Technical Field
[0001] This utility model relates to the field of drip irrigation technology for wheat and corn, and in particular to a drip irrigation device for wheat and corn intercropping with separate control of water and fertilizer. Background Technology
[0002] Wheat-corn intercropping is a planting technique that combines wheat and corn on the same plot of land. Its core significance lies in achieving efficient resource utilization, ecological balance, and improved economic benefits through the synergistic effect between crops. Wheat is a short-stalked crop, while corn is a tall-stalked crop. The combination of the two forms a "high-low stratified" structure, which allows for the stratified utilization of light resources. This improves resource efficiency, but it also places new demands on drip irrigation technology.
[0003] In common wheat-corn intercropping drip irrigation systems, the drip irrigation holes on the drip tape or pipe are usually evenly distributed, with uniform hole size and spacing. This makes it impossible to flexibly adjust the system according to the different planting densities, row spacing, and root distribution characteristics of wheat and corn. As two crops with significantly different growth characteristics, wheat and corn have significantly different water and nutrient requirements when intercropped. Wheat plants are shorter and have a smaller root distribution area, while corn plants are taller, have a more developed root system, and require more water. If conventional drip irrigation systems are used for uniform irrigation, it often results in either excessive water supply to the wheat area or insufficient water supply to the corn area, leading to a waste of water and fertilizer resources and even affecting the normal growth of the crops.
[0004] Therefore, in view of the problem that the above-mentioned wheat-corn intercropping drip irrigation device cannot adjust the drip irrigation position according to the planting density and root distribution characteristics, there is an urgent need to design a new type of wheat-corn intercropping water and fertilizer separate control drip irrigation device. Utility Model Content
[0005] To overcome the problem that common drip irrigation devices for wheat-corn intercropping cannot adjust the drip irrigation position according to planting density and root distribution characteristics.
[0006] The technical solution of this utility model is as follows: a drip irrigation device for wheat-corn intercropping with separate water and fertilizer control, including a drip irrigation pipe; and sealing cover plates respectively installed at both ends of the drip irrigation pipe. The sealing cover plates are used to seal both ends of the drip irrigation pipe. Two mounting blocks are connected to the outer side of the sealing cover plates. Insert rods are installed at the lower ends of the mounting blocks. The separate control component includes a fixing rod, a separating module, a distribution module, a cavity module, a connecting module, a transport module, and a drip irrigation module set inside the drip irrigation pipe. The separating module is used to separate the internal cavity of the drip irrigation pipe. The distribution module is responsible for guiding water into the corresponding internal cavity of the drip irrigation pipe. The cavity module serves as a buffer cavity area for the distribution module. The connecting module is used to install the transport module. The transport module is responsible for transporting external drip irrigation water into the drip irrigation pipe. The drip irrigation module is used for drip irrigation. The insert rod is used to fix the entire drip irrigation pipeline to the ground.
[0007] Preferably, the drip irrigation pipe is used to transport and distribute the water-fertilizer mixture. Sealing caps are installed at both ends to seal the pipe and prevent leakage. Mounting blocks are located on the outside of the sealing caps for connecting rods, which can then be used to fix the entire drip irrigation pipe in the field for stability. A fixing rod is installed inside the drip irrigation pipe to support the internal structure. A partition module divides the inside of the drip irrigation pipe into four independent chambers for zoned control. A distribution module is responsible for guiding the water flow into the corresponding chambers, facilitating precise control according to the needs of different crops. The partition module acts as a water flow buffer, making the water pressure more stable. A connecting module is connected to the partition module for installing the transport module. The drip irrigation module consists of four rows of drip irrigation holes with different spacing and diameters, corresponding to the four chambers. It can precisely control the water outlet position and flow rate based on the planting density and root distribution characteristics of wheat and corn, meeting the differentiated irrigation needs of intercropping.
[0008] Preferably, the dividing module includes a partition installed on the outer side of the fixing rod, which divides the interior of the drip irrigation tube into four spaces.
[0009] Preferably, the distribution module includes four valves installed on the surface of the left sealing cover, each valve connecting to one of the four cavities inside the corresponding drip irrigation tube.
[0010] Preferably, the cavity module includes a connecting cover mounted on the surface of the left sealing cover plate, the connecting cover forming a cavity between the sealing cover plates, and the cavity of the connecting cover being used to interconnect the four paths of the valve.
[0011] Preferably, the connecting module includes a connector disposed on the left end face of the connecting cover, and the connector communicates with the cavity of the connecting cover.
[0012] Preferably, the transport module includes a hose installed inside the connector, which is responsible for transporting external drip irrigation water into the drip irrigation pipe.
[0013] Preferably, the drip irrigation module includes drip irrigation holes formed on the surface of the drip irrigation pipe, the drip irrigation holes are arranged in four rows, and the rows of drip irrigation holes maintain different intervals and different diameters, with the four rows of drip irrigation holes corresponding to different cavities of the drip irrigation pipe.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting a partition inside the drip irrigation pipe, it is divided into four independent chambers and equipped with four sets of independently adjustable valves. Four rows of drip irrigation holes are arranged axially on the surface of the drip irrigation pipe. Each row of drip irrigation holes has a different spacing and diameter. According to the row spacing, planting density and root distribution characteristics of wheat and corn in intercropping, the corresponding chamber and drip irrigation hole row can be selectively activated to match the water and fertilizer requirements of the crop, thereby effectively adapting to the irrigation needs of various wheat and corn intercropping patterns.
