Description

TECHNICAL FIELD

[0001] The present application relates to the field of breeding technology, in particular to a rice salt-tolerant batch detection device for agricultural experiments. BACKGROUND

[0002] The total area of saline-alkali land in China exceeds 100 million hectares, of which about 35 million hectares has agricultural potential (data source: China saline-alkali land resources survey). Affected by salt-alkali stress, rice planting faces problems such as growth inhibition, yield reduction (reduction of 30%-50%) and quality deterioration. Cultivating salt-tolerant rice varieties has become an important strategic direction to ensure national food security, and efficient and accurate salt-tolerant identification technology is the key support for variety breeding.

[0003] Currently, rice salt-tolerance identification mainly relies on seedling stage water culture experiment, but the existing technology has the following limitations. For example, Chinese patent document CN213306614U discloses a rice seedling salt-tolerance identification device, which can simultaneously identify the salt-tolerance of multiple groups of rice seedlings with different salinity in the same device, the identification environment is more consistent, and the size of the holding area with the same salinity can be adjusted as needed, which is more flexible and can add salt-alkali liquid more uniformly. In addition, for example, Chinese patent document CN117356321B discloses a rice seedling salt-tolerance identification device, which can be seeded by setting a sowing device, without the need for manual seeding, achieving the effect of saving time. However, the above devices only improve the planting process, and still rely on manual operation for salt-alkali liquid preparation, environmental control, data recording and other core processes, which is prone to human error and difficult to meet the high-throughput screening demand.

[0004] Therefore, there is an urgent need for a new rice salt-tolerant batch detection device for agricultural experiments to provide an effective solution to the defects of the existing technology. SUMMARY

[0005] The present application aims to provide a rice salt-tolerant batch detection device for agricultural experiments to solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: An agricultural experimental rice salt-alkali tolerance batch testing device includes planting unit boxes and a main pipe: the main pipe connects to one or more planting unit boxes, each planting unit box has an open top with a horizontally extending baffle at the open end. A breeding frame is inserted into the inner side of the baffle, and planting grids are arranged in an array within the breeding frame. The bottom of each planting grid is connected to the planting unit box and is equipped with a fall-prevention net to prevent seeds from falling. The top edge of the breeding frame has a horizontally extending frame edge, which is stacked on top of the baffle and has a handle. The top of the front sidewall of each planting unit box has a high-concentration salt-alkali solution inlet, a pure water inlet, a nutrient solution inlet, and a drain outlet. The main pipe includes a drain pipe, a nutrient solution inlet pipe, a pure water inlet pipe, and a high-concentration salt-alkali solution inlet pipe arranged side by side. The nutrient solution addition pipe, pure water addition pipe, and high-concentration saline solution addition pipe correspond one-to-one with the drain outlet, nutrient solution addition outlet, pure water addition outlet, and high-concentration saline solution addition outlet and are detachably connected. Each of the high-concentration saline solution addition outlet, pure water addition outlet, and nutrient solution addition outlet is equipped with a solenoid valve and an electromagnetic flow meter. A circulation pump is installed on the right side wall of the planting unit box, and a horizontally arranged water drain pipe is provided at the bottom of the left side wall of the planting unit box. The water drain pipe is connected to the inlet end of the circulation pump through an inlet pipe, and the outlet end of the circulation pump is connected to the drain outlet through an outlet pipe. The planting unit box is equipped with a temperature sensor, a water level sensor, and a salinity sensor. The temperature sensor, water level sensor, salinity sensor, and circulation pump transmit signals to the control center through a wireless data transmission module.

[0007] Furthermore, the top right side wall of the planting unit box is provided with a horizontally arranged water supply pipe, the drain outlet is provided with a solenoid valve, the outlet pipe is connected to the water supply pipe, and the end of the water supply pipe away from the outlet pipe is connected to the water supply pipe.

[0008] Furthermore, the bottom of the inner cavity of the planting unit box is provided with an anti-clogging filter screen, which is parallel to the bottom of the inner cavity of the planting unit box.

[0009] Furthermore, a light intensity sensor is also provided above the planting unit box. The light intensity sensor also transmits signals to the control center through a wireless data transmission module. A rod sleeve is provided on the outer wall of the planting unit box. A vertical rod is inserted into the rod sleeve. A locking knob is threaded on the vertical rod. The light intensity sensor is installed on the top of the vertical rod.

