Description

Technical Field

[0001] The present application relates to the technical field of rice cultivation, and in particular to a cultivation device for detecting the salt-alkali tolerance of rice seeds. Background Art

[0002] The salt-alkali tolerance of rice seeds refers to their ability to survive and germinate in a saline-alkali environment. This ability is essential for growing rice in saline-alkali land, especially in the context of global climate change and increasingly serious soil salinization. With the development and utilization of saline-alkali land, the research on salt-alkali tolerant rice has important practical significance. Through the detection and related research of salt-alkali tolerance, better variety selection and cultivation management programs can be provided for rice production, thereby increasing food production and ensuring food security. It has a far-reaching impact on agricultural production, ecological environment and food security.

[0003] For example, in the existing Chinese patent with publication number CN217011981U, a cultivation device for detecting the salt tolerance of rice is disclosed. Through the above-mentioned prior art, multiple cultivation boxes set in the device can adjust the internal salinity or replace different varieties of rice for cultivation without changing other conditions, so as to observe the growth of rice at the same time, facilitate recording and comparison, and improve work efficiency.

[0004] However, the above prior art has the following technical defects:

[0005] When the above-mentioned prior art is used, the control panel controls the cylinder to pull the support plate to move, and then the handle is used to open the rotating door, and the rice seedlings and cultivation materials are placed in each cultivation box respectively, and the salinity of the cultivation materials or the variety of the rice seedlings is adjusted as needed. First, when testing and cultivating the salt-alkali tolerance of rice, manual operation is required to control the salinity in the cultivation materials and the amount of rice put in. Due to manual control, the salinity and the amount of rice put in cannot be accurately controlled, so that the data obtained from subsequent tests will be biased.

[0006] Secondly, when the above device is used to detect cultivated rice, since the cultivation box is fixed to the bottom surface of the placement box, the rice plants can only be taken out directly from the cultivation box, which may easily cause damage to the cultivated rice plants during the process.

When the rice seeds are cultured for the salt-alkali tolerance detection, the amount of saline-alkali solution and rice seeds required for the culture can be controlled. At the same time, multiple different varieties of rice can be cultivated, and the cultured rice plants can be easily taken out for observation and detection.

[0042] Embodiment 1:

[0043] Reference Figures 1 to 3 As shown, the present application provides a culture device for testing the salt-alkali tolerance of rice seeds, comprising a culture platform 1 and an upper platform 11 installed on the culture platform 1, a supporting seat 12 is arranged on one side of the culture platform 1, and a culture mechanism 2 is arranged on the culture platform 1 and the upper platform 11; it is used for cultivating the salt-alkali tolerance of rice, and can accurately place rice seeds and raw materials required for cultivation, and when testing is required, it is convenient to take out the rice plants to prevent damage to the rice plants.

[0044] In this embodiment, the culture mechanism 2 preferably includes three supporting horizontal plates 21 equidistantly slidably arranged on the culture platform 1, rectangular slide grooves 101 for slidingly installing the supporting horizontal plates 21 are equidistantly provided on the culture platform 1, three metal round seats 22 are equidistantly embedded on the supporting horizontal plates 21, and circular grooves 211 for installing the metal round seats 22 are equidistantly provided on the supporting horizontal plates 21. Three culture round boxes 23 are placed on the supporting horizontal plates 21 in sequence, and circular magnets 24 adapted to the metal round seats 22 are installed at the bottom of the culture round boxes 23; through the adsorption and cooperation between the circular magnets 24 and the metal round seats 22, the culture round boxes 23 can be stably placed on the supporting horizontal plates 21.

[0045] A transparent protective cover 14 is installed on the culture platform 1 through two limiting side plates 13 to slide up and down, and a plurality of ventilation holes 141 are provided on both sides of the transparent protective cover 14. Limiting slide grooves 102 are provided on both sides of the culture platform 1 for sliding installation of the limiting side plates 13. The culture platform 1 and the supporting horizontal plate 21 are provided with bottom entry grooves 103 adapted to the bottom of the transparent protective cover 14. When in use, the transparent protective cover 14 is first pushed upward, the three supporting horizontal plates 21 are pulled out in sequence, and the soil required for cultivation is added to the culture round box 23. After the addition is completed, the transparent protective cover 14 is pushed back to snap into the bottom entry groove 103.

