Abstract
Abstract The invention relates to a water-absorbing porous product made of water-absorbing mineral fibrous material for the cultivation of plants. Said product comprises water-repellent oxygen-storing elements which are able to release oxygen in a delayed manner to a liquid sucked up into the porous product. Said elements preferably form at least one layer (2) between two layers (3,4) of water-absorbing mineral wool. The layer of water-repellent oxygen-storing elements is preferably at least partially in contact with the outside air. The invention also relates to a method for the cultivation of plants using the water-absorbing product according to the invention.

Claim 1
Independent Claim
34 words
Water-absorbing porous product made of water-absorbing mineral fibrous material for the cultivation of plants, preferably in the form of a block, characterized in that the porous product contains at least one water-repellent oxygen-storing element.
Claim 2
Dependent Claim
34 words
Water-absorbing porous product made of water-absorbing mineral fibrous material for the cultivation of plants, preferably in the form of a block, characterized in that the porous product contains at least one water-repellent oxygen-storing element.
Claim 3
Dependent Claim
32 words
Water-absorbing porous product according to claim 1, characterized in that the water-repellent oxygen-storing element is able to release oxygen in a delayed manner to a liquid sucked up into the porous product.
Claim 4
Dependent Claim
34 words
Water-absorbing porous product according to claim 1 or 2, characterized in that oxygen-storing preferably also porous, water-repellent elements form at least one layer in the porous product between two layers of water-absorbing mineral wool.
Claim 5
Dependent Claim
45 words
Water-absorbing porous product according to claim 1-3, characterzed in that several layers of oxygen-containing water-repellent elements, situated at a distance from each other are incorporated in the porous product, preferably the distance between layers of water-repellent elements being matched to the plants to be cultivated.
Claim 6
Dependent Claim
22 words
Water-absorbing porous product according to claims 1-4, characterized in that layers of water-repellent elements are situated at equal distances from each other.
Claim 7
Dependent Claim
45 words
Water-absorbing porous product according to claims 1-5, characterized in that the volume of the oxygen-storing water-repellent elements provided in a layer increases in the direction of the surface which is the last to come into contact with the roots of a plant to be cultivated.
Claim 8
Dependent Claim
31 words
Water-absorbing porous product according to claims 1-7, characterized in that the number and the thickness of the successive layers of oxygen-storing elements is chosen depending on the plant to be cultivated.
Claim 9
Dependent Claim
30 words
Water-absorbing porous product according to claim 1 or 2, characterized in that the porous product comprises groove-like recesses which contain at least in part oxygen-storing, preferably also porous, water-repellent elements.
Claim 10
Dependent Claim
21 words
Water-absorbing porous product according to claims 1-8, characterized in that the water-repellent porous elements consist of water-repellent flakes of mineral wool.
