A cultivating device applied to wheat breeding

Abstract

This invention relates to the field of seed breeding, and in particular to a breeding device for wheat breeding, comprising a breeding chamber, a breeding unit set on the breeding chamber, and a seed dispensing unit set on the breeding unit. The invention uses a combination of a fixed plate and a pusher plate to simultaneously feed wheat seeds into a seed storage hopper. The pusher plate, pushed back and forth, under the influence of gravity, evenly distributes single or multiple wheat seeds onto the feeding holes, causing the seeds to fall into corresponding breeding pots, resulting in consistent seedling density. Simultaneously, the synergistic effect of the spiral ridges and the air gap layer fundamentally alters root growth behavior. When roots grow to the wall of the breeding pot, they encounter the triangular cross-section of the spiral ridges, preventing them from continuing to spiral horizontally along the wall. This guides the roots to grow obliquely along the spiral ridges, increasing the probability of roots penetrating the substrate and returning to the interior, forming a robust root system with well-developed fibrous roots and moderate root length, shortening the post-transplant recovery period, and improving the survival rate.

Description

Technical Field

[0001] This invention relates to the field of seed breeding, and in particular to a breeding device for wheat breeding. Background Technology

[0002] Wheat is one of my country's main food crops, and breeding work is of great significance to ensuring food security. Currently, wheat seed breeding usually involves directly scattering seeds into cultivation containers and cultivating them in greenhouses. However, in large-scale cultivation, direct scattering of seeds can easily lead to uneven distribution of seeds in the containers, resulting in local accumulation and gaps, and causing large differences in seedling density. This unevenness can cause inconsistent competition among plants, with weak seedlings mixed with strong ones. At the same time, locally accumulated seeds have entangled roots that are difficult to separate during germination. While manually placing seeds one by one can ensure even distribution, it greatly increases the workload and reduces efficiency. Moreover, when wheat is cultivated in plastic seedling pots or plug trays, the limited space and smooth sidewalls cause roots to spiral along the walls, forming root pads and excessive root growth. These deformed root systems have difficulty adapting to the soil environment after transplanting to the field, and their absorption function recovers slowly. Summary of the Invention

[0003] In view of the problems in the above-mentioned or existing technologies, such as the uneven distribution of seeds in the container when directly scattering seeds during large-scale cultivation, resulting in localized seed accumulation and root entanglement during germination, making them difficult to separate, and the problem that when wheat is cultivated in plastic seedling pots or plug trays, the roots grow spirally along the wall after encountering the wall due to the limited space and smooth sidewalls, forming root pads and excessive root growth, this invention is proposed.

[0007] As a preferred embodiment of the present invention applied to the cultivation device for wheat breeding, the inner wall of the breeding pot is provided with a spiral protrusion, the cross section of the spiral protrusion is triangular, and it is distributed in a spiral line from bottom to top along the side wall of the breeding pot.

[0008] As a preferred embodiment of the present invention applied to the cultivation device for wheat breeding, the air gap component includes an air gap plate disposed below the breeding pot, a protrusion disposed between the breeding pot and the air gap plate, the gap between the breeding pot and the air gap plate being configured as an air gap layer, and a root guiding microgroove disposed on the protrusion.

[0009] As a preferred embodiment of the cultivation device of the present invention applied to wheat breeding, wherein: the air pipe is connected to the air gap layer, and one end of the air pipe penetrates through the inner wall of the cultivation chamber to the outside.

[0010] As a preferred embodiment of the present invention applied to the cultivation device for wheat breeding, the hydrophobic component includes a water collection box disposed at the bottom of the cultivation chamber, a connecting pipe 1 disposed on the breeding tray and communicating with the inside of the breeding tray, a connecting pipe 2 disposed on the connecting pipe 1 and communicating with the connecting pipe 1, and a plug disposed on the connecting pipe 1 and the connecting pipe 2; the lowest connecting pipe 1 communicates with the inside of the water collection box, and a water pump and an atomizing nozzle are disposed in the water collection box.

[0011] As a preferred embodiment of the cultivation device of the present invention applied to wheat breeding, the breeding tray is provided with a support block that matches the positioning block.

