[0016] The present invention provides a method for using a simulated experimental device for soybean salt-alkali tolerance, comprising the following steps:

[0017] S1: Open the sowing door on the front of the sealed box, sow soybean seeds inside the sowing soil layer, and then close the sowing door;

[0018] S2: Control the control panel. According to the sowing time, input the time into the control panel and set the soybean simulation experiment time. Then the control panel will control the reduction motor to start. The reduction motor will drive the driving gear ring to rotate quickly, so that the driving gear ring rotates to the position corresponding to the input time.

[0019] S3: With the soybean sowing time set by the control panel, the reduction motor will continuously drive the driving gear ring to rotate with the time. When the driving gear ring is rotating, the second gear connected to one end of the driving gear ring connected to the saline-alkali spray tank will mesh with the driving gear ring for transmission, and drive itself to rotate through the driving gear ring. When the second gear is rotating, the energy storage lever on its top surface will slide against the transmission rod inside the saline-alkali spray tank, driving the transmission rod to slide inside the saline-alkali spray tank. With the sliding of the energy storage push plate, one end of the energy storage push plate will separate from the sealed water storage tank, and then the water inside the saline-alkali spray tank will enter the energy storage sealed tank. Then, with the rotation of the second gear, the energy storage lever will separate from the transmission rod, and the energy storage push plate will quickly rebound to the inside of the sealed water storage tank under the pull of the energy storage spring group, squeeze the water source inside the sealed water storage tank, and send the water source into the outlet pipe in a high-pressure manner, and spray it out through the atomizing nozzle;

[0020] At the same time, the arc-shaped rod connected to the top surface of the driving gear ring will drive the ring gear to rotate, drive the sunshine simulation lamp group to work, and drive the stepless transmission gearbox through the stepless driving wheel, so that the sunshine lamp can automatically adjust the brightness and temperature as the driving gear ring rotates. During the driving process of the stepless driving wheel, the fourth gear is synchronously driven to rotate, driving the transmission between the reciprocating transmission part and the reciprocating sliding part, so that the reciprocating sliding part drives the salt-alkali spray box to slide on the top surface of the sowing test bench;

[0021] During the sliding process of the saline-alkali water spray box, the soil water delivery box will be driven by the transmission push rod and the driving rack to slide on the top surface of the sowing test bench. When the saline-alkali water spray box slides to the outside of the sowing test bench and disengages from the second gear, the soil water delivery box will slide to the outside of the third gear, allowing the soil water delivery box and the driving gear ring to transmit the transmission. When the soil water delivery box and the third gear are transmitting, the energy storage part inside the soil water delivery box will drive the water source inside the soil water delivery box to be transported to the inside of the immersion rack, so as to transport water to the bottom of the sowing soil layer.

[0022] S4: During the experiment, saline-alkali water of different concentrations can be transported into the saline-alkali spray tank and the soil water supply tank according to the adaptability of soybeans, or saline-alkali water can be placed in the saline-alkali spray tank and clean water can be placed in the soil water supply tank.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention can realize the intermittent spraying of atomized saline-alkali water by the saline-alkali spray box on the top of the sowing soil layer by automatically adjusting the rotation speed of the driving gear ring. At the same time, by adjusting the daylight brightness of the sunshine simulation lamp group, the reciprocating movement of the saline-alkali spray box is synchronously controlled to drive the exchange transmission between the soil water supply box and the saline-alkali spray box, so that the sowing soil layer can automatically deliver saline-alkali water to the inside and upper part of the sowing soil layer during the day or at night, thereby improving the accuracy of the soybean salt-alkali tolerance sowing test results.

[0025] 2. The present invention is provided with a closed warehouse which is completely sealed from the outside world. The cooperation of the sunlight simulation lamp group and the saline-alkali spray box and other structures can realize the complete simulation of the soybean sowing environment. At the same time, the sowing of soybeans can be facilitated by the sowing warehouse door, and the sealing of the inside of the closed box. The control panel can automatically control the driving speed of the driving gear ring and the operation control of various internal functional modules. The transparent warehouse roof can observe the growth status of soybeans from the outside world during the experiment.

[0026] 3. The meshing drive of the driving gear ring and the reduction motor of the present invention can realize the function of controlling the rotation speed of the driving gear ring according to the time of day and night, and the driving gear ring synchronously drives the switch of the saline-alkali spray box and the sunlight simulation lamp group, and can control the brightness and heat of the sunlight simulation lamp group by stepless speed change during the day, spray atomized saline-alkali liquid on the sowing soil layer within a fixed time, ensure the humidity inside the closed box, and realize the simulation of various states of the saline-alkali environment for soybean sowing.

