Description

Technical Field

[0001] The invention relates to the technical field of glutinous yam planting, in particular to a glutinous yam horizontal shaping growth cultivation device. Background Art

[0002] Glutinous yam is a kind of yam, which has extremely high medicinal value. The cultivation method of glutinous yam is different from that of other plants. It is to cut the tubers of mature glutinous yam, and grow glutinous yam through the development of tubers. During the growth process, the tubers grow stems and leaves.

[0003] The existing glutinous yam grows vertically downward during cultivation. After maturity, it needs to be harvested with the help of excavating equipment. Since the growth length of the glutinous yam is long, the excavation depth requirement is high, which will affect the harvesting efficiency of the glutinous yam. At the same time, it grows vertically downward without any obstruction, so the tubers of the glutinous yam will grow to the place where the nutrient source is sufficient. Most of the glutinous yams will bend, and the mature glutinous yams are poor. Therefore, the publication number CN215992084U discloses a yam horizontal fixed growth cultivation device, which includes a planting substrate and a guide extension cover, a support pad is provided on the bottom of the planting substrate, and the top of the guide extension cover is arranged at the bottom of the planting substrate, and the two are connected to each other, and at least one guide tube is provided on the side of the guide extension cover in the same direction or reverse direction, and a limiting cover is connected to the guide tube, and the limiting cover has a variety of different structural forms.

[0004] The above-mentioned yam horizontal fixed growth cultivation device can effectively guide and limit the growth of yam through the cooperation of the planting base, the guide extension cover and the limiting cover, and effectively solve the problems of low harvesting efficiency of yam, requiring a lot of manpower and material resources, increasing production costs, being easily damaged, reducing its economic value, having different sizes and specifications, and low commercial rate.

[0005] However, when the above-mentioned yam horizontal fixed growth cultivation device is used, a large amount of nutrient solution is needed to meet the growth of the yam. Due to the short root system of the yam during the growth stage, the nutrient solution needs to fill the entire limiting cover to ensure that the root system fully absorbs the nutrient solution. This will cause excess nutrient solution and lead to nutrient solution loss. At the same time, when the nutrient solution is filled, the growth direction of the yam is completely limited by the limiting cover, and the yam is physically guided through the limiting cover. The yam is hindered by the limiting cover during the growth process, which will affect the growth rate and quality of the yam. At the same time, the operation during picking is cumbersome and the picking efficiency is low.

[0006] Therefore, a novel glutinous yam transverse shaping growth cultivation device can be adopted to solve the shortcomings of the prior art. Summary of the invention

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. When cultivating glutinous yam, the device for cultivating glutinous yam with transverse shaping growth physically guides the growth direction of the glutinous yam by setting a cultivation component, and shapes the glutinous yam so that the glutinous yam grows transversely in a specific shape along the cultivation component, and the growth depth is shallow, which is convenient for picking after maturity. At the same time, the transverse growth is conducive to the absorption of nutrients, so that each part of the glutinous yam absorbs more evenly, which is conducive to the growth of the glutinous yam.

[0025] 2. When cultivating glutinous yam, the nutrient solution conveying assembly is provided to convey nutrient medium solution to the glutinous yam in the cultivation assembly, and the conveying amount of the medium solution can be automatically controlled according to the growth stage. In addition, the conveying position of the medium solution can be controlled according to different growth stages to ensure that the input position of the medium solution is exactly the position where the glutinous yam grows, to avoid excessive filling of the medium solution to the position where the glutinous yam has not grown, and to effectively reduce the loss of the medium solution;

[0026] At the same time, the input of culture medium liquid is controlled according to the growth stage, so that the culture medium liquid gradually spreads from the starting position of the cultivation component to the end position of the cultivation component. As the glutinous yam grows, its root system will grow to places with sufficient nutrients. Therefore, the gradual advancement of culture medium liquid has a biological guiding effect on the glutinous yam, reduces the impact of physical guidance on the glutinous yam, and effectively improves the growth rate and quality of the glutinous yam.

[0027] 3. When cultivating glutinous yam, the device for cultivating glutinous yam with horizontal fixed growth inputs oxygen into the cultivation component by setting a ventilation component, thereby providing sufficient oxygen for the growth of glutinous yam. At the same time, it also has the function of guiding air and ventilation into the cultivation component, thereby reducing the probability of root rot during the growth of glutinous yam.

