[0039] See also Figures 1 to 3The present invention discloses an integrated irrigation device for water, fertilizer, pesticide, and aeration, which is mainly used for planting crops such as corn. The integrated irrigation device includes an irrigation pipe assembly 100, an irrigation system 200, a fertilization system 300, a pesticide spraying system 400, and a ventilation system 500. The irrigation pipe assembly 100 is buried in the soil. The irrigation system 200 is connected to the irrigation pipe assembly 100 and is used to transport irrigation water to the irrigation pipe assembly 100. The fertilization system 300 is connected to the irrigation pipe assembly 100 and is used to transport liquid fertilizer to the irrigation pipe assembly 100. The pesticide spraying system 400 is connected to the irrigation pipe assembly 100 and is used to transport herbicide to the irrigation pipe assembly 100. The ventilation system 500 is connected to the irrigation pipe assembly 100 and is used to transport ventilation gas to the irrigation pipe assembly 100.

[0040] It can be understood that the infiltration irrigation pipe assembly 100 is buried in the soil, the irrigation system 200 is connected to the infiltration irrigation pipe assembly 100, and is used to transport irrigation water to the infiltration irrigation pipe assembly 100. Through the precise irrigation methods of infiltration irrigation and drip irrigation, water is directly transported to the roots of crops, reducing water evaporation and leakage, and significantly improving the utilization rate of irrigation water. The ventilation system 500 is connected to the infiltration irrigation pipe assembly 100 and is used to transport ventilation gas to the infiltration irrigation pipe assembly 100. The gas is directly introduced into the soil, alleviating the problem of water and gas imbalance in the soil after irrigation. The fertilization system 300 is connected to the infiltration irrigation pipe assembly 100 and is used to transport liquid fertilizer to the infiltration irrigation pipe assembly 100. The spraying system 400 is connected to the infiltration irrigation pipe assembly 100 and is used to transport herbicide to the infiltration irrigation pipe assembly 100. Therefore, liquid fertilizer and herbicide can be accurately prepared according to the crop growth stage and soil nutrient status, and directly transported to the crop roots through the irrigation system 200, thereby improving the utilization rate of fertilizer and herbicide.

[0041] In this embodiment, irrigation system 200 includes a water reservoir 210, a water level gauge, a pumping pipe 220, and a pump. One end of pumping pipe 220 extends into a well, and the other end communicates with water reservoir 210. The water level gauge is located in the well and is used to sense the water level therein. The pump is installed on pumping pipe 220 and is used to pump water into water reservoir 210. This arrangement allows for intermittent planned pumping of groundwater into water reservoir 210 when the groundwater level detected by the water level gauge is relatively stable, thereby avoiding damage to the groundwater ecosystem caused by large-scale pumping during a short period of time during the irrigation period.

[0042] It is understandable that the existing application of groundwater is basically to extract it when it is needed for irrigation and reduce extraction when it is not needed. However, such use will destroy the natural recharge balance of groundwater, easily lead to a sudden drop in water level and cause local subsidence.

[0043] While the water reservoir 210 of this embodiment cannot fully store the irrigation volume for corn cultivation, it can slowly and steadily extract groundwater. This method of use, on the one hand, minimizes groundwater level fluctuations, preventing large drops in the short term that could cause land subsidence. On the other hand, it reduces groundwater contaminants, improves groundwater purity, and reduces the chance of pipe and pump blockage failures.

[0044] In one embodiment, multiple water reservoirs 210 and multiple water level gauges are provided, one corresponding to each well. Multiple pumping pipes 220 are provided, one corresponding to each well, to pump water from each well into the corresponding water reservoir 210. Multiple pumping pumps are provided, each mounted on each pumping pipe 220; the pumping pumps can also pump water from the water reservoir 210 back into the well. This arrangement allows for adaptive deep-drilling of groundwater wells in corn-growing areas based on groundwater distribution, with corresponding water reservoirs 210 deployed.

[0045] It is understandable that, taking into account the location of the water storage tank 210 from the planting area and the groundwater well, the water storage tank 210 is set in a low-lying area to facilitate the collection of rainwater and the return of rainwater to the groundwater before the water storage tank 210 overflows.

