Description

Technical Field

[0001] The invention relates to the technical field of corn planting, and in particular to a planting method for reducing corn waterlogging damage. Background Art

[0002] Corn, also known as maize, corn, etc., is one of the most important food crops in the world. Corn is edible and has the characteristics of high calorific value. Various pastries made by mixing corn with other foods are delicious. Corn is not only an important food crop, but also known as the "king of feed". It is also the main source of animal feed and is widely used in industry, such as in the production of ethanol fuel and bioplastics.

[0003] Waterlogging is a natural disaster that has a serious impact on global agriculture. Waterlogging not only directly damages the physical structure of crops, but also indirectly affects crop growth by changing soil chemistry and microbial communities, leading to a decrease in crop yield and quality. Especially in the summer corn growing season, due to concentrated precipitation, it is easy to form waterlogging in the fields, causing corn waterlogging. In this case, the oxygen content in the soil decreases sharply, forcing the plant roots to perform anaerobic respiration, which not only limits the normal growth and development of the roots, but also causes toxic effects on the roots due to the accumulation of anaerobic respiration products. At the same time, the reducing Substances such as H2S and FeS will also accumulate with the increase of anaerobic conditions, further deteriorating the rhizosphere environment and inhibiting the absorption of mineral ions and other beneficial trace elements. In addition, when the soil is flooded, nitrates tend to migrate downward with the water, exceeding the range that the roots can effectively absorb, resulting in serious fertilizer loss and reducing the concentration of available mineral nitrogen in the soil, thereby affecting the nitrogen absorption efficiency of crops. In the long run, this will seriously affect the accumulation of nitrogen during the crop growth cycle, which will ultimately be reflected in the nitrogen content of grains or other economic organs, directly affecting the yield and quality of crops.

[0004] In the traditional corn planting process, the traditional flat planting mode is adopted. The roots of corn plants are easily exposed to ground moisture, which increases the possibility of waterlogging. It is usually necessary to carry out multiple processes such as drip irrigation pipe burial, ridge opening, film covering and sowing separately. Each process often relies on different mechanical equipment, which not only increases the complexity and time cost of the operation, but also aggravates the problem of soil compaction due to the multiple round trips of the machinery, affecting the development of the crop root system and the overall growth environment. Therefore, it is necessary to design a planting method that is practical and efficient to reduce corn waterlogging damage. Summary of the invention

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) The high ridge double-row planting mode of the present application combined with an effective drainage channel can effectively reduce the risk of roots being immersed in water for a long time, reducing root rot and other related diseases caused by waterlogging. A healthy root system is the basis for ensuring the normal absorption of water and nutrients by crops, which is directly related to the final yield. Deep plowing breaks the plow bottom layer, increases soil permeability, promotes root development, and enhances the resistance of corn plants to water stress. Especially in conditions prone to waterlogging, a good drainage system can help maintain appropriate soil moisture without causing waterlogging problems, thereby reducing the negative impact of waterlogging. (2) Components such as pipe burying parts, filling parts, ridge opening parts, film covering parts, soil digging parts and sowing parts are integrated on the same machine, which simplifies multiple steps of traditional agricultural production, reduces the operating difficulty and technical threshold for farmers, greatly improves the ease of operation and maintenance of the equipment, reduces the land compaction problem caused by multiple mechanical operations, and improves work efficiency. The one-time operation mode significantly reduces the repeated rolling of the land by the machine, improves the work efficiency of the entire planting process, and allows more farmland area to be processed per unit time, protects the soil structure, and promotes root growth. At the same time, the various components work together to achieve seamless connection from drip irrigation pipe laying to sowing, greatly reducing the need for manual intervention; (3) The design of the suspension frame allows the entire device to be easily connected to a tractor or other power source, making it easy to move and operate. More importantly, by adjusting the mechanical structure on the suspension frame, the distance between the two rows can be easily changed to adapt to different planting specifications or requirements of specific areas. This flexibility makes the device suitable for a variety of farmland environments, especially in areas prone to waterlogging, and the planting layout can be optimized according to actual conditions; (4) With the joint action of the buried pipe