Description

Technical Field

[0001] This invention relates to the field of wheat stress-resistant cultivation technology, and more particularly to a wheat stress-resistant cultivation device and method. Background Technology

[0002] Wheat is a general term for plants of the wheat family. It is a monocotyledonous plant and a type of grass that is widely cultivated around the world. Plant resistance refers to certain traits that a plant possesses to resist adverse environments, such as resistance to cold, drought, salt, and pests and diseases. Excellent resistance traits that appear in one plant in nature are difficult to transfer to other plant species under natural conditions, mainly because there is reproductive isolation between different plant species.

[0003] Application number 201811288962.6 discloses a wheat stress-resistant cultivation device and method, including the following steps: preparation of device manufacturing materials, processing of device parts, assembly of cultivation device, wheat seed coating and sowing, seedling fertilization, spraying and irrigation, and wheat stress resistance testing. This invention can reduce the land required for wheat cultivation, save space utilization, inhibit pathogen infection, reduce disease occurrence, improve wheat disease resistance, and thus increase yield. It also allows for orderly planting of wheat with uniform spacing between seedlings. However, this invention requires manual pollination of wheat seedlings during use, which is time-consuming and labor-intensive.

[0004] In existing wheat stress-resistant cultivation devices, when spraying nutrient solution and water, a water-passing net is usually placed under the wheat cultivation box to prevent root rot. This net allows excess water to drain into the cavity below. However, as the water and nutrient solution fall into the cavity, they carry away a small amount of fine soil particles, resulting in the loss of soil, nutrient solution, and water. After this loss, the cultivation box needs to be re-sprayed with water and nutrient solution, increasing costs and reducing resource utilization.

[0005] Meanwhile, during the wheat growth and heading process, the device used in the laboratory requires manual pollination of wheat, which is time-consuming and labor-intensive. When spraying water and nutrient solution onto wheat through nozzles, if the wheat density is high, the nutrient solution and water are not easily sprayed directly into the soil where the wheat seedlings are growing, which can easily lead to waste of nutrient solution. At the same time, when the cutter cuts the soil, if the soil is severely compacted or there are stones in the soil, the fixed-angle cutter is not conducive to cutting the compacted soil or turning over the stones in the soil. Summary of the Invention

[0021] A method for using a wheat stress-resistant cultivation device, the method comprising the following steps:

[0022] Step 1: Plant the wheat neatly in the cultivation box, and regularly spray it with nutrient solution and water with the help of the spraying device, so that the water and nutrient solution fall accurately into the soil below the spraying device to complete the spraying of nutrient solution and water.

[0023] Step 2: During the wheat growth process, with the help of the return component, the water, soil and nutrient solution collected in the collection box are transported back to the soil at the top of the net for reuse.

[0024] Step 3: During the operation of the reflux component, the soil collected in the collection box is crushed with the assistance of the surrounding crushing component, which improves the soil crushing effect and ensures that the soil can be smoothly transported to the branch pipe to complete the soil reflux transportation.

[0025] Step 4: During the wheat heading process, the combination of the reflux component and the spraying component allows the reflux component to open up the leaves of the wheat seedlings so that the water and nutrient solution sprayed by the spraying component can directly act on the soil at the roots of the wheat seedlings, reducing the waste of water and nutrient solution.

[0026] Step 5: During the wheat flowering process, the height of the elastic rope in the reflux component is controlled by the electromagnet in the spraying component through the cooperation of the reflux component and the spraying component, so that the elastic rope can accurately pollinate the wheat ears.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention, by setting up a reflux component, collects water, nutrient solution, and soil falling from the net through a collection frame. Then, with the assistance of a first water pump in the reflux component, the water, nutrient solution, and soil in the collection frame are extracted and re-sprayed onto the soil at the top of the net. Furthermore, with the assistance of scrapers and scoring blades in the reflux component, the soil adhering to the bottom of the collection frame is shoveled up and transported to the surrounding crushing component for crushing, thereby ensuring the stability of the reflux component in use.

[0029] 2. This invention, by setting up a surrounding crushing component, uses scrapers and scoring blades to push the soil in the collection box to the surrounding crushing component. The two pointed rods in the surrounding crushing component approach each other, and the drive motor drives the crushing and mixing rod to rotate, so that the bumps in the soil can be crushed. This also allows the soil to be fully mixed with water and nutrient solution, so that the return component can smoothly extract it. This improves the recycling and reuse of water and nutrient solution and reduces the waste of nutrient solution.

