[0002] To improve the yield, disease and pest resistance, and drought tolerance of rice, it is usually necessary to conduct rice seedling cultivation experiments. This involves determining experimental factors such as rice variety, planting density, fertilizer application, and irrigation amount, and designing corresponding control and experimental groups for growth experiments.

[0003] Traditionally, rice seedlings are cultivated in an outdoor field during experimental breeding. This method tends to consume a lot of land resources, and the unpredictable weather in the natural environment makes it difficult to maintain stable growth conditions, which is not conducive to conducting large-scale experiments efficiently. In addition, the need for manual recording of growth data can easily lead to errors.

[0004] Therefore, to address the problems of traditional rice seedling cultivation, which consumes a lot of field resources, makes it difficult to maintain stable growth conditions, and is prone to data errors, a rice cultivation device that can automatically record the growth process can be designed. By integrating water supply and light conditions, stable growth conditions can be achieved, and a monitoring structure can be integrated to monitor and record the rice production process, thereby facilitating the solution of the above problems.

[0021] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] As the staple food for more than half of the world's population, rice's yield, quality, and adaptability to the environment have always been a focus of agricultural research. Experimental seedling cultivation plays a cornerstone role in rice research. Through detailed observation and research on the growth of rice seedlings, researchers can gain a deeper understanding of the response mechanisms of rice to different environmental factors from the initial stage, laying the foundation for subsequent optimization of planting techniques and cultivation of superior varieties. For example, when studying the resistance of rice to diseases and pests, the resistance performance of seedlings to diseases and pests can help researchers screen out varieties with potential resistance genes, and then cultivate new varieties with greater resistance through hybridization, gene editing, and other means, reducing the threat of diseases and pests to rice yield.

[0023] Rice seed germination is a complex physiological process. Under suitable conditions, the cells of the embryo inside the seed begin to divide and elongate actively. During this period, the seed needs to absorb sufficient water to initiate a series of physiological and biochemical reactions, including enzyme activation, decomposition and transformation of stored substances, etc., thereby providing energy and material basis for embryo growth. At the same time, a suitable temperature can ensure that the enzymatic reactions proceed at the optimal rate, promoting the successful completion of seed germination.

[0024] During seedling growth, photosynthesis plays a central role. Chlorophyll in the leaves absorbs light energy and converts carbon dioxide and water into organic matter and oxygen, providing energy and substances for the plant's growth and development. The root system is responsible for absorbing water and mineral nutrients, such as nitrogen, phosphorus, and potassium, from the external environment. These elements are crucial for the construction of seedling cell structure, metabolism, and regulation of physiological functions. In addition, plant hormones also play a key regulatory role at various stages of seedling growth, such as auxin promoting cell elongation and cytokinin promoting cell division.

[0025] Temperature has a significant impact on rice seedling cultivation. During the seed germination stage, a relatively high and stable temperature is required, generally between 25-35℃, to promote rapid water absorption, enhanced enzyme activity, and embryo germination. As the seedlings enter the growth stage, a suitable diurnal temperature range is beneficial to plant growth and development. Maintaining a daytime temperature of 25-28℃ allows for efficient photosynthesis, while a slightly lower nighttime temperature of 18-22℃ helps reduce the consumption of organic matter by respiration and accumulate more photosynthetic products.

[0026] Light provides energy for photosynthesis in rice seedlings. Its intensity, duration, and spectral composition all have a significant impact on seedling growth. In the early stages of seedling cultivation, a relatively weak light intensity is sufficient. As the seedlings grow, the light intensity is gradually increased to a suitable range, generally 300-800 μmol·m⁻²·s⁻¹. The light duration is usually set to a 12-16 hour light period and an 8-12 hour dark period to simulate the natural diurnal rhythm and ensure normal photomorphogenesis and physiological metabolism in the seedlings. Different spectral components also have different effects on seedling growth. Blue light promotes root development and leaf thickening, while red light is beneficial for stem elongation and chlorophyll synthesis.

[0027] Water is an indispensable factor for rice growth. From the moment the seed germinates, a sufficient supply of water is needed to initiate and maintain various physiological activities. During the seedling growth process, it is necessary to maintain appropriate soil or culture medium moisture to avoid excessive dryness, which can lead to seedling wilting due to water shortage, affecting growth or even death. Excessive moisture may cause problems such as root hypoxia and disease proliferation. The relative humidity of the air is generally best maintained at 60%-80%, which helps to reduce seedling water loss and maintain the water balance within the plant.

