Description

The invention relates to a planting device for improving the growth of young plants, in particular trees, comprising a hollow protective device for protection against adverse weather and damage caused by game such as browsing and sweeping damage. The invention also relates to a method for planting with planting devices.

Such a planting device is already off EP 0 558 356 B1 known. Its tubular protective device made of plastic is used for this purpose, as is the case with FR 2 621 441 A1 and DE 78 32 685 U , arranged around the young plant. As a result, the young plants, which are particularly threatened by browsing, are much better protected from game and also grow faster due to the improved microclimate. As a result, the forestry yield is noticeably increased because a larger number of trees survive the young plant age and practically all plants in the young plant age grow faster.

However, this yield is only possible if a corresponding effort is made. In a first step, the young plant is grown, for example in a greenhouse or in a tree nursery, and later released in a second step at the destination, in order to then set up the tubular plastic protective device at the destination in a third step. As soon as the young plant protrudes from the protective device, the protective device is removed in a fourth step, as long as this is still possible in a non-destructive manner.

This four-step procedure is complex and accordingly expensive. The invention is therefore based on the object of decisively reducing the effort involved in afforestation or planting, without this resulting in noticeable drops in yield.

This object is achieved by a planting device for improving the growth of young plants, in particular trees, comprising a hollow protective device for protection against adverse weather and damage from game, the protective device having at least one wall,
wherein the planting device comprises a seed capsule, the seed capsule having a water-absorbent substrate, one or more seeds, preferably tree seeds, being at least partially enclosed by the substrate, the seed capsule being received in the protective device or being received by the protective device.

The invention is initially based on the knowledge that the first, conventional step of growing young plants in a greenhouse or growing them outdoors in a tree nursery and then placing them or moving them to a destination involves considerable effort. The invention is also based on the knowledge that the water-absorbent seed capsule increases the likelihood of germination so much and the protective device protects the seedling so well that this results in a possible slight decrease in yield compared to cultivation in a greenhouse due to the lower planting effort is overcompensated. For this reason, the invention pursues a new, radical approach, according to which the growing of young plants in a greenhouse should be dispensed with in the future.

According to the invention, it is therefore provided that direct sowing is carried out at the target location. For this purpose, the protective device and the seed capsule are placed at the target location. This minimal effort per plant accelerates the planting process drastically, which frees up otherwise urgently needed capacities in forestry. This is, for example, tree care, which offers considerable opportunities for increasing yields. As has been found, this is often above the advantages of the conventional method (growing young plants far away from the target location) compared to direct sowing using a protective device and seed capsule. As a result, the above-mentioned object is achieved by the planting device according to the invention by means of overcompensation.

Finally, it was found that there is a potential for error when planting or moving early young plants, since the roots usually only develop in the same direction of growth. If the roots are incorrectly aligned or even bent when planting, the roots will continue to grow in this direction. As a result, the developing tree has too little ground support and loses its static stability, which sooner or later results in a total loss of the tree. It can also easily happen that the plant or tree does not even take root after it has been planted or moved. The direct sowing according to the invention thus also contributes to the solution of the aforementioned problem in this way.

It is very preferred that the protective device comprises a plastic. The plastic is preferably translucent. The term “translucent” means in particular transparent or translucent materials. The term “transparent” means clear materials such as Meant Plexiglas or window glass. In contrast, the term “translucent” preferably means materials that scatter light and thus appear milky or that make the contours behind this material appear blurred. It is very preferred that the term “transparent” means that the contour of a plant within the protective device is sharp when viewed from the outside. The expression “translucent” particularly preferably means that the contour of a plant inside the protective device can be seen from the outside, but is not sharp, but is perceived as blurred or milky blurred.

