벼 자동화 육모시설에서 Container 구조가 묘생육에 미치는 영향 = Effect of Nursery Container Structure on Seeding Growth in Automatic Facility for Raising Seedling of Rice

국문 초록 (Abstract)

건전묘 생산을 위한 육묘 콘테이너의 선반 간격과 상자간의 배치간격을 달리하여 육묘하면서 이들이 모 생육에 미치는 영향을 조사하여 얻어진 결과를 요약하면 다음과 같다.
콘테이너의 선반 간격이 17cm에서 23cm로 넓어짐에 따라 묘초장이 증가하였고 그 증가폭은 6월 10일 파종에서보다 5월 10일 파종에서, 육묘일수가 길어질수록 큰 편이었다.
콘테이너의 선반간격뿐만 아니라 상자간의 배치간격도 모의 생장에 미치는 영얗이 매우 컸으며 상자의 배치간격이 넓을수록 초장이 짧아지고 묘충실도는 증가하는 경향이었다. 육묘 콘테이너에 치상된 육묘상자의 위치에 따른 조도는 하단에서 상단으로 올라갈수록 높아졌고, 묘초장은 상단에서 하단으로 갈수록 큰 편이었다.
육묘콘테이너의 선반간격을 20cm로 하고 육묘상자와 상자사이를 3cm 정도 띄웠을 때 모의 황화현상은 크게 감소하였다.

This study was conducted to determine the optimum intervals of shelves and seed-tray layout in container for raising rice seedlings at automatic facility. The seedling characteristics were evaluated with 10-day to 20-day old seedling grown under the different intervals of nursery shelves and seed-tray arrangement in the containers.
The plant height was increased as the shelf intervals in nursery containers from 17 cm to 23 cm. The difference in plant height was larger in seedlings seeded at May 10 than those at June 10 and in 20-day old seedlings as compared with 10-day old seedlings. The growth characteristics of seedlings was significantly varied with the layout intervals of nursery tray on the containers. The seedling height was shorter as the extension of layout intervals of the tray on the shelf of nursery containers, but gthe seedling quality was increased in the seedling which grown on the trays arranged at 3 to 5 cm intervals. The light intensity eas remarkably different from the position of nursery tray in the container. The illumination intensity was the ghghest on the uppermost tray. However the seedling height was shorter as the raising of tra position from the lowest shelf go the highest it in nursery container. The best results based on the seedling characteristics was obtained from the seedlings which grown in the tray arranged at 3 cm interval on the ten-shelf container with 20 cm intervals.
