Description

The present invention is in the technical field of integrated water and fertilizer irrigation for citrus, and particularly relates to a citrus-based integrated water and fertilizer irrigation method and system. Background Citrus need to be irrigated during drought months. Therefore, they must be irrigated during winter drought and when the temperature is above 13 degrees Celsius. The branches and leaves of citrus tend to allow water m fruits to flow to the leaves, causing the fruits to wilt. Current irrigation is mainly carried out by furrow irrigation or upper canopy sprinkler irrigation. When it is necessary to fertilize citrus during irrigation, fertilizers are usually mixed into water to enable fertilization while watering, thereby achieving integrated water and fertilizer irrigation. Due to the different growth situations and environments of citrus, it is necessary to continue adjusting water and fertilizer accordingly during the water and fertilizer irrigation to adapt to the different growth situations and environments. Therefore, it is necessary to provide a citrus-based integrated water and fertilizer irrigation method and system, which can adjust different water-to-fertilizer ratios under different growth situations and environments of citrus, so as to ensure the growth quality of citrus. Summary of the Invention 11 08 25 An object of the present invention is to provide an integrated water and fertilizer irrigation method and system in order to solve the above-mentioned problems in the background. To solve the above-mentioned technical problems, the present invention provides the subject matter defined in the Claims and reference is made thereto. Compared with the prior art, the advantageous effects achieved by the present invention are as follows. According to the present invention, by providing the second water pump and the third water pump for pumping the liquid and the fertilizer into the central barrel and then controlling the sprayer to swing up and down, the branches and roots of citrus can simultaneously be irrigated via the sprayer, so as to ensure the nutrients and moisture of the growing citrus, and different water-to-fertilizer ratios can be adjusted under different growth situations and environments of citrus, so as to ensure the growth quality of citrus. By providing the cylinders, the wiping plates, and the plug rod, the cleanliness of the humidity detector and the plug rod can be ensured, and data is ensured to be more accurate, so as to make the soil humidity data for the next test more accurate, and at the same time, by inserting the plug rod into the soil, the humidity inside the soil can be further detected. By providing the liquid level sensor, the remaining liquid fertilizer in the central barrel can be detected when switching the grade of the liquid fertilizer, so as to avoid the effect of the excessive remaining liquid fertilizer in the central barrel on the quality of switching liquid fertilizer concentration, and at the same time, the previous liquid fertilizer can be recycled, thereby saving costs.

With reference to Fig. 5, a citrus-based integrated water and fertilizer irrigation method and system, the system further comprising an integrated water and fertilizer irrigation system. The integrated water and fertilizer irrigation system comprises a signal receiving module and a control module, wherein the signal receivmg module comprises a humidity receivmg submodule electrically connected to the humidity detector 15, an image receiving submodule electrically connected to the camera 5, an identification submodule for analyzing irrigation situations, a concentration receiving submodule electrically connected to the concentration detector 3, and a liquid level receivmg submodule electrically connected to the liquid level sensor 23; the control module comprises a rotation submodule electrically connected to the 11 08 25 driven rotation device, a wiping submodule electrically connected to the cylinders 13, an adjusting submodule comprising a first startup unit electrically connected to the second water pump 24, a second startup unit electrically connected to the third water pump 25, and a third startup unit electrically connected to the bidirectional pump 27, and a driver submodule electrically connected to the motor 17. Example 1: The integrated water and fertilizer irrigation system included the following irrigation methods: Step 1, when irrigation was needed, the power vehicle was started, and the transport section 1 was pulled to move on a citrus field. When it was necessary to detect the humidity of soil, the power vehicle was stopped, so as to conveniently detect the soil moisture in the citrus field to determine the dry condition of the soil; Specifically, when the transport section 1 stopped at a location in the citrus field, the motor 17 was started by the driver submodule to drive the plug rod 11 to move downwards until it was inserted into the soil to stand for a period of time. The motor 17 was then reversed to drive the plug rod 11 to move upwards. When the plug rod 11 moved to the front of the humidity detector 15, the humidity on the surface of the plug rod 11 was detected by the humidity detector 15, and the obtained value was transmitted to the humidity receiving submodule where a normal humidity value was set as Range a. Comparing the real-time detected humidity value with the set-value a by the identification submodule, if the value was within the range of a, it indicated that the humidity of the soil was normal, and if the real-time detected humidity value was less than a, it indicated that the soil was relatively dry. It should be noted that when it was necessary to detect the soil moisture next 11 08 25 time, as the plug rod 11 moved downwards, the wiping unit was started to controll the cylinders 13 to extend, the wiping plates 14 were drove to contact the surface of the plug rod 11 to wipe off the soil on the surface of the plug rod 11, so as to ensure the surface cleanliness of the plug rod 11 and thus make the soil humidity data for the next test more accurate. Step 2, while the soil moisture in the citrus field was detected, the camera 5 started to capture the growth situation of citrus trees and transmit it to the image receiving submodule. Photos of mature and immature growth were set in the image receiving submodule to determine whether the citrus trees were mature; Step 3, the dry condition of the soil was combmed with the growth situation of the citrus trees. A water-to-fertilizer ratio was adjusted according to different conditions, and then the water and fertilizer integrated fertilizer was sprayed via the sprayer 4 to achieve high-quality irrigation; Specifically, the proportion grade of the liquid fertilizer was set as Grade A, Grade B, and Grade C in the concentration submodule, where Grade A represented a high fertilizer