Description

Technical Field

[0001] This application relates to hydroponic plant devices, specifically to a large-scale hydroponic plant identification system. Background Technology

[0002] For the identification of salt and alkali tolerance in wheat, the main methods are to identify the bud stage, seedling stage, and the entire growth period. Among these, the bud and seedling stages are the main methods for identifying salt and alkali tolerance because they have a short growth period, are relatively easy to control under experimental conditions, and are relatively fast.

[0003] In germination period identification, methods such as petri dishes, germination paper, or germination bags are mainly used. These methods have mature experimental materials, standardized operating procedures, and good germination results, making them suitable for small to medium-scale experiments. However, in these experiments, each sample is treated as a separate unit. As the scale of the experiment increases, the total number of independent unit samples and the workload increase dramatically, leading to greater difficulty in controlling experimental conditions and making the investigation and comparison of independent units more challenging. To address the issues of scale, consistency, and efficiency in resource identification, a large-scale germination device with a uniform environment is needed.

[0004] Seedling identification often employs hydroponics and soil cultivation in pots. Hydroponics provides more uniform environmental stress, while soil cultivation more closely resembles field production. To facilitate large-scale identification and investigation of the underground parts of samples, hydroponics has become a more efficient identification method. However, it suffers from the same problems as the germination test mentioned above: independent hydroponic units are not conducive to uniformly controlling the growth environment, and the experimental management, data collection boxes, and sampling of independent units are not suitable for large-scale identification. Therefore, it is necessary to develop supporting devices and systems that address the issues of large-scale, consistent, and efficient identification.

[0005] Meanwhile, in the identification process, how to achieve continuous identification of the bud stage and the seedling stage, a longer growth stress period in the seedling stage, and a stress environment that is closer to salt stress in production are also key to carrying out large-scale accurate identification. Utility Model Content

[0006] The purpose of this application is to provide a large-scale hydroponic identification system for wheat with salt and alkali tolerance.

[0007] The plant large-scale hydroponic identification system according to this application includes a nutrient solution tank, a nutrient solution supply pipeline, a nutrient solution return pipeline, and a hydroponic tank, wherein,

[0008] The hydroponic tank is equipped with an overflow outlet and a drain outlet, both of which are connected to the return liquid pipeline.

[0009] The hydroponic tank is positioned above the liquid supply pipeline and the liquid return pipeline, and the hydroponic tank is connected to the liquid supply pipeline via the liquid inlet pipe.

[0010] According to the plant large-scale hydroponic identification system of this application, the inner bottom surface of the hydroponic tank is provided with a support.

[0011] According to the plant large-scale hydroponic identification system of this application, the nutrient solution tank is equipped with a submersible pump, and the submersible pump is connected to the nutrient solution supply pipeline.

[0012] According to the plant large-scale hydroponic identification system of this application, the liquid supply pipeline is connected to a mixing pipe, the end of the mixing pipe is sealed, and uniform small holes are punched on the pipe body.

[0013] The advantages of this utility model are:

[0014] The plant large-scale hydroponic identification system of this application can be used to conduct continuous identification of salt and alkali stress during the bud and seedling stages, which greatly improves the problem of heavy workload in stress environment control and large-scale identification in experiments.

[0015] For the large-scale hydroponic identification of wheat, this application adopts a large-scale hydroponic system that connects each hydroponic tank to circulate the nutrient solution or stress solution, so as to achieve consistency of the nutrient solution or stress solution in each hydroponic tank and ensure the uniformity of the stress environment.

[0016] This application addresses the large-scale hydroponic identification of wheat. From germination to seedling growth, the seedlings are grown in the same stress solution. By replacing the germination board and the floating board of the hydroponic seedbed, continuous identification of the two periods can be achieved, solving the problem that separating the two periods is not conducive to comprehensive evaluation.

[0017] The use of seed trays and floating boards in hydroponic troughs can prevent seed trays from becoming floating boards in hydroponic seedbeds, making it easy to remove them at any time for phenotypic surveys of roots and stems. After the survey, they can be put back to continue growing, enabling more efficient hydroponic culture of large samples and large-scale experiments, and providing better convenience for experimental surveys.