parts, filling parts, ridge opening parts, film covering parts, soil digging parts and sowing parts, a high ridge double-row planting pattern can be formed, and double-row corn seeds can be sown at the same time. This pattern helps to improve the field microclimate, increase light intensity, facilitate ventilation and light transmission, and reduce the occurrence of pests and diseases. At the same time, it can also effectively prevent rainwater accumulation and avoid root rot caused by excessive water. In addition, high ridges can provide better drainage performance, ensuring that the soil will not be too wet during the rainy season and maintain a suitable humidity level. Compared with traditional single-row planting, the double-row layout increases the gaps between crops, which is conducive to air circulation and sunlight exposure, reducing the probability of pests and diseases. Good light conditions can also improve photosynthesis efficiency and further promote the increase of crop yields; (5) The irrigation system is optimized through buried pipe fittings, filling fittings, ridge opening fittings and other components, and they are all on the same path. The buried pipe fittings are responsible for accurately burying the drip irrigation pipe in the soil at a set depth and are placed in the center between two ridges. This arrangement ensures that water and fertilizer resources can be evenly distributed to the corn plants on both sides, avoiding the problem of local over-wetting or drought, and improving the utilization rate of water resources. As an efficient water-saving irrigation technology, the drip irrigation system can meet the needs of corn at different growth stages by accurately controlling the water flow rate and time. The application of film covering further reduces water evaporation losses and ensures the effective absorption of nutrients. (6) Although buried pipe fittings, filling parts and other components are integrated into an overall system, each part is still an independent functional unit. They can be inspected and maintained separately as needed. When a component has a problem, it is only necessary to deactivate the component and repair or replace it without disassembling the entire equipment. This not only saves maintenance time and costs, but also extends the service life of the entire system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-12 The present invention provides a technical solution: a planting method for reducing corn waterlogging damage, comprising the following steps: S1. Construction of drainage channels: According to the terrain and farmland layout, the drainage system should be reasonably planned to ensure that it can quickly and effectively drain away excess precipitation. Regular maintenance should be carried out to ensure that the drainage ditches are unobstructed and avoid silt or weed blockage. A good drainage system is conducive to reducing the impact of waterlogging on corn; S2, land preparation S21, deep tillage: Deep tillage is set at about 25-30 cm, which can effectively break up the plow bottom layer and improve soil permeability. Precisely laying the drip irrigation system is very critical to achieving water-saving irrigation, especially in conditions prone to waterlogging. It can help maintain proper soil moisture without causing waterlogging problems; S22, Fertilization: Based on the soil test results, formulate a scientific and reasonable fertilization plan, focusing on the ratio of nitrogen, phosphorus and potassium, as well as the supplementation of medium and trace elements. The use of slow-release fertilizers can continuously provide nutrients for a longer period of time and reduce nutrient loss caused by excessive water; S3, seed treatment: First, place the corn seeds in the sun for 3 to 4 hours to help activate the vitality of the seeds. Prepare a special seed soaking solution, which is a mixture of garlic juice, ethanol and water in a ratio of 7:1.5:5. Stir well and put the dried seeds into the above prepared solution and soak for 24 to 48 hours. This can help the seeds resist certain diseases and promote germination. After soaking, take out the seeds and continue to soak them in warm water at a temperature of 50 to 56 degrees Celsius for 10 minutes. This step can further stimulate seed germination and eliminate possible pathogens. Finally, rinse the seeds with clean water 3 times to ensure that the residual seed soaking solution and other impurities are removed; S4, formal planting S41, Drip irrigation pipe burial: The drip irrigation pipe is arranged along the planting row through the corn planting device, and buried 5-10 cm from the ground surface. This can not only protect the pipe from damage by mechanical operations, but also facilitate installation and maintenance. The precisely laid drip irrigation system is conducive to water-saving irrigation. In the case of waterlogging, it can help maintain appropriate soil moisture without causing water accumulation problems; S42, ridge opening: After the buried pipes are laid, ridge opening is performed using a corn planting device, and high ridge double-row planting is adopted. High ridge double-row planting is not only conducive to drainage, but also improves ventilation conditions and reduces the occurrence of diseases. The high ridge design makes the soil surface more loose and breathable, which is conducive to root respiration and water