TECHNICAL FIELD

[0001] The utility model belongs to the field of crop planting, and particularly relates to a salt and alkali soil high sudang grass and sesbania grandiflora zonal planting device. BACKGROUND

[0002] Planting machines are specialized mechanical equipment used in agricultural production, mainly for seeding, tree planting, seedling raising, and other planting processes. They can help farmers improve labor efficiency, reduce labor costs, ensure uniform distribution of seeds, and improve crop growth quality. Planting machines have different types and designs under different environmental and crop demands. Here are some main functions and types of planting machines.

[0003] Existing planting equipment is mostly used for single crop planting, and its effect on simultaneous seeding of two crops is very limited. The optimal planting ratio of high sudang grass and sesbania grandiflora is 2:4, making it difficult for traditional seeding equipment to meet the needs of high sudang grass and sesbania grandiflora 2:4 planting.

[0004] Therefore, to solve the problem of existing seeding machines that cannot automatically seed high sudang grass and sesbania grandiflora seeds according to a 2:4 ratio, a salt and alkali soil high sudang grass and sesbania grandiflora zonal planting device is developed. By adding a double-seed seeding structure and an automatic feeding control structure to the seeding machine, high sudang grass and sesbania grandiflora seeds can be automatically and efficiently planted according to the planting needs in a 2:4 ratio.

Detailed Implementation

[0026] Silage corn is a major feed source in the arid desert oasis areas of southern Xinjiang. However, in recent years, due to the increasing secondary salinization of the soil and extreme scarcity of freshwater resources, silage corn production has suffered from reduced yields, lower quality, and lower economic benefits. Sorghum has better salt and alkali tolerance and drought resistance than silage corn, and people have begun to introduce forage sweet sorghum as a substitute. Livestock farmers use freshly harvested sorghum for feeding, which has significant advantages. However, forage sorghum has a high water content and low starch content, making it less acceptable in large-scale farms. Sorghum-Sudan grass, a hybrid of sorghum and Sudan grass, is an annual herbaceous plant. It has a well-developed root system, thick stems, and large leaves; it has strong tillering and regeneration capabilities, is drought-resistant, and highly adaptable, and can be planted in saline soil (0.4%), sandy loam, clay loam, or slightly acidic soil. Sesbania is highly adaptable, tolerant of salt, waterlogging, poor soil, drought, and diseases and wind; it can grow in saline soil (0.6%) or alkaline soil (pH 9.5). Sorghum has a short growing season, coinciding with that of sesbania. Harvesting sorghum during its heading-doughing stage coincides with the flowering-fruiting stage of sesbania, when the moisture content is ideal for silage. Therefore, strip planting of sorghum and sesbania results in well-rounded forage with high feed value. Based on this, different row ratios of 2:2, 4:2, 4:4, and 6:4 were used for planting sorghum and sesbania, with a plant spacing of 15cm, a row spacing of 50cm, and a 60cm overlap between rows. The optimal row ratio was selected, and a 4:2 row ratio strip planting device was invented. A special lactic acid bacteria fermentation promoter was also developed for mixed sorghum and sesbania silage, using a 2:1 ratio of *Lactobacillus plantarum* and *Lactobacillus brunelli* at an inoculation rate of 105 cfu / kg to improve fermentation quality.

[0027] Two rows of Sorghum sulphureus and two rows of Sesbania serratifolia were planted in a 2:2 ratio (S2C2), four rows of Sorghum sulphureus and two rows of Sesbania serratifolia were planted in a 4:2 ratio (S4C2), four rows of Sorghum sulphureus and four rows of Sesbania serratifolia were planted in a 4:4 ratio (S4C4), and six rows of Sorghum sulphureus and two rows of Sesbania serratifolia were planted in a 6:4 ratio (S6C2) (Figure). Sorghum sulphureus and Sesbania serratifolia were planted in four treatments with different row ratios: 2:2, 4:2, 4:4, and 6:4. The plant spacing was 15 cm, the row spacing was 50 cm, and the overlap row spacing was 60 cm.

[0028] Sorghum oleraceus seeds are flat-ovoid or round-ovoid, and their color varies depending on the variety, ranging from yellow, brownish-black, to black. The thousand-seed weight also varies considerably depending on the variety, generally around 10 grams. The sowing rate is 2.0 kg per mu (approximately 0.067 hectares) for row sowing or hill sowing, with a sowing depth of 2.0 cm. Sesbania serratifolia seeds are short-rectangular, nearly square, or nearly spherical, about 4 mm long and 2-3 mm in diameter. The seed coat is greenish-brown, brown, light blue, or has black markings. The thousand-seed weight is 12-18 grams. Sesbania serratifolia has poor soil penetration, so the soil covering should not be too deep, generally around 2 cm. Based on previous data from trials using sorghum oleraceus and sesbania serratifolia as forage, the most suitable planting pattern is 4:2, i.e., four rows of sorghum oleraceus followed by two rows of sesbania serratifolia, arranged alternately. Both sesbania and sorghum are best sown at a depth of 2 cm. Both seeds are somewhat spherical in shape. Using existing forage seeders and planting methods, hill-sowing can be employed. A seeder with a seed metering device and an independent seed box should be selected. A three-film seeder should be used, with sorghum sown in the first two films and sesbania in the third. The plant spacing should be 15 cm, the row spacing 50 cm, and the overlap row 60 cm. Using this planting method, both forages can be harvested and fermented in a single batch at the silage stage, achieving the six technical advantages mentioned earlier.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please see Figures 1-9 This utility model provides an embodiment of a strip planting device for Sorghum oleraceus and Sesbania serratifolia in saline-alkali land, comprising a movable frame 1, a seeding rack 4, a furrowing rack 8, and a vehicle-mounted frame 7, and further comprising a seed tank 5, a furrowing plow 6, an electric seeder 9, and a microprocessor 20. The vehicle-mounted frame 7 is fixedly connected to the upper edge of the movable frame 1, the furrowing rack 8 is fixedly connected to the lower end of the movable frame 1, the seeding rack 4 is fixedly connected to the left edge of the movable frame 1, the lower end of the seeding rack 4 is equipped with equidistantly distributed electric seeders 9, the upper end of the seeding rack 4 is provided with equidistantly distributed threaded grooves 11, and the lower outer wall of the seed tank 5 is provided with external threads 10. The seed tank 5 is connected to the electric seeder 9 at the feed end, which is compatible with the screw groove 11. The upper end of the seed tank 5 is equipped with a feed hopper 21. The inner wall of the seed tank 5 is fixed with a centrally mounted partition 22. The lower end of the partition 22 is provided with a rotating groove 27. The lower opening of the seed tank 5 is fixed with a ring frame 26. The lower end of the ring frame 26 is equipped with a servo motor 24. The output end of the servo motor 24 passes through the inner wall of the ring frame 26 and is fixed with a rotary switch 23. The upper and lower edges of the rotary switch 23 are provided with through holes 25. The rotary switch 23 is compatible with the rotating groove 27. The inner wall of the furrowing frame 8 is rotatably mounted with a furrowing plow 6.

