Description

Technical Field

[0001] The present invention relates to the technical field of flue-cured tobacco seedling transplanting, and specifically, to a method for transplanting small flue-cured tobacco seedlings through a hole in the film. Background Art

[0002] In the process of flue-cured tobacco planting, transplanting is one of the key links. There are many problems with traditional flue-cured tobacco transplanting methods. For small seedling transplanting, the technology of making a hole in the film for small seedlings under the film is an efficient and precise agricultural planting technology, which combines modern agricultural science and technology with traditional planting experience. By precisely controlling the environmental conditions and operation steps during transplanting, the survival rate of small seedlings during transplanting is ensured, their rapid growth is promoted, and ultimately the goal of high yield and high efficiency is achieved;

[0003] For the technology of making a film opening manually, the efficiency of manual film opening is low, and the quality of the openings is uneven, which affects the heat preservation, moisture preservation and weed prevention effects of the black film on the soil. On the other hand, the labor intensity of manually transplanting small flue-cured tobacco seedlings is high, and it is difficult to ensure the consistency of the transplanting depth and spacing of each tobacco seedling, which is not conducive to the later growth of tobacco seedlings and field management. If there is a technology that can make a hole in the film mechanically and transplant tobacco seedlings into the soil under the film, then the speed of transplanting small flue-cured tobacco seedlings through a hole in the film will be increased.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are:

[0023] 1. By inversely calculating the sowing time based on the transplanting period and seedling age, the seedling raising time can be accurately determined, avoiding the quality damage of tobacco seedlings due to missing the "suitable" transplanting period, laying a good foundation for subsequent growth. The requirements for land preparation and soil moisture conservation of deep plowing with a high ridging plow, short fields with long furrows, and smooth drainage and irrigation create an excellent soil environment for the growth of flue-cured tobacco, enhancing soil air permeability and water permeability, improving physical and chemical properties, facilitating the rooting of flue-cured tobacco roots and the absorption of nutrients and water. The clear hole-digging specifications ensure that there is an appropriate distance between the leaves of the tobacco seedlings and the plastic film after transplantation, and can also ensure the normal growth of tobacco seedlings under different groundwater level conditions. Reasonable operations such as watering the hole, pest control, fertilization and film covering provide suitable moisture for the growth of tobacco seedlings, reduce the threat of pests, ensure the effective utilization of fertilizers and the water retention and heat preservation effects of the plastic film;

[0024] 2. The film opening assembly composed of the first electric push rod, linear track, second electric push rod, swing rod, opening member, etc. can automatically and accurately open the black film. Compared with manual opening, it greatly improves the opening efficiency, and the opening shape is regular, which is beneficial to the maintenance and adjustment of the soil environment by the black film during the later growth of tobacco seedlings. In the seedling dropping assembly, the first limit plate, second limit plate, soil scraping plate, seedling guiding plate, guiding plate, etc. work together to accurately guide the flue-cured tobacco seedlings from the seedling tray to the soil. The arc design of the second limit plate plays a good guiding and limiting role for the tobacco seedlings to prevent them from falling; the soil scraping plate scrapes the soil before transplantation to create a suitable soil entry space for the tobacco seedlings, ensuring the accuracy of the transplantation depth and position of the tobacco seedlings, improving the survival rate of the tobacco seedlings. The controller is connected to devices such as the first electric push rod, second electric push rod, third electric push rod, and first cylinder, and at the same time, combined with the data feedback of the vision sensor, it realizes the automation and intelligence of the entire transplantation process. For example, after the vision sensor monitors that the tobacco seedlings have passed, it can automatically control the seedling baffle to block the feeding channel to prevent subsequent tobacco seedlings from entering by mistake; the auxiliary transmission shaft assists in transporting the flue-cured tobacco seedlings, making the movement of the tobacco seedlings more smooth during transplantation, further improving the transplantation efficiency and quality.

[0025] 3. After transplantation, root irrigation treatment with specific medicaments can effectively prevent and control pests and diseases, ensure the healthy growth of tobacco seedlings, and improve the yield and quality of flue-cured tobacco. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] The following combines the appended Figures 1 - 8 And the implementation manners to further illustrate the present invention.