[0010] Furthermore, the bottom of the planting unit box is equipped with rollers.

[0011] Furthermore, the planting unit box is made of an opaque material and has an insulation layer on its outer surface. The inner wall of the planting unit box is equipped with a semiconductor cooling chip and an electric heating plate. The semiconductor cooling chip also transmits signals to the control center through a wireless communication module.

[0012] Furthermore, each planting cell in the breeding frame is individually numbered, and different dense or sparse planting schemes can be selected during the testing process.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes automated, precise preparation of saline-alkali solutions, intelligent environmental control, and a wireless data transmission module to upload data such as temperature, salinity, and water level to a control center in real time. This automates the recording of the experimental process, reduces errors from manual recording, and facilitates subsequent data analysis. This invention solves the problems of traditional techniques, such as reliance on manual operation, uneven environmental control, and inefficient data recording, providing a precise, efficient, and scalable experimental platform for research on rice salt tolerance.

[0014] 2. In this invention, the circulating pump draws liquid from the tank through the inlet pipe, and delivers it to the water pipe on the right side wall through the upper water pipe. The liquid is then evenly sprayed onto the liquid surface in the tank through the horizontal branch pipe, avoiding local salt and alkali deposition. The liquid re-enters the circulating pump through the lower water pipe, forming a closed-loop flow of "bottom suction - top return", which effectively prevents salt and alkali crystallization.

[0015] 3. In this invention, the light intensity sensor sends data to the control center through a wireless data transmission module. The control center automatically adjusts the external light source or adjusts the shading measures according to the differences in light intensity data, thereby further improving the consistency of experimental conditions.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: As Figures 1-7As shown, an agricultural experimental rice salt-alkali tolerance batch testing device includes planting unit boxes 6 and a main pipe: the main pipe connects to one or more planting unit boxes 6. The top of the planting unit box 6 is open, and a horizontally extending baffle 15 is provided at the open. A breeding frame 12 is inserted and placed inside the baffle 15. Planting grids 14 are arranged in an array inside the breeding frame 12. The bottom of the planting grids 14 is connected to the planting unit box 6 and is provided with a seed-preventing net 25. The top edge of the breeding frame 12 is provided with a horizontally extending frame edge 23, which is stacked on the baffle 15. A handle 13 is provided on the frame edge 23. The top of the front wall of the planting unit box 6 is provided with a high-concentration salt-alkali solution inlet 10, a pure water inlet 9, a nutrient solution inlet 8, and a drain outlet 7. The main pipe includes a drain pipe 1, a nutrient solution inlet pipe 2, a pure water inlet pipe 3, and a high-concentration salt-alkali solution inlet pipe 4 arranged in parallel. The liquid addition pipe 2, pure water addition pipe 3, and high-concentration saline solution addition pipe 4 correspond one-to-one with the drain outlet 7, nutrient solution addition outlet 8, pure water addition outlet 9, and high-concentration saline solution addition outlet 10 and are detachably connected. Each of the high-concentration saline solution addition outlet 10, pure water addition outlet 9, and nutrient solution addition outlet 8 is equipped with a solenoid valve and an electromagnetic flow meter. A circulation pump 18 is installed on the right side wall of the planting unit box 6. A horizontally arranged water drain pipe 17 is provided at the bottom of the left side wall of the planting unit box 6. The water drain pipe 17 is connected to the inlet end of the circulation pump 18 through the inlet pipe 20. The outlet end of the circulation pump 18 is connected to the drain outlet 7 through the outlet pipe 22. The planting unit box 6 is equipped with a temperature sensor 28, a water level sensor 26, and a salinity sensor 27. The temperature sensor 28, water level sensor 26, salinity sensor 27, and circulation pump 18 transmit signals to the control center through a wireless data transmission module.

[0020] The bottom of the inner cavity of the planting unit box 6 is provided with an anti-clogging filter 24, which is parallel to the bottom of the inner cavity of the planting unit box 6.

[0021] The bottom of the planting unit box 6 is equipped with rollers 16.

[0022] The planting unit box 6 is made of opaque material and has an insulation layer on its outer surface. The inner wall of the planting unit box 6 is equipped with a semiconductor cooling chip and an electric heating plate. The semiconductor cooling chip also transmits signals to the control center through a wireless communication module.

