An array-type multi-channel intelligent precision fertilizer and its usage method

Abstract

This invention relates to the field of multi-channel fertilization. It discloses an array-type multi-channel intelligent precision fertilization machine and its usage method. The problem this invention addresses is that existing multi-channel fertilization methods waste water resources, and the simultaneous application of multiple channels during fertilization introduces the possibility of sedimentation and clogging of drip irrigation nozzles. Clogging can pressurize other drip irrigation pipes, potentially causing further blockages, and hinders timely maintenance. This invention addresses this by sequentially discharging equal amounts of fertilizer from interconnected pipes and opening the drip irrigation pipes sequentially, reducing the likelihood of fertilizer sedimentation and nozzle clogging. Furthermore, since only one pipe is involved at a time, troubleshooting and clearing blockages are much easier.

Description

Technical Field

[0001] This invention relates to the field of multi-channel fertilization, specifically to an array-type multi-channel intelligent precision fertilization machine and its usage method. Background Technology

[0002] Currently, in ecological restoration efforts in arid and semi-arid regions, methods such as furrow irrigation, drip irrigation, sprinkler irrigation networks, and sprinkler ring irrigation are used for plant sowing and seedling planting. Large-scale seedling cultivation bases, artificial pasture planting bases, and crop planting land are irrigated using sprinkler rings. However, due to the low and uneven rainfall in arid and semi-arid regions, the increase in extreme weather events, strong winds and dry conditions, long and intense sunshine hours, high surface temperatures, high water evaporation, and high soil sand content, the soil cannot retain sufficient water. A comparison of the growth of forest products, pasture, and crops with water consumption reveals a significant increase in water resource consumption.

[0003] When existing water and fertilizer systems use multiple channels for fertilization, fertilization will waste water resources. In addition, fertilization is generally carried out simultaneously through multiple channels. During the fertilization process, there is a possibility that sediment may settle and clog the nozzles in the drip irrigation pipes. If a blockage occurs, it will pressurize the other drip irrigation pipes, which may cause the other pipes to become blocked as well. Furthermore, it is inconvenient to maintain the blocked drip irrigation pipes in a timely manner. Summary of the Invention

[0011] Preferably, a pressure spring is fixedly connected to the wedge-shaped block, and the two ends of the pressure spring are respectively connected to the wedge-shaped block and the movable frame. A limiting frame is also slidably arranged on the movable frame and perpendicular to the wedge-shaped block. A limiting rod is fixedly connected to the limiting frame and slides with the movable frame. A connecting spring is sleeved on the limiting rod, and the two ends of the connecting spring are respectively connected to the limiting frame and the movable frame. An arc-shaped notch is opened on the wedge-shaped block. A locking rod is fixedly connected to the limiting frame and engages with the notch.

[0012] Preferably, an adjustment plate is slidably provided on the inner wall of the construction support, the adjustment plate is provided with an inclined groove, and a limit wheel is rotatably provided on the side wall of the movable toothed plate, with the limit wheel extending into the inclined groove.

A compression spring is sleeved on the abutment rod, and the two ends of the compression spring are respectively connected to the abutment rod and the construction support. An inclined plate is provided on the side wall of the adjusting plate, which abuts against the upper end of the abutment rod. The number of inclined plates on the side wall of the adjusting plate is the same as the number of abutment rods on the multiple control components. After one inclined plate separates from the abutment rod on the control component, the movement of the adjusting plate causes another inclined plate to contact the corresponding abutment rod.

[0014] Preferably, the method of using the array-type multi-channel intelligent precision fertilizer includes the following steps:

[0015] S1: At the bottom of the water-fertilizer storage and infiltration channel, lay a 3cm to 10cm thick layer of water-storage and infiltration nutrient soil. On top of the water-storage and infiltration nutrient soil, lay a straw mat, then a layer of plant debris, and then another 3cm to 15cm thick layer of water-storage and infiltration nutrient soil. By following this laying method, depending on the soil conditions of the site, water will not seep into the sand and gravel layer at the bottom of the channel.