[0022] like Figure 1 and Figure 2As shown, the large-scale hydroponic identification system for plants according to this application includes: a nutrient solution tank 1, a nutrient solution supply pipeline 2, a nutrient solution return pipeline 3, and a hydroponic tank 4.

[0023] The hydroponic tank 4 is equipped with an overflow outlet 5 and a drain outlet 6, which are connected to the return liquid pipeline 3. The overflow outlet is directly connected to the return liquid pipeline without a valve, while the drain outlet is equipped with a valve. When the nutrient solution reaches the overflow outlet height, the excess nutrient solution flows through the overflow outlet and into the nutrient solution tank via the return liquid pipeline, thus achieving nutrient solution circulation.

[0024] The hydroponic tank is positioned above the liquid supply line 2 and the liquid return line 3, and the water inlet 9 of the hydroponic tank 4 is connected to the liquid supply line 2 through the liquid inlet pipe.

[0025] The inner bottom surface of the hydroponic trough 4 is provided with a cylindrical support 10, which helps to keep the germination trough board and seedling hydroponic board horizontal and stable in the hydroponic trough.

[0026] The nutrient solution tank 1 is equipped with a submersible pump 7, which provides power for the circulation of the nutrient solution in the entire system and is connected to the supply pipeline 2. The supply pipeline 2 is connected to a mixing pipe 8, which uses a pipe fitting smaller than the main pipeline, is sealed at the end, and has uniformly spaced small holes punched in the pipe body. Water at a higher pressure through the small holes remains in the nutrient solution tank to stir and mix the solution.

[0027] The plant-scale hydroponic identification system of this application was installed according to the actual site conditions. Each nutrient solution tank 1 contained a control nutrient solution and a stress nutrient solution, respectively. During the germination stage, trays were used. Wheat seeds were placed in the slots of the trays, and then the trays were placed in the hydroponic tanks 4. Nutrient solution was injected into the control hydroponic tanks, and stress nutrient solution was injected into the treatment hydroponic tanks, allowing the germination trays to float in the nutrient solution for seed germination. The top of the hydroponic tanks was covered with a cover plate or plastic sheet to reduce evaporation and ensure better germination conditions. Germination tests were conducted under natural light in a greenhouse at a temperature of 20°C. The germination rate was statistically analyzed on the 7th day. Salt tolerance during the germination stage was evaluated and identified by comparing the changes in the germination rate of different seed varieties under the control nutrient solution and stress nutrient solution conditions.

[0028] The elongated design of the germination trays ensures even seed distribution, facilitating rapid germination surveys and enabling large-scale trials. Furthermore, the roots of seedlings germinating on the trays grow vertically downwards, allowing for easy removal of each plant for individual variety assessments of seedling length, root length, and other parameters. Comparison of germination results from different trays also provides a direct and comparative evaluation. In addition to short-term seedling stress assessments, seedlings can continue growing in the germination plates for 10-15 days. For longer-term comparisons, seedlings can be transplanted to floating boards for hydroponic growth.

[0029] After 10 days of germination and when the seedlings have sprouted to over 5 cm in length, they can be transplanted from the germination plate to the floating plate for continued growth. Hydroponic sponge is used to transplant the seedlings into the holes of the floating plate, and the number of transplants can be controlled according to experimental requirements. The hydroponic tanks and nutrient solution are not changed, maintaining the same germination environment as before. During growth, the hydroponic circulation system runs continuously to ensure a consistent growth environment in all hydroponic tanks, with salinity and pH monitored every 5 days. After 30 days of growth, an investigation and evaluation are conducted. Sampling and measurements are taken of plant height, root length, biomass, chlorophyll content, enzyme activity, and ion content. Grading can also be performed based on phenotypes such as stem death and leaf withering after stress. A consistent aquatic growth environment facilitates sampling, investigation, and direct comparative evaluation.

However, the present invention is not limited to the specific embodiments described above, which are merely illustrative and not restrictive.
