Description

Technical Field

[0001] The present invention relates to the technical field of waxy yam cultivation, and particularly to a cultivation device for the horizontal shaping growth of waxy yam. Background Art

[0002] Waxy yam is a kind of yam, which has extremely high medicinal value. The cultivation method of waxy yam is different from that of other plants. It intercepts tubers from mature waxy yams, and forms waxy yams through the development and growth of the tubers. During the growth process, the tubers grow out of stems and leaves.

[0003] When the existing waxy yams are cultivated, they grow vertically downward. After maturity, excavation equipment needs to be used for harvesting. Since the growth length of waxy yams is relatively long, a higher requirement for the excavation depth is needed, which will affect the harvesting efficiency of waxy yams. At the same time, when growing vertically downward, without any obstruction, the tubers of waxy yams will grow towards the place where the nutrient source is sufficient, and most waxy yams will bend. The quality of mature waxy yams is poor. Therefore, the patent with publication number CN215992084U discloses a cultivation device for the horizontal shaping growth of yams, which includes a planting matrix and a guiding extension cover. A support pad is provided at the bottom of the planting matrix. The top of the guiding extension cover is arranged at the bottom of the planting matrix and is interconnected therebetween. At least one guiding tube is provided on the side surface of the guiding extension cover in the same or opposite direction. A limiting cover is connected to the guiding tube, and the limiting cover has various different structural forms.

[0004] Through the cooperation of the planting matrix, the guiding extension cover and the limiting cover, the above-mentioned cultivation device for the horizontal shaping growth of yams can effectively guide and limit the growth of yams, and effectively solve the problems existing in the harvesting of yams, such as low harvesting efficiency, the need for a large amount of manpower and material resources, increased production costs, being easily damaged, reduced economic value, different sizes and specifications, and low commodity rate.

[0005] However, when the above-mentioned cultivation device for the horizontal shaping growth of yams is specifically used, a large amount of nutrient solution is required to meet the growth of yams. Since the root system of yams is relatively short during the growth stage of yams, and the nutrient solution needs to fill the entire limiting cover to ensure that the root system fully absorbs the nutrient solution, this will cause an excess of nutrient solution and lead to the loss of nutrient solution. At the same time, when the nutrient solution is filled, the growth direction of yams completely depends on the limitation of the limiting cover. Through the limiting cover, physical guidance is carried out on yams. During the growth process of yams, being hindered by the limiting cover will affect the growth speed and quality of yams. At the same time, the operation during picking is cumbersome and the picking efficiency is low.

[0006] Therefore, a new cultivation device for the horizontal shaping growth of waxy yams can be adopted to solve the deficiencies of the prior art. Summary of the Invention

[0023] Compared with the existing technology, the advantages of the present invention are as follows:

[0024] 1. When cultivating glutinous yam with the present transverse shaping growth cultivation device for glutinous yam, the growth direction of the glutinous yam is physically guided by setting a cultivation assembly, and the glutinous yam is shaped, so that the glutinous yam grows horizontally in a specific shape along the cultivation assembly, with a shallower growth depth, which is convenient for picking after maturity. At the same time, the horizontal growth is beneficial to the absorption of nutrients, making the absorption of nutrients by each part of the glutinous yam more uniform, which is beneficial to the growth of the glutinous yam.

[0025] 2. When cultivating waxy yams with this horizontal shaping growth cultivation device for waxy yams, a nutrient solution delivery component is set up to deliver nutrient culture solution to the waxy yams in the cultivation component. Moreover, it can automatically control the delivery volume of the culture solution according to the growth stage. In addition, it can also control the delivery position of the culture solution according to different growth stages, ensuring that the input position of the culture solution is exactly the part where the waxy yams grow, avoiding excessive filling of the culture solution in the positions where the waxy yams have not grown yet, and effectively reducing the loss of the culture solution.