[0016] S2: Lay 1 to 5 layers of straw mats. In the water storage and infiltration channels on both sides of the straw mats, lay a layer of straw mats on top of the water storage and infiltration channels, and then lay 3cm to 10cm thick water storage and infiltration nutrient soil. Depending on the soil type and the planted plants, lay 1 to 3 layers to form a water and fertilizer storage and infiltration channel that is leak-proof at the bottom and leaks water and fertilizer on the top and sides, and intercepts rainwater and snowmelt.

[0017] S3: The fertilizer applicator feeds fertilizer into the water inlet pipe through the feed pipe, and then transports water and fertilizer to the connecting water pipe through the water inlet pipe. After mixing, the fertilizer flows from the connecting water pipe into the horizontal pipe, and the drip irrigation pipe drips the fertilizer into the water storage and infiltration channel. The water storage and infiltration channel can be rectangular or circular. The water storage and infiltration channel is woven from bamboo strips and plant branches. Water is replenished by using the gaps between the branches, boards and square grooves. Before the water storage and infiltration channel is installed, it is wrapped with branches and straw mats to prevent mud and sand from entering.

[0018] S4: Every time the intermittent frame rotates once, the mounting frame will drive the drain plunger to move towards the connecting water pipe, squeezing the fertilizer in the connecting water pipe and discharging the fertilizer in the connecting water pipe in a measured amount.

[0019] S5: The snap-fit ​​mechanism allows the drain plunger to move down at equal intervals and remain in the connecting water pipe, facilitating the subsequent discharge of the remaining fertilizer in the connecting water pipe in equal amounts.

[0020] S6: This ensures that the fertilizer discharge from the drip irrigation pipes corresponds to the equal amount of fertilizer discharged from the connecting water pipes. The fertilizer is discharged from the connecting water pipes in equal amounts, and the drip irrigation pipes are opened sequentially, reducing the possibility of fertilizer settling in the drip irrigation pipes and clogging the nozzles.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In this invention, the functions of the water storage and infiltration channel are as follows: First, it supports a water-carrying space in the soil below ground, transporting water and fertilizer to a position 5m to 20m inside the water channel, so that the entire water and fertilizer storage and infiltration channel is filled with water; second, it allows water to seep into the soil above and on both sides through water-storing nutrient soil, straw mats, and small water storage and infiltration channels; third, it intercepts and stores rainwater and snowmelt in the water and fertilizer storage and infiltration channel, providing moisture for plant root soil during the dry season; fourth, the water storage and infiltration channel can withstand greater pressure, and the supporting rings, branches, and poles have a certain degree of elasticity, and can return to their original shape after deformation.

[0023] In this invention, fertilizer is dripped into the water storage and infiltration channel through a drip irrigation pipe. The water storage and infiltration channel can be rectangular or circular and is made of bamboo strips, wood strips, and plant branches. Water is replenished by using the gaps between the branches, boards, and square groove holes. Before the water storage and infiltration channel is installed, it is wrapped with branches and straw mats to prevent mud and sand from entering.

[0024] In this invention, after the fertilizer in the connecting water pipe is discharged, when the next batch of fertilizer is discharged in equal amounts under the drive of the stepper motor, the moving toothed plate moves downward at equal intervals. This causes the adjusting plate to move, and the inclined plate on the adjusting plate that contacts the first control component separates from the abutment rod. The other inclined plate then contacts the abutment rod on the second control component, thereby enabling the second abutment rod to drive the second pressing valve to open the corresponding drip irrigation pipe for discharge. This ensures that the equal amounts of fertilizer discharged from the drip irrigation pipe correspond to the equal amounts discharged from the connecting water pipe. By sequentially using this method, equal amounts of fertilizer are discharged from the connecting water pipe, and the drip irrigation pipes are opened sequentially. This reduces the possibility of fertilizer settling in the drip irrigation pipe and clogging the nozzles. Furthermore, if a blockage occurs, since only one pipe is involved each time, it is easier to troubleshoot and clean the blockage point, allowing for quick location and resolution of the problem, thus reducing maintenance and time costs.

[0025] In this invention, fertilizer is discharged in equal amounts from the connecting water pipe in this manner, and the drip irrigation pipes are opened sequentially. This reduces the possibility of fertilizer settling in the drip irrigation pipes and clogging the nozzles. Furthermore, if a blockage occurs, since only one pipe is involved each time, it is easier to troubleshoot and clean the blockage point, allowing for quick location and resolution of the problem, thus reducing maintenance and time costs.

