FIELD: agriculture.SUBSTANCE: invention relates to the field of plant growing without the use of soil. Leaves (91) of the grown plant are obtained by cutting the lower portion of leaves (92) from the root of the grown plant. Device comprises an element with fluid channel (41) formed with a fluid passage through which supply fluid (44) passes. Element (41) is provided with a plurality of through holes on the upper surface of fluid channel element (41) separated from each other at a predetermined interval and disposed along the fluid passage. Device also comprises growth medium (44) for seedlings on which plant seeds are located. Site for retaining nutrient medium (45) of a cylindrical shape accommodates the seedling nutrient medium for its retention, is disposed in a plurality of through-holes of fluid passage element (41) and absorbs the nutrient fluid into the seedling nutrient medium. Support portion of leaf (46) is cylindrical, located on the upper side of the containment section, and supports leaves (91) that were obtained from the seeds, on the periphery of the leaves (91). Nutrient holding portion (45) and leaf holding portion (46) are formed in such a way that the cutting device used to separate the seedling and leaf culture medium (44), can be inserted from the outside into the boundary portion between containment area (45) and leaf support portion (46).EFFECT: provides retention of plant leaves with the possibility of cutting them from the roots.10 cl, 13 dwgИзобретение относится к области выращивания растений без использования почвы.
