Description

Technical Field

[0001] The invention relates to the technical field of irrigation, and in particular to a water, fertilizer and gas integrated irrigation system and an irrigation method. Background Art

[0002] Integrated water-fertilizer technology is a new agricultural technology that combines irrigation and fertilization. It can be designed according to the water and fertilizer requirements of crops in different growth periods, and provide water and nutrients directly to crops in a timely, quantitative and proportional manner, with significant effects in saving water and fertilizer.

[0003] However, in actual use, fertilizers will promote sediment flocculation and sedimentation, and will adhere to the drip irrigation belt and the side walls of the drip irrigation emitter, causing the irrigation system to be blocked. In addition, for underground drip irrigation, since underground drip irrigation will generate negative pressure, the negative pressure will suck the soil into the drip irrigation pipe, which will further cause blockage and seriously affect the normal use of the drip irrigation system.

[0004] At present, the main anti-clogging measures for emitters are to optimize the flow channel structure of the emitter or add acid to the water source to dredge the pipe. However, the cost of optimizing the flow channel structure is high, and the acid treatment will also have an impact on the environment.

[0060] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

For ordinary workers in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0064] The integrated water and fertilizer technology is a new agricultural technology that integrates irrigation and fertilization. It can design the needs of different growth periods according to the water and fertilizer requirements of crops, and provide water and nutrients to crops directly in a timely and quantitative manner in proportion, with significant water and fertilizer saving effects. However, in actual use, fertilizers will promote sediment flocculation and sedimentation, and will adhere to the drip irrigation belt and the side walls of the drip irrigation emitter, causing the irrigation system to be blocked. In addition, for underground drip irrigation, since underground drip irrigation will generate negative pressure, the negative pressure will suck the soil into the drip irrigation pipe, which will further cause blockage and seriously affect the normal use of the drip irrigation system. At present, the anti-blocking measures for emitters mainly adopt the optimization of the emitter flow channel structure, or the addition of acid to the water source to dredge the pipe. However, the cost of optimizing the flow channel structure is high, and the acid treatment will also have an impact on the environment.

[0065] Moreover, in the current water-fertilizer integrated equipment, the irrigation and fertilization equipment are basically installed and arranged in a dispersed manner at the irrigation head. Some water-fertilizer integrated systems only integrate the water and fertilizer control system, but do not integrate the equipment with different functions, occupy a large area, and are not convenient for transfer.

[0066] In view of this, the present invention provides a water-fertilizer-gas integrated irrigation system and irrigation method to solve the problem of irrigation system blockage.

[0067] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.

[0068] According to an embodiment of the present invention, on the one hand, a water-fertilizer-gas integrated irrigation system is provided, the irrigation system comprising a support component 1, a water supply component 2, a fertilizer supply component 4, a micro-nano bubble component 5 and an electronic control component 6.

[0069] Specifically, in an embodiment of the present invention, the support assembly 1 may be a support frame. The support assembly 1 specifically includes a bottom plate, a plurality of pillars and a top plate. The bottom plate is a rectangular structure, and the four corners of the plane on the bottom plate are respectively fixedly connected to the bottom surfaces of the first pillar, the second pillar, the third pillar and the fourth pillar, and the first pillar, the second pillar, the third pillar and the fourth pillar are fixedly connected with a partition at the same height in the middle area, and the tops of the first pillar, the second pillar, the third pillar and the fourth pillar are all fixedly connected to the four corners of the top plate.

[0070] An accommodating cavity for installing equipment is provided between the top plate and the partition plate and between the partition plate and the bottom plate, and the accommodating cavity is provided with a water supply component 2, a fertilizer supply component 4, a micro-nano bubble component 5 and an electric control component 6. The water supply component 2, the fertilizer supply component 4, the micro-nano bubble component 5 and the electric control component 6 can be installed in the accommodating cavity in a modular form, so as to facilitate installation and maintenance by technicians.

[0071] Furthermore, in an embodiment of the present invention, the water supply component 2 is arranged on the support component 1. The water supply component 2 is provided with a water absorption component 3 and a water supply port 21, the water absorption component 3 is suitable for being connected to a water source, and the water supply port 21 is suitable for being connected to an irrigation pipe network. The water source can be irrigation water, or a natural water source such as a river or a stream. After the water absorption component 3 is connected to the water source, water can enter the water supply component 2 through the water absorption component 3, and then the water flows into the irrigation pipe network through the water supply port 21 to realize irrigation of farmland.