[0026] In this invention, sequential drip irrigation and fertilization can be carried out in stages and by region according to the water and fertilizer requirements of crops, avoiding unnecessary waste of water and fertilizer that may occur when drip irrigation and fertilization are carried out on multiple pipelines at the same time.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1 to 13This invention provides a technical solution: an array-type multi-channel intelligent precision fertilizer and its usage method, including a construction support 1, a water and fertilizer storage and infiltration channel 11 is dug horizontally on one side of the construction support 1, water-proof dams 12 are provided at equal intervals on the water and fertilizer storage and infiltration channel 11, a water storage and infiltration channel 13 is laid in each water-proof dam 12, a drip irrigation pipe 14 is extended in the water storage and infiltration channel 13, a press valve 15 is provided at the end of the drip irrigation pipe 14, and a fertilizer applicator 16 is fixedly connected to the top of the construction support 1;

[0043] The top of the construction support 1 is rotatably equipped with a fertilizer mixing component 2. The inner wall of the construction support 1 is equipped with a control component 5 that abuts against a pressure valve 15. The inner wall of the construction support 1 is also equipped with an intermittent drainage component 3 that is in transmission cooperation with the fertilizer mixing component 2.

[0044] In this embodiment, a feeding pipe 17 is fixedly installed on the side wall of the fertilizer applicator 16, and a water inlet pipe 18 is also installed on the construction support 1. The feeding pipe 17 is connected to the water inlet pipe 18. A connecting water pipe 19 is also installed on the inner wall of the construction support 1. A horizontal pipe 110 is fixedly connected to the bottom of the connecting water pipe 19. The horizontal pipe 110 is connected to several drip irrigation pipes 14. The water inlet pipe 18 is connected to the connecting water pipe 19. The fertilizer mixing component 2 extends toward the connecting water pipe 19 to mix the water and fertilizer in the connecting water pipe 19. The press valve 15 is located at the connection between the drip irrigation pipe 14 and the horizontal pipe 110.

[0045] The fertilizer mixing component 2 includes a stepper motor 21 fixedly connected to the top of the construction support 1. The main shaft of the stepper motor 21 is connected to a transmission rod 22. The transmission rod 22 is rotatably connected to the water pipe 19 and extends into the water pipe 19.

[0046] From the bottom of the water and fertilizer storage and infiltration channel, lay a 3cm to 10cm thick layer of water-storing and infiltration nutrient soil upwards. On top of the water-storing and infiltration nutrient soil, lay straw mats, then a layer of plant debris, and then another 3cm to 15cm thick layer of water-storing and infiltration nutrient soil. Following this laying method, depending on the soil conditions of the site, water will not seep into the sand and gravel layer at the bottom of the channel. Lay 1 to 5 layers of straw mats. In the water storage and infiltration channels 13 on both sides of the straw mats, lay a layer of straw mats on top of the water storage and infiltration channels 13, and then lay a 3cm to 10cm thick layer of water-storing and infiltration nutrient soil. Depending on the soil quality and the plants planted, lay 1 to 3 layers to form a water and fertilizer storage and infiltration channel that is leak-proof at the bottom and leaks water and fertilizer on the top and sides, while intercepting rainwater and snowmelt.

[0047] The fertilizer applicator 16 feeds fertilizer into the water inlet pipe 18 through the feed pipe 17. The water inlet pipe 18 then transports the fertilizer and water to the connecting water pipe 19. Driven by the stepper motor 21, the transmission rod 22 rotates in the connecting water pipe 19 to mix the fertilizer and water. The mixed fertilizer flows from the connecting water pipe 19 into the horizontal pipe 110, which then sends the fertilizer to the drip irrigation pipe 14. The fertilizer is then dripped into the water storage and infiltration channel 13 through the drip irrigation pipe 14. The water storage and infiltration channel 13 can be rectangular or circular. It is made of bamboo strips and plant branches. Water is replenished by using the gaps between the branches, boards, and square grooves. Before installation, the water storage and infiltration channel 13 is wrapped with branches and straw mats to prevent the entry of mud and sand.

