[0030] Embodiment 1

[0031] As Figures 1 to 7 shown, in this embodiment, a device for cultivating selenium-rich sprouts is provided, including a base 1, a filtrate tank 2, a planting tank 3, and a selenium-rich solution tank 4. The base 1 is detachably provided with a filtrate tank 2, a planting tank 3, and a selenium-rich solution tank 4 in sequence from bottom to top. The bottom of the planting tank 3 is provided with water seepage holes 8, and the inside is provided with a planting sieve plate 9 for placing bean seeds. The bottom of the selenium-rich solution tank 4 is provided with a valve, and the inside is provided with a selenium-rich solution. The selenium-rich solution is a leaching solution of (natural) selenium ore powder. The valve can control whether the selenium-rich solution drips into the planting tank 3. A control unit 6 is provided on the base 1.

[0032] As an alternative solution, in this embodiment, a heating plate 5 is provided on the base 1. The heating plate 5 is communicatively connected to the control unit 6. The heating temperature of the heating plate 5 is 15°C - 30°C, which can provide a suitable growth temperature for the sprouts. The filtrate tank 2 is inserted into the upper opening of the heating plate 5. A drain pipe 19 is provided on the side of the bottom of the filtrate tank 2, and a drain valve is provided on the drain pipe 19 to facilitate timely drainage of excess seepage water and ensure the water quality and air quality in the planting tank 3.

[0033] As an alternative solution, in this embodiment, the filtrate tank 2 is a box with an open upper part. The upper opening of the filtrate tank 2 is provided with a stepped insertion slot, and the insertion slot is at least 10 cm high, which can realize the pre-soaking operation of the bean seeds in the planting tank 3. The planting tank 3 is inserted into the insertion slot. A temperature and humidity sensor 20 is provided in the planting tank 3 to facilitate understanding the growth requirements of the bean seeds according to the temperature and humidity in the planting tank 3 and performing temperature increase or watering operations. The temperature and humidity sensor 20 is communicatively connected to the control unit 6. A temperature and humidity display port is preferably provided on the base 1. The whole device is a box nested with another box, which is convenient and reliable to assemble and easy to disassemble when harvesting the sprouts.

[0034] As an alternative solution, in this embodiment, the planting tank 3 is a box with an open upper part. The bottom plate of the planting tank 3 is evenly distributed with water seepage holes 8, and at least one ventilation hole 7 is provided on the side plate. In this embodiment, a number of ventilation holes 7 are evenly distributed to provide oxygen required for the growth of the bean seeds. The diameter of the water seepage holes 8 is not greater than the minimum diameter of the bean seeds.

[0035] As an alternative, in this embodiment, the diameter of the water seepage holes 8 is 2 mm - 5 mm, which can ensure water seepage while avoiding too fast seepage flow. It is advisable to have a slow soaking process for the bean seeds. The distance between adjacent water seepage holes 8 is 4 mm - 10 mm; a light-shielding film or a light-shielding plate is pasted on the planting bin 3 to facilitate the growth of bean seedlings; the entire device can also be covered with a light-shielding cover. A light-shielding film or a light-shielding plate is pasted on the planting bin 3. By disassembling and installing the light-shielding film or the light-shielding plate, the light requirements of the sprout seedlings at different stages can be met.

[0036] As an alternative, in this embodiment, at least two layers of planting sieve plates 9 are movably sleeved in the planting bin 3, and preferably three layers are provided. The planting amount at one time is large enough to meet the usage amount of a family. Drainage holes are evenly distributed on the planting sieve plates 9 and several planting areas are divided by convex strips, which is convenient for evenly laying bean seeds on the planting sieve plates 9. In the later stage, seedling roots will grow under the drainage holes. When eating, the lower seedling roots can be directly cut off and then eaten, and the taste is better. If growing pea seedlings, a single-layer planting sieve plate 9 can be selected, and there is enough solution in the filtrate bin 2 so that the roots of the pea seedlings can absorb water, which is convenient for the growth of sprout seedlings; if growing bean sprouts, at most three layers of planting sieve plates 9 can be selected at one time, and water can be intermittently distributed on the surface of the bean sprouts.