[0046] Specifically, the water level meter is a pressure type water level meter, which measures the pressure of the water body on the pressure sensor to infer the groundwater level. The measuring range can reach 1000 meters. Furthermore, the water level meter can be optionally a silicon piezoresistive sensor, and the water level meter needs to be configured with triple lightning protection and IP68 waterproof design to ensure that it can work stably for a long time in a deep well. However, the water level meter also needs to be cleaned regularly to avoid mud and sand from clogging the sensor.

[0047] In one embodiment, see Figure 1 The irrigation system 200 also includes a first water pipe 230 and a first water pump 240. The infiltration irrigation pipe assembly 100 includes a plurality of infiltration pipe strips 110. The first water pipe 230 connects the water reservoir 210 and the plurality of infiltration pipe strips 110. The first water pump 240 is installed in the first water pipe 230 and is used to transport water from the water reservoir 210 to the plurality of infiltration pipe strips 110. The first water pipe 230 is also connected to a plurality of pumping pipes 220 and the plurality of infiltration pipe strips 110, so that water from the plurality of wells can be directly pumped to the plurality of infiltration pipe strips 110. With this arrangement, the soil in the corn planting area can be irrigated with water.

[0048] Specifically, the seepage tube belt 110 can be selected as an inner patch type seepage tube belt 110, and the flow rate of the seepage tube belt 110 is 2.2L / h-2.8L / h. Further, the flow rate of the seepage tube belt 110 can be selected as 2.2L / h, 2.3L / h, 2.4L / h, 2.5L / h, 2.6L / h, 2.7L / h or 2.8L / h.

[0049] In plain areas, the dripper operating pressure is 0.08-0.12 MPa. Furthermore, the dripper operating pressure can be selected to be 0.08, 0.09, 0.10, 0.11, or 0.12 MPa, and buried in the soil. On steep slopes or for long distances, the dripper operating pressure needs to be increased to 0.25-0.4 MPa to ensure uniform water flow from the dripper at the end of the infiltration tube strip 110.

[0050] Therefore, in order to ensure the rationality of the use of the seepage pipe strip 110, the irrigation system 200 also includes a pressure and flow monitoring element, which is arranged on the seepage pipe strip 110 and is used to sense the pressure and flow of the irrigation water, thereby controlling the operating power of the first water pump 240 according to the pressure and flow conditions to control the working pressure of the dripper.

[0051] In one embodiment, see Figure 1 The fertilization system 300 includes a second water pipe 310, a third water pipe 320, a fertilizer storage bin 330, and a mixing tank 340. The second water pipe 310 connects the water reservoir 210 and the mixing tank 340 to transfer water from the water reservoir 210 to the mixing tank 340. The fertilizer storage bin 330 is connected to the mixing tank 340 to allow granular fertilizer to be added to the mixing tank 340. The mixing tank 340 is used to mix the granular fertilizer with water to form liquid fertilizer. The third water pipe 320 connects the mixing tank 340 and the plurality of infiltration pipes 110. The second water pipe 310 also connects the plurality of pumping pipes 220 and the mixing tank 340 to transfer water from the well to the mixing tank 340. This arrangement allows granular fertilizer to be converted into liquid fertilizer for easy transport to the infiltration pipes 110.

[0052] It is understood that liquid fertilizer, prepared from granular fertilizer, offers advantages over liquid fertilizer as a fertilizer source. Solid granular fertilizer, due to its stable physical form and resistance to volatilization or leakage, can be stored for extended periods in a dry environment at room temperature without the need for specialized storage facilities, resulting in lower storage costs. Furthermore, solid granular fertilizer, due to its high density and relatively small size, is easier to transport and carry, thus reducing logistics costs.

[0053] In one embodiment, see Figures 1 to 3 The integrated irrigation system for water, fertilizer, medicine, and gas also includes a conveyor belt 720. The fertilizer storage silo 330 is provided with a silo cavity 331 and a silo opening 332 connected to the silo cavity 331. The conveyor belt 720 is used to convey granular fertilizer to the silo opening 332 and drop the fertilizer into the silo cavity 331. The conveyor belt 720 replenishes the silo cavity 331 with granular fertilizer, reducing the cost of manual loading.

[0054] Furthermore, in this embodiment, a smoke and dust suction device 333 is provided on the top of the silo cavity 331, and the smoke and dust suction device 333 is used to exhaust air so that the silo cavity 331 is in a negative pressure state, thereby preventing fertilizer dust from leaking from other locations such as the silo opening 332 and affecting the working environment.