evaporation, thereby reducing the negative impact of waterlogging; S43, Film covering: Use breathable or degradable film to maintain soil moisture and protect the environment. Film covering can help reduce soil moisture evaporation. Film covering with corn planting device can maintain stable soil temperature, inhibit weed growth, and help prevent soil compaction. Film covering can also help stabilize soil temperature and create good conditions for seed germination. S44, sowing: sowing the processed corn seeds by a corn planting device; Specifically, the corn planting device includes a suspension frame 1 and a body 2, wherein the suspension frame 1 is arranged on one side of the body 2 for connecting with the driving end, and the body 2 includes a wing seat 21 and a connecting piece 22, wherein the wing seat 21 is arranged in a mirror-symmetrical manner and is fixedly connected in the middle by the connecting piece 22, and a placement area 211 is provided at the far end of the wing seat 21, and a roller 212 is movably installed in the placement area 211 and a limit plate 213 is threadedly connected to the end of the roller 212 for placing and limiting the drip irrigation pipe, and a buried pipe part 3, a filling part 4, a ridge-opening part 5, a film-covering part 6, a soil-moving part 7 and a sowing part 8 are arranged on the body 2 in sequence, and the sowing part 8 and the suspension frame 1 are respectively located on both sides of the body 2, and a moving wheel 9 is symmetrically provided at the lower end of the wing seat 21, and the moving wheel 9 is distributed in a rectangular shape at the lower end of the body 2; The main structure of the present application is composed of a suspension frame 1, a body 2 and a moving wheel 9. The suspension frame 1 is arranged on one side of the body 2, and is used to connect the entire device to a tractor or other driving equipment to ensure its stability and controllability during field operations. This connection method enables the device to be towed or pushed to adapt to the working requirements of different farmlands. The body 2, as the core part of the device, is composed of side wing seats 21 symmetrically distributed on both sides and a connecting piece 22 in the middle, forming a solid overall structure.

The rigidity and stability of the body 2 are ensured by the functional components, which are composed of buried pipe parts 3, filling parts 4, ridging parts 5, film covering parts 6, soil excavating parts 7 and sowing parts 8. The placement area 211 is located at the end of the side wing seat 21 away from the suspension frame 1. A roller 212 is movably installed inside to carry and guide the drip irrigation pipe. The end of the roller 212 is threadedly connected to a limit plate 213. The function of the limit plate 213 is to ensure that the position of the drip irrigation pipe is fixed during transportation to prevent it from shifting or falling off. This design ensures that the drip irrigation pipe can be laid smoothly and accurately to the predetermined position. The buried pipe part 3 is responsible for accurately placing the drip irrigation pipe The filling and leveling parts 4 are accurately buried in the soil at a set depth (5-10 cm) to protect the pipes from external damage and ensure the normal operation of the irrigation system. After the drip irrigation pipes are buried, the filling and leveling parts 4 are used to backfill and level the grooves to prepare for the subsequent steps. This step helps to maintain the flatness of the soil surface and facilitates the subsequent ridge opening and film covering work. According to the requirements of high ridge double-row planting, the ridge opening parts 5 can create an ideal ridge shape suitable for corn growth, improve drainage conditions and ventilation environment. High ridge double-row planting is not only conducive to drainage, but also improves ventilation conditions and reduces the occurrence of diseases. The film covering part 6 uses a breathable or degradable film to cover the ridge surface, keep the soil moisture and temperature stable, inhibit the growth of weeds, and prevent soil compaction. The film covering can help reduce soil moisture evaporation, maintain soil temperature stability, inhibit weed growth, and help prevent soil compaction. The soil shifting part 7 works with the film covering part 6 to gently move the soil during the film covering process to ensure that the film is close to the ground and enhance the heat preservation and moisture retention effect. The sowing part 8 is the last link. The sowing part 8 accurately sows the pre-treated corn seeds on the ridge surface to provide a good start for crop growth; The components of the present application, such as the buried pipe component 3, the filling component 4, the ridge opening component 5, the film covering component 6, the soil excavating component 7 and the sowing component 8, are integrated on the same machine, which reduces the land compaction problem caused by multiple mechanical operations and improves work efficiency. The one-time operation mode significantly reduces the repeated rolling of the land by the machine, protects the soil structure, and promotes the growth of the root system. At the same time, the components work together to achieve a seamless connection from the laying of the drip irrigation pipe to the sowing, which greatly reduces the need for manual intervention.

