The present invention relates to a method for producing a hydroponic cultivation medium, which has excellent chemical and physical properties and uses chaff or hultan chaff having excellent characteristics as a hydroponic cultivation material as a main raw material, and has good absorbency and excellent binding force. As a binder, and by adding cokenut fibers and super absorbent polymers to increase water holding capacity and inhibit hardening of the medium, it possesses excellent characteristics as a hydroponic cultivation medium and does not cause environmental pollution upon disposal after use. It is an object of the present invention to provide a method for preparing a medium.;In the present invention, in the method for producing hydroponic rice hull shaping medium, using chaff or Huntan chaff as the main raw material, adding 10 ~ 30wt% to the total weight of waste paper or pulp made by crushing as a binder to increase the water holding capacity and In order to prevent hardening of the medium, coconut fiber is added by mixing 10 ~ 20wt% of the total weight and super absorbent polymer 3 ~ 8wt% by the total weight, and then mixed with arbitrary mixing water and poured into the mold, and then under reduced pressure A method of producing hydroponic rice hull forming medium for hydroponic cultivation is carried out by first dehydrating, secondly depressurizing and molding under pressure of 0.1kgf / cm2 or more, to prepare a hydroformed body, and then drying until no weight change occurs in the dryer. That's the point.
