Description

Technical Field

[0001] This invention relates to the field of three-dimensional cultivation technology, specifically to a three-dimensional cultivation and fertilization device applicable to thin-shelled pecans and medicinal plants. Background Technology

[0002] Pecan is a tall tree belonging to the Juglandaceae family, valued for its fruit, oil, timber, and ornamental qualities. Its intercropping with medicinal plants in a three-dimensional cultivation model is an ecologically efficient planting approach. This model achieves efficient resource utilization through spatial stratification (the upper layer of pecans provides shade, while the lower layer of medicinal plants utilizes diffused light) and staggered planting times. Pecans are planted at a spacing of 4m×5m to 7m×8m. Intercropping pecans with other plants such as 'Fengdan' (a type of pecan), 'Boju' (a type of chrysanthemum), and black peanuts achieves a win-win situation for both ecological and economic benefits through three-dimensional cultivation. 'Boju' is a medicinal chrysanthemum variety with strong adaptability and can be intercropped with pecans.

[0003] The height for setting the trunk varies depending on the cultivation purpose: For orchards, the ideal height for setting the trunk is 1.5-1.8 meters to promote canopy formation and fruit production.

[0004] During the planting process, newly planted pecans have unstable roots and shallow root systems. After planting, workers often directly water the roots of the pecans with large amounts of water pipes, which may cause the roots to become unstable and the trees to tip over in severe weather such as strong winds and rain, seriously affecting the survival of the pecan trees. In addition, the irrigation points are often exposed to the outside, and the water evaporates quickly, resulting in a waste of water resources.

[0005] When cultivating thin-shelled pecans and medicinal chrysanthemums in a three-dimensional system, the chrysanthemums require appropriate water control during their growing season. The relative soil moisture content should be maintained at 70%–80%. For every 1°C increase in temperature, the evaporation from the water surface increases by approximately 2%–3%. Increased solar radiation directly accelerates water evaporation, and for every 10% decrease in relative humidity, evaporation can increase by 10%–15%. When the wind speed exceeds 3 m / s, evaporation increases exponentially with wind speed. Therefore, how to improve the utilization rate of water resources through frequent watering is an urgent problem to be solved. Summary of the Invention

[0006] The technical solution adopted by this invention to solve its technical problem is: a three-dimensional cultivation and fertilization device suitable for thin-shelled pecans and medicinal plants, which can achieve irrigation volume control accuracy of ±2.5%, increase fertilizer utilization rate by 40%, save water by 35% compared with the traditional method, and at the same time reduce the volatilization of water and fertilizer when spraying on the roots of thin-shelled pecans, thereby improving the utilization rate of water and fertilizer.

The three-dimensional support frame includes a connecting pipe for support connection, and the connecting pipe is fixedly connected to the arc-shaped cultivation rack.

[0014] Guide grooves are provided on both sides of the connecting pipe, and a fan-shaped nozzle is slidably installed on the outer wall of the connecting pipe. The spray angle of the fan-shaped nozzle is 30°-180°.

[0015] Preferably, a support box is provided through the middle of the connecting pipe, and an electrically controlled push rod for adjusting the position of the support box is fixedly connected to the bottom;

[0016] Mounting brackets are fixedly connected to both sides of the supporting horizontal box. A rotating shaft for driving the fan-shaped nozzle to rotate is rotatably set in the middle of the mounting bracket. A micro motor is fixedly connected to the side wall of the mounting bracket, and the output end of the micro motor is fixedly connected to the rotating shaft.

[0017] Preferably, a micro pump is fixedly installed at the bottom of the inner wall of the connecting pipe, and the micro pump is connected to the branch pipes placed on both sides of the arc-shaped cultivation rack through the water pipe.

