Description

Technical Field

[0001] This invention relates to the field of soybean cultivation technology, specifically to a normal distribution soybean planting method and equipment. Background Technology

[0002] Soybeans are an important food crop, oilseed crop, and feed crop in my country. Their yield and quality are directly related to national food security, edible oil supply, and the development of animal husbandry. During soybean cultivation, ecological problems such as heavy clay soil, deep plow pan, slow soil temperature rise, and susceptibility to drought and flooding are common. Therefore, the suitability of soybean cultivation techniques is crucial for increasing yield.

[0003] To address the aforementioned pain points in soybean cultivation, the traditional "three-ridge" cultivation technique has emerged. Its core lies in the integrated application of three key technologies: deep loosening of the ridge, tiered fertilization in the furrow, and precision seeding on the ridge. This technique has demonstrated certain advantages in improving soil temperature, regulating soil moisture, and increasing soil oxygen content, effectively improving the soil environment for soybean growth and becoming one of the mainstream soybean planting models in my country.

[0004] However, with the increasing demand for high-yield and high-quality soybean cultivation, the inherent defects of the traditional "three-row" cultivation technique have gradually become apparent, mainly in the following aspects: First, the sowing layout is unreasonable. Traditional techniques use double-row precision sowing on ridges, with seeds concentrated on the top surface of the ridge. The top layer of soil in this area is easily affected by drought and temperature fluctuations, resulting in unstable seed germination rates. Furthermore, the plants are distributed along the top surface of the ridge, leading to poor ventilation and light penetration, and a tendency for canopy closure in the field, which restricts the improvement of light energy utilization efficiency. Second, the precision of fertilization is insufficient. Although stratified fertilization is adopted, the distribution of fertilizer in the soil layer and its matching with the growth and absorption patterns of soybean roots need to be optimized. Some fertilizer is easily lost or volatilized with water, resulting in low fertilizer utilization and difficulty in fully meeting the nutrient requirements of soybeans at different growth stages. Third, the plant's resistance to adverse conditions is limited. The root system of plants planted on ridges is relatively concentrated in the top layer of soil, making them less adaptable to adverse conditions such as drought and lodging. Moreover, the canopy closure in the field easily induces pests and diseases, further affecting soybean yield and quality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a soybean normal distribution planting method and equipment to solve the defects of traditional "ridge three" cultivation technology, such as unreasonable sowing layout, insufficient fertilization precision, and limited population resistance.

[0006] On the one hand, the present invention provides a method for normal distribution soybean planting, comprising the following steps:

[0007] The ridge preparation step involves preparing the planting plots to form planting ridges with an isosceles trapezoidal cross-section.

[0008] The stratified quantitative fertilization process involves applying lower and upper layers of fertilizer sequentially below the slopes on both sides of the planting ridge.

[0009] The double-row precision sowing step involves sowing soybean seeds on both sides of the planting ridge, above the lower and upper fertilizer layers.

[0010] Furthermore, the soybean seeds are sown at a depth of 4–5 cm below the soil surface.

[0011] Furthermore, the row spacing on the ridges for sowing soybean seeds is 30cm, and the row spacing between ridges is 35cm.

[0012] Furthermore, the upper layer fertilizer is applied 5-7 cm directly below the soybean seeds, and the amount is 1 / 3 of the total fertilizer. The lower layer fertilizer is applied 12-14 cm directly below the soybean seeds, and the amount is 2 / 3 of the total fertilizer.

Each first fertilizer discharge wheel is installed in each first fertilizer discharge port in a corresponding manner.

[0034] The beneficial effects of this invention are reflected in:

[0035] This invention precisely sows soybean seeds on the sloping sides of an isosceles trapezoidal planting ridge, directly above two layers of fertilizer. The relative spatial position of the seeds and the fertilizer layers is fixed and controllable. Firstly, the slope location ensures stable soil moisture, effectively avoiding the adverse effects of surface soil drought and drastic temperature fluctuations on seed germination compared to traditional ridge top planting. This significantly improves seed germination rate and seedling uniformity. Furthermore, slope planting allows the plant roots to be distributed three-dimensionally in the soil, reducing competition between different plants and improving the spatial utilization efficiency of soil nutrients and water. Secondly, with the seeds directly above the fertilizer, the seedling roots can quickly access and absorb the readily available fertilizer during their downward growth, meeting the nutrient needs of the seedlings and preventing nutrient deficiency or weak seedlings, thus laying a solid foundation for high soybean yields.