[0027] 4. The transmission between the saline-alkali spray box and the driving gear ring of the present invention drives the transmission of the energy storage part through the driving gear ring, so that the inside of the saline-alkali spray box has sufficient power to spray the fixed saline-alkali water onto the upper part of the sowing soil layer, and the driving gear ring can intermittently drive the saline-alkali spray box in a cyclic manner within a fixed time to spray the saline-alkali water.

[0028] 5. The present invention is provided with a stepless gearbox inside the sunlight simulation lamp group, which can drive the current inside the stepless gearbox to change from large to small and then to large again by driving the gear ring to rotate over time, so that the sunlight lamp connected to the sunlight wire can change the brightness and temperature inside the closed box over time, thereby realizing the simulated change of sunlight inside the closed box.

[0029] 6. The present invention has a reciprocating transmission part in transmission connection below the sunlight simulation lamp group, which is in transmission connection with the reciprocating sliding parts on both sides of the saline-alkali spray box, so that the saline-alkali spray box can be connected to the driving gear ring during the day, while the transmission connection function is lost at night, so that the saline-alkali spray box can spray saline-alkali water on the sowing soil layer during the day and remain stationary at night.

[0030] 7. In the present invention, a soil water delivery box is transmission-connected on one side adjacent to the saline-alkali water spray box connected to the driving gear ring. The soil water delivery box can directly and evenly deliver saline-alkali water to the inside of the sowing soil layer, thereby improving the bottom wetness of the sowing soil layer, thereby improving the simulation accuracy of soil moisture. At the same time, the soil water delivery box and the saline-alkali water spray box are transmission-connected. When the reciprocating transmission part drives the saline-alkali water spray box to stand still, the driving water delivery box can be transmission-connected to the driving gear ring, so that the soil water delivery box can deliver saline-alkali water or clean water to the bottom of the sowing soil layer at night.

[0070] Example 5

[0071] The simulated experimental equipment for soybean salt-alkali tolerance provided in Example 1, 2, 3 or 4 is further optimized. Specifically, Figure 1-Figure 12As shown, an energy storage part 51 is installed inside the soil water delivery box 7, and the transmission rod 56 inside the energy storage part 51 is slidably connected to the energy storage lever 45 connected to the top surface of the third gear 44. A screw 71 is fixed to the side of the soil water delivery box 7 away from the driving gear ring 4, and a screw transmission gear 72 with threaded engagement is sleeved on the outer side of the screw 71. The outer surface of the screw transmission gear 72 is meshed with the gear block on the top surface of the driving rack 505 for transmission. The screw transmission gear 72 is limited to rotate inside the closed box 2, and a water rack water delivery pipe 73 is connected to the inside of the energy storage part 51, and the far end of the water rack water delivery pipe 73 is connected to the inside of the immersion rack 31.

[0072] The driving gear ring 4 is connected to the side adjacent to the saline-alkali water spray box 5, and is transmission-connected to a soil water delivery box 7. The soil water delivery box 7 can directly and evenly deliver saline-alkali water to the inside of the sowing soil layer 3, thereby improving the bottom wetness of the sowing soil layer 3, thereby improving the simulation accuracy of soil moisture.

[0073] See also Figure 1-Figure 12 The embodiment of the present invention provides a method for using a soybean salt-alkali tolerance simulation experiment device, and the method for using the soybean salt-alkali tolerance simulation experiment device comprises the following steps:

[0074] S1: Open the sowing door 21 on the front of the sealed box 2, sow soybean seeds inside the sowing soil layer 3, and then close the sowing door 21;

[0075] S2: Control the control panel 22, input the time into the control panel 22 according to the sowing time, and set the soybean simulation experiment time, then the control panel 22 will control the reduction motor 41 to start, the reduction motor 41 will drive the driving gear ring 4 to rotate quickly, so that the driving gear ring 4 rotates to the position corresponding to the input time;

[0076] S3: As the soybean sowing time is set by the control panel 22, the reduction motor 41 will continuously drive the driving gear ring 4 to rotate with the time. When the driving gear ring 4 is rotating, the second gear 43 connected to one end of the driving gear ring 4 connected to the saline-alkali spray tank 5 will mesh with the driving gear ring 4 and drive itself to rotate through the driving gear ring 4. When the second gear 43 is rotating, the energy storage lever 45 on the top surface thereof will slide against the transmission rod 56 inside the saline-alkali spray tank 5, driving the transmission rod 56 to slide inside the saline-alkali spray tank 5. Move, with the sliding of the energy storage push plate 54, one end of the energy storage push plate 54 will be separated from the sealed water storage tank 53, and then the water inside the saline-alkali spray water box 5 will enter the energy storage sealed tank 52, and then with the rotation of the second gear 43, the energy storage lever 45 will be separated from the transmission rod 56, and the energy storage push plate 54 will be pulled by the energy storage spring group 57, and quickly rebound to the inside of the sealed water storage tank 53, squeeze the water source inside the sealed water storage tank 53, and send the water source into the outlet pipe 58 in a high-pressure manner, and spray it out through the atomizing nozzle 59;

