HYDROPONIC SYSTEM OF MEDICINAL WOODY PLANTS

摘要

PROBLEM TO BE SOLVED: To provide a hydroponic system that can stably cultivate medicinal woody plants.;SOLUTION: A water supply channel 11 in which a plurality of holes are provided is installed on one side of a water tank 2. The water tank 2 is installed so as to be inclined from a horizontal state by a predetermined angle (angle shown in α in figure) such that a side for which the water supply channel 11 is provided, that is, an upstream side of the nutritious liquid becomes higher. The angle is experimentally obtained through experience based on the size of the water tank 2, the flow rate of nutritious liquid, and the flow velocity of the nutritious liquid required. By installing the water tank 2 in an inclined manner such that the upstream side of the nutritious liquid becomes higher, the flow velocity of the nutritious liquid increases, the nutritious liquid is prevented from stagnating at any place of the water tank 2, and proliferation of bacterium or algae can be suppressed.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