[0037] The specific embodiment of the present invention is:

[0038] The method for transplanting flue-cured tobacco seedlings under the film with a broken opening includes the following steps:

[0039] S1: Determine the seedling raising time and conduct seedling raising;

[0040] Among them, after the tobacco seedlings enter the large cross stage, strengthen the light and ventilation in time to harden the seedlings earlier; the seedling raising time should be inversely deduced based on the transplanting period and a seedling age of 35 - 45 days.

[0041] Furthermore, due to different light and heat conditions and transplanting periods in different regions, it is necessary to determine according to local conditions. For example, if transplanting on May 1 in Xiangyun County and the seedling age is about 40 days, the sowing time is about March 20. It is necessary to accurately calculate the sowing period to avoid the tobacco seedlings from becoming weak or being scrapped due to missing the "suitable" transplanting period.

[0042] S2: Soil preparation and ridging;

[0043] Among them, soil preparation is to plow the soil to loosen it, break the plow sole, enhance air permeability and water permeability, improve physical and chemical properties, create space for the growth of crop roots, and facilitate rooting and absorption of nutrients and water; ridging is to further process the plowed land to make the soil fine and flat, and plan the shape, width, height and spacing of the appropriate soil moisture (the humidity of the soil in the field suitable for crop growth) according to the planting requirements, ensuring smooth farmland drainage and irrigation and uniform water distribution, which is beneficial to crop sowing, transplanting and growth. The requirements for soil preparation and ridging are deep plowing with a high ridger, short ridges for long fields, and smooth drainage and irrigation, creating a good soil environment for flue-cured tobacco growth; among them, due to the water and heat preservation effect of the film in the transplanting of small seedlings under the film, the transplanting period can be appropriately advanced, and the time for soil preparation and ridging should also be advanced; if it is affected by the previous crop and it is impossible to advance the soil preparation, it can be carried out according to the normal season.

[0044] S3: Digging pits. After ridging, pits are dug to set up the tobacco pits;

[0045] "Digging pits" is a term in agricultural planting, which means digging holes in the field according to specific specifications and requirements on the basis of well-prepared land and ridged land. These holes are used for transplanting crop seedlings, sowing or fertilizing and other farming operations. In the technology of transplanting small flue-cured tobacco seedlings through a hole in the film, the depth requirement for digging pits is 12 - 15 cm, and the transverse diameter requirement is 20 - 23 cm, ensuring that the leaves of the tobacco seedlings are more than 7 cm away from the plastic film after transplantation. For tobacco fields with a relatively high groundwater level, the depth requirement for digging pits can be reduced to 10 - 12 cm to prevent root rot and seedling death.

[0046] S4: Conduct pest control treatment. The pest control treatment uses nicotine emulsifiable concentrate or lambda-cyhalothrin emulsifiable concentrate to spray the tobacco pits and ridges to control underground pests;

[0047] The concentration of the nicotine emulsifiable concentrate is: 800 times the 10% nicotine emulsifiable concentrate; the concentration of the lambda-cyhalothrin emulsifiable concentrate is: 2500 times the 25 g / L lambda-cyhalothrin emulsifiable concentrate.

[0048] S5: Apply fertilizer to the tobacco pits, and cover the pits with a film after fertilization;

[0049] Among them, 50 kg of compound fertilizer is applied in a circular manner per mu (1 / 3 as base fertilizer), and then the fertilizer and the surface of the pit are covered tightly with decomposed farmyard manure or fine soil to prevent fertilizer volatilization and conserve moisture;

[0050] When covering the film, black plastic film with a light transmittance of 30% - 40% and a thickness of 0.8 - 1 μm is selected. Before covering the film, the soil on the ridge surface is sorted out, and when covering the film, the two sides are pressed tightly with soil to prevent the film from being scratched and lifted.