[0077] At the same time, the arc rod 46 connected to the top surface of the driving gear ring 4 will drive the ring gear 47 to rotate, drive the sunlight simulation lamp group 6 to work, and drive the stepless transmission 62 through the stepless driving wheel 61, so that the sunlight lamp rotates with the driving gear ring 4, automatically adjusts the brightness and temperature, and synchronously drives the fourth gear 64 to rotate during the driving process of the stepless driving wheel 61, drives the transmission between the reciprocating transmission part 60 and the reciprocating sliding part 50, so that the reciprocating sliding part 50 drives the salt-alkali spray box 5 to slide on the top surface of the sowing test bench 1;

[0078] During the sliding process of the saline-alkali water spray box 5, the soil water delivery box 7 will be driven by the transmission push rod 504 and the driving rack 505 to slide on the top surface of the sowing test bench 1. When the saline-alkali water spray box 5 slides to the outside of the sowing test bench 1 and is disengaged from the second gear 43, the soil water delivery box 7 will slide to the outside of the third gear 44, so that the soil water delivery box 7 and the driving gear ring 4 are transmitted. When the soil water delivery box 7 and the third gear 44 are transmitted, the energy storage part 51 inside the soil water delivery box 7 will drive the water source inside the soil water delivery box 7 to be transported to the inside of the immersion rack 31, and the water source is transported to the bottom of the sowing soil layer 3;

[0079] S4: During the experiment, saline-alkali water of different concentrations can be transported into the saline-alkali spray tank 5 and the soil water supply tank 7 according to the adaptability of soybeans, or saline-alkali water can be placed in the saline-alkali spray tank 5 and clean water can be placed in the soil water supply tank 7.

[0080] Working steps:

[0081] After the soybean seeds are sown into the sowing soil layer 3, the sealed box 2 is in a sealed closed state, and the first gear 42 at the output end of the reduction motor 41 is driven by the reduction motor 41 to drive the driving gear ring 4 to rotate, and the driving gear ring 4 synchronously drives the arc rod 46, the second gear 43, and the third gear 44 to rotate, and the energy storage lever 45 on the top surface of the second gear 43 will be transmitted to the energy storage part 51 inside the salt-alkali spray box 5 as the second gear 43 rotates, and the transmission rod 56 inside the energy storage part 51 will conflict with the energy storage lever 45 for transmission, and as the second gear 43 rotates, the energy storage lever 45 on the top surface of the second gear 43 will be transmitted to the energy storage part 51 inside the salt-alkali spray box 5, and the transmission rod 56 inside the energy storage part 51 will be transmitted in friction with the energy storage lever 45. When the wheel 43 rotates, the energy storage lever 45 will push the transmission rod 56 to move, and the transmission rod 56 will drive the transmission bar 55 to push the energy storage push plate 54 to slide. During the sliding of the energy storage push plate 54, the energy storage spring group 57 will be subjected to tension to provide tension energy. When the energy storage lever 45 is rotated to separate from the transmission rod 56, the energy storage spring group 57 will provide tension to pull the energy storage push plate 54 into the sealed water storage tank 53, providing high-strength tension to squeeze the water source, transport it into the outlet pipe 58, and spray it above the sowing soil layer 3 through the atomizing nozzle 59.

[0082] It should be noted that the energy storage spring group 57 is a plurality of tension springs, which can provide a high-strength reset tension for the energy storage push plate 54 and push the water source inside the sealed water storage tank 53 with high pressure.

[0083] The rotation of the arc rod 46 will drive the ring gear 47 to rotate, and the rotation of the ring gear 47 will drive the stepless driving wheel 61 to rotate. The rotation of the stepless driving wheel 61 drives the internal drive of the stepless gearbox 62, so that the stepless gearbox 62 can gradually control the current inside the sunlight wire 63, so that the sunlight lamp connected to the far end of the sunlight wire 63 can gradually change from dark to bright, and then from bright to dark, completing the simulation of day and night inside the closed box 2.

