최근 생약의 수요 및 재배면적이 증가됨에 따라 약초의 재배기술 확립이 요청 되고 있는바 추대로 인한 수량감소와 품질저하가 크다고 알려진 강활에 대하여 파종방법별로 육묘기 생육과 묘크기에 따른 추대 및 수량성을 구명하고자 시험한 결과는 다음과 같다. 1. 파종방법별 출아율은 파종량이 적고 산파했을 경우에 높아지는 경향을 보였고 묘크기에 있어서는 파종량간에 대차 없었으나 파종방법간에는 조파구에서 생장량이 많은 경향이었다. 2. 묘 분포비율은 중묘>소묘>대묘의 순으로 많았는데 소묘생산을 위해서는 산파로서 밀파$(8l;/33m^2)$ 하는 것이 유리 한 것으로 나타났다. 3. 묘크기에 따른 정식후 생육은 묘의 근경이 굵을수록 개화가 빨라지는 경향이었고 지상부 생육은 조파 소묘 정식이 좋은 경향이었다. 4. 묘크기에 따른 추대율은 대묘 89.6%, 중묘 64.4%, 소묘 36.9% 로 묘가 클수록 높았다. 5. 묘크기에 따른 근비대는 미추대근이 추대근에 비하여 많았고 조파묘보다 산파 묘가 좋았다. 6. 생근수량은 산파 소묘 정식구에서 853kg/10a 으로 가장 증수하였다.
Experiment was conducted to investigate the effects of planting date and planting methods with seedling size on bolting and yield of Ostericum koreanum (MAX.) KITAGAWA Seeding methods were also reviewed to imvestigate their effects on seedling characteristics. This experiment was carried out in Chuncheon during 1988 growing season. The small seeding rate and broadcasting had higher rates of emergence than the others. There was no big difference in seedling size by seedling rate, and more seedling growth was in drilling methods among seed planting methods. The quantity of seedling were produced with the order of medium, small and lastly large seedling. Dense planting $(8l;/33m^2)$ was advantageous in producing small seedling. Large seedling had earlier flowering than the others and growth was good in planting small seedling with drilling method. The rates of bolting by seedling sizes were 89.6% in large, 64.6% in medium and 36.9% in small seedling. Bolting was influenced the root Quality by producing lignified root which had a least commercial value. More root growth was shown in unbolting plant compared to bolting plant seedling and broadcasting had much more root growth than seedling from drilling. Fresh root yield of unbolting plant was higher than that of bolting plant and highest yield was obtained in the broadcasting plot with small seedling.
