Description

Technical Field

[0001] This invention relates to a digital irrigation system for horticultural crops in mountainous areas, and more particularly to a drip irrigation cultivation device for a digital irrigation system for horticultural crops in mountainous areas applied in the field of irrigation. Background Technology

[0002] For a long time, mountain agriculture has suffered from water scarcity and insufficient irrigation water, making water a major constraint in the development of mountain agriculture. As a result, drip irrigation technology has been adopted, but existing drip irrigation systems cannot be remotely controlled.

[0003] To address the issue of the inability to remotely control existing drip irrigation technologies, a certain irrigation system on the market employs a remote-controlled drip irrigation design, and has achieved a certain market share.

[0004] Chinese invention patent CNC16349473A discloses an automatic drip irrigation and fertilization system for forest seedlings. The patent uses a remote control mobile device and an integrated water and fertilizer machine, allowing personnel cultivating seedlings to remotely control the drip irrigation water for the seedlings and the top dressing of the land.

[0005] However, during the drip irrigation process, the rudimentary seedling cultivation equipment and poor control of the drip irrigation volume can easily cause local waterlogging, thereby affecting the survival of seedlings and root growth.

[0006] Application content

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to effectively prevent local waterlogging during drip irrigation.

[0008] To address the aforementioned problems, this invention provides a digital irrigation system for horticultural crops in mountainous areas, comprising an intelligent control cloud platform. The intelligent control cloud platform includes a remote control module, a soil moisture monitoring module, an environmental monitoring module, and an irrigation module. The remote control module includes a wireless gateway and a signal receiver and transmitter. The soil moisture monitoring module includes a soil moisture sensor, which is connected to the intelligent control cloud platform via the remote control module. The environmental monitoring module includes an air quality sensor and an air temperature and humidity sensor, which are also connected to the intelligent control cloud platform via the remote control module. The irrigation module includes multiple drip irrigation tapes laid among the crops in the mountains and a water and fertilizer solution preparation device placed on the mountaintop. All drip irrigation tapes are simultaneously connected to the water and fertilizer solution preparation device. Each drip irrigation tape has a drip head connected to its end, and a multi-media, bottomless root control cultivation tray for the cultivated crops is connected to the drip head. A porous root control plate is fixedly connected to the inner wall of the multi-media, bottomless root control cultivation tray. The top of the porous root control plate is filled with a non-soil substrate, and the bottom of the porous root control plate is filled with soil.

[0009] In the aforementioned digital irrigation system for horticultural crops in mountainous areas, a cultivation method combining soilless substrate in the early stage and soil in the later stage is achieved through multi-media trayless root control cultivation trays and porous root control boards, which effectively improves seedling survival rate and growth rate.

[0010] As a further improvement to this application, multiple drip irrigation tapes are laid from high to low along the mountain slope, and the multiple drip irrigation tapes are divided into zones according to the types of crops.

[0011] As a further improvement of this application, the water and fertilizer mixing device is connected to a main infusion pipe, and multiple infusion branch pipes are connected to the main infusion pipe. The drip irrigation tape in each zone is simultaneously connected to one infusion branch pipe, and a solenoid valve is installed on this infusion branch pipe.

[0012] As a further improvement of this application, the upper inner wall of the multi-media trayless root control cultivation tray is provided with an annular liquid storage cavity, and the upper end of the annular liquid storage cavity is provided with multiple insertion ports that match the drip irrigation head. The inner wall of the multi-media trayless root control cultivation tray is connected to multiple equally spaced and distributed drip tubes, and the drip tubes are connected to the interior of the annular liquid storage cavity.

[0013] As a further improvement of this application, the porous root control plate includes an upper plate and a lower plate, with a damping shaft rotatably connected between the middle of the upper plate and the lower plate, and multiple root limiting holes are provided on both the upper plate and the lower plate. An annular groove is provided on the upper side wall of the lower plate, and multiple sliding columns that are slidably connected to the annular groove are fixedly connected to the lower side wall of the lower plate.

[0014] As another improvement of this application, a hydraulic seal is fixedly connected to the inner wall of the annular liquid storage cavity. A sealing ball is provided above the hydraulic seal in the annular liquid storage cavity, and a leakage port that seals with the sealing ball is opened in the middle of the hydraulic seal. Fixing rods are fixedly connected between the two sides of the sealing ball and the inner wall of the annular liquid storage cavity.

