Description

Technical Field

[0001] The invention belongs to the technical field of rice planting, and in particular relates to a small test field for growing rice with hydrogen water and a test method thereof. Background Art

[0002] Rice, a cereal crop of the genus Oryza in the Poaceae family, is the staple food of more than half of the world's population. In many rice-growing countries and regions, rice cultivation occupies an important position in agriculture and is one of the main sources of income for farmers. The rice industry covers multiple links such as planting, processing, and sales, which has effectively driven the employment of a large number of rural laborers and greatly promoted the development of the rural economy. With the continuous growth of the global population, the demand for food continues to rise. In order to better meet the growing population's demand for food, it is imperative to optimize rice planting methods and improve rice yield and quality. Among them, hydrogen water rice, as an emerging planting technology, has unique advantages. Hydrogen has antioxidant and plant hormone regulating effects. During the growth of rice, an appropriate amount of hydrogen supply can promote the development of the rice root system, making it more developed, thereby enhancing the ability to absorb water and nutrients, and ultimately increasing rice yield.

[0003] At present, in the experimental process of growing rice with hydrogen water, the commonly used method is to first use professional hydrogen water preparation equipment to successively produce hydrogen water of different concentrations, and then irrigate the hydrogen water of each concentration to different experimental areas where rice is planted. In this way, the effects of hydrogen water of different concentrations on rice growth can be compared. However, hydrogen water production equipment that can prepare a variety of different concentrations of hydrogen water with high precision is usually expensive. In addition, since the solubility of hydrogen in water is relatively low and it is easy to escape, the concentration of the hydrogen water prepared first will be reduced due to the escape of hydrogen, which will affect the test results. Summary of the invention

[0010] Furthermore, a first adjusting wheel is rotatably engaged with the upper surface of the first mounting plate, and a second adjusting wheel is rotatably engaged with the upper surface of the second mounting plate. A plurality of first arc grooves are penetrated through the upper surface of the first adjusting wheel, and a plurality of second arc grooves are penetrated through the upper surface of the second adjusting wheel. A connecting rod is fixedly connected to the other end of the connecting plate, and a plurality of the connecting rods are respectively slidably engaged with a plurality of the first arc grooves and the second arc grooves. When the first adjusting wheel or the second adjusting wheel rotates a certain angle, the first arc groove or the second adjusting wheel will drive the plurality of connecting rods to move different distances respectively.

[0011] Furthermore, the first adjusting wheel and the second adjusting wheel are both rotatably matched with driving wheels on their circumferential sides, one end of the driving wheel is fixedly connected to a rotating shaft, the two rotating shafts respectively penetrate the first mounting plate and the second mounting plate for rotational cooperation, and one end of the rotating shaft is fixedly connected to a servo motor.

[0012] Furthermore, the rice experimental field includes a plurality of experimental areas, and drip irrigation pipes are arranged in the experimental areas. One of the drip irrigation pipes is connected to one of the water outlet pipes close to the second installation frame.

[0020] Step 6: directly discharge the irrigation water in the sleeve into the drip irrigation pipe through the outlet pipe close to the second installation frame, and then irrigate the irrigation water into the test area in the rice test field through the drip irrigation pipe to set up a blank control group;

[0021] Step 7: During the growth of rice, regularly measure the growth and physiological indicators of rice to analyze the differences between different control groups, and after the rice matures, analyze the rice yield and quality of each experimental area.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention arranges a plurality of metering pieces to absorb high-concentration hydrogen water prepared by a hydrogen water preparation device or irrigation water in a water tank, and adjusts the absorbed capacity, and then discharges the high-concentration hydrogen water or irrigation water in the metering pieces into a mixing tank for mixing, thereby obtaining hydrogen water of different concentrations. Thus, only one single-concentration hydrogen water preparation device is needed to meet the test requirements, thereby reducing the test cost.

[0024] 2.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] The mixing component includes a first mounting frame 7 and a second mounting frame 8. A plurality of metering members 9 are fixedly installed in a circumferential array in the first mounting frame 7 and the second mounting frame 8. The metering member 9 includes a sleeve 10. A piston rod 11 is slidably fitted in the sleeve 10. One end of the sleeve 10 is fixedly connected with two one-way valves 12. One end of one of the one-way valves 12 is fixedly connected with a water inlet pipe 13. One end of the other one-way valve 12 is fixedly connected with a water outlet pipe 14. A plurality of water inlet pipes 13 near the first mounting frame 7 are fixedly connected with the first multi-way pipe joint 4. A plurality of water inlet pipes 13 near the second mounting frame 8 are fixedly connected with the second multi-way pipe joint 5. One end of a water outlet pipe 14 near the first mounting frame 7 and one end of a water outlet pipe 14 near the second mounting frame 8 are fixedly connected with a mixing tank 15.

[0037] By pulling each piston rod 11 to utilize air pressure, the several water inlet pipes 13 close to the first installation frame 7 absorb the prepared high-concentration hydrogen water into the sleeve 10 connected thereto, and the several water inlet pipes 13 close to the second installation frame 8 absorb the irrigation water in the water tank 3 into the sleeve 10 connected thereto, and then push each piston rod 11 in the reverse direction to make the water outlet pipe 14 discharge the high-concentration hydrogen water and irrigation water in the sleeve 10 into the several mixing tanks 15 in turn for mixing, so that different concentrations of hydrogen water are stored in each mixing tank 15.

