Abstract

This study was conducted to collect the basic data fo the development ot hydroponic technique and the efficient promotion of water culture. We have also analysed the water culture associated domestic patent application informations searching for on-line internet site with an admission fee (http://www2.wips.co.kr) from the year 1983 to January, 2006. Fifty nine patent applications related to the hydroponics were searched for in this study. Main patent contents applied were as followed in the order of that nineteen applications about the hydroponic equipments by 32.2%, thirteen applications about the materials used in water culture by 22.0%, eleven applications about the composition of nutrient solution by 18.6%, nine applications about the cultural methods by 15.3%, and seven applications about the cultural media by 11.9%. The compositions of nutrient solution and the cultural methods intended for specific crops were increased in number following five applications about tomato plants and four applications about potatoes. Thirty three patents (55.9%) were mainly applied before the year 2000. Main patent contents were the compositions of nutrient solution before the year 2000 in contrast to the cultural methods and substrates after the year 2000.

수경 재배 관련 기술개발 및 수경재배의 효율화를 위한 기초 자료 수집 측면에서 온라인 특허 검색 유료사이트(http://www2.wips.co.kr)를 이용해 1983년부터 2006년 1월까지의 수경재배와 관련된 국 내 특허출원정보를 분석하였다. 수경재배에 관련된 특허출원은 59건이 검색되었다. 특허의 내용은 수경재배 장치에 관한 것 19건(32.2%), 수경재배 자재에 관한 것 13건(22.0%), 양액의 조성에 관한 것이 11건(18.6%), 수경에 의한 재배방법에 관한 것 9건(15.3%), 수경재배배지에 관한 것 7건(11.9%) 순으로 많았다. 특정의 작물을 대상으로 한 양액의 조성 및 수경에 의한 재배방법의 대상 작물로는 토마토가 5건, 감자가 4건으로 많았다. 특허 출원시기는 전체적으로 2000년 이전에 출원된 것이 33건(55.9%)을 차지하였으며, 2000년 이전에는 양액조성과 자재와 관련된 것이 상대적으로 많았고, 2000년 이후에는 수경 재배방법과 배지에 관한 것이 상대적으로 많았다.
