Description of the main elements
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, fig. 1 is an application environment diagram of a preferred embodiment of the method for controlling fertilizer according to the present invention. The application environment diagram comprises electronic equipment 1, a fertilizer applicator 2 and a water supply pump 3, wherein the electronic equipment 1 is communicated with the fertilizer applicator 2, the electronic equipment 1 is also communicated with the water supply pump 3, and the fertilizer applicator 2 is connected with the water supply pump 3.
Wherein, the fertilizer applicator 2 comprises a fertilizer applicator flowmeter 21 and a liquid storage tank 22.
The fertilizer applicator flow meter 21 is used for inputting mother liquor into the liquid storage tank 22 and controlling the liquid outlet rate of the mother liquor;
the liquid storage tank 22 is used for receiving the mother liquid input by the fertilizer applicator flowmeter 21 and the clear water input by the water supply pump 3, and mixing the input mother liquid and the input clear water to obtain the fertilizer required by the crops.
Fig. 2 is a flow chart of a fertilizer control method according to a preferred embodiment of the present invention. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.
The fertilizer regulation and control method is applied to one or more electronic devices 1, wherein the electronic device 1 is a device capable of automatically performing numerical calculation and/or information processing according to a preset or stored instruction, and hardware of the electronic device includes but is not limited to a microprocessor, an Application Specific Integrated Circuit (ASIC), a Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), an embedded device, and the like.
The electronic device 1 may be any electronic product capable of performing human-computer interaction with a user, for example, a Personal computer, a tablet computer, a smart phone, a Personal Digital Assistant (PDA), a game machine, an interactive web Television (IPTV), an intelligent wearable device, and the like.
The electronic device 1 may also comprise a network device and/or a user device. The network device includes, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a Cloud Computing (Cloud Computing) based Cloud consisting of a large number of hosts or network servers.
The Network where the electronic device 1 is located includes, but is not limited to, the internet, a wide area Network, a metropolitan area Network, a local area Network, a Virtual Private Network (VPN), and the like.
S10, The electronic device 1 obtains The EC value of The current fertilizer concentration of The current crop (The value of EC).
In at least one embodiment of the invention, the EC value is used to measure soluble salt concentration in solution, and may also be used to measure soluble ion concentration in liquid fertilizer for a crop or in a growing medium for a crop.
It can be understood that the proportion relationship between the nutrient elements is different according to the different growth requirements of different crops on the nutrient elements, so that different nutrient solution formulas can be provided for different crops so as to provide nutrient substances meeting the requirements of the crops. That is, the EC-values of the fertilizers of different crops are different, and therefore, the electronic device 1 acquires a target EC-value for the current fertilizer of the current crop for subsequent comparison.
S11, the electronic device 1 detects the current EC value of the current fertilizer.
In at least one embodiment of the present invention, the current fertilizer is stored in the tank 22, and the tank 22 may contain an EC sensor for measuring the EC value of the fertilizer stored in the tank 22.
Specifically, the electronic device 1 detecting the current EC value of the current fertilizer includes:
the electronic device 1 obtains the measurement result of the EC sensor on the EC value of the current fertilizer in the liquid storage tank 22, and determines the measurement result as the current EC value of the current fertilizer.
Of course, in other embodiments, the electronic device 1 may also detect the current EC value of the current fertilizer in other manners, as long as the purpose of detecting the current EC value can be achieved, and the invention is not limited thereto.
And S12, when the current EC value is not consistent with the target EC value, the electronic device 1 acquires the current liquid outlet rate of the fertilizer applicator flow meter 21.
In at least one embodiment of the present invention, the electronic device 1 compares the current EC value with the target EC value to obtain a comparison result, and determines whether the current EC value is consistent with the target EC value according to the comparison result.
Further, when the current EC value is consistent with the target EC value, the electronic device 1 may directly irrigate the current crop with fertilizer in the liquid storage tank 22.
Further, when the current EC value is not consistent with the target EC value, the electronic device 1 obtains the current liquid output rate of the fertilizer applicator flow meter 21.
Specifically, the present invention does not limit the manner in which the electronic device 1 obtains the current liquid output rate of the fertilizer applicator flow meter 21.
For example: the fertilizer applicator flow meter 21 can record the liquid outlet rate and feed back the liquid outlet rate to the electronic device 1 in real time, and the electronic device 1 receives the liquid outlet rate fed back by the fertilizer applicator flow meter 21 in real time and determines the received current liquid outlet rate as the current liquid outlet rate of the fertilizer applicator flow meter 21 and the like.
