초록

최근 육성된 곰취 신품종 ‘쌈마니’의 고랭지와 평난지 다수확재배를 위한 적정 재식거리를 구명하고 자 본 연구를 수행하였다. 재배지역은 표고가 해발 750 m인 고랭지와 해발 20 m인 평난지에서 하였으며, 재식거리는 20 x 20, 20 x 30, 30 x 30, 35 x 40, 40 x 40 ㎝ 등 5처리를 하고 난괴법 3반복으로 정식하고노지에서 35% 차광재배를 하였다. 1년차 ‘쌈마니’ 품종의 생육은 평난지보다 고랭지에서 컸으나 엽수는 고랭지보다는 평난지가 많게 나타났고, 재식거리간에는 40 x 40 ㎝구가 가장 많았고재식거리가 넓을수록 많은 경향이었다. 그러나 주당 엽중은 평난지보다 고랭지가 더 높게 나타났다. 10a당 엽수는 고랭지보다평난지가 많았으며, 재식거리가 좁을수록 많은 경향을 보였고, 평난지 20 x 20 ㎝ 재식구에서 543.5천매로 가장 많았다. 수량은 평난지보다 고랭지가 약간 많은 편이었으며 20 x 20 ㎝ 재식구에서 2,983 ㎏/10a로 가장 많았다. 2년차에도 생육은 고랭지가 컸으며 엽수와 엽중에서도 고랭지가 높게 나타났으며 수량에 있어서도 같은 경향이었다. 재식거리간에는 2지역 모두 재식거리가 좁은 20 x 20 ㎝ 재식구에서 높았는데 평난지는 3,369 ㎏/10a, 고랭지는 7,257 ㎏/10a로 나타났다. 3년차의 생육은 고랭지가 평난지보다 약간 좋은 편이나 큰 차이를 보이지 않았으며 경직경은 유사하였다. 그러나 주당 엽수와 엽중에 있어서는고랭지보다는 평난지에서 많았으며 재식거리간에는 재식거리가 넓을수록 많아지는 경향을 보였다. 그러나 10a당 엽수와 수량을 보면 역시 고랭지보다 평난지가 많았으며 재식거리간에는재식거리가 좁을수록 수량성이 높아 평난지 20 x 20 ㎝ 재식구에서 6,051 ㎏/10a로 가장 높게 나타났다. 3년간의 수량 변화를보면 평난지는 3년차까지 계속 높아지나 고랭지에서는 2년차가가장 많고 3년차에는 약간 떨어지는 경향을 보였다. 재식거리 간에는 2지역 모두 재식거리가 좁을수록 수량이 많고 잎의 크기는 작아지는 경향이었다.

This study was carried out to investigate the optimum cultivation distance for high yielding cultivation of the new variety of Gomchwi in highland and lowland. The test material was used ‘Sammany’ variety and the area was cultivated with a highland of 750 m above sea level and a lowland of 20 m above sea level. The planting distance was 5 treatments of 20 x 20 ㎝, 20 x 30 ㎝, 30 x 30 ㎝, 35 x 40 ㎝ and 40 x 40 ㎝, and the plant was cultivated at 35% shading net in the open field. The annual growth of ‘Sammany’ variety was higher in the highland than in the lowland, but the number of leaves was higher in the lowland than that in the highland. The leaf number per plant was the highest in the 40 x 40 ㎝ plot and the more the planting distance was, the more tendency was. However, the leaf weight per plant was higher in the highland than in the lowland. The number of leaves per 10a were higher in the lowland than that of highland and the tendency was more as the planting distance was narrower. Yields were slightly higher in the highland than that of lowland and the highest treatment plot was 2,983 ㎏/10a in 20 x 20 ㎝. In the second year, the growth was high in the highland, and the highland was high in the leaf number and leaf weight and the same tendency in the yields. Among the planting distances, Yields in both areas were the highest in the 20 x 20 ㎝ treatment, with 3,369 ㎏/10a in lowland and 7,257 ㎏/10a in highland. The growth of the third year was slightly better in the highland than that of the lowland but the difference was not significant. However, the number of leaves and leaf weight per plant were higher in the lowland than that of highland. And, in terms of leaf number and yield per 10a, it was also higher in the lowland than that in the highland. The narrower the planting distance was increased yields, and the highest yield was 6,051 kg/10a in 20 x 20㎝. The lowland was high in yield until the third year, but the highland was the highest in the second year and decreased slightly in the third year. The narrower the planting distance in the both areas, the higher the yield, and the leaf size tended to be small.
