[0022] 3. The soilless cultivation device for astragalus seedlings controls the first solenoid valve to be closed through a controller, obtains the position of the locator in real time through the controller, and judges the water surface position. When it reaches the set position, the first solenoid valve is controlled to be opened through the controller, and the flow control valve controls the rate at which water flows from the second cavity to the first cavity to be the same as the pumping rate of the first pumping pipe, thereby effectively preventing the water level in the cultivation box from dropping and affecting the cultivation effect of astragalus.

[0033] A purification box 301 is fixedly connected to one side of the cultivation box 1 close to the water pump 3, a net bucket 302 is fixedly connected inside the purification box 301, the lower end of the second pumping pipe 304 is connected to the inner side of the net bucket 302, and a first pumping pipe 303 is arranged between the purification box 301 and the cultivation box 1.

[0034] The connection box 2 is provided with a plurality of square grooves 201 , and a plurality of cultivation boxes 202 are provided in the square grooves 201 .

[0035] When soilless cultivation of Astragalus membranaceus in the seedling stage is performed, water containing nutrient solution is added to the cultivation box 1, and the Astragalus membranaceus is placed in the cultivation box 202. During cultivation, a certain gap is left between the upper end of the root of the Astragalus membranaceus and the water surface so that it can breathe with the water surface.

[0036] The water pump 3 is turned on by the controller 109, and the water pump 3 draws water from the cultivation box 1, and then transports the water to the first distribution pipe 305, and sprays the water through multiple first nozzles 306 to clean the Astragalus roots exposed above the water surface, thereby effectively preventing the roots exposed above the water surface from being adhered to excessive impurities and causing them to rot. At the same time, the roots can be effectively replenished with water in all directions, effectively improving the cultivation effect of the Astragalus.

[0037] When the water pump 3 is pumping water, the water in the cultivation box 1 enters the purification box 301 through the first pumping pipe 303, and the impurities in the water are filtered through the net bucket 302 in the purification box 301, thereby effectively filtering the impurities in the water and preventing the impurities in the water from causing the root system of the Astragalus to rot.

[0041] The controller 109 timing controls the second solenoid valve 106 to open for a period of time and then close. When it is opened, part of the water in the second cavity 108 flows into the first cavity 107. At this time, the water level in the second cavity 108 drops, so that the roots of the Astragalus are completely exposed to the air. At this time, the water sprayed by the first nozzle 306 comprehensively cleans the roots of the Astragalus, thereby effectively preventing the roots of the Astragalus in the water from being attached to impurities and causing them to rot.

[0042] When the second solenoid valve 106 is closed, the controller 109 controls the first solenoid valve 103 to close, and the position of the locator 402 is obtained in real time through the controller 109 to judge the water surface position. When it reaches the set position, the first solenoid valve 103 is controlled to open through the controller 109, and the flow control valve 104 controls the flow rate of water from the second cavity 108 to the first cavity 107 to be the same as the pumping rate of the first pumping pipe 303, thereby effectively preventing the water level in the cultivation box 1 from dropping and affecting the cultivation effect of Astragalus.