[0051] S6: Select suitable tobacco seedlings and place them on the tobacco seedling placement tray of the slitting and transplanting integrated machine. Use the film slitting component 3 of the slitting and transplanting integrated machine to slit the black film, and use the seedling dropping component 4 of the slitting and transplanting integrated machine to transplant the tobacco seedlings. Among them, the film slitting component 3 can slit the black film, and the seedling dropping component 4 can transplant the small seedlings in the tobacco seedling placement tray into the soil at the slitted position in the tobacco pond;

[0052] Among them, the tobacco seedlings should be selected with a seedling age of 35 - 45 days, having 4 - 5 leaves (4 leaves and 1 bud - 5 leaves and 1 bud), a seedling height of 5 - 6 cm, being stocky, with a normal green leaf color, well - developed roots, being fresh and free from diseases and pests, and having not been leaf - trimmed;

[0053] Select a suitable position and depth for slitting and transplanting according to the growth of the small seedlings and soil conditions, ensure that the roots pass through the plastic film and enter the soil, and pour a small amount of water after transplanting to make the soil and the roots closely combined

[0054] S7: Immediately lay drip irrigation after transplanting, and use drip irrigation to water, with 1.5 kg of water poured into each pond;

In the initial state, the piston rod of the first cylinder 204 is in an extended state. At this time, the first limiting plate 402, the second limiting plate 403 and the soil-pushing plate 404 are in a Figure 5In the state shown, the soil-pushing plate 404 does not contact the upper side of the membrane.

The seedlings are placed in the direction of the seedling guide plate 4051, and the seedlings slide down the slope of the feed channel 102 to the seedling guide platform 406. The first cylinder 204 drives the connecting shaft 203 and the circular shaft 4021 to move. The circular shaft 4021 moves in the fixed track 401. The circular shaft 4021 drives the first limiting plate 402 to move. The first limiting plate 402 drives the second limiting plate 403 to move.

[0070] The working process of the present invention is as follows:

[0071] First, according to the local light and heat conditions and the predetermined transplanting period, combined with a seedling age of 35 - 45 days, accurately reverse-deduce to determine the seedling raising time and carry out the seedling raising work. After the tobacco seedlings enter the big cross stage, timely strengthen the light and ventilation to carry out early hardening of the seedlings. For example, if the transplanting is on May 1 in Xiangcheng Town and the seedling age is about 40 days, the sowing time is about March 20.

[0072] Then, carry out land preparation and ridging. Plow the soil to break the plow sole, make the soil loose, enhance the air permeability and water permeability, and improve the physical and chemical properties. Then further process the plowed land to make the soil fine and flat. According to the requirements of deep plowing with a high ridging, short furrows for long fields, and smooth drainage and irrigation, plan the appropriate shape, width, height, and spacing of the furrows. Due to the water and heat preservation effect of the film in the transplanting of small seedlings under the film, the transplanting period can be appropriately advanced, and the land preparation and ridging time should also be advanced; if it is affected by the minor spring crops and the land preparation cannot be advanced, it shall be carried out according to the normal season.

[0073] After completing the whole process of soil preparation and ridging to form pits, the depth of the pits should be 12 - 15 cm (for tobacco fields with relatively high groundwater levels, the depth requirement for pit formation should be reduced to 10 - 12 cm), and the transverse diameter should be 20 - 23 cm to ensure that the leaves of tobacco seedlings are more than 7 cm away from the plastic film after transplanting. After forming the pits, spray the tobacco pits and ridges with 600 - 800 times the liquid of 10% nicotine emulsifiable concentrate or 2500 times the liquid of 25 g / L lambda-cyhalothrin emulsifiable concentrate for pest control to prevent underground pests.

[0074] Subsequently, fertilize the tobacco pits, applying 50 kg of compound fertilizer per mu in a circular manner (1 / 3 as base fertilizer), and then cover the fertilizer and the surface of the pit with well-rotted farmyard manure or fine soil to prevent fertilizer volatilization and conserve moisture. Then, select a black plastic film with a light transmittance of 30% - 40% and a thickness of 0.8 - 1 μm for covering the film. Before covering the film, level the soil on the ridge surface. When covering the film, press the two sides firmly with soil to prevent the film from being scratched or warped.

