Description

Technical Field

[0001] The present invention relates to the technical field of agricultural seedling cultivation, and specifically relates to a temperature-controlled cultivation device and cultivation process for rootstock seedlings used in kiwifruit cultivation. Background Art

[0002] The cultivation of rootstock seedlings for kiwifruit cultivation refers to the process of cultivating and propagating rootstock seedlings to provide high-quality rootstock materials for kiwifruit grafting. The rootstock seedling refers to the bottom main stem part used for grafting, which mainly provides the root system and the overall growth framework, and the excellent kiwifruit variety will be grafted on the top.

[0003] However, there are still the following deficiencies in specific use:

[0004] 1. Existing devices usually pay more attention to the basic satisfaction of their nutrition and growth environment during the pretreatment stage of rootstock seedling cultivation, and do not need to pay too much attention to complex fertilizer treatment. Therefore, in the early stage of rootstock seedling cultivation, simplifying the production process can improve efficiency and reduce costs. However, the lack of stirring fertilizer during the pretreatment stage may lead to uneven mixing of fertilizers. Different types of fertilizers may have differences in particle size and concentration. The lack of a mixing process may result in uneven nutrient supply to rootstock seedlings during growth, affecting their growth and development. At the same time, the lack of stirring of fertilizers makes the mixing and treatment of fertilizers rely on manual operations, which may consume more time and labor and have low efficiency. This may be impractical and increase labor costs for large-scale rootstock seedling cultivation.

[0005] 2. In addition, existing rootstock seedling cultivation is usually carried out by manual fertilization. Manual fertilization can be targeted according to actual situations. Rootstock seedlings may face different problems at different growth stages and environmental conditions. By manual fertilization, nutrients can be supplemented or the nutrient ratio can be adjusted according to specific situations. At the same time, manual fertilization usually has lower investment costs and operating costs. However, manual fertilization may lead to uneven fertilization because different fertilization personnel may have differences in fertilization methods and skills. This may cause some areas of rootstock seedlings to receive excessive fertilizers while other areas lack nutrients, affecting the balanced growth and development of rootstock seedlings. In addition, manual fertilization is prone to fertilizer waste and loss. Over-fertilization or inaccurate fertilizer application may occur during fertilization, resulting in fertilizer loss and unnecessary resource waste, and may also cause environmental pollution.

[0006] Therefore, in view of this, the present invention proposes a temperature-controlled cultivation device and cultivation process for rootstock seedlings used in kiwifruit cultivation to make up for and improve the deficiencies of the existing technology. Summary of the Invention

[0007] To solve the above technical problems, the present invention provides a temperature-controlled cultivation device and a cultivation process for kiwifruit rootstock seedlings, so as to solve the technical problems raised in the above background technology.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A temperature-controlled cultivation device for kiwifruit rootstock seedlings, including a seedling cultivation support with a rectangular frame structure. Inside the seedling cultivation support, there are multiple seedling beds. At the top ends of the outer walls on both sides of the seedling cultivation support, there is a mixing and stirring mechanism, and at the bottom ends of the outer walls on both sides of the seedling cultivation support, there is a uniform spraying mechanism.

[0009] The mixing and stirring mechanism is used to mix different types of fertilizers. Mixing different types of fertilizers can provide comprehensive nutrients.

[0010] The uniform spraying mechanism is used to evenly spray the fertilizer on the soil surface for cultivating rootstock seedlings.

[0011] Further, the mixing and stirring mechanism includes a fixed long block fixedly installed at the bottom end of the seedling cultivation support. On the outer wall of the side of the fixed long block away from the seedling cultivation support, there is a square slide rail slidably connected. On the surface of the side of the square slide rail away from the fixed long block, there is a threaded rod slidably penetrating. At one end of the threaded rod close to the square slide rail, there is a connecting column fixedly installed. At the center of the bottom end of the seedling cultivation support, there are multiple obstacle columns fixedly installed evenly.

[0012] Further, the mixing and stirring mechanism also includes a sleeve threadedly connected to the outer wall of the threaded rod. At the bottom end of the threaded rod, there is a spring fixedly installed. On the outer wall of the sleeve, there is a material bucket fixedly installed. At one end of the spring away from the threaded rod, there is a stirring blade rotatably connected. On the outer wall of the side of the square slide rail close to the connecting column, there is a connecting block fixedly installed. The stirring blade is fixedly installed at the bottom end of the sleeve.

[0013] Further, the inner diameter of the top end of the connecting column is adapted to the inner diameter of the bottom end of the obstacle column, and the obstacle columns are distributed at intervals.