[0023] The beneficial effects of this invention are:

[0024] (1) The composite three-dimensional cultivation and fertilization device for thin-shelled pecans and medicinal plants described in this invention has the advantage of supporting the outer wall of the thin-shelled pecan with an elastic plate, preventing it from tipping over, compared to the prior art. The elastic plate is made of elastic material, and when the tilt angle of the thin-shelled pecan is too large, the elastic plate will deform to make way until the thin-shelled pecan comes into contact with the multi-layer ring cultivation structure at the top. The multi-layer ring cultivation structure supports the thin-shelled pecan, preventing it from falling over completely and its roots from being pulled out of the soil during the falling process, which would cause the thin-shelled pecan to die. At the same time, the elastic plate's movement can prevent hard contact with the thin-shelled pecan, which would damage the pecan trunk. The elastic plate can cover the roots of the thin-shelled pecan, which can reduce the soil around the roots from being exposed to the air and reduce water evaporation.

[0025] (2) The composite three-dimensional cultivation and fertilization device for thin-shelled pecans and medicinal plants described in this invention can spray water and fertilizer onto thin-shelled pecans by controlling the operation of the pressure nozzle. During the spraying process, the humidity of the surrounding area is monitored by the humidity sensor integrated in the connecting pipe, and various data of the soil are monitored by the soil multi-parameter sensor. When the humidity is lower than the preset range, the pressure nozzle will open to ensure that the thin-shelled pecans are within the preset humidity range, which is beneficial to the growth of thin-shelled pecans.

[0026] (3) The fertilization device for composite three-dimensional cultivation of thin-shelled pecans and medicinal plants described in this invention achieves irrigation volume control accuracy of ±2.5% through PLC control system, increases fertilizer utilization rate by 40%, saves water by 35% compared with traditional methods, and meets the three-dimensional precision water and fertilizer management needs of composite cultivation system.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1-7 As shown, the present invention provides a composite three-dimensional cultivation and fertilization device for thin-shelled pecans and medicinal plants, comprising a multi-layered ring cultivation structure 300.

[0038] The multi-layer ring cultivation structure 300 includes an arc-shaped cultivation rack 301 for composite three-dimensional cultivation of medicinal plants; the upper surface of the arc-shaped cultivation rack 301 is provided with a partition groove 303, and the bottom of the arc-shaped cultivation rack 301 is provided with a stainless steel pipe 320 for liquid fertilizer to flow out.

[0039] Multiple arc-shaped cultivation racks 301 are connected to form a ring, and the inner wall of the arc-shaped cultivation racks 301 is connected to an elastic plate 460 for limiting the position of thin-shelled pecan seedlings.

[0040] refer to Figure 1 , Figure 3 and Figure 6 As shown, a slide rail 462 is fixedly connected to the inner wall of the arc-shaped cultivation rack 301, and an elastic plate 460 is slidably connected to the upper surface of the slide rail 462.

[0041] The elastic plate is tilted at an angle between 45° and 60°.

[0042] The multi-layer ring cultivation structure 300 can be assembled into two or more layers depending on the specific usage environment. Adjacent layers are connected by a three-dimensional support frame 400. Each layer of the multi-layer ring cultivation structure 300 can be planted with medicinal plants, increasing space utilization. The multi-layer ring cultivation structure 300 enables the composite planting of thin-shelled pecans and medicinal plants. The zoned fertilization unit precisely controls the fertilizer supply to plants at different levels, improving resource utilization while reducing human intervention.

[0043] The elastic board 460 supports the outer wall of the thin-shelled pecan tree, preventing it from tipping over. The elastic board 460's tilt angle is between 45° and 60°, providing better support when the pecan tree tilts. Being an elastic material, the board 460 deforms to allow the pecan tree to adjust its position when the tilt angle is too large, until it contacts the multi-layered ring-shaped cultivation structure 300 at the top. This structure supports the pecan tree, preventing it from falling completely and its roots from being pulled out of the soil, causing death. The adjustment of the elastic board 460 also prevents hard contact with the pecan tree, avoiding damage to the trunk. The elastic board 460 also covers the entire root area, reducing soil exposure and water evaporation.

