<P>PROBLEM TO BE SOLVED: To provide a culture medium bag enabling easy and complete separation of roots from solid culture medium after cultivating farm product plants in solid culture medium cultivation. <P>SOLUTION: The culture medium bag is obtained by wrapping the solid culture medium with a water-permeable/root-proofing sheet having water permeability but blocking out development of the roots of farm product plants. The culture medium bag is utilized in a hydroponic method as follows: putting the culture medium bag in a cultivation container; implanting farm product plants on a place outside the water-permeable/root-proofing sheet of the culture medium bag and inside the container; cultivating the farm product plants while supplying nutritious liquid to the culture medium bag; separating the farm product plants from the culture medium bag after finishing cultivation of the farm product plants so as to reuse the culture medium bag. The culture medium bag from which the farm product plants are separated after finishing cultivation of the farm product plants, is sterilized by sunning and thereafter reused in the next hydroponics for other farm products. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