The main task of the furrowing plow 35 is to open a suitable furrow in the field to facilitate the subsequent laying of irrigation pipes. After the drip irrigation pipe passes through the conveying path groove 214, the path opening 341, and the arc path groove 371 in sequence, it finally smoothly enters the furrow opened by the furrowing plow 35 to complete the burial of the drip irrigation pipe. The design of the furrowing plow 35 with a width slightly larger than the outer diameter of the drip irrigation pipe ensures that the size of the furrow is moderate, which can accommodate the drip irrigation pipe without being too large, thereby avoiding unnecessary soil disturbance, so that the drip irrigation pipe can be accurately placed in the pre-opened small-scale furrow, which not only improves the laying speed, but also ensures The stability of the drip irrigation system is improved. At the same time, due to the appropriate size of the groove, the subsequent filling and leveling parts 4 can easily complete the backfilling operation, ensuring that the soil surface is flat and does not affect other farming operations. Compared with the traditional large-scale trenching method, the small-scale grooves used in this device reduce the damage to the soil structure and help maintain the original properties of the soil, such as air permeability and water retention capacity. By accurately controlling the groove size, the position of the drip irrigation pipe is more fixed, which helps to achieve a more uniform water supply and avoid local waterlogging or drought caused by pipe position deviation. At the same time, the small-scale groove means that the amount of soil that needs to be moved is reduced, which reduces mechanical energy consumption, and because there is no need to fill a large amount of soil, it also saves time costs; Specifically, the filling member 4 is symmetrically arranged at the lower end of the side wing seat 21, and the soil-moving member 7 is arranged at the lower end of the side wing seat 21. The filling member 4 and the soil-moving member 7 have the same structure and similar functions. The filling member 4 includes a fixing rod 41 and a filling plate 42. The fixing rod 41 is fixedly installed at the lower end of the side wing seat 21 by fastening bolts. The filling plate 42 is fixedly installed at the end of the fixing rod 41. The filling plate 42 is inclined and is made of a rubber plate. The fixing rod 41 is a key component connecting the wing seat 21 and the filling plate 42. The fixing rod 41 provides necessary mechanical support to ensure that the filling plate 42 can remain stable during operation. The fixing rod 41 is fixed to the lower end of the wing seat 21 by fastening bolts, which is convenient for disassembly and maintenance. The filling plate 42 is made of rubber plate and is inclined. The main function of the filling plate 42 is to gradually push the soil on both sides to the center of the groove during movement and perform preliminary leveling treatment on it. The choice of rubber material not only increases the wear resistance and impact resistance of the filling plate 42 The impact performance is also given to it, and a certain elasticity is given to it, so that it can automatically adjust the pressure when it contacts soils of different hardnesses, avoiding excessive compaction of the soil. When the furrowing plow 35 completes the trench excavation, the filling member 4 immediately pushes the surrounding soil back into the trench. The inclined design of the filling plate 42 enables it to more effectively press the soil into the trench to form a relatively compact covering layer. Since the filling plate 42 is arranged in an inclined manner, it can gradually press the soil into the trench during the movement process, forming a compact and breathable covering layer, thereby providing a stable buried environment for the drip irrigation pipe; Specifically, the ridging member 5 includes a lower support rod 51 and a ridging plow 52. The lower support rod 51 is fixedly mounted on the lower end of the side wing seat 21 by bolts, and the ridging plow 52 is fixedly mounted on the end of the lower support rod 51. The ridging plow 52 and the furrowing plow 35 are on the same travel path, and the lower end surface of the ridging plow 52 is higher than the lower end