참외 정식 생력화 및 기계화 정식을 위한 기초자료로 활용코자 금싸라기은천 참외에 신토좌 호박을 호접하여 9cm폿트에 45일간 육묘하여 1월 16일 정식하였다. 정식 깊이는 모종을 폿트에서 뽑아 땅에 올려놓는 0cm깊이 정식구, 모종을 폿트 높이의 1/2만 묻는 4.5cm 깊이 정식구, 폿트 높이까지만 묻는 9cm 깊이 정식구(표준), 폿트 높이보다 깊게 묻는 12cm 깊이 정식구로 나누어 비교하였다. 1월 18일부터 19일까지의 터널 최저온도는 9.3℃, 최고온도는 41.2℃이었으며 습도는 59~99%이었다 정식 후 활착은 정식깊이가 깊을수록 빨랐으나, 정식 40일 후의 생육은 0cm 처리구를 제외한 4.5cm, 9cm, 12cm 깊이 정식구간에는 처리간 차이가 없었다 과중은 4.5cm 깊이 정식구에서 가장 무거웠고 과육두께와 당도는 처리간 차이가 없었다. 정식 깊이가 깊을수록 발효과율이 증가하였고 상품과율은 감소하였다. 10a당 상품수량은 9cm 깊이 정식구의 2,361kg에 비하여 0cm 처리구에서는 2%, 4.5cm 처리구에서는 1% 증가하였으나 12cm 처리구에서는 11% 감소하였다.
This experiment was conducted to investigate planting depth, which applied the basic data for planting growth ability and mechanical planting of oriental melon. 'Gumssaragi-eunchun' variety was approach grafting to 'Shintozoa' and seedling was growing during 45 days in the 9cm pot and then planted on Jan. 16. The comparison of planting plots was carried out for four experimental plots, which were separated into 0cm, 4.5cm, 9cm, standard cultivation, and 12cm planting depth in soil. In the tunnel of vinyl house, the lowest and the highest temperature was 9.3℃ and 41.2℃, respectively, and humidity was 59~99% during Jan. 18 and 19. The faster graft-take rate after planting was the deeper planting depth. The growth of 40 days after planting was not significant in each planting plot, except 0cm experimental plot. Fruit weight was the heaviest in 4.5cm planting depth of experimental plot but sugar content and flesh thickness were not significant in each planting depth. The more depth in planting meant the more increase in fermented fruit rate and decrease in marketable fruit rate. Marketable yield was 2,361kg per l0a in 9cm planting plot, which was 2% and 1% lower than in 0cm and 4.5cm, respectively, and 11% greater than in 12cm planting plot.