[0048] In this embodiment, the intermittent drainage component 3 includes an intermittent frame 31 that is shaft-connected to the transmission rod 22. A rotating rod 32 is rotatably provided on the inner top of the construction support 1. An intermittent rotating disk 33 is shaft-connected to the rotating rod 32. A plurality of intermittent grooves 34 are formed around the circumference of the intermittent rotating disk 33. The intermittent rotating disk 33 abuts against the intermittent grooves 34.

[0049] A first helical gear 35 is also shaft-connected to the rotating rod 32. A rotating rod 36 is rotatably mounted on the inner wall of the construction support 1. A second helical gear 37 is shaft-connected to the rotating rod 36, and the second helical gear 37 meshes with the first helical gear 35. A one-way bearing 38 is also shaft-connected to the rotating rod 36. A spur gear 39 is fixedly mounted on the one-way bearing 38. A movable toothed plate 310 is longitudinally slidably connected to the construction support 1. The movable toothed plate 310 meshes with the spur gear 39. A movable rod 311 is fixedly connected to the top of the movable toothed plate 310. The rod 311 extends toward the top of the construction support 1, and a return spring 312 is sleeved on the moving rod 311. The two ends of the return spring 312 are respectively connected to the top of the moving rod 311 and the construction support 1. The moving rod 311 is also fixedly connected to the mounting bracket 313. A drain plunger 314 is slidably arranged on the inner wall of the connecting water pipe 19. A squeeze valve is arranged at the bottom of the connecting water pipe 19. The drain plunger 314 is connected to the mounting bracket 313, and the drain plunger 314 is rotatably engaged with the transmission rod 22. A snap-fit ​​piece 4 is also connected to the moving toothed plate 310.

[0050] When the stepper motor 21 drives the transmission rod 22 to rotate, the transmission rod 22 will drive the intermittent frame 31 to rotate. When the intermittent frame 31 rotates one revolution, it will contact the intermittent groove 34 on the intermittent rotating disk 33, thereby driving the intermittent rotating disk 33 to rotate. The rotation of the intermittent rotating disk 33 will drive the rotating rod 32 to rotate, and the rotating rod 32 will drive the first helical gear 35 to rotate. The first helical gear 35 will contact and rotate with the second helical gear 37, driving the rotating rod 36 to rotate. The rotation of the rotating rod 36 will cause the one-way bearing 38 to rotate. The spur gear 39 fixedly installed on the one-way bearing 38 will drive the moving gear plate 310 to move downward on the construction support 1, which is fixedly connected to the moving gear plate 310. The mounting bracket 313 on the moving rod 311 will drive the drain plunger 314 to move towards the connecting water pipe 19, squeezing the fertilizer in the connecting water pipe 19 and squeezing the fertilizer out from the squeezing valve and flowing into the horizontal pipe 110. Since the intermittent rotating disk 33 rotates at the same angle each time, the intermittent rotating disk 33 drives the moving toothed plate 310 to move down the same distance each time, so that the moving toothed plate 310 drives the drain plunger 314 to discharge the fertilizer in the connecting water pipe 19 in a quantitative manner, which is conducive to realizing automated and precise fertilizer management. In addition, by combining with the control component 5, the amount of fertilizer discharged from each drip irrigation pipe 14 is the same under the drive of the control component 5.

[0051] In this embodiment, the snap-fit ​​component 4 includes a movable frame 41 fixedly connected to the outer wall of the movable toothed plate 310 on the side away from the spur gear 39. A support frame 42 is fixedly provided on the inner wall of the construction support 1. The movable frame 41 and the support frame 42 are slidably engaged. The support frame 42 is provided with slots 43 at equal intervals. A wedge-shaped snap-fit ​​block 44 is slidably provided on the movable frame 41, and the wedge-shaped snap-fit ​​block 44 is engaged with the slot 43 on the support frame 42.

[0052] A pressure spring 45 is fixedly connected to the wedge-shaped locking block 44. The two ends of the pressure spring 45 are respectively connected to the wedge-shaped locking block 44 and the moving frame 41. A limiting frame 46 is also slidably arranged on the moving frame 41 and is perpendicular to the wedge-shaped locking block 44. A limiting rod 47 is fixedly connected to the limiting frame 46 and slides with the moving frame 41. A connecting spring 48 is sleeved on the limiting rod 47 and the two ends of the connecting spring 48 are respectively connected to the limiting frame 46 and the moving frame 41. An arc-shaped notch 49 is opened on the wedge-shaped locking block 44. A locking rod 410 is fixedly connected to the limiting frame 46 and engages with the notch 49. An inclined stop block 411 is also fixedly arranged on the support frame 42 and abuts against the wedge-shaped locking block 44.

