본 시험은 7~9월 수확을 위한 고랭지 오이의 비가림 재배시 생력형 유인방법인 아치식의 재배방법을 개발하고자 실시하였다. 아치식의 유인높이(1.5 m, 1.8 m 및 2.1 m), 재식거리(90×40 cm, 90×50 cm 및 90×60 cm) 및 적심절위(20절, 25절, 30절, 35절 및 무적심)를 비교하였다. 비가림하우스 내 지표면 위 2.1 m의 기온은 37℃로 너무 높아, 2.1 mrn에서는 일소현상이 나타났다. 아치식 유인높이 1.8 mrn가 다른 유인높이에 비해 착과율과 상품율이 높았다. 상품수량은 1.8 m에서의 102,691 kg · ha-1로 1.5 mrn의 84,790 kg · ha-1보다 21% 많았다. 재식밀도가 높을수록 노균병 발생율은 증가되었다. LAI는 적심절위가 올라갈수록 높았으며 내부투광율은 재식밀도가 좁을수록 경엽이 밀집되어 낮아졌다. 착과수는 주지보다 측지가 많았으며, 적심절위가 낮을수록 증가하였다. 상품수량은 90×50 cm, 35절 적심구가 98,311 kg · ha-1로 90×40cm, 30절 적심구의 93,807 kg · ha-1보다 5% 증가되었다. 따라서 여름생산을 위한 고랭지에서 오이의 아치식유인 재배시 유인높이는 1.8 m, 재식거리는 90×50 cm 및 적심절위는 35절이 최대의 수량을 얻을 수 있는 재배시스템으로 생각되었다.
Growth and yield of cucumber (Cucumis sativus L.) with arch training method were evaluated on several training heights, planting densities, and topping node orders. Cucumber cultivar 'Eunsung-baekdadagi' was planted on 9 June with three training heights of 1.5, 1.8, and 2.1 m, there planting densities of 90×40, 90×50, and 90×60 cm, and five topping node orders of 20th, 30th, 35th, and nontopping. The plot of 2.1 m training height resulted in the higher sun-scald fruit rates due to the higher temperature above 37℃ in the upper space of plastic house. The plot of 1.8 m arch training height showed higher fruit setting and marketable yield rate compared to the other training heights. The maketable yield rate with 1.8 m height arch training was 102,691 kg · ha-1, 21% higher value than that of 1.5 m. Powdery mildew incidence increased with the increase of planting density. Lower LAI were shown depending on the higher topping node order. Lower light transmission ratio was shown in the higher planting density plots, might be due to the crowded stems and leaves inside those plots. Fruit setting rate was also higher in main stems rather than in lateral ones. Marketable yie이 in 90×50 cm planting distance with 35th node topping treatment was 98,311 kg · ha-1, 5% higher than that 90×40 cm planting distance with 30th node topping treatment. Thus the 1.8 m of training height, 90×50 cm of planting distance, and 35th node topping was evaluated for the effective cultivation condition in arch training of cucumber in highland.
