DEEP FLOW TECHNIQUE SYSTEM, TEMPERATURE CONTROL SYSTEM, PLANT CULTIVATION FACILITY, AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a means for performing temperature control with saving energy in plant cultivation in facilities.;SOLUTION: A deep flow technique system B includes an aeration means 1 for aerating to nutrient solution B2, and a temperature controlling means 12 for heating or cooling air to be aerated. The device B may be in a form that a cultivation surface is covered with a half-permeable covering material 2 inhibiting invasion of noxious insects. As a result of this, temperature control is performed not in the whole space of plant cultivation facilities but limited to the nutrient solution B2 and a space 3 around plants, so temperature control in plant cultivation in the facilities is performed with saving energy.;COPYRIGHT: (C)2011,JPO&INPIT