[0044] During the seedling stage, keep the soil moist but not waterlogged by spraying appropriate water and fertilizer; during the growing season, control watering appropriately, keeping the relative soil moisture content between 70% and 80%; strictly control watering during the flower bud differentiation period of Bo chrysanthemum, and do not water if the leaves do not wilt.

[0045] refer to Figure 3 and Figure 6 As shown, the inner and outer walls of the arc-shaped cultivation rack 301 are fitted with branch pipes 103. The branch pipes 103 placed on the inner wall of the arc-shaped cultivation rack 301 are flexible hoses, and the bottom of the hose is connected to a pressure nozzle 463 at a staggered position with the slide rail 462.

[0046] Multiple sets of branch pipes 103 are connected to a three-dimensional pipe 102 set on one side of the main fertilization pipe 100. Water and fertilizer are transported to the three-dimensional pipe 102 through the main fertilization pipe 100, and water and fertilizer are transported to the branch pipes 103 through the three-dimensional pipe 102. Water and fertilizer are supplied to the branch pipes 103 through the main fertilization pipe 100.

[0047] When spraying is required, water and fertilizer can be sprayed onto the thin-shelled pecans by controlling the operation of the pressure nozzle 463. During the spraying process, the humidity sensor integrated in the connecting pipe 401 monitors the surrounding humidity over time, and the soil multi-parameter sensor monitors various soil data. When the humidity is lower than the preset range, the pressure nozzle 463 will open to ensure that the thin-shelled pecans are within the preset humidity range, which is beneficial to the growth of the thin-shelled pecans.

[0048] refer to Figures 2-5 As shown, a three-dimensional support frame 400 is connected to a partition groove 303 in the middle of the upper surface of the arc-shaped cultivation rack 301. The three-dimensional support frame 400 includes a connecting pipe 401 for support connection, and the connecting pipe 401 is fixedly connected to the arc-shaped cultivation rack 301.

[0049] Guide grooves are provided on both sides of the connecting pipe 401, and a fan-shaped nozzle 402 is slidably provided on the outer wall of the connecting pipe 401. The spraying angle range of the fan-shaped nozzle 402 is 30°-180°.

[0050] A support box 406 is provided through the middle of the connecting pipe 401, and an electrically controlled push rod 408 for adjusting the position of the support box 406 is fixedly connected to the bottom.

[0051] Mounting brackets 403 are fixedly connected to both sides of the supporting horizontal box 406. A rotating shaft for driving the fan-shaped nozzle 402 to rotate is rotatably set in the middle of the mounting bracket 403. A micro motor 404 is fixedly connected to the side wall of the mounting bracket 403. The output end of the micro motor 404 is fixedly connected to the rotating shaft.

[0052] Based on the growth of the Bozhou chrysanthemum, the position of the fan-shaped nozzle 402 can be adjusted according to the height of the chrysanthemum. The height of the supporting horizontal box 406 can be adjusted by the setting of the electric control push rod 408. The detection camera for detecting plant growth works in conjunction with the electric control push rod 408. The detection camera for detecting plant growth transmits the growth of the Bozhou chrysanthemum in real time, and controls the electric control push rod 408 through the PLC intelligent control module, thereby achieving precise adjustment of the height of the fan-shaped nozzle 402. The adjustment of the fan-shaped nozzle 402 adapts to the root distribution of plants at different heights, avoids fertilizer waste, and improves the uniformity of fertilization.

[0053] The micro motor 404 drives the rotating shaft to rotate during the operation of the fan-shaped nozzle 402, thereby rotating the fan-shaped nozzle 402. The spraying angle range of the fan-shaped nozzle 402 is 30°-180°, which can achieve the coverage of water and fertilizer spraying throughout the entire growth process of Bo chrysanthemum.

[0054] Chrysanthemums are planted in an arc-shaped cultivation rack 301 and sprayed with water and fertilizer through a fan-shaped nozzle 402. Water and fertilizer are continuously supplied through the branch pipe 103. The water and fertilizer are pumped into the support box 406 and then sprayed through the connecting bend pipe 407 into the fan-shaped nozzle 402.