[0028] 4. When cultivating glutinous yam, the device for cultivating glutinous yam with horizontal shaping growth guides the glutinous yam seedlings by setting a seedling guide component to ensure that the seedlings maintain vertical growth, which is beneficial to the photosynthesis of the seedlings. At the same time, the vertical growth helps the glutinous yam to form a solid trunk and branches, thereby improving the ability to resist wind and pressure and increasing the durability of the plant.

[0029] 5. When the glutinous yam is picked, the upper cultivation tube is driven to rotate by the rotating mechanism to separate the upper cultivation tube from the lower cultivation tube, and the upper partition net is also separated from the lower partition net. At this time, the glutinous yam located between the upper partition net and the lower partition net will be directly exposed, making picking more convenient and improving picking efficiency.

[0030] In summary, the present invention not only enables the glutinous yam to grow horizontally through physical guidance, but also provides biological guidance to enable the glutinous yam to automatically grow horizontally during growth, thereby reducing the adverse effect of physical guidance on the growth of the glutinous yam and promoting the growth of the glutinous yam. In addition, the upper cultivation tube can be automatically opened to expose the glutinous yam in the cultivation component, which is convenient to operate and improves the picking efficiency of the glutinous yam.

DETAILED DESCRIPTION

[0046] 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.

[0047] Example 1: Reference Figure 1-Figure 7 , Figure 9-13 A glutinous yam horizontal fixed growth cultivation device comprises a support 1 and a storage box 2, wherein the storage box 2 stores a culture medium, and the concentration and nutrients of the culture medium need to be adaptively changed at different growth stages;

[0048] A cultivation component 3 is installed on the bracket 1 to cultivate yam and guide the yam to make it grow horizontally. The yam here refers to glutinous yam. The purpose of making the glutinous yam grow horizontally is to reduce the growth depth of the glutinous yam and facilitate picking after maturity. At the same time, the horizontal growth is beneficial to the absorption of nutrients, so that each part of the glutinous yam absorbs more evenly, which is beneficial to the growth of the glutinous yam.

[0049] The cultivation assembly 3 includes multiple upper cultivation tubes 6 and multiple lower cultivation tubes 7, each of which is fixedly connected to the bracket 1, and an upper partition net 9 and a lower partition net 10 are slidably installed in each upper cultivation tube 6 and each lower cultivation tube 7, respectively, and a cultivation layer 26 is filled between each upper partition net 9 and the corresponding upper cultivation tube 6, and between each lower partition net 10 and the corresponding lower cultivation tube 7.

[0050] The upper partition net 9 and the lower partition net 10 are both made of arc-shaped steel wire mesh. The upper partition net 9 and the lower partition net 10 form a partition net cover, and the mesh size is larger than the root diameter of the glutinous yam, making it easier for the root to insert into the cultivation layer 26 to absorb nutrients. At the same time, the size of the mesh size also needs to meet the particle size of the material in the cultivation layer 26 and will not fall.

[0051] The upper cultivation tube 6 and the lower cultivation tube 7 form a cultivation tube, and the diameter of the cultivation tube is slightly larger than the tuber diameter of the glutinous yam to prevent the cultivation tube from generating greater resistance to the growth of the tuber, which is beneficial to the normal growth of the glutinous yam. The difference between the diameter of the glutinous yam tuber and the diameter of the cultivation tube is controlled between 3-5 mm.

[0052] The cultivation layer 26 is composed of a variety of fluffy soilless cultivation materials, including coconut bran, perlite, vermiculite and ceramsite porous granular materials. These materials have excellent air permeability, water retention and water conductivity, and can smoothly guide the nutrient base liquid to the root position of the glutinous yam to ensure the root system's absorption of the nutrient base liquid. At the same time, the high air permeability can effectively reduce the probability of root rot.

[0053] A plurality of cross bars are fixedly mounted on the bracket 1 , and two insert tubes 13 are fixedly mounted on each cross bar. Two insert cones 23 are fixedly mounted on the bottom of each lower cultivation tube 7 , and each insert cone 23 is inserted into a corresponding insert tube 13 .