[0016] 2. The buffer cavity formed between the connecting cover and the sealing cover can play a role in stabilizing pressure and buffering, effectively reducing water flow impact and pressure fluctuation, ensuring stable water supply to each chamber, and improving the uniformity and consistency of overall irrigation.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] With global climate change and population growth, agricultural production faces unprecedented challenges. To increase crop yields while reducing environmental impact, agricultural technologies are constantly evolving and innovating. Wheat-corn intercropping, as a resource-efficient method, achieves diversified crop cultivation on limited land, improving land utilization and economic benefits. However, traditional irrigation and fertilization methods struggle to meet the varying water and nutrient requirements of different crops, limiting the full potential of intercropping systems. Therefore, developing a precise drip irrigation system for wheat-corn intercropping, capable of controlling water and fertilizer supply, is crucial. Traditional flood irrigation methods... Not only is water use inefficient, but it also easily leads to soil compaction, affecting root growth. Inappropriate fertilization strategies can result in significant fertilizer loss through runoff, increasing costs and polluting the environment. Wheat and corn have significantly different water and nutrient requirements during their growth cycles, making it difficult to meet both needs with a uniform irrigation and fertilization plan. For large-scale farmland, implementing refined management is challenging and labor-intensive. In recent years, with the growing popularity of water-saving agriculture and advancements in modern agricultural technology, integrated water and fertilizer management technology has been widely applied and developed. This technology organically combines irrigation and fertilization to ensure the necessary nutrients for crop growth. At the same time, to maximize resource conservation, for wheat-corn intercropping, the use of a specially designed water and fertilizer controlled drip irrigation system can achieve the following goals: It adjusts the water and fertilizer supply in real time according to the crop's growth stage and water and fertilizer requirements, ensuring that each plant receives adequate water and nutrients, reducing unnecessary water evaporation and fertilizer loss, improving the efficiency of water and fertilizer use, creating favorable growing conditions for crops, enhancing their resistance to adverse conditions, and thus increasing yield and improving quality. The automated control system reduces manual intervention, lowers labor intensity, and facilitates large-scale production, taking into account the different root depths and water and fertilizer absorption characteristics of wheat and corn. The device should have independent water and fertilizer supply channels to meet their respective needs. It should integrate a sensor network to monitor soil moisture, temperature, and crop growth status, combine meteorological data to predict future trends, and automatically adjust irrigation and fertilization plans. It should select low-energy pump stations, filters, and pipe materials to reduce operating costs and optimize the dripper structure design to avoid clogging. The wheat-corn intercropping water and fertilizer separate control drip irrigation device is an important manifestation of the progress of modern agricultural technology. It not only helps to solve the current resource shortage problem faced by agricultural production, but also effectively promotes the development of green and sustainable agriculture, although it still faces some technical and economic challenges.
[0025] Please see Figures 1-5This utility model provides an embodiment of a wheat-corn intercropping water and fertilizer controlled drip irrigation device, including a drip irrigation pipe 1; and sealing cover plates 2 respectively installed at both ends of the drip irrigation pipe 1. The sealing cover plates 2 are used to seal both ends of the drip irrigation pipe 1. Two mounting blocks 3 are connected to the outer side of the sealing cover plates 2. Insert rods 4 are installed at the lower end of the mounting blocks 3. The controlled component includes a fixing rod 6, a separating module, a distribution module, a cavity module, a connecting module, a transport module, and a drip irrigation module disposed inside the drip irrigation pipe 1. The separating module is used to separate the internal cavity of the drip irrigation pipe 1. The distribution module is responsible for guiding water into the corresponding internal cavity of the drip irrigation pipe 1. The cavity module serves as a buffer cavity area for the distribution module. The connecting module is used to install the transport module. The transport module is responsible for transporting external drip irrigation water into the drip irrigation pipe 1. The drip irrigation module is used for drip irrigation. The insert rods 4 are used to fix the entire drip irrigation pipe 1 to the ground. Pipe 1 is used to transport and distribute the water-fertilizer mixture. Sealing caps 2 are installed at both ends to seal the pipe and prevent leakage. Mounting blocks 3 are located on the outside of the sealing caps 2 for connecting insert rods 4. Insert rods 4 can be used to fix the entire drip irrigation pipe 1 in the field, ensuring stability. A fixing rod 6 is installed inside the drip irrigation pipe 1 to support the internal structure. A partition module divides the inside of the drip irrigation pipe 1 into four independent chambers for zoned control. A distribution module is responsible for guiding the water flow into the corresponding chambers, facilitating precise control according to the needs of different crops. The partition module acts as a water flow buffer, making the water pressure more stable. A connecting module is connected to the partition module for installing the transport module. The drip irrigation module consists of four rows of drip irrigation holes 5 with different spacing and diameters, corresponding to the four chambers. It can precisely control the water outlet position and flow rate based on the planting density and root distribution of wheat and corn, meeting the differentiated irrigation needs of intercropping.