[0028] For soil cultivation, soil texture, fertility, and pH are crucial for seedling growth. Loose, fertile, and well-drained soil is conducive to root growth and respiration. The ideal soil pH is between 6.0 and 7.5, within which the availability of various mineral nutrients is higher and they can be better absorbed and utilized by the seedlings. If hydroponics is used, the nutrient solution formula needs to be precisely prepared, containing macroelements such as nitrogen, phosphorus, potassium, calcium, and magnesium, as well as microelements such as iron, manganese, zinc, and boron, to meet the nutritional needs of seedlings at different growth stages.

[0029] High-quality seeds are the foundation for cultivating robust seedlings. When selecting seeds, it is essential to ensure high purity and avoid mixing with other varieties or impurities. At the same time, the germination rate of the seeds should meet a certain standard, generally requiring more than 90%, to ensure a high emergence rate. In addition, seed vigor is also an important indicator. Seeds with high vigor exhibit stronger adaptability and growth potential during germination and seedling growth.

[0030] During seedling cultivation, close attention should be paid to the uniformity of seedling growth. By regularly measuring morphological indicators such as seedling height, leaf age, and number of leaves, and calculating their coefficient of variation, the uniformity of growth can be assessed. If significant differences in seedling growth are found, the reasons should be analyzed in a timely manner. These may involve issues such as seed quality, uneven environmental conditions, or differences in nutrient supply, and corresponding adjustment measures should be taken.

[0031] Pests and diseases can seriously affect the quality of rice seedlings and experimental results. Therefore, it is necessary to establish a sound pest and disease control system, install insect-proof nets in the cultivation facilities to prevent pests from entering, regularly disinfect facilities, equipment and seedling substrates to reduce the growth of pathogens, and strengthen daily observation of seedlings. Once signs of pests and diseases are found, appropriate control measures should be taken in a timely manner, such as biological control, physical control or rational use of chemical agents, but care should be taken to avoid pesticide residues interfering with experimental results.

[0032] Rice seedling cultivation is a comprehensive and systematic project involving the precise control of multiple links and factors. Starting from the cultivation principles, meeting the seedlings' environmental requirements, making reasonable use of various cultivation equipment and facilities, and strictly controlling key quality control points are essential to cultivate high-quality, uniformly growing rice seedlings. This provides a solid and reliable material foundation for subsequent rice experimental research and promotes the continuous deepening and development of rice scientific research.

The upper end of the support base 201 is equipped with a monitoring panel 202. The rear side wall of the cultivation pool 101 is equipped with a temperature probe 205 and a humidity probe 206 respectively. The temperature probe 205 and the humidity probe 206 are electrically connected to the monitoring panel 202. By combining the temperature probe 205 and the humidity probe 206, the temperature and humidity data of the rice seedling growth environment in the cultivation pool 101 are measured in real time and accurately, and the data is displayed intuitively on the monitoring panel 202.

[0036] A fixed support 203 is provided between the monitoring panel 202 and the cultivation pond 101. The lower end of the fixed support 203 extends to the surface of the cultivation platform 1, and a spherical monitoring probe 204 is provided at the upper end of the fixed support 203. The growth status of rice seedlings in the cultivation pond 101 is monitored in real time through the spherical monitoring probe 204, and the growth process of the seedlings can be clearly recorded, including the morphological changes of the seedlings and the occurrence of diseases and pests.

[0037] The bottom of the cultivation pond 101 is evenly provided with multiple sets of seepage holes 103, and the top of the rear side wall of the cultivation pond 101 is provided with multiple sets of fixing pipe clamps 7 in a linear manner. The fixing pipe clamps 7 are provided with elastic grooves 8 inside.

At the same time, the corresponding planting agents are added through the intermediate water reservoir 9.

[0039] The water supply distribution mechanism 4 includes a main water pipe 401, which is matched and engaged with the elastic groove 8 of the fixed pipe clamp 7. Multiple flow nozzles 402 are evenly arranged at the outer end of the main water pipe 401. One end of the main water pipe 401 extends through the sealing joint 10 into the interior of the intermediate water tank 9. A water pump 403 is provided at one end of the main water pipe 401. Through the multiple flow nozzles 402 evenly arranged at the outer end of the main water pipe 401, the water delivered from the main water pipe 401 can be evenly sprayed onto the rice seedlings in the cultivation pond 101. The water pump 403 provides power to efficiently transport the water in the intermediate water tank 9 to the cultivation pond 101.