[0054] When installing the cultivation pipe, the insert cone 23 is inserted into the corresponding insert tube 13 to fix the lower cultivation pipe 7. A damping design is adopted between the insert cone 23 and the insert tube 13, which has a certain resistance and improves the stability of the insertion. The end of the insert cone 23 is designed in a cone shape, which is convenient for inserting into the soil or a soft foam board for fixation.

[0055] A rotating mechanism is installed between the bracket 1 and multiple upper cultivation tubes 6, and the rotating mechanism includes a fixed frame 14 fixedly installed on the bracket 1, a rotating shaft 17 fixedly installed on the fixed frame 14, a fixed truss 15 rotatably installed on the rotating shaft 17, each upper cultivation tube 6 is fixedly connected to the fixed truss 15, an electric push rod 16 is rotatably installed on the fixed frame 14, and the telescopic end of the electric push rod 16 is rotatably connected to the fixed truss 15.

[0056] The extension and retraction of the telescopic end of the electric push rod 16 will drive the fixed truss 15 to rotate around the rotating shaft 17, and the fixed truss 15 will drive the multiple upper cultivation tubes 6 to rotate around the rotating shaft 17, thereby separating the upper cultivation tubes 6 from the lower cultivation tubes 7, exposing the glutinous yam in the cultivation tubes, and facilitating the picking of the glutinous yam.

[0057] After harvesting, the cultivation layer 26 needs to be replaced. You only need to pull the isolation mesh cover out of the cultivation tube and then insert a new isolation mesh cover. The isolation mesh cover and the cultivation layer 26 are fixed by extrusion and adhesion to form a finished product. The cultivation layer 26 is squeezed onto the isolation mesh cover by specific mechanical equipment.

[0058] A nutrient solution delivery assembly 4 is installed on the bracket 1, and the nutrient solution delivery assembly 4 is used to deliver the nutrient solution in the storage box 2 to the cultivation assembly 3 for the growth of yam.

[0059] The nutrient solution delivery assembly 4 includes a shunt tube 33 fixedly mounted on the storage box 2 and connected to the storage box 2. The shunt tube 33 is fixedly connected to a plurality of infusion tubes 11 (the infusion tubes 11 are made of a retractable corrugated tube material and can freely change direction and length). Each infusion tube 11 is fixedly mounted with an electric control valve 12, each electric control valve 12 is fixedly mounted with a conduit 22, each conduit 22 is fixedly connected with a plurality of liquid outlet heads, each liquid outlet head penetrates and extends into the interior of the upper cultivation tube 6, and a plurality of biological guide mechanisms matching the corresponding liquid outlet heads are installed in the upper cultivation tube 6.

[0060] The culture medium liquid in the storage box 2 will be evenly diverted into each infusion tube 11 through the shunt tube 33. The electric control valve 12 on each infusion tube 11 will replenish the appropriate nutrient base liquid according to the growth conditions of the glutinous yam. The replenished nutrient base liquid will be injected into the cultivation layer 26 in the cultivation tube through the conduit 22 and the liquid outlet head. The cultivation layer 26 will store the nutrient base liquid for the growth nutrition supply of the glutinous yam.

[0061] The biological guiding mechanism includes a plurality of sponge pads 29 fixedly installed inside the upper cultivation tube 6 and the lower cultivation tube 7, a baffle 30 is fixedly installed between two adjacent sponge pads 29, each baffle 30 is provided with a plurality of hydrophobic holes 31, the sponge pad 29 is located between the cultivation layer 26 and the upper cultivation tube 6 and the lower cultivation tube 7, and a control valve is installed on each liquid outlet head.

[0062] In modern agriculture, the flexibility of agricultural management can be improved by controlling the growth pattern of plants (including lateral growth). For example, the growth efficiency of yam can be improved under a more intensive planting pattern, adapting to different farming methods or equipment, while also facilitating mechanized operations such as fertilizing, watering, and harvesting.

[0063] The nutrient base liquid in the liquid outlet head will enter the sponge pad 29, and the nutrient base liquid will be absorbed into the cultivation layer 26 through the concentration difference between the sponge pad 29 and the cultivation layer 26. At the same time, the concentrations between two adjacent sponge pads 29 are also different. The amount of nutrient base liquid required at the growth end of the glutinous yam is larger and the concentration is higher. Therefore, the concentration difference will be reduced through the hydrophobic holes 31, but the concentration at the end of the glutinous yam will always be greater than the concentration at the front end. Therefore, the glutinous yam will grow to the side with a higher concentration, thereby performing biological guidance.