S13, the electronic device 1 calculates the target liquid output rate of the fertilizer applicator flow meter 21.
In at least one embodiment of the invention, the product of the effluent rate of the fertilizer applicator flow meter 21 and the concentration of the mother liquor of the current fertilizer is equal to the product of the EC value of the current fertilizer and the water lift rate of the feed water pump 3.
In at least one embodiment of the present invention, the mother liquor of the current fertilizer refers to a concentrated liquor of the current fertilizer.
Specifically, the electronic device 1 obtains the demand of the current crop for the current fertilizer, and the electronic device 1 dissolves the current fertilizer, which is consistent with the demand, in water to obtain the mother liquor of the current fertilizer.
For example: the electronic device 1 dissolves the current fertilizer in accordance with the required amount into 100000L of water, resulting in a solution of the current fertilizer having an EC value of about 1.0 ms/cm. Further, when the EC value required for irrigation is 3.0ms/cm, if the fertilizer with the EC value of 3.0ms/cm is to be prepared, 100000/3L of water is required, the water volume is too large, and if a 100000/3L reservoir is to be built, great manpower and material resources are consumed, so that, for convenience of use, the electronic device 1 can prepare the current fertilizer into 200 times of concentrated solution, that is, 500L of high-concentration solution, that is, mother solution of the current fertilizer.
In at least one embodiment of the present invention, the electronic device 1 calculating the target effluent rate of the fertilizer applicator flow meter 21 comprises:
the electronic device 1 obtains the configured water lifting rate of the water supply pump 3 and the initial concentration of the mother liquor of the current fertilizer, and the electronic device 1 determines the target liquid outlet rate of the fertilizer applicator flow meter 21 according to the target EC value, the configured water lifting rate of the water supply pump 3 and the initial concentration of the mother liquor of the current fertilizer.
Specifically, since the product of the effluent rate of the fertilizer applicator flow meter 21 and the concentration of the mother liquor of the current fertilizer is equal to the product of the EC value of the current fertilizer and the water pumping rate of the water supply pump 3, after the configuration water pumping rate of the water supply pump 3 and the initial concentration of the mother liquor of the current fertilizer are obtained by the electronic device 1, the electronic device 1 can obtain the target effluent rate of the fertilizer applicator flow meter 21 by combining the target EC value of the current fertilizer of the current crop.
For example: when the configured water lifting rate of the water supply pump 3 is 233L/min and the initial concentration of the mother liquor of the current fertilizer is 200ms/cm, the target EC value is 2ms/cm, so the target liquid outlet rate of the fertilizer applicator flow meter 21 is 2.33L/min.
S14, the electronic device 1 adjusts the effluent rate of the fertilizer applicator flow meter 21 from the current effluent rate to the target effluent rate.
In at least one embodiment of the present invention, after the electronic device 1 calculates the target liquid output rate of the fertilizer applicator flow meter 21, the electronic device 1 adjusts the liquid output rate of the fertilizer applicator flow meter from the current liquid output rate to the target liquid output rate to meet the current crop demand for the EC value of the current fertilizer.
Specifically, the electronic device 1 may adjust the liquid output rate by controlling a liquid output valve of the fertilizer applicator 2, so as to adjust the current liquid output rate to the target liquid output rate. Alternatively, the electronic device 1 may input the target liquid output rate in the liquid output rate input box of the fertilizer applicator 2, so as to adjust the current liquid output rate to the target liquid output rate, and the like.
Of course, the electronic device 1 may also adjust the EC value of the current fertilizer of the current crop in other ways, and the specific technical solution will be described in detail below.
In at least one embodiment of the present invention, the effluent rate of the fertilizer applicator flow meter 21 is less than or equal to a maximum effluent rate, and when the target effluent rate is greater than the maximum effluent rate, the method further comprises:
the electronic device 1 obtains the maximum liquid outlet rate and the initial concentration of the mother liquor of the current fertilizer, determines a target water lifting rate of the water supply pump 3 according to the target EC value, the maximum liquid outlet rate and the initial concentration of the mother liquor of the current fertilizer, obtains the current water lifting rate of the water supply pump 3 by the electronic device 1, and adjusts the water lifting rate of the water supply pump 3 from the current water lifting rate to the target water lifting rate.
