MULTISTAGE NUTRITIOUS LIQUID CULTIVATION AND VEGETABLE GARDENING SYSTEM USING SUNSHINE BY PLASTIC LIGHT CABLE

摘要

PROBLEM TO BE SOLVED: To efficiently carry out a nutritious liquid cultivation of energy saving type at a low cost by making a three-dimensional nutritious liquid cultivation. SOLUTION: A sheath 3 of a receiver 2 at the tip of a plastic light cable 1 is peeled to expose a core part 4. A light receiving amplifier 7 obtained by forming a plastic of the same material into a chevron shape 5/a cylindrical shape 6, etc., is stuck fast to the core part. A sunshine energy collected and accumulated by a sunshine collecting convex lens 8 is supplied through the plastic light cable to a second culture tank 10 and a third culture tank 11 of a nutritious liquid cultivation and vegetable gardening facilities 9 out of the sun assembled in a multistage. The facilities are made into a three-dimensional structure from a restriction on a plane of a light environment in a greenhouse culture. The sunshine is dispersed and transmitted by illuminators installed on a top part tank frame and a second tank frame guided from the plastic light cable and adjusts a light environment in a plant culture and enlarges a culture area.