[0064] The control valve controls the opening and closing of the liquid outlet head, and can control the delivery position of the culture medium liquid according to different growth stages, ensuring that the input position of the culture medium liquid is exactly the growth position of the glutinous yam, avoiding excessive filling of the culture medium liquid into the position where the glutinous yam has not grown, and effectively reducing the loss of the culture medium liquid.

[0065] At the same time, the input of the culture medium liquid is controlled according to the growth stage, so that the culture medium liquid gradually spreads from the starting position of the cultivation component 3 to the end position of the cultivation component 3. As the glutinous yam grows, its root system will grow to places with sufficient nutrients. Therefore, the gradual advancement of the culture medium liquid has a biological guiding effect on the glutinous yam, reduces the impact of physical guidance on the glutinous yam, and effectively improves the growth rate and quality of the glutinous yam.

[0066] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 6-Figure 11 A seedling guide assembly 18 is installed on the bracket 1 to guide the yam seedlings, keep the yam seedlings vertical, and ensure normal lighting for the yam seedlings;

[0067] The seedling guide assembly 18 includes a first universal joint 19 fixedly mounted on the bracket 1, a telescopic rod 20 fixedly mounted on the first universal joint 19, a fixed plate 21 fixedly mounted on the telescopic end of the telescopic rod 20 through a second universal joint, a vertical pole fixedly mounted on the fixed plate 21, and two guide clamps 32 fixedly mounted on the vertical pole.

[0068] During the growth of glutinous yam, shoots will grow first for photosynthesis. Since the initial glutinous yam tubers are placed horizontally, the shoots will grow horizontally after they grow out. At this time, the seedling guide component 18 is adjusted to keep the shoots growing vertically, which is beneficial for the shoots to photosynthesize. At the same time, vertical growth helps the glutinous yam to form a solid trunk and branches, thereby improving the ability to resist wind and pressure and increase the durability of the plant.

[0069] The first universal joint 19 and the second universal joint are both designed with damping, and can remain stable and motionless at any position without being affected by external forces. The function of the telescopic rod 20 is to adjust the height and position of the guide clamp 32 according to the length of the tooth seedling at different growth stages to ensure that the tooth seedling maintains vertical growth. At the same time, the first universal joint 19 and the second universal joint are both designed with damping, and can remain stable and motionless at any position without being affected by external forces, which can provide stable support for the tooth seedling and improve the resistance of the tooth seedling.

[0070] Each guide clip 32 is made of rubber material. The guide clip 32 adopts an arc design with an arc angle of more than 270 degrees. The rubber material can protect the tooth seedlings to prevent damage to the tooth seedlings and can automatically change the size according to the thickness of the tooth seedlings. The purpose of the arc design is to wrap the tooth seedlings inside the guide clip 32 to fix the tooth seedlings and prevent the tooth seedlings from detaching from the guide clip 32.

[0071] A ventilation assembly 5 is installed on the cultivation assembly 3 to ventilate the cultivation assembly 3 and provide oxygen for the growth of the yam.

[0072] The ventilation assembly 5 includes an upper air guide plate fixedly mounted on the upper cultivation tube 6, and also includes a lower air guide plate 28 fixedly mounted on the lower cultivation tube 7. The upper air guide plate and the lower air guide plate 28 are both semicircular in design. An upper ventilation pipe 24 is fixedly mounted on the upper air guide plate, and a lower ventilation pipe 8 is fixedly mounted on the lower air guide plate 28. The upper ventilation pipe 24 and the lower ventilation pipe 8 form a ventilation pipe, and the upper air guide plate and the lower air guide plate 28 form an air guide plate, and the air guide plate is provided with air holes that match the ventilation pipe.

[0073] A plug rod is fixedly installed on the air guide plate, and a plug hole matching the plug rod is opened on the cultivation tube for installing the air guide plate. A dust cover 25 is fixedly installed on the upper ventilation pipe 24 to block external dust and reduce the influence of dust on the growth of the root system of glutinous yam.

