Abstract

Abstract Translated from French L'invention est relative à de nouveaux substrats pour la culture hors-sol. The invention relates to new substrates for above-ground cultivation. Les substrats sont formés de feutre de fibres minérales pré­sentant un gradient d'hydrorétentivité tel que cette dernière décroit suivant le sens de la gravité. The substrates are formed from felt of mineral fibers having a hydroretentivity gradient such that the latter decreases according to the direction of gravity. Le substrat I présente un gradient d'hydrorétentivité dû un gradient de finesse des fibres tel que le diamètre moyen des fibres croit dans le sens de la gravité. Dans le substrat II, le diamètre des fibres varie en sens inverse. La rétention d'eau est plus élevée dans le substrat I que dans le substrat II. The substrate I has a hydroretentivity gradient due to a fineness gradient of the fibers such that the average diameter of the fibers increases in the direction of gravity. In substrate II, the diameter of the fibers varies in the opposite direction. Water retention is higher in substrate I than in substrate II.