[0055] Each of the arc-shaped cultivation racks 301 has a plug-in sleeve 302 at the bottom. The connecting pipe 401 of the lower layer can be inserted into the plug-in sleeve 302 at the bottom of the corresponding upper arc-shaped cultivation rack 301. The whole assembly process is convenient and quick. Multiple arc-shaped cultivation racks 301 are connected by elastic connectors 306 to ensure the stability of the connection. At the same time, the elastic connectors 306 are connected to multiple arc-shaped cultivation racks 301 by stainless steel bolts, making disassembly and assembly convenient and quick.

[0056] refer to Figure 5 As shown, a micro pump 410 is fixedly installed at the bottom of the inner wall of the connecting pipe 401. The micro pump 410 is connected to the branch pipes 103 on both sides of the arc-shaped cultivation rack 301 through a water pipe. The micro pump 410 is connected to the support box 406 through a threaded pipe 409. The support box 406 is connected to the fan-shaped nozzle 402 above through a connecting bend pipe 407.

[0057] The micro pump 410 pumps water and fertilizer from branch pipe 103 into threaded pipe 409. Threaded pipe 409 is extended as the position of fan-shaped nozzle 402 is adjusted, allowing water and fertilizer to enter the support box 406. From there, it flows through connecting bend 407 into the fan-shaped nozzle 402 for spraying. A pressure nozzle 463 is installed at the bottom of branch pipe 103, located inside the arc-shaped cultivation rack 301, allowing direct spraying of water and fertilizer to the roots of the thin-shelled pecan. The micro pump 410 is a variable frequency centrifugal pump.

[0058] When the elastic plate 460 is compressed, the elastic plate 460 first moves along the slide 462 to make room, and then the branch pipe 103 placed inside the arc-shaped cultivation rack 301 is compressed by the elastic plate 460 to replenish water to the roots of the thin-shelled pecan, so as to prevent the roots from leaking out of the soil during the tilting process of the thin-shelled pecan and causing water shortage, which would affect the growth of the thin-shelled pecan.

[0059] refer to Figure 5 As shown, a removable filter screen 304 is provided at the bottom of the partitioned trough 303 for medicinal plants. A guide channel 305 is connected below the filter screen 304, and the bottom of the guide channel 305 is connected to a stainless steel pipe 320.

[0060] Water and fertilizer are sprayed onto the medicinal plants through the fan-shaped nozzle 402. If too much water and fertilizer is sprayed, it will enter the stainless steel pipe 320 through the guide channel 305. The water and fertilizer will drip down the stainless steel pipe 320 onto the next layer of medicinal plants. The bottom layer of stainless steel pipe 320 is inserted into the ground to ensure the overall stability of the three-dimensional cultivation and fertilization device. At the same time, it can also allow water and fertilizer to directly enter the soil at a certain depth, reducing water and fertilizer evaporation and increasing the utilization rate of water and fertilizer.

[0061] refer to Figure 7As shown, a humidity sensor and a pH sensor are integrated within the connecting pipe 401, and the sensor data is transmitted to the PLC control system via a wireless module. The fertilization device includes a sensing module, which comprises a liquid level sensor and a pressure sensor for liquid level sensing.

[0062] The sensing module includes a detection camera for detecting plant growth and for transmitting images of the plant.

[0063] The soil multi-parameter sensor can monitor soil moisture / EC / pH in real time, and the pipeline pressure sensor...

[0064] It can monitor pipeline pressure to ensure a stable supply of water and fertilizer to branch pipeline 103;

[0065] Real-time monitoring of soil environmental parameters and automatic adjustment of fertilization strategies enable intelligent and precise fertilization, with the three-dimensional cultivation rack and zoned fertilization units as the core, covering the entire structure of the device.

[0066] The PLC control system achieves irrigation volume control accuracy of ±2.5%, increases fertilizer utilization by 40%, and saves 35% of water compared to traditional methods, meeting the needs of three-dimensional precision water and fertilizer management in the composite cultivation system.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
