Abstract

A multipurpose operating system was developed to adjust both spray times and ventilation method without a configuration of the moving path and the type of the greenhouse. The multipurpose working system proved to be a reliable system for testing the growth quality of the fruit vegetables in the greenhouse. The results are as follows. The first leaf, diameter of a stem, leaf area, and average stem diameter in the Cucumber seedling growth were repressed by high-speed ventilation, but was not repressed by spray times. The first leaf in the Tomato seedling growth was repressed as ventilation velocity was high, but the average stem diameter was not repressed. While the Tomato was given water three times a day, the diameter of a stem and the leaf area were increased as ventilation speed became higher. However, those were different other factors. The Tomato leaf area was larger when given water twice a day than that in hand spray, but showed no difference with ventilation speed. The first leaf, the diameter of a stem and the leaf area of a Red pepper were lower in automatic spraying with ventilation than those in hand spray.

본 연구에서는 주행경로의 설정 및 제어가 용이한 고정 경로 방식을 이용한 주행 시스템을 개발하여 온실의 형태, 고랑의 위치 등에 무관하게 자동관수 및 송풍장치에 따른 생육상태를 실험할 수 있는 다목적 자동작업시스템을 개발하였다. 이 시스템의 성능들을 알아보기 위해 과채류에 대하여 실험한 결과 다음과 같은 결과를 얻었다. 오이는 초장, 줄기 지름, 엽면적 및 줄기 한마디의 평균 길이에 있어서 고속송풍에 따른 억제효과가 나타났으나, 관수 회수에 따른 차이는 크지 않았다. 토마토는 송풍처리에 따라 송풍속도가 강할수록 초장이 억제되는 효과를 나타냈다. 줄기의 지름은 처리구간 큰 차이를 나타내지 않았다. 3회 관수처리구의 경우 송풍속도가 강할수록 줄기의 지름이 두꺼워지는 경향을 나타내었다. 엽면적은 대조구(Hand spray)에 비해 2회 관수처리구의 엽면적이 높게 나타났으며, 송풍속도에 따른 차이가 나타나지 않았다. 고추는 전체적으로 대조구에 비해 자동관수 처리구와 송풍처리구가 초장, 줄기의 지름, 엽면적 등이 낮게 나타났다.
