Description

Technical Field

[0001] This application relates to the field of rice breeding technology, and in particular to a germination and seedling raising device for rice breeding. Background Technology

[0002] Rice seedling raising for germination is a technique that uses artificially created suitable hydrothermal conditions before sowing to promote concentrated germination of rice seeds. This technique can significantly improve the germination rate and germination potential of seeds, shorten the seedling period, and increase the seedling survival rate, thereby promoting the growth and yield of rice. The specific steps of seedling raising for germination include seed selection, seed soaking and disinfection, preheating and water absorption, and germination.

[0003] During the preparation stage, soil needs to be manually filled into seedling trays or containers, and each seed needs to be carefully buried at an appropriate depth. This process is not only time-consuming and laborious, but also prone to inconsistent seed sowing depths due to differences in the skill level and attention to detail of the operators, which in turn affects the germination rate and the uniformity of the seedlings. Moreover, since traditional methods lack effective organization and management systems, whenever we want to check the growth of a specific area or individual seedling, we often need to manually move multiple seedling trays or change the environmental settings. In order to observe the development of the seedling root system more closely, it may be necessary to lift the seedling trays one by one. This process not only consumes a lot of time, but also easily causes physical damage to the tender seedlings.

[0004] Therefore, the traditional seedling raising methods mentioned above often require manual labor, which is cumbersome and inefficient. Moreover, in traditional methods, checking the growth of each rice seedling may require moving multiple containers or changing environmental settings, which is not only time-consuming but also easily damages the seedlings. A rice breeding germination and seedling raising device can be designed. The sliding design allows the placement frame to slide easily within the installation frame. It is also equipped with components such as pull plates and snap-fit ​​columns, which makes it convenient for users to quickly fold up or disassemble the seedling rack, greatly improving the ease of operation. The snap-fit ​​groove design allows multiple seedling racks to be easily connected together or separated for inspection, making it easy to manage and observe the growth status of each group of rice seedlings. Summary of the Invention

[0005] In order to overcome the shortcomings of traditional seedling raising methods, which often require manual labor, are cumbersome and inefficient, and require checking the growth of each rice seedling, which may involve moving multiple containers or changing environmental settings, which is not only time-consuming but also easily damages the seedlings, this application provides a rice breeding germination and seedling raising device.

[0006] The technical solution is as follows: A rice seedling germination and raising device includes an installation frame, a placement frame, sliders, an installation rack, a seedling rack, a connecting plate, a fastening groove, a movable plate, and fastening columns. Multiple placement frames are installed sequentially from top to bottom inside the installation frame. Sliders that slide and connect to the installation frame are installed at the rear ends of both sides of the placement frame. Multiple seedling racks for placing rice seedlings are fastened inside the placement frame. Fastening grooves for connecting or separating multiple seedling racks are opened on the side surface of the seedling racks. A connecting plate is installed on the side of the seedling rack away from the fastening groove. Two sets of fastening columns are symmetrically arranged inside the seedling rack near the connecting plate for unfolding the seedling rack to plant multiple rice seedlings together or separately. A movable plate is fixedly connected to the front end of the fastening column. An installation frame for quickly retracting or disassembling the seedling rack is fixedly connected to the upper end of the seedling rack.

[0007] Furthermore, a pull plate is fixedly connected to the center of the front end of the placement frame, and a placement cavity is opened at the rear end of the placement frame near the corner.

[0008] Furthermore, a cabinet door is installed at the front end of the mounting frame, a hinge groove is provided between the cabinet door and the mounting frame, a handle is installed on the surface of the cabinet door near the corner, and a control panel is installed at the center of the side surface of the mounting frame.

[0009] Furthermore, a water tank is installed at the lower end of the mounting frame, and a connecting pipe connected to the water tank is installed at the lower center of the side of the mounting frame away from the control panel.

[0010] Furthermore, a water pump is installed at the end of the connecting pipe away from the water tank, and a connecting pipe is vertically installed at the top of the water pump.

[0011] Furthermore, a spray pipe located at the top of the mounting frame is installed sequentially from top to bottom on the side of the connecting pipe near the mounting frame, and multiple sets of mist outlets are linearly opened on the surface of the spray pipe.

[0012] Furthermore, a fixing bracket is installed at the lower end of the water pump and is fixedly connected to the mounting frame. A constant temperature module is provided at the center of the rear surface of the mounting frame, penetrating the mounting frame.

[0013] The beneficial effects include a slider design that allows the placement frame to slide smoothly within the installation frame, and the inclusion of pull plates and snap-fit ​​columns, making the folding and disassembly of the seedling rack quick and easy. This not only saves a significant amount of manpower and time but also improves overall work efficiency. The snap-fit ​​grooves on the side surface of the seedling rack allow multiple sets of seedling racks to be easily connected together or disassembled for inspection, facilitating researchers to check the growth of each rice seedling at any time without moving multiple containers or significantly altering the environmental settings, thus reducing potential damage to the seedlings. The water tank, water pump, connecting pipes, and spray pipes provide a uniform water supply for the seedlings, ensuring that each seedling receives suitable humidity conditions, which helps improve seed germination rate and healthy seedling growth. The constant temperature module helps maintain a stable seedling environment temperature, which is crucial for promoting seed germination and healthy seedling growth, and also helps reduce the occurrence of diseases caused by temperature fluctuations. The multi-layer placement frame design effectively increases the number of seedlings per unit area, greatly improving space utilization efficiency and facilitating large-scale experiments and research.

