Description

Technical Field

[0001] This utility model relates to the technical field of plant physiological experimental equipment, and in particular to a gradient concentration saline slow-release irrigation component for plant salt stress resistance experiments. Background Technology

[0002] In plant salt stress experiments, accurately constructing a gradient salt environment and achieving stable irrigation are core requirements. Existing technologies suffer from three major drawbacks: First, most irrigation devices require frequent manual replacement of the salt solution to create a concentration gradient, which is cumbersome and prone to concentration fluctuations, affecting experimental repeatability. Second, salt application is mostly instantaneous, failing to simulate the slow accumulation of salt in natural saline-alkali environments, resulting in significant deviations from actual stress scenarios. Third, some gradient irrigation systems can only achieve single-dimensional concentration control and lack real-time monitoring and feedback mechanisms, making it difficult to guarantee the stability and uniformity of salt concentration in each experimental unit. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a gradient concentration saline slow-release irrigation component for plant salt stress resistance experiments.

[0004] This utility model is achieved using the following technical solution: a gradient concentration saline slow-release irrigation component for plant salt stress resistance experiments, comprising an experimental platform, a loading component, and an irrigation component; the experimental platform has four legs at its lower corners, and a loading component is located on the upper rear side of the experimental platform; the loading component includes a support rod, a collar, a bracket, a baffle, a rotating shaft, a stop pawl, and a limiting block; the upper end of the support rod is fitted with a collar, the side end of the collar is fixedly connected to the bracket, the right side of the bracket is movably connected to the baffle via a rotating shaft, the top right side of the bracket has an assembly groove, the front and rear ends of the assembly groove are rotatably connected to stop pawls, the side ends of the stop pawls are fixedly connected to the limiting block, and the lower end of the stop pawls is engaged with the top end of the baffle.

[0005] With the above technical solution, the collar can slide up and down the support rod, thereby adjusting the height of the bracket to suit the operator's habits. The baffle is used to fix the slow-release salt cup. The baffle can be firmly locked to the bracket by the pawl and the limiting block. When it is necessary to remove the slow-release salt cup, the pawl can be pushed into the assembly slot, thereby opening the baffle.

[0006] As a further improvement to the above solution, the irrigation component includes a water storage tank, a water pump, a drain pipe, a diverter pipe, and a drip head. The water storage tank is fixedly connected to the rear end of the experimental platform. The water pump is installed at the upper end of the water storage tank. The input end of the water pump is connected to the inside of the water storage tank. The output end of the water pump is connected to four drain pipes. The end of the drain pipe is connected to a diverter pipe through a diverter valve. The end of the diverter pipe is fixedly connected to a drip head.

[0007] The above technical solution allows the brine from the storage tank to be transferred to the pouring pipe via a water pump. Then, the brine content inside different pouring pipes is made inconsistent by a diversion valve, and the drip head drips the brine into the slow-release salt supply cup.

[0008] As a further improvement to the above solution, the irrigation assembly also includes a glass rotor flow meter and an outlet pipe. The lower end of the bracket is provided with a glass rotor flow meter, and the lower end of the glass rotor flow meter is connected to the outlet pipe.

[0009] Through the above technical solution, the glass rotor flowmeter can monitor the content and concentration of brine, and when a certain concentration is reached, it is transmitted to the porous dropper through the outlet pipe.

[0010] As a further improvement to the above solution, the irrigation component also includes a support plate and a porous drip tube. The upper end of the experimental platform is provided with a support plate, the upper end of the support plate supports the liquid outlet pipe, and the end of the liquid outlet pipe is connected to the porous drip tube.

[0011] Using the above technical solution, the porous dropper can make the solution evenly penetrate to the surface of the culture dish.

[0012] As a further improvement to the above solution, the irrigation assembly also includes a slow-release salt supply cup, which is placed inside the support. The bottom of the slow-release salt supply cup has a magnetic stir bar and an electromagnetic stirrer.

[0013] Through the above technical solution, different doses of salt particles are added to the inside of the four slow-release salt supply cups. The salt water and salt particles are mixed through the dropper, and the salt water and salt particles are fully blended into a salt water of a predetermined concentration through the electromagnetic stirrer.

[0014] As a further improvement to the above scheme, the front end of the experimental platform is provided with four sets of petri dishes, the bottom of the petri dishes is provided with a water permeable trough, the end of the water permeable trough is collected into a water collection tank, and the side end of the petri dishes is provided with a saline monitoring sensor.

[0015] Through the above technical solution, the permeable tank can avoid cross-contamination of salt solutions inside the petri dish, and the saline monitoring sensor can observe the saline concentration in the petri dish, which is convenient for subsequent control.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting up a loading component, allows the collar to slide up and down the support rod, thereby adjusting the height of the bracket to suit the operator's habits. The baffle is used to fix the slow-release salt cup, and the baffle can be firmly locked to the bracket by the stop claw and the limiting block. When it is necessary to remove the slow-release salt cup, the stop claw can be pushed into the assembly slot, thereby opening the baffle.