The protective device is preferably a tube and more preferably a cylindrical tube. It is expedient that the tube is closed circumferentially over a large part of its length. It is possible that the tube has a continuous longitudinal slot and is, for example, continuously C-shaped. It is particularly preferred that the pipe is manufactured by means of extrusion. It is possible that the tube is designed as a polygonal tube and in particular as a triangular tube or square tube. It is within the scope of the invention that the tube or the protective device is formed into a polygonal tube by folding a flat element and, for example, is closed or fixed to a polygonal tube via tabs with corresponding complementary openings. According to one embodiment, the protective device can be an injection-molded part or comprise a plurality of injection-molded parts. It is possible for the protective device to be a combination of at least one extruded part and at least one injection-molded part. According to one embodiment, the protective device or a bud protection part is produced by means of an additive method (three-dimensional printing). This is particularly advantageous in the case of complex structures, for example partially open network structures or translucent and opaque areas on a part (in particular on the protective device). So z. B. hollow chambers are filled with active ingredients while printing.

It is possible for the protective device to be designed in the shape of a truncated cone or a truncated pyramid. The protective device preferably has a length of at least 10/15/20 cm. It is preferred that the length of the protective device is at most 200/160/140 cm in length. The wall thickness of the protective device is expediently at least 0.5 / 0.75 / 1.0 mm. The wall thickness of the protective device is advantageously at most 3/2 / 1.5 mm. It is preferred that an inside diameter or an edge length of the protective device in an uppermost region is at least 15/18/20 mm. It is preferred that an inner diameter or an edge length of the protective device in the uppermost area is at most 150/120/100 mm.

It is particularly preferred that the protective device is at least partially and preferably completely biodegradable. It is preferred that the protective device consists at least partially and preferably completely of renewable raw materials. The term “biodegradable” should preferably be understood in the sense of EN 13432 and / or EN 141959. It is very preferred that the protective device comprises a biodegradable plastic. It is advantageous if the protective device comprises a plastic which consists at least partially and preferably completely of renewable raw materials. Biodegradable plastics are, for example, polylactides (PLA), polyhydroxyalkanoates (PHA), thermoplastic starch (TPS), polycaprolactone (PCL), polybutylene adipate terephthalate (BPAT) or polybutylene succinate (PBS). Examples of plastics made from renewable raw materials are cellulose acetate (CA), bio-polyethylene (bio-PE), polyethylene furanoate (PEF), PLA, PHA, or TPS.

It is very advantageous that the plastic of the protective device is at the same time biodegradable and consists of renewable raw materials, including in particular the plastics PLA, PHA and TPS. Since polylactides are often only industrially compostable and since thermoplastic starch has a strong tendency to absorb water, polyhydroxyalkanoates appear to be an ideal group of plastics for the present purpose. These can be designed to be transparent or translucent, are not soluble in water and yet can be composted on the forest floor. The mechanical properties of PHA are similar to those of polypropylene (PP). The mechanical properties can also be controlled using a large number of biodegradable additives.

According to a particularly preferred embodiment, the protective device or the wall of the protective device or the plastic of the protective device comprises a functional substance, preferably a fertilizer and / or activated carbon and / or a dye, for acting on the young plant. It is particularly preferred that the wall of the protective device comprises a biodegradable plastic and at least one functional substance, in particular a fertilizer and / or an agent for pest control. The dye may serve as a light filter to adapt the light spectrum to the needs of the young plant. It is very preferred that the protective device or the wall of the protective device is designed in such a way that the biodegradable plastic releases the at least one functional substance as part of the biological decomposition of the plastic. In this way the young plant will benefit even after months or years, even if the protective device is no longer in place. In particular, work steps for subsequent fertilization are then omitted, so that the basic idea of the invention is even more pronounced.

It is possible for at least one wall section of the wall of the protective device to have a hollow chamber material. It is advantageous if activated carbon is arranged in the hollow chamber material or in the hollow chambers. It is preferred that, in a plan view, the wall section is assigned to an angular section and, for example, corresponds to an angular section of 30 to 180 °. It is particularly preferred that the wall section with activated carbon is aligned to the north, so that the young plant receives more heat radiation from the north. It is within the scope of the invention that the protective device is more slowly biodegradable in a lower area, in particular in an area in the ground, than in an upper area. For this purpose, the lower area can, for example, have a multi-layer design. According to one embodiment, the protective device comprises a mesh material or a sieve-like material which extends over at least one section in the radial and / or axial direction. It is possible that the protective device is a stabilizing element, e.g. B. in the form of a rod or a wall thickening includes.