proportion, Grade B represented a medium fertilizer proportion, and Grade C represented a low fertilizer proportion. Step 3 included the following specific steps: Step 3-a, when the citrus trees were mature and the citrus field had low moisture content, a signal was transmitted to the adjusting submodule, and the proportion of the liquid fertilizer was controlled to be Grade C; Specifically, by opening the second water pump 24 via the first startup unit and the third water pump 25 via the second startup unit, the liquid and the fertilizer were 11 08 25 pumped into the central barrel 21. At this time, the concentration of the liquid fertilizer in the central barrel 21 was detected by the concentration detector 3, and the detected concentration was transmitted to the concentration receiving submodule in real-time. When the concentration value was detected to reach Grade C, the second water pump 24 and the third water pump 25 were closed, and the first water pump was opened to spray the liquid fertilizer out of the sprayer 4. Due to the low moisture content in the citrus field, the sprayer 4 was controlled by the rotation submodule to swing downwards, so that the nozzle of the sprayer 4 could be aligned with the roots of the citrus trees to supply water. By this step, excessive nutrition of citrus caused by excessive fertilizer for irrigation can be avoided; Step 3-b, when the citrus trees were mature and the citrus field had high moisture content, which indicated a good environment for the citrus field, without the need for irrigation they were allowed to grow naturally; Step 3-c, when the citrus trees were immature and the citrus field had high moisture content, a signal was transmitted to the adjusting submodule, and the proportion of the liquid fertilizer was controlled to be Grade A; Specifically, by opening the second water pump 24 via the first startup unit and the third water pump 25 via the second startup unit, the liquid and the fertilizer were pumped into the central barrel 21. At this time, the concentration of the liquid fertilizer in the central barrel 21 was detected by the concentration detector 3, and the detected concentration was transmitted to the concentration receiving submodule in real-time. When the concentration value was detected to reach Grade A, the second water pump 24 and the third water pump 25 were closed, and the first water pump 11 08 25 was opened to spray the liquid fertilizer out of the sprayer 4. Since the immature citrus indicated that the citrus lacked nutrients and did not lack moisture, the sprayer 4 was controlled by the rotation submodule to swing upwards, so that the nozzle of the sprayer 4 could be aligned with the branches of the citrus trees to supply nutrients, so as to ensure that citrus had sufficient nutrients during the growth process; Step 3-d, when the citrus trees were immature and the citrus field had low moisture content, a signal was transmitted to the adjusting submodule, and the proportion of the liquid fertilizer was controlled to be Grade B; Specifically, by opening the second water pump 24 via the first startup unit and the third water pump 25 via the second startup unit, the liquid and the fertilizer were pumped into the central barrel 21. At this time, the concentration of the liquid fertilizer in the central barrel 21 was detected by the concentration detector 3, and the detected concentration was transmitted to the concentration receiving submodule in real-time. When the concentration value was detected to reach Grade B, the second water pump 24 and the third water pump 25 were closed, and the first water pump was opened to spray the liquid fertilizer out of the sprayer 4. Since the citrus field had low moisture content and the citrus trees were immature, the sprayer 4 was controlled by the rotation submodule to swing up and down, so that the branches and roots of citrus could simultaneously be irrigated via the sprayer 4, so as to ensure the nutrients and moisture of the growing citrus. By the steps of this example, different water-to-fertilizer ratios can be adjusted under different growth situations and environments of citrus, so as to ensure the growth quality of citrus. 11 08 25 Example 2: Based on the steps of Example 1, in order to ensure that the concentration of the liquid fertilizer in the central barrel 21 was not affected when the proportion grades of the liquid fertilizer were switched to each other, the integrated water and fertilizer irrigation system further included the following specific steps: QI, when switching the grade of the liquid fertilizer, the liquid level of the remaining liquid fertilizer in the central barrel 21 was detected by the liquid level sensor 23, and a signal was transmitted to the liquid level receiving submodule; Q2, when the liquid level of the remaining liquid fertilizer was lower than half of the height of the central barrel 21, which indicated that the central barrel 21 had space for switching the grade of the liquid fertilizer, it was only necessary to repeat step 3 of Example 1, that is, to adjust the liquid fertilizer to reach a suitable grade for irrigation; Q3, when the liquid level of the remaining liquid fertilizer was more than half of the height of the central barrel 21, which indicated that there was more remaining liquid fertilizer in the central barrel 21 so that there was no space for other liquids to enter when switching the grade of the liquid fertilizer, a signal was transmitted to the third startup unit, and the bidirectional pump 27 was started to pump all the remaining liquid fertilizer in the central barrel 21 into the transition chamber 22. At this time, step 3 of Example 1 was repeated, that is, the liquid fertilizer was adjusted to reach a suitable grade for irrigation; and Q4, when there was too much liquid fertilizer in the transition chamber 22, a part of the liquid fertilizer in the transition chamber 22 was pumped into the central barrel 21 via the bidirectional pump 27 when it was necessary to switch the grade of 11 08 25 the liquid fertilizer, so that the height of the entered liquid fertilizer was not more than half of the height of the central barrel 21. At this time, step 3 of Example 1 was repeated, that is, the grade of the liquid fertilizer in the central barrel (21) was adjusted to a suitable grade and then irrigation was performed. By this step, the previous liquid fertilizer can be recycled when switching the grade of the liquid fertilizer, thereby saving costs. By the steps of this example, the remaining liquid fertilizer in the central barrel 21 can be detected when switching the grade of the liquid fertilizer, so as to avoid the effect of the excessive remaining liquid fertilizer in the central barrel 21 on the quality of switching liquid fertilizer concentration, and at the same time, the previous liquid fertilizer can be recycled, thereby saving costs.
