PURPOSE:To cultivate plant in high efficiency without the need for using any special equipment by using a gel-like carrier with a hydrogen peroxide- decomposing catalyst and/or magnetic substance includedly immobilized. CONSTITUTION:A plant is cultivated using a gel-like carrier with a hydrogen peroxide-decomposing catalyst and/or magnetic substance includedly immobilized. For said carrier, a water-soluble polymeric gel can be used (e.g. agar-agar, sodium alginate, polyvinyl alcohol). The concentration of the carrier is pref. ca. 0.1-10wt.% based on the aqueous solution prior to gelling. Said catalyst is e.g. an enzyme such as catalase, metal, metal oxide. Said magnetic substance is pref. paramagnetic or ferromagnetic. It is effective that the catalyst be a magnetic substance. When a plant is to cultivate using the above-mentioned gel-like carrier, an aqueous solution containing hydrogen peroxide (its concentration being pref. 10-300ppm) is pref. fed to the carrier. |
