[0002] Salt-tolerant eggplant breeding refers to the scientific research and engineering practice of selecting new eggplant varieties that can grow normally in saline soils and maintain yield and quality through genetics, physiology, and modern biotechnology. Soil salinization is one of the major challenges facing global agriculture, especially in coastal mudflats, arid and semi-arid irrigated areas, and facility agriculture. Salt accumulation can damage soil structure, inhibit plant roots from absorbing water and nutrients, leading to stunted growth, reduced yields, and even crop failure in crops such as eggplant.

[0003] In existing technologies, the equipment for breeding salt tolerance in plants generally uses an incubator for cultivation. During the cultivation process, the corresponding salt concentration, salt type and other breeding conditions are adjusted as needed, and the salt tolerance of eggplants is confirmed based on the daily growth of the plants. However, the existing salt tolerance breeding equipment is not convenient for flexibly adjusting the salt concentration according to the needs and the salt distribution is not uniform enough, which affects the efficiency and accuracy of screening out truly salt-tolerant varieties.

[0039] 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.

[0040] like Figure 1-10 As shown, an easily controllable eggplant salt tolerance breeding device includes a culture box 7 with a door 2. Inside the culture box 7, multiple placement plates 6 are arranged vertically via support columns 5. A hydroponic box 3 is placed on the placement plate 6. A hydroponic basket 4 is detachably connected to the hydroponic box 3 via a fixing ring 41 and threads. The culture box 7 is equipped with a water mixing component that can be controlled according to different needs. The placement plate 6 is U-shaped and has multiple interconnected chambers 63 in the vertical plate. The multiple chambers 63 are connected to each other via water supply channels 61. Four limiting components 64 are set in the chambers 63. The chambers 63 are connected to the water mixing component. Multiple plugs 62 connected to the chambers 63 are set on the horizontal side of the placement plate 6.

[0041] The bottom of the hydroponic box 3 is provided with multiple sealing insertion holes 31 for sealing insertion with the plug 62. The inside of the hydroponic box 3 is provided with multiple mixing spray components 32 that communicate with the sealing insertion holes 31. The side of the hydroponic box 3 is provided with positioning holes 33 for the insertion of the limiting component 64. The limiting component 64 gradually inserts into or disengages from the positioning hole 33 as the pressure of the chamber 63 increases or decreases. When the limiting component 64 is fully inserted into the positioning hole 33, the sealing insertion hole 31 and the plug 62 are fitted and sealed.

[0042] In use, eggplants are planted in hydroponic baskets 4 and placed on placement plates 6 via hydroponic boxes 3. The connector 62 is then inserted into the sealed connector hole 31. The corresponding liquid parameters are then set according to requirements. The water mixing component mixes the corresponding salts, culture medium, and water according to these parameters. After mixing, the liquid enters chamber 63. The limiting component 64 is then gradually inserted into the positioning hole 33. During this process, the hydroponic box 3 gradually moves downwards, and the sealed connector hole 31 and connector 62 gradually seal and fit together. After the limiting component 64 is fully inserted into the positioning hole 33, the liquid in chamber 63 enters the mixing spray component 32 through the water inlet channel 3225 and connector 62. The mixing spray component 32 sprays out the corresponding liquid and stirs it to ensure uniform salt distribution and safe use.

[0043] The positioning hole 33 has a triangular cross-section with the hypotenuse at the bottom. The deepest part of the positioning hole 33 also has a cylindrical hole for the insertion and positioning of the limiting component 64.

[0044] Preferably, the pressure required for the limiting component 64 to be fully inserted into the positioning hole 33 is less than the minimum pressure required to start the mixing spray component 32, in order to avoid leakage.

[0045] In this embodiment, the mixing spray assembly 32 includes a fixed cylinder 321 that is threadedly connected to the hydroponic box 3, at least one rotary drive 322 disposed on the fixed cylinder 321, a centrifugal connecting member 323 disposed above the rotary drive 322, and a rotating bucket 324 located above the centrifugal connecting member 323. The fixed cylinder 321 is independently connected to the sealing insertion hole 31.

[0046] The rotary drive 322 is connected to the fixed cylinder 321 and the centrifugal connecting member 323 respectively, and the rotary drive 322 can gradually drive the rotating barrel 324 and the centrifugal connecting member 323 to rotate as the water pressure in the fixed cylinder 321 increases.

[0047] Centrifugal connector 323 connects to rotating barrel 324. Centrifugal connector 323 gradually opens when rotating so that rotating barrel 324 connects to fixed barrel 321. Multiple stirring plates 326 are provided on the outer circumferential side of rotating barrel 324. Stirring plates 326 are provided with drainage holes that communicate with rotating barrel 324.

