Description

Technical Field

[0001] The present invention relates to the field of agricultural technology, and in particular to a film-covered intelligent sowing method for prefabricated seeds on a film. Background Art

[0002] As a major production area in China, Xinjiang's unique geographical environment and climatic conditions have had a profound impact on planting methods. The region's water resources are scarce and the growing season is short, which has led to mulching and hole sowing becoming the main planting method in the area. In the traditional sowing process, after the land is leveled, it is usually operated by a tractor-towed seeder. The specific operation is to first lay the ground irrigation belt and ground film with the seeder, and then complete the preliminary preparations through processes such as film spreading, film pressing, and edge covering. Then, use the sowing wheel to poke holes and sow the seeds into the sowing holes.

[0003] However, this traditional sowing process has many drawbacks. In terms of sowing efficiency, due to the special climate in Xinjiang, the time window for sowing operations is relatively short, and the existing sowing process has a speed of only about 3.5 km / h, which leads to low overall sowing efficiency. In order to ensure that the sowing task is completed within a limited time, it is often necessary to organize more equipment and personnel, which not only increases the manpower and material costs, but also makes personnel organization difficult. For example, in large-scale sowing operations, coordinating the cooperation of different equipment and personnel requires a lot of time and energy. Any carelessness may lead to delays in sowing progress and affect the entire planting cycle.

[0004] In terms of sowing quality, the existing technology also faces severe challenges. On the one hand, due to the limitations of the mechanical structure of the sowing mechanism, its controllability in the field is poor, and missed or over-sowing often occurs. This not only wastes seed resources, but may also affect the uniform growth of cotton seedlings, which in turn has an adverse effect on the final yield. On the other hand, affected by the soil and natural environment, the ground film often moves. This will cause the sowing hole and the seed position to be in sync, resulting in problems such as the seeds being pressed against the ground film and unable to effectively grow out of the ground, or being burned by the lens effect formed by the water droplets intercepted by the ground film. These problems seriously affect the emergence rate, which in turn restricts the yield.

[0005] In addition, the drip irrigation tape is an important facility for replenishing water for cotton seedlings, and its optimal placement should be between every two rows. However, under the existing sowing process, due to poor precision, if the drip irrigation tape is placed between two rows of cotton seedlings, the sowing wheel can easily press the drip irrigation tape, causing damage and leakage of the drip irrigation tape. Therefore, in order to avoid this situation, the existing process can only adopt the method of offsetting the drip irrigation tape. However, this method causes the effective penetration shape of the drip irrigation tape to be misaligned with the actual position of the cotton seedlings, resulting in partial waste of water application by the drip irrigation tape. If the drip irrigation tape can be placed in the center of the two rows, although a certain amount of water will be saved, due to the mechanical structure of the sowing mechanism, it is difficult to achieve precise control in the field, which affects the overall irrigation effect and growth. The existing film-covered sowing process has many shortcomings in terms of efficiency, quality and resource utilization. There is an urgent need for a new intelligent sowing method to overcome these problems and improve the efficiency and quality of planting. Summary of the invention

[0006] In view of this, the present invention aims at the deficiencies of the prior art and proposes a film-covered intelligent sowing method for prefabricated seeds on a film, aiming to solve at least one of the problems raised by the above-mentioned background technology.

[0007] The present invention provides a film-covered intelligent sowing method for prefabricated seeds on a film, comprising the following steps:

[0008] S1. Sterilize water-sensitive paper;

[0009] S2, drying the ground film and the water-sensitive paper after sterilization;

[0010] S3, a plurality of planting holes are opened on the ground film, and the top and bottom of each planting hole are sealed and connected with the water-sensitive paper, and the seeds to be planted are placed between two water-sensitive papers;

[0011] S4, setting a drip irrigation belt between two adjacent planting holes, wherein the distance between the drip irrigation belt and the two adjacent planting holes is the same;

[0012] S5, attaching a protective film to the surface of the ground film and rolling up the ground film, and laying the rolled-up ground film on the land to be planted by a ground film machine.

[0013] In some embodiments, the step S1 of sterilizing the water-sensitive paper includes irradiating the water-sensitive paper with an ultraviolet sterilization lamp, the distance between the ultraviolet sterilization lamp and the water-sensitive paper is 40-50 cm, and the ultraviolet sterilization lamp irradiates for 25-30 minutes.

