A container tray for growing plants is known, containing a plurality of interconnected containers, each container has a tubular shape tapering downwards, the upper edge of which forms an opening in the container, and a bottom containing a grid having a central opening into the inner part of the container, a plurality of vertically oriented ribs formed on the inside of the tubular mold, and a plurality of vertically oriented slots formed in the tubular mold, each having a lower end adjacent to the bottom of the container. Said plurality of containers are interconnected along their upper edges. The tray has a surface inclined inwardly and toward the bottom of each container from the lower end of each slot. The tray contains a protrusion from each rib, and each protrusion is inclined from the rib associated with it to the slot (patent No. AU 651546, IPC A01G9/10, publ. 21.07.1994).

Known cassette for growing seedlings, which is a container made of shock-resistant frost-resistant plastic, in the form of a rectangular cassette containing a platform with cells of a square shape with beveled corners in the plan in the upper and lower planes, tapering downwards, and made a hole in the lower plane of each cell, the walls of which are interconnected by stiffeners and have vertical slots to a height of two thirds of the height of the cell wall, in the ribs separating the cells in the upper part, slotted slots are made 10 mm high from the upper edge and 2 mm wide (patent No. 2553645, IPC A01G 9 /00, published 06/20/2015).

Known tray for seedlings with an improved structure, including the body of the tray for seedlings with a given area. The body of the seedling tray is provided with several recessed holes at intervals of the required number of seedlings, and the hole grid provides an environment for filling, storage and seedlings. The cavity is hollowed out in the upper and lower axial directions and has a central axis, and a plurality of medium resistance surfaces located in the longitudinal direction around the central axis, and the upper end of the medium resistance surface is separated from the distance of the central axis is greater than the distance between the lower end surface of the medium resistance surface and the central axis. Any two opposite medium resistance surfaces form a flow restriction angle limiting the fixation of the medium, and the end surface of the medium resistance surface is concave. A root blocking slot is provided with a fixed slot width and longitudinal expansion, whereby the fixed slot width and air pass through the central axis in the axial direction through the cavity, block the radial development of the roots of planted seedlings and stimulate the formation of branched roots (patent No. CN 211297805 U, IPC A01G 9/02908, published 21.2020).

The closest in terms of essential features is a seedling cassette containing a plurality of containers interconnected along their upper edges, having a tubular shape tapering downwards, in cross section representing a symmetrical octagon, consisting of four wide walls and four narrow walls, the upper edge of which forms a hole in the container, and a bottom containing a grid having a central opening, a plurality of vertically oriented ribs formed on the inside of the tubular shape, and a plurality of vertically oriented slots formed in the tubular shape, the wide wall of the container is flat and concave, protruding inward and made obtuse, part, while the top of the concave part is located at some distance from the upper edge of the container, and the lower edge of the wide wall has a broken shape, the ribs are located on the inwardly protruding concave part of the wide wall and on the narrow wall, and the vertical slots are located on the flat part of the wide wall. The container with the cage is connected to each other by means of vertical jumpers (patent No. RU 211763, IPC A01G 9/00, A01G 9/02, A01G 9/029, publ. 06/22/2022).

The above technical solutions have qualities that make it possible to grow seedlings with a closed root system.

The technical problem to be solved by the proposed technical solution is to improve the design, which allows to stimulate growth and evenly distribute the root system during growth.

The technical result coincides with the task and is achieved due to the fact that in a forest seedling cassette containing cells interconnected along their upper edges, each cell has a tubular shape tapering downwards, in cross section representing an octagon with side and corner walls, vertical slots , made on the walls of each cell, the bottom of each cell is made with a hole, the cells are connected to each other and to the cage by means of vertical jumpers, the side walls are made with a vertical angular cavity, the top of which is directed inside each cell, and with vertical grooves made on the straight sections of the side walls and corner walls, while in the connected state of the upper edges of neighboring cells along the perimeter, through holes are formed, and the bottom of each cell is made with a ring that unites these vertices.

