The plastic material can be colored or translucent.

A method is already known in which the seeds are placed in pre-cultivated soil and a conical seed guard open at both ends is placed on the seeds so that the narrower end of the cone points upwards.

- · The purpose of the seed shelter is to protect the seed and the seed produced from it against adverse weather conditions and competition from other vegetation. The seedling germinating from the seed can then start its growth in complete isolation from the surrounding vegetation. At the same time, the seed guard retains heat and slows down the evaporation of moisture, so that the conditions for seed germination and seedling growth become favorable. The use of a seed shelter has proved to be particularly suitable in connection with forest sowing in nurseries.

The object of the present invention is to improve a previously known method. The invention is characterized in that the seeding cone is pushed into the untreated soil at the tip end. This achieves some significant advantages. Expensive and cumbersome mechanical pre-processing of the country is eliminated. The tip of the cone crushes the topsoil and the seed meets the humus-rich soil layer necessary for germination. The seed germination phase takes place below the surface vegetation in a humid and protected environment. The cone prevents the surface vegetation from falling over the locust seedling in the fall and suppressing the seedling.

The invention also relates to a sowing cone for carrying out the method. The seeding cone is characterized in that it has a base at the tip end with holes or which is easily broken. When such a sowing cone is pushed into the ground, soil, which acts as a seed growing medium, penetrates through it through the holes. The base may also be intact, but so weak that it breaks when the cone is pushed into the ground. This ensures that the seeds can be placed in advance in the seed cones and stacked in a package that is easy to transport.

When the sowing cones are then pushed into the ground one at a time, the ground is broken at this point, and at the same time the bottom of the sowing cone is broken and the seeds thus enter the soil.

A preferred embodiment of the seeding cone is characterized in that it has slots in the bottom to facilitate breakage. The slots can be located on the circumference of the base so that the base comes off completely when the seed cone is pushed into the ground.

The slits in the bottom of the seed cone can also extend radially from the circumference of the bottom to the center. When such a sowing cone is pushed into the ground, the sector-like parts of the base bend upwards and anchor the sowing cone firmly to the ground.

On the other hand, in the case of such seed cones, a special tool can be used to push them into the ground. The tool is preferably formed by an arm with a handle, the lower end of which has, for example, a conical pusher whose diameter is smaller than the diameter of the bottom of the sowing cone.

The invention will now be described with reference to the accompanying drawing, in which

Fig. 1 shows a sowing cone according to an embodiment of the invention inserted into the ground and cut.

Fig. 2 shows sowing cones according to another embodiment of the invention stacked and cut into packages.

Fig. 3 shows a section taken along the line III-III in Fig. 2.

Fig. 4 corresponds to Fig. 3 and shows another embodiment of the invention.

Fig. 5 shows the sowing cone according to Fig. 4 inserted and cut into the ground.

Fig. 6 shows a tool used in connection with the seeding cone for pushing the seeding cone into the ground.

Fig. 1 shows a situation in which the sowing cone 1 is inserted into the ground 2 ~~ tip above. The sowing cone 1 has crushed the ground inside the cone, into which a few seeds 3, for example tree seeds, have been dropped. Because the soil surface is crushed, germination occurs under favorable conditions. The seeding cone 1 is preferably a naturally degradable plastic, although this is not necessary.

Figure 2 shows a part of a package in which the sowing cones 1 are nested. Such a package requires little space and is easy to transport. The sowing cones 1 are provided with bases 4 and seeds 3 have been dropped in advance inside each sowing cone 1. The bases 4 can be, for example, as shown in Fig. 3. The circumference of the base 1 has two semicircular slits 5 and the base is held in place by only two narrow bases 6. When such a sowing cone is pushed the tip above the ground, the base 4 comes off and the seeds 3 roll onto the surface of the broken soil.

On the other hand, the bottom of the seeding cone 1 may be as shown in Fig. 4_. Here, there are slits 7 extending radially from the circumference of the base to the center so as to form sector-shaped tabs 8.

^ When such a sowing cone is pushed into the ground, the tongues 8 bend upwards and the gaps between them open, whereby the seeds fall to the surface of the broken ground. When pushed deep enough, the tongues 8 firmly anchor the seeding cone 1.

On the other hand, seed drills with bottoms shown in Figs. The tios can be pushed into the ground by means of the tool shown in Fig. 6, which is formed by an arm 10 with a handle 9, the lower end of which has a conical pusher 11 with a tip diameter smaller than the diameter of the bottom 4 of the seed cone 1. Fig. 5 shows a situation in which the sowing cone 1 provided with the base according to Fig. 4 has been pushed into the ground with the tool according to Fig. 6.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the claims set forth below. Thus, the conicity of the seed cone may differ from the examples shown in the drawing. It is essential that the narrower end of the seed cone to be inserted into the ground is so small that it breaks the ground surface inside. If the seed cone has a bottom with slots, the pattern formed by the slots may be different from that shown in the drawing.