[0048] The rotating barrel 324 at the top is not connected to the fixed barrel 321;

[0049] In use, the liquid enters the rotary drive 322 from the fixed cylinder 321. The rotary drive 322 rotates and drives the rotating barrel 324 and the centrifugal connecting member 323 to rotate. As the pressure increases, the centrifugal connecting member 323 increases in speed and opens. At this time, the liquid in the fixed cylinder 321 enters the rotating barrel 324 through the rotary drive 322 and the centrifugal connecting member 323 and is discharged. The rotating barrel 324 drives the stirring plate 326 to stir the liquid.

[0050] In this embodiment, the rotary drive 322 includes an intermediate cylinder 3224 rotatably connected to the inner wall of the fixed cylinder 321, a fan wheel 3223 coaxially fixed on the intermediate cylinder 3224, a fan blade 3221 fixed on the fan wheel 3223, and a water inlet channel 3225 opened on the fixed cylinder 321. The intermediate cylinder 3224 is fixedly connected to the centrifugal connector 323.

[0051] A circular groove is provided on the fixed cylinder 321, and the fan wheel 3223 is rotatably and sealed in the circular groove. A drive ring groove is also provided on one side of the outer circumference of the circular groove. The fan blade 3221 is located in the drive ring groove and can rotate around the center of the fan wheel 3223 along the drive ring groove.

[0052] The fixed cylinder 321 is also provided with a drainage channel 3222. The water inlet channel 3225 and the drainage channel 3222 are both connected to the drive ring groove to drive the fan blade 3221 to rotate. The drainage channel 3222 is connected to the outer circumferential side of the fixed cylinder 321, and the water inlet channel 3225 is connected to the fixed cylinder 321.

[0053] During use, the liquid in the fixed cylinder 321 drives the fan blade 3221 to move through the water inlet channel 3225, the fan wheel 3223 rotates and drives the intermediate cylinder 3224 to rotate, and then the liquid is discharged into the hydroponic box 3 through the drainage channel 3222.

[0054] The structure that rotates via water, fan blades 3221, and fan wheel 3223 is existing technology and can be adjusted according to the actual situation to ensure rotation drive.

[0055] In this embodiment, the centrifugal connecting member 323 includes a centrifugal disc 3234 rotatably connected to the fixed cylinder 321, two contact sealing blocks 3233 that are in contact with each other and sealed, and two centrifugal blocks 3231. The centrifugal disc 3234 is fixed coaxially with the intermediate cylinder 3224. The centrifugal disc 3234 has a sealing sliding cavity 3232 that is respectively connected to the intermediate cylinder 3224 and the rotating barrel 324. The contact sealing blocks 3233 and the sealing sliding cavity 3232 are in sliding contact and sealed.

[0056] The centrifuge disc 3234 has sliding grooves on both sides, and the centrifuge block 3231 is elastically slidably connected in the sliding groove. The centrifuge block 3231 is connected to the sealing block 3233.

[0057] During use, as the intermediate cylinder 3224 rotates, the centrifugal disc 3234 gradually rotates. During the rotation, the centrifugal block 3231 drives the two contact sealing blocks 3233 to move away from each other, so that the intermediate cylinder 3224 and the rotating drum 324 are connected. When the rotation speed decreases, the centrifugal force decreases, the centrifugal block 3231 elastically resets and pushes the two contact sealing blocks 3233 to contact and seal.

[0058] Elastic connections can be achieved using elastic components such as springs.

[0059] In this embodiment, the limiting component 64 includes a cylinder 643 fixed in the chamber 63, two limiting rings 641 fixed in the cylinder 643, a sealing plug 647 sealed and inserted in the cylinder 643 and located between the two limiting rings 641, a plug-in post 642 that can be inserted into the positioning hole 33, and a liquid inlet / outlet component. The sealing plug 647 is fixed to the plug-in post 642. The liquid inlet / outlet component drives the plug-in post 642 to extend and retract as the pressure in the chamber 63 changes. The cylinder 643 is connected to an airbag 646 fixed on the placement plate 6. The incubator 7 is made of transparent material at the location corresponding to the airbag 646.

[0060] When the pressure in chamber 63 increases, the liquid inlet and outlet assembly controls the liquid to enter the cylinder 643 and pushes the sealing plug 647 and the insertion post 642 out, so that the insertion post 642 is inserted into the positioning hole 33. When the pressure returns to normal, the insertion post 642 is still in the positioning hole 33 to ensure the positioning effect. When it needs to be removed, the liquid needs to be extracted by the water mixing assembly to make the chamber 63 form a negative pressure. At this time, under the action of the liquid inlet and outlet assembly, the sealing plug 647 and the insertion post 642 are disengaged from the positioning hole 33. Through the above process, the liquid left in the chamber 63 can be discharged to ensure the accuracy of subsequent salt adjustment.