Specifically, since the product of the liquid outlet rate of the fertilizer applicator flow meter 21 and the concentration of the current fertilizer mother liquor is equal to the product of the EC value of the current fertilizer and the water lifting rate of the feed water pump 3, after the electronic device 1 obtains the maximum liquid outlet rate and the initial concentration of the current fertilizer mother liquor, the electronic device 1 can determine the target water lifting rate of the feed water pump 3 by combining the target EC value of the current fertilizer of the current crop.
For example: when the initial concentration of the mother liquor of the current fertilizer is a 200-time concentrated solution, if a solution of the current fertilizer with an EC value of 2.0ms/cm is to be obtained, the water extraction rate of the water supply pump 3 is calculated as the configured water extraction rate 233L/min, the liquid output rate of the fertilizer application flowmeter 21 should be 2.33L/min, the maximum liquid output rate of the fertilizer application flowmeter 21 is 2L/min, and since 2L/min is less than 2.33L/min, the electronic device 1 cannot adjust the EC value of the current fertilizer by adjusting the liquid output rate of the fertilizer application flowmeter 21 under the above conditions. Therefore, the electronic device 1 can adjust the EC value of the current fertilizer by the water lifting rate of the feed water pump 3 at this time.
Specifically, when the maximum liquid outlet rate is 2L/min and the initial concentration of the mother liquor of the current fertilizer is 200ms/cm, the target water lifting rate of the feed water pump 3 is 200L/min because the target EC value is 2 ms/cm. And the electronic equipment 1 adjusts the water lifting rate of the water supply pump 3 from the current water lifting rate to the target water lifting rate of 200L/min.
Specifically, the electronic device 1 may control the water outlet pipe of the water supply pump 3 to reduce the water yield so as to reduce the water lifting rate of the water supply pump 3 to 200L/min, or the electronic device 1 may input the target water lifting rate of 200L/min in the water lifting rate input frame of the water supply pump 3 so as to reduce the water lifting rate of the water supply pump 3 to 200L/min, and the like.
It should be noted that, the above manner is simple and easy to operate, and is suitable for use when the target liquid outlet rate is greater than the maximum liquid outlet rate.
In at least one embodiment of the invention, the water lift rate of the feed water pump 3 corresponds to the current fertilizer demand for irrigation of the current crop.
In at least one embodiment of the present invention, when the target water lift rate is less than the current fertilizer demand for irrigation of the current crop, the method further comprises:
the electronic device 1 obtains the configured water lifting rate and the maximum liquid outlet rate of the water supply pump 3, determines the target concentration of the mother liquor of the current fertilizer according to the target EC value and the configured water lifting rate and the maximum liquid outlet rate of the water supply pump 3, and the electronic device 1 obtains the initial concentration of the mother liquor of the current fertilizer and adjusts the concentration of the mother liquor of the current fertilizer from the initial concentration to the target concentration.
Specifically, since the product of the effluent rate of the fertilizer applicator flow meter 21 and the concentration of the current fertilizer mother liquor is equal to the product of the EC value of the current fertilizer and the water pumping rate of the water supply pump 3, after the configured water pumping rate of the water supply pump 3 and the maximum effluent rate are obtained by the electronic device 1, the electronic device 1 can determine the target concentration of the current fertilizer mother liquor by combining the target EC value of the current fertilizer of the current crop.
For example: in the above example, the calculated target water lifting rate is 200L/min, and in order to meet the demand of the current fertilizer for irrigation of the current crop, the configured water lifting rate of the water supply pump 3 is 400L/min, and since 200L/min <400L/min, the electronic device 1 cannot adjust the EC value of the current fertilizer in the above manner. At this time, the electronic device 1 may adjust the EC value of the current fertilizer by the concentration of the mother liquor of the current fertilizer.
Specifically, if the current fertilizer solution with the EC value of 2.0ms/cm is to be obtained, the maximum liquid outlet rate of the fertilizer applicator flow meter 21 is 2L/min, and the target concentration of the current fertilizer mother solution is increased by 400 times.
It should be noted that, due to the different solubility of the current fertilizer in water, the concentration of the mother liquor of the current fertilizer may be too high, which may result in insufficient dissolution of part of the chemical substances of the current fertilizer, and further result in imbalance of the nutrition proportion in the current fertilizer, and the above embodiment is no longer applicable.
