(a) Providing the nutritional medium according to one of claims 1 to 10 in liquid form;

(b) gelling the nutrient medium in the shape of a plant insert; and

(c) optionally sterilizing the nutrient medium.

15. Method for the automated or partially automated cultivation of plants, characterized in that the method comprises the following steps, wherein

(i) Contacting a plant insert according to one of claims 11 to 13 with a plant or plant part;

(ii) cultivating together a plant insert and a plant or plant part under growth conditions suitable for said plant, such that said plant or said plant part roots in said plant insert and the plant or plant part and plant insert constitute a plant unit; and

(iii) automatically combining the plant units

(iii.1) transfer into a cutout of a larger plant insert;

(iii.2) transfer to a cell in a culture plate; and/or

(iii.3) transfer into a soil substrate.

Drawings

Embodiments of the invention are schematically illustrated in the drawings. In the drawings:

fig. 1 shows different embodiments of a plant insert (12) according to the invention, which together with a tender shoot (10) constitutes a plant unit (8), wherein the plant insert (12) has the shape of a cylinder (a), a cuboid (B) or a hemisphere (C). In the embodiment shown in fig. 1(a), a plant slot (16) is introduced into a plant insert (12) into which a shoot (10) is inserted. The shoots (10) in FIGS. 1(B) and (C) are gently pressed into the surface of the plant insert (12).

Fig. 2 shows a plant unit (8) according to fig. 1, in which young shoots (10) have formed root systems (14) in corresponding plant inserts (12).

Fig. 3 shows the automatic transfer of the rooted plant unit (8) of the invention (see fig. 3(a)), wherein the plant unit (8) is inserted by means of a gripper (20) into a cutout in a larger, non-inventive plant insert, wherein the larger plant insert consists of a soil matrix (18) (see fig. 3 (B)). The gripper (20) comprises a gripper head (22) with two blades or tips, wherein by inserting the blades or tips into the plant insert (12) a good connection is created between the gripper (20) and the plant insert (12) so that the plant unit (8) can be transported by means of the plant insert.

Fig. 4 shows a plant insert (24) according to the invention consisting of 48 plant units (8) according to fig. 1 (B).

FIG. 5 shows an example of a plant insert of the present invention having rooted amelanchier without a shape stabilizing component;

FIG. 6 shows an example of a plant insert of the invention with rooted primula auriculata without a shape stabilizing component;

FIG. 7 shows an example of a plant insert according to the invention with rooted Echinacea having polyurethane foam BVB Sublime as the shape-stabilizing component;

FIG. 8 shows an example of a plant insert of the present invention having rooted edelweiss with polyurethane foam Oasis as a shape-stabilizing component; and

fig. 9 shows an example of a plant insert of the invention with rooted alum roots with polyurethane foam and coconut fibers as the shape stabilizing components.

Further advantages, characteristics and features of the present invention will become clear from the following detailed description of embodiments with the aid of the attached drawings. However, the present invention is not limited to these examples.