[0015] As another improvement of this application, the hydraulic seal includes a lifting ring and a sealing ring, wherein the lifting ring is made of a flexible elastic material and the sealing ring is made of a hard, non-elastic material.

[0016] In summary, by using an intelligent control cloud platform and relying on wireless LAN connection technology, remote control and management of mountain crop cultivation and environmental data collection can be achieved. This data can then be used to control the irrigation module to precisely apply water and fertilizer to each crop. A multi-media, bottomless root-controlling cultivation tray and a porous root-controlling board enable a soilless substrate cultivation method for seedlings in the early stages and a combination of soil and water in the later stages. The multi-media, bottomless root-controlling cultivation tray provides further drip irrigation on top of the drip irrigation head, effectively preventing excessive drip irrigation water from causing localized waterlogging. Combined with the porous root-controlling board, the seedlings can slowly penetrate this area during the fruiting period, effectively preventing root rot and thus significantly improving seedling survival rate and growth rate.

Detailed Implementation

[0027] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] First implementation method:

[0029] Figure 7 , 8 The diagram shows an intelligent control cloud platform, which includes a remote control module, a soil moisture monitoring module, an environmental monitoring module, and an irrigation module. The remote control module includes a wireless gateway and a signal receiver and transmitter. The soil moisture monitoring module includes a soil moisture sensor, which is connected to the intelligent control cloud platform via the remote control module. The environmental monitoring module includes an air quality sensor and an air temperature and humidity sensor, which are also connected to the intelligent control cloud platform via the remote control module.

[0030] Figure 7 , 8The irrigation module shown includes multiple drip irrigation tapes laid among crops in the mountains and a water and fertilizer mixing device placed on the mountaintop. Multiple drip irrigation tapes are simultaneously connected to the water and fertilizer mixing device. The tapes are laid from high to low along the mountain slope and are divided into zones according to crop type. The mountainous terrain provides stable water pressure for precise drip irrigation, effectively solving the problem of power supply difficulties in mountainous areas and also contributing to energy conservation and emission reduction. The water and fertilizer mixing device is connected to a main infusion pipe, which in turn is connected to multiple branch pipes. Each drip irrigation tape in each zone is simultaneously connected to one branch pipe, and this branch pipe is equipped with a solenoid valve. Different types of crops have different drip irrigation requirements, so drip irrigation is carried out in zones according to crop type. Each zone's nodes are opened and closed via solenoid valves to achieve precise irrigation. The water and fertilizer mixing device uses water pressure to deliver nutrient solution to each drip irrigation tape, achieving zero-energy irrigation in the process.

[0031] Figure 1 , 2 and Figure 5 The diagram shows that each drip irrigation tape is connected to a drip head at its end, and a multi-media, bottomless root control cultivation tray 1 for the cultivated crop is connected to the drip head. A porous root control plate 2 is fixedly connected to the inner wall of the multi-media, bottomless root control cultivation tray 1. The upper part of the porous root control plate 2 is filled with a non-soil substrate, and the lower part of the porous root control plate 2 is filled with soil. An annular liquid storage cavity 101 is opened on the upper inner wall of the multi-media, bottomless root control cultivation tray 1, and multiple insertion ports 102 that match the drip head are opened at the upper end of the annular liquid storage cavity 101. Multiple equally spaced, circularly distributed drip tubes 3 are connected to the inner wall of the multi-media, bottomless root control cultivation tray 1, and the drip tubes 3 are connected to the interior of the annular liquid storage cavity 101. The drip head first drips the nutrient solution into the annular liquid storage cavity 101, and then drips it into the soil near the crop roots through the drip tubes 3. The two drip irrigations can not only effectively prevent waterlogging caused by excessive drip irrigation, but also effectively prevent the nutrient solution from evaporating.

