Description

Technical Field

[0001] This utility model belongs to the field of agricultural seedling technology, specifically relating to a hybrid seed seedling raising device. Background Technology

[0002] Hybrid breeding is the core approach to cultivating new plant varieties. For precious ornamental plants such as Paeonia, there are numerous hybridization combinations, but the number of seeds obtained from each combination is often small. The currently widely used direct seeding method has many drawbacks: First, sowing easily leads to the mixing of seeds from different hybrid combinations, causing the entire breeding experiment to fail and resulting in irreparable losses; second, weeding and fertilization during field management can easily damage delicate seedlings; third, seedlings need to be transplanted after one to two years of growth, and the traditional seedling lifting process can damage the seedling root system, resulting in a long recovery period after transplanting, low survival rate, and even the death of precious hybrid offspring.

[0003] While various seedling boxes or devices exist in the existing technology, none have provided effective solutions for the needs of "preventing mixing, facilitating management, and non-destructive transplanting" in hybridization breeding. Therefore, there is an urgent need in this field for a specialized seedling device that can achieve precise sowing of seedlings in different combinations, facilitate centralized management, and enable non-destructive transplanting. Utility Model Content

[0004] To address the aforementioned technical problems, this invention provides a hybrid seedling raising device with a reasonable structure and convenient operation. This device effectively prevents mixing between different hybrid combinations through physical isolation and achieves root-free transplanting. After transplanting, no acclimatization period is required, thus significantly improving the efficiency and success rate of hybridization breeding. The technical solution adopted by this utility model is as follows: a hybrid seed seedling raising device, including a support frame, in which at least two seedling box units are arranged. The seedling box units are stacked on the support frame in the length and height directions by connecting blocks. The connecting blocks in the height direction are fixed to the support frame, and the connecting blocks in the length direction are arranged at the lateral connection of two adjacent seedling box units and fixed to the lateral guardrail of the support frame, thereby completing the installation and fixing of one or more seedling box units on the support frame. The seedling box unit includes a rectangular frame and a bottom plate arranged in the rectangular frame. The bottom plate is provided with ventilation holes. The seedling box unit is used to accommodate strip-shaped seedlings. The strip-shaped seedlings are formed by linearly connecting multiple independent seedling pots for holding seeds through easy-tear connecting parts.

[0005] Specifically, the seedling pot has an inverted frustum-shaped opening structure that is larger at the top and smaller at the bottom, and a pre-set tear line is provided at the bottom for the roots to pass through.

[0006] Specifically, the preset tear line is either in the shape of a star or in a ring.

[0007] Specifically, the lower half of the inner side of the left and right side plates of the seedling box unit is symmetrically provided with guide grooves along the length direction for placing water collection trays.

[0008] Specifically, the connecting block is an integrally formed rectangular block in the shape of an I-beam, with splicing grooves on both its upper and lower surfaces, thereby forming a locking area in space for interlocking adjacent seedling box units. U-shaped grooves are also provided on its left and right sides for placing water collection trays.

[0009] Specifically, the seedling box unit is equipped with an integrated label slot.

[0010] Specifically, the seedling strips are made of biodegradable materials.

[0011] The beneficial effects of this utility model are as follows: 1. Efficient organization and no mixing: The support frame provides rigid partitions, and each seedling box unit holds a strip of hybrid seedlings, which completely avoids mixing between different varieties in terms of physical space.

[0012] Easy to operate and manage: The modular seedling tray design is suitable for large-scale centralized management. The label slot design makes information recording clear and intuitive. The entire seedbed is neat and uniform, greatly facilitating daily management tasks such as watering, fertilizing, observation, and data statistics.

[0013] Non-destructive transplanting with a high survival rate: During transplanting, simply lift the required strip of seedling from the seedling box unit, tear off the individual seedling pot with the seedling along the easy-tear connection, and directly plant it into the planting hole. The pre-set tear line at the bottom of the seedling pot ensures that the roots can grow smoothly. The pot itself degrades, truly achieving whole-root, non-destructive transplanting. There is no slow-growth period after planting, and the seedlings grow rapidly.