[0023] Each planting cell 14 in the breeding frame 12 is individually numbered, and different dense or sparse planting schemes can be selected during the testing process.

[0024] Working principle of this embodiment: This implementation connects the high-concentration saline solution addition pipe 4, the pure water addition pipe 3, and the nutrient solution addition pipe 2 to the corresponding addition ports 10 / 9 / 8, respectively. Solenoid valves and electromagnetic flow meters precisely control the input ratio of each liquid, automatically preparing solutions with different saline-alkali gradients, such as 0.3%, 0.5%, and 0.8%. A salinity sensor 27 monitors the solution concentration in real time and feeds back to the control center to dynamically adjust the mixing ratio of saline-alkali solution and pure water, avoiding errors from manual preparation. A temperature sensor 28 monitors the temperature inside the chamber; if it exceeds the suitable range for rice, the control center activates the semiconductor cooling chip and electric heating plate to adjust, ensuring that the rice grows under constant temperature, water level, and salinity conditions, reducing external interference and improving experimental consistency. A water level sensor 26 monitors the liquid level and automatically maintains a constant water level through the drain port 7 or the replenishment port, ensuring uniform root contact with the solution. A circulation pump 18 draws liquid from the chamber through the drain pipe 17 and the inlet pipe 20. An anti-clogging filter 24 intercepts impurities, protecting the circulation pump 18 and extending the life of the device. The breeding frame 12 can be quickly inserted and removed via the frame edge 23 and the retaining edge 15. Each planting cell 14 is independently numbered, supporting different dense planting schemes, such as 10×10 or 15×15 arrangements. The casters 16 make the device easy to move and adapt to different experimental environments; the opaque material and heat insulation layer reduce external interference and prevent algae growth; the anti-fall net 25 prevents seeds or roots from falling and ensures the purity of experimental samples.

[0025] This embodiment utilizes automated, precise preparation of saline-alkali solutions, intelligent environmental control, and a wireless data transmission module to upload data such as temperature, salinity, and water level to the control center in real time. This automates the recording of the experimental process, reduces errors from manual recording, and facilitates subsequent data analysis. This embodiment solves the problems of traditional techniques, such as reliance on manual operation, uneven environmental control, and inefficient data recording, providing a precise, efficient, and scalable experimental platform for research on rice salt tolerance.

[0026] Example 2: Please refer to Figure 4 and 6 An agricultural experimental rice salt-alkali tolerance batch testing device, which differs from Example 1, is provided with a horizontally arranged water supply pipe 19 on the top of the right side wall of the planting unit box 6, a solenoid valve at the drain outlet 7, and a water supply pipe 21 connected to the water outlet pipe 22. The end of the water supply pipe 21 away from the water outlet pipe 22 is connected to the water supply pipe 19.

[0027] In this embodiment, the circulation pump 18 draws liquid from the tank through the inlet pipe 20, and delivers it to the upper water pipe 19 on the right side wall via the upper water pipe 21. The liquid is then evenly sprayed onto the liquid surface in the tank through horizontal branch pipes, preventing localized salt and alkali deposition. The liquid re-enters the circulation pump 18 through the lower water pipe 17, forming a closed-loop flow of "bottom suction - top return," effectively preventing salt and alkali crystallization. The drain outlet 7 remains closed during the circulation process.

[0028] Example 3: Please refer to Figure 8An agricultural experimental rice salt-alkali tolerance batch testing device, which differs from Example 1, is provided above the planting unit box 6 with a light intensity sensor 29. The light intensity sensor 29 also transmits signals to the control center through a wireless data transmission module. The outer wall of the planting unit box 6 is provided with a rod sleeve 31, and a vertical rod 30 is inserted into the rod sleeve 31. A locking knob is threaded on the vertical rod 30. The light intensity sensor 29 is installed on the top of the vertical rod 30.

[0029] In this embodiment, the light intensity sensor 29 is installed inside the insertion sleeve 31 via the upright 30. The height of the sensor can be adjusted up and down by loosening the locking knob. The sensor 29 monitors the light intensity inside the planting unit box 6 in real time and transmits the data to the control center via a wireless data transmission module. Although the planting experiments are located in the same space, there are still differences in light intensity. The control center automatically adjusts the external light source or adjusts the shading measures according to the differences in light data to ensure the consistency of experimental conditions.