[0053] When the moving toothed plate 310 moves downward, the moving frame 41 set on the moving toothed plate 310 will move downward on the support frame 42. The moving toothed plate 310 moves downward at equal intervals under the drive of the intermittent rotating disk 33, and the moving frame 41 moves at equal intervals on the support frame 42. The wedge-shaped locking block 44 slidably set on the moving frame 41 will be locked into the corresponding locking groove 43 set on the support frame 42. The wedge-shaped locking block 44 moves towards the locking groove 43 under the drive of the pressure spring 45. The plane of the wedge-shaped locking block 44 abuts against the locking groove 43, thereby limiting the moving frame 41 under the restriction of the locking groove 43 on the support frame 42, preventing the moving toothed plate 310 from moving upward and resetting under the drive of the reset spring 312 on the moving rod 311, so that the drain plunger 314 moves downward at equal intervals and stays in the connecting water pipe 19, which is convenient for the subsequent equal discharge of the remaining fertilizer in the connecting water pipe 19.

[0054] In this embodiment, an adjustment plate 412 is slidably arranged on the inner wall of the construction support 1. An inclined groove 413 is provided on the adjustment plate 412. A limit wheel 414 is rotatably arranged on the side wall of the moving toothed plate 310, and the limit wheel 414 extends toward the inclined groove 413.

[0055] The control component 5 includes an abutment rod 51 slidably mounted on the construction support 1. The bottom of the abutment rod 51 contacts the control end of the press valve 15. A compression spring 52 is sleeved on the abutment rod 51. The two ends of the compression spring 52 are respectively connected to the abutment rod 51 and the construction support 1. An inclined plate 53 is provided on the side wall of the adjusting plate 412, which abuts against the upper end of the abutment rod 51. The number of inclined plates 53 on the side wall of the adjusting plate 412 is the same as the number of abutment rods 51 on several control components 5. After one inclined plate 53 separates from the abutment rod 51 on the control component 5, the movement of the adjusting plate 412 causes another inclined plate 53 to contact the corresponding abutment rod 51.

[0056] When the moving toothed plate 310 moves downward at equal intervals, the limiting wheel 414 on the moving toothed plate 310 moves in the inclined groove 413 on the adjusting plate 412, thereby allowing the adjusting plate 412 to slide laterally on the construction support 1. When the adjusting plate 412 moves, the inclined plate 53 set on the side wall of the adjusting plate 412 will contact the abutment rod 51 on the first control component 5, thereby causing the abutment rod 51 to press down towards one end of the press valve 15. After the abutment rod 51 presses down and contacts the press valve 15, the fertilizer in the horizontal pipe 110 can enter the drip irrigation pipe 14, so that the drip irrigation pipe 14 can drip the fertilizer into the water storage and infiltration channel 13. After the fertilizer in the connecting water pipe 19 is discharged, the moving toothed plate 310 will discharge the next amount of fertilizer under the drive of the stepper motor 21. When the adjustment plate 412 moves downward, the inclined plate 53 on the adjustment plate 412 that is in contact with the first control element 5 will separate from the abutment rod 51. The other inclined plate 53 will then contact the abutment rod 51 on the second control element 5. This will cause the second abutment rod 51 to drive the second press valve 15 to open the corresponding drip irrigation pipe 14 to discharge fertilizer. This will make the fertilizer discharge in the drip irrigation pipe 14 correspond to the fertilizer discharge in the connecting water pipe 19. In this way, the fertilizer will be discharged from the connecting water pipe 19 in equal amounts and the drip irrigation pipe 14 will be opened in sequence. This will reduce the possibility of fertilizer settling in the drip irrigation pipe 14 and clogging the nozzle. If a blockage occurs, since only one pipe is involved each time, it is easier to check and clean the blockage point. This will allow for quick location and resolution of the problem, reducing maintenance and time costs.