That is, the concentration of the mother liquor of the current fertilizer is less than or equal to a maximum concentration, and when the target concentration is greater than the maximum concentration, the method further comprises:
the electronic equipment 1 increases the number of fertilizer applicators.

Fig. 3 is a functional block diagram of a fertilizer control device according to a preferred embodiment of the present invention. The fertilizer regulation and control device 11 comprises an acquisition unit 110, a detection unit 111, a calculation unit 112, an adjustment unit 113, a determination unit 114 and an addition unit 115. The module/unit referred to in the present invention refers to a series of computer program segments that can be executed by the processor 13 and that can perform a fixed function, and that are stored in the memory 12. In the present embodiment, the functions of the modules/units will be described in detail in the following embodiments.
The obtaining unit 110 obtains a target soluble salt concentration EC value (The value of EC) of a current fertilizer of a current crop.
In at least one embodiment of the invention, the EC value is used to measure soluble salt concentration in solution, and may also be used to measure soluble ion concentration in liquid fertilizer for a crop or in a growing medium for a crop.
It can be understood that the proportion relationship between the nutrient elements is different according to the different growth requirements of different crops on the nutrient elements, so that different nutrient solution formulas can be provided for different crops so as to provide nutrient substances meeting the requirements of the crops. That is, the EC values of the fertilizers of different crops are different, and thus, the obtaining unit 110 obtains a target EC value for the current fertilizer of the current crop for subsequent comparison.
The detection unit 111 detects the current EC value of the current fertilizer.
In at least one embodiment of the present invention, the current fertilizer is stored in the tank 22, and the tank 22 may contain an EC sensor for measuring the EC value of the fertilizer stored in the tank 22.
Specifically, the detecting unit 111 detecting the current EC value of the current fertilizer includes:
the detection unit 111 acquires the measurement result of the EC sensor on the EC value of the current fertilizer in the liquid storage tank 22, and determines the measurement result as the current EC value of the current fertilizer.
Of course, in other embodiments, the detecting unit 111 may also detect the current EC value of the current fertilizer in other manners, as long as the purpose of detecting the current EC value can be achieved, and the invention is not limited thereto.
When the current EC value is not consistent with the target EC value, the obtaining unit 110 obtains the current effluent rate of the fertilizer applicator flow meter 21.
In at least one embodiment of the present invention, the electronic device 1 compares the current EC value with the target EC value to obtain a comparison result, and determines whether the current EC value is consistent with the target EC value according to the comparison result.
Further, when the current EC value is consistent with the target EC value, the electronic device 1 may directly irrigate the current crop with fertilizer in the liquid storage tank 22.
Further, when the current EC value is not consistent with the target EC value, the obtaining unit 110 obtains the current effluent rate of the fertilizer applicator flow meter 21.
Specifically, the present invention does not limit the manner in which the obtaining unit 110 obtains the current liquid output rate of the fertilizer applicator flow meter 21.
For example: the fertilizer applicator flow meter 21 may record a liquid outlet rate, and feed back the liquid outlet rate to the obtaining unit 110 in real time, and the obtaining unit 110 receives the liquid outlet rate fed back by the fertilizer applicator flow meter 21 in real time, and determines the received current liquid outlet rate as the current liquid outlet rate of the fertilizer applicator flow meter 21, and the like.
The calculation unit 112 calculates the target effluent rate of the fertilizer applicator flow meter 21.
In at least one embodiment of the invention, the product of the effluent rate of the fertilizer applicator flow meter 21 and the concentration of the mother liquor of the current fertilizer is equal to the product of the EC value of the current fertilizer and the water lift rate of the feed water pump 3.
In at least one embodiment of the present invention, the mother liquor of the current fertilizer refers to a concentrated liquor of the current fertilizer.
Specifically, the obtaining unit 110 obtains the amount of the current fertilizer required by the current crop, and the electronic device 1 dissolves the current fertilizer in water, which is consistent with the required amount, to obtain the mother liquor of the current fertilizer.
For example: the electronic device 1 dissolves the current fertilizer in accordance with the required amount into 100000L of water, resulting in a solution of the current fertilizer having an EC value of about 1.0 ms/cm. Further, when the EC value required for irrigation is 3.0ms/cm, if the fertilizer with the EC value of 3.0ms/cm is to be prepared, 100000/3L of water is required, the water volume is too large, and if a 100000/3L reservoir is to be built, great manpower and material resources are consumed, so that, for convenience of use, the electronic device 1 can prepare the current fertilizer into 200 times of concentrated solution, that is, 500L of high-concentration solution, that is, mother solution of the current fertilizer.