The vertical cavity is made V-shaped and runs along the entire height of the side wall, the vertical slots are made intermittent, located in vertical grooves, occupy about ¾ of the cell height in its lower part, in the connected state of the upper ribs of adjacent containers, through diamond-shaped holes are formed along the perimeter. Each cell is made with a reinforced belt located along the entire outer perimeter in its upper part, while the wall thickness of this belt exceeds the thickness of the underlying part of the wall of each cell with the formation of a step.

New features of the proposed technical solution is the implementation of the side of each cell with a vertical corner cavity, the top of which is directed inside each cell, and with vertical grooves made on the straight sections of the side walls and on the corner walls, while in the connected state of the upper ribs of adjacent cells along the perimeter through holes are formed, and the bottom of each cell is made with a ring that unites the indicated vertices. The execution of angular depressions on the sides of each cell and the presence of vertical grooves makes it possible to form a longitudinally extending angular groove in the soil for guiding the roots, as well as the execution of vertically oriented intermittent cuts on the walls of each cell increases the air flow for the development of seedling roots, prevents them from twisting and promotes the formation of active root tips ready for growth when planting seedlings. And the through holes obtained along the perimeter of the cells and the execution of the bottom of each cell with a ring that unites the indicated vertices makes it possible to regulate the water balance when watering the plants.

Thus, an improved design of the forest seedling cassette was obtained, which makes it possible to stimulate growth and evenly distribute the root system during growth. The technical result has been achieved.

The utility model is illustrated by drawings:

fig. 1 - forest seedling cassette, general view from a ¾ perspective;

fig. 2 - forest seedling cassette, side view;

fig. 3 - view A in Fig. 2.

fig. 4 - forest seedling cassette, top view;

fig. 5 - view B in Fig. 4.

The forest seedling cassette is made of high-strength composite material. Working with solid cassettes can be easily mechanized and automated. For example, the supply of cassettes to the filling and sowing line, the pushing of seedlings from the cells and their packaging can be done mechanized.

The seedling cassette contains cells 1 connected to each other along their upper edges. Cells 1 are united by a holder 2, which slightly extends outward from cells 1, this allows stacking the cassettes. At the corners, the holder 2 is provided with grooves 3, which facilitate the release of adjacent stacked cassettes from the stack.

Each cell 1 has a tubular shape tapering downwards, in cross section representing an octagon with side and corner walls 4 and 5, respectively.

The side walls 4 are made with a vertical V-shaped corner cavity, passing along the entire height of the wall 4, the top 6 of which is directed into the cell 1. On the straight sections of the side walls 4 and at the intersection of the corner and side walls 4 and 5, respectively, vertical grooves 7 are made. the location of the grooves 7 at the intersection of the corner and side walls 4 and 5 occurs in a checkerboard pattern, i.e. through one corner (Fig. 3). In the connected state of the upper edges of neighboring cells 1, through diamond-shaped holes 8 are formed along the perimeter.

On the walls 4 and 5 of the cells 1, vertically oriented slots 9 are made, which are discontinuous, which occupy about ¾ of the height of the cell and are located in the vertical slots 7 in their lower part. Slots 9 prevent the formation of a lack of oxygen in the peat clod in cells 1 and at the same time act as a drain in case of excessive watering.

The bottom of the cells 1 is made with a hole with a ring 10, which unites the indicated tops 6 and makes the cell structure more rigid. In addition, the ring 10 helps to keep the soil inside the cell 1. Excess irrigation water easily flows out of the bottom hole. Thanks to the open bottom of the cells 1, watering is also possible from below. In this case, the cassette is provided with a tray.

Each cell 1 is made with a reinforced belt 11 located along the entire outer perimeter in its upper part, while the wall thickness of the belt 11 exceeds the thickness of the underlying part of the wall of each cell 1 with the formation of a step.

Cells 1 and cage 2 are connected to each other by means of vertical jumpers 12. Vertical jumpers 12 are evenly distributed along the perimeter of cells 1.

The inner surface of the cells 1 has a glossy surface, which greatly facilitates the removal of seedlings from the container 1.

The dimensions of each cell 1 (height and length of the walls) can vary over a wide range, which determines the number of cells in the cassette.

The inventive forest seedling cassette can be made on standard equipment from modern materials using modern technologies.