[0014] In some embodiments, before the water-sensitive paper is sterilized by ultraviolet light, the damaged water-sensitive paper needs to be removed.

[0015] In some embodiments, the step S2 of drying the ground film includes: adjusting the blowing temperature of the hot air blower to 40-60° C., and drying the ground film by the hot air blower.

[0016] In some embodiments, the step S2 of drying the water-sensitive paper includes: placing the water-sensitive paper in a drying dish and letting it stand for 3-5 hours.

[0017] In some embodiments, the step S3 of opening a plurality of planting holes in the ground film includes: arranging a plurality of first planting hole groups spaced apart along the length direction of the ground film, the first planting hole groups including a first column of planting holes and a second column of planting holes, the first column of planting holes and the second column of planting holes both including a plurality of the planting holes spaced apart along the width direction of the ground film, and the first column of planting holes and the second column of planting holes are symmetrically arranged.

[0018] In some embodiments, the water-sensitive paper and the ground film in step S3 are connected by heat-pressing sealing.

[0019] In some embodiments, setting a drip irrigation tape between two adjacent planting holes in step S4 includes setting the drip irrigation tape between the first column of planting holes and the second column of planting holes, and the distance between the drip irrigation tape and the first column of planting holes is the same as the distance between the drip irrigation tape and the second column of planting holes.

[0020] In some embodiments, the drip irrigation tape is heat-welded to the ground film.

[0021] In some embodiments, the step S5 of laminating a protective film on the surface of the ground film and rolling up the ground film includes: the protective film is a linear low-density polyethylene film, and the protective film is adhesively connected to the ground film.

[0022] Compared with the prior art, the beneficial effect of the present invention is that each seed can be accurately placed at the set position by opening planting holes on the ground film according to the sowing position and fixing the seeds with soluble water-sensitive paper or water-sensitive non-woven fabric. This precise positioning method avoids the problems of uneven seed distribution and inconsistent sowing depth that may occur in traditional sowing, so that the seeds can germinate under the most suitable environmental conditions. All seeds are under almost the same environmental conditions, including soil moisture, temperature, light, etc., thereby ensuring the uniformity of seedling emergence and laying a solid foundation for subsequent field management and harvest. Water-sensitive paper or water-sensitive non-woven fabric can be dissolved according to the moisture conditions in the soil to provide seeds with just the right moisture conditions. In the early stage of sowing, the seeds are kept at a suitable humidity, which helps the seeds absorb moisture and start the germination process. When the ground film is covered on the land, it can effectively block the loss of soil moisture, keep the temperature and humidity of the soil relatively stable, reduce the adverse effects of external environmental factors on seed germination, and improve the germination rate of seeds. Water-sensitive paper or water-sensitive non-woven fabric will dissolve after completing the task of fixing seeds, and will not hinder the growth of seedling roots. A drip irrigation tape is set between two adjacent planting holes, and the drip irrigation tape can accurately deliver water to the roots of each plant. This precise water supply method ensures that water directly acts on the root system of the plant, avoiding a large amount of water waste in traditional irrigation methods. The drip irrigation tape can be used for timed and quantitative irrigation according to the growth needs of the plant, further improving the utilization efficiency of water resources. After the protective film is attached to the surface of the mulch film, it is rolled up again. This step effectively protects the mulch film from damage during storage and transportation. The protective film can prevent the mulch film from mechanical damage such as friction, scratches, and tears. Maintaining the integrity of the mulch film is crucial to ensuring its performance when used in the field. The intact mulch film can better play the role of heat preservation and moisture retention, and provide stable environmental conditions for seed germination and seedling growth.

[0036] See also Figure 1-5 As shown, according to an embodiment of the present application, a film-covered intelligent sowing method for prefabricated seeds on a film includes the following steps:

[0037] S1, sterilizing the water-sensitive paper 1;

[0038] S2, drying the ground film 2 and the water-sensitive paper 1 after sterilization;

[0039] S3, a plurality of planting holes 3 are opened on the ground film 2, and the top and bottom of each planting hole 3 are sealed and connected with the water-sensitive paper 1, and the seeds 8 to be planted are placed between two water-sensitive papers 1;

[0040] S4, a drip irrigation belt 4 is arranged between two adjacent planting holes 3, and the distance between the drip irrigation belt 4 and the two adjacent planting holes 3 is the same;

[0041] S5, attaching a protective film to the surface of the ground film 2 and rolling up the ground film 2, and laying the rolled-up ground film 2 on the land to be planted by a ground film machine. The ground film machine is a prior art.