[0055] Furthermore, in this embodiment, a dropping channel 334 for guiding the dropping of granular fertilizer is provided in the silo cavity 331 , and the channel cross-sectional area of the dropping channel 334 gradually decreases from the silo opening 332 to the direction away from the silo opening 332 , thereby reducing the leakage of fertilizer dust from the silo opening 332 .

[0056] Furthermore, in this embodiment, a discharge port communicating with the mixing tank 340 is provided at the bottom of the silo chamber 331. A discharge roller 335 is provided at the discharge port. Rotation of the discharge roller 335 discharges the granular material into the mixing tank 340. Specifically, a detachable baffle plate 336 is also provided at the discharge port. One end of the baffle plate 336 is fixed to the wall of the silo chamber 331, while the other end is free. Rotation of the discharge roller 335 drives the granular material to push the baffle plate 336 aside, thereby conveying the granular material into the mixing tank 340 under the action of gravity. By controlling the rotation rate and transfer volume of the discharge roller 335, the speed and amount of granular material conveyed into the mixing tank 340 can be controlled. At the same time, the concentration of the liquid fertilizer can be adjusted based on the water level or amount within the mixing tank 340.

[0057] Specifically, the fertilizer storage bin 330 is further provided with an observation window 337 , through which the amount of fertilizer stored in the bin cavity 331 can be observed, thereby controlling the feeding status of the conveyor belt 720 .

[0058] In one embodiment, see Figure 1 The spraying system 400 includes a pressure differential spray tank, in which herbicide is prepared. The outlet end of the pressure differential spray tank is connected to the third water pipe 320 so that the herbicide can be transported to the plurality of infiltration pipe belts 110 along with the clean water, thereby achieving spraying and weeding.

[0059] In one embodiment, see Figure 1 The ventilation system 500 includes a fan 510 and an air duct 520. The air duct 520 connects the fan 510 and the third water pipe 320, so that the fan 510 can blow air to the plurality of infiltration pipe strips 110. The air is directly introduced into the soil, thereby alleviating the problem of water and air imbalance in the soil caused by irrigation. Specifically, the fan 510 can be a Roots blower 510.

[0060] In one embodiment, see Figure 1The integrated irrigation equipment of water, fertilizer, medicine and gas also includes a filtration system 600, which is arranged on the pumping pipe 220 and is used to filter the water in the well. The filtration system 600 is used to reduce impurities in groundwater and ensure the quality of irrigation water.

[0061] In this embodiment, the filtration system 600 is a gravel filter. As is well understood, unfiltered groundwater contains impurities that can easily clog the drip irrigation tape, leading to high repair and replacement costs and labor. Using a gravel filter can reduce over 95% of impurities from entering the irrigation system 200, ensuring proper operation. Furthermore, the improved cleanliness of filtered groundwater can reduce flow resistance by approximately 30%, resulting in a 20%-40% increase in irrigation efficiency.

[0062] Specifically, to prevent the filter system 600 from reducing its filtration flow or even clogging after long-term operation, a backwash pump 730 is provided between the filter system 600 and the water reservoir 210. The backwash pump 730 is used to backwash the filter system 600 with water from the water reservoir 210, thereby ensuring the filtration efficiency of the filter system 600. After the backwash, the water discharged from the filter system 600 can be discharged into the sedimentation tank.

[0063] Furthermore, the filtration system 600 can also be set upstream of the infiltration pipe belt 110 to filter the liquid fertilizer to prevent it from affecting the function of the infiltration pipe belt 110. For cleaning of the filtration system 600, the filtration system 600 can be cleaned after irrigating the corn planting field 3 to 4 times, especially after liquid fertilizer irrigation, to improve its utilization efficiency and service life.

[0064] In one embodiment, the integrated irrigation equipment for water, fertilizer, pesticide, and aeration also includes an environmental monitoring system and a control system. The environmental monitoring system is used to monitor environmental data of the planting area and is electrically connected to the control system. The control system is electrically connected to the irrigation system 200, the fertilization system 300, the spraying system 400, and the ventilation system 500, and is used to control the irrigation volume of the irrigation system 200, the fertilizer volume of the fertilization system 300, the spraying volume of the spraying system 400, and the ventilation volume of the ventilation system 500. The control system can monitor the irrigation, fertilization, spraying, and ventilation processes, achieving intelligent management. It is understandable that the regional groundwater level can be comprehensively judged through the arrangement of various water level gauges. Therefore, wells with relatively safe water levels can be given priority for pumping.