[0012] As a preferred embodiment of the present invention applied to a breeding device for wheat breeding, wherein: a fixed block is provided on the seed storage hopper to cooperate with the seed dispensing component; the seed dispensing component includes a seed release control component provided on the seed storage hopper, a sliding push block slidably provided on the seed storage hopper, and a push plate provided on the seed storage hopper to cooperate with the sliding push block.

[0013] As a preferred embodiment of the present invention applied to a wheat breeding device, the seed dispensing control component includes: a fixed plate inclinedly disposed on the seed storage hopper; a movable plate slidably disposed on the seed storage hopper and extending through the seed storage hopper to the outside at one end; an abutment block disposed on the movable plate; a handle disposed on the abutment block; a guide shaft disposed on the seed storage hopper and slidably connected to the abutment block; and a support spring whose two ends are fixedly connected to the fixed block and the abutment block, respectively; a limit block is provided on the push plate; a guide groove that matches the limit block is also provided on the seed storage hopper; the guide trajectory of the guide groove conforms to the inclination angle of the fixed plate; and a sliding cavity that matches the push plate is provided on the sliding push block.

[0014] As a preferred embodiment of the present invention applied to the cultivation device for wheat breeding, the following is provided: both the fixed plate and the movable plate are provided with material discharge holes, and the material discharge holes on the fixed plate correspond one-to-one with the breeding pots; in the non-discharging state, the material discharge holes on the fixed plate and the movable plate are staggered; in the discharging state, the material discharge holes on the fixed plate and the movable plate overlap.

[0015] The beneficial effects of the cultivation device of the present invention applied to wheat breeding are as follows: The present invention uses the cooperation of a fixed plate and a push plate to put wheat seeds into the seed storage hopper at one time. With the push plate being pushed back and forth, under the action of gravity, single or fixed-size wheat seeds are evenly distributed on the feeding holes. By pulling the movable plate, the upper and lower feeding holes are made to overlap, so that the wheat seeds in the feeding holes fall into the corresponding breeding pots, resulting in consistent seedling density and balanced competition among plants.

[0016] Simultaneously, the synergistic effect of the spiral ridges and air gaps fundamentally alters root growth behavior. When roots grow to the wall of the breeding pot, they encounter the triangular cross-section of the spiral ridges, preventing them from continuing to spiral horizontally along the wall. This guides the roots to grow obliquely along the spiral ridges, increasing the probability of roots penetrating the substrate and returning to the interior. In conjunction with the air gaps, when the root tip grows to the bottom air gaps, the growth point is suppressed due to reduced humidity and direct contact with oxygen, triggering the germination of lateral roots inside the substrate. This concentrates the roots inside the substrate, reducing adhesion to the container wall, eliminating root pads and spiral roots along the wall, and forming a robust root system with well-developed fibrous roots and moderate root length. This shortens the seedling recovery period after transplanting and improves the survival rate. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example 1, referring to Figure 1 , Figure 2 ,as well as Figure 6 This is the first embodiment of the present invention. This embodiment provides a cultivation device for wheat breeding, which includes a cultivation chamber 1, a cultivation unit 2 disposed on the cultivation chamber 1, and a seeding unit 3 disposed on the cultivation unit 2. The cultivation chamber 1 is equipped with a light system and a temperature and humidity control system to serve as a greenhouse and provide a suitable environment for cultivating wheat seeds. The cultivation unit 2 is used to provide the nutrients required for the growth of wheat seeds. The seeding unit 3 is used to quickly distribute wheat seeds to corresponding positions on the cultivation unit 2 when cultivating on a large scale.

[0028] The cultivation unit 2 includes a movable frame 21 mounted on the cultivation chamber 1, a breeding component 22 mounted on the movable frame 21, an atomizing nozzle 23 mounted on the cultivation chamber 1, and a hydrophobic component 24 mounted on the movable frame 21 to cooperate with the breeding component 22. The movable frame 21 is used to support and transport the breeding component 22. The movable frame 21 is equipped with locking wheels to facilitate movement. The breeding component 22 is used to carry the substrate and provide the nutrients required for wheat seed growth. The atomizing nozzle 23 is used to spray water and nutrient solution onto the breeding component 22. The hydrophobic component 24 is used to provide liquid to the atomizing nozzle 23 and to maintain the humidity of the substrate on the breeding component 22 within a certain range to prevent the substrate from becoming too wet and affecting wheat seed cultivation.