[0042] In some specific embodiments, the step S1 of sterilizing the water-sensitive paper 1 includes irradiating the water-sensitive paper 1 with an ultraviolet sterilization lamp, the distance between the ultraviolet sterilization lamp and the water-sensitive paper 1 is 40-50 cm, and the ultraviolet sterilization lamp irradiates for 25-30 minutes. The water-sensitive paper can be replaced with a water-sensitive non-woven fabric.

[0043] Ultraviolet rays mainly destroy the DNA or RNA molecular structure of microorganisms, making them lose their ability to reproduce and survive, thereby achieving the sterilization effect. Within a distance of 40-50cm, ultraviolet rays can be concentrated on the surface and inside of water-sensitive paper. The irradiation time of 25-30 minutes ensures that there is enough ultraviolet dose to comprehensively disinfect all kinds of bacteria, fungi, viruses and other microorganisms that may exist. Once these microorganisms are inactivated, they can effectively prevent them from causing harm to seed germination and seedling growth during subsequent use. When irradiated at a distance of 40-50cm, the intensity of ultraviolet rays is moderate, and the fiber structure of water-sensitive paper will not be seriously damaged due to excessive irradiation. If the distance is too close or the irradiation time is too long, the paper may become brittle and yellow, affecting its physical properties. The time control of 25-30 minutes is also relatively reasonable, which not only ensures the sterilization effect, but also avoids unnecessary damage to the paper due to long-term strong ultraviolet irradiation, thereby maintaining the integrity of water-sensitive paper and ensuring that it can normally perform the functions of fixing seeds and dissolving and releasing in subsequent use. A certain amount of heat will be generated during the UV irradiation process, but under the above distance and time conditions, the heat generated will not be too high to have a significant impact on the chemical properties of the water-sensitive paper. For example, it will not denature the glue component in the paper, thus ensuring the stability of the water-sensitive paper before use.

[0044] It is understandable that ultraviolet sterilization is a common and effective physical sterilization method. The key is that ultraviolet rays (especially the UVC band, with a wavelength range of 200-280 nanometers) have a strong bactericidal ability. When ultraviolet rays are irradiated to microorganisms, they can be absorbed by the nucleic acids (DNA or RNA) in the microbial cells. The energy of ultraviolet rays will destroy the chemical bonds in the nucleic acid molecules, causing changes such as distortion and breakage of the nucleic acid molecular structure, which will make it impossible for the microorganisms to carry out key life activities such as replication, transcription and translation normally, and eventually lose their reproduction and survival ability, achieving the purpose of sterilization. Controlling the distance between the ultraviolet sterilization lamp and the water-sensitive paper (or water-sensitive non-woven fabric) at 40-50cm is a comprehensive consideration based on the ultraviolet propagation characteristics and the bactericidal effect. Within this distance range, ultraviolet rays can be irradiated to the surface and inside of the water-sensitive paper in a relatively concentrated manner. On the one hand, it ensures that there is enough ultraviolet intensity to reach the area that needs to be sterilized; on the other hand, it avoids excessive damage to the water-sensitive paper due to excessive ultraviolet intensity caused by too close a distance. If the distance is too close and the ultraviolet energy is too high, the fiber structure of the water-sensitive paper may be seriously damaged, such as making the paper brittle and yellow, affecting its physical properties. The distance of 40-50cm can not only ensure the sterilization effect, but also maintain the integrity of the water-sensitive paper, so that it can normally play the function of fixing seeds and dissolving and releasing in subsequent use. The irradiation time of 25-30 minutes is set to ensure that sufficient ultraviolet doses are provided to comprehensively disinfect all kinds of bacteria, fungi, viruses and other microorganisms that may exist. Different types of microorganisms have different sensitivities to ultraviolet rays, and some microorganisms may require a longer period of irradiation to be effectively killed. The time control of 25-30 minutes is more reasonable, which not only ensures the sterilization effect, but also avoids unnecessary damage to the paper due to long-term strong ultraviolet irradiation. In practical applications, the heat generated by ultraviolet irradiation within this time range will not be too high, and it is not enough to have a significant effect on the chemical properties of water-sensitive paper, such as not denaturing the glue component in the paper, thereby further ensuring the stability of the water-sensitive paper before use.