[0014] Further, the uniform spraying mechanism includes a runner fixedly connected to the outer wall of one end of the stirring blade away from the sleeve. On the outer wall of the side of the runner away from the stirring blade, there is a connecting rod rotatably connected. At one end of the connecting rod away from the runner, there is a swing rod rotatably connected. At one end of the swing rod away from the connecting rod, there is a rotating rod rotatably connected. At one end of the rotating rod away from the swing rod, there is a sliding rod rotatably connected.

[0015] Further, the uniform spraying mechanism also includes a sprayer rotatably connected to the outer wall of one end of the sliding rod away from the rotating rod. At the outer wall of one end of the sprayer away from the sliding rod, there is a feed pipe communicated. At the bottom end of the sliding rod, there is a transmission component drivingly connected.

[0016] Furthermore, one end of the feeding pipe away from the sprayer penetrates and communicates with the inner bottom end of the material bucket. One end of the transmission component away from the sliding rod is drivingly connected to the bottom end of the sprayer, and the transmission component is fixedly installed on the upper surface of one end of the connecting block away from the square slide rail.

[0017] Furthermore, a soil leveling screw rod is rotatably connected to the lower surface of one end of the connecting block away from the square slide rail, and a motor is fixedly installed inside the soil leveling screw rod.

[0018] Furthermore, a temperature-controlled cultivation device and a cultivation process for kiwifruit rootstock seedlings are provided, including the following steps:

[0019] Step 1: Select suitable rootstock varieties. Usually, rootstock varieties with strong growth ability, resistance to diseases and pests, and wide adaptability are selected. Common rootstocks include wild species and some cultivated species of kiwifruit.

[0020] Step 2: The operator places multiple seedling beds inside the seedling cultivation bracket and cultivates rootstock seedlings in the seedling beds. First, prepare the seedling cultivation substrate. A culture soil mixed with decomposed organic fertilizer and river sand can be selected. Fill the substrate into the seedling bed and level the surface. Then, sow the rootstock seeds on the substrate and cover a thin layer of soil. At the same time, maintain appropriate humidity.

[0021] Step 3: Appropriate nutrient supply is required during the growth of rootstock seedlings. According to the growth situation of the seedlings, appropriate topdressing can be carried out. By using the mixing and stirring mechanism and the uniform spraying mechanism in cooperation, larger fertilizer particles are broken, making them easier to dissolve and absorb. At the same time, the fertilizer is evenly dispersed in the soil for cultivating rootstock seedlings, which helps the dissolution and full absorption of the fertilizer. Generally, topdressing can be carried out every once in a while during the growth peak period, using organic or inorganic fertilizers suitable for rootstock seedlings.

[0022] Step 4: Regularly check the health status of rootstock seedlings, promptly discover and handle pest and disease problems. Appropriate pesticides can be used for spraying or other prevention and control measures to ensure the healthy growth of rootstock seedlings.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) The present invention utilizes the cooperation of a threaded rod, a sleeve, and a stirring blade. The mixing and stirring mechanism can fully mix different types of fertilizers together, ensuring the uniform distribution of nutrients in the fertilizers. This helps to provide the comprehensive nutrition required by the rootstock seedlings, promoting their healthy growth and development. At the same time, the mixing and stirring mechanism can crush and refine larger fertilizer particles, making them easier to dissolve and absorb. The finely crushed fertilizer particles help to improve the utilization rate of nutrients, enabling the rootstock seedlings to absorb nutrients more effectively and promoting their growth. In addition, the mixing and stirring mechanism can adjust the fertilizer ratio according to the growth needs of the rootstock seedlings. Different stages of rootstock seedlings have different nutrient requirements, and through the mixing and stirring mechanism, the ratio can be adjusted as needed to provide an appropriate nutrient supply. Finally, the mixing and stirring mechanism can achieve the automated mixing and processing of fertilizers, improving the fertilization efficiency. Compared with manual fertilizer mixing, the stirring blade can mix fertilizers more quickly and evenly, saving time and labor costs.

[0025] (2) The present invention utilizes the cooperation of a sliding rod, a rotating rod, and a sprayer. The uniform spraying mechanism can evenly spray fertilizers on the soil surface around the rootstock seedlings, ensuring the uniform distribution of nutrients. This helps to avoid the application of fertilizers in cases of local excess or deficiency, providing a balanced nutrient supply. At the same time, evenly spraying fertilizers can reduce the waste and overuse of fertilizers. It can provide an appropriate amount of fertilizers according to the needs of the rootstock seedlings, avoiding the overuse of fertilizers, saving fertilizer costs and reducing environmental pollution. In addition, the uniform spraying mechanism can achieve the automated spraying of fertilizers, improving the fertilization efficiency. Compared with manual fertilization, the sprayer can spray fertilizers more quickly and evenly, saving time and labor costs. Evenly spraying fertilizers helps to achieve the uniform distribution of fertilizers in the soil, providing the balance of nutrient supply, which is conducive to the balanced absorption of nutrients by the rootstock seedling roots and promoting the improvement of the absorption and utilization efficiency of nutrients.