[0029] The seed-separating unit 3 includes a seed storage hopper 31 mounted on a movable frame 21, a seed-separating component 32 mounted on the seed storage hopper 31, and a positioning block 33 mounted on the seed storage hopper 31 to cooperate with the movable frame 21. The seed storage hopper 31 is used to receive and carry wheat seeds to be cultivated, the seed-separating component 32 is used to arrange the wheat seeds, and the positioning block 33 is used to make the wheat seeds fall evenly into the corresponding area on the seed-separating component 22.

[0030] In summary, during breeding, the door of the cultivation chamber 1 is first opened, and the breeding component 22 is transferred out using the movable frame 21. At this time, the substrate is filled onto the breeding component 22. The seeding unit 3 is then connected to the breeding component 22 using the positioning block 33. The wheat seeds are then placed in the seed storage hopper 31, and the wheat seeds are arranged using the seeding component 32. The arranged wheat seeds are then placed into the corresponding positions on the breeding component 22 for sowing. After the sowing activity is completed, the breeding component 22 is sent back into the cultivation chamber 1 using the movable frame 21. At this time, the atomizing nozzle 23 sprays nutrient solution onto the breeding component 22, and excess nutrient solution is discharged from the breeding component 22 through the hydrophobic component 24.

[0031] Example 2, referring to Figures 1-1, is the second embodiment of the present invention. Unlike the previous embodiment, it provides a specific structure for the cultivation unit 2 in a cultivation device applied to wheat breeding. Compared to Example 1, the breeding component 22 further includes multiple sets of breeding trays 221 mounted on a movable frame 21, breeding pots 222 mounted on the breeding trays 221, air gap components 223 at the bottom of the breeding pots 222, and ventilation pipes 224 mounted on the breeding trays 221. The breeding trays 221 support the breeding pots 222. The breeding pots 222 have multiple grids filled with a substrate. The air gap components 223 create air gaps at the bottom of the breeding pots 222. When wheat roots come into contact with these gaps, the reduced humidity and direct contact with oxygen inhibit the growth of lateral roots in the substrate, preventing excessive root growth. The ventilation pipes 224 connect to the air gap components 223 to introduce air into them.

[0032] The mobile frame 21 is provided with a connecting slide 211, and the breeding tray 221 is provided with a connecting slider 2212 that cooperates with the connecting slide 211. Through the cooperation of the connecting slide 211 and the connecting slider 2212, the breeding component 22 can be installed and disassembled on the mobile frame 21, and the number of breeding components 22 can be increased or decreased according to the number of breeding.

[0033] The breeding pot 222 has a spiral ridge 2221 on its inner wall. The spiral ridge 2221 has a triangular cross section and is distributed in a spiral line from bottom to top along the side wall of the breeding pot 222. The spiral ridge 2221 is used to break the smooth inner wall of the breeding pot 222, block the roots growing towards the inner wall of the breeding pot 222, prevent the roots from continuing to spiral horizontally along the wall, and guide the roots to grow into the interior of the substrate.

[0034] The air gap component 223 includes an air gap plate 2231 disposed below the breeding pot 222, a protrusion 2232 disposed between the breeding pot 222 and the air gap plate 2231, the gap between the breeding pot 222 and the air gap plate 2231 being configured as an air gap layer 2233, and a root guiding microgroove 2234 disposed on the protrusion 2232. The air gap plate 2231 is used to support the protrusion 2232, and the protrusion 2232 forms an air gap layer 2233 with intersecting grooves between the breeding pot 222 and the air gap plate 2231. With the help of the ventilation pipe 224, air flows in the air gap layer 2233 to prevent excessive growth of the taproot and guide the roots to extend horizontally. The root guiding microgroove 2234 is configured in a cross shape to provide physical guidance for the primary roots, so that the roots are distributed in an orderly manner along a preset direction and avoid tangling.

