Cultivating experiments on the plant transfer equipment developed in this study were conducted, and it was found that stabled cultivations would be nearly possible, but some problems were made clear. To solve these problems and cut the production costs, the plant transfer equipment was improved. The improved points are: power and driving method, carriers, frame, cultivating bed and root intervals. Futhermore, in order to find out cultivating problems which appear in the long working terms, a practical plant was made which could control cultivating conditions completely.
