Description

Description Initially, the propagation by cuttings, which is common in horticulture and in plant propagation, is explained in detail. In particular, it describes how cuttings are currently propagated in (commercial) horticulture and what negative parameters occur today. It will explain how this achievement works, why it works, and what areas of application are appropriate for it. In part, it will also be discussed what could be done better in an industrial manufacturing, but for reasons of cost and partly due to lack of technical possibilities, so far not been made.

As cuttings are called the fresh, young shoots of plants that are removed from the same, in order to root them and to use a new, own plant. You cut them - depending on the plant very different - between 5 and 20cm in length - from the new growth of a plant down.

In the case of cuttings, a distinction is made in principle between three different types, subdivided according to the "plant material hardness", and no distinction is made between where on the plant and how a cuttings are taken, that is, for example, as apically, terminally or laterally removed cuttings or according to other distinguishing criteria, which could be used.

One distinguishes softwood cuttings, semi-hardwood cuttings and hardwood cuttings. The latter are then so-called hardwoods, which are not usually referred to as cuttings and not used as such.

You can use full woody branch pieces here. These are e.g. taken from trees and sometimes even need a few months to root. These form or their use is not the subject of the present invention per se.

Semi-hard wood cuttings have already a woody part in the tissue, but are partly still green, of young growth and usually have leaves. This type of cuttings is particularly in question to be rooted according to the invention. It should be noted, however, that these types of cuttings are not always suitable for propagation according to the invention described in more detail below.

However, softwood cuttings are practically always suitable for use in accordance with the present invention. By this one understands very young, still "krautige" impulses. Herbaceous cuttings can be taken from virtually any plant from which you can even take cuttings, so for example, cacti are out of the question, but also trees, which are usually also propagated via plywood.

Just take fresh or new shoots that are not yet or at most only partially wooded, but no "old" branches, branches od. Like ..

About softwood cuttings are typically propagated especially fast-growing plants and in particular special breeds (= Variegatas), which would lose their seeds, ie in generative propagation, so the desired, typical for them characteristics. In some plants, different variants can be practiced, depending on individual needs and / or cost-effectiveness.

Plants capable of propagation via softwood cuttings include hemp, certain herbs, e.g. colorful basil or the like, partly tomatoes, over the removed Geiztriebe, roses, etc ..

In short, the cuttings industry is widespread and therefore very versatile, so of course not everything can be listed here.

It should be noted at this point that today mother plants, ie plants that are only pulled to regularly take cuttings from them for rooting, usually "elsewhere", ie. in Africa, for example in Kenya. The branches are then taken there locally and flown unrooted to Europe and / or the United States. Only then are they rooted, so as not to have to carry unnecessary weight, ie substrate.

The labor-intensive rooting process itself is thus usually carried out in first-world countries with their high labor costs. So higher personnel costs are spent in order to save in return high transport costs. Thus, the present invention is of high interest insofar as it is capable of significantly reducing human labor and thus personnel costs.

Usually softwood cuttings, after the branch to be rooted, branch od. Like. Has been removed from a plant, possibly treated with hormones, and has been inserted into the substrate, placed in a (mini) greenhouse. Such is according to American standard measures: 28x54cm2 large. European greenhouses are slightly different in size, but otherwise there is no significant difference between these greenhouses.

A greenhouse is necessary to provide an ambient humidity of 80 to 100%. This is necessary so that the cuttings do not transpire - that is, they can not release moisture via their leaves to the environment. Otherwise he would wither, suffer stress, and eventually die, depending on what happens next.

As a rule, softwood cuttings can only be grown in greenhouses because they release more moisture than they can absorb - as a result of their missing roots.

A plant must constantly pump water or aqueous solutions "from the bottom up" to be able to stand upright (turgor pressure). If the humidity around the plant is too low, it will release the water to the environment, and in that case it will have to pump up and pump up new water constantly, which will constantly release it as a vapor to the environment. This process in the plant requires a lot of energy, about 70-80% of the total energy needs of a plant.

If you raise the humidity to 100%, the plant can not transpire, so therefore does not need to constantly "pump new water" and thus consumes less energy for this process. The plant or the branch thus remains more energy to form roots, which is indeed desired.

