    Integrated agricultural irrigation and fertilizer application system
    TECHNICAL FIELD The present invention relates to the field of agricultural irrigation technologies, and specifically, to an integrated agricultural irrigation and fertilizer application system.
    BACKGROUND Methods of agricultural irrigation can be generally divided into the traditional surface irrigation, the ordinary sprinkler irrigation, and the micro-irrigation. The traditional surface irrigation comprises border strip irrigation, furrow irrigation, basin irrigation, and flood irrigation, which often consume a lot of water and have low water utilization efficiency; so, they are a type of very unreasonable agricultural irrigation methods. The ordinary sprinkler irrigation is a popular irrigation method in agricultural production in China, but its water utilization efficiency is also low. The modern agricultural micro- irrigation comprises micro-sprinkler irrigation, drip irrigation, infiltration irrigation, etc. These irrigation technologies generally have good water-saving performance and higher water utilization efficiency compared with the traditional irrigation methods. Fertilizer application can also be carried out in the irrigation process. The process of fertilizers entering the field with irrigation water is called irrigation fertilizer application. Specifically, in the process of irrigation, such as drip irrigation, subsurface drip irrigation, etc., the fertilizers are accurately supplemented and evenly applied to near the root system according to the nutrient needs at various growth stages of the crop and the climatic conditions to be directly absorbed and utilized by the root system. However, the internal pipeline and the emitters of the existing integrated agricultural irrigation and fertilizer application system are easy to be blocked. So, it is necessary to improve the existing technology to solve the above problems.

Sprinkler irrigation pipes 13 and drip irrigation pipes 14 are respectively connected with the upper side and the lower side of the irrigation branch pipe 12; a plurality of equidistantly distributed nozzles 15 are arranged at the bottoms of the sprinkler irrigation pipes 13, and a plurality of equidistantly distributed emitters 16 are arranged at the bottoms of the drip irrigation pipes 14. The acid solution tank 19 is communicated with the irrigation main pipe 9 through an acid feeding pipe 21, and an acid feeding pump 22 is arranged on the acid feeding pipe 21. The chlorine solution
    - 6 — tank 20 is communicated with the irrigation main pipe 3 through a chlorine feeding pipe 23, and a chlorine feeding pump 24 is arranged on the chlorine feeding pipe 23. The hydrogen peroxide tank 25 is communicated with the irrigation branch pipe 12 through a hydrogen peroxide feeding pipe 26, and a hydrogen peroxide feeding pump 27 is arranged on the hydrogen peroxide feeding pipe 26. Further, there are three fertilizer tanks 3. Top inlets of the three fertilizer tanks 3 are comunicated with the second water delivery pipe 7. The bottoms of the fertilizer tanks 3 are communicated with the irrigation main pipe 9 through fertilizer delivery pipes 17. A stirrer is arranged in each fertilizer tank 3 to uniformly stir the fertilizers in a fertilizer applying process. The fertilizer tanks 3 and the water tank 1 are connected by the second water delivery pipe
    7. So, a mixed fertilizer solution can be prepared from the clean water in the water tank 1 and the fertilizer. The preparation of the fertilizer is also convenient. Further, there are multiple sprinkler irrigation pipes 13 and multiple drip irrigation pipes 14, and the multiple sprinkler irrigation pipes 13 and the multiple drip irrigation pipes 14 are respectively equidistantly arranged on the irrigation branch pipe 12 in parallel. The water can be sprayed from the nozzles 15 to irrigate the leaves of the crops and can also be dripped from the emitters 16 to irrigate the roots of the crops. So, drip irrigation, sprinkler irrigation, or their combination can be selected as required. Further, a flush valve 18 is arranged at the end part of the other end of the irrigation main pipe 9. The flush valve 18 can be externally connected with a flushing device to flush the system. Further, the acid solution tank 19 is arranged at the upstream of the chlorine solution tank 20. When the pH value of the chlorine solution is higher than 7.0, the chlorine solution basically is ineffective; so, it is necessary to conduct the acid treatment by the acid solution tank 19 to complete the chlorine treatment downstream. Additionally, the acid solution tank 19 and the chlorine solution tank 20 are arranged at the upstream of a connection part of the fertilizer delivery pipes
    - 7 = 17 and the irrigation main pipe 3.