[0014] Eco-friendly and cost-effective: The seedling strips are made of biodegradable and environmentally friendly materials, requiring no recycling and saving time and effort. The support frame can be reused for many years, resulting in extremely low amortization costs, making it ideal for scientific research and large-scale production applications.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-7 As shown, a hybrid seed seedling raising device includes a support frame 1. At least two seedling box units 2 are arranged within the support frame 1. The seedling box units 2 are stacked along the length and height directions of the support frame 1 via connecting blocks 3. The connecting blocks 3 in the height direction are fixed to the support frame 1, and the connecting blocks 3 in the length direction are located at the transverse connection point of the two seedling box units 2 and fixed to the transverse guardrail 101 of the support frame 1, thereby completing the installation and fixation of one or more layers of seedling box units 2 on the support frame 1. Each seedling box unit 2 includes a rectangular frame 21 and a base plate 22 disposed within the rectangular frame 21. The base plate 22 has ventilation holes. The seedling box unit 2 is used to accommodate strip-shaped seedlings 4. The strip-shaped seedlings 4 are formed by multiple independent seedling pots 401 for holding seeds, linearly connected in series via easy-tear connecting parts 402.

[0018] Preferably, the seedling pot 401 has an inverted frustum-shaped opening structure that is larger at the top and smaller at the bottom, and a pre-set tear line 403 is provided at the bottom for the roots to pass through.

[0019] Preferably, the pre-set tear line 403 is either in the shape of a cross or in a ring.

[0020] Preferably, the lower half of the inner side of the left and right side plates of the seedling box unit 2 is symmetrically provided with guide grooves 23 along the length direction for placing the water collection tray 24.

[0021] like Figure 5 As shown, the connecting block 3 is an integrally formed rectangular block in the shape of an I-beam. Both its upper and lower surfaces are provided with splicing grooves 31, thereby forming a snap-fit ​​area 301 in space to snap the adjacent seedling box unit 2. U-shaped grooves 32 are also provided on its left and right sides for placing the water collection tray 24.

[0022] Preferably, the seedling box unit 2 is provided with an integrated label slot 5.

[0023] Preferably, the strip seedling strip 4 is made of biodegradable material.

[0024] Work process: 1. Build the framework: According to the breeding scale requirements, connect the connecting block 3 to the supporting frame 1 in a predetermined layout.

[0025] 2. Installation Unit: Insert the rectangular frame 21 of the seedling box unit 2 into the splicing groove 31 of the connecting block 3 through its edge. The connecting block 3 located in the length direction is fixed on the horizontal guardrail 101 of the support frame 1, thereby completing the installation and fixing of one or more seedling box units 2 on the support frame 1.

[0026] 3. Install water collection tray: Install water collection tray 24 on the guide groove 23 of the bottom seedling box unit 2. If the middle seedling box unit 2 needs to be equipped with water collection tray 24, it can be placed on the U-shaped groove 32 on the two adjacent connecting blocks.

[0027] Second stage: Sowing and planting in beds 1. Separate sowing: Seeds of different hybrid combinations are precisely sown into individual seedling pots 401 of different seedling strips 4. Each hybrid combination occupies a dedicated seedling strip 4, thus eliminating mixing at the physical source.

[0028] 2. Place the seedling strips 4 that have been sown flat into the corresponding seedling box unit 2, so that they are laid flat on the bottom plate 22.

[0029] 3. Labeling information: Insert the label with information such as the hybrid combination number and sowing date into the label slot 5 of the seedling box unit 2 to ensure that the information is clear and intuitive.

[0030] Phase 3: Seedling Management 1. Daily Management: Since all seedling box units 2 are neatly arranged within the support frame 1, daily observation, recording, fertilization, and pest and disease control are greatly facilitated. Because peony seeds have a relatively long germination period, after the seeds in the strip seedlings 4 have rooted and germinated, and the root system fills the entire seedling pot 401, even after puncturing the bottom of the entire seedling pot 401, the roots can still extend downwards to the ventilation holes within the seedling box unit 2. By pulling out the water collection tray 24, the overall condition of the root system can be clearly observed. The modular structure facilitates targeted management of specific combinations.

[0031] Phase 4: Transplanting seedlings 1. Precise seedling selection: When the seedlings reach the transplanting standard, accurately locate the seedling box unit 2 where the target hybrid combination is located based on the label information.

[0032] 2. Extracting the seedlings: Hold one end of the strip seedling 4 corresponding to the target hybridization combination directly with your hand and gently lift it upwards from the seedling box unit 2.

[0033] 3. Separating individual seedling pots: Easily tear off the required number of individual seedling pots 401 with intact soil clumps along the easy-tear connecting part 402 that connects each seedling pot 401 on the strip seedling strip 4.

[0034] 4. Non-destructive transplanting: Simply insert the torn individual seedling pot 401 directly into the pre-dug planting hole. There is no need to remove the seedling from the pot. The seedling pot 401 is made of biodegradable material that will naturally decompose in the soil; the pre-set tear line 403 at the bottom of the pot ensures that the root system is intact and undamaged, truly achieving transplanting with the entire root system intact and without slow seedling recovery.