[0030] 3. This invention, by setting up a spraying component, and with the assistance of a second cylinder and a second water pump in the spraying component, enables the spraying component to reciprocate at the top of the cultivation box. At the same time, under the action of the second water pump, the spraying component can draw water and nutrient solution from the water tank and spray it onto the soil at the top of the net for wheat cultivation. During the spraying process, the spraying component, with the assistance of a dispersing rod, makes the spraying of water and nutrient solution more uniform, thereby improving the spraying effect of the equipment.

[0031] 4. This invention, by incorporating pressure sensors, resistance sensors, electromagnets, elastic ropes, and cutters, enables the equipment to loosen compacted soil when spraying water and nutrient solution onto wheat seedlings. Furthermore, during wheat growth, the sprayed water and nutrient solution directly reach the soil around the seedling roots, reducing waste caused by water and nutrient solution adhering to the leaves. It also allows for pollination after the wheat heading stage. Moreover, when dealing with seedlings of varying growth rates, the height of the elastic rope can be adjusted for pollination, making the equipment more precise and improving its effectiveness in cultivating wheat.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Example 1

[0043] The wheat stress-resistant cultivation device disclosed in this invention is mainly applied to existing wheat stress-resistant cultivation devices. During the use of wheat nutrient solution and water spraying, in order to prevent root rot at the bottom of the wheat, a water-passing net is usually placed under the wheat cultivation box to ensure that excess water can be drained into the cavity below through the water-passing net. However, in the process of water and nutrient solution falling into the cavity below, a small amount of fine soil will be carried away, which will cause the loss of soil, nutrient solution and water. After this part of the water and nutrient solution is lost, the cultivation box needs to be re-sprayed with water and nutrient solution, resulting in increased costs and reduced resource utilization.

[0044] Reference Figures 1-8 A stress-resistant cultivation device for wheat includes a cultivation box 1 and a collection frame 4. A net 15 is provided at the bottom of the cultivation box 1, and a first guide rail 5 is provided on one side of the collection frame 4. A sliding block 16 is slidably connected inside the first guide rail 5. A reflux assembly 17 is provided on the side of the sliding block 16 facing the inside of the collection frame 4. The reflux assembly 17 includes an L-shaped movable long pipe 1701 and a mounting plate 1703. The mounting plate 1703 is located outside the sliding block 16, with the top side of the mounting plate 1703... An adjusting block 1704 is provided, with a mounting hole at its top. An L-shaped movable tube 1701 is positioned inside the mounting hole. An elongated hole is formed on the outer side of the net 15, with the adjusting block 1704 located inside the elongated hole. A sealing elastic band 1713 is provided on both sides of the adjusting block 1704, with the other end of the sealing elastic band 1713 positioned inside the net 15 at the elongated hole. The L-shaped movable tube 1701 has connecting holes spaced evenly on its upward-facing outer side, and each connecting hole contains a... A branch pipe 1702 is provided, and an external patch 1709 is provided on the outer side of the open end of each branch pipe 1702. An anti-blocking screw is provided on the outer side of the external patch 1709. An anti-blocking thin rod 1710 is located inside the open end of the branch pipe 1702. A spring 1712 is provided on the outer side of each branch pipe 1702. A cutter 1711 is provided on the other end of the spring 1712. A pump ring frame 1706 is provided on the other side of the mounting plate 1703, and a first water pump 1705 is provided inside the pump ring frame 1706. The first water pump 1705 has a first water inlet pipe 1707 at its inlet end, and the other end of the first water inlet pipe 1707 is located inside the collection frame 4. The first water pump 1705 has a first water delivery pipe 1708 at its delivery end, and the other end of the first water delivery pipe 1708 is inserted into the interior of the L-shaped moving long pipe 1701. The end of the first guide rail 5 has an end block 2, and the side of the end block 2 facing the sliding block 16 has a first cylinder 3. The output end of the first cylinder 3 is located on the outside of the sliding block 16.

[0045] In specific application scenarios, during the cultivation of wheat to enhance its resistance, some nutrient solution, water, and soil pass through the net 15 and fall into the collection box 4 below. By staggering the spraying times of nutrient solution and water, when the humidity sensor 28 detects that the soil humidity is low, the first cylinder 3 drives the L-shaped moving pipe 1701 to move. During the movement, the first water pump 1705 is activated. The first water pump 1705 guides the nutrient solution, soil, and water in the collection box 4 into each branch pipe 1702, and then discharges them into the soil inside the cultivation box 1 through the branch pipes 1702. This achieves the recycling of water, soil, and nutrient solution, improves resource utilization, and optimizes the wheat's growth environment.