The substrate preferably comprises activated carbon and particularly preferably biochar (“biochar”). The term “biodegradable” is preferably meant in the sense of EN 13432 and / or EN 14995. The word “porous” preferably means a material which has micro and / or meso and / or macro pores. The term “porous” means in particular those materials whose pores are distributed over the entire material and do not only occur locally, such as air inclusions. For the purposes of this invention, micropores have an average diameter of less than 2 nm, mesopores an average diameter of 2 to 50 nm and macropores an average diameter of more than 50 nm. The porosity of the substrate of the seed capsule is preferably at least 0.3 / 0, 4 / 0.5. The porosity of the substrate is advantageously at most 0.9 / 0.8 / 0.75. The term "porosity" refers to the bulk density of the substrate material, where the porosity = 1 - bulk density / true density. The term “bulk density” is also called “apparent density” or “volume weight”. For this purpose, a certain volume of the substrate material is preferably removed and then weighed. The term “true density” preferably means the density of the substrate material without any inclusion of air, which is preferably to be determined using data sheets or lexical works and is also called “absolute density” or “true density”.

It is very preferred that the substrate of the seed capsule has at least one active ingredient, in particular a fertilizer and / or a reaction inhibitor and / or a substance for pest control and / or a substance for promoting beneficial insects and / or a substance for mineral enrichment or pH value regulation (in particular magnesium and / or calcium or lime, including powdered limestone or quicklime) at the destination or in the ground. The at least one active ingredient is preferably adapted to the intended use or to the seeds. It is advantageous if the substrate has a binding agent so that, for example, the activated carbon is better kept in shape. It is expedient that the material of the substrate, in particular the activated carbon and / or the at least one active ingredient and / or the binding agent, is pressed and is, for example, cube-shaped, cuboid, spherical or egg-shaped. It is possible for the substrate to have a release agent near the surface, for example a paraffin oil or a carnauba wax. The release agent is preferably used for better separation of the pressed substrate material from a molding tool.

It is preferred that the seed capsule has a biodegradable and / or water-absorbent outer layer which at least partially encloses the substrate. The outer layer comprises, for example, cellulose and / or lignin and / or hydrogel and is preferably used to form a smooth or clean closure of the seed capsule. The outer layer of the capsule can be produced using the additive process or the fiber casting process. It is possible to apply the outer layer or another layer of the seed capsule to the z. B. to apply substrate produced by pressing by means of additive or fiber casting processes. In the case of additive processes, it is also possible to produce the outer layer in parallel while filling the seed capsule with seeds and substrate.

According to a very preferred embodiment, the planting device comprises a bud protection part. It is advantageous that the bud protection part can be placed or placed loosely on the protective device so that a young plant can lift the bud protection part from the protective device as it grows. It is useful if the bud protection part protrudes or can protrude into the protective device. The bud protection part preferably comprises a support element, for example a support projection, so that the bud protection part does not or cannot slide into the protective device. The bud protection part advantageously closes off an upper end of the protective device. It is advantageous if the bud protection part has one or more air holes. It is very preferred that the bud protection part consists of or comprises a, preferably biodegradable, plastic. It is useful that the bud protection part consists of the same material as the protective device. The bud protection part is preferably translucent and in particular transparent or translucent. The bud protection part is expediently an injection-molded part made of plastic. According to a very preferred embodiment, the bud protection part tapers towards the top to a point. It is preferred that the bud protection part has a taper in a lower area for receiving a pioneer bud and for support on the trunk of the young plant. In a lowermost area, the bud protection part advantageously comprises a downwardly pointing widening for guiding the pioneer bud, preferably in the direction of the taper.

