[0034] A concentration detector 3 and a liquid level sensor 23 are fixed inside the central barrel 21 , which can detect the fertilizer concentration in the central barrel 21 and the transition chamber 22 respectively.

[0035] The central barrel 21 is provided with a transmission pipe 28 inside the transition chamber 22 , and the transmission pipe 28 is connected to a bidirectional pump 27 .

[0036] Please refer to Figure 5, a water-fertilizer integrated irrigation method and system for citrus, which also includes a water-fertilizer integrated irrigation system. The water-fertilizer integrated irrigation system includes a signal receiving module and a control module. The signal receiving module includes a humidity receiving submodule, an image receiving submodule, an identification submodule, a concentration receiving submodule, and a liquid level receiving submodule. The concentration receiving submodule is electrically connected to the concentration detector 3, the humidity receiving submodule is electrically connected to the humidity detector 15, the image receiving submodule is electrically connected to the camera 5, the identification submodule is used to analyze the irrigation situation, and the liquid level receiving submodule is electrically connected to the liquid level sensor 23.

[0037] The control module includes a rotating submodule, a wiping submodule, an adjusting submodule and a driving submodule. The rotating submodule is electrically connected to the driving rotating device, the wiping submodule is electrically connected to the cylinder 13, the driving submodule is electrically connected to the motor 17, and the adjusting submodule includes a starting unit 1, a starting unit 2 and a starting unit 3. The starting unit 1 is electrically connected to the second water pump 24, the starting unit 2 is electrically connected to the third water pump 25, and the starting unit 3 is electrically connected to the bidirectional pump 27.

[0038] Example 1: The water-fertilizer integrated irrigation system includes the following irrigation methods:

[0039] Step 1: When irrigation is needed, start the power vehicle and pull the transport unit 1 to move in the citrus field. When soil moisture needs to be checked, stop the power vehicle to facilitate the detection of soil moisture in the citrus field to determine the dryness of the soil.

[0040] Specifically, when the transport unit 1 moves to a place in the citrus field and stops, the motor 17 is started by the driving submodule, so that the motor 17 drives the insertion rod 11 to move downward until it is inserted into the soil and rests for a period of time. Then, the motor 17 is reversed to drive the insertion rod 11 to move upward. When the insertion rod 11 moves in front of the humidity detector 15, the humidity detector 15 detects the humidity on the surface of the insertion rod 11 and transmits the value to the humidity receiving submodule. The normal humidity value is set in the humidity receiving submodule to a range a. The real-time detected humidity value is compared with the set value a through the comparison of the recognition submodule. If it is within the range a, it indicates that the soil humidity is normal. If the real-time detected humidity value is less than a, it indicates that the soil is relatively dry.

[0041] It should be noted that when the soil moisture needs to be tested next time, the wiping unit is started when the rod 11 moves downward, and the cylinder 13 is controlled to extend, driving the wiping plate 14 to contact the surface of the rod 11, and the dirt on the surface of the rod 11 is wiped off to ensure the cleanliness of the surface of the rod 11, so that the soil moisture data of the next test is more accurate.

[0042] Step 2: While detecting the moisture content of the soil in the citrus field, start the camera 5 to capture the growth of the citrus trees and transmit the captured images to the image receiving submodule. The image receiving submodule sets the images of mature and immature citrus trees to determine whether the citrus trees are mature.

[0043] Step 3: Combine the dryness of the soil with the growth of the citrus trees, adjust the water-fertilizer ratio according to different conditions, and then spray the water-fertilizer fertilizer through the nozzle 4 to achieve high-quality irrigation;

[0044] Specifically, in the concentration submodule, the proportion levels of the fertilizing solution are set as A, B, and C, where A is a high fertilizer proportion, B is a medium fertilizer proportion, and C is a low fertilizer proportion.

[0045] Step 3 includes the following specific steps:

[0046] Step 3-a: When the citrus trees are mature and the citrus fields have little water, the signal is transmitted to the adjustment submodule to control the proportion of the fertilizer solution to level C;

[0047] Specifically, the second water pump 24 is started by starting the first unit, and the third water pump 25 is started by starting the second unit to pump the liquid and fertilizer into the interior of the central barrel 21 respectively. At this time, the concentration of the fertilizing liquid in the central barrel 21 is detected by the concentration detector 3, and the detected concentration is transmitted to the concentration receiving submodule in real time. When the concentration value reaches level C, the second water pump 24 and the third water pump 25 are turned off, and the first water pump is started at this time to spray the fertilizing liquid from the nozzle 4. Since the citrus field has little moisture, the rotating submodule controls the nozzle 4 to swing downward so that the nozzle of the nozzle 4 can be aimed at the roots of the citrus trees to provide moisture to the roots of the citrus trees. This step avoids excessive irrigation of fertilizers leading to excessive nutrition of the citrus.