[0026] (3) The present invention utilizes the cooperation between a motor and a soil leveling screw rod. The soil leveling screw rod can help level the soil surface neatly, which is very important for the planting and growth of rootstock seedlings. Because a flat soil surface can provide a uniform growth environment, avoiding problems such as lodging or distortion of rootstock seedlings caused by uneven soil height. At the same time, the soil leveling screw rod can automate the task of soil leveling, reducing the workload and labor intensity of manual operation. Compared with the traditional method of manually leveling the soil, using the soil leveling screw rod can save time and human resources, and the soil leveling screw rod can quickly and efficiently complete the task of soil leveling. It can cover a large area of soil in a short time, improve work efficiency, and ensure the uniformity of the soil in the entire rootstock seedling planting area. The soil leveling screw rod can ensure the flatness of the soil surface, which helps to maintain the humidity balance in the soil. It can avoid water concentration or loss caused by unevenness on the soil surface, helping rootstock seedlings to fully absorb soil moisture and maintain appropriate moisture conditions. Finally, by using the soil leveling screw rod to level the soil, the planting quality of rootstock seedlings can be improved. A flat soil surface helps the growth and expansion of the root system of rootstock seedlings, provides a stable growth environment, and promotes their healthy growth and development.

Because a flat soil surface can provide a uniform growth environment and avoid problems such as lodging or distortion of rootstock seedlings caused by uneven soil surface.

[0048] Embodiment 2

[0049] The above-mentioned temperature-controlled cultivation process for rootstock seedlings used in kiwifruit planting includes the following steps:

[0050] Step 1: Select suitable rootstock varieties. Usually, rootstock varieties with strong growth ability, resistance to pests and diseases, and wide adaptability are selected. Common rootstocks include wild species and some cultivated species of kiwifruit.

[0051] Step 2: The operator places multiple seedling beds 11 inside the seedling cultivation bracket 1 and cultivates rootstock seedlings in the seedling beds 11. First, prepare the seedling cultivation substrate. A culture soil mixed with decomposed organic fertilizer and river sand can be selected. Fill the substrate into the seedling bed 11 and level the surface. Then sow the rootstock seeds on the substrate and cover a thin layer of soil. At the same time, maintain appropriate humidity.

[0052] Step 3: Rootstock seedlings need appropriate nutrient supply during the growth process. Appropriate topdressing can be carried out according to the growth situation of the seedlings. By using the mixing and stirring mechanism 2 and the uniform spraying mechanism 3 in combination, larger fertilizer particles are broken, making them easier to dissolve and absorb. At the same time, the fertilizer is evenly dispersed in the soil for cultivating rootstock seedlings, which helps the dissolution and full absorption of the fertilizer. Generally, topdressing can be carried out once every once in a while during the growth peak period, using organic or inorganic fertilizers suitable for rootstock seedlings.

[0053] Step 4: Regularly check the health status of rootstock seedlings, promptly discover and handle pest and disease problems. Appropriate pesticides can be used for spraying or other prevention and control measures to ensure the healthy growth of rootstock seedlings.

[0054] The following are the complete usage steps and working principles of the above embodiments:

[0055] This device is mainly used for: The seedling cultivation support 1 is to support and protect the growth of rootstock seedlings, ensuring their straight and stable growth. During the growth process, rootstock seedlings require good support to prevent toppling and distortion, and at the same time resist wind and external pressure. Secondly, there are multiple seedbeds 11 placed inside the seedling cultivation support 1, which are special areas for planting and cultivating rootstock seedlings. In addition, operators can provide suitable soil or substrate in the seedbeds 11 to meet the growth requirements of rootstock seedlings;

[0056] The mixing and stirring mechanism 2 is used to mix different types of fertilizers. Mixing different types of fertilizers can provide comprehensive nutrients. When the mechanism is specifically used:

[0057] As Figure 3 shown, a fixed long block 21 is fixedly installed at the bottom end of the seedling cultivation support 1, and a square slide rail 22 is slidably connected to the outer wall of the fixed long block 21. When the rootstock seedlings placed inside the seedbed 11 need to be fertilized, the operator first pours the fertilizer into the material bucket 27, and then can push the connecting block 29 to move to the left. Since the connecting block 29 is fixedly installed on one outer wall of the square slide rail 22, pushing the connecting block 29 to move to the left will synchronously drive the square slide rail 22 to slide on the outer wall of the fixed long block 21. In addition, a threaded rod 23 is slidably connected through one side of the square slide rail 22 close to the connecting block 29, and a connecting column 24 is fixedly installed at the top end of the threaded rod 23. Therefore, as Figure 4 shown, when the square slide rail 22 slides until the connecting column 24 abuts against the obstacle column 210, as the square slide rail 22 continues to move, the obstacle column 210 will squeeze the connecting column 24. Thus, the connecting column 24 will push the threaded rod 23 to move downward. Moreover, a spring 26 is fixedly installed at the bottom end of the threaded rod 23. When the threaded rod 23 moves downward, it will squeeze the spring 26. In addition, the outer wall of the threaded rod 23 is threadedly connected with a sleeve 25, and a stirring blade 28 is fixedly installed at the bottom end of the sleeve 25. Therefore, when the threaded rod 23 moves downward, it will cause the sleeve 25 to rotate counterclockwise. By the counterclockwise rotation of the sleeve 25, the stirring blade 28 fixedly installed at the bottom end of the sleeve 25 will be driven to rotate counterclockwise. In this way, the stirring blade 28 rotating counterclockwise in the material bucket 27 can stir the fertilizer placed in the material bucket 27. In addition, when the connecting column 24 moves away from touching the obstacle column 210, the spring 26 after being squeezed will reset, and then push the threaded rod 23 to move upward in the reverse direction. At this time, the sleeve 25 and the stirring blade 28 that have rotated counterclockwise will change to rotate clockwise, and then the rotation stops;

[0058] Summary 1: Compared with the prior art, there is a lack of pretreatment and stirring of fertilizers. This mechanism enables the sleeve 25 to rotate counterclockwise when the threaded rod 23 moves downward. The counterclockwise rotation of the sleeve 25 will synchronously drive the stirring blade 28 fixedly installed at the bottom of the sleeve 25 to rotate counterclockwise. In this way, the stirring blade 28 rotating counterclockwise in the material bucket 27 can stir the fertilizers placed in the material bucket 27. The mixing and stirring mechanism 2 can fully mix different types of fertilizers together, ensuring the uniform distribution of nutrients in the fertilizers. This helps to provide the comprehensive nutrition required by the rootstock seedlings, promoting their healthy growth and development. At the same time, the mixing and stirring mechanism 2 can crush and refine larger fertilizer particles, making them easier to dissolve and absorb. The finely crushed fertilizer particles help to improve the utilization rate of nutrients, enabling the rootstock seedlings to absorb nutrients more effectively and promoting their growth. In addition, the mixing and stirring mechanism 2 can adjust the fertilizer ratio according to the growth needs of the rootstock seedlings. Rootstock seedlings at different stages have different nutrient requirements, and the mixing and stirring mechanism 2 can adjust the ratio as needed to provide an appropriate nutrient supply. Finally, the mixing and stirring mechanism 2 can achieve the automatic mixing and processing of fertilizers, improving the fertilization efficiency. Compared with manually mixing fertilizers, the stirring blade 28 can mix fertilizers more quickly and evenly, saving time and labor costs. In addition, compared with using a motor to control the rotation of the stirring blade 28 to mix fertilizers, manually pushing the mechanical structure does not require additional power drive and does not consume electric power resources, thus saving energy costs. At the same time, the manually pushed mechanical structure can be adjusted and controlled according to needs. The pushing force and speed can be adjusted according to specific circumstances to adapt to different fertilizer types and characteristics. Moreover, the manually pushed mechanical structure is generally simpler and cheaper compared to the motor-driven mechanical structure. It does not require a motor and an electrical control system, reducing the complexity and cost of the equipment;

[0059] The uniform spraying mechanism 3 for evenly spraying fertilizers on the soil surface for cultivating rootstock seedlings is specifically used as follows:

[0060] Such as Figure 5As shown in the figure, a runner 31 is fixedly connected to the bottom end of the stirring blade 28. Therefore, when the stirring blade 28 rotates, the runner 31 will rotate synchronously. In addition, the bottom end of the runner 31 is rotatably connected to a connecting rod 32, and one end of the connecting rod 32 away from the runner 31 is rotatably connected to a swing rod 33. Thus, when the runner 31 rotates counterclockwise following the stirring blade 28, the connecting rod 32 will swing counterclockwise to the left synchronously, and will pull the swing rod 33 to deflect and move to the left synchronously. Furthermore, one end of the swing rod 33 away from the connecting rod 32 is rotatably connected to a rotating rod 34, and one end of the rotating rod 34 away from the swing rod 33 is rotatably connected to a sliding rod 35. Thus, when the connecting rod 32 pulls the swing rod 33 to deflect and move to the left, the swing rod 33 will pull the rotating rod 34 to deflect and move to the left synchronously. In addition, when the rotating rod 34 deflects and moves to the left, it will pull the sliding rod 35 to deflect and move to the right. Since one end of the sliding rod 35 away from the rotating rod 34 is drivingly connected to a transmission component 38, when the sliding rod 35 deflects and moves to the right, it will drive the end of the transmission component 38 close to the sprayer 36 to deflect and move to the right synchronously. Therefore, when the sliding rod 35 deflects and moves to the right, the sprayer 36 rotatably connected to the end of the sliding rod 35 away from the rotating rod 34 will deflect and move to the right synchronously with the deflection and movement of the sliding rod 35 to the right. Therefore, as Figure 6 shown, the feed pipe 37 connected to the upper end of the sprayer 36 will convey the fertilizer stirred inside the material bucket 27, and finally evenly spray it onto the inner surface of the seedbed 11 through the swing track of the sprayer 36;

[0061] Summary II: Compared with the prior art that requires manual single spraying and irrigation of fertilizers, this mechanism realizes that when the sliding rod 35 deflects and moves to the right, the sprayer 36 rotatably connected to the end of the sliding rod 35 away from the rotating rod 34 will deflect and move to the right synchronously with the deflection and movement of the sliding rod 35 to the right. Therefore, the feed pipe 37 connected to the upper end of the sprayer 36 will convey the fertilizer stirred inside the material bucket 27, and finally evenly spray it onto the inner surface of the seedbed 11 through the swing track of the sprayer 36. The uniform spraying mechanism 3 can evenly spray the fertilizer on the soil surface around the rootstock seedlings, ensuring the uniform distribution of nutrients. This helps to avoid the application of fertilizers in cases of local excess or deficiency, providing a balanced nutrient supply. At the same time, evenly spraying fertilizers can reduce the waste and overuse of fertilizers. It can provide an appropriate amount of fertilizer according to the needs of the rootstock seedlings, avoid the overuse of fertilizers, save fertilizer costs and reduce environmental pollution. In addition, the uniform spraying mechanism 3 can realize the automatic spraying of fertilizers, improving the fertilization efficiency. Compared with manual fertilization, the sprayer 36 can spray fertilizers more quickly and evenly, saving time and labor costs. Evenly spraying fertilizers helps the uniform distribution of fertilizers in the soil, providing the balance of nutrient supply, which helps the balanced absorption of nutrients by the rootstock seedling roots and promotes the improvement of the absorption and utilization efficiency of nutrients;

[0062] When the soil leveling spiral rod 444 mechanism for balancing the soil is specifically used:

[0063] As Figure 7 shown, a motor is installed inside the soil leveling screw rod 444. When the operator pushes the connecting block 29 to move horizontally, the motor starts and drives the soil leveling screw rod 444 to rotate. Due to the spiral shape of the soil leveling screw rod 444 and the pointed tip at the end, the friction between it and the soil can be increased, enabling it to be better anchored in the soil. When the soil leveling screw rod 444 rotates, it forms an anchor point in the soil and can withstand a certain amount of anti-thrust and torque. In addition, the spiral shape of the soil leveling screw rod 444 enables it to cut and push the soil when rotating. When the soil leveling screw rod 444 rotates, the spiral blades can gradually cut and lift the soil fragments and then push them to the top or side of the screw rod. Then, the rotated soil leveling screw rod 444 will level the soil surface inside the seedbed 11;

[0064] Summary III: Compared with the prior art that requires manual unified soil leveling, this mechanism enables the soil leveling screw rod 444 to help level the soil surface neatly, which is very important for the planting and growth of rootstock seedlings. Because a flat soil surface can provide a uniform growth environment and avoid problems such as lodging or distortion of rootstock seedlings caused by uneven soil. At the same time, the soil leveling screw rod 444 can automatically complete the task of soil leveling, reducing the workload and labor intensity of manual operation. Compared with the traditional manual soil leveling method, using the soil leveling screw rod 444 can save time and human resources, and the soil leveling screw rod 444 can quickly and efficiently complete the task of soil leveling. It can cover a large area of soil in a short time, improve work efficiency, and ensure the uniformity of the soil in the entire rootstock seedling planting area.
