The arc slide rail 11 and the limit slide 12 play a sliding limit role in the rotating shaft 63, and the circuit breaker 14 is controlled to cut off the power to the electromagnet 15, so that the electromagnet 15 loses the electromagnetic adsorption force on the positioning magnet 16. Then, the rotating shaft 63 first drives the bent arm 66 to adjust the angle in the direction of the seed soaking box 2 , and the angle sensor 13 monitors the adjustment angle of the curved arm 66 in real time. After the electric cylinder 67 on the curved arm 66 and the breeding box 72 on the bracket 71 reach the top of the soaking box 2, since the curved arm 66 is rotatably connected to the electric cylinder 67 through the mounting piece, the breeding box 72 that reaches the top of the soaking box 2 automatically balances according to its own weight, and then controls the electric cylinder 67 to open and drive the breeding box 72 to move down into the soaking box 2 through the bracket 71, and makes the pumpkin rootstock seedling rods or seeds placed in advance in the breeding grid 73 immersed in the soaking liquid in the soaking box 2. The soaking liquid reaches the pumpkin stock seedling rod or seed area in the breeding grid 73 through the intercommunication groove 74, and fully immerses it. After the pumpkin stock seedling rod or seed immersed in the soaking liquid in the soaking box 2 is soaked, similarly, the pumpkin stock seedling rod or seed in the breeding box 72 after soaking is sent to the sterilization box 3, and the sterilization liquid in the sterilization box 3 sterilizes the pumpkin stock seedling rod or seed after soaking. After the pumpkin stock seedling rod or seed is soaked and sterilized, it is reset to the top of the screening box 1 and paused, and the upper cover 75 is removed. After the two lower sealing plates 77 in the guide rail edge 76 are retained, the pumpkin stock seedling stems or seeds in the breeding box 72 after soaking and sterilization are brought into the screening box 1, and the saline-alkali solution with nutrient solution therein is submerged to two-thirds of the breeding box 72, the double-headed motor 61 is first controlled to pause, and then the first electric push rod 64 is controlled to close and drive the driven circular gear 65 to move backward and disengage from the meshing portion of the driving circular gear 62 to the initial position, and under the nourishment of the nutrient solution, the pumpkin stock seedling stems or seeds in the breeding box 72 germinate and grow in the saline-alkali solution in the screening box 1;

[0054] During the period when the pumpkin rootstock seedling stems or seeds successively arrive at the saline-alkali solution, seed soaking solution and sterilizing solution in the screening box 1, the seed soaking box 2 and the sterilizing box 3, the double-headed motor 61 drives the main synchronous wheel 81 to rotate, and the main synchronous wheel 81 drives the exhaust fans 83 on the two sets of auxiliary synchronous wheels 82 to rotate synchronously in the two sets of sealing frames 5 through the synchronous belt, and after the wind pressure and wind force are generated in the two sets of sealing frames 5, the first-level pressurizing pipes 85 on the two sets of wind collecting heads 84 are pressurized and supplied to the two sets of three-way valves 86, and then The two sets of three-way valves 86 are respectively supplied into the soaking liquid and the sterilizing liquid in the soaking box 2 and the sterilizing box 3 through the two sets of aeration heads 91, and the soaking liquid and the sterilizing liquid in the soaking box 2 and the sterilizing box 3 are aerated, so that the aerated soaking liquid and the sterilizing liquid successively contact the pumpkin rootstock seedling stems or seeds in place, completing the effective soaking and sterilization treatment of the pumpkin rootstock seedling stems or seeds, and the two sets of pressure sensors 92 monitor the wind pressure in the two sets of three-way valves 86 in real time. At the same time, the wind pressure and wind force in the two groups of three-way valves 86 are pressurized again through two secondary pressure pipes 93, and then centrally supplied to the four-way valve 94. At the same time, the small integrated cold and hot machine 95 is controlled to start in advance and provide a cold source or a hot source according to the current ambient temperature requirements. The cold source or the hot source provided by the small integrated cold and hot machine 95 is also supplied to the four-way valve 94 and merged with the wind pressure and wind force to form a pressurized cold source or hot source, and finally supplied to the saline-alkali solution with nutrient solution in the screening box 1 through the aeration pipe 96, so that Aeration disturbance, and full contact and absorption with the pumpkin stock seedling pole or seed, while also cooling or heating it, so that the saline-alkali solution with nutrient solution in the screening box 1 is always maintained at a growth temperature suitable for the pumpkin stock seedling pole or seed, under the nourishment of the nutrient solution, the pumpkin stock seedling pole or seed is germinated to accelerate its growth rate, and after the pumpkin stock seedling pole or seed germinates and grows, its survival rate is calculated, and the current pumpkin stock seedling pole or seed salt and alkali tolerance screening result can be known.

[0055] It should be noted that the specific models and specifications of the double-headed motor 61, electric push rod, electric cylinder 67 and small hot and cold integrated machine 95 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0056] The power supply circuits of the double-headed motor 61, the electric push rod, the electric cylinder 67, the small integrated cold and hot machine 95, and various valves and sensors are clear to those skilled in the art and will not be described in detail here.
