摘要

1. The substrate intended for use as a substrate for growing crops, characterized in that it contains: the first part, which is the skeleton of the substrate and constituting more than 70% of the total volume of the substrate, composed of particles Rmkm larger than 100 microns, and the combination of these particles consists of solid particles P and / or elastic particles P, and the volume fraction PV of these elastic particles is from 0% to 100% by volume of this first part; the second part of the corpuscular elements with a size of less than 100 μm, and this part is from 0 up to 450 g / l of the aforementioned substrate; a third part, comprising from 0 to 200 g / l of the aforementioned substrate, consisting of thin fibers from 3 mm to 100 mm long and a diameter of from 5 μm to 35 μm; a fourth part, from 0 to 200 g / l of the aforementioned substrate, consisting of other elongated and / or surface inclusions, at least one of the sizes of each of these elongated and / or surface inclusions significantly exceeds the particle sizes of the first part, and the total amount of the third and fourth parts exceeds 0 5 g / l of the mentioned sub stratum. 2. The substrate according to claim 1, characterized in that the combination of all particles, the size of which is more than 180 microns and less than 100 microns, is less than 1000 g / l of the substrate. The substrate according to claim 1, characterized in that the volume fraction of PV elastic particles is less than 5%, the sum of the dose D of thin fibers and the dose D of all other inclusions of the fourth part exceeds 0.5 g / liter of substrate and 20 g / liter of substrate. The substrate according to claim 1, characterized in that the volume fraction of PV elastic particles P is more than 5%, the sum of the dose D of thin fibers and the dose D of all other inclusions of the fourth part exceeds 1 g / liter of substrate.