[0045] If there is a lot of water after sterilization, on the one hand, it may affect its physical properties, such as reducing strength and toughness, making it easy to break in subsequent operations; on the other hand, too much water may change its chemical properties and affect its function as a carrier for fixing seeds and dissolving and releasing. Through drying treatment, excess water can be removed to keep the water-sensitive paper (or water-sensitive non-woven fabric) in the best use state. Similarly, excessive water in the ground film will cause it to stick and be difficult to unfold during the laying process, affecting the flatness and efficiency of the laying. In addition, a humid environment is also conducive to the growth of microorganisms. Even after the previous sterilization treatment, the residual water may become a hotbed for microorganisms to reproduce again. Therefore, drying the ground film can ensure that it has good performance during use and provide a dry and hygienic growth environment for seeds. Opening multiple planting holes on the ground film is to provide an independent and suitable growth space for seeds. The top and bottom of each planting hole are sealed with water-sensitive paper (or water-sensitive non-woven fabric). This design has many advantages. First, it can prevent seeds from moving or losing after sowing, ensure that seeds are accurately placed in the predetermined position, and improve the accuracy of sowing. Secondly, water-sensitive paper (or water-sensitive non-woven fabric) forms a relatively closed microenvironment around the seeds, which helps to maintain stable humidity and temperature around the seeds and create favorable conditions for seed germination. Water-sensitive paper (or water-sensitive non-woven fabric) has special physical and chemical properties. In a dry state, it can maintain a certain shape and strength, and play a role in fixing seeds; when it comes into contact with water, it will gradually dissolve and release the fixed seeds. This characteristic enables the seeds to remain positioned in a stable environment in the early stages of sowing, waiting for the right moisture conditions to trigger the germination mechanism. At the same time, the dissolution process of water-sensitive paper (or water-sensitive non-woven fabric) is relatively slow and uniform, which can prevent the seeds from being shocked by sudden exposure to a large amount of water, and is conducive to uniform water absorption and germination of seeds.

[0046] Seeds have a more delicate demand for water during the germination and seedling growth stages. Traditional irrigation methods often make it difficult to accurately control the water supply to each planting point, which can easily lead to excessive or insufficient water in some areas. By setting up drip irrigation belts, water can be accurately delivered to the vicinity of each planting hole according to the different stages of growth and actual needs, providing appropriate and uniform water for seed germination and seedling growth. Setting the distance between the drip irrigation belt and two adjacent planting holes to be the same can ensure a more even distribution of water around each planting hole. This can avoid the problem of uneven water supply caused by distance differences, so that each seed can germinate and grow under similar water conditions, which is conducive to improving the overall germination rate and consistency of seedling growth.

[0047] There are two main functions of attaching a protective film to the surface of the ground film. One is to prevent external impurities from entering the ground film to avoid damage to seeds and seedlings; the other is to reduce water loss and keep the humidity environment inside the ground film relatively stable. After sowing, especially in the early stages of seed germination and seedling growth, a stable humidity environment is crucial for seed germination and seedling growth. The protective film can prevent water evaporation to a certain extent and provide a relatively humid microclimate environment for seeds and seedlings.

[0048] There are many advantages to using a mulching machine for laying mulch. First, the mulching machine can achieve efficient and rapid mulch laying operations, greatly improving sowing efficiency and saving manpower and time costs. Secondly, the mulching machine can make the mulch more flat and fit tightly to the land, reducing the gap between the mulch and the land, which is conducive to the mulch's thermal insulation and moisture retention properties. At the same time, the standardized operation of the mulching machine can ensure the quality stability of the mulch laying and provide good basic conditions for the growth of mulch.

[0049] In some specific embodiments, before the water-sensitive paper 1 is sterilized by ultraviolet light, the damaged water-sensitive paper 1 needs to be removed.

