One motor is used to move, water, and fertilize the plants, while another motor is used to lift the fertilizer. This effectively reduces the power requirements and enhances the linkage and cooperation between the devices, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for cultivating and raising seedlings of Tatsoi, comprising the following steps:

[0006] S1: Seedbed selection: Seedbeds should be selected from those that have not been used to grow vegetables of the same family. Loam soil with strong water and fertilizer retention capacity and good drainage is preferred.

[0007] S2: Seedling time and varieties: Autumn sowing in August-September is suitable for open field cultivation, while winter sowing in October-November is suitable for plastic greenhouse cultivation. For winter sowing, choose tatsoi varieties with strong cold resistance and high marketability.

[0008] S3: Sowing: Soak the seeds in clean water for 1 hour before sowing. Water the seedbed before sowing and keep the soil in the seedbed moist. Sow the seeds of Tatsoi on the moist soil and cover with fine soil after sowing. The sowing amount of Tatsoi per seedbed is 1 kg.

[0009] S4: Seedling management: Water every 3-5 days after emergence to keep the soil moist. When 1-2 true leaves have grown, perform the first thinning, with a seedling spacing of 1.5-3.3 cm. When 3-4 true leaves have grown, perform the second thinning, with a seedling spacing of 6-7 cm. When the first true leaf unfolds, apply 0.5 kg of urea per bed in conjunction with watering. When 3-4 true leaves have grown, weed in time and apply 1 kg of urea per bed in conjunction with watering. When the seedlings are 40-50 days old and have 4-5 true leaves, they can be transplanted to their final location.

[0010] S5: Fertilization: After the seedlings of the Chinese cabbage are established, apply a light fertilizer once, with 0.7-0.8 kg of compound fertilizer per bed. Later, you can apply fertilizer according to the growth of the seedlings, with 0.5-0.8 kg of urea each time. Keep the soil moist.

[0011] Preferably, for S1, the seedbed is fertilized before sowing, the soil of the seedbed is deeply tilled to a depth of 16-18 cm, and 30 kg of well-rotted organic fertilizer is applied to each seedbed, along with urea.

[0012] Preferably, for S2, after sowing in autumn open field cultivation, cover the soil with 1-2 cm of soil and apply a pressure of 9.8 N on the fine soil, and keep the soil moist before sowing.

[0013] Preferably, a ring of receiving grooves is provided on the bottom outer wall of the seedling bed, and a partition is provided in the middle of the receiving grooves to separate the receiving grooves and form two fertilizer troughs and water troughs side by side.

[0019] Preferably, the powertrain includes a support plate, a servo motor, a reducer, a motor shaft, and a transmission shaft. The support plate is horizontally fixed to the upper support plate. The servo motor and the reducer are mounted on the support plate. Both ends of the motor shaft are connected to the servo motor and the reducer. Both ends of the transmission shaft are connected to the reducer and the shaft of the upper moving wheel assembly. The servo motor drives the upper moving wheel assembly to move along the moving groove after the speed is reduced by the reducer.

[0020] Preferably, the fertilizer lifting assembly includes a lifting cylinder, a lifting motor, a first spiral blade, a discharge pipe, a collection box, a collection shaft, and a collection plate.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] During fertilization, the servo motor drives the motor shaft and transmission shaft to rotate. The upper and lower moving wheel sets move in one direction, while the water pump reverses and cannot pump water. The collection box collects fertilizer from the fertilizer trough as it moves. The rotating collection plate feeds the material into the lifting cylinder. The first spiral blade lifts the fertilizer upwards, through the discharge pipe, and into the positioning cylinder. The second spiral blade pushes the fertilizer further to the fertilization cylinder, which rotates in contact with the cultivation bed to achieve intermittent fertilization. During watering, the servo motor drives the motor shaft and transmission shaft to reverse, causing the upper and lower moving wheel sets to move in the other direction. The closed surface of the fertilizer trough moves forward, preventing some residual fertilizer from entering the collection box. The water pump rotates forward to pump water, achieving watering. This achieves the interconnection between the equipment structures. One motor enables movement, watering, and fertilization, while another motor lifts the fertilizer. With the help of the rotating shaft or cylinder, fertilizer collection and targeted fertilization can be achieved. Attached Figure Description

[0037] 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.

[0038] This embodiment provides the following technical solution:

[0039] A method for cultivating and raising seedlings of Tatsoi includes the following steps:

[0040] Step 1: Seedbed selection: The seedbed should be a nursery bed that has not been planted with vegetables of the same family before. It should be loam with good water and fertilizer retention and drainage. Fertilize the seedbed before sowing. The soil of the nursery bed should be deeply tilled to a depth of 16-18 cm. Apply 30 kg of decomposed organic fertilizer and urea to each nursery bed.

[0041] Step 2: Seedling time and varieties: For autumn sowing in August-September, choose open field cultivation; for winter sowing in October-November, choose plastic greenhouse cultivation. For winter sowing, choose a cold-resistant and commercially viable variety of Tatsoi. For autumn open field cultivation, cover the seeds with 1-2 cm of soil and apply 9.8 N of pressure to the fine soil. Keep the soil moist before sowing.