[0046] The upper platen 11 is provided with a feeding unit 3 for quantitatively feeding raw materials, which is used to feed saline-alkali solution and rice seeds of different varieties into the culture round box 23. The addition of saline-alkali solution makes the soil in the culture round box 23 form saline-alkali soil, providing a saline-alkali environment for seed cultivation. The support seat 12 and the culture table 1 are provided with a liquid supply component 4, which is used to transport growth water into the culture round box 23 during cultivation.

[0047] Reference Figure 4 As shown, in order to accurately place the rice seeds and the saline-alkali solution of the culture, the placing unit 3 includes a side plate 31 arranged at the upper end of the culture platform 1. In this embodiment, three upper seed boxes 32 are equidistantly installed on one side of the side plate 31 located above the upper platform 11, and three lower seed tubes 33 penetrating the upper platform 11 are equidistantly arranged on the lower side of the upper seed box 32. The three lower seed tubes 33 on the lower side of each upper seed box 32 are respectively located directly above the three culture round boxes 23 on the three supporting horizontal plates 21. Nine round through holes 111 are opened on the upper platform 11 for installing the lower seed tubes 33. The upper seed box 32 is provided with a main regulator 5 for controlling the amount of rice seeds placed. A solution injection piece 6 is provided on one side of the upper seed box 32, which can add different amounts of saline-alkali solution to the culture round boxes 23 on the three supporting horizontal plates 21, respectively, to achieve different saline-alkali cultivation environments.

[0048] When in use, different varieties of rice seeds can be added to the three upper seed boxes 32 respectively, so that when the seeds are put in through the main regulator 5, different varieties of rice seeds can be cultivated in the cultivation round boxes 23 on the three supporting horizontal plates 21. Three cultivation round boxes 23 are placed on each supporting horizontal plate 21, and the seed varieties and soil salinity and alkali conditions in the cultivation round boxes 23 on the same supporting horizontal plate 21 are the same, so as to ensure the accuracy of the data when the rice plants are tested after cultivation.

[0049] Reference Figure 5 and Figure 6 As shown, since it is necessary to control the different seed amounts to be put into the culture round boxes 23 on different supporting horizontal plates 21, the main regulator 5 includes an inner bottom plate 51 arranged in the upper seed box 32, and the inner bottom plate 51 has a delivery hole 511 connected to the lower seed tube 33, and the delivery hole 511 is set through the inner bottom plate 51; the upper seed box 32 is provided with a bottom plate socket 321 for the inner bottom plate 51 to be installed, and a regulating plug 52 is slidably inserted in the inner bottom plate 51, and three regulating holes 521 adapted to the delivery hole 511 are penetrated and opened on the regulating plug 52, and a plate slot 512 connected to the delivery hole 511 and for the regulation plug 52 to be inserted and installed is opened in the inner bottom plate 51. A limiting rod 53 for limiting the regulating plug 52 is installed on the outer side of the upper seed box 32.

[0050] When it is necessary to put rice seeds into the cultivation round box 23, the regulating plug 52 is pulled outward until one end of the regulating plug 52 contacts the limiting rod 53. At this time, the regulating hole 521 on the regulating plug 52 will coincide with the placing hole 511, and the seeds in the upper seed box 32 can fall into the cultivation round box 23 through the lower seed tube 33. Then, the regulating plug 52 is pushed to insert and reset to stop the seeds from falling. It is possible to control the falling amount of rice seeds in different upper seed boxes 32 by controlling the time of driving the regulating plug 52.

[0051] It is possible to cultivate three different varieties of rice in the culture round boxes 23 placed on the three supporting horizontal plates 21, and three culture round boxes 23 are placed on each supporting horizontal plate 21, so that the grown rice plants can occupy a culture round box 23 separately, and it is convenient to take out a single culture round box 23 to test the rice plants.

