[0002] Adding water and fertilizer and drying trays are important technical links in the floating seedling cultivation of flue-cured tobacco. Lack of water or fertilizer can easily lead to weak growth of tobacco seedlings. Therefore, it is necessary to pay attention to the water and fertilizer conditions in the seedling pool at all times, and add water and fertilizer in time to ensure the healthy growth of tobacco seedlings. In actual production, there are many seedling pools in the seedling greenhouse. At present, they are checked one by one and water and fertilizer are added one by one, which not only requires a lot of labor but also has low efficiency. Drying trays refers to the technical operation of separating the floating seedling trays from the water surface of the seedling pool. When the humidity of the floating seedling tray substrate is too high, it will restrict the growth of tobacco seedlings. Therefore, it is necessary to separate the floating seedling trays from the water surface for a period of time to achieve the purpose of reducing the humidity of the floating seedling trays and ensure the quality of seedling cultivation. The current operation of drying trays mainly involves using a large number of bamboo poles to lift the floating trays, etc. This is not only inefficient but also requires a lot of labor. It is necessary to conduct research and improvements on this. Utility Model Content

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] See also Figure 1 and Figure 2 In this embodiment, an intelligent water and fertilizer supply device for a seedling pond includes a seedling pond unit and a liquid supply unit.

[0026] The seedling pool unit includes a seedling pool frame 11 and a seedling pool 12 mounted on the upper portion of the seedling pool frame 11. The liquid supply unit includes a water source pool 21 and a nutrient solution pool 22 installed below the seedling pool 12. The water source pool 21 can be fixedly mounted at the lower portion of the seedling pool frame 11 or placed on the ground. The water source pool 21 is connected to the seedling pool 12 via a first water pump 23 and a liquid replenishment pipe 24. The nutrient solution pool 22 is connected to the seedling pool 12 via a second water pump 25 and a fertilizer replenishment pipe 26. The bottom of the seedling pool 12 is connected to the nutrient solution pool 22 via a drainage pipe 27. Solenoid valves 28 are provided on the liquid replenishment pipe 24, the fertilizer replenishment pipe 26, and the drainage pipe 27.

[0027] By positioning the seedling raising pool 12 frame 11 above the water source pool 21 and the nutrient solution pool 22, water can be added to the seedling raising pool 12 via the first water pump 23 and the liquid replenishment pipe 24, and fertilizer can be added to the seedling raising pool 12 via the second water pump 25 and the fertilizer replenishment pipe 26. This allows for timely addition of water and fertilizer to the seedling raising pool 12, ensuring the healthy growth of the tobacco seedlings. The nutrient solution in the seedling raising pool 12 is returned to the nutrient solution pool 22 via the drainage pipe 27, allowing the floating seedling raising trays to be dried directly in the seedling raising pool 12. After drying, the second water pump 25 and the fertilizer replenishment pipe 26 can pump the fertilizer water back into the seedling raising pool 12 for seedling cultivation. The entire process does not require manual operation to lift the floating seedling raising trays for drying.

[0028] For ease of operation, the device also includes a detection unit and a control unit. The detection unit includes a first water level sensor 31 and a first EC sensor 32 installed within the nursery pool 12, respectively detecting the water level and the fertilizer concentration in the nutrient solution. The control unit includes a controller 41, which is electrically connected to the first water level sensor 31, the first EC sensor 32, the first water pump 23, the second water pump 25, and the solenoid valve 28. After controller 41 determines the water level and fertilizer concentration in the nursery pool 12, it can add water, add fertilizer, and drain water from the nursery pool 12 according to a preset program. When adding water, the first water pump 23 and the solenoid valve 28 on the refill pipe 24 remain open, while the remaining pipes and the solenoid valve 28 remain closed. When adding fertilizer, the second water pump 25 and the solenoid valve 28 on the fertilizer refill pipe 26 remain open, while the remaining pipes and the solenoid valve 28 remain closed. When draining water, the solenoid valve 28 on the drain pipe 27 remains open, while the remaining pipes and the solenoid valve 28 remain closed.

[0029] To facilitate operation, the device further includes an alarm unit, which includes a prompter 51, which is electrically connected to the controller 41. Through the alarm unit, when the water pump and the solenoid valve 28 malfunction, or when the values ​​detected by the first water level sensor 31 and the first EC sensor 32 exceed a preset range, the prompter 51 prompts manual intervention.

[0030] For ease of operation, the control unit also includes a wireless communication unit 42 and a host computer 43 electrically connected to the controller 41. The host computer 43 is connected to the controller 41 through the wireless communication unit 42. The host computer 43 can be a computer or a smart phone. After the data is collected by the detection unit, it can be manually controlled by the host computer 43 or controlled by a preset program.

[0031] For ease of operation, the liquid supply unit also includes a fertilizer adding bucket 221 and an agitator 222 mounted on the nutrient solution tank 22. A fertilizer adding valve 223 is located at the outlet of the fertilizer adding bucket 221. Fertilizer addition is controlled by opening and closing the fertilizer adding valve 223. The detection unit also includes a second water level sensor 33 and a second EC sensor 34 located within the nutrient solution tank 22. A controller 41 is electrically connected to the second water level sensor 33, the second EC sensor 34, the fertilizer adding valve 223, and the agitator 222. The agitator 222 is a conventional stirring mechanism. The second water level sensor 33 and the second EC sensor 34 detect the water level and fertilizer concentration of the nutrient solution in the nutrient solution tank 22. Fertilizer is added to the nutrient solution tank 22 via the fertilizer adding bucket 221 and the fertilizer adding valve 223. Multiple fertilizer adding buckets 221 may be provided to accommodate different fertilizers as needed. The agitator 222 uniformly stirs the fertilizer water in the nutrient solution tank 22. It should be noted that the fertilizer concentration in the nutrient solution pool 22 should be at least the same as that required by the seedling pool 12 , or slightly higher than that required by the seedling pool 12 .

[0032] For the convenience of operation, a water supply pipe 29 is provided between the water source pool 21 and the nutrient solution pool 22. The position of the water source pool 21 is higher than that of the nutrient solution pool 22, and a solenoid valve 28 is provided on the water supply pipe 29. The solenoid valve 28 is electrically connected to the controller 41, so that the water source required for fertilizer water can be added to the nutrient solution pool 22 through the water source pool 21.

[0033] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