[0046] It should be noted that during the movement of the L-shaped mobile long pipe 1701, the cutter 1711 cuts the soil to reduce the resistance of the branch pipe 1702. At the same time, the anti-clogging thin rod 1710 at the opening end of the branch pipe 1702 prevents the soil from tightly blocking the opening end of the branch pipe 1702, ensuring that water, nutrient solution and fine soil can be discharged through the branch pipe 1702.

[0047] Specifically, when the L-shaped moving long pipe 1701 moves, the sealing elastic band 1713 seals the long hole of the net 15 to prevent soil above the net 15 from falling in batches through the long hole into the collection box 4 below, thus preventing soil loss.

[0048] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, an extension rod 18 is provided on one side of the mounting plate 1703 near the bottom, and a scraper 22 is provided on the other end of the extension rod 18. The scraper 22 is in contact with the bottom inner wall of the collection frame 4. Shaft blocks 21 are provided on both ends of the scraper 22 facing the first water pump 1705. The opposite sides of the two shaft blocks 21 are connected to the same connecting shaft 20 through bearings. Scoring blades 19 are provided at equal intervals on the outer side of the connecting shaft 20.

[0049] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6In a preferred embodiment, a support frame 6 is provided on both sides of the collection frame 4, and the cultivation box 1 is located on the opposite side of the two support frames 6. A crushing and pulverizing component 23 is provided inside the collection frame 4 near one of the support frames 6. The crushing and pulverizing component 23 includes a middle fixing plate 2301, which is located on one inner wall of the collection frame 4. Side elastic enclosures 2304 are provided on both sides of the middle fixing plate 2301. A first hydraulic cylinder 2305 is provided on both sides of the collection frame 4. The output ends of the two first hydraulic cylinders 2305 are located on the outer side of the corresponding side elastic enclosures 2304. Pointed rods 2306 are provided at equal intervals on the opposite side of the two side elastic enclosures 2304. A motor frame 2302 is provided on the top of the middle fixing plate 2301. A drive motor 2303 is provided on the top of the motor frame 2302. A drive shaft 2308 is provided on the output shaft of the drive motor 2303 through a coupling. A crushing and stirring rod 2307 is provided on the outer side of the drive shaft 2308 near the bottom.

[0050] In specific application scenarios, during the operation of the reflux assembly 17, the first hydraulic cylinder 2305 is adjusted to drive the side elastic baffle 2304 to move towards the center line of the collection frame 4. The soil is crushed by the various pointed rods 2306. At the same time, the drive motor 2303 is started. The drive motor 2303 drives the crushing and stirring rod 2307 to cooperate with the pointed rods 2306 to improve the soil crushing effect and ensure that the soil can be smoothly transported to the branch pipe 1702, preventing soil blockage inside the branch pipe 1702 and ensuring that the branch pipe 1702 can be in working condition for a long time.

[0051] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 In a preferred embodiment, the cultivation box 1 is provided with second guide rails 12 on both sides near the top, and the two second guide rails 12 are slidably connected to the same sliding rod frame 27. Two upright plates 25 are provided on one inner wall of the cultivation box 1, and a second cylinder 26 is provided on the side of the two upright plates 25 facing the sliding rod frame 27. The output ends of the two second cylinders 26 are located on the outside of the sliding rod frame 27.

[0052] In this invention, a fixing frame 24 is provided on the outer side of the sliding rod frame 27, and a spraying assembly 13 is provided at the fixing frame 24. The spraying assembly 13 includes a spraying connecting pipe 1301, which is located on the outer side of the fixing frame 24. Spray holes are evenly spaced on the downward-facing outer side of the spraying connecting pipe 1301, and a nozzle 1303 is provided inside each spray hole. A fixing rod 1308 is provided near the top of each nozzle 1303 on the spraying connecting pipe 1301, and a fixing rod 1308 is provided at the bottom of each fixing rod 1308.

The air supply end of the air compressor 1305 is connected to the interior of the hollow air blower plate 1304 through a pipe. A central connecting rod 1307 is provided on the outer side of the hollow air blower plate 1304 away from the air compressor 1305. Dispersing rods 1302 are distributed in a ring around the outer side of the central connecting rod 1307.