[0074] External air will enter the cultivation tube through the ventilation pipe and the holes on the air guide plate, providing oxygen for the growth of glutinous yam. It also has the function of guiding air and ventilation into the cultivation tube, reducing the probability of root rot during the growth of glutinous yam.

[0075] Root aeration can promote root respiration, which can convert stored energy into nutrients needed by plants and promote plant growth. Good ventilation can ensure that the roots get enough oxygen, thereby improving the overall health and growth rate of the plant.

[0076] Good root aeration helps improve soil aeration and water permeability, which can improve soil structure and prevent soil compaction and excessive compaction, allowing water, nutrients and air to enter the root zone more easily. In this way, the roots can absorb water and nutrients more efficiently and promote the healthy growth of plants.

[0077] Root ventilation is not only beneficial to the plants themselves, but also promotes the activity of beneficial microorganisms in the soil. A good root ventilation environment is conducive to the reproduction of beneficial bacteria (such as rhizobia, fungi, etc.), which can help plants absorb more nutrients and improve plant growth quality and disease resistance.

[0078] By keeping the roots ventilated, the accumulation of nutrient solution can be avoided, the root waterlogging can be prevented, and the water can be discharged faster through the cultivation layer 26 to avoid the pressure of excessive liquid accumulation on the root system.

[0079] Advantages of making yam grow horizontally: Yam usually grows vertically, and the underground rhizomes are generally at the base of the main root or on the side branches. By promoting the horizontal growth of yam, multiple side branches or rhizomes can be distributed horizontally, which is not only beneficial for the root system to absorb water and nutrients, but also can improve the uniformity of tuber distribution and avoid poor tuber development caused by vertical growth.

[0080] The specific operation steps of this device are as follows:

[0081] First, the tubers of mature glutinous yam are cut, and then the cut parts of the tubers are coated with a protective layer, and then the tubers are placed horizontally on the lower cultivation tube 7, and then the upper cultivation tube 6 is driven to rotate by the rotating mechanism, so that the upper cultivation tube 6 and the lower cultivation tube 7 are closely attached to complete the installation of the glutinous yam tubers;

[0082] Then, the culture medium in the storage box 2 is evenly distributed into each infusion tube 11 through the shunt tube 33. The electric control valve 12 on each infusion tube 11 will replenish the appropriate nutrient base liquid according to the growth of the glutinous yam. The replenished nutrient base liquid will be injected into the cultivation layer 26 in the cultivation tube through the conduit 22 and the liquid outlet head. The cultivation layer 26 will store the nutrient base liquid for the growth of the glutinous yam.

[0083] The nutrient base liquid in the liquid outlet head will first enter the sponge pad 29 before entering the cultivation layer 26, and the nutrient base liquid will be absorbed into the cultivation layer 26 through the concentration difference between the sponge pad 29 and the cultivation layer 26. At the same time, the concentrations between two adjacent sponge pads 29 are also different. The amount of nutrient base liquid required at the growth end of the glutinous yam is larger and the concentration is higher. Therefore, the concentration difference will be reduced through the hydrophobic holes 31, but the concentration at the end of the glutinous yam will always be greater than the concentration at the front end. Therefore, the glutinous yam will grow to the side with a higher concentration, thereby performing biological guidance.

[0084] At the same time, during the growth process, due to the limitation of the cultivation tube, the glutinous yam will grow horizontally along the inner wall of the cultivation tube. During the growth process, the ventilation component 5 is used to maintain root air circulation and provide sufficient oxygen.

[0085] In the early growth stage, during the growth of glutinous yam, seedlings will first grow out for photosynthesis. Since the initial glutinous yam tubers are placed horizontally, the seedlings will grow horizontally after they grow out. At this time, the seedling guide component 18 is used to keep the seedlings growing vertically, and the height and angle of the seedling guide component 18 are adjusted according to the growth of the seedlings during the growth process.

[0086] Picking: Start the electric push rod 16, and the telescopic end of the electric push rod 16 will extend and retract, which will drive the fixed truss 15 to rotate around the rotating shaft 17. The fixed truss 15 will drive multiple upper cultivation tubes 6 to rotate around the rotating shaft 17, thereby separating the upper cultivation tube 6 from the lower cultivation tube 7, exposing the glutinous yam in the cultivation tube, and facilitating the picking of the glutinous yam.

[0087] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
