Abstract

Commercial fibers such as two kinds of micro-fiber, flannel, and cotton were analyzed for their nutrient solution absorption capacity to select hydrophilic mat used for the irrigation management by drainage level sensor in perlite bag culture. The selected mat was evaluated in terms of absorption capacity. Cotton had the highest absorption capacity and was revealed to be the most appropriate for the control system.

펄라이트자루를 사용한 수경재배에서 급액관리방식의 일종인 배액전극제어법에 필요한 배액 이동매개체를 선발하기 위해서 시판되고 있는 친수성 매트 중에서 극세사, 융, 면 등의 배양액 흡수속도를 분석했다. 또한, 선택된 매트가 배액전극제어법을 적용하였을 때에도 높은 흡수속도를 갖는지 알아보기 위해 연구를 수행하였다. 실험결과 면이 가장 수분보유력이 뛰어났으며, 배액전극제어법을 적용했을 때에도 가장 적합한 것으로 나타났다.