surface of the furrowing plow 35. The ridging plow 52 and the furrowing plow 35 are on the same path, which means that the two can complete the tasks of trench excavation, drip irrigation pipe laying and soil ridging in one process. The furrowing plow 35 first opens a trench of a predetermined depth. During this process, the drip irrigation pipe can be placed synchronously to ensure that it is accurately located in the center between the two ridges of crops. Since the drip irrigation pipe is accurately placed between the two ridges of crops, it can provide a uniform water supply for the corn crops on both sides. This layout allows water and fertilizer resources to be more effectively absorbed by the crops, reduces waste, and improves irrigation efficiency. The lower end surface of the ridging plow 52 is higher than the lower end surface of the furrowing plow 35, and is also higher than the drip irrigation pipe, in order to prevent any possible damage to the drip irrigation pipe during the ridging process; Specifically, the film covering member 6 includes a fixing frame 61, a rotating roller 62 and a ground film 63. The fixing frame 61 is fixedly mounted on the side wall of the wing seat 21 by fastening bolts, the rotating roller 62 is movably mounted between the fixing frames 61 and the ground film 63 is wound around the rotating roller 62. The distance between the two ends of the ground film 63 is smaller than the distance between the furrowing plows 35. The main task of the film covering member 6 is to accurately lay the ground film 63 on the ridge body after completing the furrowing and ridging operations. The ground film covering can effectively reduce water evaporation, inhibit weed growth, and increase soil temperature, thereby creating favorable conditions for crop growth. The film covering member 6 works together with the furrowing plow 35 and the ridging plow 52 on the same travel path, achieving the one-time completion of furrowing, ridging and film covering. This efficient working method not only saves time and labor, but also improves the overall work efficiency. The spacing between the two ends of the ground film 63 is smaller than the spacing between the furrowing plows 35, which means that the width of the ground film 63 is slightly narrower than the distance between the two rows of furrowing plows 35. This design is to ensure that the ground film 63 can fit closely on both sides of the ridge body to avoid the problem of ground film waste or uneven laying caused by excessive width; Specifically, the sowing member 8 includes an adjustment seat 81, a screw plate 82, a rocker arm 83 and a duckbill seeder 84. A clearance area 215 is provided between the side wing seats 21. The adjustment seat 81 is symmetrically arranged in the clearance area 215. The adjustment seat 81 is symmetrically and movably mounted on the connecting rod 221 at the other end. The upper end of the adjustment seat 81 is threadedly connected with a screw shaft and the screw plate 82 is fixedly mounted at the end of the screw shaft. The screw shaft is in contact with the connecting rod 221. The rocker arm 83 is fixedly mounted at the edge of the upper end of the screw plate 82. The duckbill seeder 84 is fixedly mounted on one end of the adjustment seat 81. The main task of the sowing member 8 is to accurately sow the seeds to the predetermined position after completing the furrowing and ridging operations. Through the precision sowing technology, it can ensure that each seed is in an ideal growth environment, thereby improving the germination rate and crop yield. The main task of the screw plate 82 is to change the distance between a pair of duckbill seeders 84 by adjusting its position. This adjustment capability enables the agricultural machinery to adapt to the planting requirements of different crops and ensure that the seeds can be sown within the ideal spacing. The clearance area 215 provides a larger activity range. The screw plate 82 and its related components are symmetrically arranged in the clearance area 215 between the side wing seats 21; Specifically, the measuring member 23 includes an end plate 231, a measuring rod 232 and a limit block 233. The other end of the bidirectional threaded rod 224 passes through the wing seat 21 and is threadedly connected to the end plate 231. The corresponding