Patent

CA 2495900

The invention provides a method of growing at least one plant (1), preferably a large number of plants, in which a plant is positioned for growth in a first growth substrate (2) which has a first water uptake capacity and a first sinking time S1, and the first growth substrate (2) is in fluid communication with a discrete second substrate (4) is mineral wool of density 40 to 100kg/m2 and which has a second water uptake capacity which is less than the first water uptake capacity and a second sinking time S2 and the value of S1 is greater than the value of S2, and during growth the second substrate is flooded with water at intervals. Preferably growth is under conditions of drought stress and/or nutrient stress. The invention also provides a plant growth environment such as a filled pot (3) comprising the first and second substrates in fluid 20 communication.

L'invention concerne un procédé de croissance d'au moins un végétal (1), de préférence un nombre élevé de végétaux. Selon ce procédé, le végétal est disposé de manière à croître dans un premier substrat de croissance (2) qui présente une première capacité d'absorption d'eau et un premier temps S1 de chute. Le premier substrat de croissance (2) est en communication fluidique avec un second substrat discret (4) consistant en de la laine minérale d'une densité comprise entre 40 et 100kg/m?2¿ et qui présente une seconde capacité d'absorption d'eau inférieure à la première capacité d'absorption d'eau et un second temps S2 de chute. Au cours de la croissance, le second substrat est imprégné d'eau par intervalles. De préférence, la croissance se fait dans des conditions de stress de sécheresse et/ou de stress nutritif. L'invention concerne aussi un environnement de croissance des végétaux tel qu'un récipient rempli (3) comprenant le premier et le second substrat en communication fluidique.
