Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling equipment, specifically to a rice seedling tray liner for rice seedling cultivation. Background Technology

[0002] In rice cultivation, the seedling raising stage is crucial. Traditional rice seedling trays present numerous problems when raising mat-like seedlings. For example, mat-like seedlings suffer significant root damage during transplanting, leading to slow seedling recovery and impacting the rice's growth cycle and yield. Furthermore, seedlings raised in traditional mat-like trays are prone to root damage during transplanting due to their structural issues, prolonging the recovery period. Traditional pot-type seedlings, due to their raising and transplanting methods, are inconvenient for large-scale transportation, increasing production costs. Additionally, maintaining a suitable temperature within the seedling tray cannot be guaranteed. While some seedling raising aids exist, they still cannot effectively address the multiple needs of minimizing root damage, shortening the recovery period, ensuring convenient transportation, and maintaining a suitable temperature. Therefore, developing a novel liner for rice pot-type mat-like seedling raising trays is of significant practical importance. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A rice seedling tray liner for raising rice seedlings includes a seedling tray and a liner body that matches the seedling tray. The liner body is disposed inside the seedling tray. The liner body includes a grid plate with evenly arranged horizontal and vertical grids of seedlings. Multiple frustums are evenly distributed on the top of the grid plate. The grid plate has a circumferential side wall, and a retaining edge is provided at the upper end of the side wall. A positioning strip is provided on the retaining edge. A seedling guide strip is provided on the side wall of the grid plate, and the seedling guide strip is also located at the bottom of the retaining edge. A seedling guide strip groove matching the seedling guide strip is provided inside the seedling tray. The retaining edge of the liner body is also provided with an auxiliary detachment port, which is used to assist in the separation of the seedling tray and the liner body.

[0005] Furthermore, the grid of the bowl body is in the shape of a frustum.

[0006] Furthermore, the taper of the grid sidewall of the bowl body is 1:70.

[0007] Furthermore, each adjacent frustum is spaced 3 grids apart.

[0008] Furthermore, both the seedling tray and the bushing body are rectangular parallelepiped structures.

[0009] Furthermore, the retaining edge is provided with an outer extension edge along the width direction of the bushing body.

[0010] Furthermore, the grid disk, the frustum, the sidewall, the retaining edge, and the outer edge are integrated into one unit.

[0011] Furthermore, four auxiliary unloading ports are provided, which are evenly distributed on the short side of the bushing body's retaining edge and located at both ends of the outer extension edge.

[0012] Furthermore, the bushing body has two positioning strips on its long side and one positioning strip on its side; the positioning strip is a truncated pyramid that is narrower at the top and wider at the bottom.

[0013] Furthermore, three guide strips are provided on the long side of the sidewall, and two guide strips are provided on the short side of the sidewall; the guide strips are triangular prisms.

[0014] Beneficial effects:

[0015] The bushing of this invention effectively separates the mat-like seedlings into pot-like seedlings, greatly reducing root damage during transplanting, enabling the seedlings to recover quickly, shortening the rice growth cycle, and improving rice yield and quality. The unique structure and material design ensure good mat formation; during seedling cultivation, the mat-like seedlings develop better, facilitating centralized management and cultivation. Meanwhile, during transportation, the regular seedling structure and the protective function of the liner prevent the seedlings from being damaged or scattered, significantly improving the convenience of transportation and reducing transportation losses, providing strong support for large-scale rice seedling cultivation and planting. The liner body has guide strips around its sides, which ensures that the liner body can be more smoothly embedded into the seedling tray when the rice seedlings are raised in a mechanized manner using pot-shaped mat-like seedlings. The liner body has positioning strips above its guards, which can hold the bottom edge of the seedling tray when the rice seedlings are stacked in a mat-like mat-like pattern, ensuring the uprightness and stability of the stacked trays. The liner body has auxiliary tray removal openings on its guards, ensuring that the liner and seedlings can be separated smoothly when removing the seedlings. Attached Figure Description