[0061] During the salt adjustment process, some of the liquid in the hydroponic tank 3 enters through the mixing spray component to lower the overall water level and salt content, making it easier to adjust the salt content later.

[0062] In this embodiment, the liquid inlet and outlet assembly includes a guide cylinder 644 fixed in the chamber 63, a guide rod 645 sealed and inserted in the guide cylinder 644, an air extraction cylinder 648 sealed and inserted in the cylinder body 643 by a sealing element, a negative pressure cylinder 640 fixed in the chamber 63, and a sealing rod 649 sealed and inserted in the air extraction cylinder 648. The guide cylinder 644 has a hole on its side away from the air extraction cylinder 648, and the air extraction cylinder 648 has multiple round holes in the area located in the cylinder body 643. The air extraction cylinder 648 is elastically connected in the cylinder body 643 and connected to the guide rod 645.

[0063] The sealing rod 649 is elastically connected to the negative pressure cylinder 640 by a spring. The sealing rod 649 is slidably connected to the negative pressure cylinder 640 by a piston and cannot be separated from the negative pressure cylinder 640. The sealing rod 649 has a connecting hole that is axially downward. The connecting hole is not connected to the end of the sealing rod 649 located in the negative pressure cylinder 640. The circumferential side of the sealing rod 649 has an air extraction hole 6491 located in the air extraction cylinder 648. The air extraction hole 6491 is vertically offset from the circular hole.

[0064] During use, as the pressure in chamber 63 increases, the guide rod 645 moves along the guide cylinder 644 and pushes the suction cylinder 648 to move, so that the suction cylinder 648 and the cylinder 643 are no longer in sealed contact. At this time, liquid enters the cylinder 643, and the sealing plug 647 moves. When the pressure in chamber 63 returns to normal, the suction cylinder 648 elastically resets, and the sealing plug 647 remains stationary to ensure the positioning effect.

[0065] When the chamber 63 is under negative pressure, the guide rod 645 remains stationary, the sealing rod 649 moves so that the vent 6491 is disengaged from the vent cylinder 648, the liquid in the cylinder 643 is discharged through the round hole and the vent 6491, and the sealing plug 647 is reset.

[0066] In this embodiment, the plug connector 62 includes a plug sleeve 621 detachably connected to the placement plate 6 by a thread and a sealing contact ring 622 fixed on the plug sleeve 621. The sealing contact ring 622 contacts and seals with the sealing plug hole 31.

[0067] During use, the sealing contact ring 622 ensures a tight seal between the insertion hole and the insertion sleeve 621 to prevent leakage.

[0068] In this embodiment, a mixing chamber 73 is provided at the bottom of the hydroponic tank 3. The water mixing assembly includes a mixing device, a mixing peristaltic pump 71, a culture peristaltic pump 79, a connecting assembly, a brine tank 1, a tank A 75, and a tank B 76, all disposed within the mixing chamber 73. The mixing peristaltic pump 71 is connected to the connecting assembly, the mixing device, the tank A 75, and the tank B 76 via a control valve 74 and a pipeline, respectively. The culture peristaltic pump 79 is connected to the mixing device and a delivery pipeline 70. The delivery pipeline 70 is connected to the chamber 63. A sealed box 72 is provided inside the mixing chamber 73. The brine tank 1 is sealed and inserted into the sealed box 72 and connected to the connecting assembly.

[0069] When in use, water, nutrient solution and other liquids are put into the boxes A75 and B76 as needed. When it is necessary to output the mixed liquid, the corresponding liquid is drawn into the mixing equipment according to the ratio requirements and the saline concentration of the saline tank 1 for mixing. Under the action of the culture peristaltic pump 79 and the delivery pipe 70, the corresponding liquid is input into the chamber 63.

[0070] For the saline concentration, corresponding testing instruments can be added according to actual needs;

[0071] Preferably, the mixing equipment can also be connected to an external water storage tank via pipes and valves, allowing excess liquid to be discharged.

[0072] In this embodiment, the mixing device includes a mixing tank 77 fixed in the mixing chamber 73 and a stirring plate 78 rotatably connected in the mixing tank 77, and the stirring plate 78 is connected to a driving device.

[0073] The driving device is a motor, which is installed inside the incubator 7 (not shown in the figure);

[0074] In this embodiment, the communication component includes a plug plate 103 fixed in the mixing chamber 73, a communication cylinder 104 communicating with the brine tank 1, and a brine chamber 102 opened in the plug plate 103. The end of the communication cylinder 104 away from the brine tank 1 is located in the brine chamber 102 and cannot be removed from the brine chamber 102. The brine chamber 102 is connected to the mixing peristaltic pump 71. In use, the cooperation between the communication cylinder 104 and the brine chamber 102 ensures that the brine tank 1 can be connected when it is pulled out.
