| Research Abstract |
The compressed solid beds are widly current in hydro-cultivation systems, but these utilization encounter various handling problems including environmental pollutions. From the above, the objective of this study is to make it able to apply to the hydro-cultivation system of the biomass compossed solid bed which is made with bark materials of Japanese ceder and cypress.
This paper is dealt with the chemical components of the biomass material and physical properties related to water absorption, drying and compressive strength to be able to apply biomass solid beds to the hydro-cultivation.
From the experimental results, the dark of Japanese ceder and cypress as biomass contains antibacterial components and have the power of molding. The rate of three-phase (rate of water, air and solid under the condition of water absorption) of the biomass bed is similar to that of soil. It the case of the rock wool bed, the rate of water content is more higher than that of the biomass bed.