[0052] Reference Figure 7As shown, considering the need to form a saline-alkali environment in the culture round box 23 to provide conditions for the cultivation of rice seeds for salt-alkali tolerance testing, the solution injection member 6 includes a solution box 61 installed on one side of the upper seed box 32, and the solution box 61 is used to store saline-alkali solution. In this embodiment, three solution tubes 62 are preferably connected to the bottom of the solution box 61, and one end of the solution tube 62 penetrates and extends into the lower seed tube 33, and one end of the solution tube 62 penetrates and extends into the corresponding lower seed tube 33. The lower seed tube 33 is provided with a tube jack 331 for the solution tube 62 to penetrate and extend, and a sub-regulator 7 is provided in the solution box 61 to control the input amount of saline-alkali solution in the solution box 61. Before seed cultivation, appropriate amounts of saline-alkali solution are added to the three solution boxes 61 respectively, and then the sub-regulator 7 is used to control the metering of each solution box 61 into the culture round box 23 placed on the corresponding lower supporting horizontal plate 21. To achieve the purpose of providing different saline-alkali environments.

[0053] Reference Figure 8 and Fig. 9 As shown, in order to be able to control the different salinity levels in the culture round boxes 23 on different supporting horizontal plates 21, the auxiliary regulator 7 includes an inner bottom rod 71 installed in the solution box 61, and the inner bottom rod 71 has a liquid delivery hole 711 connected to the solution tube 62, and the liquid delivery hole 711 is set through the inner bottom rod 71; the solution box 61 is provided with a bottom rod socket 611 for the inner bottom rod 71 to be installed, and the inner bottom rod 71 is slidably inserted with a regulating plug rod 72, and the regulating plug rod 72 is penetrated with three liquid control holes 721 adapted to the liquid delivery hole 711, and the inner bottom rod 71 is provided with a rod slot 712 connected to the liquid delivery hole 711 and for the regulating plug rod 72 to be inserted and installed. A limiting outer rod 73 is installed on the outside of the solution box 61 to limit the regulating plug rod 72.

[0054] Pull the regulating rod 72 outward to make it collide with the limiting outer rod 73, and the liquid control hole 721 on the regulating rod 72 will overlap with the liquid delivery hole 711, and the saline-alkali solution in the solution box 61 will fall into the corresponding culture round box 23 through the solution tube 62, so that the soil previously added to the culture round box 23 forms saline-alkali soil. Control the time of pushing the regulating rod 72 to reset to achieve the metering control of the saline-alkali solution. By driving the regulating rods 72 in the three solution boxes 61, different saline-alkali soils can be achieved in the three culture round boxes 23 on the supporting horizontal plate 21. Provide different saline-alkali growth environments for rice seed cultivation.

[0055] Reference Fig.10 and Fig.11As shown, since it is necessary to regularly replenish the growing water required for rice in the culture box 23 during the rice seed cultivation process, the liquid supply component 4 includes a water tank 41 arranged on the supporting seat 12. In this embodiment, it is preferred that the water tank 41 is connected with three water supply pipes 42 that penetrate the culture platform 1 and extend to the top of the culture box 23, and the three water supply pipes 42 are respectively located above the three supporting horizontal plates 21. The culture platform 1 has an extended through hole 104 for the water supply pipe 42 to penetrate and install, and a water supply pump 43 is arranged on the water supply pipe 42 located on one side of the water tank 41. The water supply pipe 42 located above the culture box 23 has three annular parts 44, and a plurality of spray heads 45 are arranged on the lower side of the annular part 44. It should be noted that each water supply pipe 42 has three annular parts 44 of the same size, and a plurality of seed lowering pipes 33 are respectively located in the annular parts 44 at corresponding positions.

