[0022] Please refer to Figure 2Further, the first mixing component 30 includes a mixing component 31, a first water pump 32, a second water pump 33, a first water valve 34 and a second water valve 35. The liquid inlet end of the first water pump 32 is connected to the water tank 20, and the liquid outlet end is connected to one end of the mixing component 31 to transport the water in the water tank 20 to the mixing component 31. The liquid inlet end of the second water pump 33 is connected to the other end of the mixing component 31, and the liquid outlet end is connected to the first inlet to transport the universal fertilizer mixed water in the mixing component 31 to the mainstream pipe 51. The first water valve 34 is arranged on the pipeline between the first water pump 32 and the mixing component 31 to control the amount of water sent into the mixing component 31 and the flow rate of the water. The second water valve 35 is arranged on the pipeline between the second water pump 33 and the first inlet, so that when the universal fertilizer mixed water is mixed, the second water valve 35 is closed, and the second water valve 35 is opened after the universal fertilizer mixed water is mixed, so as to send the universal fertilizer mixed water into the mainstream pipe 51.

[0023] Please refer to Figure 3 Furthermore, the mixing component 31 includes a mixing box 311, a spraying main pipe 313 and at least one spraying branch pipe 314 with the same structure. The two ends of the mixing box 311 are respectively connected to the liquid outlet of the first water pump 32 and the liquid inlet of the second water pump 33. The top surface of the mixing box 311 is provided with an inlet 312 for adding fertilizers required by each solar greenhouse into the mixing box 311 to mix universal fertilizer mixed water in the mixing box 311.

[0024] In this embodiment, each shunt pipe 52 is equipped with a third water valve 53 to control the opening or closing of the shunt pipe 52, closing the shunt pipe 52 connected to the solar greenhouse that does not need irrigation, and opening the shunt pipe 52 connected to the solar greenhouse that needs irrigation, thereby realizing batch irrigation of the solar greenhouse.

[0025] Please refer to Figure 4Furthermore, the fertilizer adding component 41 includes a fertilizer box 411, an extraction pump 412, a first fertilizer adding pipe 413, a second fertilizer adding pipe 414 and a fourth water valve 415. The input end of the first fertilizer adding pipe 413 is connected to the discharge pipe 42, and the output end is connected to the liquid inlet end of the extraction pump 412. The extraction end of the extraction pump 412 extends into the fertilizer box, and the liquid outlet end is connected to the input end of the second fertilizer adding pipe 414. The output end of the second fertilizer adding pipe 414 is connected to the discharge pipe 42, so that part of the universal fertilizer mixed water is extracted from the discharge pipe 42 by the extraction pump 412, and this part of the universal fertilizer mixed water is mixed with the corresponding solar greenhouse characteristic fertilizer extracted from the fertilizer box 411 by the extraction pump 412 and then sent to the second fertilizer adding pipe 413; at the same time, the remaining universal fertilizer mixed water is discharged along the discharge pipe 42. Continue to move, and the remaining universal fertilizer mixed water and part of the universal fertilizer mixed water after mixing with the special fertilizer are mixed at the connection between the second fertilizer adding pipe 414 and the discharge pipe 42, and are formulated into the special fertilizer mixed water required by the corresponding solar greenhouse. After two mixings, the special fertilizer and the universal fertilizer mixed water are mixed more fully; and by sending part of the universal fertilizer mixed water into the first fertilizer adding pipe 413, the flow rate of the universal fertilizer mixed water in the discharge pipe 42 can be reduced, so that the special fertilizer and the universal fertilizer mixed water are mixed more fully, so that the components in the formulated special fertilizer mixed water are more uniform, and the effect of spraying on crops is better. The fourth water valve 415 is installed on the first fertilizer adding pipe 413 to close the fourth water valve 415 when there is no need to add special fertilizer in the corresponding solar greenhouse.

[0026] Furthermore, the fertilizer adding assembly further includes a fifth water valve 416, a sixth water valve 417, a first flow meter 418 and a second flow meter 419. The fifth water valve 416 is installed on the discharge pipe 42 and is located below the connection between the first fertilizer adding pipe 413 and the discharge pipe 42. The first flow meter 418 is installed on the discharge pipe 42 and is located between the fifth water valve 416 and the first fertilizer adding pipe 413 to monitor the water flow of the discharge pipe 42 through the first flow meter 418 and adjust the water flow of the discharge pipe 42 through the fifth water valve 416. The sixth water valve 417 is installed on the second fertilizer adding pipe 414. The second flow meter 418 is installed on the discharge pipe 42 and is located below the connection between the first fertilizer adding pipe 413 and the discharge pipe 42. 9 is installed on the second fertilizer adding pipe 414 and is located between the sixth water valve 417 and the output end of the second fertilizer adding pipe 414 to monitor the water flow of the second fertilizer adding pipe 414 through the second flow meter 419 and adjust the water flow of the second fertilizer adding pipe 414 through the sixth water valve 417. In this way, by adjusting the flow of the universal fertilizer mixed water in the discharge pipe 42 and the flow of the corresponding solar greenhouse characteristic fertilizer in the second fertilizer adding pipe 414, the universal fertilizer mixed water and the characteristic fertilizer can be mixed more fully when mixed at the connection between the second fertilizer adding pipe 414 and the discharge pipe 42, so that the components in the prepared special fertilizer mixed water are more uniform.