It is advantageous that the protective device and / or the bud protection part has or have a marking element. The marking element can be, for example, a flag or a color marking, by means of which, for example, the type of tree can be recognized.

It is possible for the protective device to have a holding element and / or a holding part for holding the seed capsule in the protective device. The holding element is preferably arranged at one end, preferably at the lower end of the protective device, in such a way that the seed capsule cannot fall out of the protective device at this end or at the lower end. It is advantageous if the holding part is arranged at one end, preferably an upper end, of the protective device in such a way that the seed capsule cannot fall out of the protective device at this end or an upper end. It is particularly preferred that the holding element or the holding part reduce an effective, inner cross-sectional area of the protective device. The expression “effective cross-sectional area” preferably means that the seed capsule cannot pass through the area of the holding element or the holding part due to the holding element or the holding part. It is advantageous if the holding element is arranged at the lower end of the protective device in such a way that the seed capsule - after the protective device has been introduced into the ground - automatically has contact with the ground. The holding element is preferably located within the lowest half / the lowest third / quarter / fifth / sixth of the protective device. It is advantageous if the holding part is located in an upper half / in an upper third / quarter / fifth / sixth of the protective device. It is particularly preferred that the holding element and / or the holding part is connected in one piece and preferably integrally to the wall of the protective device. According to a preferred embodiment, the holding element and / or the holding part is separated from the wall of the protective device in sections by cutting or punching. The cut or the punching can be designed, for example, U-shaped or V-shaped or II-shaped. The cut / punched holding element and / or holding part is preferably produced by a plastically deforming inward bending. According to one embodiment, the holding element or the holding part is produced, for example, by squeezing or thermoforming, so that the effective, inner cross-sectional area at the respective point of the protective device is reduced. It is possible that the holding element and / or the holding part is a plug. The holding part is advantageously arranged above the holding element in an erected state of the protective device. It is particularly preferred that the seed capsule is arranged between the holding part and the holding element, so that the seed capsule is preferably arranged in the protective device so that it cannot be lost.

It is preferred that the protective device has a lower, downwardly tapering wall end and / or an upper, rounded wall end. The term “rounded” also means in particular angled ends, which are created, for example, by kinking or folding. It is preferred that only the outside of the lower wall end tapers downwards, which can be produced, for example, by turning. It is particularly preferred that the upper wall end is thickened, which can be produced, for example, by thermoforming. A thickening of the upper wall end is particularly advantageous if the protective device is to be driven into the ground by means of a hammer and pickguard due to a hard surface.

To achieve the object mentioned at the beginning, the invention teaches a seed capsule, in particular with at least one of the aforementioned features, comprising a water-absorbent substrate and at least one seed, in particular a tree seed, the substrate at least partially and preferably completely enclosing the seed. In some operations it is advantageous to do without the protective device and only to place the seed capsule at the target location. It is possible, for example, to distribute the seed capsules by means of aircraft (manned or unmanned, copters and / or aircraft, in particular multicopter drones), so that the effort is once again drastically reduced. If, after some time, it should be determined that a larger number of seed pods has not risen at the target locations, a second drone flight can deploy further seed pods at these target locations, so that the number of young plants is increased considerably.

The above-mentioned object is achieved by a method for planting, in particular with planting devices with at least one of the aforementioned features, wherein a planting device has a hollow protective device and a seed capsule, the protective device comprising at least one wall, the seed capsule having a water-absorbent substrate and at least having a seed, in particular a tree seed, the substrate at least partially enclosing the seed, the protective device being fixed at a target location in the soil, the seed capsule being arranged in the protective device.