A diversion valve ensures that the brine content varies between different dispensing pipes. A drip head dispenses brine into a slow-release salt supply cup. A glass rotor flow meter monitors the brine content and concentration. When a certain concentration is reached, the brine is transferred to a multi-hole drip tube through an outlet pipe.

[0022] The collar 22 can slide up and down the support rod 21, thereby adjusting the height of the bracket 23 to suit the operator's habits. The baffle 24 is used to fix the slow-release salt cup 310. The baffle 24 can be firmly locked to the bracket 23 by the pawl 26 and the limiting block 27. When it is necessary to remove the slow-release salt cup 310, the pawl 26 can be pushed into the assembly slot, thereby opening the baffle 24.

[0023] The irrigation assembly 3 includes a water storage tank 31, a water pump 32, a drain pipe 33, a diverter pipe 34, and a drip head 35. The water storage tank 31 is fixedly connected to the rear end of the experimental platform 1. The water pump 32 is installed at the upper end of the water storage tank 31. The input end of the water pump 32 is connected to the inside of the water storage tank 31. The output end of the water pump 32 is connected to four drain pipes 33. The end of the drain pipe 33 is connected to the diverter pipe 34 through a diverter valve. The end of the diverter pipe 34 is fixedly connected to the drip head 35.

[0024] The brine from the water storage tank 31 can be transferred to the pouring pipe 33 by the suction pump 32, and the brine content inside the different diversion pipes 34 can be made inconsistent by the diversion valve. The drip head 35 drips the brine into the slow-release salt supply cup 310.

[0025] The irrigation assembly 3 also includes a glass rotor flow meter 36 and an outlet pipe 37. The lower end of the bracket 23 is equipped with a glass rotor flow meter 36, and the lower end of the glass rotor flow meter 36 is connected to the outlet pipe 37.

[0026] The glass rotor flowmeter 36 can monitor the content and concentration of saline solution. When a certain concentration is reached, the solution is transferred to the porous dropper 39 through the outlet pipe 37.

[0027] The irrigation component 3 also includes a support plate 38 and a porous drip tube 39. The upper end of the experimental platform 1 is provided with a support plate 38, the upper end of the support plate 38 supports the liquid outlet pipe 37, and the end of the liquid outlet pipe 37 is connected to the porous drip tube 39.

[0028] The porous dropper 39 allows the solution to penetrate evenly onto the surface of the petri dish 6.

[0029] The irrigation assembly 3 also includes a slow-release salt supply cup 310, which is placed inside the bracket 23. The slow-release salt supply cup 310 has a magnetic stir bar and an electromagnetic stirrer at its bottom.

[0030] The four slow-release salt cups 310 contain different amounts of salt particles. The salt water and salt particles are mixed through the dropper 35, and the salt water and salt particles are fully blended into a salt water of a predetermined concentration by an electromagnetic stirrer.

The end of the water permeable trough 4 is collected into the water collection and recovery trough 5. The side of the petri dishes 6 is equipped with a saline monitoring sensor 7. The water permeable trough 4 can avoid cross-contamination of the salt solution inside the petri dishes 6. The saline monitoring sensor 7 can observe the saline concentration of the petri dishes 6, which is convenient for subsequent control.

[0032] The implementation principle of a gradient concentration saline slow-release irrigation component for plant salt stress resistance experiments in this application embodiment is as follows: the collar 22 can slide up and down the support rod 21, thereby adjusting the height of the bracket 23 to suit the operator's habits. The baffle 24 is used to fix the slow-release salt supply cup 310. The baffle 24 can be firmly locked to the bracket 23 by the claw 26 and the limiting block 27. When it is necessary to remove the slow-release salt supply cup 310, the claw 26 can be pushed into the assembly groove, thereby opening the baffle 24. The water pump 32 can transfer the saline in the water storage tank 31 to the pouring pipe 33, and then the saline in the different diversion pipes 34 can be diverted by the diversion valve. Due to inconsistent content, the drip head 35 drips saline solution into the slow-release saline cup 310. The glass rotor flow meter 36 can monitor the content and concentration of saline solution. When a certain concentration is reached, it is transferred to the porous dropper 39 through the outlet pipe 37. The porous dropper 39 can make the solution evenly penetrate to the surface of the petri dish 6. Different doses of salt particles are added to the four slow-release saline cups 310 respectively. The saline solution and salt particles are mixed through the drip head 35. The saline solution and salt particles are fully mixed into a saline solution of a predetermined concentration by the electromagnetic stirrer. The permeable tank 4 can avoid cross-contamination of the salt solution inside the petri dish 6. The saline solution monitoring sensor 7 can observe the saline solution concentration of the petri dish 6 for easy subsequent adjustment.