[0050] When water-sensitive paper is damaged, its internal fiber structure is exposed. These damaged parts are like tiny "dirt and dirt" places, providing opportunities for microorganisms to take advantage. Microorganisms such as bacteria, fungi and viruses can easily attach to the fibers at the damaged parts and multiply in large numbers in a relatively closed and suitable environment. Once these damaged water-sensitive papers are treated with ultraviolet disinfection, although ultraviolet rays can kill some microorganisms on the surface, microorganisms inside the damaged parts may survive due to insufficient ultraviolet penetration. In the subsequent use process, these surviving microorganisms will pose a serious threat to seed germination and seedling growth.

[0051] In some specific embodiments, the step S2 of drying the ground film includes: adjusting the blowing temperature of the hot air blower to 40-60° C., and drying the ground film 2 by the hot air blower.

[0052] In some specific embodiments, the step S2 of drying the water-sensitive paper includes: placing the water-sensitive paper 1 in a drying dish and leaving it to stand for 3-5 hours.

[0053] It should be understood that adjusting the blowing temperature of the hot air blower to 40-60℃ to dry the ground film is based on the principle of heat transfer and water evaporation. When the hot air generated by the hot air blower contacts the surface of the ground film, the heat will be transferred from the hot air to the ground film. Since the ground film usually contains a certain amount of moisture, after absorbing heat, the molecular movement of these moisture intensifies, and sufficient energy is obtained to overcome the attraction between molecules, so that it gradually changes from liquid to gas, and then detaches from the ground film to achieve the purpose of drying. There are specific considerations for choosing a blowing temperature of 40-60℃. This temperature range can provide enough heat to effectively evaporate the moisture in the ground film, and will not damage the ground film due to excessively high temperature. If the temperature is too low, the evaporation rate of moisture is too slow, the drying efficiency is low, and the ideal drying effect cannot be achieved; and if the temperature is too high, the physical properties of the ground film may change, such as deformation, melting, etc., affecting its subsequent performance. In the intelligent sowing method of mulching, the ground film needs to be kept dry to ensure its performance and function during use. During the laying process, wet mulch is prone to adhesion and difficulty in unfolding, which affects the flatness and efficiency of laying. In addition, the moisture on the mulch may cause excessive local soil humidity after sowing, affecting the respiration and germination conditions of the seeds. By adjusting the air temperature of the hot air blower to 40-60℃ for drying, the moisture in the mulch can be quickly and effectively removed, making it in the best use state and providing a good foundation for subsequent sowing operations.

[0054] Placing the water-sensitive paper in a drying dish and leaving it to stand for 3-5 hours for drying is a process that utilizes the water absorption and natural evaporation of the dry environment. The drying dish usually has a low humidity environment and can absorb moisture from the surrounding air. When the water-sensitive paper is placed in the drying dish, the moisture on the surface of the water-sensitive paper will gradually diffuse into the drying dish under the action of the humidity difference. At the same time, in a static state, the moisture on the surface of the water-sensitive paper will also be lost to the surrounding environment by natural evaporation. This natural evaporation is a relatively slow but stable process, which depends on the vapor pressure of the moisture on the surface of the water-sensitive paper and the relative humidity difference of the surrounding environment. In a low humidity environment such as a drying dish, the moisture on the surface of the water-sensitive paper is more likely to evaporate, thereby achieving the purpose of drying. For water-sensitive paper that has been sterilized, drying is also crucial. If the water-sensitive paper contains too much moisture, on the one hand, it will affect its physical properties, such as reducing strength and toughness, making it easy to break in subsequent operations; on the other hand, too much moisture may change its chemical properties and affect its function as a carrier for fixing seeds and dissolving and releasing. For example, moisture may interfere with the interaction between the water-sensitive paper and the seeds, resulting in loose seed fixation or affected dissolving and releasing processes. By placing the water-sensitive paper in a drying dish and leaving it for 3-5 hours, the water-sensitive paper can gradually lose excess moisture and maintain its good physical and chemical properties so that it can function normally in the subsequent sowing process and provide a stable growth environment for seeds.

[0055] In some specific embodiments, the step S3 of opening a plurality of planting holes 3 on the ground film 2 includes: arranging a plurality of first planting hole groups 5 spaced apart along the length direction of the ground film 2, the first planting control group 5 including a first column of planting holes 6 and a second column of planting holes 7, the first column of planting holes 6 and the second column of planting holes 7 both including a plurality of the planting holes 3 spaced apart along the width direction of the ground film 2, and the first column of planting holes 6 and the second column of planting holes 7 are symmetrically arranged.