[0035] The ventilation pipe 224 is connected to the air gap layer 2233. One end of the ventilation pipe 224 penetrates the inner wall of the cultivation chamber 1 to the outside. The ventilation pipe 224 introduces air into the air gap layer 2233 through this arrangement, maintains the air flow in the air gap layer 2233, and ensures that the air trimming effect is continuously effective.

[0036] The hydrophobic component 24 includes a water collection box 241 located at the bottom of the cultivation chamber 1, a first connecting pipe 242 located on the breeding tray 221 and communicating with the inside of the breeding tray 221, a second connecting pipe 243 located on the first connecting pipe 242 and communicating with the first connecting pipe 242, and a connector 244 located on the first connecting pipe 242 and the second connecting pipe 243. The water collection box 241 is used to store and collect nutrient solution, the first connecting pipe 242 is used to collect excess nutrient solution in the breeding tray 222 and prevent liquid accumulation by introducing the liquid into the water collection box 241, and the second connecting pipe 243 is used to connect adjacent water collection boxes 241 through the connector 244 to facilitate the drainage of liquid accumulated in the breeding tray 221.

[0037] The bottom connecting pipe 242 is connected to the inside of the water collection box 241. The water collection box 241 is equipped with a water pump connected to the atomizing nozzle 23. The water pump sprays the liquid in the water collection box 241 through the atomizing nozzle 23 to the breeding pot 222 through the filter device. In this way, the liquid can be recycled.

[0038] The rest of the structure is the same as in Example 1.

[0039] In summary, when the moving frame 21 delivers the breeding component 22 containing wheat seeds into the cultivation chamber 1, the atomizing nozzle 23 uses a water pump to draw nutrient solution from the water collection box 241 and spray it onto the breeding pot 222. Combined with the greenhouse environment of the cultivation chamber 1, when the wheat seed roots grow in the substrate and reach the wall of the breeding pot 222, the spiral ridges 2221 prevent the roots from continuing to spiral horizontally along the wall of the breeding pot 222. At the same time, the roots are guided to grow into the substrate. When the roots grow downward into the air gap layer 2233, the air flow in the air gap layer 2233 is low and the oxygen content is high. At this time, the root growth point is inhibited, triggering the lateral roots to germinate inside the substrate. The newly grown roots extend horizontally under the guidance of the grooves on the air gap layer 2233, forming a robust, flattened root zone structure.

[0040] Example 3, referring to Figure 1 - Figure 7 This is the second embodiment of the present invention. Unlike the previous embodiment, it provides a specific structure for the seeding unit 3 in a wheat breeding apparatus. Compared to embodiment 2, the breeding tray 221 is further provided with a support block 2211 that cooperates with the positioning block 33. The support block 2211, in conjunction with the positioning block 33, positions and supports the seeding unit 3 on the breeding tray 221. When the support block 2211 and the positioning block 33 are fully aligned, the position of the wheat seeds falling on the seeding component 32 corresponds to that of the breeding tray 222.

[0041] Among them, the seed storage hopper 31 is provided with a fixing block 312 that cooperates with the seed dispensing component 32. The fixing block 312 plays a supporting and abutting role for the seed dispensing component 32.

[0042] The seeding assembly 32 includes a seeding control component 321 disposed on the seed storage hopper 31, a sliding pusher block 322 slidably disposed on the seed storage hopper 31, and a pusher plate 323 disposed on the seed storage hopper 31 to cooperate with the sliding pusher block 322; wherein, the sliding pusher block 322 is used to drive the pusher plate 323 to move on the seeding control component 321, cooperate with the seeding control component 321 to arrange the wheat seeds, and then the seeding control component 321 puts the arranged wheat seeds into the breeding pot 222.

