Verbessertes Substrat für die erdlose PflanzenkulturImproved substrate for soilless plant culture
Die Verwendung von synthetischen Schaumstoffen als Substrat für die erdlose Pflanzenkultur ist bereits bekannt. So m The use of synthetic foams as a substrate for soilless plant culture is already known. So m
beschreibt zum Beispiel die deutsche Patentschrift 1 018 077 die Verwendung von Kunstharzschaumstoffen aus Aminoplasten, Phenoplasten oder Melaminharzen als Trägerschicht für den erdlosen Pflanzenanbau. Auch die Verwendung von Polyurethanschaumstoffen für dieses Einsatzgebiet ist bereits bekannt (deutsche Patentschrift 1. 299 662).For example, German patent specification 1 018 077 describes the use of synthetic resin foams Aminoplasts, phenoplasts or melamine resins as a carrier layer for soilless plant cultivation. Also the use of polyurethane foams for this area of application is already known (German patent specification 1,299,662).
Wie nun überraschend gefunden wurde, kann die Ausbildung von Wurzelanlagen, die Wurzelbildung (Bewurzelungsrate) und Wurzelausbreitung bei Stecklingen sowie die Keimwurzelbildung aus keimenden Samen in derartigen Schaumsubstraten wesentlich erhöht werden, wenn durch eine Dunkel-bzw. Schwarz- M As has now surprisingly been found, the formation of root systems, the root formation (rooting rate) and root spread in cuttings as well as the radicle formation from germinating seeds in such foam substrates can be significantly increased if a dark or. Black- M
färbung der Schaumsubstrate der Lichteintritt in den Wurzelraum der Pflanze vermieden wird. Die Ursache für diesen überraschenden Effekt liegt (offensichtlich darin, daß eine negative Beeinflußung der wurzelfördernden Wirkstoffe durch Lichteinwirkung ausgeschlossen wird.coloring of the foam substrates prevents light from entering the root space of the plant. The cause of this surprising effect (obviously in the fact that a negative influence of the root-promoting active ingredients by exposure to light is excluded.
Gegenstand der vorliegenden Erfindung ist somit ein rsrbessertes Substrat für die erdlose Pflanzenkultur, dadurch gekennzeichnet, daß es aus einem dunkel vorzugsweise schwarz eingefärbten hydrophilen offenzelligen Schaumstoff der Dichte 8-50 kg/m' besteht. The present invention is thus a rsrbessertes substrate for soil-less plant culture, characterized in that it consists of a dark, preferably black-colored hydrophilic open-cell foam of density 8-50 kg / m '.

Die Herstellung der erfindungsgemäßen, verbesserten, das heißt dunkel oder schwarz eingefärbten Schaumsubstrate kann sowohl durch nachträgliche Binfärbung der fertigen. Substrate zum Beispiel durch Tränken mit einer Farbstofflösung oder auch durch Mitverwendung von dunklen Farbpigmenten bei der Schaumstoffherstellung erfolgen. Das erfindungsgemäße Prinzip der Dunkelfärbung läßt sich bei beliebigen Schausubstraten anwenden. Besonders leicht zugänglich sind jedoch dunkel bis schwarz eingefärbte Polyurethanschaumsubstrate, da es hierzu genügt eine der zur Herstellung des Schaumstoffes verwendeten Komponenten mit einem geeigneten Pigment vorzugsweise Ruß anzupasten. So kann zum Beispiel auf einfache Weise ein schwarz eingefärbtes Polyurethansubstrat hergestellt werden, indem die entsprechend den bekannten Methoden der Polyurethanschaumstoff he rs te llung verwendete Polyolkomponente mit Ruß vermengt wird und anschließend in bekannter Weise mit Polyisocyanaten, Treibmitteln, Stabilisatoren, Katalysatoren und gegebenenfalls weiteren Zusatzstoffen zum Schaumstoff umge-r' setzt wird.The production of the improved, that is to say dark or black colored, foam substrates according to the invention can be done both by subsequent coloration of the finished. Substrates, for example, by soaking them with a dye solution or also by using dark color pigments during the production of foam. The principle of the dark coloration according to the invention can be used with apply any display substrate. However, polyurethane foam substrates from dark to black are particularly easily accessible, since one of the components used to produce the foam is sufficient for this purpose to paste preferably carbon black with a suitable pigment. For example, a black colored Polyurethane substrate can be made by applying according to known methods of polyurethane foam Polyol component used in the manufacture mixed with carbon black is and then in a known manner with polyisocyanates, blowing agents, stabilizers, catalysts and if necessary, other additives to the foam is set.
Als Pflanzensubstrat bevorzugt geeignet, sind dunkel oder schwarz eingefärbt© offe&zellige hydrophile Polyurethanschaumstoffe der Dichte 6 - 50 vorzugsweise 10. - 15 kg/m. Preferred as a plant substrate are dark or Dyed black © offe & cellular hydrophilic polyurethane foams with a density of 6 - 50, preferably 10 - 15 kg / m.
Pur die Praxis bevorzugt geeignete erflndüangsgemäße Schaum-, substrate sind solche, deren Oberfläche durch einen für die Pflanze leicht durchdriaglichen, di© Verdunstung von Masser stark vermindernden Kunststoff», Kautschuk- oder Paraffinfilm versehen ist.In practice it is preferred to use suitable foam, substrates are those whose surface is covered by one for the Plant easily permeable, ie evaporation of mass strongly reducing plastic, rubber or paraffin film is provided.
Bevorzugt werden die erfindungsgemäßen,, verbesserten Schaumsubstrate in Form von würfel- oder quaderförroigem Körpsra eingesetzt,, die auf Tabletts angeordnet sind, deren Seitenwände "dem erforderlichen Wasseranstiegsvermögan im Se&aumstoff angepaßt sind.The improved foam substrates according to the invention are preferred in the form of cubes or cuboid bodies used ,, which are arranged on trays, the side walls "the necessary water-rising capacity in the seam material are adapted.
