The water pump 13 can draw water from the water source 12 into the water storage tank 15, but the water entering the water storage tank 15 will first pass through the water quality filter 14 to filter the water pumped by the water pump 13. There may be odors and impurities inside the unknown water source 12, and the water quality filter 14 can change the water quality. To make the water source 12 more in line with the irrigation needs, the water filter 14 includes a pretreatment screen 141, a coarse filter 142, a fine filter 143, an activated carbon filter 144, and an ozone generator 145 which are connected in sequence by pipelines. The pretreatment screen 141 is mainly used to perform preliminary treatment on the water entering the water storage tank 15, and screen out large particles of suspended matter, sediment, etc. The coarse filter 142 is mainly used for secondary removal of larger suspended matter, leaves, etc., which is convenient for secondary processing of preliminary treatment, convenient for subsequent water filtration and avoids clogging of subsequent filtration equipment. The fine filter 143 is mainly used to remove smaller suspended matter, microorganisms, organic matter, etc. in the water. The activated carbon filter 144 is mainly used to remove odors, pigments, organic matter and residual pesticides in the water, because the activated carbon has a relatively high Strong adsorption capacity can effectively improve the quality of water. The ozone generator 145 is mainly used to sterilize and disinfect water, remove bacteria, pathogens, etc. in the water. The water filter 14 improves and evolves water quality in a progressive manner to protect soil and plants from pollution and damage. The water storage tank 15 is a container for storing filtered water to ensure sufficient water resources for irrigation. The irrigator 16 is used to disperse the high-quality water resources in the water storage tank for irrigation. The water injection pipeline 11 is provided with a plurality of water injection branch pipelines 17. The irrigators 16 are evenly distributed on the water injection branch pipelines 17. The water injection pipeline 11 is provided with a total control water valve 18 and a water pressure gauge 19. The water pressure gauge 19 is used to detect the water pressure condition on the water injection pipeline 11. The water injection branch pipeline 17 is provided with a plurality of branch valves 18 and a water pressure gauge 19. The water pressure gauge 19 is used to detect the water pressure condition on the water injection pipeline 11. The pipeline controls the water valve 110, and the branch pipeline controls the water valve 110 to control the irrigation of the water resources on the water injection branch pipeline 17. The fertilization system 3 includes a fertilizer storage tank 32 and a fertilizer sprayer 33 connected through the fertilizer injection pipeline 31.

[0022] Furthermore, the pH value detection system 4 detects the pH value of the soil of the plant, because the pH value of the soil has a great influence on the absorption and effectiveness of trace elements. By measuring the pH value of the soil, the content of trace elements in the soil can be determined. The traditional sampling and spot testing method of measuring the pH value of the soil has low labor efficiency and a low overall mechanization level. The pH value detection system 4 can monitor the trace elements in the soil in real time, and the overall mechanization level is high. For large-scale crop planting, the pH value detection system 4 of the device has high practicality. The pH value detection system 4 includes a plurality of one-to-one corresponding electrochemical sensors 41, a maintenance device 42, and a signal amplification device. The electrochemical sensor 41 is a kind of device for detecting The sensor for measuring soil pH value can exist in the soil for a long time and does not need to be frequently replaced, thereby ensuring the authenticity and validity of the monitoring data. The electrochemical sensor 41 extends into the root system of the plant in the soil layer. Since the root system is the main part for crops to absorb nutrients, and the nutrients at the root system can better understand the characteristics of the soil in which the plants are located, placing the electrochemical sensor 41 close to the plant root system can more accurately detect the content of nutrients in the soil, perform location detection, meet the nutritional needs of the plants, and avoid excessive fertilization. The maintenance device 42 can maintain and calibrate the electrochemical sensor 41, ensure the accuracy, reliability and timeliness of the detection results of the electrochemical sensor 41, and ensure the timeliness and service life of the electrochemical sensor 41. The maintenance device 42 is located on the upper surface of the soil. The maintenance device 42 includes a cleaning liquid, a calibration liquid, a soaking liquid, and a scrubbing tool. The cleaning liquid can clean the turtles and impurities on the surface of the electrochemical sensor 41 to keep the surface of the electrochemical sensor 41 clean. The calibration liquid is used to calibrate the electrochemical sensor 41 to ensure the accuracy of the detection result. The soaking liquid is used to soak the electrochemical sensor 41. The soaking liquid is used to protect the electrodes of the electrochemical sensor 41 to ensure the overall service life of the electrochemical sensor 41. The scrubbing tool includes a common brush, a cotton swab, etc., which is mainly used to clean the surface of the electrochemical sensor 41 and clear the dirt inside the sensor to ensure that the device can be used normally and avoid the reduction of the detection accuracy during the service life. The signal amplification device is mainly for The signal collected by the electrochemical sensor 41 is amplified to enhance the stability and accuracy of the signal. The data of the soil pH value detected by the electrochemical sensor 41 is first amplified by the signal amplification device, and the amplified signal is transmitted to the water-fertilizer integrated machine 2. The water-fertilizer integrated machine 2 will obtain basic information about the soil according to the detected pH value, and then judge whether the soil needs further watering or fertilization. Watering and fertilization are controlled by several control valves on the water injection pipe 11 and the fertilizer injection pipe 31, including the amount of water and the amount of fertilizer. Based on the content of nutrient elements at the soil root system detected by the pH value detection system 4, more accurate watering or fertilization is further performed, and the overall planting is more scientific.The degree of mechanization of planting is higher, which is suitable for planting of different areas, and for growers planting on a large area, the overall difficulty of breeding is greatly reduced.
