초록

참외에서의 관비재배기술 개발을 위하여 배양액의 공급횟수가 토양의 EC 변화, 질소와 칼슘 집적, 덩굴의 생장, 과실의 수량 및 품질에 미치는 영향을 조사하였다. 관비재배는 관행에 비하여 토양 EC가 $0.8dS{\cdot}m^{-1}$까지 증가 하였으나 관행재배는 $0.68dS{\cdot}m^{-1}$에서 $0.2dS{\cdot}m^{-1}$로 낮아졌다. 정식 후 20일 된 식물체의 덩굴길이는 큰 차이가 없었으나 건물중은 관비재배구가 증가하였는데 2회(오전 9시와 오후 6시, 900L/1,000포기, 매일)처리구가 현저히 많았다. 토양 내 질소함량에는 큰 차이가 없었으나 칼슘은 관비재배구가 현저히 높았다. 관비는 관행재배에 비하여 참외과실의 상품(商品)수량이 증가하였는데 1일 1회(오전 9시)보다 2회 관비재배구가 더욱 많았고 기형과율은 관비재배구가 감소하였다. 1개 과실의 크기와 당도에는 차이가 없었다. 저장기간 동안 과실의 중량 감소는 2회 관비재배구가 현저히 많았다.

Experiments were conducted to investigate the effect of fertigation (fertilizer-added irrigation) on soil EC (electrical conductivity), nitrogen and calcium content in soil, vine growth and fruit yield of oriental melon (Cucumis melo L. var. makuwa Mak.). Soil EC was increased with the frequency of fertigation (Yamazaki's solution for melon, 900 L/1,000 plants, each time) up to $0.8dS{\cdot}m^{-1}$ as compared to that of conventional irrigation ($0.2dS{\cdot}m^{-1}$). Ca content in soil also increased in fertigation fields. Vine dry weigh (20 days after planting) was significantly increased in fertigation plot. Markedly increases in marketable fruit yield and lower rate of off-shape fruit were recorded with the increase in fertigation frequency. Mean fruit weight and soluble solids contents ($^0Brix$) in fruit were not affected by fertigation. Fresh weight loss during storage was significantly higher in fruits harvested from 2 times fertigation (09:00 and 18:00) plot than conventional irrigation and the 1 time fertigation ones.