In at least one embodiment of the present invention, the calculating unit 112 calculating the target effluent rate of the fertilizer applicator flow meter 21 comprises:
the calculating unit 112 obtains the configured water lifting rate of the water supply pump 3 and the initial concentration of the mother liquor of the current fertilizer, and the calculating unit 112 determines the target liquid outlet rate of the fertilizer applicator flow meter 21 according to the target EC value, the configured water lifting rate of the water supply pump 3 and the initial concentration of the mother liquor of the current fertilizer.
Specifically, since the product of the effluent rate of the fertilizer applicator flow meter 21 and the concentration of the mother liquor of the current fertilizer is equal to the product of the EC value of the current fertilizer and the water pumping rate of the water supply pump 3, after the calculation unit 112 obtains the configured water pumping rate of the water supply pump 3 and the initial concentration of the mother liquor of the current fertilizer, the calculation unit 112 combines the target EC value of the current fertilizer of the current crop to obtain the target effluent rate of the fertilizer applicator flow meter 21.
For example: when the configured water lifting rate of the water supply pump 3 is 233L/min and the initial concentration of the mother liquor of the current fertilizer is 200ms/cm, the target EC value is 2ms/cm, so the target liquid outlet rate of the fertilizer applicator flow meter 21 is 2.33L/min.
The adjusting unit 113 adjusts the effluent rate of the fertilizer applicator flow meter 21 from the current effluent rate to the target effluent rate.
In at least one embodiment of the present invention, after the calculating unit 112 calculates the target liquid output rate of the fertilizer applicator flow meter 21, the adjusting unit 113 adjusts the liquid output rate of the fertilizer applicator flow meter from the current liquid output rate to the target liquid output rate to meet the current crop demand for the current fertilizer EC value.
Specifically, the adjusting unit 113 may adjust the liquid output rate by controlling a liquid output valve of the fertilizer applicator 2, so as to adjust the current liquid output rate to the target liquid output rate. Alternatively, the adjusting unit 113 may input the target liquid output rate in a liquid output rate input box of the fertilizer applicator 2, so as to adjust the current liquid output rate to the target liquid output rate, and the like.
Of course, the adjusting unit 113 may also adjust the EC value of the current fertilizer of the current crop in other ways, and the specific technical solution will be described in detail below.
In at least one embodiment of the present invention, the effluent rate of the fertilizer applicator flow meter 21 is less than or equal to a maximum effluent rate, and when the target effluent rate is greater than the maximum effluent rate, the method further comprises:
the obtaining unit 110 obtains the maximum liquid outlet rate and the initial concentration of the mother liquor of the current fertilizer, the determining unit 114 determines a target water lifting rate of the feed water pump 3 according to the target EC value, the maximum liquid outlet rate and the initial concentration of the mother liquor of the current fertilizer, the obtaining unit 110 obtains a current water lifting rate of the feed water pump 3, and the adjusting unit 113 adjusts the water lifting rate of the feed water pump 3 from the current water lifting rate to the target water lifting rate.
Specifically, since the product of the liquid outlet rate of the fertilizer applicator flow meter 21 and the concentration of the mother liquor of the current fertilizer is equal to the product of the EC value of the current fertilizer and the water lifting rate of the feed water pump 3, after the obtaining unit 110 obtains the maximum liquid outlet rate and the initial concentration of the mother liquor of the current fertilizer, the determining unit 114 can determine the target water lifting rate of the feed water pump 3 by combining the target EC value of the current fertilizer of the current crop.
For example: when the initial concentration of the mother liquor of the current fertilizer is a 200-time concentrated solution, if a solution of the current fertilizer with an EC value of 2.0ms/cm is to be obtained, and the water extraction rate of the water supply pump 3 is calculated as the configured water extraction rate 233L/min, the liquid output rate of the fertilizer applicator flow meter 21 should be 2.33L/min, and the maximum liquid output rate of the fertilizer applicator flow meter 21 is 2L/min, because 2L/min is less than 2.33L/min, the adjusting unit 113 cannot adjust the EC value of the current fertilizer by adjusting the liquid output rate of the fertilizer applicator flow meter 21 under the above-mentioned conditions. Therefore, the adjusting unit 113 can adjust the EC value of the current fertilizer by the water lifting rate of the feed water pump 3 at this time.
