Abstract

La présente invention appartient au domaine technique des dispositifs de culture de plantes, et concerne un dispositif de culture ramifié, le dispositif comprenant un bâti de culture et de multiples rainures de culture. Le bâti de culture comprend de multiples étagères hydroponiques disposées de haut en bas. Les rainures de culture sont disposées de manière coulissante sur les étagères hydroponiques. Chaque étagère hydroponique est pourvue d'un passage de sortie d'eau et d'un passage d'entrée d'eau. Une ouverture d'entrée d'eau est disposée sur le passage d'entrée d'eau. Des rainures d'entrée d'eau et des rainures de sortie d'eau sont disposées dans les rainures de culture. Les rainures de culture ont un état d'afflux d'eau dans lequel les rainures d'entrée d'eau sont reliées à des voies d'eau d'ouverture d'entrée d'eau, et un état de reflux d'eau dans lequel les rainures de sortie d'eau sont reliées aux voies d'eau d'ouverture d'entrée d'eau. Les rainures d'entrée d'eau et les rainures de sortie d'eau sont agencées dans une direction de coulissement des rainures de culture. Les rainures de culture commutent entre l'état d'afflux d'eau et l'état de reflux d'eau au moyen d'un coulissement. Une extrémité d'un passage de sortie d'eau est en communication avec la voie d'eau de rainure de sortie d'eau de la rainure de culture correspondante, et l'autre extrémité du passage de sortie d'eau est en communication avec le passage d'entrée d'eau d'une étagère hydroponique inférieure. Etant donné que les rainures de culture commutent entre l'état d'afflux d'eau et l'état de reflux d'eau au moyen d'un coulissement, le temps de drainage dans l'état de reflux d'eau peut être efficacement réduit.