[0036] This invention involves sequentially placing a lower layer of fertilizer and an upper layer of fertilizer below the slopes on both sides of the planting ridge, with the sowing position directly above the fertilizer. This achieves a synergistic effect of "layered fertilizer application + precise seed positioning." The upper layer of fertilizer is a fast-acting fertilizer, located immediately below the seeds, allowing for rapid absorption by the seedling roots and reducing fertilizer loss. The lower layer of fertilizer is a slow-release fertilizer, situated in the root extension area, providing continuous nutrient supply during critical periods of soybean growth, such as flowering and grain-filling stages, thus matching the nutrient requirements of soybeans at different growth stages.

[0037] The precise sowing location and fertilization layout of this invention work synergistically to develop soybean plant roots, strengthen stems, and significantly enhance lodging resistance. The sloping planting mode improves soil aeration and reduces the probability of root diseases.

[0038] In summary, this invention solves the defects of traditional "ridge three" cultivation technology, such as unreasonable sowing layout, insufficient fertilization precision, and limited population resistance. Attached Figure Description

Detailed Implementation

[0053] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0054] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0055] On the one hand, such as Figure 1 As shown in the figure, this invention provides a soybean normal distribution planting method, which includes the following steps:

[0056] The ridge preparation step involves preparing the planting plot to form planting ridges 110 with an isosceles trapezoidal cross-section, and the ridge spacing of planting ridges 110 is 65cm.

[0057] The stratified and quantitative fertilization process involves applying lower layer fertilizer 120 and upper layer fertilizer 130 sequentially on both sides of the slope below the planting ridge 110.

[0058] The double-row precision sowing procedure on the ridge side involves sowing soybean seeds 140 on both sides of the planting ridge 110, above the lower fertilizer layer 120 and the upper fertilizer layer 130. The sowing depth of soybean seeds 140 is 4-5 cm below the soil surface. The row spacing on the ridge is 30 cm, and the row spacing between ridges is 35 cm.

[0059] In this embodiment, under the premise of keeping the total amount of fertilizer constant, the upper fertilizer 130 is applied 5-7 cm directly below the soybean seeds 140, and the amount is 1 / 3 of the total fertilizer. The lower fertilizer 120 is applied 12-14 cm directly below the soybean seeds 140, and the amount is 2 / 3 of the total fertilizer.

[0060] This invention precisely sows soybean seeds 140 on the sloping sides of an isosceles trapezoidal planting ridge 110, with the sowing position directly above two layers of fertilizer. The relative spatial position of the seeds and the upper and lower fertilizer layers is fixed and controllable. On the one hand, the soil moisture at the sloping location is stable, effectively avoiding the adverse effects of surface soil drought and drastic temperature fluctuations on seed germination compared to traditional ridge top planting, significantly improving seed germination rate and seedling uniformity. Moreover, sloping planting allows the plant roots to be distributed three-dimensionally in the soil, reducing root competition between different plants and improving the spatial utilization efficiency of soil nutrients and water. On the other hand, with the seeds directly above the fertilizer, the seedling roots can quickly contact and absorb the upper layer of fast-acting fertilizer as they grow downwards, meeting the nutrient needs of seedling growth and avoiding nutrient deficiency and weak seedlings, thus laying a solid foundation for high soybean yields.

[0061] This invention involves sequentially placing a lower layer of fertilizer 120 and an upper layer of fertilizer 130 below the slopes on both sides of the planting ridge 110, with the sowing position directly above the fertilizer. This achieves a synergistic effect of "layered fertilizer placement + precise seed positioning." The upper layer of fertilizer 130 is a fast-acting fertilizer, located immediately below the seeds, allowing for rapid absorption by the seedling roots and reducing fertilizer loss. The lower layer of fertilizer 120 is a slow-release fertilizer, situated in the root extension area, providing continuous nutrient supply during critical periods of soybean growth, such as flowering and grain-filling stages, thus matching the nutrient requirements of soybeans at different growth stages.