[0032] Second implementation method:

[0033] Figure 3 , 4The porous root control board 2 includes an upper plate 201 and a lower plate 202. A damping shaft 203 is rotatably connected between the middle of the upper plate 201 and the lower plate 202. Both the upper plate 201 and the lower plate 202 are provided with multiple root-limiting holes 204. An annular groove 205 is provided on the upper side wall of the lower plate 202, and multiple sliding columns 206 that are slidably connected to the annular groove 205 are fixedly connected to the lower side wall of the lower plate 202. The root-limiting holes 204 allow the roots to slowly break through this area, thereby achieving the purpose of root restriction. Moreover, since the soilless cultivation method is adopted above the porous root control board 2, the survival rate and growth rate of seedlings are effectively improved. In addition, by rotating the upper plate 201 and the lower plate 202, the size of the root-limiting hole 204 can be adjusted to achieve a further root-limiting effect, thereby meeting the root restriction needs of different crops and effectively expanding the application range of the porous root control board 2.

[0034] Figure 6 The inner wall of the annular liquid storage cavity 101 is also fixedly connected to a hydraulic seal 4. The hydraulic seal 4 includes a lifting ring 401 and a sealing ring 402. The lifting ring 401 is made of a flexible elastic material, and the sealing ring 402 is made of a hard, non-elastic material. The sealing ring 402 serves to seal by contacting the sealing ball 5. The elasticity of the lifting ring 401 ensures that the sealing ring 402 is in close contact with the sealing ball 5. When the weight of the nutrient solution exceeds the elasticity of the lifting ring 401, the sealing ring 402 moves downward and separates from the sealing ball 5, thereby achieving intermittent sealing between the hydraulic seal 4 and the sealing ball 5. The sealing ball 5 is located above the hydraulic seal 4 in the annular liquid storage cavity 101, and the hydraulic seal 4 has a sealing ball 5 located in the middle. The sealing ball 5 seals the leaking outlet. The two sides of the sealing ball 5 are fixedly connected to the inner wall of the annular storage cavity 101. When the drip irrigation head drips the nutrient solution into the annular storage cavity 101, the weight of the nutrient solution causes the hydraulic seal 4 to bend downwards and separate from the sealing ball 5. In this way, the nutrient solution above the hydraulic seal 4 flows down through the leaking outlet and then flows out from the drip tube 3. When the weight of the nutrient solution above is no longer enough to bend the hydraulic seal 4, the hydraulic seal 4 re-seales with the sealing ball 5. This repeated sealing and separation of the hydraulic seal 4 and the sealing ball 5 causes the nutrient solution to flow downwards intermittently, thereby achieving the purpose of quantitative delivery and effectively preventing excessive drip irrigation from causing local flooding.

[0035] The working principle of this system is as follows: the water and fertilizer mixing device automatically mixes the nutrient solution according to the water pressure generated by the mountain terrain, and then delivers the nutrient solution to the drip irrigation tapes in various areas through the main and branch pipes. The intelligent remote control cloud platform analyzes and studies the data transmitted by the soil moisture sensor, air humidity sensor, and air quality sensor. The staff remotely controls the opening and closing of the solenoid valve through the intelligent control cloud platform to carry out drip irrigation for different types of crops. The seedlings of the crops are cultivated in the multi-media bottomless root control cultivation tray 1. During drip irrigation, the drip head is inserted into the inlet 102, and the nutrient solution first drips into the annular liquid storage chamber 101. When the weight of the nutrient solution is greater than the elastic force of the hanging ring 401, the sealing ring 402 moves downward and separates from the sealing ball 5. At this time, the nutrient solution flows down through the leakage port and then out of the drip tube. 3. When the nutrient solution flows out, and the weight of the nutrient solution is less than the elasticity of the hanging ring 401, the hydraulic seal 4 will re-seal with the sealing ball 5. The repeated sealing and separation of the hydraulic seal 4 and the sealing ball 5 causes the nutrient solution to flow downward intermittently, thereby achieving the purpose of quantitative delivery and effectively preventing excessive drip irrigation from causing local waterlogging. In the early stage, the seedlings' roots are cultivated in a non-soil substrate, realizing soilless cultivation. In the later stage, the roots slowly break through the porous root control plate 2, and the root limiting hole 204 plays a role in root control. In the later stage, the seedlings' roots are cultivated in the soil, realizing the cultivation method of soilless substrate in the early stage and soil combination in the later stage, effectively improving the survival rate and growth rate of seedlings. Moreover, for different types of crops, the size of the root limiting hole 204 can be adjusted by rotating the upper plate 201 and the lower plate 202.

[0036] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