[0053] Specifically, during the spraying of nutrient solution and water, the second cylinder 26 is adjusted to move the sliding rod 27 in the second guide rail 12, and the second water pump 11 is started. The second water pump 11 delivers water and nutrient solution to the spraying connecting pipe 1301, which is then sprayed out through each nozzle 1303. During the spraying process, the air compressor 1305 is started. The air compressor 1305 blows out compressed gas through the air holes 1306 on the hollow air blower plate 1304. This compressed gas compresses the water and nutrient solution to prevent them from deviating. At the same time, the water and nutrient solution pass through each dispersing rod 1302, which disperses the water and nutrient solution to ensure the uniformity of the spraying and improve the spraying effect.

A humidity sensor 28 is provided on the inner wall of the cultivation box 1 on the side away from the water tank 10.

[0055] Example 2

[0056] Based on the above-described embodiment 1, a wheat stress-resistant cultivation device is available. Although the device can irrigate wheat with water and nutrient solution during use, in practice, during the wheat growth and heading process, the device used in the laboratory requires manual pollination, which is time-consuming and labor-intensive. Furthermore, when spraying water and nutrient solution through nozzle 1303, if the wheat density is high, the nutrient solution and water are not easily sprayed directly into the soil where the wheat seedlings are growing, easily leading to waste of nutrient solution. Additionally, when the cutter 1711 cuts the soil, if the soil is severely compacted or contains stones, the fixed-angle cutter 1711 is not conducive to cutting the compacted soil or turning over the stones. Therefore, we propose the following technical solution:

[0057] Reference Figures 1 to 8 A branch pipe 1702 is mounted on an L-shaped movable tube 1701 via a torsion spring. A magnetic cutter 1711 is rotatably mounted on the branch pipe 1702. A spring 1712 is positioned between the cutter 1711 and the branch pipe 1702. An elastic rope 1714 is installed between every two branch pipes 1702 near the L-shaped movable tube 1701. A pressure sensor is also installed at the lower end of the L-shaped movable tube 1701. An electrically controlled telescopic rod is mounted on a mounting plate 1703, with its output end located at the lower end of the L-shaped movable tube 1701. A resistance sensor is installed on the cutter 1711. With the assistance of the electrically controlled telescopic rod, the L-shaped moving tube 1701 can be raised and lowered on the adjusting block 1704 and the first water supply pipe 1708, thereby adjusting the height of the L-shaped moving tube 1701. When the electromagnet is energized, it can attract the magnetic cutter 1711. Since one end of the cutter 1711 is hinged to the branch pipe 1702, the cutter 1711 can be angularly offset under the action of magnetic repulsion. At the same time, under the action of magnetic repulsion and torsion spring, the branch pipe 1702 will also be angularly adjusted.

[0058] An electromagnet is installed at the lower end of the spray connecting pipe 1301. The position of the electromagnet corresponds one-to-one with the position of the branch pipe 1702. Each electromagnet corresponds to the position of one branch pipe 1702, making the angle adjustment of the branch pipe 1702 and the adjustment of the cutter 1711 more precise.

[0059] During the use of this device, immediately after the wheat seeds are planted, the soil at the top of the net 15 is often loose. This loose soil easily passes through the net 15 and falls into the collection frame 4. After the wheat planting is completed, the second cylinder 26 is activated. With the assistance of the second cylinder 26, the spraying connecting pipe 1301 is moved back and forth. At the same time, the second water pump 11 is activated. With the assistance of the second water pump 11, the mixture of water and nutrient solution stored in the water tank 10 is transported through the second inlet pipe 9 and the second delivery pipe 14 to the spraying connecting pipe 1301. Then, the mixture is passed through the nozzle 1. Spraying is performed by nozzle 1303. The mixture sprayed from nozzle 1303 is further dispersed by the dispersion rod 1302, so that the mixture falls evenly into the soil at the top of the net 15. While providing water and nutrient solution to the wheat seeds, it also compacts the loose soil at the top of the net 15, which is conducive to full contact between the soil and the seeds, promoting seed germination and rooting, and promoting seed growth. During this process, if the humidity sensor 28 detects that the humidity in the cultivation box 1 is lower than the set threshold, the device will repeat the above process to replenish the soil at the top of the net 15 with water and nutrient solution.

