One end of the two water outlet pipes 307 is fixedly connected with the irrigation mechanism 4 and the drip irrigation mechanism 5 respectively. The irrigation mechanism 4 comprises two support seats 401, the top of the two support seats 401 is fixedly connected with a shunt box 402, the outer side of the shunt box 402 is fixedly connected with a plurality of water guide pipes 403, and one end of one water outlet pipe 307 is fixedly connected with the outer side of the shunt box 402. In the irrigation mechanism 4, the shunt box 402 is designed with a special shunt structure, and a plurality of shunt channels are arranged in the shunt box 402, which can divide the water flowing from the water outlet pipe 307 into uniform multiple water flows and convey the water flows to the corresponding area of the wheat plants through the multiple water guide pipes 403. The outlet direction and angle of the water guide pipe 403 are optimized, so that the water flow can be irrigated on the roots and leaves of the wheat plants with appropriate force and range, and it is ensured that the water is fully absorbed by the plants. The drip irrigation mechanism 5 comprises a support frame 501, the top of the support frame 501 is fixedly connected with a connecting block 502, the bottom of the connecting block 502 is fixedly connected with a plurality of water dripping cones 503, the outer side of the connecting block 502 is fixedly connected with a plurality of drainage cones 504, the drainage cones 504 are located below the corresponding water dripping cones 503, the top of the connecting block 502 is fixedly connected with a water storage tank 505, a plurality of water leakage holes 506 are formed in the water storage tank 505, the water leakage holes 506 are located directly above the corresponding water dripping cones 503, and one end of the other water outlet pipe 307 is fixedly connected with the outer side of the water storage tank 505. The capacity of the water storage tank 505 and the size and number of the water leakage holes 506 of the drip irrigation mechanism 5 are accurately calculated and verified through experiments. The water storage tank 505 can store a certain amount of water, and the water is slowly dripped on the water dripping cone 503 through the permeation of the water leakage hole 506, the conical structure of the water dripping cone 503 can make the water droplets drop at a stable speed after gathering, and then the water is guided to the soil around the roots of another row of wheat plants through the recessed channel of the drainage cone 504, so as to realize micro and continuous water supply and meet the requirements of different water supply modes in the test. The outer side of the base ring 1 is provided with two positioning mechanisms 6. The positioning mechanism 6 comprises an arc-shaped plate 601, an arc-shaped groove 602 is formed in the inner side of the arc-shaped plate 601, a movable column 603 is slidably connected to the inner side of the arc-shaped groove 602, a movable plate 604 is fixedly connected to the outer side of the movable column 603, a positioning cone 605 is slidably connected to the inner side of the movable plate 604, and a pressing block 606 is fixedly connected to the top of the positioning cone 605.Before the water and drought stress test is carried out, the positioning mechanism 6 needs to be adjusted according to the situation of the test site. The arc-shaped plate 601 is attached to the outside of the base ring 1, and by sliding the movable column 603 in the arc-shaped groove 602, the movable plate 604 is driven to move radially along the base ring 1 to find a relatively solid and suitable position for fixing. After the position is determined, press the pressing block 606 downward, so that the positioning cone 605 penetrates the movable plate 604 and is inserted into the soil, thereby stably fixing the base ring 1 in the test area, preventing it from shifting during the test process, and ensuring the accuracy and reliability of the test data. After the test is completed, the positioning mechanism 6 can be operated in reverse, the pressing block 606 is pulled upward, the positioning cone 605 is pulled out of the soil, and then the movable column 603 is slid to retract the movable plate 604, making it easy to disassemble the base ring 1 from the test site, facilitating the storage and next use of the equipment.

