Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural breeding technology, and in particular relates to a salt-tolerant germination device for corn seeds. Background Technology
[0002] In agriculture, maize, as an important food and cash crop, has its planting area and yield constrained by various environmental factors, among which soil salinization is one of the key factors seriously affecting maize growth and yield. With the impact of global climate change and human activities, soil salinization has become increasingly serious, leading to the degradation of large amounts of arable land and posing a significant challenge to agricultural production. Therefore, improving the salt and alkali tolerance of crops such as maize has become one of the important directions of current agricultural research.
[0003] In studies of maize's salt and alkali tolerance, the salt and alkali tolerance during seed germination is a crucial indicator for assessing its overall salt and alkali tolerance. However, traditional methods for testing seed salt and alkali tolerance germination often require the precise pre-preparation of multiple salt and alkali solutions of varying concentrations to meet different testing needs. This process is not only cumbersome and time-consuming, but also prone to affecting the reliability and repeatability of test results due to inaccurate control of solution concentration. Furthermore, the frequent replacement and preparation of salt and alkali solutions of different concentrations during testing increases experimental costs and the risk of contamination.
[0004] To address the aforementioned issues and improve the efficiency and accuracy of salt-alkali tolerance germination tests for maize seeds, researchers and engineers are continuously exploring new testing methods and technologies. Among these, designing a salt-alkali tolerance germination device based on the principle of gradient concentration variation has emerged as an innovative and practical solution. By designing a rational device structure, a gradient concentration distribution naturally forms within the device when using salt-alkali solutions of the same initial concentration. This eliminates the need for pre-mixing multiple solutions of different concentrations, enabling seed germination tests at varying salt-alkali concentrations.
[0005] However, there is currently a lack of a device on the market that is simple in structure, easy to operate, and capable of efficiently testing the salt and alkali tolerance of maize seeds. Therefore, developing a novel salt and alkali tolerance germination device for maize seeds is of great significance for promoting research on the salt and alkali tolerance of maize and improving agricultural production efficiency.
[0006] Based on the above background and technical requirements, this utility model designs a salt-alkali tolerant germination device for corn seeds.
[0007] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation
[0034] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1:
[0036] Please see Figure 1-8 As shown, this utility model is a salt-alkali tolerant germination device for corn seeds, including a salt-alkali solution gradient mixing tray 1, a salt-alkali solution cultivation tray 2, a seed cultivation tray 3, a stopper 4, and cotton thread 5. The salt-alkali solution gradient mixing tray 1 is provided with four rows of salt-alkali solution dispensing tanks 11 with successively decreasing heights.
[0037] The gradient mixing tray 1 for saline-alkali solutions has four rows of successively decreasing height dispensing tanks 11 for holding saline-alkali solutions of the same initial concentration. Through the design of decreasing height, combined with subsequent solution outflow and dilution steps, different gradient saline-alkali solution environments can be achieved without the need for pre-precise preparation of multiple saline-alkali solutions of different concentrations. A first circular through-hole 12 is provided at the bottom of the gradient mixing tray 1 for controlling the outflow of saline-alkali solutions. A stopper 4 is installed on the first circular through-hole 12 to close or open it. The gradient mixing tray 1 also includes a first rectangular tank 13, with the four rows of successively decreasing height dispensing tanks 11 fixed to the inner bottom of the first rectangular tank 13. The first circular through-hole 12 penetrates the bottom of the first rectangular tank 13, and a first drain pipe 14 is fixed through and fixed to one end of the bottom of the first rectangular tank 13 for draining excess saline-alkali solution. A pair of hand-held support plates 15 are symmetrically fixed at both ends of the first rectangular tank 13 for easy operation and movement.
[0038] The saline-alkali solution cultivation tray 2 is equipped with four rows of breeding saline-alkali solution storage tanks 21 of equal height, used to receive the saline-alkali solution flowing down from the saline-alkali solution gradient mixing tray 1 and further dilute it. A coaxially arranged pointed needle 22 is fixed at the bottom of the breeding saline-alkali solution storage tank 21, with the upper end of the needle 22 extending beyond the storage tank 21 to open the stopper 4. The saline-alkali solution cultivation tray 2 also includes a second rectangular tank 23, within which the four rows of breeding saline-alkali solution storage tanks 21 of equal height are fixed. A second drain pipe 24 is fixed through the bottom of one end of the second rectangular tank 23 for draining excess liquid or replacing the solution.
[0039] The seed cultivation tray 3 has four rows of breeding troughs 31 of equal height for placing corn seeds for germination testing. A third through-hole 33 is provided at the bottom of each breeding trough 31. One end of a cotton thread 5 passes through the third through-hole 33, and the other end of the cotton thread 5 is coiled inside the breeding trough 31 to draw saline solution from the saline solution storage tank below to the seeds. A second through-hole 32 is also provided at the bottom of the breeding trough 31, which cooperates with a needle 22 to fix the position of the seed cultivation tray 3 on the saline solution cultivation tray 2. The seed cultivation tray 3 includes a rectangular plate 34, with the breeding trough 31 fixedly mounted on the upper surface of the rectangular plate 34. Both the second through-hole 32 and the third through-hole 33 penetrate the breeding trough 31 and the rectangular plate 34.
[0040] The salt and alkali tolerance test procedure for the corn seed salt and alkali tolerance germination device is as follows:
[0041] The first step involves taking high-concentration saline solution in a gradient volume manner. The saline solution gradient mixing tray 1 and the stopper 4 are then used to seal four rows of saline solution dispensing tanks 11 with progressively decreasing heights. A suitable high-concentration saline solution is prepared and poured into the four rows of dispensing tanks 11 with progressively decreasing heights, filling each tank completely. Excess solution is discharged from the first drain pipe 14.
[0042] The second step involves gradient preparation of the saline-alkali hydroponic environment. The gradient preparation tray 1 from step one is placed on the saline-alkali culture tray 2. The stopper 4 is pushed out by the needle 22, allowing the high-concentration saline-alkali solution in the dispensing tank 11 to flow down the needle 22 into the breeding saline-alkali storage tank 21 below. Because the height of the dispensing tank 11 decreases progressively, the flow rate and volume of the solution will vary. Combined with the subsequent injection of clean water, different gradient saline-alkali hydroponic environments can be achieved. Subsequently, clean water is injected into the breeding saline-alkali storage tank 21, stopping the injection when the water level is 2mm from the port, thus achieving a gradient saline-alkali hydroponic environment with decreasing concentration.
[0043] The third step is to cultivate corn seeds by threading cotton thread 5 through the third through hole 33 in each breeding trough 31, and then coiling half of the cotton thread 5 inside the breeding trough 31. Then, place the seed cultivation tray 3 on the saline-alkali solution cultivation tray 2 from step two. The cotton thread 5 is drawn upward from the prepared gradient saline-alkali solution. Place the corn seeds on the cotton thread 5 in the breeding trough 31, and then cover with culture soil and wait for the corn seeds to germinate.
[0044] The fourth step is observation and recording. The germination status of maize seeds in each breeding tank 31 is observed and recorded regularly. For the experimental group where germination occurs between germinating and non-germinating maize seeds, the concentration of the corresponding saline-alkali solution in the breeding saline-alkali storage tank 21 is measured and recorded. This step reduces the workload of precisely adjusting the saline-alkali solution concentration during salt-alkali tolerant germination of maize seeds and improves testing efficiency.
[0045] This embodiment achieves the goal of rapidly testing the salt and alkali tolerance of maize seeds by adjusting the concentration of the salt and alkali solution without prior precision through the above steps, providing an effective experimental method for studying the salt and alkali tolerance of maize seeds.