[0026] At the same time, the input of the culture solution is controlled according to the growth stage, so that the culture solution gradually spreads from the starting position of the cultivation component to the end position of the cultivation component. Due to the growth of the waxy yams, their roots will grow towards the places where there are sufficient nutrients. Therefore, the gradual progression of the culture solution has a biological guiding effect on the waxy yams, reducing the influence of physical guidance on the waxy yams, and effectively improving the growth rate and quality of the waxy yams.

[0027] 3. When cultivating waxy yams with this horizontal shaping growth cultivation device for waxy yams, an air ventilation component is set up to input oxygen into the cultivation component, providing sufficient oxygen for the growth of the waxy yams. At the same time, it also has the function of guiding air and ventilating in the cultivation component, reducing the probability of root rot during the growth of the waxy yams.

[0028] 4. When cultivating waxy yams with this horizontal shaping growth cultivation device for waxy yams, a seedling guiding component is set up to guide the sprouts of the waxy yams, ensuring that the sprouts grow vertically. This is beneficial for the sprouts to carry out photosynthesis. At the same time, vertical growth helps the waxy yams form a solid main stem and branches, thereby improving the abilities such as wind resistance and pressure resistance, and increasing the durability of the plants.

[0029] 5. When harvesting waxy yams with this horizontal shaping growth cultivation device for waxy yams, a rotating mechanism is set up to drive the upper cultivation pipe to rotate, separating the upper cultivation pipe from the lower cultivation pipe, and the upper partition net and the lower partition net will also be separated. At this time, the waxy yams located between the upper partition net and the lower partition net will be directly exposed, making the harvesting more convenient and improving the harvesting efficiency.

[0030] In summary, the present invention not only makes the waxy yams grow horizontally through physical guidance, but also conducts biological guidance on them, enabling the waxy yams to grow horizontally automatically during growth, reducing the adverse impact of physical guidance on the growth of the waxy yams, promoting the growth of the waxy yams. In addition, it can also automatically open the upper cultivation pipe to expose the waxy yams in the cultivation component, with convenient operation and improved harvesting efficiency of the waxy yams.

Detailed implementation mode

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0047] Embodiment 1: Refer to Figures 1 - 7 , Figures 9 - 13 , a horizontal shaping growth cultivation device for glutinous yam, including a support 1, and also including a storage box 2, in which a culture medium solution is stored, and it is necessary to adaptively change the concentration and nutrients of the culture medium solution at different growth stages;

[0048] A cultivation component 3 is installed on the support 1 to cultivate yam and guide the yam to 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, facilitate picking after maturity, and at the same time, the horizontal growth is beneficial to the absorption of nutrients, making each part of the glutinous yam absorb more evenly and being beneficial to the growth of the glutinous yam.

[0049] The cultivation component 3 includes a plurality of upper cultivation pipes 6 and a plurality of lower cultivation pipes 7. Each lower cultivation pipe 7 is fixedly connected to the support 1. An upper partition net 9 and a lower partition net 10 are respectively slidably installed in each upper cultivation pipe 6 and each lower cultivation pipe 7. A cultivation layer 26 is filled between each upper partition net 9 and the corresponding upper cultivation pipe 6 and between each lower partition net 10 and the corresponding lower cultivation pipe 7.

[0050] Both the upper partition net 9 and the lower partition net 10 are composed of arc-shaped wire meshes. The upper partition net 9 and the lower partition net 10 form a partition net cover, and the mesh size of which is larger than the root diameter of the glutinous yam, so that the roots can more easily insert into the cultivation layer 26 to absorb nutrients. At the same time, the mesh size also needs to meet the requirement that the particles of the cultivation layer 26 will not fall off.

[0051] The upper cultivation pipe 6 and the lower cultivation pipe 7 form a cultivation pipe. The diameter of the cultivation pipe is slightly larger than the diameter of the tuber of the waxy yam, preventing the cultivation pipe from generating a large resistance to the growth of the tuber and being conducive to the normal growth of the waxy yam. The diameter difference between the diameter of the waxy yam tuber and the diameter of the cultivation pipe is controlled between 3 and 5 millimeters.