The term “target location” preferably means the final setting location and thus preferably the location of the later tree felling. It is possible for the seed capsule to be arranged on the ground first, and only then to insert the protective device around the seed capsule into the ground. It is also possible to first set up the protective device and only then to throw the seed capsule into the protective device and, if necessary, to press it against the ground with a pressure stick. It is within the scope of the invention that the protective device contains the seed capsule immediately before the protective device is set up, the seed capsule preferably being held in the protective device by a holding element or a holding part. This variant is particularly interesting for the automated or partially automated sowing with the help of sowing machines or planting machines. It is preferred that the holding element is designed in such a way that when the protective device is set up, the holding element automatically enables the seed capsule to come into contact with the soil. It is advantageous if a bud protection part is designed in such a way that the holding part is automatically pressed against the wall of the protection device when the bud protection part is placed on the protective device, because this prevents injuries to the young plant.

• 2 die erfindungsgemäße Pflanzvorrichtung aus 1 in einem Längsschnitt, nachdem sie im Erdreich fixiert und ein Knospenschutzteil aufgesetzt wurde und
• 3 eine Seitenansicht der Pflanzvorrichtung aus 1 ohne Saatkapsel.

The invention is explained in more detail below with reference to figures of an exemplary embodiment. Show it:

• 1 a longitudinal section through a planting device according to the invention immediately before contact with the ground,
• 2 the planting device according to the invention 1 in a longitudinal section after it has been fixed in the ground and a bud protector has been put on and
• 3 a side view of the planting device 1 without seed capsule.

In 1 is a planting device according to the invention with a protective device 1 in the form of a tube and a seed capsule 3 pictured. The protective device 1 is designed essentially as a hollow cylinder and has a correspondingly shaped wall for this purpose 2 on. The protective device 1 preferably comprises a thermoplastic plastic as the most important component, in particular a polyhydroxyalkanoate such as polyhydroxybutyric acid and is preferably produced by means of extrusion. The material of the wall 2 may also contain a fertilizer, for example nitrogen, potassium and / or phosphorus. In this embodiment, the wall is 2 not transparent, but rather translucent or milky light gray due to the fertilizer. Nevertheless, the young plants are provided with a completely sufficient amount of light. The plastic in this exemplary embodiment comes from renewable raw materials.

The protective device 1 has a lower wall end 10 and an upper wall end 11 on. In this embodiment, the lower end of the wall tapers 10 on its outside downwards so that the wall 2 the protective device 1 in longitudinal section 1 tapering to a point and therefore better in the ground 12th drifting. This taper can be produced, for example, by means of turning and, if necessary, also by means of thermoforming. The top of the wall 11 on the other hand, in this exemplary embodiment it is rounded and has an approximately teardrop-shaped thickened contour in longitudinal section. This thickening at the upper end of the wall 11 is achieved, for example, by thermoforming, so that the top wall end 11 significantly more stable than the lower end of the wall 10 is. This increased stability is particularly advantageous when the fixation of the protective device 1 in the ground 12th difficult and then preferably using a hammer and pickguard.

In this exemplary embodiment, the protective device comprises 1 furthermore a holding element 8th at its lower end and a holding part 9 at their upper end. Both the retaining element 8th as well as the holding part 9 are both web-like and protrude into the interior of the protective device 1 into it. In 3 it can be seen that the retaining element 8th and the holding part 9 by punching the wall in a U-shape 2 with subsequent pressing in of the retaining element 8th or the holding part 9 have arisen. So that both the retaining element 8th as well as the holding part 9 integral parts of the wall 2 the protective device 1 . There are also window-like openings through the punchings 13th , 14th in the wall 2 developed. Function of the holding element 8th and the holding part 9 is it, a seed pod 3 in the protective device 1 to keep. This eliminates the step of placing the seed capsule 3 in the protective device 1 at the destination.

While in 1 the moment shortly before penetration into the ground 12th is shown in 2 those already in the ground 12th fixed protective device 1 pictured. Here is the soil 12th a little way into the protective device 1 penetrated so that the retaining element 8th automatically on the wall 2 or also in the wall 2 and in the corresponding window 13th was pressed. This causes the seed capsule to lie 3 now directly on the ground 12th on.

