Abstract

Measuring tray as a component in irrigation control system using drainage electrodes was designed and applied for tomato perlite bed culture, and the effectiveness of the irrigation control system was investigated in terms of cultural development and cultivation costs. Five different types of measuring trays equipped with drainage electrodes were tested and the traditional tray was used as the control equipped with time clock. After the first experiment, "Tube-2" was removed because of instability of water content in the substrate. After second experiment, "Tube-1" was removed because of instability of water content in the substrate and low plant yields. In third experiment, "Up-Board" exhibited the best stability in water contents and yields as well as efficiencies in water and fertilizer utilization. The "Up-Board" was the most economical and the easiest system among the tested trays. Therefore, the "Up-Board" system was concluded as the excellent design to apply for the control method using drainage electrodes for tomato perlite bed culture.

토마토 펄라이트 베드재배에서 급액방법으로 배액전극 제어법을 적용하기 위한 적정 측정틀 개발을 위해 본 실험이 수행되었다. 작물로는 대과종 토마토를 사용하였고, 재배 방법은 자루재배와 동일하게 적용하였으며, 급액제어 방법으로 배액전극 제어법을 적용한 다섯 가지 측정틀 처리와 타이머 제어법을 적용한 한 가지 측정틀 처리를 대조구로 하였다. 1차 실험에서는 배지의 수분함량 안정성 조사로 가장 불안정한 Tube-2 처리를 제외하였고, 2차 실험에서는 배지의 수분함량 안정성과 생육과 수확량을 조사하여 성적이 가장 나빴던 Tube-1 처리를 제외하였다. 3차 실험에서 배지의 수분함량 안정성과 생육 및 수확량에서 우수하였으며, WUE와 FUE가 가장 높았던 Up-Board 처리를 선택하였다. Up-Board 처리는 여섯 가지 처리 중에서 가장 경제적이며 측정틀 제작도 용이하여 베드충진 방식에서 배액전극 제어법을 적용하기에 가장 우수한 측정틀 설계였다.