    Specific using steps of the system are as follows: Sl: The first water pump 6 pumps water {from the water collecting tank 2 to the water tank 1 for later use, and the water is filtered by the primary filter 5.
    S2: When the crops need to be irrigated, the third water pump 10 starts. Under the action of the third water pump 10, the water in the water tank 1 {flows into the secondary filter 11 through the irrigation main pipe 3 to be filtered. The filtered water flows into the sprinkler irrigation pipes 13 and the drip irrigation pipes 14 through the irrigation branch pipe 12, and then is sprayed through the nozzles 15 to irrigate the leaves of the crops and dripped through the emitters 16 to irrigate the roots of the crops. Drip irrigation, sprinkler irrigation, or their combination can be selected as required.
    S3: When the crops need fertilizer application, a mixed fertilizer solution is prepared. The second water pump 8 pumps the clean water from the water tank 1 to the fertilizer tanks 3. Solid fertilizers are putted into the fertilizer tanks 3 to form mixers. The stirrers mix the mixers uniformly to obtain the mixed fertilizer solutions. The third water pump 10 starts. Under the action of the third water pump 10, the mixed fertilizer solutions in the fertilizer tanks 3 flow into the secondary filter 11 through the irrigation main pipe 9 to be filtered. The filtered fertilizer solution flows into the drip irrigation pipes 14 through the irrigation branch pipe 12, and then is dripped through the emitters 16 to apply the fertilizers to the roots of the crops.
    - 8 - S4: After the system is used for a period of time, organic sediments generated by bacteria, slime bacteria, and algae in the pipes need to be treated. The acid treatment is conducted firstly. A qualified acid solution is prepared in the acid solution tank 19, wherein the pH value is reduced in the range of 5 and 6. The acid feeding pump 22 {feeds the prepared acid solution into the system. Next, the chlorine treatment is conducted. The chlorine feeding pump 24 feeds the chlorine treatment solution into the system until 1-3 ppm of available chlorine can be measured from the liquid dripped by the emitters 16. Then, the interior treatment of the pipes and the emitters 16 can be conducted.
    S5: When the conventional chlorine treatment is ineffective, the problem may be solved by utilizing hydrogen peroxide. The hydrogen peroxide has the better effect to treat the sediments in the pipes compared with the chlorine. The hydrogen peroxide feeding pump 27 feeds the hydrogen peroxide into the system. The hydrogen peroxide keeps feeding, and 100 ppm of the hydrogen peroxide treatment solution can be obtained from feeding points until the liquid dripped by the emitters 16 starts bubbling. Then, the interior treatment of the pipes and the emitters 16 can be conducted.
    Working principle is as follows: the system can simultaneously have the irrigation function and the fertilizer application function due to the arrangement of the water tank 1 and the multiple fertilizer tanks 3. The integrated design helps the whole system easy to be maintained. The agricultural irrigation and fertilizer application is simpler.
    Additionally, the fertilizer tanks 3 and the water tank 1 are connected by the second water delivery pipe 7; so, the clean water in the water tank 1 can be used for preparing the mixed fertilizer solution, and the preparation of the fertilizer is also convenient. Furthermore, the primary filter 5 and the secondary filter 11 are arranged. When the main pipeline is broken, or fine sands passing through the primary filter 5 gather to form larger grains to cause a latent blockage
    - 9 — threat, the secondary filter 11 plays an important role. The primary filter 5 and the secondary filter 11 match with each other to greatly filter impurities in the water and help the pipes, the nozzles 15, the emitters 16, etc. to be unblocked. Moreover, the sprinkler irrigation pipes 13, the drip irrigation pipes 14, the nozzles 15, and the emitters 16 are arranged. In the fertilizer applying process, the fertilizers can be applied to the roots of the crops through the emitters
    16. In the irrigating process, the water can be transported to the roots of the crops through the emitters 16 to irrigate the crops, and can also be sprinkled onto the leaves of the crops through the nozzles 15 to conduct sprinkler irrigation on the crops. So, drip irrigation and sprinkler irrigation are combined to improve the irrigation effects. And, the acid solution tank 19, the chlorine solution tank 20, and the hydrogen peroxide tank 25 are arranged to prevent the system from blocking. After the system is used for a period of time, the organic sediments generated by bacteria, slime bacteria, and algae in the pipes can be treated by chemical agents to avoid blockage.
