VERTICAL-TYPE HYDROPONIC SYSTEM, AND VERTICAL-TYPE HYDROPONIC METHOD

摘要

PROBLEM TO BE SOLVED: To provide a vertical-type hydroponic system that prevents root rot of a cultivated plant, and can efficiently cultivate a plant by supplying a small amount of nutritious liquid.;SOLUTION: A vertical-type hydroponic system comprises: a plurality of vertical-type hydroponic cylinders 1 which are suspended on a ceiling or erected on a floor surface of a greenhouse; culture medium 2 which is housed in the vertical-type hydroponic cylinder 1 in an insertable and extractable manner; nutritious liquid supply means 4 which supplies nutritious liquid 7 from a nutritious liquid housing tank 3 to the culture medium 2; and nutritious liquid recovery means 5 which collects the nutritious liquid 7 dropped from a lower part of the vertical-type hydroponic cylinders 1 and recovers the liquid into the nutritious liquid housing tank 3, in which the vertical-type hydroponic cylinder 1 includes a slit 11 in a vertical direction for planting a plant seedling on one side face thereof, the culture medium 2 is constituted of a water-retaining sheet 21 and an air-permeable material sandwiching both faces of the sheet, an upper end part of the water-retaining sheet 21 protruded from an upper end of the air-permeable material is mounted in a folded manner on the top face of one air-permeable material, and the nutritious liquid 7 is dropped onto the water-retaining sheet 21, which is mounted in a folded manner, from the nutritious liquid supply means 4.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