[0042] Step 3: Sowing: Soak the seeds in clean water for 1 hour before sowing. Water the seedbed before sowing to keep the soil moist. Sow the seeds of Tatsoi on the moist soil and cover with fine soil after sowing. The sowing amount of Tatsoi per seedbed is 1 kg.

[0043] Step 4: Seedling Management: Water every 3-5 days after emergence to keep the soil moist. When 1-2 true leaves have grown, perform the first thinning, with a seedling spacing of 1.5-3.3 cm. When 3-4 true leaves have grown, perform the second thinning, with a seedling spacing of 6-7 cm. When the first true leaf unfolds, apply 0.5 kg of urea per bed along with watering. When 3-4 true leaves have grown, weed promptly and apply 1 kg of urea per bed along with watering. When the seedlings are 40-50 days old and have 4-5 true leaves, they can be transplanted to their final location.

[0044] Step 5: Fertilization: After the seedlings of the Chinese cabbage are established, apply a light fertilizer once, with 0.7-0.8 kg of compound fertilizer per bed. Later, you can apply fertilizer according to the growth of the seedlings, with 0.5-0.8 kg of urea each time. Keep the soil moist.

[0045] To address the problems with existing methods for cultivating and raising seedlings of Tatsoi, please refer to [link / reference needed]. Figures 1-7 ;

[0046] A ring of receiving troughs 1 is set on the bottom outer wall of the seedling bed for planting and raising seedlings of Tatsoi. A partition 2 is set in the middle of the receiving troughs 1 to separate the receiving troughs 1 and form two fertilizer troughs 11 and water troughs 12 that are parallel to each other.

[0047] A ring of movable grooves 3 is provided on the outer wall of the middle part of the seedling bed. The movable component 4 is locked in the movable groove 3 and is connected to the support assembly 9. The support assembly 9 is equipped with a power assembly 5, a fertilizer lifting assembly 6, a watering assembly 7, and a fertilizer application assembly 8. The power assembly 5 is connected to the movable component 4, the watering assembly 7, and the fertilizer application assembly 8 respectively. The bottom end of the watering assembly 7 is inserted into the water trough 12. The top of the fertilizer lifting assembly 6 is connected to the fertilizer application assembly 8, and the bottom end of the fertilizer lifting assembly 6 is inserted into the fertilizer trough 11. The fertilizer application assembly 8 and the watering assembly 7 are arranged horizontally side by side on the seedling bed.

[0048] The seedling bed is in the shape of a racetrack with semicircles at both ends and a straight track in the middle. The receiving trough 1, the moving trough 3, the fertilizer trough 11 and the water trough 12 are all in the shape of a racetrack.

[0049] Specifically, the two sides of the seedling bed are semi-circular, so that the watering assembly 7 and the fertilizer assembly 8 can move smoothly when passing through the semi-circle, and the watering assembly 7 and the fertilizer assembly 8 can water all parts of the seedling bed.

[0050] The support assembly 9 includes an upper support plate 91, a lower support plate 92 and a connecting plate 93, with the upper support plate 91 and the lower support plate 92 fixed together by the connecting plate 93.

[0051] The moving assembly 4 includes an upper moving wheel set 41 and a lower moving wheel set 42. The shaft of the upper moving wheel set 41 passes through the upper support plate 91, and the shaft of the lower moving wheel set 42 passes into the bearing of the lower support plate 92. The upper moving wheel set 41 and the lower moving wheel set 42 are in contact with the upper and lower surfaces of the moving groove 3.

[0052] Specifically, the upper moving wheel set 41 and the lower moving wheel set 42 clamp the moving groove 3, so that the equipment will not shake when it moves, and the stability is good. A raised baffle is provided on the edge of the moving groove 3 to restrict the upper moving wheel set 41 and the lower moving wheel set 42 when they pass through the semicircle. In addition, a middle wheel set is provided on the connecting plate 93, which contacts the side of the moving groove 3 and serves as a guide.

[0053] The powertrain 5 includes a support plate 51, a servo motor 52, a reducer 53, a motor shaft 54, and a transmission shaft 55. The support plate 51 is horizontally fixed on the upper support plate 91. The servo motor 52 and the reducer 53 are mounted on the support plate 51. The two ends of the motor shaft 54 ​​are connected to the servo motor 52 and the reducer 53. The two ends of the transmission shaft 55 are connected to the shafts of the reducer 53 and the upper moving wheel set 41. The servo motor 52 drives the upper moving wheel set 41 to move along the moving groove 3 after the speed is reduced by the reducer 53.

[0054] Specifically, after the speed reducer 53 reduces the speed, the equipment moves at a slower speed, preventing the equipment from moving too fast and causing watering and fertilizing areas to be missed.

[0055] The fertilizer lifting assembly 6 includes a lifting cylinder 61, a lifting motor 62, a first spiral blade 63, a discharge pipe 64, a collection box 65, a collection shaft 66, and a collection plate 67. The lifting cylinder 61 is fixed to the outer wall of the lower support plate 92. The lifting motor 62 is located at the top of the lifting cylinder 61. The discharge pipe 64 is inclined and connected to the top of the lifting cylinder 61. The shaft of the lifting motor 62 is connected to the first spiral blade 63 inside the lifting cylinder 61. The bottom end of the lifting cylinder 61 is inserted into the collection box 65.