[0062] The precise sowing location and fertilization layout of this invention work synergistically to develop soybean plant roots, strengthen stems, and significantly enhance lodging resistance. The sloping planting mode improves soil aeration and reduces the probability of root diseases.

[0063] In summary, this invention solves the defects of traditional "ridge three" cultivation technology, such as unreasonable sowing layout, insufficient fertilization precision, and limited population resistance.

[0064] On the other hand, such as Figures 2-12As shown, this embodiment of the invention provides a planting device applied to the above-mentioned soybean normal distribution planting method, including a frame 200, at least one ridging, fertilizing and sowing unit 300, a first fertilizing mechanism 400, a second fertilizing mechanism 500 and a sowing mechanism 600.

[0065] It is understood that the ridging, fertilizing and sowing unit 300 in this embodiment can be set up once, so that ridging, fertilizing and sowing of one planting ridge 110 can be realized at one time. Multiple ridging, fertilizing and sowing units 300 can also be set up side by side, so that ridging, fertilizing and sowing of multiple planting ridges 110 can be realized at one time.

[0066] The front end of the frame 200 is provided with a traction connecting frame 210 for connecting with a traction device, which is an agricultural tractor.

[0067] like Figures 4-6 As shown, the ridging, fertilizing, and sowing unit 300 includes an inverted U-shaped trough 310, two sets of front fertilizing components, two sets of rear fertilizing components, and two sets of sowing components.

[0068] The inverted U-shaped groove 310 extends in the front-to-back direction and is fixed to the lower side of the frame 200. The inverted U-shaped groove 310 is provided with a first scraper 320, a second scraper 330, a third scraper 340 and a fourth scraper 350 in sequence from front to back. The bottom of the first scraper 320, the second scraper 330, the third scraper 340 and the fourth scraper 350 are all formed with scraping grooves that are adapted to the slopes on both sides and the top of the planting ridge 110, respectively.

[0069] Two sets of front fertilizer application components are located between the first scraper 320 and the second scraper 330, and are respectively located on the slopes on both sides of the planting ridge 110. Each front fertilizer application component includes a first V-shaped mudguard 361 and a first fertilizer application pipe 362. The first V-shaped mudguard 361 extends vertically with its convex side facing forward. The upper end of the first V-shaped mudguard 361 is fixed to the top of the inverted U-shaped groove 310. The lower end of the first V-shaped mudguard 361 is inserted into the soil from the slope of the planting ridge 110. The first fertilizer application pipe 362 is located in the concave side of the first V-shaped mudguard 361. The upper end of the first fertilizer application pipe 362 extends out from the top of the inverted U-shaped groove 310.

[0070] Two sets of post-fertilizer application components are located between the second scraper 330 and the third scraper 340, and are respectively located on the slopes on both sides of the planting ridge 110. Each post-fertilizer application component includes a second V-shaped mudguard 371 and a second fertilizer application pipe 372. The second V-shaped mudguard 371 extends vertically with its convex side facing forward. The upper end of the second V-shaped mudguard 371 is fixed to the top of the inverted U-shaped groove 310. The lower end of the second V-shaped mudguard 371 is inserted into the soil from the slope of the planting ridge 110, and the depth of the second V-shaped mudguard 371 inserted into the soil is less than the depth of the first V-shaped mudguard 361 inserted into the soil. The second fertilizer application pipe 372 is located in the concave side of the second V-shaped mudguard 371, and the upper end of the second fertilizer application pipe 372 extends out from the top of the inverted U-shaped groove 310.

[0071] Two sets of seeding components are located between the third scraper 340 and the fourth scraper 350, and are respectively located above the slopes on both sides of the planting ridge 110. Each seeding component includes a third V-shaped mudguard 381 and a seeding tube 382. The third V-shaped mudguard 381 extends vertically with its convex side facing forward. The upper end of the third V-shaped mudguard 381 is fixed to the top of the inverted U-shaped groove 310. The lower end of the third V-shaped mudguard 381 is inserted into the soil from the slope of the planting ridge 110, and the depth of the third V-shaped mudguard 381 inserted into the soil is less than the depth of the second V-shaped mudguard 371 inserted into the soil. The seeding tube 382 is located in the concave side of the third V-shaped mudguard 381, and the upper end of the seeding tube 382 extends out from the top of the inverted U-shaped groove 310.

