PATENT CLAIMS

1. Means for rational planting of lawn and / or garden areas, in the form of a dry fiberboard that disintegrates when watered, and in which plant seeds and nutrients for the plants sprouting from these seeds are contained.

2. Composition according to claim 1, characterized in that the fiberboard consists of natural organic fibers, such as those made of wood, straw or peat garbage, or of a mixture of such fiber materials.

3. Composition according to claim 1 or 2, characterized in that the fiberboard contains seeds of lawn, of jewelry or of useful plants.

4. Composition according to one of the preceding claims, characterized in that the grains of the plant seed in the fiberboard are present in a homogeneous distribution, in the form of an intermediate layer or in the form of separate rows.

5. Composition according to one of the preceding claims, characterized in that the fiberboard has a density of at most 250 g / dm3.

6. A process for the preparation of the agent according to claim 1, characterized in that the plant seed to be introduced into the fiberboard is never exposed to a temperature of more than 50 ° C. during the manufacture of the fiberboard.

7. The method according to claim 6, characterized in that during the production of the fiberboard the plant seeds are not exposed to the temperature of 40 ° C or at most only briefly.

For planting lawns in the well-known way, the grass seed is sown on the prepared soil and then watered. One of the disadvantages of this method is that a large part of the seeds remain on the surface of the soil, so that the seeds flow together during irrigation, which can easily lead to an uneven distribution of the lawn after it has grown.

Another disadvantage of this method is that the seeds lying on the surface of the ground are a popular and easily accessible feed for birds, so that a larger amount of seeds than necessary must be sown to compensate for the expected loss. With a large number of birds, for example with flocks of migratory birds in autumn, an entire sowing can be completely destroyed in extreme cases.

Another disadvantage of this conventional method is that, in unfavorable cases, growing weeds can become so prevalent that the sown grass is hindered in its growth and is partially or completely suffocated.

Pre-germinated turf is already commercially available in the form of rolls or flat pieces, the disadvantages of which, however, are that it is relatively heavy on the one hand and is therefore difficult and difficult to transport, and on the other hand it is easily vulnerable to storage, which makes it more difficult often result in long transport routes for the customer from the manufacturer to the place of use.

It is an object of the present invention to provide a means for rational planting of lawn and / or garden areas which does not have the disadvantages described above.

This object is achieved by the means according to the invention and defined in claim 1.

The dry fiberboard serving as the basic substance for the agent according to the invention is preferably formed from organic natural fibers, for example those made from wood, straw, peat garbage or the like, or from a mixture of such fibrous materials. Such natural fibers and mixtures thereof obtained from trees, bushes, grasses, peat garbage and the like are easily decomposable, in contrast to tree bark, which also contains undesirably high proportions of resin compounds. The agent according to the invention expediently has a low density of at most 250 g / dm 3.

Even before germination, the dry fiberboard provides a firm anchor for each individual grain, which prevents the seeds from moving freely during watering. At the same time, the fiberboard generally provides a protective and pre-germinating environment. During the critical period of germination, the fiberboard inhibits weed growth.

The agent according to the invention is light in weight and can therefore be transported easily and without special precautions. The light weight also creates ergonomic advantages during planting, especially when planting lawn on steep ground, for example on dams and road sides.

For the sale, the agent according to the invention can easily be stored in store rooms of the sales shops.

The preparation of the agent according to the invention is carried out in the simplest and most convenient manner by the conventional method for producing insulation board and using a conventional device for carrying out this method. The subject matter of the invention is explained below, for example.

The respective plant seed can be introduced into the fiberboard during its production by either mixing it with the fibrous pulp before it emerges on the paper machine screen or sprinkling it on a still moist fibrous layer and then covering it with another fibrous layer. After this latter process step, it is possible, depending on the particular type of seed, to introduce the seed grains into the fiberboard such that they are present at a predetermined distance from the surface to be planted when the fiberboard is laid out. When the plant seeds are mixed with the fiber pulp before they emerge on the paper machine screen, a dry fiber board is finally obtained, in which the seeds are homogeneously distributed throughout.

According to a further embodiment, the plant seeds can also be introduced into the fiberboard in separate rows, which is particularly expedient for the planting of useful plants, such as vegetables, or of ornamental plants, such as flowers and the like.

In order to create an environment that supports the pre-germination and growth for the seeds in the dry fiberboard, they are added to suitable nutrients for the plants sprouting from the respective seed type. This addition is expediently carried out in the production of the fiberboard by mixing with the fibrous pulp prior to its emergence on the paper machine sieve, the solubility rate of which can be adjusted by selecting powdered nutrient substances of coarser or finer grain size. The nutrient substances are advantageously embedded in a medium which retards the solution, so that their dissolution takes place in a known manner from the solid body via a gel to the liquid state.

When using fibers that have poor adhesion to one another even after pressing, the mechanical strength of the fiberboard can be significantly improved by adding an environmentally friendly and water-soluble sizing agent, such as starch, cellulose glue, casein or the like, to the fiber pulp before it comes onto the paper machine screen . The desired density of the dry fiberboard of at most 250 g / dm3 can be adjusted by appropriate pressure during the manufacture of the fiberboard.

When manufacturing the fiberboard, it is essential to ensure that the plant seeds to be introduced into the panel are not exposed to a temperature of more than 50 ° C, preferably not or only briefly

of more than 40 ° C. By adhering to this upper temperature limit, which can of course vary depending on the type of seed, the germination capacity of the seed is retained.

Since the temperature at which the lignin present in wood fibers could undergo crosslinking reactions is not reached during the production of the agent according to the invention, a dry fiberboard of the specified low density is ultimately obtained, which disintegrates to an appropriate extent when irrigated and thereby bonds well to the soil, so that favorable conditions for the introduction into the soil are created for the germinating plant roots.