[0031] The seed tank 5, which has a partition 22, can store sorghum and sesbania seeds. The microprocessor 20 controls the rotation of the servo motor 24, which in turn drives the rotary switch 23 to rotate. This allows the selection of seeds that can be output downwards through the through hole 25 according to the sowing needs. The electric seeder 9 then automatically sows the selected seeds. The external thread 10 on the seed tank 5 allows workers to easily rotate and remove it from the screw groove 11 for maintenance or cleaning. The feed hopper 21 on the seed tank 5 also allows workers to replenish seeds in a timely manner.

[0032] Please see Figures 3-7 In this embodiment, a second hinged bracket 16 symmetrically distributed on the left and right sides is installed at the center of the frame of the mobile frame 1. A mudguard 3 is fixedly connected to the second hinged bracket 16. During use, the mudguard 3 can block the dust generated by the trenching plow 6 during operation to prevent it from splashing everywhere. An auxiliary frame 13 is fixedly connected to the lower end of the soil covering plate 2. A moving wheel 15 is rotatably installed on the auxiliary frame 13. During use, the moving wheel 15 can assist the soil covering plate 2 to move with the mobile frame 1. A housing 12 is fixedly connected to the center of the upper end of the mobile frame 1. A top cover 19 is bolted to the upper end of the microprocessor 20. During use, the housing 12 and the top cover 19 can protect the microprocessor 20 inside to prevent it from being damaged by foreign objects. The top cover 19 is bolted to the upper outer wall of the housing 12. The microprocessor 20 is compatible with the housing 12. During use, the bolt fixing method can facilitate workers to disassemble and maintain the top cover 19 and the housing 12.

[0033] Please see Figures 3-4 In this embodiment, hydraulic cylinders 17 are fixedly connected to the front edge of the trenching frame 8, which are symmetrically distributed. A hinge seat 18 is fixedly connected to the output end of the hydraulic cylinder 17. In use, the hydraulic cylinder 17 can drive the soil covering plate 2, which is hinged to the trenching frame 8, to adjust to different angles to ensure the working effect of the soil covering plate 2. The left and right ends of the trenching frame 8 are fixedly connected to the first hinge bracket 14, and the soil covering plate 2 is hinged to the first hinge bracket 14. The hinge seat 18 is hinged to the center of one end close to the soil covering plate 2. In use, the first hinge bracket 14 and the hinge seat 18 can assist the hydraulic cylinder 17 in driving the soil covering plate 2 to perform automatic adjustment.

[0034] Before use, first pour the sorghum and sesame seeds into the seed container 5 in the order of left and right, and store them separately by the partition 22. Then, install the vehicle frame 7 onto the mobile vehicle by using the hook.

[0035] During sowing, the mobile frame 1 is moved by the mobile carrier, and the furrowing plow 6 is used to open furrows in the soil. The microprocessor 20 controls the rotation of the servo motor 24, which in turn drives the rotary switch 23 to rotate. The sorghum and sesbania seeds are dropped and output into the electric seeder 9 in the manner of sowing sorghum in the first two films and sesbania in the third film. The electric seeder 9 automatically sows the sorghum and sesbania seeds according to the sowing plant spacing of 15cm, row spacing of 50cm, and intersection row spacing of 60cm.

[0036] Next, the microprocessor 20 rotates and adjusts the soil covering width of the covering plate 2 according to the planting method, so that the soil after the furrow is opened can be covered back onto the seeds during planting.

[0037] Through the above steps, the seed tank 5 with the internal partition 22 can store sorghum and sesbania seeds, and the microprocessor 20 controls the rotation of the servo motor 24. The servo motor 24 drives the rotary switch 23 to rotate, so as to select the seeds that can be output downward through the through hole 25 according to the sowing needs. The electric seeder 9 automatically sows the selected seeds. The external thread 10 on the seed tank 5 makes it easy for workers to rotate and remove it from the screw groove 11 for maintenance or cleaning. The feed hopper 21 on the seed tank 5 also makes it easy for workers to replenish seeds in a timely manner. This solves the problem that existing seeders are difficult to automatically sow sorghum and sesbania seeds according to a 2:4 ratio.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