[0052] The cultivation layer 26 is composed of a variety of fluffy soilless cultivation substances, including coconut coir, perlite, vermiculite, and ceramsite porous particulate substances. These substances have good air permeability, water retention, and water conductivity respectively, and can smoothly conduct the nutrient base solution to the root position of the waxy yam to ensure the absorption of the nutrient base solution by the roots. At the same time, high air permeability can effectively reduce the probability of root rot.

[0053] A plurality of crossbars are fixedly installed on the bracket 1, and two insertion cylinders 13 are fixedly installed on each crossbar. Two insertion cones 23 are fixedly installed at the bottom of each lower cultivation pipe 7, and each insertion cone 23 is respectively inserted into the corresponding insertion cylinder 13.

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

[0055] A rotating mechanism is installed between the bracket 1 and a plurality of upper cultivation pipes 6. 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 pipe 6 is fixedly connected to the fixed truss 15, and an electric push rod 16 is rotatably installed on the fixed frame 14. The telescopic end of the electric push rod 16 is rotatably connected to the fixed truss 15.

[0056] When the telescopic end of the electric push rod 16 expands and contracts, it will drive the fixed truss 15 to rotate around the rotating shaft 17, and the fixed truss 15 will drive a plurality of upper cultivation pipes 6 to rotate around the rotating shaft 17, so that the upper cultivation pipe 6 is separated from the lower cultivation pipe 7, exposing the waxy yam in the cultivation pipe for easy picking of the waxy yam.

[0057] After picking, the cultivation layer 26 needs to be replaced. Just pull out the partition net cover from the cultivation pipe, and then insert a new partition net cover. The partition net cover and the cultivation layer 26 are fixed by extrusion adhesion. It is a finished product, and the cultivation layer 26 is extruded onto the partition net cover by specific mechanical equipment.

[0058] A nutrient solution delivery component 4 is installed on the bracket 1. The nutrient solution delivery component 4 is used to deliver the nutrient solution in the storage tank 2 to the cultivation component 3 for the growth of the yam.

[0059] The nutrient solution delivery assembly 4 includes a shunt pipe 33 fixedly installed on and communicating with the storage tank 2. A plurality of infusion pipes 11 are fixedly communicated with the shunt pipe 33 (the infusion pipes 11 are made of telescopic corrugated pipe material and can freely change directions and lengths). An electric control valve 12 is fixedly installed on each infusion pipe 11. A conduit 22 is fixedly installed on each electric control valve 12. A plurality of liquid outlet heads are fixedly communicated with each conduit 22. Each liquid outlet head penetrates and extends into the upper cultivation pipe 6. A plurality of biological guiding mechanisms cooperating with the corresponding liquid outlet heads are installed in the upper cultivation pipe 6.

[0060] The culture medium liquid in the storage tank 2 will be evenly shunted into each infusion pipe 11 through the shunt pipe 33. The electric control valve 12 on each infusion pipe 11 will supply appropriate culture medium liquid according to the growth situation of the glutinous yam. The supplied culture medium liquid will be injected into the cultivation layer 26 in the cultivation pipe through the conduit 22 and the liquid outlet heads. The cultivation layer 26 will store the culture medium 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 pipe 6 and the lower cultivation pipe 7. A retaining strip 30 is fixedly installed between two adjacent sponge pads 29. A plurality of hydrophobic holes 31 are formed in each retaining strip 30. The sponge pads 29 are located between the cultivation layer 26 and the upper cultivation pipe 6 and the lower cultivation pipe 7. A control valve is installed on each liquid outlet head.

[0062] In modern agriculture, by controlling the plant growth mode (including horizontal growth), the flexibility of agricultural management can be improved. For example, the growth efficiency of yams can be increased under a relatively dense planting mode, adapting to different tillage methods or equipment, and at the same time, it is also convenient for mechanized operations such as fertilizing, watering, and harvesting.