[0056] The collection box 65 is inserted into the fertilizer trough 11. The inside of the collection box 65 is provided with a collection chamber that communicates with the lifting cylinder 61. The opening on one side of the collection box 65 is connected to the collection box 65. One end of the collection shaft 66 passes through the collection chamber and is connected to several collection plates 67. The gear on the other end of the collection shaft 66 meshes with the rack at the top of the partition plate 2. When the collection box 65, the lifting cylinder 61 and the lower support plate 92 move synchronously, the collection shaft 66 rotates to drive the collection plates 67 to rotate and push the fertilizer into the lifting cylinder 61 and rise to be discharged from the discharge pipe 64.

[0057] Specifically, by utilizing the structure of gears and racks, the material collection box 65 can be moved while the internal material collection plate 67 rotates when the equipment moves. Fertilizer can be fed into the lifting cylinder 61 without the need for power equipment. The fertilizer is then transported by the lifting cylinder 61 rising.

[0058] The watering assembly 7 includes a water pump 71, a water pumping pipe 72 and a watering pipe 73. The water pump 71 is mounted on the lower support plate 92. Both ends of the water pump 71 are connected to the water pumping pipe 72 and the watering pipe 73, and the shaft of the water pump 71 is connected to the shaft of the motor shaft 54 ​​via a belt.

[0059] The bottom end of the water pump 72 is below the liquid level of the water tank 12. The top of the watering pipe 73 is L-shaped and extends to the center line of the seedling bed. The bottom of the horizontal watering pipe 73 has several nozzles, which face the seedling bed.

[0060] Specifically, the high rotational speed of the motor shaft 54 ​​can effectively drive the water pump 71 to work, thereby creating a vacuum and drawing water from the water tank 12 to achieve the watering action.

[0061] The fertilization assembly 8 includes a positioning plate 81, a positioning cylinder 82, a second spiral blade 83, a fertilization cylinder 84, and a positioning ring 85. The positioning plate 81 is fixed on the upper support plate 91. The positioning plate 81 is penetrated by the positioning cylinder 82. The top of the positioning cylinder 82 is connected to the feed pipe 64. The positioning ring 85 is fitted on the port of the positioning cylinder 82. The positioning cylinder 82 is movably connected to the fertilization cylinder 84 through the positioning ring 85. The outer wall of the fertilization cylinder 84 is in contact with the edge of the seedling bed.

[0062] The second helical blade 83 extends through the positioning cylinder 82 into the fertilizer cylinder 84, and the shaft of the second helical blade 83 passes through the positioning cylinder 82 and is connected to the drive shaft 55 by a belt.

[0063] The ports of the positioning plate 81 and the fertilizer cylinder 84 are complementary, and their inner diameters are the same. The fertilizer cylinder 84 has a row of fertilizer holes, and the spacing between the fertilizer holes is the same as the spacing between each row of *Tatsoi* seeds. The length of one rotation of the fertilizer cylinder 84 is equal to the spacing between each row of *Tatsoi* seeds.

[0064] After the drive shaft 55 slows down, it drives the second spiral blade 83 to rotate, which delivers the fertilizer in the positioning cylinder 82 to the fertilizer cylinder 84. Since the fertilizer cylinder 84 is fitted on the positioning cylinder 82, the fertilizer cylinder 84 contacts the edge of the cultivation bed during the movement of the equipment. Under the action of friction, the fertilizer cylinder 84 also rotates, which drives the fertilizer hole of the fertilizer cylinder 84 to rotate, so as to achieve the purpose of intermittent fertilization. It is suitable for multi-row planting of Tatsoi.

[0065] Working principle: Appropriate amounts of fertilizer and water are placed in fertilizer tank 11 and water tank 12 respectively. During fertilization, servo motor 52 drives motor shaft 54 ​​and transmission shaft 55 to rotate. The upper moving wheel set 41 and lower moving wheel set 42 move in one direction, while water pump 71 reverses and cannot pump water. The opening of collection box 65 collects fertilizer from fertilizer tank 11 during movement. Since collection shaft 66 also rotates when rack and pinion meshes, collection plate 67 rotates to feed material into lifting cylinder 61. The first spiral blade 63 rotates to lift fertilizer through discharge pipe 64 and into positioning cylinder 82. The second spiral blade 83 continues to push fertilizer to fertilizer cylinder 84. Fertilizer cylinder 84 contacts and rotates with the cultivation bed to achieve intermittent fertilization.

[0066] When watering, the servo motor 52 drives the motor shaft 54 ​​and the transmission shaft 55 to reverse, so the upper moving wheel set 41 and the lower moving wheel set 42 move in the other direction, the closed surface of the fertilizer tank 11 moves forward, and some residual fertilizer cannot enter the collection box 65. The water pump 71 rotates forward to pump water, thus realizing watering.