[0043] The seeding control component 321 includes a fixed plate 3211 inclinedly disposed on the seed storage hopper 31, a movable plate 3212 slidably disposed on the seed storage hopper 31 and extending through the seed storage hopper 31 to the outside at one end, an abutment block 3213 disposed on the movable plate 3212, a handle 3214 disposed on the abutment block 3213, a guide shaft 3215 disposed on the seed storage hopper 31 and slidably connected to the abutment block 3213, and two ends fixedly connected to the fixed plate 312 and the abutment block 3213 respectively. The supporting spring 3216 is connected; wherein, the fixed plate 3211 is used to cooperate with the seed storage hopper 31 to carry the wheat seeds put in, and the handle 3214 pulls the movable plate 3212 through the abutment block 3213, causing the movable plate 3212 to slide relative to the fixed plate 3211, controlling the wheat seeds arranged on the fixed plate 3211 to fall down, and then through the relative movement of the abutment block 3213 and the fixed block 312, the force generated by the supporting spring 3216 is squeezed, causing the movable plate 3212 to return to its original position.

[0044] A limiting block 3231 is provided on the push plate 323, and a guide groove 311 that cooperates with the limiting block 3231 is also provided on the seed storage hopper 31. The guide trajectory of the guide groove 311 is in line with the tilt angle of the fixed plate 3211. With this arrangement, the push plate 323 moves back and forth along the surface of the fixed plate 3211, pushing the wheat seeds to the corresponding position on the fixed plate 3211. The remaining seeds gather downwards as the push plate 323 slides down, in conjunction with the effect of gravity.

[0045] The sliding push block 322 is provided with a sliding cavity 3221 that cooperates with the push plate 323. The sliding cavity 3221 is used to cooperate with the height change generated when the push plate 323 slides on the fixed plate 3211.

[0046] Both the fixed plate 3211 and the movable plate 3212 are provided with a discharge hole 34. The discharge hole 34 on the fixed plate 3211 corresponds one-to-one with the breeding pot 222. The discharge hole 34 is used to hold wheat seeds. When the wheat seeds enter the discharge hole 34, the push plate 323 can no longer push the wheat seeds in the discharge hole 34.

[0047] In the non-feeding state, the dropping holes 34 on the fixed plate 3211 and the movable plate 3212 are staggered; as the push plate 323 pushes back and forth, the wheat seeds will gradually fill all the dropping holes 34 on the fixed plate 3211, and the excess wheat seeds will continue to fall into the bottom of the seed storage hopper 31 under the action of the push plate 323 and gravity.

[0048] In the feeding state, the dropping holes 34 on the fixed plate 3211 and the movable plate 3212 overlap, so that the wheat seeds in the dropping holes 34 fall into the corresponding breeding pot 222, completing the sowing.

[0049] The rest of the structure is the same as in Example 2.

[0050] In summary, when the seeding unit 3 is mounted on the seed tray 221 via the cooperation of the positioning block 33 and the support block 2211, the discharge hole 34 on the fixed plate 3211 corresponds to the seed tray 222. The push plate 323 is then positioned at the bottom of the seed storage hopper 31, and wheat seeds are added to the hopper. The sliding push block 322 is pushed back and forth, causing the push plate 323 to move back and forth on the fixed plate 3211, pushing the wheat seeds to move on the fixed plate 3211. When the moving wheat seeds enter the discharge hole 34 on the fixed plate 3211, the push plate 323, due to its contact with the surface of the fixed plate 3211, cannot carry the wheat seeds out of the discharge hole 34. The remaining wheat seeds continue to move back and forth on the fixed plate 3211 under the push of the push plate 323 and the force of gravity, until the wheat seeds fill the fixed plate 3211. When the feeding hole 34 on plate 11 is fully filled, pull the push plate 323 to the lowest point of the fixed plate 3211. At this time, the remaining wheat seeds gather on one side of the push plate 323 by gravity. Then, pull the handle 3214 to drive the movable plate 3212 to slide relative to the fixed plate 3211. When pulled to the end, the feeding holes 34 on the fixed plate 3211 and the movable plate 3212 coincide. At this time, the wheat seeds in the feeding holes 34 fall into the corresponding breeding pot 222 below, completing the sowing. Then, release the handle 3214. Under the force generated by the release of the support spring 3216, the movable plate 3212 returns to its original position. At this time, the feeding holes 34 on the fixed plate 3211 and the movable plate 3212 are misaligned. At this time, the entire sowing unit 3 can be transferred from the breeding component 22 for the next round of sowing.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