[0063] The culture medium liquid in the liquid outlet head will enter the sponge pad 29. The culture medium liquid is sucked 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 culture medium 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 higher than that at the front end. Therefore, the glutinous yam will grow towards the side with a higher concentration to conduct biological guidance in this way.

[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 to ensure that the input position of the culture medium liquid is exactly the part where the glutinous yam grows, avoiding excessive filling of the culture medium liquid to the position where the glutinous yam has not grown, and effectively reducing the loss of the culture medium liquid.

[0065] Meanwhile, the input of the culture medium solution is controlled according to the growth stage, so that the culture medium solution gradually spreads from the starting position of the cultivation component 3 to the end position of the cultivation component 3. Due to the growth of the waxy yam, its roots will grow towards the place where there is sufficient nutrients. Therefore, the gradual progression of the culture medium solution has a biological guiding effect on the waxy yam, reduces the influence of physical guidance on the waxy yam, and effectively improves the growth rate and quality of the waxy yam.

[0066] Example 2: The difference between this example and the technical solution of Example 1 lies in that: referring to Figures 6 - 11 , a seedling cultivation guiding component 18 is installed on the support 1, which is used to guide the yam seedlings, keep the yam seedlings vertical, and ensure the normal lighting of the yam seedlings;

[0067] The seedling cultivation guiding component 18 includes a first universal joint 19 fixedly installed on the support 1. A telescopic rod 20 is fixedly installed on the first universal joint 19. The telescopic end of the telescopic rod 20 is fixedly installed with a fixed disk 21 through a second universal joint. A vertical rod is fixedly installed on the fixed disk 21, and two guiding clips 32 are fixedly installed on the vertical rod.

[0068] During the growth process of the waxy yam, tooth seedlings will grow first for photosynthesis. Since the initial waxy yam tuber is placed horizontally, the tooth seedlings grow horizontally after growing out. At this time, the seedling cultivation guiding component 18 is adjusted to keep the tooth seedlings growing vertically, which is beneficial to the photosynthesis of the tooth seedlings. At the same time, vertical growth helps the waxy yam to form a solid main stem and branches, thereby improving the wind resistance, compressive resistance and other abilities, and increasing the durability of the plant.

[0069] Both the first universal joint 19 and the second universal joint are designed with damping and can remain stable at any position without the action of external forces. The function of the telescopic rod 20 is to adjust the height and position of the guiding clip 32 according to the length of the tooth seedlings at different growth stages to ensure that the tooth seedlings grow vertically. At the same time, both the first universal joint 19 and the second universal joint are designed with damping and can remain stable at any position without the action of external forces, which can provide stable support for the tooth seedlings and improve the resistance of the tooth seedlings.

[0070] Each guiding clip 32 is made of rubber material. The guiding clip 32 is designed in an arc shape, and the radian of the arc exceeds 270 degrees. The rubber material can protect the tooth seedlings from damage and can automatically change the size according to the thickness of the tooth seedlings. The purpose of the radian design is to wrap the tooth seedlings inside the guiding clip 32 to fix the tooth seedlings and prevent the tooth seedlings from detaching from the guiding clip 32.

[0071] An air venting component 5 is installed on the cultivation component 3, which is used to ventilate the cultivation component 3 and provide oxygen for the growth of the yam.

[0072] The ventilation component 5 includes an upper air guide disc fixedly installed on the upper cultivation pipe 6 by clamping, and also includes a lower air guide disc 28 fixedly installed on the lower cultivation pipe 7 by clamping. Both the upper air guide disc and the lower air guide disc 28 are semi-circular in design. An upper ventilation pipe 24 is fixedly installed on the upper air guide disc, and a lower ventilation pipe 8 is fixedly installed on the lower air guide disc 28. The upper ventilation pipe 24 and the lower ventilation pipe 8 form a ventilation pipe, and the upper air guide disc and the lower air guide disc 28 form an air guide disc. Air holes are provided on the air guide disc to cooperate with the ventilation pipe.