A standard greenhouse causes a lot of staff. It is necessary to ventilate the same regularly, sometimes several times a day to regulate the humidity, e.g. manually by means of flaps and slits, and there is also an increased risk of mold growth if the humidity is too high.

It has now been considered considerations to meet the circumstances described for the first time so that it would be possible to practically prevent the described cost of pumping up the water in the cuttings by the cuttings not vertically but horizontally "stands" So place the plant as if it were lying. This would save the plant a great deal of the energy required to "stand upright" and pump the water upwards against gravity.

Reference may be made to the existing state of the art: US 2005166452 A1 and US 5555676 A describe devices and methods for the vegetative propagation of plants by rooting of plant cuttings in a supplied with water or nutrient solution plant substrate, wherein plant cuttings in (Round) recesses of a jacket tube of a vertically arranged tubular body are inserted horizontally, the cavity is filled with substrate, which is supplied with nutrient solution from a container arranged above, collected at the lower end in a container and by pump back into the upper container is encouraged.

In US 2005166452 A1 and JP 2000093026 A, instructions are given to one of ordinary skill in the art to provide adequate lighting equipment for the plants.

The invention is now a new method for promoting the growth of plants in a supplied with water or aqueous nutrient plant substrate under

Action of light, - in each of which - in a plurality of - preferably substantially along at least one vertical or a Wedelspirale at intervals - under or over each other arranged recesses of the shell of at least one from above with water or an aqueous nutrient solution, arranged vertically, hollow, elongated tubular body, in the cavity of the same protruding and outwardly a substantially vertical outer surface having substrate body substantially perpendicular to the outer surface or to the outer surface of the tubular body is arranged in each case a plant substantially horizontally, - wherein furthermore the / collected after loading of the individual substrate body at the lower end of the at least one tubular body effluent or dripping water / nutrient solution in a container and returned to the water / nutrient solution supply or in their storage container, preferably zurückgepumpt example, and the plants from the side with daylight and / or artificial light will be light-supplied, which is characterized in that - for the vegetative propagation of plants by rooting plant cuttings - in the substrate body in each case an unrooted plant cuttings is inserted horizontally, - that the taking place from above the at least one tube body supply of the subordinate arranged substrate body in the tube body supplying water or nutrient solution is made continuously or intermittently, in particular in drop form, said or within the distances between the substrate bodies freely downwards dripping, in particular dripping, water or nutrient solution receives oxygen from the surrounding air and - that the plant cuttings are light-supplied until reaching a respective intended or desired rooting degree.

In the present invention is a method and subsequently to an apparatus with which or one cuttings in a very small space, ie in particular on a small footprint, because in this case the height is used, and with very little labor input , And possibly also without special technical, so in particular electrical, devices, attract and rooted.

You could also use it to seedlings up to a certain size. However, this is not the actual goal of the invention, because in this case the advantages would be rather low and additional details would have to be adapted.

Plants and also truncated, living branches respond to light and gravity to orient themselves up / down, due to phototropism and gravitropism. The orientation of the tip of the plant, always depends on the incident light. Auxin, a plant hormone, is among others. responsible for the cell extension. It is destroyed or destroyed by light, and so there is no or only minimal cell stretching at a point where light shines. Thus, when illuminated in particular evenly, the plant grows evenly in the direction of light. This explains why the plant in the rooting technique according to the invention grows "straight ahead", ie horizontally and not "around the curve".

Namely, it is the lighting just not above the plant, but essentially laterally "next to" her and / or positioned "in front of" her.

Also, a non-optimal illumination only by passive sidelight can be done by lamps in a large greenhouse, which in itself. below the pipe body has illuminated other plants.

Optimum illumination would be e.g. certainly by means of next to and / or previously hung light bar in each meaningful intervals, which are clear to any gardener reached.

Optionally, also in a saving manner, the new, provided with cuttings tube body simply positioned on a bright window, in particular hung, be, what an artificial, so in particular electrical lighting spared. In any event, the lighting is much more optimal when hanging the new rooting device against a window or transparent greenhouse, as if you were placing a standard greenhouse with cuttings on the ground near a window.

When the tubular body is substantially "perpendicularly" aligned with the substrate, and the cuttings are substantially "horizontal", as compulsorily provided according to the invention, they all grow as they should, ie, forward to the light, thus horizontal and now". If they stood on the floor in a miniature greenhouse, they would grow towards the light, ie to the light-emitting window, so "oblique" or with curvature.