[0056] The spacing and length between the multiple first planting hole groups 5 are determined according to the actual planting environment. The root system of the crop needs enough space in the soil to grow and expand. Determining the length of the first planting hole group 5 according to the root characteristics of the crop can provide a suitable growth environment for the root system. If the length of the planting hole is too short, it will limit the growth of the root system, affect the crop's absorption of water and nutrients, and thus reduce yield and quality. Reasonable setting of the length of the planting hole can ensure that the crop root system can grow healthily and improve the growth potential of the crop.

[0057] Appropriate spacing and length settings can be used as an auxiliary means of pest control. For example, for some infectious pests and diseases, reasonable spacing between planting hole groups can reduce the spread of pathogens.

[0058] By reasonably determining the parameters of the planting hole group, the number of plantings per unit area can be maximized while ensuring the quality of crop growth, thereby improving the efficiency of land use. For example, in fertile soil, the spacing between the planting hole groups can be appropriately reduced to increase the planting density.

[0059] It should be understood that in step S3, when a plurality of planting holes 3 are opened in the ground film 2, a plurality of first planting hole groups 5 are arranged in an interval arrangement along the length direction of the ground film. This design mainly takes into full consideration the growth and expansion requirements of the crop root system in the soil. The crop root system needs to have enough space to extend and distribute in the soil so as to better absorb water, nutrients and respire. By setting up a planting hole group, a relatively independent and suitable growth space can be provided for each seed, which is conducive to the development and growth of the root system in the soil. The first planting hole group 5 includes a first row of planting holes 6 and a second row of planting holes 7, and the two are symmetrically arranged. This symmetrical design is not arbitrary, but is based on the biological characteristics of crop growth. The symmetrical planting hole layout helps to ensure that the seeds are evenly supplied with light, water and nutrients during germination and growth. When irrigation or precipitation occurs, water can penetrate more evenly into the soil around the symmetrically distributed planting holes, reducing the situation where some roots are dehydrated or overabsorbed due to uneven water distribution, and creating a relatively stable growth environment for the crop root system.

[0060] The spacing between the multiple first planting hole groups 5 is determined according to the actual planting environment, which is mainly to provide sufficient growth and expansion space for the crop root system. The root systems of different crops have different growth habits and extension ranges. The root systems of some crops are relatively developed and require a larger space to grow; while the root systems of other crops are relatively shallow and compact. In a fertile soil environment, the nutrient and water content in the soil is high, and the crop root system can relatively easily obtain the required resources from the soil. At this time, the spacing between the planting hole groups can be appropriately reduced to increase the planting density. However, in poor or compact soil, the crop root system needs a larger range to find nutrients and water, so the spacing between the planting hole groups should be increased accordingly to ensure that each crop has enough space to develop its root system. The length of the planting hole group is determined according to the root characteristics of the crop. The appropriate planting hole length is crucial to the growth of the crop root system. If the length of the planting hole is too short, the growth space of the root system will be severely limited, so that the root system cannot fully extend. This will cause the crop root system to be unable to effectively absorb water and nutrients from the soil, thereby affecting the growth and development of the aboveground part, and ultimately reducing yield and quality. For example, some deep-rooted crops with well-developed root systems, such as pineapple and soybean, require longer planting holes to accommodate the growth of their taproots. Reasonable setting of the length of the planting holes can ensure that the crop roots have sufficient depth and breadth in the soil to grow and expand, thereby providing a solid foundation for the growth of crops and improving the growth potential of crops.

[0061] Appropriate spacing and length settings can be used as an auxiliary means of pest control. In agricultural production, pests and diseases are one of the important factors affecting crop growth and yield. Some pests and diseases are contagious and easily spread between crops. When the spacing between planting hole groups is reasonable, it can increase air circulation and light conditions between crops, reduce humidity, and create an environment that is not conducive to the growth and spread of pathogens. At the same time, a reasonable planting hole layout can form a natural isolation zone between crop groups, reducing the path and speed of pathogen transmission. For example, for some foliar diseases, a larger spacing between planting hole groups can make it more difficult for pathogens to spread to adjacent crops through air flow or contact, thereby effectively controlling the occurrence and spread of pests and diseases.

