SK284647B6 - Rolled lawn without soil and method for producing thereof - Google Patents

Abstract

The rolled lawn without soil has a weight 9 kg/m2 maximum, preferably 6 kg/m2 and/or comminuted rape stems, maize stalks and/or sunflower stems as the substrate as the substrate. In order to produce a rolled lawn, straw, rape stems, maize stalks and/or sunflower stems are comminuted to form coarse chips and these are mixed with up to 50 percent by mass, preferably up to 30 percent by mass, of sawdust, in relation to the overall mass. The resulting substrate is positioned on topsoil, whereupon rolled lawn seeds are applied and then watered.

Description

Technical field

The present invention relates to a roll-free turf without soil and to a method for producing a roll-free turf without soil.

BACKGROUND OF THE INVENTION

Soil-free rolled lawn and a method for its production have already been proposed in AT-1577 U. According to the method proposed therein, sawdust is applied to humus ground, then the seed of a rolled lawn is applied, then sawdust again and finally irrigated.

Regardless of the fact that this method is technically relatively easy (neither a greenhouse nor a irrigated fleece mat, as is often the case in the prior art), a particular advantage can be seen in the fact that the rolled lawn so produced is considerably lighter than usual . A roll lawn grown in the soil has a weight of approximately 25 kg / m ² , a roll lawn with sawdust only approximately 12 kg / m ² .

The object of the present invention is to produce a rolled lawn which is even lighter than a sawdust rolled lawn and which is just as cheap or even cheaper.

SUMMARY OF THE INVENTION

This object is achieved by a roll turf according to the invention which has a mass of not more than 9 kg / m ² , in particular not more than 6 kg / m ² , and as substrate contains crushed straw and / or crushed rapeseed, corn crops and / or sunflower byle. A particular advantage is the low weight. This reduces the transport cost approximately four times (calculated per m ² ). Even when straightening freshly cut lawn bales on pallets, four times the time is saved and the personnel costs are reduced accordingly. When moving, the time saving is approximately 50%, since significantly more bales can be transported to the storage location in the sliding cabinet. However, the substrate used is also preferred. With appropriate irrigation, it changes over time to humus (compost), so the new lawn remains beautifully green for about 7 to 9 months without fertilization.

Compared to conventional lawns with soil, it is furthermore advantageous to save humus soil. In conventional lawns with soil, approximately 1.5 cm of soil is cut together each time you cut a piece of lawn (ie usually once a year), so that after about 15 years, vandalism will develop on humus soil, so that nothing can be grown in this field anymore. With the method according to the invention, cutting a piece of lawn also saves considerably more machine: instead of 10 to 12 cutting blades per month, only 2 cutting blades are needed per year. In addition, the diesel consumption of the machine is considerably lower.

This object is further solved by the process for the production of a soilless lawn roll according to the invention, which consists in that the straw, rapeseed, corn and / or sunflower crops are crushed into a mower and mixed with up to 50% by weight, in particular 30% by weight, sawdust, based on the total weight and the substrate thus formed, is applied to the humus ground, then the grass seed of the rolled lawn is applied and then irrigated. According to the invention, therefore, only small sawdust is applied. The substrate consists mainly of 2 waste cut to the chopper, namely straw, rapeseed, corn and sunflower seeds, which have been crushed into the chopper in the mowing plant. This disposal is partly paid by farmers who have to dispose of this waste. This results in the cost of the substrate being worn only by the mowing machine and sawdust, but the proportion may be relatively small, typically 15% by weight.

This is why this substrate for the production of rolled turf is a very valuable means: this can only achieve a weight of 4.5 to 5 kg / m ² ! Typically, a 3 cm thick substrate layer is applied.

It is expedient if crushed shrubs and / or shrubs and / or coniferous wood are added to the mower, which are produced as waste when cutting trees. In this way, additional waste can be usefully recovered.

According to one embodiment of the present invention, after the substrate layer has been applied, it is mixed with humus earth by means of rotary harrows. This has the advantage that the lawn will take root faster. However, this is achieved with a higher roll lawn weight of approximately 8 kg / m ² . Typically, 3 cm of substrate is milled into 2 cm of soil.