[0026] Please see Figures 1-5 In this embodiment, the partition module includes a partition 7 installed on the outer side of the fixed rod 6. The partition 7 divides the interior of the drip irrigation pipe 1 into four spaces (the partition 7 divides the interior space of the drip irrigation pipe 1 into four independent chambers, realizing independent water and fertilizer delivery and control in different areas, which is convenient for zoned management according to the different needs of wheat and corn). The distribution module includes valves 8 installed on the surface of the left sealing cover plate 2. There are four valves 8, which are respectively connected to the four cavities inside the drip irrigation pipe 1 (the valves 8 realize independent opening and closing and flow regulation of each chamber. According to the crop type and growth stage, one or more valves 8 can be selectively opened to achieve the purpose of precise irrigation and fertilization). The cavity module includes a connecting cover 9 installed on the surface of the left sealing cover plate 2. The connecting cover 9 forms a cavity between the sealing cover plates 2. The cavity of the connecting cover 9 is used to connect the four paths of the valves 8 (the connecting cover 9 serves as a water flow buffer and confluence channel between the four valves 8, balancing the water flow pressure, making the water flow into each valve 8 more uniform and stable, and improving the stability and reliability of the device operation).
[0027] Please see Figures 1-5 In this embodiment, the connection module includes a connector 10 disposed on the left end face of the connecting cover 9. The connector 10 is interconnected with the cavity of the connecting cover 9 (the connector 10 is connected to the cavity inside the connecting cover 9, serving as a transition interface for external water sources to enter the drip irrigation device, providing structural support and a sealed connection to ensure that water flow is smoothly introduced into the drip irrigation device from the external transport module). The transport module includes a flexible hose 11 installed inside the connector 10. The flexible hose 11 is responsible for transporting external drip irrigation water into the drip irrigation pipe 1 (the flexible hose 11 delivers external irrigation water or water-fertilizer mixture to the cavity of the connecting cover 9 through the connector 10, and has good flexibility to adapt to different...). The drip irrigation module includes drip irrigation holes 5 on the surface of the drip irrigation pipe 1, arranged in four rows. The rows of drip irrigation holes 5 maintain different spacing and different diameters. The four rows of drip irrigation holes 5 correspond to different cavities in the drip irrigation pipe 1 (the drip irrigation holes 5 realize precise drip irrigation to the root area of the crop. The four rows of drip irrigation holes 5 correspond to four independent cavities in the drip irrigation pipe 1, which can differentiate the water output and coverage according to the planting density, row spacing and root distribution of wheat and corn, improve irrigation efficiency, reduce water waste and enhance water saving effect).
[0028] During operation, the drip irrigation pipe 1 delivers the water-fertilizer mixture. Both ends are sealed with sealing caps 2 to prevent leakage. An installation block 3 is located on the outside of the sealing cap 2, with a connecting rod 4 at the lower end. The connecting rod 4 secures the entire drip irrigation system in the field, ensuring stability. Inside the drip irrigation pipe 1, a fixing rod 6 supports the internal components. A partition 7 is installed on the outside of the fixing rod 6, dividing the inside of the drip irrigation pipe 1 into four independent chambers, allowing for independent control of different areas. The distribution module consists of four valves 8, installed on the surface of the left sealing cap 2. Each valve 8 corresponds to an independent chamber. By adjusting the valves 8, a specific path can be selectively opened or closed, thereby controlling the water supply to different crop areas. The diaphragm module consists of a connecting cover 9, which forms a buffer diaphragm between the connecting cover 9 and the sealing cover 2. This buffer diaphragm is used to connect the water flow paths of the four valves 8, and plays a role in stabilizing pressure, buffering, and uniformly distributing the flow, thus preventing pressure instability caused by water flow impact. The connecting module includes a connector 10, which is connected to the diaphragm of the connecting cover 9. The hose 11 in the transport module is installed inside the connector 10 and is responsible for introducing the external water and fertilizer solution into the drip irrigation pipe 1. The drip irrigation module consists of four rows of drip irrigation holes 5, which correspond to the four independent chambers in the drip irrigation pipe 1. Each row of drip irrigation holes 5 has a different spacing and aperture design, which can accurately control the water outlet position and flow rate according to the planting density, row spacing configuration, and root distribution characteristics of wheat and corn, so as to achieve differentiated irrigation.
[0029] Through the above steps, by setting a partition 7 and four sets of independent valves 8 inside the drip irrigation pipe 1, the drip irrigation pipe 1 is divided into four independent chambers, and four rows of drip irrigation holes 5 with different spacing and diameters are arranged on the surface of the drip irrigation pipe 1. According to the intercropping row spacing, planting density and root distribution characteristics of wheat and corn, the corresponding chamber and drip irrigation hole 5 can be selectively activated to achieve precise water and fertilizer matching, adapt to the irrigation needs of various intercropping patterns, and solve the problem that common wheat and corn intercropping strip drip irrigation devices cannot adjust the drip irrigation position according to the planting density and root distribution characteristics.