[0062] By reasonably determining the parameters of the planting hole group, the number of crops planted per unit area can be maximized while ensuring the quality of crop growth, thereby improving land utilization efficiency. In agricultural production, land resources are limited, and how to make full use of every inch of land is the key to improving agricultural output and benefits. Reasonable planting hole design can accurately arrange the growth position and spacing of each crop according to the growth needs and soil conditions of different crops, avoiding the over-crowding or over-sparseness that may occur in traditional planting methods. Over-dense planting will cause competition for nutrients, water and light between crops, affecting growth and development; while over-sparse planting will cause a waste of land resources. By optimizing the design of the planting hole group, more crops can be planted on a limited land area, while ensuring that each crop has sufficient growth space and resources, thereby maximizing land utilization efficiency.

[0063] In some specific embodiments, in step S3, the water-sensitive paper 1 and the ground film 2 are connected by heat-pressing sealing.

[0064] In some specific embodiments, setting a drip tape 4 between two adjacent planting holes 3 in step S4 includes setting the drip tape 4 between the first column of planting holes 6 and the second column of planting holes 7, and the distance from the drip tape 4 to the first column of planting holes 6 is the same as the distance from the drip tape 4 to the second column of planting holes 7.

[0065] This arrangement ensures that water can be evenly distributed around each row of planting holes. Since the distances from the drip irrigation belt 4 to the first row of planting holes 6 and the second row of planting holes 7 are equal, the diffusion range and speed of water on both sides are relatively consistent. The amount of water for drip irrigation can be more accurately controlled according to the water demand patterns and growth stages of different crops. By adjusting the water flow rate and irrigation time of the drip irrigation belt 4, the crops can be provided with just the right amount of water. The reasonable arrangement of the drip irrigation belt 4 helps to maintain the appropriate humidity and temperature of the soil. In arid areas or hot seasons, drip irrigation can create a relatively stable soil moisture environment for the roots of crops, buffering the adverse effects of the external environment on crop growth.

[0066] It should be understood that in step S4, the drip irrigation belt 4 is set between the first row of planting holes 6 and the second row of planting holes 7, and the distance from the drip irrigation belt 4 to the first row of planting holes 6 is the same as the distance to the second row of planting holes 7. This setting method is based on the symmetrical design of the planting hole group, which is intended to ensure that the water can be evenly distributed around each row of planting holes. Since the drip irrigation belt 4 is located in the middle of the two rows of planting holes, when the water diffuses to the planting holes on both sides under pressure, its diffusion range and speed are relatively consistent. This is because the diffusion of water droplets in the soil is mainly affected by factors such as soil texture, porosity and water pressure. When the distance between the drip irrigation belt 4 and the two rows of planting holes is equal, the pressure gradient of water in the soil is similar on both sides, so that the water can diffuse to the planting holes on both sides at a relatively uniform speed and range. Just like throwing a stone into a calm lake, the water waves will spread evenly around the stone with the stone as the center. If the stone is not in the center, the diffusion of the water waves will be uneven. Similarly, the central setting of the drip irrigation belt 4 helps to achieve uniform distribution of water.

[0067] According to the water demand and growth stage of different crops, the amount of water for drip irrigation can be more accurately controlled by reasonably setting the position of the drip irrigation belt 4. Different crops have different water requirements at different growth and development stages. For example, in the seedling stage of crops, the root system has not yet fully developed and the water requirement is relatively small; while in the flowering and fruiting stage, the demand for water of crops increases significantly. By setting the drip irrigation belt 4 between two adjacent planting holes 3 and making the distance to the two rows of planting holes the same, the water demand characteristics of crops can be better adapted. In the actual irrigation process, the water flow rate and irrigation time of the drip irrigation belt 4 can be adjusted according to the specific needs of the crops. For example, for crop varieties or growth stages with large water requirements, the water flow rate of the drip irrigation belt 4 can be appropriately increased and the irrigation time can be extended; while for situations with small water requirements, the water flow rate can be reduced or the irrigation time can be shortened. This precise control can provide crops with just the right amount of water, just like tailoring diet plans for different people to meet their needs at different stages.