[0084] It should be noted that the continuously variable transmission 62 gradually increases the current of the fluorescent lamp through stepless rotation, so that the temperature and brightness of the fluorescent lamp gradually increase. When the current reaches the maximum, the current will gradually decrease with continuous rotation until the fluorescent lamp is completely turned off. When the fluorescent lamp is turned off, a low current will be transmitted for a limited time in the continuously variable transmission 62, so that the fluorescent lamp is in the state of minimum lighting at night. This state is adjustable, and the time of this state can be adjusted, so as to achieve a night simulation state inside the closed box 2.

[0085] During the rotation of the stepless driving wheel 61, the fourth gear 64 is synchronously driven to rotate. The fourth gear 64 drives the fifth gear 601 inside the reciprocating transmission part 60 to rotate through the first transmission belt 65. The rotation of the fifth gear 601 drives the sixth gear 602. The seventh gear 603 rotates, and the second transmission belt 604 and the third transmission belt 605 are respectively sleeved on the outside of the sixth gear 602 and the seventh gear 603. The second transmission belt 604 and the third transmission belt 605 drive the eighth gear 606 and the ninth gear 607 to rotate. The eighth gear 606 and the ninth gear 607 synchronously drive the transmission cam 501 inside the reciprocating sliding part 50 to rotate. When the transmission cam 501 rotates, it drives the cam transmission rod 502 to reciprocate and drive the salt-alkali spray box 5 to slide on the surface of the sowing test bench 1.

[0086] During the sliding process of the saline-alkali spraying box 5, the transmission push rod 504 is driven to slide, and during the sliding process of the transmission push rod 504, the driving function rack is driven to slide, and the tooth block at the far end of the driving rack 505 drives the screw transmission gear 72 on the back of the soil water delivery box 7 to rotate, and the rotation of the screw transmission gear 72 drives the screw 71 to apply thrust to the soil water delivery box 7, pushing the soil water delivery box 7 to slide toward one side of the driving gear ring 4. After the soil water delivery box 7 slides to one side, the energy storage lever 45 above the third gear 44 will be transmitted with the energy storage part 51 inside the soil water delivery box 7, driving the energy storage part 51 to apply pressure to the water source inside the soil water delivery box 7, and sending the water source into the immersion rack 31 through the water rack water delivery pipe 73.

[0087] When the transmission cam 501 of the reciprocating sliding part 50 rotates to a far distance and rotates inward, a pulling force is applied to the saline-alkali spray box 5, pulling the saline-alkali spray box 5 to slide toward the position of the driving gear ring 4, thereby completing the transmission of the saline-alkali spray box 5 and the driving gear ring 4. During the inward sliding of the saline-alkali spray box 5, the driving rack 505 pulls the screw transmission gear 72 to rotate, driving the screw 71 to apply a pulling force to the soil water delivery box 7, pulling the soil water delivery box 7 to slide to the outside of the driving gear ring 4, completing the transmission separation exchange between the soil water delivery box 7 and the driving gear ring 4 in the daytime state.

[0088] It should be noted that: in the present invention, all transmission components and driving components are located inside the closed box 2, the gear transmission has a rotation position limit, and the sliding drive components have a sliding space.

[0089] The use process of the soybean salt-alkali tolerance simulation experiment equipment and method provided by the present invention is as follows:

[0090] Open the sowing chamber door 21, plant the soybean seeds to be sown in the sowing soil layer 3, then close the sowing chamber door 21, control the operation panel 22, input the required planting time, then input the planting time according to the time of the day when planting, start the equipment, and the reduction motor 41 will drive the drive gear ring 4 to work, and adjust the state and environment inside the closed box 2 to the same state as the input planting time. Then, as the drive gear ring 4 is driven for 24 hours, the drive gear ring 4 will drive the saline-alkali spray box 5 and the sunlight simulation lamp group 6 to work, spray saline-alkali water on the sowing soil layer 3, and adjust the room temperature and brightness inside the closed box 2.

[0091] At night, as the reciprocating transmission part 60 below the sunlight simulation lamp group 6 is driven, the reciprocating sliding part 50 will drive the saline-alkali spray box 5 to slide to the far side of the driving gear ring 4, so that the saline-alkali spray box 5 is separated from the energy storage lever 45 of the second gear 43 and disengaged from the transmission. During the sliding of the saline-alkali spray box 5, the transmission push rod 504 and the driving rack 505 will drive the screw transmission gear 72 on the back of the soil water delivery box 7 to rotate, and the screw transmission gear 72 itself is limited, so the screw 71 meshing with the screw transmission gear 72 will push the soil water delivery box 7 to slide, so that the energy storage part 51 inside the soil water delivery box 7 is connected to the energy storage lever 45 above the third gear 44, so that the sowing soil layer 3 can transport water to the inner bottom at night to maintain the soil moisture in the lower part of the sowing soil layer 3.