As far as the actual operation is concerned, practically no limits are set here, for example, operate the new rooting system with pumps, but certainly without such. One can run the pump permanently or even just e.g. regularly periodically. Permanently or regularly periodically, e.g. at intervals of 30 minutes, preferably because the water or nutrient solution in the substrate bodies, e.g. Rock wool wedges do not "stand". If the water in the individual substrate body "stands" too long, ie is not exchanged for new, ultimately too little oxygen may be present and the cuttings begin to mold.

In order to ensure sufficient oxygen in the medium, it is therefore advantageous to replace the water or the nutrient solution either constantly, or at least regularly, by new, oxygen-rich water.

It is particularly favorable if the water, in particular the nutrient solution, drips "from top to bottom" or flows slowly. It is sufficient if constantly water, which is possibly enriched in the collecting container also with oxygen, e.g. by means of an air pump with atomizer, as for aquariums, from the top down through the substrate body passes vertically. Oxygen enrichment can certainly be ensured by adding small amounts of hydrogen peroxide in the water or in the nutrient solution. It is favorable if the water or the nutrient solution does not constantly flow through, but drips through it. For this, a conventional irrigation system, e.g. a "Gardena Micro Drip" system.

Above the vertically arranged substrate bodies, for example, a dropper is placed, e.g. 2 l / h or 4 l / h dropper. "Drop" is therefore favorable, since it comes here, so to speak, to small breaks in the irrigation, within which air in the substrate medium and is absorbed. Any drop of water dripping down from a rockwool body sucks the same volume of air into it. Thus, a constant oxygen enrichment or Nachnachreicherung is ensured in the substrate body.

In addition, many small drops that constantly fail one at a time have a larger surface area than water that runs permanently. This larger surface in turn leads to a larger air, so ultimately oxygen uptake.

One can thereby enrich the oxygen content of the nutrient solution by means of air pumps, or e.g. Spare adding hydrogen peroxide.

Oxygen in the substrate supply medium is essential for rooting. As long as enough oxygen is available, the substrate body used can certainly be permanently "wet".

A "dripping" of water / nutrient solution thus guarantees, despite the absence of other technical facilities, still enough oxygen in the substrate body. Thus, in simple cases it is possible to simply place a water tank above the substrates, e.g. is replenished only once a day, instead of a pump that pumps the nutrient solution back into the drippers from the bottom of the collection container.

At this point, a quite simple version of the invention, how to use as a private household the new cuttings rooting system - e.g. instead of a miniature greenhouse on the windowsill - can use if you want to root cuttings. For this one needs only one tube, e.g. made of plastic, with the substrate bodies, below the same a collecting container, such. a bucket and above the tube a water-loaded plastic bottle, e.g. with a dropper that is simply screwed onto the bottle.

If the cutting is once placed in the substrate body in the tube, these can for example just optimally put the same on a windowsill, virtually no further care is necessary. Only the liquid, so the nutrient solution in the bottle must be refilled if necessary.

With regard to various variants, improvements and / or optimizations of the present invention, the following is to be explained in more detail: [0031] In particular in the sense of the economical handling of the water / nutrient solution used for moistening the substrate body, it is advantageous to if the water / nutrient solution flowing out of the bottom of the tubular body after being fed to the individual substrate bodies is collected in a container and pumped back into the water / nutrient solution feed or into its storage container.

As cuttings according to the invention preferably soft or semi-hard wood cuttings are used.

It is advantageous, in particular with regard to rooting of the cuttings, if it is ensured that the water / nutrient solution to be supplied is supplied with oxygen or is added to the same H 2 O 2.