[0060] As the wheat seeds grow, the seedlings emerge and press against the pressure sensor at the lower end of the L-shaped moving tube 1701. The pressure sensor detects the pressure value, and the equipment enters the wheat seedling stage. When the humidity sensor 28 detects that the humidity in the cultivation box 1 is lower than the set threshold, the second cylinder 26 is activated. With the assistance of the second cylinder 26, the spraying connecting pipe 1301 is moved back and forth. At the same time, the second water pump 11 is activated. With the assistance of the second water pump 11, the mixture of water and nutrient solution stored in the water tank 10 is transported to the spraying connecting pipe 1301 through the second water inlet pipe 9 and the second water delivery pipe 14. Then, the mixture is sprayed through the nozzle 1303. The mixture sprayed by the nozzle 1303 is further dispersed with the assistance of the dispersing rod 1302, so that the mixture falls evenly on the soil at the top of the net 15. At the same time, the first cylinder 3 and the first water pump 1701 are activated. 05. The output end of the first cylinder 3 drives the sliding block 16 to reciprocate, thereby causing the L-shaped moving long pipe 1701 to reciprocate. During the reciprocating movement of the L-shaped moving long pipe 1701, the mixture of soil, water and nutrient solution collected in the collection frame 4 is transported to the L-shaped moving long pipe 1701 through the first water inlet pipe 1707 and the first water delivery pipe 1708 with the assistance of the first water pump 1705. Then, the mixture of soil, water and nutrient solution in the L-shaped moving long pipe 1701 is sprayed onto the soil surface through the branch pipe 1702. The interaction between the spraying component 13 and the return component 17 replenishes the soil at the top of the net 15 with water and nutrient solution, and replenishes the lost soil back to the top of the net 15, providing the necessary conditions for the growth of wheat seedlings. It should be noted that the movement of the return component 17 and the spraying component 13 is synchronized.

[0061] As the L-shaped moving tube 1701 reciprocates, the cutter 1711 plows the soil it passes through. Because the soil has gradually compacted due to the earlier spraying of water and nutrient solution at the top of the net 15, this compacted soil is detrimental to root respiration and growth during the seedling stage. Therefore, the cutter 1711 plows the soil, allowing the soil at the top of the net 15 to be transported to both sides of the seedlings, which is beneficial for root respiration and promotes wheat seedling growth. However, during the plowing process, when the cutter 1711 encounters small stones or severely compacted soil, it experiences resistance, causing the cutter 1711 to... The resistance sensor readings gradually increase. When the readings exceed the threshold, the device controls the electromagnet on the spray pipe 1301 at the top of the cutter 1711 to be energized. After the electromagnet is energized, it generates a magnetic repulsion force on the cutter 1711. Under the action of the magnetic repulsion force, the cutter 1711 moves downward. As the L-shaped moving pipe 1701 moves, the cutter 1711 helps to loosen the compacted soil. Furthermore, the cutter 1711 forms a hook shape when it moves downward, which can throw out small stones in the soil and reduce the impact of stones on the root growth of seedlings.

[0062] As the L-shaped moving tube 1701 reciprocates, the scraper 22 and the scoring blade 19 also move accordingly. During this movement, the scraper 22 and the scoring blade 19 scoop up and push the soil settled at the bottom of the collection frame 4. When the settled soil is pushed to the position of the pointed rod 2306, the first hydraulic cylinder 2305 is activated. With the assistance of the first hydraulic cylinder 2305, the pointed rods 2306 at both ends are brought closer together, and the pointed rods 2306 at both ends break up the protrusions in the soil. At the same time, the drive motor 2303 is activated, causing the crushing and stirring rod 2307 to rotate. With the assistance of the crushing and stirring rod 2307, the protrusions are further broken up, so that the soil is fully mixed with the water and nutrient solution in the collection frame 4, which is conducive to being extracted by the first water supply pipe 1708, making the use of the return assembly 17 more stable.

[0063] As the wheat seedlings grow, their height will gradually increase. As the seedlings grow taller, the pressure sensor at the lower end of the L-shaped moving tube 1701 will gradually increase during its movement. When the pressure sensor reading exceeds a threshold, the device will activate the electrically controlled telescopic rod to move the L-shaped moving tube 1701 upwards, thus preventing damage to the wheat caused by the reciprocating movement of the L-shaped moving tube 1701.