[0072] Further, in an embodiment of the present invention, a fertilizer supply component 4 is disposed on the support component 1, and the fertilizer supply component 4 is connected to the water absorption component 3. The fertilizer supply component 4 is used to store fertilizer liquid, and when it is necessary to fertilize the farmland, the fertilizer liquid is directly introduced into the water absorption component 3, so that it can enter the irrigation network at the same time as the irrigation water. When the fertilizer is stored in the fertilizer supply component 4, the fertilizer needs to be dissolved by water, so the fertilizer supply component 4 can be connected to a water source, so that the fertilizer supply component 4 can be introduced into the amount of water corresponding to the amount of fertilizer according to actual needs to ensure that the internal fertilizer can be completely dissolved.

[0073] Of course, this embodiment is only an example to illustrate the specific working mode of the fertilizer supply component 4, but it is not limited to this. Those skilled in the art can make changes according to actual conditions as long as the same technical effect can be achieved.

[0074] Further, in an embodiment of the present invention, the micro-nano bubble assembly 5 is provided with an inlet pipe 51 and an outlet pipe 52. The inlet pipe 51 and the outlet pipe 52 are both connected to the water supply assembly 2. In the actual working process, the micro-nano bubble assembly 5 inhales raw water from the water supply assembly 2 through the inlet pipe 51, then inhales air and mixes it with the raw water to generate bubble water, and then discharges the bubble water into the water supply assembly 2 through the outlet pipe 52. Therefore, the oxygen content of the irrigation water can be increased. During irrigation, the energy generated when the micro-nano bubbles burst can be used to flush the irrigation system and the irrigation network, thereby enhancing the anti-clogging performance of the emitter, and the micro-nano aeration does not affect the uniformity of the irrigation.

[0075] Further, in the embodiment of the present invention, the electronic control component 6 is simultaneously connected to the water supply component 2, the fertilizer supply component 4 and the micro-nano bubble component 5. The technician can control the operation of the water supply component 2, the fertilizer supply component 4 and the micro-nano bubble component 5 through the electronic control component 6.

[0076] In this way, the embodiment of the present invention can flush the border of the sprinkler and the drip irrigation network by setting the micro-nano bubble component 5, using the energy generated when the micro-nano bubble bursts, thereby enhancing the anti-clogging performance of the sprinkler, and the micro-nano gasification does not affect the uniformity of the irrigation. Therefore, there is no need for acid treatment, reducing the cost of optimizing the pipeline, and avoiding the impact on the environment. In addition, this embodiment integrates the irrigation, fertilization, and gasification systems and structures into one, and uses them as a water supply device in the field, reducing the floor space, enhancing the mobility of the equipment, and realizing the synchronous irrigation of water, fertilizer, and gas. At the same time, this embodiment can use the electronic control component 6 to achieve quantitative irrigation and variable fertilization, and can flexibly adjust the fertilizer concentration by controlling the fertilizer supply component 4, thereby improving the utilization rate of water and fertilizer. It is also possible to adjust the water-fertilizer-gas ratio, fertilizer type, and supply amount according to specific needs, save water and fertilizer, and have better adaptability to meet the different needs of different stages in crop growth.

[0084] Furthermore, the fertilizer suction pipeline 42 is connected to the fertilizer suction box 41; the fertilizer suction pipeline 42 corresponds to the fertilizer suction box 41 one by one. That is, each fertilizer suction box 41 corresponds to a fertilizer suction pipeline 42, and when three fertilizer suction boxes 41 are provided, three fertilizer suction pipelines 42 are also provided accordingly.

[0085] Furthermore, one end of the fertilizer mixing pipe 43 is connected to the fertilizer absorption pipeline 42 , and the other end of the fertilizer mixing pipe 43 is connected to the water absorption component 3 .

[0086] In this way, by setting up multiple fertilizer suction boxes 41 in the embodiment of the present invention, the user can replace and add multiple fertilizers according to the actual needs of the crops during use, thereby adapting to the different needs of different stages of crop growth.