[0027] In this embodiment, the second mixing component 40 further includes a fertilizer mixer 43, which is disposed at the connection between the discharge pipe 42 and the fertilization equipment of the solar greenhouse. The fertilizer mixer 43 is equipped with rotatable blades to mix the fertilizer added from the fertilizer adding component 41 to the discharge pipe 42 with the universal fertilizer in the discharge pipe 42.

[0028] When passing through the fertilizer mixer, the fan blades rotate under the action of water pressure and fully stir the fertilizer and general fertilizer mixed water, making the components in the prepared special fertilizer mixed water more uniform.

[0029] In one embodiment, in order to prevent the fertilizer-mixed water from not being fully sprayed onto the crops in each solar greenhouse due to too low water pressure, the water pressure of the diversion assembly 50 can be increased by replacing the second water pump 33 with a higher power, thereby increasing the water pressure of the discharge pipe 42, so that the fertilizer-mixed water can be fully sprayed onto the crops in each solar greenhouse. This solution only requires replacing the second water pump 33. This method only requires replacing one water pump, and the cost is relatively low.

[0030] In one embodiment, in order to prevent the fertilizer-mixed water from not being fully sprayed onto the crops in each solar greenhouse due to low water pressure, a third water pump can be installed on each discharge pipe 42 to increase the water pressure of the discharge pipe 42 so that the fertilizer-mixed water can be fully sprayed onto the crops in the solar greenhouse. This solution can adjust the power of the third water pump according to the size of the solar greenhouse so that the water pressure in the discharge pipe 42 is matched with the spraying area of ​​the solar greenhouse, thereby avoiding the normal operation of the fertilization equipment being affected by excessive water pressure.

[0031] In one embodiment, the water supply and fertilizer distribution device 10 for a solar greenhouse can also be used to spray pesticides on crops in the solar greenhouse. First, the pesticides required by all crops in the solar greenhouse are added to the mixing box 311, and then according to the type of crops in each solar greenhouse, the pesticides required by each solar greenhouse are added to the fertilizer box 411 of the solar greenhouse. In this way, corresponding pesticides can be sprayed on different crops in multiple different solar greenhouses.

[0032] In Example 1, when irrigating multiple different crops planted in a single solar greenhouse at the same time, first set a corresponding number of second mixing components and fertilization equipment according to the number of crop types, and then connect each second mixing component to each fertilization equipment. In this way, each second mixing component can adjust the general fertilizer mixed water into a special fertilizer mixed water that meets the needs of one of the crops according to the type of crop, so as to achieve the corresponding fertilizer mixed water for irrigation of multiple different crops in a solar greenhouse at the same time.

[0033] Example 2, the steps for simultaneously irrigating multiple solar greenhouses planted with different crops are as follows:

[0034] 1. Choose the corresponding fertilizer according to the type of crops in the greenhouse to be irrigated;

[0035] 2. Add the fertilizers required by all crops in the solar greenhouse to the mixing box 311, and add the special fertilizers required by each solar greenhouse to the fertilizer box 411 of the solar greenhouse;

[0036] 3. Open the third water valve 53 of the shunt pipe 52 corresponding to the solar greenhouse that needs irrigation, and close the third water valve 53 of the shunt pipe 52 corresponding to the solar greenhouse that does not need irrigation;

[0037] 4. Open the first water valve 34, close the second water valve 35, and inject water into the mixing box 311. When the water volume in the mixing box 311 reaches a predetermined volume, close the first water valve 34;

[0038] 5. Open the second water valve 35 to allow the universal fertilizer mixed water to flow into the corresponding solar greenhouse discharge pipe 42 along the shunt pipe 52. The universal fertilizer mixed water in the discharge pipe 42 of each solar greenhouse is mixed with the fertilizer in the fertilizer box 411 of the solar greenhouse to prepare the special fertilizer mixed water for the solar greenhouse.

[0039] 6. The special fertilizer mixed water of each solar greenhouse enters the fertilization equipment of the solar greenhouse along the discharge pipe 42 of the solar greenhouse to fertilize the crops in the solar greenhouse.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