Another essential object of the invention is a novel device for the vegetative propagation of plants by rooting of plant cuttings in a supplied with water or aqueous nutrient plant substrate under the action of light, for carrying out the method according to any one of claims 1 to 3, which is formed with at least one vertically arranged tubular body, wherein the tubular body has in its jacket at least one row, preferably a plurality of rows of substantially along a vertical or spiral spiral arranged below each other recesses, in each of which in the Cavity of / the tubular body / s projecting substrate body is introduced with substantially vertically oriented outer surface and the substrate body from above with water or aqueous nutrient solution can be supplied, and below the tubular body, a container for collecting or from the / desselb is arranged after moistening the substrate body with water or nutrient solution, from which at least one line with pump for pumping back of or collected there water or nutrient solution to or into the means for the supply of the same or emanates to the substrate bodies, which characterized in that - substantially vertically to the outer surface of the substrate body, in each case a plant plug in a substantially horizontal position can be inserted, - that above the tubular body / s, preferably a plurality of juxtaposed, optionally bound together, such tubular bodies, a programmable, Device for the supply of water or aqueous nutrient solution for applying or moistening each of the substrate body projecting into the cavity (s) of the hollow body (s) with water or nutrient solution in continuous or intermittent form, in particular drop form is ordered and - that for rooting the plant cuttings they are illuminated from the side or lichtversorgbar.

As regards the geometric shape of the individual tubular bodies and their recesses, it has proven particularly useful if the individual tubular body has substantially rectangular or square, circular or oval cross section and / or the recesses in the shell of the same substantially circular, have oval, square or rhomboid basic shape.

With regard to the shape of the substrate body is to be noted that it is advantageous if the substantially cylindrical, truncated cone, truncated pyramid, cuboid or cube shape having substrate body made of plant-compatible mineral or rock wool.

Optimum results in the propagation of cuttings can finally be achieved if the / the vertically arranged / n tubular body with the inserted into the substrate body in the horizontal position plant cuttings from the side acting daylight and / or artificial light, in particular from one of the longitudinal / the tubular body / s arranged at a distance from the same, or optionally flat, light-emitting light source can be exposed.

In the sense of a highly energy-saving and at the same time high yields of rooted cuttings performing cuttings propagation, a device has been found in which a plurality of vertically disposed tubular bodies are arranged substantially raster-shaped with, preferably equal, distances from each other, and that in the spaces between the tube bodies a plurality of, in, preferably the same, distances from the tubular bodies, under or superimposed lamps or light sources, preferably of each other crossing and each substantially horizontally arranged fluorescent tubes are arranged.

It is particularly advantageous if a plurality of vertically arranged tubular bodies are arranged substantially grid-like with, preferably the same, distances from each other, and that in the spaces between the tubular bodies a plurality of, in, preferably the same, distances from the Tubular bodies, substantially parallel to the tubular bodies and substantially the same length as the same fluorescent tubes are arranged.

Not least object of the invention is the use of the device according to the invention in its variants for the new method for propagating cuttings in its variants.

In addition, it should be emphasized that according to the invention in comparison to previously common "horizontal" mini-greenhouses, the new device takes up very little space. The "depth" may here be e.g. 10cm, but it would go a little less. If you take the plant size, ie about 10 to 20cm, so the device is as deep as a previously common greenhouse is wide, so about 30cm. For example, a prototype of the device according to the invention 32 tubes with e.g. each 39 holes. This allows a total of 1248 plants to be grown on the surface of four small greenhouse hitherto customary. And this number can still increase a lot in accordance with optimal utilization of room height and Ausneh- mung or hole density, ie number of recesses of a tubular body. In general, a lot more cuttings can be rooted at once in high, available rooms.

Finally, the essential features and advantages of the present invention are explained once again: [0043] High number of cuttings to be rooted on a small footprint. After plugging to the roots of the cuttings, virtually no further care is necessary, only the nutrient solution is to control and renew if necessary.

In winter, it may be necessary or beneficial to heat the water or the nutrient solution and possibly to cool it in the summer. Every greenhouse manager should be familiar with this - corresponding refrigerators are available in the market for e.g. hydroponic plants.

In softwood cuttings can be dispensed with a cover for raising the humidity, since the cuttings must indeed maintain the turgor pressure, but this only horizontally and not perpendicular to gravity.

It is possible to offer the end customer a replacement for a hitherto conventional room greenhouse, or you can use the invention commercially on a large scale, as it is easily expandable.

It may e.g. a "wall" of juxtaposed pipes are built in any dimensions and these can be fitted so to speak, "double", so that such a tubular body wall front and rear, so on both sides, plantable.

With an appropriate distance, the next two-sided or double wall of tubular bodies can be positioned, wherein between the two walls, a preferably flat, lighting can be arranged.

The walls may further be e.g. Sliding on rails or rolling, so you can pull them out like a curtain to work on them.