[0056] When the water supply pump 43 is started, the water in the water tank 41 can be transported to the water supply pipe 42, and then enter the annular portion 44 on the water supply pipe 42, and finally sprayed into the corresponding culture round box 23 through the spray head 45 on the lower side of the annular portion 44. Thus, the required growth water can be provided for the rice seeds. The purpose of planting the rice seeds in the saline-alkali environment can be achieved. After the seeds grow into rice plants, the supporting horizontal plate 21 at the corresponding position can be pulled out and the culture round box 23 can be taken out to observe and test the rice plants.

[0057] Embodiment 2:

[0058] Reference Fig.12 and Fig.13 As shown, on the basis of Example 1, considering that when there is no need to sow seeds and put saline-alkali solution, in order to be able to lock the positions of the regulating plug plate 52 and the regulating plug rod 72, to avoid the adjustment hole 521 on the regulating plug plate 52 and the putting hole 511 overlapping, and the liquid control hole 721 on the regulating plug rod 72 and the liquid delivery hole 711 overlapping, resulting in the automatic falling of seeds and saline-alkali solution, a locking member 8 is further provided in the inner bottom plate 51 and the inner bottom rod 71, and the locking member 8 includes a bar magnet 81 embedded in the inner end of the regulating plug plate 52, one end of the regulating plug plate 52 has a plug plate groove 522 for installing the bar magnet 81, and the inner bottom plate 51 is located in the plate slot 512 and is fixed with an inner iron block 82 that attracts the bar magnet 81. When the regulating plug 52 is fully inserted into the plate slot 512 of the inner bottom plate 51, the inner iron block 82 will enter the plug groove 522 and attract the bar magnet 81, thereby locking the position of the regulating plug 52 through the suction force, thereby preventing the regulating plug 52 from sliding by itself and causing the seeds in the upper seed box 32 to fall automatically.

[0059] The inner end of the regulating plug rod 72 is embedded with a bar magnet 83, and one end of the regulating plug rod 72 has a plug rod groove 722 for installing the bar magnet 83. The inner bottom rod 71 is located in the rod slot 712 and fixed with an inner iron sheet 84 that attracts the bar magnet 83. When not in use, when the regulating plug rod 72 is fully inserted into the rod slot 712 of the inner bottom rod 71, the inner iron sheet 84 will enter the plug rod groove 722 and attract the bar magnet 83. This achieves the purpose of locking the position of the regulating plug rod 72. It prevents the regulating plug rod 72 from automatically sliding, so that the saline-alkali solution in the solution box 61 automatically flows out.

[0060] The implementation principle of this embodiment is:

[0061] (1) Placement by suction: When in use, push up the transparent protective cover 14, then pull out the three supporting horizontal plates 21 in sequence, and through the adsorption and cooperation between the round magnet 24 and the metal round seat 22, place multiple round culture boxes 23 stably on the three supporting horizontal plates 21 in sequence. Then add the soil required for cultivation into the round culture boxes 23.

[0062] (2) Adding salt and alkali: Pull out the regulating rod 72 to make it contact with the limiting outer rod 73, and the salt and alkali solution in the solution box 61 falls into the corresponding culture round box 23 through the solution tube 62, so that the three regulating rods 72 can be driven and controlled separately, so that different salt and alkali culture environments are provided on the three supporting horizontal plates 21.

[0063] (3) Seed placement: Then pull the regulating plug plate 52 outward until one end of the regulating plug plate 52 contacts the limiting rod 53. The seeds in the upper seed box 32 fall into the corresponding round culture box 23 through the lower seed tube 33. By controlling the three regulating plug plates 52 differently, the falling amount of the rice seeds in the three upper seed boxes 32 can be controlled respectively.

[0064] Different varieties of rice can be cultivated in the culture round boxes 23 on the three supporting horizontal plates 21, and the grown rice plants can occupy a single culture round box 23, so that a single culture round box 23 can be taken out to detect the rice plants.

[0065] (4) Spraying water supply: When the water supply pump 43 is started, the water in the water storage tank 41 is first pumped into the water supply pipe 42, and then enters the annular portion 44, and is sprayed into the corresponding culture round box 23 through the spray head 45 on the lower side of the annular portion 44. Thus, the seeds can be supplied with the required growth water.

[0066] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