[0065] Specifically, the environmental monitoring system includes a thermometer, a hygrometer, and an NPK sensor. It senses soil temperature, moisture, and nutrient content in the growing area, enabling the control system to intelligently control irrigation, fertilization, spraying, and aeration based on the data measured by the environmental monitoring system.

[0066] In order to configure the control system's irrigation, fertilization, spraying and ventilation process control, the water-fertilizer-pesticide-gas integrated irrigation equipment also includes a number of solenoid valves 740, which are correspondingly arranged on each pipeline. Their on and off functions can control the flow and blocking of liquid in the pipeline, thereby configuring irrigation, fertilization, spraying and ventilation control, and enabling the common use of pipelines to save costs.

[0067] In one embodiment, the integrated water, fertilizer, medicine and gas irrigation equipment also includes a return pipe 710, which connects the end of the third water pipe 320 and the mixing tank 340. With this arrangement, after fertilization is completed, water can be added to the fertilizer tank to clean the pipeline system. The cleaned water is then transported back to the mixing tank 340 for storage through the return pipe 710 and output when it is needed to irrigate the planted corn.

[0068] The return pipe 710 of this embodiment is primarily used to monitor the soil moisture in the corn field. When the soil moisture is high, the liquid is temporarily stored in the mixing tank 340 instead of being cleaned and discharged. When the moisture in the corn field is insufficient, it is discharged for irrigation, thereby improving the utilization rate of water resources. The application of liquid fertilizer and irrigation water to the planting area requires comprehensive consideration of the soil environmental conditions in the corn planting area. If the humidity is high, the concentration of liquid fertilizer can be appropriately increased. If the humidity is low, the concentration of liquid fertilizer can be appropriately reduced. At the same time, it is also possible to choose to apply irrigation water before applying liquid fertilizer to ensure the utilization rate of the resources.

[0069] See also Figures 1 to 3 The embodiment of the present invention further discloses a method for using a water-fertilizer-pesticide-gas integrated irrigation device. The method is applicable to the water-fertilizer-pesticide-gas integrated irrigation device of any of the above embodiments. The water-fertilizer-pesticide-gas integrated irrigation device includes an infiltration irrigation pipe assembly 100, an irrigation system 200, a fertilization system 300, a spraying system 400, and a ventilation system 500. The infiltration irrigation pipe assembly 100 is buried in the soil. The irrigation system 200 includes a water reservoir 210, a water level gauge, a water pump 220, and a water pump. One end of the water pump 220 extends into a water well, and the other end is connected to the water reservoir 210. The method for using the device includes the following steps:

[0070] S830 : The irrigation system 200 delivers irrigation water to the irrigation pipe assembly 100 .

[0071] S840 : The fertilization system 300 delivers liquid fertilizer to the irrigation pipe assembly 100 .

[0072] S850 : The spraying system 400 delivers herbicide to the irrigation pipe assembly 100 .

[0073] S860 : The ventilation system 500 delivers ventilation gas to the irrigation pipe assembly 100 .

[0074] S870 , the water level gauge senses the water level in the well, and the water pump pumps water into the water storage tank 210 .

[0075] It can be understood that through the precise irrigation methods of infiltration irrigation and drip irrigation, water is directly delivered to the roots of crops, reducing water evaporation and leakage, and significantly improving the utilization rate of irrigation water. The ventilation system 500 delivers ventilation gas to the infiltration irrigation pipe assembly 100, and the gas is directly introduced into the soil, alleviating the problem of water and gas imbalance in the soil after irrigation. The fertilization system 300 delivers liquid fertilizer to the infiltration irrigation pipe assembly 100, and the spraying system 400 delivers herbicide to the infiltration irrigation pipe assembly 100, so that liquid fertilizer and herbicide can be accurately prepared according to the crop growth stage and soil nutrient status, and directly delivered to the roots of crops through the irrigation system 200, thereby improving the utilization rate of fertilizer and herbicide.

[0076] In addition, a water level meter is set in the well and is used to sense the water level in the well. A water pump is installed on the pumping pipe 220 to pump water into the water storage tank 210. With this arrangement, when the water level meter detects that the groundwater level is relatively stable, groundwater can be intermittently pumped into the water storage tank 210 for storage, so as to avoid the damage to the groundwater ecosystem caused by large-scale groundwater extraction in a short period of time during the irrigation period.

