[0053] like Figure 5 ,Example 1,The present invention integrates precise irrigation decisions based on light, timing and soil moisture, and two precise fertilization decisions based on ratio and EC value.

[0054] Among them, (a) precise irrigation decision based on light

[0055] Irrigation decisions based on light are mainly divided into two modes: crop parameter model control and machine learning parameter control. The crop parameter model control automatically calculates the duration of a single irrigation according to the following formula;

[0056] I=A*Wm*J Formula (1)

[0057] I: single irrigation quota, unit, mL / m2; A: irrigation coefficient; Wm: accumulated light radiation value, unit, J / cm2; J: water volume multiple;

[0058] T=60*I*10-3 / (De*q) Formula (2)

[0059] T: single irrigation duration, unit, min; I: single irrigation quota, unit, mL / m2; De: planting density, unit, plant / m2; q: dripper flow, unit, L / h;

[0060] Producers input parameters such as planting crops, crop rotation, growth period, planting density and dripper flow into the water-fertilizer machine based on the planting situation.

[0061] The irrigation coefficient is pre-made according to the planting results of the previous test, and the irrigation coefficient of the specific crop in different growth periods is automatically determined. The producer can adjust the irrigation quota calculated by the model by using the water multiplier function. For example, the irrigation coefficient of spring tomato fruiting period is 3.0, the planting density is 3 plants / m2, the dripper flow is 2L / h, and the water multiplier is set to 1.0. When the light radiation accumulates to 100J / cm2, the single irrigation quota I=3*100*1=300mL / m2, and the single irrigation time T=60*300*10-3 / 3*2=3min, then the light radiation accumulates to 100J / cm2, and the single irrigation time is 3min.

[0062] In the machine learning parameter control, when the cumulative light radiation of the day reaches 700J / cm2, the current weather is judged to be sunny. The system calculates the average daily radiation based on the average light radiation of the past five sunny days. The average daily radiation value is automatically corrected once a month. The producer enters the number of daily irrigations and the duration of a single irrigation (min) according to the planting situation, and the system will automatically calculate the light radiation start threshold. For example, the average daily radiation in December is 735J / cm2. The producer hopes to irrigate twice a day, each time for 5 minutes. When the light radiation reaches 735 / 2=367.5J / cm2, irrigation is started for 5 minutes. The cumulative light speed on cloudy days slows down. If the light radiation start threshold is not reached, no irrigation is performed.

[0063] (b) Precision irrigation decision-making based on time series and soil moisture

[0064] (b1) Irrigation decision-making based on timing control means that irrigation is automatically started and stopped according to the irrigation start and end time set by the producer. The integrated water and fertilizer machine has three time periods and intervals, as well as an input port for a single irrigation duration. For example, if the producer sets the time from 8:00 to 12:00 in the morning, with an interval of 120 minutes and an irrigation time of 5 minutes, then the irrigation will be started twice at 10:00 and 12:00 respectively, and stopped at 10:05 and 12:05 respectively.

[0065] (b2) Irrigation decision based on soil moisture control: insert the soil moisture probe within 10cm of the crop root system, and manage irrigation according to the set upper and lower limits of soil moisture. For example, input irrigation when the soil volume moisture content is lower than 20%, and stop irrigation when it reaches 30%. This functional area also sets the allowed working time period and the all-day irrigation time limit. For example, if you input 8:00-16:00, irrigation will not be carried out outside this time period even if the irrigation lower limit of 20% is reached. Irrigation can only be started when entering the allowed working time period. For example, if you input 200min for the all-day irrigation time limit, the maximum allowed irrigation time per day is 200min, and even if the irrigation upper limit of 30% is not reached, irrigation will no longer be carried out.

[0066] (c) Precision fertilization decision-making

[0067] According to the nutrient requirements of crops, fertilizers are configured and dissolved in the fertilizer barrel. The nutrient solution in the fertilizer barrel is extracted by a fertilizer injection pump. The precise fertilization control based on proportional adjustment requires producers to input and define different fertilizer injection ratios for the three barrels A, B, and C. For example, if A is set to 50%, B is set to 30%, and C is set to 20%, then the fertilizer injection pump of barrel A runs at 50% speed, B at 30%, and C at 20%, thereby controlling the different fertilizer intake amounts of the three fertilizer barrels. The EC value refers to the concentration of soluble salts in a solution, and can also be used to represent the concentration of soluble ions in liquid fertilizers or planting media.

[0068] Based on EC value adjustment, the correlation model of EC value and nutrient solution concentration is prefabricated. According to the EC value input by the producer, the speed of the fertilizer injection pump is automatically adjusted. According to the PH value input by the producer, the fertilizer absorption amount of the acid barrel (usually barrel C) is automatically adjusted. Different fertilizer absorption ratio input ends of A:B are also set. For example, if it is set to 2.0, it will ensure that under the premise that the EC value reaches the input value, the fertilizer injection amount of barrel A is twice that of barrel B.

[0069] The producer inputs the fertilization time and flushing time according to the planting needs, but the fertilization time must be less than or equal to the irrigation time. For example, if the irrigation time is 10 minutes, the fertilization time is 10 minutes, and the flushing time is 1 minute, then irrigate with nutrient solution for 10 minutes, and then irrigate with clean water for 1 minute to flush the pipe.

[0070] (d) The integrated water and fertilizer machine uses a 10-inch touch screen, with a clear control interface and simple functions. It is mainly divided into two sections: the display area and the control area. The display area includes four aspects: irrigation strategy, fertilization strategy, fertilization master control machine information and comprehensive information. Irrigation decisions can choose light radiation, timing, soil moisture or manual control. The fertilization strategy displays the parameter settings related to fertilization, including fertilization time, flushing time, adjustment method, EC setting value, PH setting value and AB fertilizer ratio. The fertilization master control machine information displays the flow rate and daily flow of the main line, channel A, channel B, and channel C, as well as the current real-time EC and PH values. The comprehensive information is real-time data of air temperature, air humidity, substrate temperature, substrate humidity, light intensity, daily cumulative radiation, daily irrigation times and daily irrigation time. The control area mainly includes five functional areas: irrigation settings, fertilization settings, history records, system settings and lock screen, which can realize functions such as irrigation and fertilization parameter settings and historical record query of the operation of the integrated water and fertilizer machine.

[0071] The optical intelligent water-fertilizer integrated machine based on machine learning mainly includes three aspects: fertilization components, monitoring components and control components. The fertilization components mainly include three fertilizer barrels ABC, fertilizer injection pumps and filters, etc. The monitoring components mainly include light probes for measuring light radiation and probes for detecting soil moisture. The control component is the main body of the fertilization master control machine, which is responsible for collecting monitoring data such as light and soil moisture and issuing irrigation and fertilization instructions. According to the irrigation and fertilization parameters set by the producer, it controls the start and stop of the fertilizer injection pump and the solenoid valve.
