Description

Technical Field

[0001] The utility model belongs to the technical field of plant breeding, and in particular relates to a haploid seedling doubling immersion device. Background Art

[0002] Doubling of haploid seedlings refers to the process of doubling the number of chromosomes in haploid plants. It is a commonly used breeding method that can quickly obtain stable new varieties during the doubling process. During the breeding process, haploid seedlings need to be doubled by treatment with colchicine. The operation method is to immerse the roots of the haploid seedlings of the plant in a container filled with colchicine solution and soak them for a period of time. However, this method will have the following problems. When the haploid seedlings are soaked together, the haploid seedlings will tilt in the soaking bucket, resulting in non-standard soaking; moreover, the haploid seedlings will be piled up and squeezed, and then some haploid seedlings cannot ensure standard soaking, and the doubling effect is not ideal. Utility Model Content

[0003] The utility model aims to provide a haploid seedling doubling soaking device, and aims to solve the technical problems existing in the prior art.

[0005] Beneficial effects of this technical solution:

[0006] Place the haploid seedling between the positioning hole and the positioning tie, then pass the positioning tie around the haploid seedling and through the positioning hole, and fix the positioning tie with a fixing clip, so that the haploid seedling can be fixed on the display board. Fix the haploid seedling between the positioning hole and the positioning tie in turn, and after the haploid seedling is fixed, roll up the display board, and then place the rolled-up display board in the soaking bucket so that the root system of the haploid seedling is in contact with the liquid in the soaking bucket. After soaking for a suitable time, take out the display board.

[0007] The haploid seedlings can be fixed by the cooperation of the positioning holes, the positioning hoops and the positioning clamps, and a small number of haploid seedlings can be fixed in clusters, thereby ensuring that the positions of the roots of the haploid seedlings are consistent, ensuring uniform soaking, and avoiding problems such as different soaking effects and unsatisfactory doubling.

[0008] In another preferred embodiment of the present invention, the positioning tie comprises a binding portion fixed to the display board and a positioning portion away from the display board, and a plurality of positioning protrusions are arranged on the positioning portion along the length direction.

[0009] Beneficial effect: When the positioning clamp fixes the positioning hoop, it is located between the positioning protrusions. The positioning clamp can be restricted by the positioning protrusions to prevent it from sliding, thereby improving the fixing effect and preventing the fixed haploid seedlings from falling off.

[0010] In another preferred embodiment of the present invention, a plurality of connecting strips and supporting blocks are provided on the long sides of the display board, and the supporting blocks are fixed to one end of the connecting strip away from the display board.

[0011] Beneficial effect: The support block can support the root system of the haploid seedlings, preventing the haploid seedlings from falling between the positioning hoops during the fixation process.

[0012] In another preferred embodiment of the present invention, a plurality of soaking holes are provided on the support block.

[0013] Beneficial effects: The soaking holes can realize the flow of soaking liquid, which is convenient for soaking the root system of haploid seedlings.

[0014] In another preferred embodiment of the present invention, a clamping block is provided on another long side of the display board.

[0015] Beneficial effect: The clamping block can conveniently fix the display board in the soaking bucket to achieve position limiting.

[0016] In another preferred embodiment of the utility model, a plurality of clamping holes are arranged along the length direction on one side of the display board where the positioning clip is arranged, the clamping holes cooperate with the positioning protrusions, the clamping holes are blind holes, and the clamping holes and the positioning holes are located on the same horizontal plane.

[0017] Beneficial effect: after the haploid seedling is fixed by the positioning tie, the positioning protrusion on the free end can be inserted into the clamping hole to fix the free end of the positioning tie.

[0018] In another preferred embodiment of the utility model, a plurality of limit blocks are provided on one side of the display board where the positioning tie is provided. The limit blocks are arc-shaped, and the inner arc surface of the limit blocks faces the side away from the display board. The number of the limit blocks is consistent with the number of the positioning holes, and the limit blocks are all located between the positioning holes and the positioning tie.

[0019] Beneficial effects: The limiting blocks can wrap the haploid seedlings and improve the fixation effect.

[0020] In summary, the utility model reduces the accumulation of a large number of haploid seedlings by fixing the haploid seedlings in clusters. At the same time, the haploid seedlings are fixed by passing the positioning hoop through the positioning hole, so that the root system of the haploid seedlings is consistent and will not be displaced during immersion, thereby completing standard immersion and improving the doubling effect.

A plurality of positioning holes 3 are arranged in the middle of the display board 2 along the horizontal direction, and 10 positioning holes 3 are arranged in this embodiment.

[0031] The display board 2 includes a front side and a back side. A positioning tie 4 is provided on the front side of the display board 2 on the right side of the positioning hole 3. The number of the positioning tie 4 is the same as the number of the positioning holes 3. A limit block 5 is provided on the display board 2 between the positioning hole 3 and the positioning tie 4. The limit block 5 is arc-shaped, and the outer arc surface of the limit block 5 is fixed to the display board 2, and the inner arc surface of the limit block 5 faces the side away from the display board 2.

[0032] The positioning tie 4 includes a binding part and a positioning part, the binding part is fixed to the display board 2, and the positioning part is fixed to the binding part. A plurality of positioning protrusions 6 are sequentially arranged along the length direction on the positioning part, and the width of the positioning hole 3 is greater than the sum of the thickness of the positioning tie 4 and the width of the positioning protrusion 6, so that the positioning part can pass through the positioning hole 3.

[0033] Combination Figure 2 As shown, a plurality of clamping holes 7 are provided on the reverse side of the display board 2 on the left side of the positioning hole 3. The clamping holes 7 are blind holes, and the clamping holes 7 and the positioning hole 3 are both on the same horizontal plane. After the positioning tie 4 passes through the positioning hole 3, the positioning protrusion 6 on the positioning tie 4 is inserted into the clamping hole 7, so that the free end of the positioning tie 4 can be fixed. A positioning clamp 8 is provided on the reverse side of the display board 2 above the positioning hole 3. The positioning clamp 8 is vertically slidably connected to the display board 2. After the positioning tie 4 passes through the positioning hole 3, the positioning clamp 8 is slid downward, and the positioning clamp 8 is opened to clamp the positioning tie 4.

[0034] The bottom of the display board 2 is fixed with a connecting strip 9 below the limit block 5, and the bottom of the connecting strip 9 is fixed with a supporting block 10, which is perpendicular to the connecting strip 9 and is located on the side close to the front of the display board 2.

Then, the positioning protrusion 6 on the positioning tie 4 is inserted into the clamping hole 7 to fix the free end of the positioning tie 4, and at the same time, the fixing effect can be improved.

[0039] After the haploid seedlings are fixed, the support block 10 supports the bottom of the haploid seedlings, which can prevent the haploid seedlings from falling off under the action of gravity and also prevent the haploid seedlings from breaking.