[0038] A first mounting plate 16 is fixedly mounted in the first mounting frame 7, and a second mounting plate 17 is fixedly mounted in the second mounting frame 8.

A connecting plate 19 is slidably fitted in the slide groove 30. A plug rod 20 is fixedly connected to the upper surface of the connecting plate 19. A connecting block 21 is fixedly connected to one end of the piston rod 11. The plug rod 20 is plugged into and fitted with the connecting block 21.

[0039] The first mounting plate 16 and the second mounting plate 17 are rotatably matched with the first adjusting wheel 18 and the second adjusting wheel 31 at one end, respectively. The first adjusting wheel 18 is penetrated with a plurality of first arc grooves 22 at one end, and the second adjusting wheel 31 is penetrated with a plurality of second arc grooves 6 at one end. The other end of the connecting plate 19 is fixedly connected with a connecting rod 23, and the plurality of connecting rods 23 are respectively slidably matched with the plurality of first arc grooves 22 and the second arc grooves 6. The starting end points of the plurality of first arc grooves 22 or the second arc grooves 6 are arranged in a circular array, and the starting end points of two adjacent first arc grooves 22 or the second arc grooves 6 are aligned with each other. The angle between the line connecting the center points of the first adjusting wheel 18 or the second adjusting wheel 31 and the radius where the end points are located increases linearly. Therefore, when the first adjusting wheel 18 or the second adjusting wheel 31 rotates a certain angle, the first arc grooves 22 or the second arc grooves 6 will respectively drive the connecting rods 23 to move different distances, so that the connecting plates 19 in the first mounting plate 16 or the second mounting plate 17 move different distances, so that the piston rods 11 move different distances, so as to extract different capacities of hydrogen water or irrigation water, and just make the capacity of the mixed hydrogen water in the mixing tank 15 the same;

[0040] The first adjusting wheel 18 and the second adjusting wheel 31 are both rotatably matched with the driving wheel 24 on their circumferential sides, and one end of the driving wheel 24 is fixedly connected with a rotating shaft 25, and the two rotating shafts 25 are respectively penetrated and rotatably matched with the first mounting plate 16 and the second mounting plate 17, and one end of the rotating shaft 25 is fixedly connected with a servo motor 26;

[0041] By analyzing the hydrogen water concentration required by the control group, the two servo motors 26 are controlled to rotate at set angles respectively, thereby driving the two driving wheels 24 to rotate. The two driving wheels 24 respectively drive the first adjusting wheel 18 and the second adjusting wheel 31 meshed with their gears to rotate, so that the connecting rod 23 slides in the first arc groove 22 or the second arc groove 6, thereby pushing the connecting plate 19 to slide in the slide groove 30, so that the connecting plate 19 pushes the piston rod 11 to move through the insertion rod 20, so as to prepare high-concentration hydrogen water and irrigation water for mixing.

[0042] The rice experimental field 1 includes several experimental areas. Rice varieties with relatively consistent characteristics are planted in each experimental area, and hydrogen water with different concentrations is irrigated into each experimental area. At the same time, one experimental area is only irrigated with irrigation water, which serves as a blank control group.

[0043] A drip irrigation pipe 29 is provided in the test area, and the drip irrigation pipe 29 is connected to a water outlet pipe 14 near the second installation frame 8, and a storage tank should be provided between the drip irrigation pipe 29 and the water outlet pipe 14. An agitator 27 is fixedly installed in the mixing tank 15, and the agitator 27 is used to assist the high-concentration hydrogen water and irrigation water in the mixing tank 15 to be fully mixed. A connecting pipe 28 is fixedly connected to one end of the mixing tank 15, and the connecting pipe 28 is fixedly connected to the drip irrigation pipe 29.

[0044] When the high-concentration hydrogen water and irrigation water in the mixing tank 15 are mixed, the valves at the front ends of the drip irrigation pipes 29 are opened to allow the hydrogen water of different concentrations in the mixing tanks 15 and the irrigation water in the storage tanks to flow into the drip irrigation pipes 29 respectively, and then irrigate into the test areas through the drip irrigation pipes 29, thereby forming multiple control groups and reducing the storage time of the hydrogen water to avoid the reduction of the hydrogen water concentration due to the escape of hydrogen, which affects the accuracy of the test structure.

[0048] Step 3: Prepare high-concentration hydrogen water through the hydrogen water preparation device 2, start the two servo motors 26 to drive the first adjustment wheel 18 and the second adjustment wheel 31 to rotate the set angles respectively, so that the connecting plate 19 moves along the slide groove 30, and drives the piston rod 11 to move synchronously. Under the action of air pressure, the several water inlet pipes 13 close to the first installation frame 7 absorb the prepared high-concentration hydrogen water into the sleeve 10 connected thereto, and the several water inlet pipes 13 close to the second installation frame 8 absorb the irrigation water in the water tank 3 into the sleeve 10 connected thereto;

[0049] Step 4: Start the two servo motors 26 to drive the first adjusting wheel 18 and the second adjusting wheel 31 to rotate in opposite directions at set angles, so that the water outlet pipe 14 discharges the high-concentration hydrogen water and irrigation water in the sleeve 10 into the plurality of mixing tanks 15 in sequence for mixing, and then the hydrogen water and irrigation water are fully mixed by the agitator 27, so that the plurality of mixing tanks 15 store hydrogen water of different concentrations respectively;