[0068] The reasonable setting of the drip irrigation belt 4 helps to maintain the appropriate humidity and temperature of the soil. In arid areas or hot seasons, drip irrigation can create a relatively stable soil moisture environment for the roots of crops, buffering the adverse effects of the external environment on crop growth. Under these harsh environmental conditions, the evaporation and loss rate of soil moisture is often fast. If there are no effective irrigation measures, the soil can easily become dry and affect the growth of crops. The drip irrigation belt 4 releases water slowly and continuously, just like covering the soil with a layer of "moisturizing film". When the water on the soil surface evaporates, the water released by the drip irrigation belt 4 can replenish the water in the lower soil in time, so that the soil humidity is kept within a relatively stable range. This buffering mechanism can provide a good moisture environment for the roots of crops, ensuring that crops can still grow normally under drought or hot conditions.

[0069] In addition to maintaining soil moisture, the drip irrigation belt 4 also has a certain regulating effect on soil temperature. In hot weather, the soil surface temperature may rise very quickly, which has an adverse effect on the growth of crops. The water released by the drip irrigation belt 4 absorbs heat during evaporation, thereby reducing the temperature of the soil. This is just like in the hot summer, people feel cool after sprinkling water on the ground. In this way, the drip irrigation belt 4 can create a relatively cool growth environment for the roots of crops and alleviate the damage of high temperature to crops. At the same time, at night or when the temperature is low, the moisture in the soil can play a role in heat preservation, reduce the loss of soil heat, and prevent the soil temperature from being too low. This two-way regulating effect on soil temperature helps to keep the soil temperature relatively stable and provide a suitable temperature condition for the growth of crops.

[0070] In some specific embodiments, the drip irrigation tape 4 is heat-welded to the ground film 2 .

[0071] In some specific embodiments, the step S5 of laminating a protective film on the surface of the ground film 2 and rolling up the ground film 2 includes: the protective film is a linear low-density polyethylene film, and the protective film is bonded to the ground film 2 .

[0072] During the rolling process, the ground film 2 may be subjected to external friction, extrusion and collision. The linear low-density polyethylene film has good flexibility and cushioning properties, which can effectively disperse these external forces and reduce the physical damage to the ground film 2. The ground film 2 may have some special properties, such as heat preservation, moisture retention, and weed prevention. The linear low-density polyethylene film can fit tightly on the surface of the ground film 2 to form a relatively closed environment to prevent external factors from affecting these properties.

[0073] As mentioned above, by opening planting holes on the ground film according to the sowing position and fixing the seeds with soluble water-sensitive paper or water-sensitive non-woven fabric, each seed can be accurately placed at the set position. This precise positioning method avoids the problems of uneven seed distribution and inconsistent sowing depth that may occur in traditional sowing, so that the seeds can germinate under the most suitable environmental conditions. All seeds are under almost the same environmental conditions, including soil moisture, temperature, light, etc., thereby ensuring the uniformity of seedling emergence and laying a solid foundation for subsequent field management and harvest. Water-sensitive paper or water-sensitive non-woven fabric can dissolve according to the moisture conditions in the soil to provide seeds with just the right moisture conditions. In the early stage of sowing, the seeds are kept at a suitable humidity, which helps the seeds absorb moisture and start the germination process. When the ground film is covered on the land, it can effectively block the loss of soil moisture, keep the temperature and humidity of the soil relatively stable, reduce the adverse effects of external environmental factors on seed germination, and improve the germination rate of seeds. The water-sensitive paper or water-sensitive non-woven fabric will dissolve after completing the task of fixing the seeds, and will not hinder the growth of the seedling root system. A drip irrigation belt is set between two adjacent planting holes, which can accurately deliver water to the roots of each plant. This precise water supply method ensures that water directly acts on the root system of the plant, avoiding a large amount of water waste in traditional irrigation methods. The drip irrigation belt can irrigate regularly and quantitatively according to the growth needs of the plant, further improving the utilization efficiency of water resources. The protective film is attached to the surface of the mulch film before rolling it up. This step effectively protects the mulch film from damage during storage and transportation. The protective film can prevent the mulch film from mechanical damage such as friction, scratches, and tears. Maintaining the integrity of the mulch film is crucial to ensure its performance when used in the field. The intact mulch film can better play the role of heat preservation and moisture retention, and provide stable environmental conditions for seed germination and seedling growth.
