Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to a method and a device for planting corn in saline-alkali land. Background Art

[0002] Saline-alkali land refers to land with excessive accumulation of salt and alkali components on the soil surface, which is harmful to the growth of crops. It includes salt land, alkali land, salinized land and alkaline land. This type of land is widely distributed around the world. From the frigid zone, temperate zone to the tropical zone, there are large amounts of saline, dry, compacted and barren saline-alkali land, accounting for almost 10% of the total land area. The soil in saline-alkali land has a high salt content, which has caused serious harm to the growth and development of corn. Salt will affect the root system's ability to absorb water, resulting in late emergence, slow growth and weak seedling vigor.

[0003] Traditional methods of managing saline-alkali land mostly use irrigation to wash away the salt in the surface soil. However, this method consumes a lot of water and only treats the symptoms rather than the root cause. Large soil evaporation will also lead to continued salinization of the soil. Therefore, we can gradually replace the soil, improve the soil's water retention capacity, and reverse the process of soil salinization. However, using traditional equipment to improve the soil and plant corn is labor-intensive and inefficient. Summary of the invention

DETAILED DESCRIPTION

[0030] 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.

[0031] To further understand the content of the present invention, Figure 1-Figure 8 The present invention is described in detail.

[0032] Example 1: A method for planting corn in saline-alkali land, which uses a method of replacing soil in a pit to eliminate the influence of saline-alkali land on the early development of corn seeds, so that the corn seeds can grow quickly and healthily to the jointing stage. The corn seedlings in the jointing stage can resist the influence of saline-alkali land to a certain extent, thereby increasing the germination rate and survival rate of corn seeds in saline-alkali land and improving grain yield. The method specifically comprises the following steps:

[0033] S1. Digging a seedling pit: When digging a seedling pit on saline-alkali land, you first need to choose a suitable location. These locations should avoid waterlogging and overly wet areas to prevent root rot. The depth and width of the excavated pit should be determined according to the growth needs of corn. Generally speaking, the size of the pit should be larger than the root length of the corn in the early jointing period so that the root system has enough space to develop. In addition, the excavated saline-alkali soil should be properly handled, such as piling it in a designated area or covering it with other fertile soil to reduce the impact on the environment;

[0034] S2. Filling the nutrient soil: Filling the seedling pit with fully decomposed nutrient soil is one of the key steps. This nutrient soil can be produced by composting corn stalks, and the amount of composting agent used is 40kg / hm 2 This method not only provides the necessary nutrients, but also helps improve the soil structure, making it more suitable for corn growth. When filling, make sure the soil is evenly distributed and lightly compacted to maintain good aeration and appropriate moisture;

[0035] S3. Sowing seeds for seedlings: Before sowing, make sure that the soil in each seedling pit is fully moistened and the temperature is controlled between 20 and 25°C, which helps to improve the germination rate of the seeds. Sow 4-6 corn seeds in each seedling pit. You can use a uniform sowing method, and keep a proper distance between each seed to avoid excessive competition. After sowing, cover with a thin layer of soil (about 3-5 cm), and then water to keep the soil moist. During the entire seedling process, it is very important to maintain appropriate humidity and temperature, which will directly affect the health and growth rate of the corn seedlings.

[0036] Example 2: In view of the fact that a method for planting corn in saline-alkali land needs to dig pits on hard saline-alkali land to change soil and sow seeds during implementation, the workload is extremely large, so it is necessary to improve work efficiency. A device for planting corn in saline-alkali land specifically includes a telescopic bracket 1, a movable roller 2 is provided on one side of the bottom of the telescopic bracket 1, a handrail 3 is provided on the top of the telescopic bracket 1, a supporting foot 4 is provided on the front of the telescopic bracket 1, a lifting guide rail 5 is fixedly connected to the telescopic bracket 1, a lifting slider 6 is slidably connected to the lifting guide rail 5, the lifting slider 6 is fixedly connected to a nutrient soil storage tank 7, a reset spring 8 is provided under the lifting slider 6, the lifting slider 6 is connected to a manual lifting adjustment mechanism 9, and the manual lifting adjustment mechanism 9 includes a limit guide rail 901, and the telescopic bracket 1 is fixedly connected to the lifting guide rail 5. The limited guide rail 901 is fixedly connected to the nutrient soil storage tank 7 with a height adjustment rod 902, and the end of the height adjustment rod 902 is movably connected to a lifting roller 903, and the lifting roller 903 rolls up and down along the limited guide rail 901. The telescopic bracket 1 is rotatably connected with a pressing lever 904, so that the pressing lever 904 can be pressed to push the lifting roller 903 to roll downward along the limited guide rail 901, thereby driving the nutrient soil storage tank 7 to descend for digging and sowing. After the nutrient soil storage tank 7 is released, the reset spring 8 will drive the nutrient soil storage tank 7 to reset;

