Installation for cultivating plant cultures

An installation for cultivating plants and the like comprising:

• a cover device for protecting the ground at which the plants are grown from damaging radiation of the sun;
• a support device for supporting the cover device;
• said cover device comprising a number of pivotable, substantially cylindrical parabolic reflectors each having a focal line;
• a respective conduit provided along the focal line of each parabolic reflector for conveying a heat carrier;
• an adjustment mechanism for pivoting the reflectors about their lengthwise axis;
• a circulation system for circulating the heat carrier;
• said circulation system encompassing a feed pump and said conduits;
• a control device for actuating said adjustment mechanism;
• said control device being constucted such that when the sun is shining the reflectors are automatically positionally adjusted in accordance with the position of the sun and simultaneously throw shade upon the ground and the solar energy taken-up by the reflectors is removed;
• a heat storage for the storage of the removed heat;
• said control device having means controlling said circulation system in the absence of the sun's radiation such that said reflectors are aligned with respect to the ground such that heat is radiated from the heat storage to the ground.
