<P>PROBLEM TO BE SOLVED: To provide a super-forcing cultivation system eliminating work of poor operability, such as carrying in and out and setting with night coldness, cooling and warming, and air blasting, improving operability of other work, achieving severe allowable error of set temperature and set time, and made wholly compact to suppress loss of energy, and as a result, economically performing temperature control with good operability. <P>SOLUTION: This super-forcing cultivation system includes a plurality of seedling bed containers which each hold culture soil on which seedlings are planted dividedly in a plurality of rows, a supporting stand for loading the containers on, a first heat pipe which is set near the top of the culture soil or in the culture soil in the middle part of a plurality of the seedling rows, and a second heat pipe which is set on the supporting stand. The first and second heat pipes each have coaxial inner tube and outer tube which are substantially placed on the level. A space between the inner tube and the outer tube is made vacuum, and operating fluid is sealed therein, and the second heat pipe is further coaxially held in a third tube having a plurality of openings on a tube wall. <P>COPYRIGHT: (C)2008,JPO&INPIT |