[0057] Fertilizer drip irrigation can be carried out in stages and by area according to the water and fertilizer requirements of crops, avoiding unnecessary waste of water and fertilizer that may occur when fertilizing and drip irrigating multiple pipelines at the same time.

[0058] When all the fertilizer in the connecting water pipe 19 is discharged, the rotating rod 36 rotates, causing the moving toothed plate 310 to move the moving frame 41 on the support frame 42 toward the inclined block 411. At this time, after the wedge-shaped locking block 44 contacts the inclined block 411, it will move on the moving frame 41. At this time, the notch 49 on the wedge-shaped locking block 44 will contact the locking rod 410 on the limiting frame 46. After the locking rod 410 aligns with the notch 49 of the wedge-shaped locking block 44, it will limit the wedge-shaped locking block 44. At this time, the wedge-shaped locking block 44 does not contact the slot 43 on the support frame 42. Upon reconnection, the moving toothed plate 310 will move upward and reset under the action of the reset spring 312 on the moving rod 311. The upward reset of the moving toothed plate 310 will drive the drain plunger 314 to move upward, thereby restoring the drain plunger 314 to its original state. When the moving toothed plate 310 moves upward and resets, it will drive the spur gear 39 to rotate the one-way shaft, which will not affect the rotating rod 36. After the moving frame 41 moves upward and resets, the limit frame 46 will contact the end of the support frame 42, which will cause the locking rod 410 to disengage from the notch 49 of the wedge-shaped locking block 44, thus facilitating subsequent fertilization operations.

[0059] The method of use and advantages of this invention: The working process of this array-type multi-channel intelligent precision fertilizer is as follows:

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown:

[0061] S1: At the bottom of the water-fertilizer storage and infiltration channel, lay a 3cm to 10cm thick layer of water-storage and infiltration nutrient soil. On top of the water-storage and infiltration nutrient soil, lay a straw mat, then a layer of plant debris, and then another 3cm to 15cm thick layer of water-storage and infiltration nutrient soil. By following this laying method, depending on the soil conditions of the site, water will not seep into the sand and gravel layer at the bottom of the channel.

[0062] S2: Lay 1 to 5 layers of straw mats, and lay a layer of straw mats on the infiltration channels 13 on both sides of the straw mats. Then lay a 3cm to 10cm thick layer of infiltration nutrient soil. Lay 1 to 3 layers according to the soil type and the planted plants to form a water and fertilizer infiltration channel that is leak-proof at the bottom and leaks water and fertilizer on the top and sides, and intercepts rainwater and snowmelt.

[0063] S3: The fertilizer applicator 16 feeds fertilizer into the water inlet pipe 18 through the feed pipe 17, and then transports water and fertilizer into the connecting water pipe 19 through the water inlet pipe 18. After mixing, the fertilizer flows from the connecting water pipe 19 into the horizontal pipe 110. The drip irrigation pipe 14 drips the fertilizer into the water storage and infiltration channel 13. The water storage and infiltration channel 13 can be rectangular or circular. The water storage and infiltration channel 13 is woven from bamboo strips and plant branches. Water is replenished by using the gaps between the branches, boards and square grooves. Before the water storage and infiltration channel 13 is installed, it is wrapped with branches and straw mats to prevent mud and sand from entering.

[0064] S4: For each rotation of the intermittent frame 31, the mounting frame 313 will drive the drain plunger 314 to move toward the connecting water pipe 19, squeezing the fertilizer in the connecting water pipe 19 and discharging the fertilizer in the connecting water pipe 19 in a measured amount.

[0065] S5: The setting of the snap-fit ​​part 4 allows the drain plunger 314 to move down at equal intervals and stay in the connecting water pipe 19, which facilitates the subsequent discharge of the remaining fertilizer in the connecting water pipe 19 in equal amounts.

[0066] S6: Ensure that the fertilizer discharge in the drip irrigation pipe 14 corresponds to the fertilizer discharge in the connecting water pipe 19, and that the fertilizer is discharged from the connecting water pipe 19 in equal amounts, and that the drip irrigation pipe 14 is opened sequentially, thereby reducing the possibility of fertilizer settling in the drip irrigation pipe 14 and clogging the nozzles.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. 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 preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
