Abstract

The spacing between plug cells and cell volume of each plug cell for nursing tomato seedlings were studied to know the effects on seedling growth and early yield. There were four treatments. The spacing of plug cells was done (OK) or not (NO) in case of cell spacing. The cell number in a plug tray was set to 40 or 50 in case of cell volume. The growth environment and irrigation regime were the same in all of the treatments during the experiment period. The photosynthetic rates, seedling qualities, yield and yield speed were significantly affected by both of the treatments. The photosynthetic rates and seedling qualities were the best in 40S-OK following by 50S-OK, 40S-NO, and 50S-NO while the yield was the best in 40S-OK following by 40S-NO, 50S-OK, 50S-NO. It means the spacing gives more impact than the cell volume in the stage of nursing but the cell volume gives more impact than the spacing after the stage of nursing. In the conclusion the spacing of plug cells in appropriate nursing stage is needed with the appropriate cell volume to make high quality of seedlings and high yield.

본 실험은 토마토 플러그묘 생산에서 공간처리와 배지부피처리를 함께하여 두 가지 처리가 유묘의 묘소질 및 수확량에 미치는 영향을 구명하고자 수행하였다. 처리는 공간과 배지의 부피별로 각 2처리, 모두 4가지 처리를 두었다. 배지는 동일하되 배지의 부피에 따라 40공과 50공 플러그 육묘판을 사용했고, 각 육묘판에 공간처리를 한것과 하지 않은 것으로 나누어 처리했다(40S-OK, 40S-NO, 50S-OK, 50S-NO). 전 실험기간 중에 처리외의 환경조건과 급액조건은 모두 동일하게 적용하였다. 광합성 속도와 묘소질 분석 및 수확량과 수확속도 모두에서 통계적 유의성이 있게 공간처리와 배지의 부피처리의 영향을 받았다. 광합성 속도와 묘소질에서는 40S-OK, 50S-OK, 40S-NO, 50S-NO 처리 순으로 좋은 결과를 나타내어 공간처리의 효과가 더 크고, 수확량에서는 40S-OK, 40S-NO, 50S-OK, 50S-NO 처리 순으로 많아서 배지의 부피 처리의 영향이 큰 것으로 판단된다. 따라서 고품질 묘 생산과 초기 수확량을 증대하고, 수확속도를 빠르게 하기 위해서는 육묘기에 적절한 공간확보와 배지의 부피를 크게 하는 것이 효과적인 것으로 사료된다.