[0072] In this embodiment, a first scraper 320, a second scraper 330, a third scraper 340, and a fourth scraper 350 are arranged sequentially from front to back in the inverted U-shaped groove 310. When the traction device pulls the planting device forward, the ridge can be shaped by the first scraper 320, the second scraper 330, the third scraper 340, and the fourth scraper 350 in sequence.

[0073] Preferably, the front ends of the two side plates of the inverted U-shaped groove 310 are extended outward, so that the soil in the furrow can be scraped towards the middle of the ridge through the front end of the inverted U-shaped groove 310.

[0074] Preferably, inclined mud guide plates 390 are symmetrically arranged on the front sides of the first scraper 320, the second scraper 330, the third scraper 340 and the fourth scraper 350. The outer edge of the mud guide plate 390 is connected to the side plate on the corresponding side of the inverted U-shaped groove 310, and the lower edge of the mud guide plate 390 is connected to the inclined side on the corresponding side of the scraper groove. In this way, when the first scraper 320, the second scraper 330, the third scraper 340 and the fourth scraper 350 scrape the soil towards the middle to form a ridge, the mud guide plates 390 can guide the soil from both sides of the inverted U-shaped groove 310 towards the middle, avoiding soil accumulation on the front side of each scraper.

[0075] The first fertilization mechanism 400 is used to output fertilizer to the upper end of each first lower fertilizer pipe 362.

[0076] Specifically, refer to Figures 7-9 The first fertilization mechanism 400 includes a first fertilizer hopper 410 and several first fertilizer rollers 420. The first fertilizer hopper 410 is fixedly supported on the frame 200. The bottom of the first fertilizer hopper 410 is provided with several first fertilizer outlets 411. Each first fertilizer roller 420 is installed in each first fertilizer outlet 411 in a corresponding manner. The lower end of each first fertilizer outlet 411 is connected to the upper end of each first lower fertilizer pipe 362 in a corresponding manner through a first fertilizer pipe 430.

[0077] When the first fertilization mechanism 400 is working, the fertilizer in the first fertilizer hopper 410 enters the first fertilizer outlet 411, and is discharged into the first fertilizer pipe 430 through the first fertilizer wheel 420 in the first fertilizer outlet 411. Then, it enters the first lower fertilizer pipe 362 through the first fertilizer pipe 430, so as to output fertilizer to the first lower fertilizer pipe 362.

[0078] The second fertilization mechanism 500 is used to output fertilizer to the upper end of each second lower fertilizer pipe 372.

[0079] Specifically, continue to refer to Figures 7-9 The second fertilization mechanism 500 includes a second fertilizer hopper 510 and several second fertilizer rollers 520. The second fertilizer hopper 510 is fixedly supported on the frame 200. The bottom of the second fertilizer hopper 510 is provided with several second fertilizer outlets 511. Each second fertilizer roller 520 is installed in each second fertilizer outlet. The lower end of each second fertilizer roller 520 is connected to the upper end of each second lower fertilizer pipe 372 through a second fertilizer pipe 530.

[0080] Similarly, when the second fertilization mechanism 500 is working, the fertilizer in the second fertilizer hopper 510 enters the second fertilizer outlet 511, and is discharged into the second fertilizer pipe 530 through the second fertilizer wheel 520 in the second fertilizer outlet 511. Then, it enters the second lower fertilizer pipe 372 through the second fertilizer pipe 530, so as to output fertilizer to the second lower fertilizer pipe 372.

[0081] The seeding mechanism 600 is used to output soybean seeds 140 to the upper end of each seeding tube 382 respectively.

[0082] Specific reference Figures 10-12The sowing mechanism 600 includes a seed hopper 610 and several seed metering devices 620. The seed hopper 610 is fixedly supported on the frame 200. The bottom of the seed hopper 610 is provided with several seed dispensing ports 611. Each seed metering device 620 is correspondingly located above each seed tube 382. Each seed metering device 620 includes a housing 621 and a seed dispensing wheel 622 installed in the housing 621. The housing 621 is fixedly supported on the frame 200. The upper part of the housing 621 is provided with a seed inlet 623, and the lower part of the housing 621 is provided with a seed outlet 624.