[0077] In one embodiment, the integrated water, fertilizer, pesticide, and aeration irrigation device further includes an environmental monitoring system and a control system. The environmental monitoring system is electrically connected to the control system, and the control system is electrically connected to the irrigation system 200, the fertilization system 300, the pesticide spraying system 400, and the ventilation system 500. Before step S830, the method of use further includes the following steps:

[0078] S810. The environmental monitoring system monitors environmental data of the planting area.

[0079] S820 , the control system controls the irrigation amount of the irrigation system 200 , the fertilizer amount of the fertilizer system 300 , the spraying amount of the spraying system 400 , and the ventilation amount of the ventilation system 500 .

[0080] It is understandable that the control system can monitor the processes of irrigation, fertilization, spraying and aeration to achieve intelligent management. Through the arrangement of various water level gauges, the regional water level of groundwater can be comprehensively judged. Therefore, wells with safer water levels can be given priority for pumping.

[0081] Specifically, the environmental monitoring system includes a thermometer, a hygrometer, and an NPK sensor. It senses soil temperature, moisture, and nutrient content in the growing area, enabling the control system to intelligently control irrigation, fertilization, spraying, and aeration based on the data measured by the environmental monitoring system.

[0082] See also Figure 1The water-fertilizer-pesticide-gas integrated irrigation equipment and its use method of the present invention are used to integrate irrigation, fertilization, and pesticide application. At the same time, the irrigation control model, fertilization control model, and spraying control model are integrated into the control system to realize the monitoring, collection, and recording of various regional environmental data. The control system remotely and automatically controls the irrigation amount, EC value, and precise regulation of pesticide spraying, as well as historical operation records.

[0083] The irrigation system 200 is primarily designed to provide the required water for field crops, ensuring soil moisture levels are within an optimal range. Combined with automatic control principles, it achieves controlled irrigation of corn fields and scientifically and rationally regulates soil water levels. The fertilization system 300 delivers liquid fertilizer directly to the roots of corn crops, promoting nutrient absorption. The spraying system 400 utilizes a small, differential-pressure spray tank, which, through a seepage tube 110, enables precise and safe application of herbicides. Available herbicides include pyraclostrobin and acetochlor, atrazine, and 2,4-D ...

[0084] Take corn cultivation in eastern Inner Mongolia as an example.

[0085] First of all, corn is usually sown in early May, when the soil temperature is suitable, which is conducive to seed germination.

[0086] Afterwards, precision irrigation is carried out using integrated irrigation equipment for water, fertilizer, pesticides, and aeration. A reasonable irrigation plan is developed based on rainfall, soil moisture, and the corn's growth stage. Generally, within three days after sowing, a 110 drip irrigation system with a percolation tube is connected and a rate of 15-20 cubic meters per mu (approximately 5 cm) of water is applied, ideally moistening the seed row to approximately 5 cm above the sown line. Increase the frequency and volume of irrigation during key growth stages (e.g., jointing, tasseling, etc.).

[0087] Precision fertilization is performed using integrated irrigation equipment that combines water, fertilizer, pesticide, and aeration. A scientific fertilization plan is developed based on soil nutrient status and corn growth requirements. Seed fertilizer dosages include 3-5 kg / mu of pure nitrogen, 5-7 kg / mu of pure phosphorus, and 3-5 kg / mu of pure potassium. Topdressing dosages include 15-17 kg / mu of pure nitrogen, 3-5 kg / mu of phosphorus, and 5-7 kg / mu of potassium. Fertilizer is applied along with water through the irrigation system 200°, improving fertilizer utilization.

[0088] Integrated irrigation equipment for water, fertilizer, pesticides, and aeration is used for pesticide application management. The Spray System 400 precisely applies herbicides, insecticides, and fungicides based on the corn's growth stage and pest and disease occurrence.

[0089] Aeration management is performed using integrated irrigation equipment that combines water, fertilizer, pesticide, and aeration. The aeration system 500 ventilates the soil to alleviate soil moisture and gas imbalances caused by irrigation. Especially after heavy rainfall or irrigation, timely aeration promotes soil respiration and corn root growth.

[0090] Through such settings, the use of integrated water, fertilizer, medicine and gas irrigation equipment can achieve efficient, precise and sustainable development of corn planting in eastern Inner Mongolia.

[0091] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