[0073] Insertion rods are fixedly installed on the air guide disc, and insertion holes are provided on the cultivation pipe to cooperate with the insertion rods for installing the air guide disc. A dust-proof cover 25 is fixedly installed on the upper ventilation pipe 24 to block external dust and reduce the impact of dust on the growth of the roots of glutinous yams.

[0074] External air will enter the cultivation pipe through the ventilation pipe and the air holes on the air guide disc, providing oxygen for the growth of glutinous yams, and at the same time also having the function of guiding air and ventilating into the cultivation pipe, reducing the probability of root rot during the growth of glutinous yams.

[0075] Root ventilation can promote root respiration. Root respiration can convert the stored energy into nutrients required by plants, promoting plant growth. Good ventilation can ensure that the roots obtain sufficient oxygen, thereby improving the overall health and growth rate of plants.

[0076] Good root ventilation helps to improve the air permeability and water permeability of the soil, which can improve the soil structure, prevent soil compaction and over-compaction, so that water, nutrients and air can more easily enter the root zone. In this way, the roots can absorb water and nutrients more efficiently, promoting 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 bacterial groups (such as rhizobia, fungi, etc.). These microorganisms can help plants absorb more nutrients, improving the growth quality and disease resistance of plants.

[0078] By maintaining root ventilation, the accumulation of nutrient base liquid can be avoided, the phenomenon of root waterlogging can be prevented, and water can be discharged more quickly through the cultivation layer 26, avoiding the compression of the roots caused by excessive liquid accumulation.

[0079] Advantages of making the yam grow horizontally: The growth of yams usually occurs longitudinally. The rhizomes of the underground part are generally at the main root base or side branches. By promoting the horizontal growth of yams, multiple lateral branches or rhizomes can be made to distribute horizontally. This not only facilitates the roots to absorb water and nutrients, but also improves the uniformity of the distribution of tubers, avoiding poor development of tubers caused by longitudinal growth.

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

[0081] First, cut the tubers from mature waxy yams. Then, apply a protective layer to the cut parts of the tubers. Next, place the tubers horizontally on the lower cultivation pipe 7. Then, drive the upper cultivation pipe 6 to rotate through the rotating mechanism so that the upper cultivation pipe 6 is in close contact with the lower cultivation pipe 7, completing the installation of the waxy yam tubers.

[0082] Then, the culture medium liquid in the storage tank 2 is evenly distributed into each infusion pipe 11 through the shunt pipe 33. The electric control valve 12 on each infusion pipe 11 will supply an appropriate amount of nutrient medium liquid according to the growth situation of the waxy yams. The supplied nutrient medium liquid will be injected into the cultivation layer 26 in the cultivation pipe through the conduit 22 and the liquid outlet head. The cultivation layer 26 will store the nutrient medium liquid for the growth nutrition supply of the waxy yams.

[0083] Before the nutrient medium liquid in the liquid outlet head enters the cultivation layer 26, it will first enter the sponge pad 29. The nutrient medium liquid is sucked 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 adjacent sponge pads 29 are also different. The amount of nutrient medium liquid required at the growth end of the waxy yam is larger and the concentration is higher. Therefore, the concentration difference is reduced through the hydrophobic holes 31, but the concentration at the end of the waxy yam is always higher than that at the front end. Therefore, the waxy yam will grow towards the side with a higher concentration to conduct biological orientation in this way.

[0084] Meanwhile, during the growth process, due to the limitation of the cultivation pipe, the waxy yam will grow horizontally along the inner wall of the cultivation pipe. During the growth process, the ventilation component 5 is used to keep the air circulation of the roots and provide sufficient oxygen.

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

[0086] Harvesting: Start the electric push rod 16. The telescopic end of the electric push rod 16 will drive the fixed truss 15 to rotate around the rotating shaft 17. The fixed truss 15 will drive multiple upper cultivation pipes 6 to rotate around the rotating shaft 17, so that the upper cultivation pipe 6 is separated from the lower cultivation pipe 7, exposing the waxy yams in the cultivation pipe for easy harvesting of the waxy yams.

[0087] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