[0048] Step 3-b: When the citrus trees are mature and the citrus field has plenty of water, it means the citrus field environment is good and no irrigation is needed, allowing it to grow naturally;

[0049] Step 3-c: When the citrus trees are immature and the citrus fields have a lot of water, the signal is transmitted to the adjustment submodule to control the proportion of the fertilizer solution to level A;

[0050] Specifically, the second water pump 24 is started by starting the first unit, and the third water pump 25 is started by starting the second unit to pump the liquid and fertilizer into the interior of the central barrel 21 respectively. At this time, the concentration of the fertilizing liquid in the central barrel 21 is detected by the concentration detector 3, and the detected concentration is transmitted to the concentration receiving submodule in real time. When the concentration value reaches level A, the second water pump 24 and the third water pump 25 are turned off, and the first water pump is started at this time to spray the fertilizing liquid from the nozzle 4. Since the immature growth of citrus indicates that the citrus lacks nutrients but not water, the rotating submodule controls the nozzle 4 to swing upward so that the nozzle of the nozzle 4 can be aimed at the branches of the citrus tree, providing nutrients to the branches of the citrus tree, and ensuring that the citrus has sufficient nutrients during the growth process;

[0051] Step 3-d: When the citrus trees are immature and the citrus fields have little water, the signal is transmitted to the adjustment submodule to control the proportion of the fertilizer solution to level B;

[0052] Specifically, the second water pump 24 is started by starting the first unit, and the third water pump 25 is started by starting the second unit to pump the liquid and fertilizer into the interior of the central barrel 21 respectively. At this time, the concentration of the fertilizing liquid in the central barrel 21 is detected by the concentration detector 3, and the detected concentration is transmitted to the concentration receiving submodule in real time. When the concentration value reaches level B, the second water pump 24 and the third water pump 25 are turned off, and the first water pump is started at this time to spray the fertilizing liquid from the sprinkler 4. Since the citrus field has little moisture and the citrus trees are not mature, the rotation submodule controls the sprinkler 4 to swing back and forth upward and downward, so that the sprinkler 4 can irrigate the citrus branches and citrus roots at the same time to ensure nutrients and moisture for the growing citrus.

[0053] Through the steps of this embodiment, different water-fertilizer ratios can be adjusted for different citrus growth environments to ensure the growth quality of citrus.

[0054] Example 2: Based on the steps in Example 1, in order to ensure that the concentration of the fertilizer solution in the central barrel 21 is not affected when the proportion levels of the fertilizer solution are switched, the water-fertilizer integrated irrigation system further includes the following specific steps:

[0055] Q1: When the fertilizer liquid is switched to a different level, the liquid level sensor 23 detects the liquid level of the remaining fertilizer liquid in the central barrel 21 and transmits the signal to the liquid level receiving submodule;

[0056] Q2: When the level of the remaining fertilizer solution is lower than half of the height of the central barrel 21, it means that the central barrel 21 has space for switching the level of the fertilizer solution. At this time, you only need to repeat step 3 of Example 1 to adjust the fertilizer solution to the appropriate level for irrigation.

[0057] Q3: When the liquid level of the remaining fertilizer liquid is higher than half of the height of the central barrel 21, it means that there is a lot of fertilizer liquid remaining in the central barrel 21. There is no space for other liquid to enter when switching the fertilizer liquid level. At this time, a signal is transmitted to the starting unit 3 to start the two-way pump 27 to pump all the remaining fertilizer liquid in the central barrel 21 into the transition chamber 22. At this time, step 3 of embodiment 1 is repeated to adjust the fertilizer liquid to an appropriate level suitable for irrigation.

[0058] Q4: When there is too much fertilizer liquid in the transition chamber 22, when it is necessary to switch the fertilizer liquid level, the two-way pump 27 is used to pump part of the fertilizer liquid in the transition chamber 22 into the central barrel 21, so that the height of the fertilizer liquid entering is no higher than half the height of the central barrel 21. At this time, step 3 of embodiment 1 is repeated to adjust the fertilizer liquid level in the central barrel 21 to the appropriate level before irrigation is carried out. This step allows the previous fertilizer liquid to be reused when changing the fertilizer liquid level, which can save costs.

[0059] Through the steps of this embodiment, the remaining fertilizer liquid in the central barrel 21 can be detected when switching the level of the fertilizer liquid, so as to avoid the remaining fertilizer liquid in the central barrel 21 affecting the quality of switching the fertilizer liquid concentration. At the same time, the previous fertilizer liquid can be recycled to save costs.