The seed capsule 3 has an outer layer 6th which in this embodiment comprises cellulose and is therefore water-absorbent. The outer layer 6th encloses a substrate 4th completely, which in this embodiment mainly consists of activated carbon in the form of biochar. The substrate 4th in turn encloses a seed 5 which in particular can be a tree seed. It is beneficial if the substrate 4th contains a fertilizer that is specially made for the seeds 5 is matched. In addition, the substrate can 4th have a reaction inhibitor which prevents the fertilizer from acting too early. Finally, it can be advantageous if the substrate comprises a plant protection agent which is beneficial to the seeds 5 is matched.

In an outer area of the substrate 4th there is preferably a release agent, which can be, for example, a paraffin oil. The release agent enables a clean shaping when pressing the activated carbon, so that a uniformly shaped product is created. Due to the tendency to form crumbs, the substrate is 4th made of activated carbon with the outer layer 6th made of cellulose, so that the seed capsule gives off a clean, smooth and rounded and therefore high-quality appearance. In addition, the coating is with the outer layer 6th an advantage during production and subsequent logistics.

The effort involved in making the outer layer 6th is accepted because activated carbon or biochar (also called biochar) offers outstanding advantages in terms of water absorption. This water absorption capacity is ensured by the micro, meso and macro pores of the activated carbon, so that the water comes out of the ground 12th and from the air quickly into the seed capsule 3 penetrates and the seed 5 is moistened just as quickly. This creates the seed 5 to the seedling and soon bursts the seed capsule 3 on. While the seedling grows into a young plant, the active ingredients or the fertilizer in the seed capsule go 3 into the ground 12th over and can thus be absorbed by the roots of the young plant. In this way, particularly rapid growth of the plant or tree is achieved at a very young age.

This already rapid growth is accelerated by the fact that in the protective device 1 a microclimate prevails which is similar to that of greenhouses. For this purpose, a bud protection part is provided in this exemplary embodiment 7th according to 2 at the top of the protective device 1 put on. The bud protection part 7th assigns a section 18th , 20th which is inside the protective device 1 is arranged so that the bud protection part 7th especially not from strong winds from the protective device 1 can be torn out. The section 18th , 20th is dimensioned so that it sits loosely in the protective device and the holding part 9 automatically into the opening 14th moved back. So the bud protection part is 7th only very loose in the protective device 1 fixed and is supported by a support projection 17th falling into the protective device 1 prevented.

The bud protection part 7th runs upwards in this embodiment and simulates in the middle of the longitudinal section 2 a peak 19th . This taper of the bud protection part 7th serves to keep the pioneer bud of the young plant in the area of the tip 19th is absorbed so that the young plant will protect the bud as it continues to grow 7th gradually out of the protective device 1 highlights. This protects the pioneer bud, which is so important for the growth of the young plant, from being bitten in the further course. The section 18th , 20th in the protective device 1 preferably has a taper 18th and underneath a widening 20th on. The expansion 20th serves to guide the pioneer bud during growth so that it can find its way through the rejuvenation 18th finds. The rejuvenation 18th leads to the bud protection part 7th sits closer to the trunk and does not fall off so easily if the young plant continues to grow.

The bud protection part 7th also has upper air holes in this embodiment 16 on which in connection with lower air holes 15th the protective device 1 enable air exchange in the manner of a chimney. This ensures that fresh air and, above all, carbon dioxide constantly reach the young plants, so that they have the substance that is so important for growth available in sufficient quantities.

As soon as the young plant is large enough and out of the protective device 1 emerges, at least the pioneer bud is still through the bud protection part 7th protected. The rounded top end of the wall 11 ensures that the young plant is not injured on sharp edges in the event of movements caused by wind, for example. Due to the biodegradability, the forest manager does not even have to dispose of the protective device 1 or the bud protection part 7th make, because in this embodiment both parts 1 , 7th consist of polyhydroxybutyric acid.