side wall of the wing seat 21 is provided with a movable groove 216. The end plate 231 is movably installed in the movable groove 216. The edge of the end plate 231 passes through the measuring rod 232 and is movably installed. One end of the measuring rod 232 is fixedly installed in the movable groove 216 and the other end is fixedly installed with the limit block 233. The outer wall surface of the limit block 233 is flush with the outer wall surface of the wing seat 21. The measuring rod 232 is provided with measuring scale lines. The end plate 231 serves as a connecting part. The end plate 231 is threadedly installed on the other end of the bidirectional threaded rod 224 and movably installed in the movable groove 216 opened in the side wall of the wing seat 21. This design allows the end plate 231 to slide along the movable groove 216 as the bidirectional threaded rod 224 rotates, thereby changing its position relative to the wing seat 21. The measuring rod 232 passes through and is movably installed at the edge position of the end plate 231. One end is fixedly installed in the movable groove 216, and the other end is fixedly installed with a limit block 233. The measuring rod 232 is provided with measuring scale lines for intuitively displaying the moving distance of the end plate 231. The design of the measuring scale lines allows the operator to directly read the position information, which is convenient for monitoring and adjustment. The limit block 233 is fixedly installed at one end of the measuring rod 232, and its outer wall surface is flush with the outer wall surface of the wing seat 21. The function of the limit block 233 is not only to mark the measurement end point, but also to prevent the end plate 231 from excessive movement, thereby ensuring the stability of the entire system.

[0020] Working principle: In the preparation stage, install the suspension frame 1 on the tractor or other driving equipment to ensure the stability and controllability of the entire device during field operations, confirm that all functional components such as buried pipe parts 3, filling parts 4, ridge opening parts 5, film covering parts 6, soil-moving parts 7 and sowing parts 8 have been correctly installed and are in good working condition, especially to ensure that the roller 212 and its limit plate 213 in the drip irrigation pipe placement area 211 can operate smoothly, plan a reasonable drainage system according to the specific terrain and layout of the farmland to ensure that it can quickly and effectively remove excess precipitation, regularly clean the drainage ditches to prevent silt or weeds from clogging to maintain the smooth flow of the system, use deep tillage tools to deeply treat the soil, usually set to about 25-30 cm, in order to break the plow bottom layer, improve soil permeability, and promote root development, formulate a scientific and reasonable fertilization plan based on the previous soil test results, focus on the ratio of nitrogen, phosphorus and potassium and the supplement of medium and trace elements, and use slow The released fertilizer can continuously provide nutrients for a long time and reduce the loss of nutrients caused by excessive rainfall. The corn seeds are pre-treated, and the drip irrigation pipes are arranged along the planting rows through the corn planting device and buried at a distance of 5-10 cm from the ground surface. This can not only protect the pipes from damage by mechanical operations, but also facilitate installation and maintenance, ensuring the normal operation of the irrigation system while reducing water evaporation losses. After the buried pipes are buried, the ridge-opening piece 5 is used to create a high ridge double-row planting mode. This method is not only conducive to drainage, but also can improve ventilation conditions and reduce the probability of disease. Use breathable or degradable mulch to cover the opened ridge surface to keep the soil moisture and temperature stable, inhibit weed growth, and help prevent soil compaction. The last step is to sow the treated corn seeds through the corn planting device. The device integrates multiple functional components to achieve a one-time completion from drip irrigation pipe laying to sowing, greatly improving work efficiency and reducing the need for manual intervention.