[0064] When wheat enters the heading stage, its height will not increase significantly. At this time, as the L-shaped moving tube 1701 moves back and forth, the pressure sensor reading will stabilize. However, as wheat enters the heading stage, the seedlings' demand for water and nutrients increases. Due to the dense leaves at this time, a large portion of the water and nutrient solution sprayed by the nozzle 1303 is blocked by the leaves and remains on the leaves, leading to insufficient nutrition for the wheat roots. At this time, the equipment controls the operation of the electrically controlled telescopic rod, causing the L-shaped moving tube 1701 to descend, thereby increasing the pressure sensor reading to near the threshold. When the L-shaped moving tube 1701 moves back and forth, it will part the dense wheat seedlings, allowing the water and nutrient solution sprayed by the nozzle 1303 to be sprayed closer to the roots of the seedlings. This makes it easier for the water and nutrient solution to flow into the soil and be absorbed by the roots of the seedlings, thus promoting the growth of the seedlings.

[0065] When the wheat finishes heading and enters the flowering stage, the equipment controls the operation of the electrically controlled telescopic rod, causing the L-shaped moving tube 1701 to rise. This reduces the pressure sensor reading to one-third of the threshold. At this point, the pressure sensor is primarily acting on the wheat awns. As the L-shaped moving tube 1701 moves back and forth, the elastic rope 1714 between the two branch tubes 1702 acts on the wheat ears, thus pollinating them and reducing the need for manual pollination. Simultaneously, the second cylinder 26 in the spraying assembly 13 continues to operate, while the second water pump 11 stops. The reciprocating movement of the L-shaped moving tube 1701 causes the elastic rope 1714 to pollinate the wheat ears. During the pollination process, due to the varying heights of the wheat seedlings, when the pressure sensor reading is below 1 / 3 of the threshold, it indicates that the seedlings at the corresponding pressure sensor location are relatively low. In this case, the equipment controls the electromagnets on the spraying connecting pipes 1301 at the top of the branch pipes 1702 on both sides of the pressure sensor location to be energized. After the electromagnets are energized, they generate a downward repulsive force on the cutter 1711, causing the branch pipes 1702 to rotate downwards. This lowers the height of the elastic rope 1714, which then pollinates the lower-height wheat seedlings. This allows the equipment to precisely control the pollination process based on the height of the wheat seedlings, improving the accuracy of the equipment.

[0066] This invention, by incorporating pressure sensors, resistance sensors, electromagnets, elastic ropes 1714, and cutters 1711, enables the equipment to loosen compacted soil when spraying water and nutrient solution onto wheat seedlings. Furthermore, during wheat growth, the sprayed water and nutrient solution directly act on the soil around the seedling roots, reducing waste caused by water and nutrient solution adhering to the seedling leaves. It also allows for pollination of wheat after the heading stage. Moreover, when dealing with seedlings of varying growth rates, the height of the elastic ropes 1714 is adjusted for pollination, making the equipment more precise during use and improving its wheat cultivation effectiveness.

[0067] Example 3

[0068] A method for using a wheat stress-resistant cultivation device, comprising the following steps:

[0069] Step 1: Plant the wheat neatly in the cultivation box 1, and spray it with nutrient solution and water regularly with the help of the spraying component 13, so that the water and nutrient solution fall accurately into the soil below the spraying component 13, thus completing the spraying of nutrient solution and water.

[0070] Step 2: During the wheat growth process, with the assistance of the return component 17, the water, soil and nutrient solution collected in the collection box 4 are transported back to the soil at the top of the net 15 for reuse.

[0071] Step 3: During the operation of the return component 17, the soil collected in the collection box 4 is crushed with the assistance of the surrounding crushing component 23, which improves the soil crushing effect and ensures that the soil can be smoothly transported to the branch pipe 1702 to complete the return transport of the soil.

[0072] Step 4: During the wheat heading process, the return component 17 and the spraying component 13 work together to allow the return component 17 to open up the leaves of the wheat seedlings so that the water and nutrient solution sprayed by the spraying component 13 can directly act on the soil at the roots of the wheat seedlings, reducing the waste of water and nutrient solution.

[0073] Step 5: During the wheat flowering process, the height of the elastic rope 1714 in the reflux component 17 is controlled by the electromagnet in the spray component 13 through the cooperation of the reflux component 17 and the spray component 13, so that the elastic rope 1714 can accurately pollinate the wheat ears.