[0040] A fixed base 15 is installed at the center of the upper end of the light distribution platform 5. An extension rod 16 is installed at the center of the surface of the base. A connecting block 17 is provided at the upper end of the extension rod 16. A rotating groove 18 is opened at the front end of the connecting block 17. Rotating holes 19 are opened on both sides of the rotating groove 18. A rotating shaft 601 is provided at the rear end of the sunlight simulation lamp 6. Both ends of the rotating shaft 601 extend into the interior of the rotating holes 19. Through the cooperation of the rotating groove 18 and rotating holes 19 on the connecting block 17 with the rotating shaft 601 at the rear end of the sunlight simulation lamp 6, the sunlight simulation lamp 6 can rotate within a certain angle range. This allows researchers to flexibly adjust the illumination angle of the sunlight simulation lamp 6 according to the growth needs of rice seedlings and experimental design, and simulate natural light conditions of different times and intensities.

[0041] The rear end of the light distribution platform 5 is provided with a battery compartment 501, and the battery compartment 501 contains a battery pack 13. The rear end of the battery compartment 501 is matched with a battery cover 14 that closes the battery compartment 501. The monitoring mechanism 2 and the sunlight simulation lamp 6 are electrically connected to the battery pack 13, and the battery pack 13 provides power support for the monitoring mechanism 2 and the sunlight simulation lamp 6.

[0042] During the operation, suitable cultivation soil is filled into the cultivation pool 101, and different varieties of rice seeds or seedlings are sown or transplanted at a specific planting density according to the experimental design. A suitable amount of clean irrigation water is injected into the transfer water tank 9 of the transfer water tank 3 through the water injection pipe 12. The tank cover 11 is closed, and the irradiation angle of the sunlight simulation lamp 6 is adjusted by using the cooperation of the rotating hole 19 and the rotating shaft 601 according to the light requirements of different growth stages of rice seedlings.

Researchers can understand the temperature and humidity of the cultivation environment by viewing the monitoring panel 202. Spherical monitoring probe 204 monitors the growth status of rice seedlings in the cultivation pond 101 in real time, and records information such as seedling morphological changes and the occurrence of diseases and pests. During irrigation, water pump 403 starts to work, and delivers water in transfer water tank 9 to the diversion nozzle 402 through main water pipe 401. The diversion nozzle 402 sprays water evenly onto the rice seedlings in the cultivation pond 101 to achieve precise irrigation.

[0044] Its working principle is as follows: temperature probe 205 and humidity probe 206 sense the temperature and humidity in the cultivation pool 101, respectively, convert the sensed physical signals into electrical signals, and transmit them to the monitoring panel 202. The spherical monitoring probe 204 takes pictures of the rice seedlings in the cultivation pool 101 from all angles through the optical imaging principle, and converts the captured video signals into electrical signals, which are then transmitted to the storage device connected to the monitoring panel 202 for storage. The transfer water tank 3's transfer water chamber 9 is used to store irrigation water. The water pump 403 serves as a power source. After being powered on, it generates a pressure difference, drawing water from the transfer water chamber 9 into the main water pipe 401. The water flows in the main water pipe 401 and is evenly dispersed into fine water streams when it reaches the evenly distributed diversion nozzles 402 at the outer end. These streams are then sprayed onto the rice seedlings in the cultivation pool 101 to achieve precise irrigation. The battery pack 13 in the battery compartment 501 stores electrical energy to provide power support for the monitoring mechanism 2 and the solar simulation lamp 6.

[0045] Its beneficial effects are significant. The cultivation platform 1 can be densely arranged in the laboratory or greenhouse to replace the traditional field experiment, reducing land occupation. The environment can be precisely controlled by the sunlight simulation lamp 6 and the water supply and distribution mechanism 4 to avoid interference from natural weather. The growth data can be automatically recorded by the spherical monitoring probe 204, temperature probe 205 and humidity probe 206, eliminating the error of manual measurement and supporting long-term dynamic analysis. Nutrient solution can be flexibly added by the transfer water tank 3 and the diversion nozzle 402 to ensure uniform irrigation. The seepage hole 103 prevents waterlogging.