Specifically, when the maximum liquid outlet rate is 2L/min and the initial concentration of the mother liquor of the current fertilizer is 200ms/cm, the target water lifting rate of the feed water pump 3 is 200L/min because the target EC value is 2 ms/cm. The adjusting unit 113 adjusts the water lifting rate of the feed water pump 3 from the current water lifting rate to the target water lifting rate of 200L/min.
Specifically, the adjusting unit 113 may control the outlet pipe of the water supply pump 3 to decrease the water yield so as to decrease the water lifting rate of the water supply pump 3 to 200L/min, or the adjusting unit 113 may input the target water lifting rate of 200L/min in the water lifting rate input frame of the water supply pump 3 so as to decrease the water lifting rate of the water supply pump 3 to 200L/min, and the like.
It should be noted that, the above manner is simple and easy to operate, and is suitable for use when the target liquid outlet rate is greater than the maximum liquid outlet rate.
In at least one embodiment of the invention, the water lift rate of the feed water pump 3 corresponds to the current fertilizer demand for irrigation of the current crop.
In at least one embodiment of the present invention, when the target water lift rate is less than the current fertilizer demand for irrigation of the current crop, the method further comprises:
the obtaining unit 110 obtains the configured water pumping rate and the maximum liquid outlet rate of the feed water pump 3, the determining unit 114 determines the target concentration of the mother liquor of the current fertilizer according to the target EC value and the configured water pumping rate and the maximum liquid outlet rate of the feed water pump 3, the obtaining unit 110 obtains the initial concentration of the mother liquor of the current fertilizer, and the adjusting unit 113 adjusts the concentration of the mother liquor of the current fertilizer from the initial concentration to the target concentration.
Specifically, since the product of the effluent rate of the fertilizer applicator flow meter 21 and the concentration of the current fertilizer mother liquor is equal to the product of the EC value of the current fertilizer and the water pumping rate of the feed water pump 3, after the configuration water pumping rate of the feed water pump 3 and the maximum effluent rate are obtained by the obtaining unit 110, the determining unit 114 can determine the target concentration of the current fertilizer mother liquor by combining the target EC value of the current fertilizer of the current crop.
For example: in the above example, the calculated target water lifting rate is 200L/min, and in order to meet the demand of the current fertilizer for irrigation of the current crop, the configured water lifting rate of the feed water pump 3 is 400L/min, and since 200L/min <400L/min, the adjusting unit 113 cannot adjust the EC value of the current fertilizer in the above manner. At this time, the adjusting unit 113 may adjust the EC value of the current fertilizer by the concentration of the mother liquor of the current fertilizer.
Specifically, if the current fertilizer solution with the EC value of 2.0ms/cm is to be obtained, the maximum liquid outlet rate of the fertilizer applicator flow meter 21 is 2L/min, and the target concentration of the current fertilizer mother solution is increased by 400 times.
It should be noted that, due to the different solubility of the current fertilizer in water, the concentration of the mother liquor of the current fertilizer may be too high, which may result in insufficient dissolution of part of the chemical substances of the current fertilizer, and further result in imbalance of the nutrition proportion in the current fertilizer, and the above embodiment is no longer applicable.
That is, the concentration of the mother liquor of the current fertilizer is less than or equal to a maximum concentration, and when the target concentration is greater than the maximum concentration, the method further comprises:
the addition unit 115 increases the number of fertilizer applicators.
In this way, the increasing unit 115 can adjust the EC value of the current fertilizer by increasing the number of fertilizer applicators in the case that none of the above embodiments is applicable.
In conclusion, the method can obtain the EC value of the target soluble salt concentration of the current fertilizer of the current crop; detecting a current EC value of the current fertilizer; when the current EC value is not consistent with the target EC value, acquiring the current liquid outlet rate of a flow meter of the fertilizer applicator; calculating the target liquid outlet rate of the fertilizer applicator flowmeter; adjusting the effluent rate of the fertilizer applicator flow meter from the current effluent rate to the target effluent rate. Therefore, the EC value of the fertilizer can be automatically adjusted to meet the requirement of crops on the fertilizer, the adjustment process is convenient, large errors caused by manual operation are avoided, the workload of a user is reduced, and better experience is brought to the user.