[0025] Specifically, first, a piece of land is circled by the base ring 1, and the purpose of this step is to demarcate a relatively independent test area for water and drought stress test, so that the test can be carried out in a controllable environment. The base ring 1 plays the role of clear boundary, preventing external factors from interfering with the growth of wheat in the test area. Then, wheat is planted in the inner circle of the base ring 1 for water and drought stress test. During planting, ensure that the irrigation mechanism 4 and the drip irrigation mechanism 5 correspond to the two rows of wheat respectively. Such a layout can ensure that the two different water supply modes can accurately act on the corresponding wheat plants, providing basic conditions for subsequent tests. Start the electric push rod 304, which pushes the spring telescopic rod 305 to move, and then drives the piston to move in the installation cylinder 302. When the piston moves forward, the air inside the installation cylinder 302 is discharged. This operation forms a certain pressure difference in the installation cylinder 302, preparing for subsequent water absorption. Then, the spring telescopic rod 305 relies on its own elastic force to rebound and pull the piston back. At this time, due to the action of the pressure difference, the water in the water tank 7 is sucked into the inside of the installation cylinder 302 through the water inlet pipe 308. After the water enters the installation cylinder 302, it is transported to the flow splitter box 402 and the water reservoir 505 through two water outlet pipes 307 respectively. For the flow splitter box 402, its special flow splitting structure evenly splits the water to the multiple water guide pipes 403. The water flows from the water guide pipes 403 to the wheat plants, and this uniform irrigation method can provide sufficient water supply to the roots and leaves of the wheat plants, promoting the growth of the wheat. While on the side of the water reservoir 505, water penetrates through the water leakage hole 506 and drips onto the water dripping cone 503. The conical structure of the water dripping cone 503 causes the water droplets to gather and drip at a stable speed, and then through the recessed channel of the drainage cone 504, it is accurately dripped onto the other row of wheat plants. This drip irrigation method realizes the micro and continuous water supply, simulating the water supply situation under water and drought environment. In the same time, the two sides of the wheat respectively obtain less water through the irrigation mechanism 4 and the drip irrigation mechanism 5, and realize the difference between low frequency and small amount and high frequency and micro amount. This different water supply mode can be more conducive to diversified testing of the test, and study the growth response and adaptation mechanism of wheat under different water and drought stress conditions. In rainy days, the motor 206 can be started. The motor 206 drives one of the shafts to rotate, and since the two cylindrical gears 204 are meshed with each other, the other shaft will also rotate. In this way, the rotating block 202 drives the semicircular ring 203 to rotate, which can prop up the transparent film 208. After the transparent film 208 is propped up, the two elastic clamping blocks 209 are put on and the waterproof cloth 210 is stretched to cover the gap between the two semicircular rings 203. In this way, it can avoid external rainwater from entering the test area, providing a relatively stable growth environment for the wheat in the test area, ensuring that the water and drought stress test is not disturbed by rainwater, and ensuring the accuracy of the test results. The movable plate 604 can freely slide in the arc-shaped groove 602.Through this sliding mode, it is convenient to find the relatively solid place of the land. When the suitable position is found, the positioning cone 605 is inserted into the soil to fix the base ring 1. The insertion of the positioning cone 605 can enhance the stability of the base ring 1, prevent it from displacement during the test process, and ensure the independence of the test area and the reliability of the test data.

[0026] Working principle: first, a piece of land is circled by the base ring 1, and the wheat is planted in the inner circle of the land of the base ring 1 to perform the water and flood stress test, the irrigation mechanism 4 and the drip irrigation mechanism 5 correspond to two rows of wheat respectively, the electric push rod 304 is started to push the spring telescopic rod 305 to move to drive the piston to move, the air inside the mounting cylinder 302 is discharged, then the elastic force of the spring telescopic rod 305 rebounds to pull the piston back, and then the water in the water tank 7 is sucked into the inside of the mounting cylinder 302 through the water inlet pipe 308, and then is delivered to the flow distribution box 402 and the water storage pool 505 through two water outlet pipes 307 respectively, the water in the flow distribution box 402 is evenly distributed to the plurality of water guide pipes 403 to flow to the wheat plants, on the other hand, the water in the water storage pool 505 is infiltrated to the drip cone 503 through the water leakage hole 506 to drip, and then drips to the other row of wheat plants through the recessed channel of the drainage cone 504, so that the two rows of wheat are provided with less water in the same time, and the difference between low-frequency small amount acquisition and high-frequency micro amount acquisition is realized, which can be more conducive to diversified testing of the test; in addition, in rainy days, the motor 206 can be started to make the two cylindrical gears 204 rotate, and then the rotating block 202 drives the semicircular ring 203 to rotate, which can support the transparent film 208, and then the two elastic clamping blocks 209 are stretched to cover the gap between the two semicircular rings 203, so that the influence of external rainwater can be avoided; the movable plate 604 can be freely slid, the positioning cone 605 is inserted into the soil to fix the base ring 1.