[0037] A corn seed storage tank 10 is fixedly connected to the inside of the nutrient soil storage tank 7, and a planting pit excavation drill barrel 11 is rotatably connected to the bottom end of the nutrient soil storage tank 7. A drive motor 12 is fixedly installed on one side of the nutrient soil storage tank 7, and a first pulley 13 is fixedly connected to the drive motor 12. A second pulley 14 is fixedly connected to the planting pit excavation drill barrel 11, and the first pulley 13 and the first pulley 13 are connected by belt drive. When the nutrient soil storage tank 7 descends, the drive motor 12 can drive the planting pit excavation drill barrel 11 to rotate through the pulley drive to excavate the planting pit. The lower end of the planting pit excavation drill tube 11 is a conical surface, and a bottom spiral soil discharge blade 1101 is fixedly connected to the conical surface of the lower end of the planting pit excavation drill tube 11, so that when the planting pit excavation drill tube 11 rotates, the spiral soil discharge blade 1101 can discharge the soil to the surrounding areas, and the planting pit excavation drill tube 11 is fixedly connected with original soil lifting coils 1102 around it, which can lift the original soil discharged by the spiral soil discharge blade 1101 to the ground, thereby realizing the removal of salinized soil in the planting pit.

[0038] A nutrient soil quantitative supply mechanism 15 is provided at the lower end of the corn seed storage tank 10, and a quantitative feeding rod 16 is connected to the lower end of the nutrient soil quantitative supply mechanism 15, and a feeding coil 1602 is provided on the quantitative feeding rod 16. A nutrient soil drop port 1103 is opened at the lower end of the planting pit excavation drill tube 11, and a first sealing cone 1603 is fixedly connected to the lower end of the quantitative feeding rod 16. A corn seed supply coil 17 runs through the corn seed storage tank 10 and the nutrient soil quantitative supply mechanism 15. The nutrient soil quantitative supply mechanism 15 includes a first fixed sleeve 1501, which is fixedly connected to the bottom end of the corn seed storage tank 10. The first fixed sleeve 1501 is fixedly connected to the bottom end of the corn seed storage tank 10. A center sleeve 1502 is arranged in 501, the first fixed sleeve 1501 is sleeved on the outside of the quantitative feeding rod 16, the center sleeve 1502 is inserted into the quantitative feeding rod 16, and a first spiral pattern 1601 is arranged on the outer side of the upper end of the quantitative feeding rod 16. A first nut 1503 is arranged between the first fixed sleeve 1501 and the center sleeve 1502. The first nut 1503 cooperates with the first spiral pattern 1601. The bottom end of the first nut 1503 and the contact surface between the first fixed sleeve 1501 and the bottom surface of the first nut 1503 are processed with first engaging teeth 1504, and a first downward pressure spring 1505 is arranged above the first nut 1503. When the drilling tube 11 is pressed down during the excavation of the planting pit, the first sealing cone 1603 will be embedded in the nutrient soil drop port 1103, blocking the nutrient soil drop port 1103 for excavation. When the excavation is completed and the drilling tube 11 is lifted up, the quantitative feeding rod 16 will descend under the action of its own gravity and the first downward pressure spring 1505, so that the first downward pressure spring 1505 will disengage from the nutrient soil drop port 1103. At the same time, when the quantitative feeding rod 16 descends, it will push the first nut 1503 downward, so that the first nut 1503 is engaged and fixed with the first fixed sleeve 1501 through the first engaging tooth 1504, so that the first nut 1503 cannot rotate, and the thread lead angle of the first spiral pattern 1601 is greater than the friction angle. Therefore, when the first nut 1503 cannot rotate, the quantitative feeding rod 16 itself will rotate, and then a fixed amount of nutrient soil will be sent to the planting pit through the nutrient soil drop port 1103 through the feeding coil 1602.

[0039] A second sealing cone 1701 is fixedly connected to the lower end of the corn seed supply coil 17, a corn seed drop port 1604 is opened at the lower end of the quantitative feeding rod 16, a corn seed quantitative supply mechanism 18 is arranged at the upper end of the corn seed supply coil 17, the corn seed quantitative supply mechanism 18 includes a second fixed sleeve 1801, a second fixed sleeve 1801 is fixedly connected in the corn seed storage tank 10, the upper end of the corn seed supply coil 17 is inserted into the second fixed sleeve 1801, a second spiral pattern 1702 is machined on the upper end of the corn seed supply coil 17, a second nut 1802 is arranged in the second fixed sleeve 1801, the lower end of the second nut 1802 and the contact surface between the second fixed sleeve 1801 and the second nut 1802 are machined with second engaging teeth 1803, and a second downward pressure spring 1804 is arranged above the second nut 1802. Therefore, when the drilling drill 11 is pressed down during the excavation of the planting pit, the second sealing cone 1701 will be embedded in the corn seed drop port 1604 to block the corn seed drop port 1604. When the excavation of the planting pit is completed and the drilling drill 11 is lifted up, the corn seed supply coil 17 will descend under the action of its own gravity and the second downward pressure spring 1804. Similar to the quantitative supply mechanism of nutrient soil 15, the second nut 1802 is engaged with the second fixed sleeve 1801 through the second engaging tooth 1803. The corn seed supply coil 17 rotates with the cooperation of the second nut 1802 and the second spiral pattern 1702, and transports a certain amount of corn seeds downward into the planting pit.
