then the culture box or petri dish is placed on the partition 5. The door 3 is closed, and the supplemental light 4 provides the seeds with light conditions for the low-temperature vernalization stage. During the light exposure process, the reflective film 7 ensures that all seeds receive light. The temperature inside the chamber 1 is controlled by a cooling module and a temperature sensor 2 to ensure that the seeds receive good light and temperature conditions. This vernalization device has the advantages of simple structure, low cost, and good vernalization effect.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
