SYSTEM FOR CULTURING PLANT IN HYDROPONIC CULTURE MEDIUM

PROBLEM TO BE SOLVED: To improve the bad drainage, the generation of root rots, and the heterogeneous distribution of nutritious liquids on conventional systems for culturing plants in hydroponic culture media. SOLUTION: This system for culturing plants in a hydroponic culture medium, characterized by disposing a middle plate having water-penetrable holes in a bed to form a space between the middle plate and the inner bottom of the bed, spreading on the middle plate a root-preventing sheet which permits the passage of liquids and air but does not permit the roots of plants, and then charging culture soil on the root-preventing sheet. The system for culturing the plants in the hydroponic culture medium, further characterized by linearly connecting plural bed members to each other to form the bed, spreading a waterpoof film on the inside of the bed, disposing the middle plate on the spread water-proof film to form a space in the bed, and preferably furthermore disposing a liquid-spraying tube having spraying holes formed in the longitudinal direction at distances on the culture soil.