[0020] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Among the currently discovered feasible technologies, the following are described:

[0022] Rice seedling germination technology is a technique that artificially creates suitable hydrothermal conditions before sowing to promote concentrated germination of rice seeds. This technology can significantly improve seed germination rate and vigor, shorten the seedling period, and increase seedling survival rate, thereby promoting rice growth and ultimately increasing yield. The first step is to select healthy, plump, and disease-free high-quality rice seeds. This step is crucial for ensuring uniform germination and strong seedlings. Methods such as winnowing, sieving, or brine flotation are typically used to remove shriveled grains and impurities. To eliminate any pathogens that may be carried on the seed surface and to activate internal seed life activities, the selected seeds need to be soaked in water for a period of time, generally 24 to 48 hours. During this period, an appropriate amount of disinfectant, such as potassium permanganate solution, can be added for disinfection. Furthermore, proper stirring helps ensure that each seed fully absorbs water. After soaking and disinfection, the seeds are removed and drained, then placed in a warm environment (temperature controlled at around 30-35℃) for preheating treatment. This allows the seeds to further absorb water and prepare for the germination stage. This step helps break seed dormancy. The preheated seeds are placed in an ideal environment with constant humidity and temperature, such as the aforementioned germination and seedling raising device. The temperature is usually maintained between 28-32℃ and the relative humidity is kept above 90%. Under these conditions, the seeds begin to germinate rapidly, forming roots and buds. The condition of the seeds is checked regularly, and the temperature and humidity are adjusted according to the actual situation to ensure the best germination effect. Throughout the process, the use of modern germination and seedling raising devices can more accurately control environmental parameters such as temperature, humidity and light, providing a more stable and suitable growth condition, which greatly improves work efficiency and success rate.

[0023] Traditional rice seedling cultivation methods typically rely on manual labor, a process that is not only tedious and complex but also extremely inefficient. From seed selection, soaking and disinfection, germination, to seedling cultivation, each step requires a significant amount of manpower and time. In traditional methods, monitoring the growth of each rice seedling is particularly time-consuming. Due to a lack of effective organizational and management tools, checking the growth of a specific area or individual seedling often requires manually moving multiple seedling containers. This not only wastes valuable time but also frequently damages the delicate seedlings, such as breaking leaves or stems, and may even lead to seedlings being accidentally pulled out of the soil, affecting their normal growth. Furthermore, traditional irrigation methods also have many problems, primarily manifested in uneven water supply. Without a precise irrigation system, it's difficult to maintain optimal humidity levels in each seedling tray. Some areas may suffer from root hypoxia due to excessive moisture, while others may experience drought due to insufficient water. These problems directly impact seed germination rates and seedling health. Uneven water supply can also lead to diseases such as fungal infections, further reducing seedling quality and survival rates. Suitable temperature is crucial for seed germination and seedling growth; however, maintaining a stable temperature environment is challenging in traditional seedling cultivation. Natural temperature fluctuations are significant, especially in areas with large diurnal temperature variations. These changes can inhibit seed germination or cause slow or even stopped seedling growth. Furthermore, extreme temperature changes can induce physiological stress, making seedlings more susceptible to pests and diseases. Traditional rice seedling cultivation methods face significant limitations in operational procedures, growth monitoring, and environmental control. These limitations not only reduce work efficiency and increase labor costs but also negatively impact seedling quality and final yield. Therefore, it is particularly important to adopt more scientific and automated modern seedling cultivation technologies, such as the aforementioned germination and seedling cultivation device.

[0024] To address the problems of cumbersome manual operation, low efficiency, and difficulty in monitoring the growth of each seedling in traditional rice seedling cultivation methods, designing a highly efficient rice breeding and germination device is crucial. This device, through a series of innovative designs, not only significantly improves operational convenience and efficiency but also optimizes the management and observation of seedling growth. First, the device employs a slider design, allowing the placement frame to slide smoothly within the mounting frame. This design allows users to easily pull out or push in the placement frame without effort, significantly improving operational convenience. Furthermore, a pull plate is fixedly connected to the center of the front end of each placement frame, further simplifying the operation process and enabling a single person to efficiently operate multiple seedling racks. Simultaneously, a placement cavity is provided at the rear end of the placement frame near the corner, providing storage space for other auxiliary tools or materials and increasing overall flexibility. Second, the design of the seedling rack is particularly critical for facilitating the management and observation of the growth of each group of rice seedlings. By incorporating locking grooves on the side surface of the seedling rack, quick connection or disassembly of multiple seedling racks is achieved, greatly facilitating researchers to conduct detailed inspections or treatments as needed. A connecting plate is installed on the side of the seedling rack away from the locking groove, and two sets of locking columns for unfolding or retracting are symmetrically installed on the side of the inside near the connecting plate. This allows the seedling rack to be flexibly adjusted according to actual needs, supporting both large-scale planting and easy observation and handling of individual seedlings. Furthermore, considering the need to reduce physical damage to seedlings, the device pays special attention to detail design.

The built-in water tank 15 is located at the bottom of the mounting frame 1, providing a stable water supply for the entire system and ensuring worry-free long-term operation.

[0030] A water pump 10 is installed at the end of the connecting pipe 9 away from the water tank 15. A connecting pipe 11 is vertically installed on the upper end of the water pump 10. The connecting pipe 9 connects the water tank 15 and the water pump 10 to ensure that the water source can be efficiently delivered to the place where it is needed and to support the normal operation of the system.

[0031] A spray pipe 12 located at the top of the placement frame 16 is installed sequentially from top to bottom on the side of the connecting pipe 11 near the mounting frame 1. Multiple sets of mist outlets 13 are linearly opened on the surface of the spray pipe 12. The design of the spray pipe 12 and the mist outlets 13 on its surface realizes uniform humidification of the seedling environment, which is conducive to the healthy growth of seedlings.

[0032] The lower end of the water pump 10 is equipped with a fixing bracket 8 that is fixedly connected to the mounting frame 1.