[0075] Select tobacco seedlings with a seedling age of 35 - 45 days, having 4 - 5 leaves (4 leaves and 1 bud - 5 leaves and 1 bud), a seedling height of 5 - 6 cm, being stocky, with normal green leaves, well-developed roots, clear and free of diseases and pests, and not having been leaf-cut, and place them on the tobacco seedling placement tray of the integrated machine for transplanting through a slit under the film to carry out the operation of transplanting small tobacco seedlings through a slit under the film.

[0076] First, do a good job in equipment preparation. Firmly install the bracket 1 on the vehicle body 8, carefully check the connection status of each component to ensure firmness without looseness. Debug equipment such as the electric push rod and the first cylinder 204 to ensure its normal operation, and debug the data transmission between the controller and the vision sensor to make the whole system in a working state.

[0077] Then, the vehicle body 8 is moved in the smoke pit to start the film opening operation, and the first electric push rod 302 is started, and its telescopic rod immediately drives the movable end of the linear track 303 to move, and then pushes the fixed block 304 to drive the opening piece 308 to move toward the top of the black film. In this process, the gas spring 309 takes the lead in playing a role, so that the pressure plate 3091 presses the black film, and then the opening piece 308 continues to move downward under the continuous drive of the fixed block 304, and its sharp lower end is smoothly inserted into the black film. Then, the second electric push rod 305 is started, and its telescopic rod drives the straight groove rod 306 to move, and the straight groove rod 306 drives the swing rod 307 to swing through the convex shaft, and finally the opening piece 308 swings, and the black film is accurately opened. After the film opening is completed, the seedling tray containing the flue-cured tobacco seedlings is placed in the seedling tray placement groove 103 of the feed channel 102, and the flue-cured tobacco seedlings are manually placed in the feed channel 102. The flue-cured tobacco seedlings will naturally slide down the slope surface of the feed channel 102 to the seedling guide platform 406. At this time, the first cylinder 204 in the driving member 2 is started, and its piston rod drives the connecting shaft 203 to move, and the connecting shaft 203 drives the circular shaft 4021 to move. The circular shaft 4021 moves in the fixed track 401 and drives the first limit plate 402 to move, and the first limit plate 402 then drives the second limit plate 403 to move. The bottom of the second limiting plate 403 is slightly tilted downward, and its unique arc structure plays a good guiding and limiting role for the flue-cured tobacco seedlings, effectively preventing the flue-cured tobacco seedlings from falling. During the movement of the first limiting plate 402, the connecting rod 4041 is driven to swing, and the connecting rod 4041 drives the soil-digging plate 404 to swing downward. When swinging downward, the soil-digging plate 404 inserts into the soil and digs the soil away, creating a suitable space for the flue-cured tobacco seedlings to fall into. At the same time, the swinging of the soil-digging plate 404 drives the rotating shaft 405 to rotate, and the rotating shaft 405 drives the outer end of the seedling guide plate 4051 to swing in the direction of lifting upward. Under the guiding action of the seedling guide plate 4051 of the seedling guide platform 406, the flue-cured tobacco seedlings on the guide plate 4010 move with the guide plate 4010. As the seedling guide plate 4051 is lifted, the tobacco seedlings slide down and move along the channel between the lower side of the auxiliary transmission shaft 4023 and the soil-pushing plate 404. The auxiliary transmission shaft 4023 rotates when the tobacco seedlings move to assist their smooth movement. Finally, the tobacco seedlings slide down along the soil-pushing plate 404 and enter the soil pit opened by the soil-pushing plate 404, completing the seedling dropping process.

[0078] During the entire transplanting process, when the visual sensor on the upper side of the seedling baffle 501 detects that a tobacco seedling has passed, the third electric push rod 502 responds quickly, controlling the seedling baffle 501 to move up to block the lower end of the feed channel 102 to prevent the next tobacco seedling from accidentally entering. After a soil-moving action is performed and the piston rod of the first cylinder 204 drives the second limit plate 403 and the soil-moving plate 404 to return to the initial position, the baffle assembly 5 drives the seedling baffle 501 to move back to its original position for the next seedling-dropping operation.

[0079] The above are only two embodiments of an absorption tube fixing bracket of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included in the patent protection scope of the present invention.