[0037] As an alternative, in this embodiment, a top cover is snap-connected to the top of the selenium-rich solution bin 4, and drip holes are evenly distributed on the bottom plate. The distance between the drip holes is smaller than the diameter of the bean seeds, which is convenient for realizing uniform water distribution. A filter screen 10, selenium ore powder 22 and solution are sequentially arranged in the selenium-rich solution bin 4 from bottom to top, and a valve is arranged at the bottom of the selenium-rich solution bin 4. In this embodiment, the filter screen 10 can prevent the selenium ore powder 22 from blocking the drip holes; natural selenium ore powder 22, preferably nano-level selenium ore powder or selenium-rich soil powder, is used. In this embodiment, based on the natural selenium-rich mineral powder matrix, the selenium-rich solution is prepared by quickly extracting the effective selenium in the matrix, providing an easily absorbable selenium form for the sprout vegetables, so as to cultivate selenium-rich sprout vegetables with higher nutritional value. Preferably, a pH probe 21 and a concentration detector are arranged in the selenium-rich solution bin 4 to facilitate the detection of the selenium-rich solution in the selenium-rich solution bin 4. Since selenium in the soil and ore powder is more likely to precipitate when the pH is greater than 7, according to the detection data of the pH probe in the solution, an appropriate amount of interfering agent, such as baking soda, quicklime, etc., can be added to accelerate the dissolution and leaching of selenium. The selection basis is that sodium bicarbonate medium has a high leaching rate for selenium and is a leaching agent for effective selenium in the soil.

[0038] As an alternative, in this embodiment, a stirring mechanism is provided on the top cover. The stirring mechanism includes a stirring paddle 12 and a motor 11. The rotating shaft of the motor 11 passes through the top cover and is connected to the stirring paddle 12. The stirring paddle 12 is located in the middle of the selenium ore powder 22, facilitating the full stirring of the selenium ore powder 22 to dissolve the selenium element components. The motor 11 is communicatively connected to the control unit 6, enabling intermittent stirring. It can be set that within 24 hours of the dissolution of the selenium ore powder 22, stirring is performed for 10 minutes every 1 hour. The rotation speed of the motor 11 should be such that the selenium ore powder 22 can generate a centrifugal motion.

[0039] In this embodiment, an ultrasonic vibration rod can also be provided on the top cover of the selenium-rich solution tank 4. The ultrasonic vibration rod is immersed in the selenium solution in the selenium-rich solution tank 4 and is communicatively connected to the control unit 6. The main structure of the ultrasonic vibration rod includes the following parts: an ultrasonic generator, which is responsible for generating high-frequency electrical signals; an ultrasonic vibration rod (or transducer), a device that converts electrical energy into ultrasonic mechanical energy, usually composed of piezoelectric ceramic wafers (PZT wafers), which will generate mechanical vibrations under the action of an electric field; a coupler that connects the ultrasonic vibration rod to the selenium solution to ensure that the energy is transmitted to the liquid and accelerate the dissolution of selenium.

[0040] As an alternative, in this embodiment, the valve is a plug plate 13. A slot 15 is provided at the bottom of the selenium-rich solution tank 4. The plug plate 13 is inserted into the slot 15, equivalent to a plug valve. A pull handle 14 is provided on one side of the plug plate 13 for easy pulling. A notch corresponding to the plug plate 13 is provided at the top of the planting tank 3 to facilitate the pulling of the plug plate 13. After the drip holes are exposed, direct watering of the bean seeds in the planting tank 3 can be carried out, which is uniform and convenient to operate. Drip holes are evenly distributed on the bottom plate of the selenium-rich solution tank 4. During the cultivation process of the sprout vegetables, a large amount of selenium-rich solution is required to soak the bean seeds in the initial stage. After the sprout vegetables germinate, the plug plate 13 can be pulled out regularly to open the drip holes, and the sprout vegetables can be sprayed with selenium-rich solution 2 - 3 times a day.

[0041] As an alternative, in this embodiment, a water addition mechanism is further provided on the base 1. The water addition mechanism includes a water tank 16, a pump body 17, and a water addition pipe 18. The water tank 16 is snap-connected to the base 1 and is located on one side of the filtrate tank 2. A pump body 17 is provided in the water tank 16. One end of the water addition pipe 18 is connected to the pump body 17 and the other end is inserted into the top of the selenium-rich solution tank 4. The pump body 17 is communicatively connected to the control unit 6. The control unit 6 can control the water addition time of the pump body 17, generally for 1 minute at a time, to supplement the aqueous solution in the selenium-rich solution tank 4. Of course, if the water addition mechanism is not provided, the top cover of the selenium-rich solution tank 4 can also be directly opened to add water directly.

[0042] In the present invention, specific examples are used to illustrate the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation on the present invention.
